Convert gross pay into net pay after taxes and deductions. To use the Gross to Net Calculator, enter gross annual pay, state tax rate, pre-tax 401 and health, post-tax deductions; it returns net annual pay, federal income tax, fica, net monthly, and shows them instantly as you type.
Where the Gross to Net Calculator fits
Convert gross pay into net pay after taxes and deductions. The main figure it returns is the Net annual pay, worked out from the values you enter.
It belongs with the other tax & salary tools. If you are comparing options or checking a result from another angle, try the Net to Gross Calculator, Take-Home-Paycheck Calculator or the Adjusted Gross Income (AGI) Calculator.
How to use the Gross to Net Calculator
- Enter your numbers. Start with Gross annual pay ($), State tax rate (%), Pre-tax 401(k) and health ($), then fill in Post-tax deductions ($). Use the tax year and filing status that apply to you, and gross figures unless a field says otherwise. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Net annual pay, and the cards below show Federal income tax, FICA, Net monthly. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Gross to Net Calculator using the default values shown in the calculator above:
Inputs
| Gross annual pay ($) | 90,000 |
|---|---|
| State tax rate (%) | 4 |
| Pre-tax 401(k) and health ($) | 8,000 |
| Post-tax deductions ($) | 1,200 |
Results
| Net annual pay | $61,425.00 |
|---|---|
| Federal income tax | $9,210.00 |
| FICA | $6,885.00 |
| Net monthly | $5,118.75 |
With these inputs the calculator returns Net annual pay: $61,425.00. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Gross annual pay ($) from 90,000 to 108,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Net annual pay | $61,425.00 | $73,368.00 | +19.4% |
| Federal income tax | $9,210.00 | $13,170.00 | +43% |
| FICA | $6,885.00 | $8,262.00 | +20% |
| Net monthly | $5,118.75 | $6,114.00 | +19.4% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.

Method and limits. This calculator applies the formula in the section above to your inputs, in your browser; nothing you enter is stored on our servers. Tax rules change every year and depend on your full situation (state, filing status, credits), so treat the result as an estimate and confirm it with the IRS or a tax professional. It is for information, not financial, tax or legal advice.
Frequently asked questions
Why is net pay lower than gross?

Which tax year and rates are used?
US federal brackets and standard deductions for 2026 and 2025, plus FICA. State tax is a rate you enter.
Are the results guaranteed?
No. Results depend entirely on the numbers you enter and the formulas shown on this page. Please do not make financial decisions based on them alone; confirm important figures with a licensed professional.
