One tool, one page

Each page answers one need. When two pages did the same job we merged them and redirected the old address, so a search or a bookmark always lands on the current version.

Tool first, explanation after

The working tool is at the top of the page. Below it we explain how the result is produced. Tools rebuilt on our current template add a worked example and reference material such as tables or charts.

Sources and dates

Figures that can change, such as rates, thresholds or official dates, are taken from the organisation that sets them and linked on the page. Where a figure could not be confirmed at its source, the page says so. Every tool page carries the date it was last updated; we change that date only when the content or the data really changed.

Authors and reviewers

Pages name an author or reviewer only when a specific, qualified person has written or checked them. Where no name is shown, the page was produced by the tools.best team from the sources listed on it.

Corrections

If a result looks wrong, check the formula and sources on the page first; they show exactly what the tool does. Confirmed errors are fixed and the page date is updated.

What this site is not

tools.best provides utilities for convenience. Check a result before you rely on it in production, in print or in a transaction. Exchange rates and crypto prices come from third-party services, can be delayed, and are not the rate a bank or exchange will give you.
