3.6 The Income Statement

The components of an income statement and how to use one to evaluate performance.

Transcript (190 lines)

0:00 At close on the last day of the month, Cami wipes the whiteboard by the sealing
0:04 machine and adds up a month of daily cup counts: three thousand cups.
0:10 Three years ago, that total would have ended its night as a glance at a
0:14 banking-app balance that looked healthy right up until a sales-tax bill nearly hit
0:18 payroll.
0:19 Tonight it starts a single page that answers two questions the app never could.
0:24 Did Steep Street Boba make money this month, and how much of every six-dollar
0:28 cup did the shop keep?
0:30 That page is the income statement, and this topic builds it line by line.
0:35 I'm Logan Shaffer, and this is MAMAKO's AP Business,
0:38 Topic 3.6: The Income Statement.
0:42 Two skills by the end: build an income statement line by line,
0:45 from revenue down to the bottom line, and use its margins,
0:49 percent changes, and projections to judge a business and plan the months ahead.
0:53 Practice questions for this topic are in the next video.
0:57 Let's go.
0:59 An income statement, also called a statement of profit and loss,
1:03 compares a business's total revenue to its total costs over a period of time to
1:08 determine its net profit or loss.
1:11 The period can be a month, a quarter, or a year; Steep Street builds one
1:16 every month.
1:17 The statement measures a stretch of time rather than a single day,
1:21 and a typical statement prints several periods side by side,
1:24 this month beside last month, this February beside last February,
1:29 because readers judge each line against the same line from the prior period.
1:33 Everything on the page sorts into three major categories,
1:37 revenue, cost of goods sold, and operating expenses,
1:41 and the statement also identifies interest, taxes, and any nonrecurring
1:45 expenses on their own lines.
1:48 This is the first card in the shop's statement stack;
1:51 the balance sheet and the cash flow statement join it across the next two
1:54 topics.
1:57 Revenue is the income generated by the business's core activities.
2:02 Steep Street's core activity is selling cups of boba:
2:05 three thousand cups this month at a six-dollar average is eighteen thousand
2:09 dollars, the top line.
2:11 When Cami caters a graduation, that fifteen-hundred-dollar boba bar counts as
2:16 roughly two hundred fifty cups inside the same line.
2:20 The shop sells cups, so everything it earns counts as cups,
2:23 and no separate catering line exists.
2:26 Cost of goods sold, COGS, is the direct cost of producing what was sold:
2:31 the tea, milk, tapioca, syrup, cup, lid, and sealing film in each
2:37 drink.
2:38 A dollar fifty per cup times three thousand cups is four thousand five
2:42 hundred dollars.
2:44 Revenue minus COGS is gross profit, the profit remaining after only the direct
2:48 costs of production: eighteen thousand minus four thousand five hundred is
2:53 thirteen thousand five hundred dollars.
2:58 Operating expenses are the indirect costs of running the business,
3:02 and statements typically organize them into two groups.
3:06 Selling expenses pay for the selling of the product:
3:09 sixty-two hundred dollars of counter staff wages and three hundred dollars of
3:14 marketing.
3:15 General and administrative expenses pay for running the business behind the
3:19 counter: twenty-five hundred dollars of rent, four hundred of utilities,
3:24 two hundred fifty of insurance, and two hundred fifty of supplies and
3:28 miscellaneous.
3:30 Research and development spending belongs in operating expenses too;
3:34 if Cami paid a food lab to formulate a new flavor line,
3:38 that cost would join these lines.
3:40 The total this month is nine thousand nine hundred dollars.
3:44 Gross profit minus operating expenses is operating profit,
3:48 the business's income before interest and taxes: thirteen thousand five hundred
3:52 minus nine thousand nine hundred is three thousand six hundred dollars.
3:59 Interest expense is the cost of borrowing money, through loans at the shop's scale
4:04 and through bonds at corporate scale.
4:07 Steep Street's equipment loan payment is three hundred dollars a month,
4:10 two hundred fifty of principal and fifty of interest,
4:13 and only the fifty of interest is an expense here; the principal repays the
4:18 debt itself, and debts live on the next topic's statement.
4:22 Operating profit minus interest expense is pretax income:
4:26 three thousand five hundred fifty dollars.
4:29 Pretax income is positive, so the shop owes taxes on it,
4:33 and the tax expense goes on the statement: at twenty percent,
4:36 seven hundred ten dollars.
4:38 Pretax income minus taxes is net profit: two thousand eight hundred forty dollars.
4:45 Accountants call this the bottom line, and it is the income the business earned for
4:49 its owners over the period.
4:51 One note lands here once, for the whole unit.
4:54 Cami pays herself an owner's draw of about two thousand dollars a month,
4:58 and that draw comes out of the net profit.
5:01 It is never an operating expense, so a statement that lists the owner's pay
5:05 inside operating expenses is built wrong.
5:08 One category remains: nonrecurring expenses, one-time costs that will not
5:13 repeat.
5:14 If the ice machine failed and the repair cost six hundred dollars,
5:17 that repair would appear on its own labeled line, so a reader knows next
5:21 month's statement will not carry it.
5:25 Each profit line on the statement converts into a margin:
5:29 the profit at that stop divided by total revenue.
5:32 Gross profit margin is gross profit over revenue, thirteen thousand five hundred
5:37 over eighteen thousand, seventy-five percent, and it grades pricing and
5:42 direct-cost control: whether six dollars is the right price and a dollar fifty the
5:48 right cost per cup.
5:50 Operating profit margin is operating profit over revenue,
