%

Formula Summary
Federal withholding estimate = gross bonus x federal supplemental rate
State/local withholding estimate = gross bonus x state/local rate
Total withholding estimate = federal withholding + state/local withholding
Estimated net bonus = gross bonus - total withholding estimate
Net bonus per paycheck equivalent = estimated net bonus / pay periods per year
How It Works
Bonus withholding often differs from regular payroll treatment, so explicit withholding assumptions improve planning clarity.
This model estimates withheld amounts at user-entered rates and reports estimated net bonus cash.
- Federal withholding estimate = bonus x federal supplemental rate.
- State/local withholding estimate = bonus x state/local rate.
- Total withholding estimate = federal + state/local withholding.
- Estimated net bonus = gross bonus - total withholding.
- Per-paycheck equivalent = estimated net bonus / pay periods per year.
Example Calculations
Typical supplemental withholding case
$12,000 bonus, 22% federal rate, 5% state rate, bi-weekly pay
$8,760 estimated net bonus and $336.92 net paycheck equivalent
Bonus tax impact can materially reduce immediate cash received.
No state tax scenario
$9,500 bonus, 22% federal rate, 0% state rate, semi-monthly pay
$7,410 estimated net bonus and $308.75 net paycheck equivalent
State withholding assumptions can significantly change net outcome.
Higher combined withholding
$25,000 bonus, 30% federal rate, 7% state rate, monthly pay
$15,750 estimated net bonus and $1,312.50 net paycheck equivalent
Large bonuses should be planned with conservative tax assumptions.
Frequently Asked Questions
Is withholding the same as final tax due?
Not always. Withholding is an estimate collected during the year; final tax liability can be higher or lower.
What federal bonus rate should I use?
Use your payroll or plan assumptions. The default is a common supplemental withholding baseline for planning.
Why ask for pay periods in a bonus calculator?
It provides a paycheck-equivalent view so bonus impact can be compared with regular payroll amounts.
Does this include retirement or benefit deductions on bonuses?
No. Add those manually by adjusting bonus amount or withholding assumptions.
