What to include

  • Reporting an error: the calculator, the inputs you used and the result you expected. A shared link from the calculator is ideal.
  • Suggesting a calculator: what you want to work out and who it would help.
  • Embedding or partnerships: your website and how you plan to use our tools. Embedding is free; see the embed page.

We can't give personal advice

We are not able to advise on individual tax, investment or loan decisions. For that, please speak to a qualified chartered accountant or adviser.