5:54 three thousand six hundred over eighteen thousand, twenty percent,
5:57 and it grades how well the business markets and sells its product and controls
6:02 the cost of administering itself.
6:04 Net profit margin is net profit over revenue, two thousand eight hundred forty
6:09 over eighteen thousand, fifteen point eight percent,
6:12 just under sixteen, and it grades overall profitability:
6:16 just under sixteen cents of every revenue dollar flows through to the owner.
6:23 No margin means anything alone.
6:25 Margins are benchmarked against the business's own projections,
6:29 its past performance, and its competitors, and the comparison decides whether
6:33 performance is meeting expectations.
6:36 Internal and external stakeholders read the same page:
6:39 Cami spots trends and decides what to fix, the bank reads it as the first page of
6:44 the packet she submits this spring, and the grandmother who co-signed the
6:48 equipment loan reads every statement Cami sends her.
6:53 The comparison column has its own equation.
6:55 Percent change equals current value minus initial value,
6:59 divided by initial value, times one hundred, and it runs on any line of the
7:04 statement: revenue, a cost, a profit, a margin.
7:09 Run it on the shop's worst month.
7:11 Last February, revenue was twelve thousand dollars.
7:15 This February, an eight-day water-main closure shut the shop's street,
7:20 and three of those days fell inside the month; revenue came in at ten thousand
7:24 eight hundred.
7:26 Ten thousand eight hundred minus twelve thousand is negative twelve hundred.
7:30 Twelve hundred lost, divided by the twelve thousand it started from,
7:35 times one hundred: negative ten percent.
7:41 The equation measures the drop; it never explains it.
7:44 Cami supplies the explanation, three closed days on top of the usual winter
7:49 trough, and a reader who sees the number without the explanation grades February
7:54 wrong. That is why stakeholders track statements across multiple periods:
7:59 trends in revenue and cost, measured as percent changes,
8:03 turn one month's page into a judgment about where the business is heading.
8:09 Every line so far recorded a month that already happened,
8:13 built from current financial data: the whiteboard counts,
8:16 the supplier invoices, the payroll runs.
8:19 A projected income statement runs the same page forward,
8:23 built from predictions.
8:24 Businesses plan this way because incomes and expenses fluctuate:
8:28 needs and wants shift, competitors press, and the outside PESTEL forces move,
8:33 a tapioca price jump, a minimum-wage change, a street that closes for eight
8:38 days without asking.
8:40 Planning converts those surprises into line items a business can prepare for.
8:44 Projected statements and budgets estimate every expense of running the business and
8:49 the revenue expected from projected production and sales.
8:52 Cami builds July's projection every spring.
8:55 Future revenue is estimated from planned pricing and market research about customer
8:59 demand: her price holds at six dollars, and three years of July history,
9:04 school out and heat up, say volume climbs to about forty-two hundred cups,
9:09 so projected revenue is twenty-five thousand two hundred dollars.
9:13 Future costs are estimated from the planned production behind that volume:
9:17 forty-two hundred cups at a dollar fifty of ingredients and packaging is
9:21 sixty-three hundred of projected COGS, and gross profit projects to eighteen
9:25 thousand nine hundred, the same seventy-five percent.
9:30 The operating lines mostly hold, because rent and insurance do not care what month
9:34 it is; wages are the one line she plans upward, extra shifts for the rush,
9:39 and the tax estimate grows with the profit.
9:42 The projection does the three jobs the planning is for:
9:45 it lays out expected costs before they arrive, it shows the funding she needs,
9:50 because the pre-bought tapioca order does not pay for itself,
9:53 and it tells her how much cash must sit ready to meet obligations while the busy
9:58 month runs.
10:01 Consumers run the same document under a different name.
10:04 A consumer budget starts from expected net pay, income after taxes and other
10:09 deductions, and allocates every planned saving and expense for the period,
10:13 including debt payments.
10:15 Sadie's card: about one hundred forty dollars of net pay a week from Hillcrest
10:19 Market, five hundred sixty dollars in a four-week month.
10:24 Her lines: one hundred sixty to savings, forty for her share of the phone plan,
10:29 sixty for transport, one hundred twenty for food and fun,
10:33 forty for gifts and other, twenty repaying the advance from her parents,
10:37 which is the debt-payment line every budget must carry,
10:40 and one hundred twenty of unallocated buffer.
10:43 Line for line, this is a personal projected income statement:
10:47 expected income at the top, planned outflows underneath,
10:51 a bottom line of slack.
10:53 The budget is how she sees her spending patterns and checks her goals:
10:57 the festival fund filling on schedule, the debt shrinking twenty dollars a month,
11:01 the gifts line covering donations to causes she supports.
11:05 The shop's projection and her budget are the same discipline at two scales.
11:11 That's Topic 3.6.
11:14 One page now turns three thousand cups into a bottom line of two thousand eight
11:18 hundred forty dollars and grades the shop three times on the way down.
11:24 But the income statement is a movie of one month, and some questions a movie cannot
11:28 answer: what does Steep Street own, what does it owe,
11:32 and what is the business worth on any given day, the questions a lender asks
11:37 before it lends and a household asks before retirement.
11:41 The snapshot that answers them is Topic 3.7, The Balance Sheet and Net Worth.
11:47 If this helped, a like tells YouTube to show it to more first-cohort students,
11:52 and subscribing gets you the whole course, in order,

