Free online typing speed calculator

How to use

1. Enter the number of words typed (or leave at zero to derive from characters).
2. Enter the total character count.
3. Enter the elapsed time in decimal minutes.
4. Enter the number of errors made.
5. Click Calculate to see WPM, CPM, accuracy, and your performance category.

Formulas

standard word = 5 characters

WPM          = words / time (uses word count if provided; else chars / 5)

CPM          = characters / time

GWPM         = (characters / 5) / time   (gross WPM from characters)

accuracy (%) = (characters − errors × 5) / characters × 100

adjusted WPM = GWPM × (accuracy / 100)

categories:
  Beginner  < 30 WPM
  Average   30–50 WPM
  Good      51–70 WPM
  Fast      71–100 WPM
  Expert    > 100 WPM

Worked example

250 words, 1,250 characters, 5 minutes, 5 errors:

WPM          = 250 / 5 = 50 WPM

CPM          = 1,250 / 5 = 250 CPM

GWPM         = (1,250 / 5) / 5 = 50 GWPM

accuracy     = (1,250 − 5 × 5) / 1,250 × 100
             = 1,225 / 1,250 × 100 = 98%

adjusted WPM = 50 × 0.98 = 49 WPM
category     = Average

Notes

• The five-character word standard (used by most typing tests) does not match actual average English word length, but it is the universal benchmark.
• Some tests report net WPM by deducting one word per error from gross WPM. This calculator uses the accuracy-multiplier method instead.
