Everyday Calculators

12 free calculators · runs in your browser · nothing you type is stored

The quick ones you reach for between other things: what 15% off actually saves, how many days until a date, what a road trip costs in fuel, how to split a restaurant bill fairly. Each is built to give the answer in a few seconds and then get out of the way.

None of them stores what you type. A few — like the currency converter — use a preset rate you can override with your own, and say so on the page.