12:07 See you next time.

What an income statement is

An income statement, which also goes by the name statement of profit and loss, sets everything a business earned across a period against everything it spent, and the difference is that period's net profit or loss. A period here can run a month, a quarter, or a year. Because the page measures a stretch of time and not a single day, most statements print more than one period at once, the current month next to the one before it, or this quarter next to the same quarter last year, which lets every line be judged against its own history.

Three major categories absorb almost everything on the page: revenue, cost of goods sold, and operating expenses. Interest, tax, and any nonrecurring cost then take separate labeled lines of their own. Nonrecurring means exactly what it says, so a one-time equipment repair is given its own label and a reader knows the next period will not carry it.

From revenue to gross profit

Revenue is the income generated by the business's core activities. For a shop selling 3,000 units in a month at a $6.00 average, revenue is $18,000, and that is the top line. Where a business sells one thing, everything it earns counts inside that line, so a $1,500 catered event booked at the same average price counts as roughly 250 units rather than opening a second revenue line.

Cost of goods sold is the direct cost of producing what was sold, which here is $1.50 per unit across 3,000 units, or $4,500. Revenue minus COGS is gross profit, the profit remaining after only the direct costs of production: $18,000 minus $4,500 is $13,500.

Gross profit = Revenue - COGS

From operating expenses to operating profit

Operating expenses gather the indirect costs of keeping the business running, and a statement usually splits them into two named groups. Selling expenses pay for selling the product, covering advertising and the pay of the people who sell. General and administrative expenses pay for running the business behind the counter, covering rent, utilities, insurance, and supplies. Research and development spending belongs in operating expenses as well.

With $6,200 of counter wages and $300 of marketing on the selling side, and $2,500 of rent, $400 of utilities, $250 of insurance, and $250 of supplies on the administrative side, the total is $9,900. Gross profit minus operating expenses is operating profit, the business's income before interest and taxes: $13,500 minus $9,900 is $3,600.

