What Is Net Income? Definition and How to Calculate It
By Markets & Investing DeskUpdated Nov 10, 2026
Definition
Net income is what remains of total revenue after all expenses, interest and taxes are subtracted. For a person, it is take-home pay after taxes and payroll deductions.
Key takeaways
- Net income equals revenue minus all expenses, interest and taxes. It is an after-tax figure.
- It appears last on the income statement and is the basis for earnings per share (EPS).
- A negative result is a net loss.
- Net income is an accrual accounting measure, so it can differ sharply from the cash a business actually collects.
- For a person, net income is gross pay minus taxes and deductions such as 401(k) contributions.
Net income is the amount left from total revenue after every expense for a period has been subtracted: cost of goods sold, operating expenses, interest, taxes and any other losses, plus any other gains. Also called net earnings or net profit, it is the final line of a company’s income statement, which is why it is known as the “bottom line.” For an individual, net income means pay after taxes and payroll deductions, the take-home figure on a pay stub.
How Net Income Works
A company records revenue when it earns it and records expenses when they are incurred, and the income statement subtracts those expenses in layers. Each layer produces a different profit measure, and net income is the one left after the last subtraction.
Calculating Net Income
The basic formula is:
Net income = Total revenue − Total expenses
Written out in the order an income statement uses:
- Revenue − cost of goods sold (COGS) = gross profit
- Gross profit − operating expenses (wages, rent, marketing, depreciation) = operating income
- Operating income − interest expense ± other gains and losses = pretax income
- Pretax income − income tax expense = net income
Under U.S. GAAP, net income is the figure reported after these items. Companies often publish “adjusted” earnings that add back items such as restructuring charges or stock-based compensation. Those adjusted figures, including the “net income after addbacks” used when small businesses are valued for sale, are not GAAP net income and should be read separately from it.
Interpreting Net Income
A raw net income figure says little on its own because company size varies so much. Analysts usually convert it into ratios:
- Net profit margin = Net income ÷ Revenue
- Earnings per share = (Net income − Preferred dividends) ÷ Weighted average shares outstanding
- Return on equity = Net income ÷ Shareholders’ equity
The price-to-earnings ratio also uses net income, through EPS. Comparing these ratios across periods shows whether profitability is improving relative to sales and capital.
Why Is Net Income Important?
Net income connects all three main financial statements. On the income statement it is the final result. On the balance sheet, net income for the period (minus any dividends paid) is added to retained earnings within shareholders’ equity. On the cash flow statement, the indirect method starts with net income and then adjusts it for non-cash items and working capital changes to reach operating cash flow.
For shareholders, net income measures what the business earned on their behalf after creditors and tax authorities were paid. Under IFRS reporting, the figure is labeled profit for the period attributable to the owners of the parent, a wording common in UK accounts. Lenders, management and boards use it to judge whether the company can fund dividends, debt payments and growth from its own earnings.
Example of Net Income
Hypothetical company, one fiscal year:
| Line item | Amount |
|---|---|
| Revenue | $500,000 |
| COGS | −$200,000 |
| Gross profit | $300,000 |
| Operating expenses | −$180,000 |
| Operating income | $120,000 |
| Interest expense | −$20,000 |
| Pretax income | $100,000 |
| Income tax (assumed 21% rate) | −$21,000 |
| Net income | $79,000 |
Net profit margin is $79,000 ÷ $500,000 = 15.8%. If the company has 100,000 shares outstanding and no preferred stock, EPS is $0.79.
Hypothetical employee, one month: gross pay of $5,000, minus $600 of income tax withholding, $382.50 of Social Security and Medicare tax (7.65%), $250 of 401(k) contributions and $150 of health insurance premiums, leaves net monthly income of $3,617.50. Annual net income is the same calculation over a full year.
On a U.S. individual return, Form 1040 reports gross income, adjusted gross income (AGI) and taxable income, but it has no net income line. AGI is gross income minus specific adjustments, such as student loan interest, and it is calculated before income tax, so it is not the same as net income.
Limitations of Net Income
- It is not cash. Sales on credit count as revenue before payment arrives, and depreciation reduces net income without any cash leaving. A profitable company can still run short of cash, which is why investors also look at free cash flow.
- One-time items distort it. Selling a building, settling a lawsuit or booking an impairment can swing net income in a single period without saying anything about ongoing operations.
- It can be managed. Aggressive revenue recognition, capitalizing costs that should be expensed, or shifting expenses between periods can inflate the figure. Reading the notes and the auditor’s report helps judge the quality of earnings.
- Comparisons are uneven. Interest and tax depend on how a company is financed and where it operates, so two businesses with identical operations can report different net income. Measures such as EBITDA remove those items for comparison, at the cost of ignoring real expenses.
Net Income vs. Related Terms
- Gross income or gross profit: revenue minus only COGS for a business, or total pay before deductions for a person. Net income comes after every other subtraction.
- Operating income: profit from core operations before interest and taxes.
- Pretax income: net income before income tax expense is subtracted.
- Revenue: the top line, before any costs.
FAQs
Is net income on the balance sheet?
Not as its own line. The balance sheet is a snapshot at a point in time, while net income measures a period. Net income reaches the balance sheet indirectly by increasing retained earnings, after dividends are deducted.
What is net business income?
For a sole proprietor or small business, net business income is business revenue minus allowable business expenses. In the U.S., self-employed people report this on Schedule C, and the result is the business's profit before the owner's personal income tax, which differs from corporate net income, where income tax has already been subtracted.
Can net income be negative?
Yes. When expenses exceed revenue for the period, the result is a net loss, shown as a negative number or in parentheses. A net loss reduces retained earnings.
The Bottom Line
Investors, lenders and managers rely on net income to see what a business earned after creditors and taxes were paid, and individuals use it to know their actual take-home pay. Because it is an accrual figure that one-time items or aggressive accounting can shift, read it alongside cash flow, profit margins and the notes before judging a company's health.
