About ToolMoose

ToolMoose is a growing collection of fast, free calculators. The idea is simple: when you need to work something out, you should get a clear answer in seconds without fighting pop-ups, logins, or a wall of ads.

What makes our tools different

• They run in your browser. Calculations happen on your device, so they are instant and private.
• They explain themselves. Every calculator includes the formula, worked examples, and answers to common questions, so you can trust the result and learn how it works.
• They stay out of the way. No account, no paywall, minimal clutter.

Who it is for

Students checking a GPA, workers totaling a time card, anyone splitting a restaurant bill, and people who just want a percentage worked out correctly. If a task is common and the math is well-defined, it belongs here.

How it is funded

ToolMoose is free to use. To cover hosting and development, the site may show advertising. That is the only reason ads exist here, and we aim to keep them unobtrusive. See our privacy policy for details on cookies and consent.