Interest, taxes, and the bottom line

Interest expense is the cost of borrowing money, through loans at small scale and through bonds at corporate scale. Only the interest portion of a loan payment appears here. On a $300 monthly payment split $250 of principal and $50 of interest, the statement reports $50, because the principal repays the debt itself and debts live on the balance sheet. Operating profit minus interest expense is pretax income: $3,600 minus $50 is $3,550.

If pretax income is positive the business owes taxes on it, and the tax expense appears on its own line. At 20% that is $710, so pretax income minus taxes is net profit of $2,840. This figure is what accountants mean by the bottom line, and it represents what the period actually earned on behalf of the people who own the business.

The margin cascade

Each profit line converts into a margin, which is that stop's profit divided by total revenue. Gross profit margin is $13,500 over $18,000, or 75%, and it grades pricing and direct-cost control. Operating profit margin is $3,600 over $18,000, or 20%, and it grades two things at once: how effectively the selling effort works, and how tightly the cost of administering the place is held. Net profit margin is $2,840 over $18,000, or 15.8%, and it grades overall profitability, reading naturally as just under sixteen cents of every revenue dollar reaching the owner.

No margin means anything on its own. Each one is benchmarked three ways, against what the business projected, against what it achieved before, and against what comparable businesses achieve, and only that comparison decides whether performance is meeting expectations. Both internal and external stakeholders read the same page: an owner spots trends and decides what to fix, while a lender reads it as the first page of a loan packet.

The percent change equation

% Δ = \frac{V_{1} - V_{0}}{V_{0}} \times 100

The comparison column has an equation of its own, and it works on any line at all, whether that line holds revenue, a cost, a profit, or a margin. Take a February that produced $10,800 of revenue against $12,000 the February before. The change is negative $1,200, and $1,200 divided by the $12,000 it started from is 10%, so revenue fell 10%.

The equation measures the drop and never explains it. If three days of a street closure fell inside that month, only the business can supply that fact, and a reader who sees the number without the explanation grades the month wrong. This is precisely why stakeholders track statements across multiple periods rather than judging one page alone: trends in revenue and cost, measured as percent changes, turn a single month into a judgment about direction.

Projected income statements and consumer budgets

Everything above recorded a period that has already closed, assembled out of data the business actually collected. A projected income statement points the same page forward and fills it with predictions instead. The reason a business plans this way is uncertainty: what customers need and want shifts, competitors apply pressure, and the PESTEL forces outside keep moving. Revenue ahead is estimated from the pricing the business intends to set and from research into customer demand, while the costs ahead follow from the production plan that volume implies.

A projected peak month at 4,200 units and a held price of $6.00 projects $25,200 of revenue, $6,300 of COGS at $1.50 per unit, and $18,900 of gross profit at the same 75% margin. The fixed operating lines mostly hold their level, since neither rent nor an insurance premium notices which month it is, while wages stretch to cover extra shifts. Three jobs follow from the projection: expected costs get laid out before they land, the funding required to pre-buy inventory becomes visible, and the business learns how much cash has to be standing by so obligations are met while the rush is under way.

Consumers run the same document under a different name. A budget begins with expected net pay, the amount that survives taxes and other deductions, then assigns every dollar of it to a planned saving or a planned expense, with debt repayment among them. A $560 four-week month split into $160 of savings, $40 for a phone share, $60 for transport, $120 for food and fun, $40 for gifts, $20 repaying an advance, and $120 of buffer is a personal projected income statement line for line: expected income at the top, planned outflows underneath, and a bottom line of slack.

Worked Examples

Building an income statement from revenue to net profit

Work an income statement top to bottom and arrive at the bottom line.

A shop sold 3,000 units this month at a $6.00 average. Ingredients and packaging cost $1.50 per unit. Operating expenses were $9,900, interest expense was $50, and the tax rate is 20%. Build the statement.

Units sold: 3,000
Average price: $6.00
Variable cost per unit: $1.50
Operating expenses: $9,900
Interest expense: $50
Tax rate: 20%

1. Compute revenue
Multiply units by price. 3,000 times $6.00 is $18,000, the top line.
2. Compute cost of goods sold
Multiply units by the direct cost each one carries. 3,000 times $1.50 is $4,500.
3. Subtract COGS to reach gross profit
$18,000 minus $4,500 is $13,500.
$GP = 18000 - 4500$
4. Subtract operating expenses to reach operating profit
$13,500 minus $9,900 is $3,600, which is income before interest and taxes.
5. Subtract interest expense to reach pretax income
Only the interest portion of a loan payment belongs here. $3,600 minus $50 is $3,550.
6. Apply the tax rate
Pretax income is positive, so tax is owed. 0.20 times $3,550 is $710.
7. Subtract tax to reach net profit
$3,550 minus $710 is $2,840.

