Typing metrics guide

Recommended: use these formulas when comparing a result with another typing tool.

Words per minute

A word is normalized to six typed characters. WPM is calculated from correct characters only:

wpm = (correctCharacters / 6) / elapsedMinutes

Accuracy

Accuracy compares correct characters with the complete expected prompt:

accuracy = correctCharacters / promptLength * 100

Example

In a 30-second test with 240 correct characters, the result is 80 WPM.
