How it works

Withholding amounts = gross × each rate. Net = gross − total withholding.

Formula

Federal = Gross × Fed%
State = Gross × State%
FICA = Gross × FICA%
Net = Gross − (Federal + State + FICA)

When to use it

  • Previewing take-home from a bonus payout.
  • Checking tax impact when changing state rates.
  • Pairing with gross-up to see net from gross and vice versa.

Tips & cautions

  • If over Social Security cap, lower the FICA portion accordingly.
  • Add local taxes by increasing the state rate if needed.
  • This is a flat-rate estimate; payroll may vary slightly.
  • Does not model local taxes or wage base caps.
  • Ignores deductions/benefits that reduce taxable wages.
