Gross-to-Net Salary Calculator
Convert an annual gross salary to net pay after pre-tax deductions, income tax, and payroll tax, with a per-paycheck breakdown.
How to use this tool
- Enter your annual gross salary.
- Add annual pre-tax deductions and your effective income tax rate.
- Confirm the payroll tax rate and number of pay periods per year.
- Read your annual net salary and net pay per period.
Convert your annual salary to take-home pay. Enter gross salary, pre-tax deductions, your effective income and payroll tax rates, and pay frequency to see net pay per year and per paycheck.
Formula
Taxable pay = Gross salary − Pre-tax deductions
Income tax = Taxable pay × Income tax rate
Payroll tax = Gross salary × Payroll tax rate
Net salary = Gross − Pre-tax − Income tax − Payroll tax | Per period = Net ÷ Pay periods
How it works
This calculator turns an annual gross salary into annual and per-paycheck net pay. Pre-tax deductions are removed first because they reduce the income subject to income tax; income tax is then applied to the taxable figure. Payroll tax (the employee share of Social Security and Medicare) is applied to gross wages, since pre-tax retirement contributions still owe payroll tax. The result is divided by your number of pay periods for a per-check figure.
Income tax rates depend on brackets, filing status, and jurisdiction, so the effective income tax rate is an editable input; the US employee payroll rate of 7.65% (6.2% Social Security plus 1.45% Medicare) is the default but can be changed. The model uses a single effective income tax rate rather than full progressive brackets and ignores the Social Security wage cap, so for very high salaries the payroll line is slightly overstated. Use your pay stub's actual effective rates for the closest match.

Worked example
$80,000 gross, $8,000 pre-tax, 18% income, 7.65% payroll, monthly
- Taxable pay = 80,000 − 8,000 = 72,000.
- Income tax = 72,000 × 18% = 12,960.
- Payroll tax = 80,000 × 7.65% = 6,120.
- Total tax = 12,960 + 6,120 = 19,080.
- Net salary = 80,000 − 8,000 − 19,080 = 52,920; per month = 52,920 ÷ 12 = 4,410.
Annual net salary = $52,920.00 ($4,410.00 per period)

- Pay period
- An interval between paychecks; 12 monthly, 24 semi-monthly, or 26 bi-weekly are common.

Frequently asked questions
- Why is payroll tax applied to gross, not taxable, pay?
- Pre-tax retirement contributions reduce income tax but generally still owe Social Security and Medicare tax. So this tool applies payroll tax to gross wages while applying income tax to the lower taxable figure.
- How many pay periods should I enter?
- Use 12 for monthly pay, 24 for semi-monthly (twice a month), or 26 for bi-weekly (every two weeks). The annual net is the same; only the per-period amount changes.
- Is the single income tax rate accurate?
- It is an approximation. Real income tax is progressive, so use your effective rate (total income tax divided by taxable pay) rather than your top bracket for a realistic result.
