Free Calculators and Guides for Your Members and Patrons

Small business owners ask the same questions: what to charge, how much to set aside for taxes, what an employee really costs. Use our calculators and guides for free. Add them to your website, link to them, or print them.

What you get

  • Calculators that run in the visitor’s browser. Nothing a visitor types is sent to us or stored. No sign-up and no ads.
  • Plain-English guides that show the arithmetic by hand and in a spreadsheet.
  • Sources and a review date on every page. Tax figures are checked every January.
