The Income Statement (Profit and Loss) and Break-Even Point

The income statement, also called the profit and loss statement or P&L, answers the question every owner asks: is my business making money? It lists revenue and expenses for a period (a month, a quarter, a year) and, by difference, shows the profit or loss. Learning to read it is the single most useful accounting skill for a non-accountant, and it's the report your banker, your CPA and any buyer will look at first.

The structure, from top to bottom

A multi-step income statement reads like a waterfall. You start with sales and subtract costs in layers; each layer reveals a different kind of profit:

  Revenue (net sales)
− Cost of goods sold (COGS)
= GROSS PROFIT
− Operating expenses (wages, rent, marketing, depreciation…)
= OPERATING INCOME (EBIT)
+ Other income − Other expenses (interest)
= INCOME BEFORE TAXES
− Income tax expense (C corporations)
= NET INCOME

What each level tells you

• Gross profit: whether your product sells for more than it costs to make or buy. If you're losing money here, the problem is price or cost, not overhead.
• Operating income: whether the business, with all its structure (rent, staff, marketing), is profitable. It's the cleanest measure of operating health.
• Income before taxes: adds the effect of how you're financed. A healthy business can slip into a loss if it carries expensive debt.
• Net income: what's left for the owners to reinvest or take out.

Net sales, and single-step vs. multi-step

The top line is usually net sales: gross sales minus customer returns, refunds and discounts. If Brightside rings up $18,400 but refunds $150 of remade drinks and gives $250 of loyalty discounts, its net sales are $18,000. Tracking returns and discounts separately, instead of netting them silently, shows you how much revenue leaks away.

You may also run into the single-step format, which lists all revenues, then all expenses, and subtracts once. It's simpler, but it hides gross profit and operating income, the two numbers that tell you the most. Lenders and analysts prefer the multi-step format, and so should you.

Where do taxes go?

It depends on the legal structure. A C corporation pays federal income tax itself (a flat 21%, plus any state tax), so its P&L shows an income tax expense line. Sole proprietorships, partnerships, most LLCs and S corporations are pass-through entities: the business generally pays no federal income tax, and the profit flows to the owners' personal returns. Their P&L usually ends at net income before any income tax. Brightside, a single-member LLC, works this way. Lesson 13 covers the details.

Brightside's income statement

Using the revenue and expense accounts from the trial balance in lesson 5:

(The bank loan arrived on the last business day of the month, so no meaningful interest accrued yet. From next month on, about $50 of interest a month will appear.)

Reading it like an analyst

• A 72.2% gross margin is healthy for a coffee shop: beans and milk are cheap compared with the price of a latte.
• The pressure is below gross profit. Wages and rent eat 58.3% of sales, and they don't shrink in a slow month.
• The $2,300 profit doesn't pay Maya anything. As an LLC owner she isn't on payroll; she lives on draws. If she needs $4,000 a month to cover her own bills, Brightside isn't yet earning enough to replace a salary. Always ask "profit after a fair wage for the owner?" when judging a small business.
• The obvious levers: sell more with the same staff and space (more customers per hour, a higher average ticket) or bring down rent and labor as a share of sales.

Fixed costs, variable costs and the break-even point

For decisions, sort costs by how they behave:

• Variable costs rise and fall with sales: the beans and cup in every latte, card processing fees, sales commissions.
• Fixed costs stay the same whether you sell a lot or a little, at least within a range: rent, salaried staff, insurance, depreciation.

The contribution margin is what each sale leaves after variable costs. For Brightside, treating all wages as fixed, it's $13,000 ÷ $18,000 = 72.2% of sales. The break-even point is the sales level where profit is exactly zero:

Break-even sales = Fixed costs ÷ Contribution margin ratio
                 = ($3,500 + $7,000 + $200) ÷ 0.7222
                 = $10,700 ÷ 0.7222 ≈ $14,815 per month

Brightside sold $18,000, about 21% above break-even. Its margin of safety, how far sales can fall before it loses money, is ($18,000 − $14,815) ÷ $18,000 ≈ 17.7%. Every dollar above break-even adds about 72 cents of profit, which is why profit moves much faster than sales:

A 22% increase in sales, from $18,000 to $22,000, more than doubles operating income. That's operating leverage: when most costs are fixed, growth is very profitable and a slump is very painful.

The income statement is not a cash report

This is where many owners get tripped up. The income statement follows the accrual basis:

• A sale on credit counts as revenue even if you haven't been paid.
• Depreciation is an expense even though no cash leaves.
• Inventory you buy for next month isn't this month's expense.
• The principal on a loan payment never appears; only the interest does.
• Owner's draws don't appear at all.

So you can be profitable and unable to make payroll, or flush with cash from a loan while losing money. The cash flow statement, in lesson 10, untangles this.

Sales revenue                22,000   100.0%
(−) Cost of goods sold       (6,200)   28.2%
Gross profit                 15,800    71.8%
(−) Rent                     (3,500)
(−) Wages                    (7,800)
(−) Advertising                (250)
(−) Depreciation               (200)
Operating income              4,050    18.4%
(−) Interest expense            (50)
Net income                    4,000    18.2%

Summary

• Sales − COGS = gross profit; − operating expenses = operating income; ± interest and other items, − income tax (C corps) = net income.
• Pass-through businesses like LLCs usually show no income tax on their P&L; the owners pay it personally.
• Showing each line as a % of sales (vertical analysis) makes months and companies comparable.
• Break-even sales = fixed costs ÷ contribution margin ratio.
• Profit is not cash, and a small business's profit should be judged after a fair wage for the owner.
