Free Paycheck Stub Calculator
Estimate gross pay, payroll deductions, and net pay for hourly or salary employees. This is an educational estimate, not tax or payroll advice.
What is a paycheck stub calculator?
A paycheck stub calculator is a quick way to estimate what a pay statement might look like before payroll is finalized. You can enter wages, taxes, and deductions to get a clean estimate of gross pay, taxable wages, and take-home pay. It is especially useful when comparing job offers, checking a raise, planning overtime, or reviewing a recent payroll change.
Think of this tool as a planning assistant. It helps you understand where your money goes each pay period and can make personal budgeting much easier.
How this paycheck estimator works
1) Gross pay calculation
Gross pay is the starting point. For hourly workers, gross pay is based on regular hours plus overtime hours. For salaried workers, gross pay is estimated by dividing annual salary by pay periods in a year.
- Hourly: (Hourly Rate × Regular Hours) + (Hourly Rate × Overtime Multiplier × Overtime Hours)
- Salary: Annual Salary ÷ Number of Pay Periods
2) Pre-tax deductions
Pre-tax deductions come out before taxes are calculated. Common examples include health insurance, commuter plans, and retirement contributions. Since taxes are calculated after these deductions, they can reduce taxable wages.
3) Tax estimates
The calculator then applies your federal and state tax percentages to taxable wages. It can also include Social Security and Medicare, plus any additional withholding amount you choose to enter.
4) Post-tax deductions and net pay
Post-tax deductions are removed after taxes are calculated. Finally, net pay is estimated as:
- Net Pay = Gross Pay − Pre-tax Deductions − Taxes − Post-tax Deductions
Common paycheck stub items explained
- Gross Pay: Total earnings before deductions and taxes.
- Taxable Wages: Earnings that remain after pre-tax deductions.
- Federal Withholding: Estimated federal income tax withheld from pay.
- State Withholding: Estimated state income tax withheld (if applicable).
- FICA Taxes: Social Security and Medicare payroll taxes.
- Net Pay: What is left after all deductions and taxes.
Tips for more accurate paycheck estimates
- Use your real pay frequency (weekly, biweekly, semi-monthly, or monthly).
- Enter realistic tax rates based on your current withholding setup.
- Include known pre-tax benefits and post-tax items.
- If your hours vary, run multiple scenarios (low, average, high overtime).
- Compare estimates with your most recent actual pay stub and adjust inputs.

- Evaluating a new job offer or promotion
