Take-Home Pay Calculator
Your salary isn’t what lands in your account. Enter your pay and your W-4 to see what each paycheck keeps after 2026 federal income tax — withheld the way payroll software does it, by the IRS’s own tables — Social Security and Medicare, your 401(k) and health premiums, and state tax.
To see how your income is taxed bracket by bracket, use the Tax Bracket Calculator. Comparing offers? The Salary to Hourly Calculator puts pay on the same footing, and the Pay Raise Calculator shows what a raise adds before tax. Pre-tax saving lowers this year’s tax: see what it grows to with the 401(k) Calculator and the HSA Calculator.
Married filing separately? The W-4 has you check Single.
Step 3 credits: $0.00 a year — $2,200 a child, $500 for each other dependent.
Health, dental and vision premiums, plus HSA or FSA money taken from your pay (Section 125), skip income tax and Social Security and Medicare. A traditional 401(k) skips income tax only.
One flat rate on your wages after pre-tax deductions — an estimate, since states have their own brackets and some have no income tax. Add a local income tax rate if you pay one.
4(a) is income that isn’t from a job, like interest or dividends. 4(b) is deductions beyond the standard deduction — including the 2025–2028 deductions for tips, overtime, age 65+ and car-loan interest — from the W-4’s Deductions Worksheet.

Federal income tax here is what your employer withholds, by the IRS’s 2026 withholding tables (Publication 15-T) — an estimate, not your tax bill. Your actual tax is settled on your return, from the whole year’s income, deductions and credits, so you may get a refund or owe.
The math, in the open.
gross = salary ÷ paychecks a year (52 · 26 · 24 · 12), to the cent
401(k) = gross × your 401(k) %
income-tax wages = gross − 401(k) − pre-tax benefits
FICA wages = gross − pre-tax benefits
federal = IRS Pub 15-T, Worksheet 1A (annual percentage method):
annual wage = income-tax wages × paychecks + Step 4(a) − Step 4(b) − allowance
tentative = the annual table’s tax on that wage ÷ paychecks
withheld = max(0, tentative − Step 3 credits ÷ paychecks) + Step 4(c)
Social Security = 6.2% × FICA wages, until the year’s FICA wages reach $184,500
Medicare = 1.45% × FICA wages, + 0.9% on the year’s wages over $200,000
state tax = state rate × income-tax wages
take-home = gross − 401(k) − pre-tax benefits
− federal − Social Security − Medicare − state tax- salary

Assumptions & limits
- 2026 federal figures: brackets and standard deductions from the IRS’s annual Revenue Procedure, withholding from Publication 15-T (2026), Social Security at 6.2% up to the $184,500 wage base, Medicare at 1.45%, and the 0.9% Additional Medicare Tax withheld on wages over $200,000.
- The headline is the first paycheck of the year. The full-year figures add up every paycheck, so they include Social Security stopping at the wage base and Additional Medicare starting past $200,000.
- A Form W-4 from 2020 or later. Older forms with withholding allowances use different tables and aren’t modeled.
- A steady salary only: no bonuses or other supplemental pay, no 27th biweekly payday, and no mid-year raise or job change.
- State income tax is one flat rate on the wages federal income tax applies to; real state brackets, deductions and credits differ. Local income taxes (unless you add their rate) and state payroll taxes such as disability or paid-leave insurance aren’t included.
- Gross pay per paycheck is the salary ÷ paychecks, rounded to the cent, so a year of paychecks can differ from the salary by a few cents; 401(k) dollars are rounded to the cent each paycheck.
- Roth 401(k) contributions and other after-tax deductions aren’t modeled — subtract them from the take-home pay shown.
- Withholding is an estimate of what comes out of each paycheck, not your tax bill: the refund or balance due is settled on your return.
