Free Payroll Deduction Calculator

A payroll deduction calculator estimates how much pay remains after taxes, benefits, retirement contributions, and other deductions are subtracted from gross pay.

Use it to model paycheck deductions before adjusting benefits, retirement savings, withholding rates, or caregiver payroll settings.

Payroll deduction inputs

Start with gross pay for one paycheck, then add common payroll deductions. The tax rates are planning assumptions, not a formal payroll calculation.

Formula

Take-home pay = gross pay - pre-tax deductions - estimated tax withholding - post-tax deductions. Social Security is estimated at 6.2 percent and Medicare at 1.45 percent of gross pay.

Payroll deduction FAQ

What is a payroll deduction calculator?

A payroll deduction calculator estimates paycheck deductions such as taxes, benefits, retirement savings, and post-tax deductions so you can approximate take-home pay.

Are payroll deductions calculated before or after taxes?

Some deductions are pre-tax and reduce taxable wages, while others are post-tax and come out after tax withholding. Benefit premiums and retirement contributions are common pre-tax examples.

Does this calculator include Social Security and Medicare?

Yes. It estimates Social Security at 6.2 percent and Medicare at 1.45 percent of gross pay for planning purposes.

Why is my real paycheck different from this estimate?

Actual payroll depends on filing status, W-4 settings, state rules, local taxes, wage bases, benefit plan rules, and payroll system rounding.

Can household employers use this calculator?

Yes. Families can use it to model caregiver paycheck deductions before confirming exact payroll settings with their household payroll provider.
