How it works
Your take-home paycheck is calculated by subtracting all applicable taxes and pre-tax deductions from your gross annual salary. The calculator applies federal, state, and FICA taxes in sequence, then removes pre-tax deductions that lower your taxable income. The result is your net annual pay—the amount you actually receive.
The formula
Net Pay = (Gross Pay − Pre-tax Deductions) − (Federal Tax % × Taxable Income) − (State Tax % × Taxable Income) − (FICA % × Gross Pay)
Worked example
Let's say you earn $65,000 per year with the following:
- Gross annual pay: $65,000
- Pre-tax deductions: $4,500 (401(k) and health insurance)
- Federal tax rate: 12%
- State tax rate: 5%
- FICA rate: 7.65%
Step 1: Calculate taxable income $65,000 − $4,500 = $60,500
Step 2: Calculate federal tax $60,500 × 0.12 = $7,260
Step 3: Calculate state tax $60,500 × 0.05 = $3,025
Step 4: Calculate FICA (on gross, not reduced by pre-tax deductions) $65,000 × 0.0765 = $4,972.50
Step 5: Sum all deductions $4,500 + $7,260 + $3,025 + $4,972.50 = $19,757.50
Step 6: Calculate net pay $65,000 − $19,757.50 = $45,242.50 per year
Divided across 26 bi-weekly paychecks: $45,242.50 ÷ 26 = $1,740 per paycheck
Common mistakes
Forgetting that FICA applies to gross pay, not taxable income. Social Security and Medicare taxes are calculated on your full salary before pre-tax deductions are subtracted. This calculator applies FICA correctly, but many people mistakenly reduce FICA by pre-tax deductions.
Using inaccurate tax percentages. Federal and state withholding depend on your filing status, number of dependents, and tax credits. If your estimate seems far off from your actual paycheck, review your W-4 form and adjust the percentages accordingly. Your employer's payroll system should show you the exact rates being withheld.
This is an estimate, not professional advice. Actual take-home pay varies based on tax brackets, deductions, credits, and individual circumstances. Consult a tax professional or use the IRS tax withholding estimator for precise calculations.
