Terms of Use

Free to use

Every tool on ToolUstad is free to use for personal and commercial purposes. There is no sign-up and no account.

Provided as-is

The tools are provided as-is, without any warranty of any kind. We do not promise that a tool is error-free, always available, or fit for a particular purpose.

Estimates, not professional advice

Calculator results are estimates. They are not professional advice. That applies in particular to the finance, tax, health and legal calculators: a mortgage, tax or health figure from this site is a starting point, not a substitute for a qualified adviser, accountant, doctor or lawyer. Check important figures with the original source or a professional before you act on them.

Your responsibility

You are responsible for checking important figures before you rely on them. If a result looks wrong, tell us through the Report an Issue box on the tool page or by email at [email protected].

Changes

We may change, add or remove tools at any time, without notice.
