What it means
In accounting, income is what remains once the expenses of generating it are taken away. Revenue is the top line, the total value of goods and services sold, while income is a result that sits underneath costs.
The distinction matters because a company can grow revenue quickly and still report falling income. The income statement steps down through several income figures rather than showing just one.
Gross income deducts only the direct cost of producing what was sold, operating income also deducts the running costs of the business such as salaries and rent, and net income deducts interest and tax as well. Each level answers a different question about where the money went.
Income matters commercially because it is the number that funds everything discretionary. Dividends, bonuses, reinvestment and debt repayment all ultimately come out of income rather than out of revenue.
Lenders and investors therefore track income trends far more closely than they track sales growth alone. Income is an accounting measure rather than a cash measure, and this nuance catches people out regularly.
A business can report healthy income while its bank balance falls, because a sale made on credit counts as income before the customer actually pays. That is why the cash flow statement sits alongside the income statement rather than replacing it.
Personal and tax contexts use the word differently again. For an individual, income normally means gross earnings before deductions, while for a tax authority it means taxable income after allowable reliefs.
When reading any document, check which definition is being used rather than assuming.
In practice
Real-world examples.
Example
A software firm grows revenue from $5,000,000 to $6,500,000, a rise of 30%, and the sales team celebrates. Net income, however, falls from $700,000 to $450,000 because the company hired 14 engineers to support the growth. The board asks for a plan to convert revenue growth into income growth within two years.
Example
A restaurant takes $120,000 of revenue in a busy month. Food and wage costs come to $84,000 and fixed costs such as rent, insurance and loan repayments come to $30,000, leaving income of $6,000. The owner realises that a single quiet month would wipe out the margin entirely.
Example
A freelance consultant invoices $180,000 across the year and incurs $45,000 of travel, software and professional costs. Her income is $135,000, and it is that figure, not the $180,000, that her tax bill and her mortgage application are based on. She keeps the two numbers clearly separate in her records.
Formula
Calculation
Income (net) = Revenue - All expenses, calculated in stages down the income statement.
A regional coffee roaster records revenue of $800,000 for the year. Cost of goods sold is $340,000, so gross income is $800,000 - $340,000 = $460,000. Operating expenses of wages, rent, marketing and insurance total $220,000, so operating income is $460,000 - $220,000 = $240,000. Interest on a bank loan is $20,000 and income tax is $40,000, so net income is $240,000 - $20,000 - $40,000 = $180,000. Checking the same result the short way: total expenses are $340,000 + $220,000 + $20,000 + $40,000 = $620,000, and $800,000 - $620,000 = $180,000. The net income margin is $180,000 / $800,000 = 22.5%, meaning the business keeps 22.5 cents of every dollar it sells.Case study
Seen in the real world.
Larkspur Garden Centres is an illustrative, entirely fictional chain of three garden centres. Its revenue rose from $3,600,000 to $4,200,000 after an aggressive discounting campaign, but net income fell from $360,000 to $210,000. The reason showed up in the gross margin, which slipped from 45% to 39%: gross profit was $3,600,000 x 45% = $1,620,000 in the first year and $4,200,000 x 39% = $1,638,000 in the second, an increase of only $18,000. Meanwhile all other costs rose by $168,000 as the business added staff and delivery vans to serve the extra customers.
The finance director made the point in one sentence at the board meeting: the campaign bought $600,000 of extra revenue for $150,000 of lost income. Management reversed discounts on the top-selling plant lines, kept the improved delivery service, and the following year reported income of $340,000 on revenue of $4,000,000, a margin of 8.5%. The lesson stuck, and every promotion after that was modelled on income rather than on sales volume.
Watch out
Common mistakes.
- Treating income and revenue as the same thing, which makes a loss-making business look successful because its sales are large.
- Assuming income means cash in the bank, when income can include sales invoiced but not yet paid and exclude cash spent on equipment.
- Comparing the income of two businesses without checking whether both figures are before or after tax and interest.
Questions
People also ask.
Is income the same as profit?
In business accounting, yes, the two words are used interchangeably, though "income" is more common in the United States and "profit" more common in the United Kingdom.
Which income figure should I quote to a lender?
Lenders normally want operating income or income before interest, tax, depreciation and amortisation, because it shows what the business generates to service debt.
Can a business have positive income and still run out of money?
Yes, and it is a common cause of failure, because income can be tied up in unpaid invoices, stock and equipment rather than sitting in the bank.
