Questions, corrections and ideas are welcome.
We read every message about errors, suggestions and general questions.
What to include
- For a calculation error: the tool name, the numbers you entered and the result you expected, with how you worked it out. For tax figures, please tell us the official source.
- For a feature idea: a short description of the tool you need.
- For privacy requests: see the options in our Privacy Policy.
What we cannot do
We cannot provide personal financial, tax or legal advice, and we cannot see or recover anything you have typed into a tool, because the calculations happen in your browser.
