Take-Home Pay After Tax Calculator

Find out what actually lands in your bank account each pay period.

How it is calculated

One flat tax rate is applied after pre-tax deductions are removed. taxable = gross − pretax_deductions, tax = taxable × tax_rate ÷ 100 and net_pay = gross − pretax_deductions − tax − other_deductions. The take-home percentage is net_pay ÷ gross × 100. Use the same pay period for every field (all monthly or all yearly). The tax rate is a single percentage between 0 and 100, so it does not model progressive brackets, social contributions or credits, which vary by country. Other (post-tax) deductions come off after tax and do not reduce taxable income. All four fields are needed, so enter 0 for a deduction you do not have. No result appears when the two deductions together exceed gross pay, or when tax plus deductions would push net pay below zero.

Worked example

Gross pay is $5,000 per month, the flat tax rate is 22%, pre-tax deductions are $300 and post-tax deductions are $150. Taxable pay: 5,000 − 300 = 4,700. Tax: 4,700 × 22% = $1,034.00. Net pay: 5,000 − 300 − 1,034 − 150 = $3,516.00. Total deductions (not counting tax): 300 + 150 = $450.00. Take-home share of gross: 3,516 ÷ 5,000 = 70.32%.

Common mistakes

  • Using your top bracket rate as the flat rate. A flat rate applies to all taxable pay, so a marginal rate overstates the tax; use an average (effective) rate instead.
  • Putting a deduction in the wrong box. Pre-tax items such as retirement or some insurance reduce taxable pay, while post-tax items do not, which changes the tax by the rate times the amount.
  • Typing the rate as a decimal (0.22) instead of 22. The tool accepts it, but tax falls to $10.34 and take-home jumps to 90.79%.
  • Mixing periods, such as annual gross with monthly deductions. The result then makes no sense; keep one period.
  • Leaving a deduction box empty. Each needs a number, 0 if none, otherwise no result is shown.

About this calculator

This calculator works out your net take-home pay — what actually lands in your bank account each pay period — starting from your gross pay and working through a flat income tax rate along with any pre-tax deductions (like traditional 401(k) or retirement contributions and some health insurance premiums, which lower the income your tax is calculated on) and post-tax deductions (like Roth retirement contributions or wage garnishments, which come out after tax is already applied).

The order matters: pre-tax deductions are subtracted from gross pay before the tax rate is applied, shrinking your taxable income and therefore your tax bill, while post-tax deductions are subtracted only after tax has already been calculated on the remaining amount.

Employees use this to sanity-check a paycheck or compare take-home pay across job offers with different salaries and benefits, and it's a common quick-estimate tool alongside more detailed payroll systems that account for progressive tax brackets and jurisdiction-specific withholding.
