Gross vs. Net Pay: Understanding Your Paycheck

Your salary and your paycheck are two different numbers, and the gap between them surprises almost everyone. Gross pay is what you're offered; net pay — take-home pay — is what actually lands in your account after taxes and deductions. Understanding the difference is the foundation of every budget.

Gross pay: the headline number

Gross pay is your full salary or hourly earnings before anything is withheld — the figure in your offer letter and the basis lenders use for debt-to-income ratios. It's real, but you never actually receive all of it, which is why budgeting against gross is the most common budgeting mistake.

What comes out on the way to net

Several deductions stand between gross and net, in roughly this order:

• Pre-tax deductions: 401(k) contributions, HSA, and often health-insurance premiums — these lower your taxable income.
• Federal income tax: withheld based on your W-4 and tax bracket.
• FICA: 6.2% for Social Security (up to the annual wage cap) plus 1.45% for Medicare — a flat 7.65% most workers always pay.
• State and local income tax: varies from zero (in states like Texas and Florida) to over 10% at the top in some states.

A worked example

Take a single filer earning $75,000 in 2026, taking the standard deduction, in a state with no income tax. The standard deduction of $16,100 leaves $58,900 of taxable income, which produces $7,670 of federal tax. FICA takes a flat 7.65% of the full salary, or $5,738.

Net pay is therefore about $61,593 — roughly 82% of gross, or $5,133 a month against a headline of $6,250. Add a state income tax and the share falls further; in the highest-tax states it can reach the low seventies.

Marginal and effective rates are not the same

That filer sits in the 22% bracket, and almost everyone reads that as “22% of my income goes to federal tax”. It does not. Brackets are marginal: the 22% applies only to the income above the bracket threshold, while the dollars below it are taxed at 10% and 12%. Total federal tax of $7,670 on $75,000 is an effective rate of about 10.2%.

The distinction has a practical consequence people act on wrongly: a raise that moves you into a higher bracket never reduces your take-home pay, because only the portion above the threshold is taxed at the new rate. Turning down income to “stay in a lower bracket” is always a mistake.

Pre-tax deductions cost less than they look

Money routed to a 401(k) or HSA before tax reduces the income you are taxed on, so the contribution costs less than its face value. For that same filer, a $7,500 pre-tax contribution cuts federal tax by $1,650 — so $7,500 lands in the retirement account at a real cost of $5,850 in take-home pay.

This is why contribution increases feel smaller in the paycheck than on paper, and it is the strongest practical argument for raising the rate with each pay rise: a one-point increase is partly funded by the tax you no longer pay.

The deductions people forget

Tax is only part of the gap, and the rest catches people out when they compare two job offers. Health insurance premiums are usually the largest non-tax deduction and vary enormously between employers — a difference of $300 a month between two plans is worth more than a $4,000 difference in salary, and it never appears in the offer letter.

Also sitting between gross and net: dental and vision, HSA or FSA contributions, group life cover, disability insurance, union dues, commuter benefits, and any wage garnishment. Most are pre-tax, which softens their cost, but they still reduce what arrives.

This is why comparing offers on salary alone is unreliable. The comparable figure is take-home pay plus the employer's contributions — the match, the premium the employer covers — which can differ by thousands between two jobs advertising the same number.

Your withholding is a setting, not a fact

The federal tax withheld each pay period is an estimate produced by your W-4, not a bill. Get it wrong in one direction and you owe money in April; wrong in the other and you receive a refund.

A large refund is not a windfall. It is the return of money you lent the government at no interest for up to sixteen months, and it usually means the W-4 needs updating — particularly after a marriage, a second job, or a working spouse, which is where withholding most often goes astray. Adjusting it converts a once-a-year lump into monthly cash flow you can actually use.

Budget on net, qualify on gross

Use net pay for anything you actually spend: rent, the 50/30/20 split, whether a car payment fits. Use gross for the decisions institutions make about you — mortgage debt-to-income ratios, contribution limits, and tax brackets are all defined against gross.

Mixing them is the most common budgeting error, and it always fails in the same direction: a budget built on gross income is short by a fifth or more before the month begins.

Run your own number

Turn a salary into an actual paycheck — federal tax, FICA, state tax and pre-tax deductions broken out — in the take-home pay calculator. See what changing your contribution rate does to the paycheck in the paycheck impact calculator, split the result in the 50/30/20 budget calculator, and check what a raise actually adds in the pay raise calculator.
