What it means
The income statement is a flow statement: it covers a span of time, not a moment. Revenue is what the business earned by selling goods and services during the period; expenses are the costs incurred to earn it.
Under accrual accounting, both are recorded when earned or incurred rather than when cash moves, so the profit shown is a measure of economic performance, not of cash generated. That distinction is why the cash flow statement exists alongside it.
The layers matter. Revenue less cost of sales gives gross profit, which shows whether the basic business of buying, making and selling is sound.
Gross profit less operating expenses (selling, administrative, research, depreciation) gives operating profit, which shows whether the business as a whole is profitable before financing and tax. Operating profit less interest gives profit before tax, and after tax comes net profit, the amount available to owners.
Each layer's margin, expressed as a percentage of revenue, can be tracked over time and compared with competitors, and each moves for different reasons. Presentation varies.
Some companies classify expenses by nature (materials, staff costs, depreciation), others by function (cost of sales, distribution, administration). Companies often add subtotals such as EBITDA that the standards do not define, and separate out exceptional or non-recurring items.
IFRS requires a statement of comprehensive income that adds to net profit certain gains and losses, such as currency translation differences and revaluations, that bypass the income statement. Reading the notes is essential to understand what the headline figures include.
The income statement links to the balance sheet through retained earnings: net profit for the period, less dividends, is the increase in the owners' equity. It links to the cash flow statement through the reconciliation of profit to operating cash flow.
A reader who follows those links can tell whether profit is turning into cash and whether the business is building or consuming its capital.
In practice
Real-world examples.
Example
A retailer's income statement shows revenue of $20 million, cost of sales of $13 million and operating expenses of $6 million, leaving an operating profit of $1 million, a 5% margin typical of the sector.
Example
A software company reports a net loss despite 60% gross margins because it spends more than its gross profit on sales and engineering to grow.
Example
A manufacturer's income statement includes an exceptional charge of $2 million for closing a plant, shown separately so that readers can see underlying profit.
Think of it
“An income statement is like a report card for your business finances. It shows what you earned, what you spent, and whether you came out ahead.
Formula
Calculation
Gross Profit = Revenue minus Cost of Sales
Operating Profit = Gross Profit minus Operating Expenses
Profit Before Tax = Operating Profit minus Finance Costs plus Finance Income
Net Profit = Profit Before Tax minus Income Tax
Worked example. A furniture maker's income statement for the year:
- Revenue: $5,000,000
- Cost of sales (timber, hardware, factory labour, factory overhead): $3,100,000
- Gross profit: $1,900,000 (38.0% gross margin)
- Selling and distribution expenses: $450,000
- Administrative expenses: $620,000
- Depreciation and amortization: $180,000
- Operating profit: $650,000 (13.0% operating margin)
- Interest expense: $90,000
- Profit before tax: $560,000
- Income tax at 25%: $140,000
- Net profit: $420,000 (8.4% net margin)
EBITDA, if the company reports it, = operating profit + depreciation and amortization = $650,000 + $180,000 = $830,000.
Reading the layers: if the prior year showed gross margin of 41% and operating margin of 13%, the business has lost three points of gross margin (input costs or pricing) but held operating margin by cutting overheads. If instead gross margin held at 41% and operating margin fell from 16% to 13%, the problem lies in overhead growth. The same net profit can come from very different stories.Case study
Seen in the real world.
A chain of eight garden centres showed a net profit of $600,000 on $18 million of revenue, and the owners assumed the business was healthy. A new finance director produced an income statement by branch for the first time. Three branches earned operating margins of 12% to 15%.
Three broke even. Two lost money, one of them heavily, and the head office costs allocated to each branch had been hiding the pattern. The losing branches shared a cause: they were in locations with high rent and low footfall, and their gross margins were four points lower than the group's because they discounted to move stock.
The owners closed the worst branch, renegotiated the lease on the other, and redirected the buying and marketing budget towards the three strong performers. Group net profit rose to $1.1 million on revenue that fell 8%, and the finance director's monthly pack now begins with an income statement per branch rather than one for the group.
Watch out
Common mistakes.
- Reading net profit alone. The layers above it explain whether the business model, the cost base or the financing is driving the result.
- Treating profit as cash. Profit is an accrual measure; the cash flow statement shows what actually arrived.
- Accepting adjusted or underlying profit without reading what was excluded. Exceptional items that recur every year are not exceptional.
Questions
People also ask.
What is the difference between the income statement and the balance sheet?
The income statement covers performance over a period. The balance sheet shows position at a date. Profit from the first flows into equity on the second.
What is the difference between gross profit and net profit?
Gross profit is revenue less the direct cost of what was sold. Net profit is what remains after all expenses, interest and tax.
Is the income statement the same as the profit and loss account?
Yes. The terms are interchangeable, and IFRS uses "statement of profit or loss" or "statement of comprehensive income".
