NPS Calculator — free online tool
You ran a survey and asked people how likely they are to recommend you, from 0 to 10. Now you're staring at a pile of numbers and trying to remember the formula for Net Promoter Score. We added a free tool that does it for you — NPS Calculator — right in your browser.
What it does
You can enter how many promoters, passives and detractors you have, or just paste your raw 0–10 scores and let it sort them. Either way it works out your Net Promoter Score in seconds, so you don't have to do the math by hand.
Nothing leaves your device
The whole thing runs in your browser. Your numbers are never uploaded anywhere and nothing is saved. When you close the tab, it's gone — it's just a quick calculation on your own screen.
How to use it
- Open NPS Calculator.
- Type your counts of promoters, passives and detractors, or paste your raw 0–10 scores.
- Read your NPS straight away and copy it wherever you need it.
It's free with no limit. There are more small tools on the Apps page.
