How much of my paycheck goes to taxes?

For most workers, 20-35% of gross pay goes to federal taxes and FICA. At $75,000 salary (single), expect about 12% federal income tax and 7.65% FICA, totaling roughly 20%. Higher earners pay more due to progressive tax brackets. This doesn't include state taxes.

What is FICA and why is it taken from my paycheck?

FICA stands for Federal Insurance Contributions Act. It funds Social Security (6.2% on income up to $176,100 in 2025) and Medicare (1.45% on all income, plus 0.9% additional Medicare tax on income above $200,000 for single filers). Your employer pays a matching amount.

How does pay frequency affect my paycheck?

Pay frequency doesn't change your annual net pay — it only changes how it's divided. Biweekly (26 paychecks) means smaller checks than semi-monthly (24 paychecks), but you get two extra checks per year. Weekly gives the smallest individual checks but most frequent pay.

How does a 401(k) contribution affect my paycheck?

Traditional 401(k) contributions are pre-tax — they reduce your taxable income, so you pay less federal income tax. A $500/month 401(k) contribution doesn't reduce your paycheck by $500; it reduces it by roughly $380-$420 because of the tax savings.

The Formula

Your paycheck is your gross pay minus federal income tax, Social Security, and Medicare — divided by the number of pay periods in the year.

Federal income tax

The US uses progressive tax brackets. Each bracket applies only to the income within that range, so you never lose money by earning more.

FICA taxes

Social Security = Gross Income × 6.2% (on first $176,100)
Medicare = Gross Income × 1.45% (no cap)
Total FICA = Social Security + Medicare

Per-paycheck calculation

Annual Net = Gross Income − Federal Tax − FICA − Pre-tax Deductions

Per Paycheck = Annual Net ÷ Number of Pay Periods

Example

David — $75K salary, paid biweekly

David earns $75,000 per year, is paid biweekly (26 paychecks), and files as single with no pre-tax deductions.

Gross per paycheck~$2,885

Federal income tax~$385

Social Security (6.2%)~$179

Medicare (1.45%)~$42

Total FICA~$221

Net paycheck~$2,279

David keeps about 79% of each paycheck. His federal tax per check is relatively low because the first $15,750 of income is shielded by the standard deduction, and the first brackets are taxed at only 10% and 12%.

FAQ

Why is so much taken out of my paycheck? ▼

Your paycheck is reduced by federal income tax and FICA (Social Security at 6.2% and Medicare at 1.45%). Together, FICA alone takes 7.65% off the top. Then federal income tax is withheld based on your filing status and the IRS tax brackets. If you also have state income tax, health insurance, or retirement contributions, the deductions add up fast. The calculator shows exactly where every dollar goes.

What's the difference between biweekly and semi-monthly pay? ▼

Biweekly means you're paid every two weeks — that's 26 paychecks per year (and occasionally 27). Semi-monthly means you're paid twice a month on fixed dates (like the 1st and 15th) — that's exactly 24 paychecks per year. Biweekly checks are slightly smaller because the same annual salary is spread over more pay periods, but your total annual pay is the same either way.

How does a 401(k) affect my paycheck? ▼

Traditional 401(k) contributions come out of your paycheck before federal income tax is calculated. That means contributing reduces your taxable income and lowers the tax withheld from each check. For example, if you contribute $500 per paycheck, your taxable income drops by $500, which could save you $110–$160 in federal tax depending on your bracket. Your check is smaller, but not by the full $500. Use "More options" to see the exact impact.

How is overtime taxed? ▼

Overtime is taxed at the same rates as regular income — there's no special "overtime tax rate." However, overtime pay can push your paycheck into a higher withholding bracket for that period, making it look like overtime is taxed more. Your actual tax rate is determined by your total annual income. If too much was withheld, you'll get it back as a refund when you file your tax return.
