Net income is the amount of earnings left after all required and elected deductions are subtracted from gross income. For an employee, that means gross pay minus income tax withholding, payroll taxes, and any benefit deductions such as health premiums or 401(k) contributions — the figure commonly called take-home pay. In a business context, net income is the profit remaining after every expense, including taxes, has been paid.
Net Income
Net income is what remains of your earnings after taxes and other deductions come out — your take-home pay. For a business, it means profit: revenue minus all expenses and taxes.

Quick Summary
- Net income is gross pay minus taxes and deductions — the amount that actually lands in your bank account.
- Typical paycheck deductions include federal and state income tax withholding, Social Security and Medicare (FICA) taxes, health insurance premiums, and retirement contributions.
- Budgets built on gross income overstate what you can spend; net income is the honest starting point for a spending plan.
- For a business, net income is the bottom line — revenue minus all operating expenses, interest, and taxes.
Definition
Advanced Explanation
A paycheck shrinks in layers, and knowing what each layer does helps you read a pay stub intelligently. Income tax withholding — federal, and state where applicable — is an estimate of the tax you'll owe, controlled by the Form W-4 you file with your employer; it settles up when you file your tax return. Payroll taxes are separate and fixed: the employee share of FICA is 6.2% for Social Security (on wages up to the annual wage base — $184,500 for 2026) plus 1.45% for Medicare on all wages, with an additional 0.9% Medicare tax on wages above certain high-income thresholds.
Then come the deductions you choose. Pre-tax items — traditional 401(k) deferrals, health premiums, HSA and FSA contributions — reduce the income your withholding is calculated on, so they cost you less than their face amount. That creates a subtle trap when judging your finances by take-home pay alone: someone saving aggressively in a 401(k) has a lower net income but a stronger financial position. Net income also differs from taxable income (the figure your tax bill is actually computed on, after deductions) and from adjusted gross income — three different numbers that get conflated constantly.
Used in a Sentence
“My salary is $80,000, but after taxes, insurance, and my 401(k) contribution, my net income is closer to $55,000 — so that's the number I budget from.”
How It Works
Start with gross pay, subtract pre-tax deductions, then payroll taxes, then income tax withholding, then any after-tax deductions. What's left is net income.
A hypothetical example: Jordan earns $80,000 a year, or about $6,667 per month gross. Each month, $300 goes to a pre-tax health premium and $400 (6%) to a traditional 401(k). FICA taxes of roughly $487 come out (7.65% of the FICA-taxable wages), and combined federal and state income tax withholding runs about $880 based on Jordan's W-4. Net income: $6,667 − $300 − $400 − $487 − $880 = about $4,600 per month. The withholding figures here are illustrative — actual amounts depend on your W-4 entries, state, and filing situation.
Pros and Cons
Pros (of budgeting from net income)
- It reflects money you can actually spend, so your budget matches reality.
- It forces you to see the true cost of taxes and benefits rather than mentally spending your gross salary.
- It updates automatically when your withholding or benefits change.
Cons
- It understates your total savings effort — pre-tax 401(k) and HSA contributions are savings, even though they never hit your bank account.
- Withholding is only an estimate; if your W-4 is set wrong, your "net income" is quietly borrowing from (or lending to) the IRS until you file.
- Comparing net income across jobs can mislead, since benefit costs and state taxes differ.
People Also Asked
Answers to the most frequently asked questions.
What is the difference between gross income and net income?
Gross income is everything you earn before anything comes out — the salary in your offer letter. Net income is what remains after taxes, payroll deductions, and benefit costs are subtracted. The gap between the two is commonly 20–35% of gross pay, depending on your tax situation, state, and how much you put toward benefits and retirement.
Is net income the same as taxable income?
No. Net income is a cash-flow figure — what hits your bank account. Taxable income is a tax-return figure: gross income minus specific deductions the tax code allows, such as the standard deduction. You can have a high taxable income and a modest net income at the same time — for example, large Roth 401(k) contributions shrink your take-home pay but don't reduce your taxable income at all.
Does my 401(k) contribution reduce my net income?
Yes — the contribution comes out of your paycheck, so your take-home pay drops. But a traditional 401(k) contribution also reduces your income tax withholding, so your net income falls by less than the contribution amount. That money isn't gone; it's savings you've moved to a retirement account before you could spend it.
What does net income mean for a business?
For a business, net income is profit: total revenue minus all expenses, including cost of goods, overhead, interest, and taxes. It's the "bottom line" on a profit-and-loss statement. Self-employed people should note that their personal spending budget runs on what's left after self-employment tax and income tax — not on the business's gross revenue.
