How to use the Bonus Calculator

- Enter the amounts and the withholding rate.
- Read the gross, tax and net bonus.
What does this tool do?
Bonuses are often withheld at a flat supplemental rate — 22% for US federal tax on bonuses up to $1 million — plus state and social taxes. The gross-up mode works backwards to the gross bonus needed for a chosen take-home amount.
Withholding isn't necessarily your final tax bill; the bonus is added to your income when you file.
Why use it?
- Three bonus modes.
- Gross-up for employers.
- Any withholding rate.
Accuracy and limits
- For planning and education — not financial, tax or legal advice.
