DISCLAIMER
Paycheck Calculator is an independent tool. It is not affiliated with, authorized by, endorsed by, or in any way officially connected with the Internal Revenue Service (IRS), the Social Security Administration (SSA), or any federal, state, or local government agency.
All figures shown are estimates. Your employer's actual payroll calculation is what determines your pay — always check your real pay stub.
WHAT IT DOES
Enter your salary and see your estimated take-home pay: gross, federal income tax, Social Security, Medicare, state tax, city wage tax, 401(k) and HSA/FSA. Salary or hourly; weekly, biweekly, semi-monthly, monthly or annual. All 50 states plus DC.
• Compare — save two scenarios and see them side by side.
• What-If — sliders for a raise, 401(k) percent and a bonus, plus a change-of-state picker, with the delta updating live.
• Sources — every figure is stamped with the document it came from.
Runs on your phone. No account, no subscription. Your income is not uploaded.
