When you receive a bonus at work, one of the biggest questions is: How much will I actually take home after taxes? Employers often deduct federal income tax, state tax, Social Security, Medicare, and sometimes other withholdings before you see your final payment. To simplify this, a Bonus Net Pay Calculator helps you estimate how much of your gross bonus amount will remain in your pocket.
Bonus Net Pay Calculator
How to Use the Bonus Net Pay Calculator
Using this calculator is simple and requires just a few inputs:
- Enter Gross Bonus Amount – Input the total bonus amount your employer is giving you.
- Select Tax Filing Status – Choose whether you are single, married, or head of household.
- Input Federal and State Tax Rates – Federal withholding on bonuses is often 22% (flat supplemental rate), but your actual rate may vary. Enter applicable state tax as well.
- Add Deductions (if applicable) – Some employers may deduct retirement contributions or other benefits.
- View Net Bonus Pay – The calculator instantly shows your after-tax bonus pay.
Formula Behind Bonus Net Pay
The calculation can be broken down into a simple formula:
Net Bonus = Gross Bonus – (Federal Tax + State Tax + Social Security + Medicare + Other Deductions)
Where:
- Federal Tax = Gross Bonus × Federal Withholding Rate
- State Tax = Gross Bonus × State Withholding Rate
- Social Security Tax = Gross Bonus × 6.2% (up to the wage cap)
- Medicare Tax = Gross Bonus × 1.45% (plus 0.9% if income exceeds $200,000)
- Other Deductions = Retirement, insurance, or garnishments if applicable
This formula ensures a realistic estimate of what lands in your bank account.
Example Calculation
Suppose you receive a $5,000 bonus and live in a state with a 5% tax rate. Your employer applies federal withholding at 22%, plus Social Security and Medicare.
- Federal Tax = $5,000 × 22% = $1,100
- State Tax = $5,000 × 5% = $250
- Social Security = $5,000 × 6.2% = $310
- Medicare = $5,000 × 1.45% = $72.50
Total Deductions = $1,100 + $250 + $310 + $72.50 = $1,732.50
Net Bonus Pay = $5,000 – $1,732.50 = $3,267.50
So, from a $5,000 bonus, you’d actually take home around $3,267.50.
