What this calculator does

Useful for salary negotiations, contractor rates or relocating: tell the tool the net amount you need and it searches for the gross salary that produces it.

Formula and method

Solves gross such that net(gross) = target, by bisection, using the gross-to-net model.

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Desired net annual pay: 42660 (any currency)
  • Pre-tax retirement contributions (% of gross): 5 %
  • Tax-free allowance / standard deduction: 0 (any currency)
  • Tax brackets (upper limit:rate %): 10000:10, 40000:15, 90000:25, *:35
  • Social security / payroll contributions (% of gross): 7.65 %
  • After-tax deductions per year: 0 (any currency)

Results

  • Required gross annual salary: 60,000
  • Gross per month: 5,000
  • Income tax: 9,750
  • Social contributions: 4,590

How to read the results

Because tax is progressive, each extra unit of net pay costs more gross pay at higher incomes.

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 it an iterative search?

With brackets and allowances there is no simple closed-form inverse, so the tool searches numerically to the cent.
