Paycheck / Salary Calculator

How This Calculator Works

Take-home pay is your salary minus federal income tax, FICA payroll taxes (Social Security and Medicare), and any pre-tax deductions, divided across your pay periods. Enter your annual salary, how often you’re paid, your filing status, and any pre-tax retirement contributions (like a traditional 401(k)), and this calculator estimates that take-home pay per paycheck.

This estimate is federal taxes only. State and local income tax vary enormously by state (nine states have no state income tax at all), so this calculator deliberately doesn’t guess at a single number that would be wrong for most readers — add your own state’s rate separately for a fuller picture.

The Formula

Federal income tax uses the standard marginal bracket method: each slice of your taxable income is taxed at its own bracket’s rate, not your whole income at the top rate you reach. Your taxable income is:

$$\text{Taxable Income} = \vA{\text{Salary}} - \vB{\text{Pre-Tax Contributions}} - \vC{\text{Standard Deduction}}$$

where $\vC{\text{Standard Deduction}}$ depends on your filing status (tax year 2026):

FICA payroll tax is separate from income tax and applies to your $\vA{\text{Salary}}$ (gross wages — pre-tax retirement contributions don’t reduce it):

• Social Security: 6.2%, up to the 2026 wage base of $184,500.
• Medicare: 1.45%, with no wage cap, plus an Additional Medicare Tax of 0.9% on wages above $200,000.

Worked Example

A single filer earning $\vA{\$75{,}000\text{/year}}$, paid biweekly, contributing $\vB{\$5{,}000\text{/year}}$ to a traditional 401(k):

1. Taxable income: $\vA{75{,}000} - \vB{5{,}000} - \vC{16{,}100} = 53{,}900$ dollars.
2. Federal tax (marginal brackets): $1{,}192.50 + 4{,}386.00 + 1{,}193.50 = 6{,}772$ dollars.
3. FICA tax: Social Security is $\vA{75{,}000} \times 6.2\% = 4{,}650$, and Medicare is $\vA{75{,}000} \times 1.45\% = 1{,}087.50$ — a combined $5,737.50.
4. Net pay for the year: $\vA{75{,}000} - \vB{5{,}000} - 6{,}772 - 5{,}737.50 = 57{,}490.50$ dollars.
5. Net pay per paycheck (26 paychecks/year): $2,211.17.

Common Mistakes

• Confusing withholding with actual tax liability. What’s withheld from each paycheck is an estimate the employer sends the IRS on your behalf — your real tax bill is settled at filing time and can come out higher or lower depending on your W-4 elections and other income.
• Forgetting pre-tax deductions reduce taxable income, not just take-home pay. A traditional 401(k) contribution, for example, lowers the income tax is calculated on — it’s not simply money set aside after tax like a savings transfer would be.
• Assuming every state taxes income the same way (or at all). State income tax varies widely and several states charge none at all — check your own state’s rules if this estimate doesn’t match your actual paycheck.
• Mixing up gross pay per paycheck with annual salary. Entering an annual salary into a per-paycheck field (or vice versa) silently produces a wildly wrong result — double-check which one the field is asking for.
