Quick answer
A $80,000 salary paid biweekly nets about $2,504 per paycheck for a single filer in 2026 with no state income tax and no pre-tax deductions. Federal withholding takes about $337 of each check and payroll tax takes $235. State tax, 401(k) contributions and health insurance reduce it further.
How the Paycheck Calculator works, step by step
Enter your gross salary or hourly wage, how often you are paid, and your filing status. The calculator annualizes your pay, applies the 2026 standard deduction of $16,100 for single filers or $32,200 for joint filers, then runs the federal brackets and divides the result back across your pay periods, so the per-check figure matches your real pay cycle.
Payroll tax is worked out separately from income tax. Social Security takes 6.2% of wages up to the 2026 wage base of $184,500, and Medicare takes 1.45% of all wages with no cap. Earners over $200,000 single or $250,000 joint pay an extra 0.9% Medicare tax on wages above those thresholds. Your employer matches the Social Security and Medicare amounts, but that match never appears on your pay stub.
Pre-tax deductions lower the wages that tax is figured on, but not all of them lower every tax. Enter 401(k) contributions and HSA contributions plus pre-tax health premiums separately: the 401(k) comes off before the federal brackets only, while HSA and health premiums come off before payroll tax too. For 2026 the employee 401(k) deferral limit is $24,500, or $32,500 from age 50. Every dollar deferred at a 22% marginal rate saves 22 cents of federal tax that year.
State income tax is a flat percentage you set yourself, because state systems vary too much for one formula. Enter 0% if you live in a state with no income tax, such as Texas or Florida, or your own effective rate if you know it. The result is a planning estimate, not your state's exact withholding table.
The result is a pay-stub view: gross per check, each deduction line, and net pay per period and per year, plus the share of your salary you keep. Actual withholding also depends on your Form W-4 entries and on any bonuses or overtime in a given period, so treat the figure as an estimate and check it against a real pay stub.
The formula
Federal taxable wages = salary minus 401(k) minus HSA and health premiums. Federal tax = bracket tax on (taxable wages minus the standard deduction). Payroll tax = 6.2% of FICA wages (salary minus HSA and health premiums only) up to $184,500, plus 1.45% of all FICA wages, plus 0.9% above $200,000 single or $250,000 joint. Net pay = salary minus all taxes and deductions.
Worked example — try it on the calculator above
Worked example: $80,000 salary, biweekly pay, single, 2026
A single filer earns $80,000, is paid every two weeks, and has no state tax or pre-tax deductions. Federal tax on $63,900 of taxable income is $8,770. Social Security takes $4,960 and Medicare takes $1,160, for $6,120 of payroll tax. Total tax is $14,890, leaving $65,110 a year, or $2,504.23 per paycheck. Federal withholding is $337.31 per check and payroll tax is $235.38. Adding a 5% state tax would take another $153.85 per check. A $3,000 annual 401(k) contribution would cut federal taxable wages to $77,000, saving about $660 of federal tax and nothing on payroll tax, so net pay would fall by about $2,340 a year while $3,000 went into retirement.
Frequently Asked Questions
How much tax is taken out of a biweekly paycheck?
It depends on your salary, filing status, state and pre-tax deductions. On an $80,000 salary for a single filer with no state tax, about $573 comes out of each biweekly check: $337 of federal tax and $235 of payroll tax. State tax and benefits such as health insurance come out on top of that.
Why does my take-home pay rise late in the year?
Once your year-to-date wages pass the $184,500 Social Security wage base for 2026, the 6.2% Social Security deduction stops for the rest of the year. On a $250,000 salary that adds about $596 to each biweekly check from that point on. Medicare tax has no cap, so it continues all year.
Do 401(k) contributions lower my payroll tax too?
No. Traditional 401(k) contributions lower the wages used for federal income tax, but Social Security and Medicare tax still apply to the full wage, so they save on income tax only. HSA contributions made through payroll are different: they lower both income tax and payroll tax. Roth 401(k) contributions do not lower taxable wages at all, so do not include Roth amounts in either entry.
Is the paycheck estimate the same as my employer's withholding?
Not exactly. Employers use IRS Publication 15-T withholding tables and your Form W-4 entries, which account for multiple jobs and other adjustments. This calculator annualizes your pay and applies the brackets directly, which is close for a single steady job but can differ if your pay varies or you hold more than one job.
