What This Calculator Does
This calculator estimates how much salary you keep after U.S. federal taxes. It applies the standard deduction for the selected filing status, estimates federal income tax using progressive tax brackets, and optionally estimates Social Security and Medicare taxes.
The result is an estimated annual net figure plus monthly, bi-weekly, and weekly after-tax salary. It is designed for fast planning, job comparison, and salary reality checks rather than payroll processing.
Example Calculation
| Input | Example |
|---|---|
| Annual salary | $85,000 |
| Filing status | Single |
| Standard deduction used | $15,000 |
| Taxable income | $70,000 |
| Estimated federal income tax | Calculated progressively across brackets |
| Estimated FICA | 6.2% Social Security up to the wage base plus 1.45% Medicare |
| Output | Estimated annual and per-pay-period after-tax salary |
Formula
Taxable Income = Gross Salary − Standard Deduction
Federal Income Tax = Sum of each tax bracket slice × its tax rate
FICA = Social Security Tax + Medicare Tax
After-Tax Annual Salary = Gross Salary − Federal Income Tax − FICA
After-Tax Monthly Salary = After-Tax Annual Salary ÷ 12
After-Tax Bi-Weekly Salary = After-Tax Annual Salary ÷ 26
After-Tax Weekly Salary = After-Tax Annual Salary ÷ 52
Calculation Methodology
This calculator uses a deterministic federal-tax estimate flow. First, it applies the standard deduction tied to the selected filing status. Next, it calculates taxable income and applies progressive U.S. federal tax brackets to estimate federal income tax. If the FICA option is enabled, it also estimates Social Security tax up to the annual wage base and Medicare tax on wages.
Total estimated taxes are then subtracted from gross salary to produce estimated net annual pay. That net figure is converted into monthly, bi-weekly, and weekly estimates. All calculations run locally in the browser and no personal data is collected or stored.

- Checking whether a salary offer still works after federal taxes.
- Comparing two jobs with different gross salaries.
