About Toolora

Toolora is a growing set of free utilities — currently 110 tools across 8 categories. Each one does a single job, gives you the answer immediately, and shows the formula behind it so you can check the working rather than take it on trust.

There is no account, no paywall and no trial. Open a tool, use it, close the tab.

Every tool currently on the site runs entirely in your browser using ordinary JavaScript. There is no server doing the calculation, which means nothing you type is transmitted, logged or stored anywhere. It also means the tools keep working if your connection drops after the page has loaded.

Pages are pre-rendered ahead of time and each tool loads only its own code, so opening one does not drag in the rest of the site.

The finance tools use standard formulas and are useful for comparing options, but they are informational. They exclude fees, taxes and lender-specific rounding, and they are not financial advice. The same applies elsewhere: these are calculators, not professional guidance.

The list of tools grows regularly. If a tool you need is not here, tell us what you were looking for — that is how most of them get chosen.
