How the paycheck calculator works
The calculator annualizes your pay, subtracts pre-tax 401(k) contributions and health premiums, then applies the 2026 standard deduction and federal tax brackets for your filing status to estimate federal income tax. It adds Social Security tax (6.2% on wages up to the 2026 wage base of $184,500), Medicare tax (1.45% on all wages, plus 0.9% on wages above $200,000) and a flat state rate you enter. Each amount is divided by the number of paychecks in a year.
The formula
Take-home pay = gross pay − pre-tax deductions − federal income tax − Social Security − Medicare − state tax. Note that 401(k) contributions reduce income tax but not Social Security and Medicare, while most health premiums paid through a cafeteria plan reduce both.
Example
A single filer earning $60,000 and paid every two weeks, with no state tax or deductions, has about $5,020 in federal income tax, $3,720 in Social Security and $870 in Medicare for the year. That leaves roughly $1,938 per paycheck.
This is an estimate
Actual withholding follows the IRS Publication 15-T tables and your Form W-4, which can include dependents, extra withholding and other adjustments. Many states have progressive brackets, local taxes, or no income tax at all, and this tool uses a single flat state rate. Newer federal deductions, such as those for tips, overtime and seniors, and tax credits are not included. Use it for budgeting, not for filing.
Frequently asked questions
Why is my real paycheck different?
Employers withhold using your W-4 settings and IRS withholding tables, and may deduct items like insurance, HSA or union dues. This tool gives a close estimate based on annual tax.
What is FICA?
FICA is Social Security (6.2%) plus Medicare (1.45%) taken from your wages. Your employer pays a matching amount.
Which states have no income tax on wages?
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming do not tax wage income. Enter 0% for those.
Does a 401(k) contribution lower my taxes?
A traditional 401(k) lowers federal and usually state income tax now. Roth 401(k) contributions do not.
