A small collection of free tools for everyday questions — no sign-up, no download, just the answer.
The Useful Site brings together ten single-purpose tools:
Every tool runs entirely in your web browser. The numbers you type never leave your device — there is nothing to install and no account to create. See the Privacy Policy for the details.
Calculator results are estimates worked out from the figures you enter. Prices and rates that come from outside the site — currency exchange rates and gas prices — are labeled snapshots taken from public sources, and each page says when its snapshot was taken. Everything here is provided for general information only; it is not financial advice. For a decision that matters, check the figure with your lender, dealer or bank.
The tools are free to use and are supported by advertising.
Questions, corrections or suggestions are welcome at [email protected].
