Many income claims leave out fees and tax. This is plain arithmetic, so it is only as good as the numbers you enter.

How the sum works

  1. HoursOnly paid hours: finding work and admin count as unpaid.
  2. MonthsWe use 52 weeks a year, divided by 12.
  3. TaxUse your own rate. In the US, self-employment tax alone is 15.3%.

Keep in mind

  • This is arithmetic, not a forecast.
  • Your own costs are not counted.
  • Tax rules differ by country.
