Free Paycheck Calculator
A free paycheck calculator — see your estimated take-home pay after taxes and payroll deductions from your gross salary.
How the payroll deductions calculator works
It subtracts your pre-tax deductions from gross pay to find taxable wages, applies your income tax rate, adds FICA (7.65% on gross), and leaves your take-home pay for the period.
Worked example: with gross pay per period of $3,000, pay periods per year of 26 and pre-tax deductions per period (401k, health) of $400, the payroll deductions calculator shows take-home pay per period of $1,798.50.
- Pre-tax deductions
- $400.00
- Income tax
- $572.00
- FICA (Social Security + Medicare)
- $229.50
- Net pay
- $1,798.50
The formula
Net pay = gross − pre-tax deductions − (taxable wages × income tax rate) − (gross × 7.65% FICA).

Questions about the payroll deductions calculator
What is FICA?
The combined Social Security (6.2%) and Medicare (1.45%) payroll tax — 7.65% total — withheld from your gross pay. Your employer pays a matching amount.
Why do pre-tax deductions help?
They lower the wages subject to income tax, so they reduce your take-home pay by less than their full amount. Common examples are 401(k) and health-insurance premiums.
Is this exact withholding?
It is an estimate. Real withholding depends on your W-4, filing status and state, but this shows the mechanics of gross-to-net pay.
Is the Payroll Deductions Calculator free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