Check answer

Answer
$2,840. The month produced $18,000 of revenue and $2,840 of net profit.

Why it matters
Each subtraction answers a different question, which is why the statement has stops rather than one calculation. An owner draw of about $2,000 then comes out of this $2,840 and never appears among the operating expenses above.

Converting three profit lines into three margins

Convert each profit line into a margin and state what each one grades.

Using the same month, with $18,000 of revenue, $13,500 of gross profit, $3,600 of operating profit, and $2,840 of net profit, compute the three margins.

Revenue: $18,000
Gross profit: $13,500
Operating profit: $3,600
Net profit: $2,840

1. Compute gross profit margin
Divide gross profit by revenue. $13,500 over $18,000 is 0.75, or 75%.
2. Compute operating profit margin
Divide operating profit by revenue. $3,600 over $18,000 is 0.20, or 20%.
3. Compute net profit margin
Divide net profit by revenue. $2,840 over $18,000 is 0.1578, or about 15.8%.
$NPM = \frac{2840}{18000}$
4. Read the cascade in cents
Each revenue dollar keeps 75 cents past direct costs, 20 cents past operating costs, and just under 16 cents once interest and tax are paid.

Check answer

Answer
75%, 20%, and 15.8%. The three margins fall from 75% to 20% to just under 16% as each layer of cost is removed.

Why it matters
A single margin proves nothing on its own. What makes these numbers usable is comparison, against the business's own projections, against its earlier months, and against businesses in the same line of work.

Running percent change on a revenue line

Compute the percentage change between two comparable periods and separate measurement from explanation.

February revenue came in at $10,800. The same month a year earlier produced $12,000. Compute the change, then decide what the number does and does not tell a reader.

Current February revenue: $10,800
Prior February revenue: $12,000

1. Find the change in dollars
Subtract the earlier figure from the current one. $10,800 minus $12,000 is negative $1,200.
2. Divide by the initial value
The denominator is always the period being compared against. Negative $1,200 over $12,000 is negative 0.10.
$% Δ = \frac{10800 - 12000}{12000} \times 100$
3. State it as a percentage
Multiply by 100. Revenue fell 10% year over year.
4. Separate the measure from the cause
The equation reports the size of the drop and says nothing about why. If three days of a street closure fell inside the month, only the business can supply that.

Check answer

Answer
negative 10%. Revenue fell $1,200, a decline of 10% against the same month last year.

Why it matters
A percent change is evidence, not a verdict. A reader handed the number without the explanation will grade the month wrong, which is why statements are read across several periods and why a filing that carries a footnote is worth more than one that does not.

Projecting a peak month before it arrives

Build the top of a projected income statement from a volume forecast and a held price.

Three years of history say July sells about 4,200 units. The price holds at $6.00 and the direct cost holds at $1.50. Project revenue, COGS, and gross profit for July, then state what the projection is for.

Projected volume: 4,200 units
Planned price: $6.00
Direct cost per unit: $1.50

1. Project revenue
Multiply the forecast volume by the planned price. 4,200 times $6.00 is $25,200.
2. Project cost of goods sold
Multiply the same volume by the direct cost. 4,200 times $1.50 is $6,300.
3. Project gross profit
Subtract the projected COGS from projected revenue. $25,200 minus $6,300 is $18,900.
4. Check the margin against the norm
Divide $18,900 by $25,200 to get 0.75. The gross margin holds at 75%, which is the sanity check that the projection was built consistently.

Check answer

Answer
$25,200 of revenue and $18,900 of gross profit. July projects to $25,200 of revenue, $6,300 of COGS, and $18,900 of gross profit at the usual 75% margin.

Why it matters
The projection earns its keep before July arrives. It shows the pre-buy of inventory that has to be funded, the extra shifts wages must cover, and how much cash needs to be standing by while the rush runs.

Practice Questions

6 questions. Nothing here is recorded or scored.

