Paycheck Calculator
Estimate take-home pay after taxes and deductions for employees.
Formula
Take-Home Pay = Gross Pay − Federal Tax − State Tax − FICA (7.65%) − Pre-Tax Deductions − Post-Tax Deductions
How to Calculate
To estimate take-home pay, start with gross pay (annual salary divided by pay periods, or hourly rate times hours worked). Then subtract all applicable withholdings in this order: pre-tax deductions (401k contributions, health insurance premiums, HSA/FSA contributions), federal income tax, state income tax, local taxes if applicable, and FICA (Social Security 6.2% and Medicare 1.45%).
Federal income tax withholding is based on your W-4 selections, filing status, and the IRS tax tables. The amount withheld depends on your pay frequency and claimed allowances or adjustments. Most payroll systems use the percentage method from IRS Publication 15-T.
After all taxes, subtract any post-tax deductions like Roth 401k contributions, disability insurance, union dues, or wage garnishments. The remaining amount is your net pay—the actual deposit in your bank account. Remember that pre-tax deductions reduce your taxable income, while post-tax deductions do not.
Worked Example
An employee earns $75,000/year, paid bi-weekly (26 pay periods), single filer.
Gross pay per period: $75,000 / 26 = $2,885 Pre-tax 401k (6%): −$173 Health insurance: −$125 Taxable pay: $2,885 − $173 − $125 = $2,587
Federal income tax (estimated): −$290 State income tax (5%): −$129 Social Security (6.2%): −$179 Medicare (1.45%): −$42
Net pay per paycheck: $2,587 − $290 − $129 − $179 − $42 = $1,947 Annual take-home: $1,947 × 26 = $50,622 (67.5% of gross salary)
Why It Matters
Understanding your paycheck breakdown helps you make informed decisions about benefits enrollment, retirement contributions, and tax planning. Many employees are surprised by how much taxes and deductions reduce their gross pay—typically 25–35%. This knowledge is crucial for budgeting, negotiating salary, and optimizing your tax situation through pre-tax benefit elections.
Practical Tips
- ✓Increase 401k contributions to reduce taxable income—every dollar contributed pre-tax saves you your marginal tax rate.
- ✓Review your W-4 annually, especially after major life events like marriage, home purchase, or a child.
- ✓Maximize employer 401k match—not doing so is leaving free money on the table.
- ✓Use an HSA if eligible—it offers triple tax benefits (tax-free contributions, growth, and qualified withdrawals).
