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.