Question 13.6.A.2, 3.6.A.5
Milpa Verde
Ines Vega owns Milpa Verde, a taco cart that works a downtown corner on weekday lunches. She buys tortillas, chicken, produce, and foil wrap from a restaurant supplier, rents overnight parking and prep space at a licensed commissary kitchen, pays one helper who takes orders and runs the register through the lunch rush, carries a liability insurance policy, and makes monthly payments on the loan that bought the cart. Each month she builds an income statement from register records and receipts and reads it beside last month's column before changing anything. This month, the organizer of a monthly food-truck rally offered her a paid Saturday spot for a flat vendor fee, and Ines is drafting next month's numbers with the rally included before she says yes.
On Milpa Verde's income statement, which of the following best describes how the cart's costs are organized?
- A.The ingredients, the foil wrap, the commissary rent, the wages, and the insurance are cost of goods sold.
- B.The ingredients and foil wrap are operating expenses, and the rent, wages, and insurance are cost of goods sold.
- C.The ingredients and foil wrap are cost of goods sold, and the rent, wages, and insurance are operating expenses.
- D.The ingredients, the foil wrap, and the helper's wages are cost of goods sold, and the rent and insurance are operating expenses.
Check answerHide answer
Answer: C
A.
This sweeps the whole cost list into one bucket. Necessary is a different test from direct: the rent, the wages, and the premium are every bit as necessary as the tortillas, and only the costs that become part of a taco are COGS.
B.
This runs the split exactly backward: it files the ingredients that go into each taco as overhead and the overhead as direct cost. The tortillas and foil leave the cart inside every order; the rent, wages, and insurance never do.
C.
Correct. An income statement sorts costs into cost of goods sold, the direct costs of producing what was sold, and operating expenses, the indirect costs of running the business around the product. Tortillas, chicken, produce, and the foil wrap go into each taco a customer buys, so they are COGS. The commissary rent, the helper's wages, and the insurance keep the business running whether any single taco sells or not, and statements typically split them further: the helper at the register is a selling expense, and the rent and insurance are general and administrative.
D.
The bait is the helper's paycheck. Wages sort by the job they pay for: Ines builds the tacos, the helper sells them at the register, and selling labor is an operating expense, not a direct cost of production.
Question 23.6.B.2
Ines wants one measure of how successfully the cart is pricing its tacos and managing its ingredient and packaging costs. Which of the following best identifies that measure?
- A.The net profit margin.
- B.The operating profit margin.
- C.The revenue growth rate.
- D.The gross profit margin.
Check answerHide answer
Answer: D
A.
This sits at the bottom of the statement and grades overall profitability, the share of each revenue dollar that reaches the owner, with interest and taxes mixed in. Too many other decisions ride along for it to isolate pricing and ingredients.
B.
One stop too far down. Operating profit margin folds in the rent, the wages, and the marketing, so it grades selling and administration on top of the recipe.
C.
Revenue growth measures how much more the cart sold, not how profitably it sold it. A month of underpriced tacos can grow revenue while the margin on each taco shrinks.
D.
Correct. Gross profit margin is gross profit divided by total revenue, and because gross profit subtracts only the direct costs, the margin isolates exactly two decisions: the prices on the menu board and the cost of what goes into each taco. Any margin only becomes a judgment when it is benchmarked against the cart's projections, its past months, and other food vendors.
Question 33.6.C.2, 3.6.C.3
Which of the following best explains why Ines drafts next month's numbers before accepting the rally spot?
- A.A projected income statement records the revenue and costs the rally has already produced.
- B.Estimating the added revenue and costs in advance shows whether the rally adds profit.
- C.A projected income statement guarantees the rally will be profitable before she commits.
- D.Drafting the numbers moves the vendor fee off the statement, since one-time costs are excluded.
Check answerHide answer
Answer: B
A.
This describes the ordinary income statement, built from current financial data about what already happened; a projection is built from predictions.
B.
Correct. A projected income statement predicts revenues, costs, and the resulting profit or loss for a coming period. Future revenue is estimated from planned prices and expected customer demand at the rally; future costs come from the production behind it: extra ingredients, extra helper hours, the vendor fee. The projection shows whether the rally is expected to add profit and how much cash must be ready before Saturday arrives.
