How to use the Number Sum Calculator

  1. Enter or paste your input in the box (or set the options, if the tool needs no input).
  2. Adjust the options to match what you need — the result updates as you type.
  3. Copy the result or download it, and keep editing if you want a different outcome.

What does this tool do?

Paste numbers separated by new lines, commas or spaces — even mixed into text — and the calculator picks out every number it finds. Thousands separators such as 1,250 are understood, and decimals and negatives work too.

Everything runs in your browser, so nothing you enter is uploaded or stored.

Why use it?

  • Free, with no sign-up and no limits.
  • Instant results as you type.
  • Private — your data stays on your device.
