Tax Withholding Calculator

About this calculator

In a typical U.S.-style payroll system, employers do not hand employees their full annual salary in one lump sum — they withhold an estimated portion of income tax from each paycheck and remit it to tax authorities throughout the year, based on the employee's W-4 elections and an estimated effective tax rate. The per-paycheck amount follows simply from (annual gross pay ÷ pay periods) × effective tax rate.

The number of pay periods matters as much as the rate: the same annual salary withholds a different amount per check depending on whether it's paid weekly (52 periods), biweekly (26), semi-monthly (24) or monthly (12). This estimate is a simplified planning tool — actual withholding also depends on filing status, additional withholding elections, pre-tax deductions and bracket-based marginal rates rather than one flat effective rate — but it gives a quick sanity check on whether take-home pay lines up with expectations.
