How the bonus calculator works
Enter a bonus as a flat amount or as a percentage of your salary, add your tax withholding rate, and the tool estimates what you keep after withholding. Bonuses are taxable income, and employers often withhold them at a flat supplemental rate, so the amount that hits your bank account is smaller than the headline figure.
How bonuses are taxed
In the US, employers commonly withhold federal tax on bonuses at a flat supplemental rate of 22 percent, with Social Security, Medicare, and any state tax on top. Withholding is not the same as your final tax bill: depending on your total income you may owe more or get some back at tax time. This tool uses the single rate you enter.
Flat amount or percent of salary
Switch the bonus type to enter either a fixed dollar amount or a percentage of your annual salary, such as a 10 percent target bonus. The calculator works out the gross bonus either way, then applies your withholding rate to estimate the net.
Important note
This is a general estimate for planning, not tax advice. Your actual withholding and final tax depend on your full financial picture, so check your pay stub and consult a tax professional. The monthly figure simply spreads the net bonus across a year for budgeting.
Frequently asked questions
How much of my bonus do I keep? Subtract your withholding rate; many US bonuses are withheld around 22 percent federally plus other taxes.
Why was so much taken from my bonus? Bonuses are often withheld at a flat supplemental rate plus FICA and state tax, which can feel high.
Will I get some back? Possibly, since withholding is not your final tax; it depends on your total income.