C.
No projection guarantees anything; it is a forecast built from estimates. The value is in the comparison it allows before committing, not in any promise about how the Saturday actually goes.
D.
This misreads one-time costs. A nonrecurring expense appears on its own labeled line so a reader knows it will not repeat; drafting a projection moves nothing off the statement.
Question 43.6.C.4
A part-time bookstore clerk writes out a monthly plan: expected net pay of 900 dollars, allocated as 350 for a rent share, 200 for food, 60 for a bus pass, 120 for savings, 90 for a student-loan payment, 30 for donations, and a 50-dollar buffer. Which of the following best describes the plan?
- A.A consumer budget allocating expected net pay across savings, expenses, and debt.
- B.A consumer budget with one error, because a loan payment is not a planned expense.
- C.An income statement, because it reports what the clerk earned and spent last month.
- D.An incomplete plan, because charitable donations belong outside a consumer budget.
Check answerHide answer
Answer: A
A.
Correct. A consumer budget starts from expected net pay, income after taxes and other deductions, and allocates every planned saving and expense for the period, and debt payments are on the required list. Line for line, a budget is a personal projected income statement, and comparing it afterward with the month that actually happened shows spending patterns and whether the goals are on track.
B.
This invents a rule the framework states in reverse. A consumer budget includes all planned expenses including debt payments, so the 90 dollars belongs exactly where it is.
C.
The plan-versus-record swap. An income statement reports a period that already happened, and every number in this plan is a prediction.
D.
No rule pushes donations outside a budget. A budget allocates expected net pay across whatever the clerk plans to do with it, and a giving line is a planned expense like any other.
Question 53.6.B.4, 3.6.B.6
Milpa Verde Income Statement
Ines finishes this month's income statement, and the table shows it, along with one comparison figure from last month's column.
Line | Amount Revenue | $8,000 Cost of goods sold | $3,200 Gross profit | $4,800 Operating expenses | $3,200 Operating profit | $1,600 Interest expense | $100 Pretax income | $1,500 Taxes | $300 Net profit | $1,200 Net profit, last month | $1,000 Which conclusion is supported by the statement?
- A.The cart's gross profit margin for this month came to 40 percent of revenue.
- B.Revenue grew 20 percent from last month to this month's total.
- C.The cart's operating profit margin for this month came to 33 percent.
- D.Net profit grew 20 percent, and net profit margin is 15 percent.
Check answerHide answer
Answer: D
A.
3,200 over 8,000 is 40 percent, but that is the COGS share of revenue, the complement of the answer. Gross profit margin divides gross profit by revenue: 4,800 over 8,000 is 60 percent.
B.
The table shows exactly one figure from last month, net profit, so a claim about revenue growth has nothing to stand on.
C.
This divides operating profit by gross profit to get 33 percent. Every margin divides by total revenue, and 1,600 over 8,000 is 20 percent.
D.
Correct. Run both halves. Percent change is current value minus initial value, divided by initial value, times 100: 1,200 minus 1,000 is 200, and 200 over 1,000 is 20 percent growth. Net profit margin is net profit over total revenue: 1,200 over 8,000 is 15 percent. Both check out.
Question 63.6.A.7, 3.6.A.9
A pottery studio's annual income statement shows a positive operating profit and a net loss on the bottom line. Which of the following best explains the result?
- A.Cost of goods sold ran greater than the studio's revenue for the full year.
- B.Interest expense on the studio's loans exceeded its operating profit.
- C.Taxes turned a positive pretax income into a net loss for the year.
- D.Operating expenses ran greater than the studio's gross profit for the year.
Check answerHide answer
Answer: B
A.
This would make gross profit negative, and the cascade never recovers: operating profit would come out negative too, and the question says it is positive.
B.
Correct. The statement runs in a fixed order: gross profit, then operating profit, then interest expense, then pretax income, then taxes, then net profit. Interest, the cost of borrowing through loans and at corporate scale through bonds, is subtracted after operating profit. When interest is bigger than operating profit, pretax income goes negative, no income tax is owed on a loss, and the loss carries straight to the bottom line: a studio that runs well but borrowed heavily.
C.
The order kills it. Taxes are only charged when pretax income is positive, and a tax takes a share of that income, so it shrinks a profit and never flips one into a loss.
D.
This fails the same test: operating expenses greater than gross profit would make operating profit negative, and the question says it is positive.
