What this calculator does

Bonuses are often taxed or withheld at a flat supplemental rate. Employers sometimes “gross up” a bonus so the employee receives a specific net amount.

Formula and method

Net bonus = gross × (1 − withholding); Gross-up: gross = target net ÷ (1 − withholding)

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Calculate: Net bonus from a gross bonus
  • Annual salary (for % bonus): 60000 (any currency)
  • Bonus as % of salary: 10 %
  • Withholding rate on bonuses: 22 %

Results

  • Net bonus: 4,680
  • Gross bonus: 6,000
  • Withholding: 1,320

How to read the results

Withholding is not necessarily the final tax; the year-end tax calculation may differ.

Assumptions and limitations

  • Tax rules differ by country, region and year. Enter the official rates and brackets that apply to you; the defaults are illustrative and do not represent any jurisdiction. This is not tax advice.

Tax and payroll figures depend on rules that differ by country, region and year and change often. Enter official current rates, and consult the tax authority or a qualified adviser — nothing here is tax advice.

Questions

Why is my bonus taxed so heavily?

Flat withholding rates can exceed your average rate; the difference may be reconciled when you file.
