About

Our Mission
Get to a useful answer in one click — no buried formulas, no signup.
Why This Site?
- No account, no sign-up, no paywall.
- We do not save the values you enter to any database, link them to you or use them to target advertising. They are part of the page address, so they can appear in routine server logs (see the Privacy Policy); they are removed from the address our analytics receives.
- Mobile-friendly and fast on slow connections.
- 50+ language support for international visitors.
How the Site Is Funded
Advertising pays for the site, which is why it can stay free. See our Privacy Policy for what that means for your data.
How the Tools Are Built and Checked
Every calculator runs its own formula code on our server, so a result is worked out the same way every time and does not depend on your browser.
- Each tool has at least one automated test with known inputs and the expected answer — more than 5,000 tests in all — and the full set runs before any update goes live.
- The most-used tools explain the formula they apply, walk through a worked example and list common mistakes. The figures in each example come from the tool itself and are checked automatically, so the explanation cannot drift away from the result.
- Rules that change from year to year, such as tax brackets, get a separate page for each year, with the year named on the page.
- When we find or are told about an error, we correct the formula, add a test for that case so it cannot come back, and update the explanation.
A Note on the Results
Our calculators are informational tools, not professional advice — please read the Disclaimer before acting on a result.
