A fast, clean calculator with full keyboard support. Switch between Basic, Scientific,
and a set of practical mini-calculators (Percent, Tip Split, BMI, Unit Price, Date Difference).
Everything runs in your browser.
Yes. You can click/tap buttons, or type directly: digits, operators (+ − * /), parentheses, and decimal point. Press Enter for equals, Backspace to delete, Escape to clear.
Is it private?
Yes. Everything runs locally in your browser. Nothing is uploaded.
Can I pop it out while I work?
On many browsers/devices, Pop-out opens a small floating window. If your browser blocks it, you can still open the calculator in a separate tab/window and keep it alongside your work.
Can I share a specific calculator mode?
Yes. Share copies a link that opens the same tab (Basic/Scientific/Everyday/Help).
Shortcuts: Enter =, Esc clears, Backspace deletes, Ctrl/Cmd+C copies answer when focused.
