How WPM is calculated: gross, net and accuracy explained

Words per minute sounds simple, but words vary in length — "a" and "internationalisation" would count the same. So typing tests use a standard word instead.

A word is five characters

By convention, every five characters typed count as one word, and spaces count as characters. Typing 300 characters in a minute is 60 WPM, whatever the actual words were. This is what makes a result from one test comparable with another.

Gross WPM

Gross WPM counts every character you typed, right or wrong:

• Gross WPM = (all characters typed ÷ 5) ÷ minutes

It measures how fast your fingers moved, not how much correct text you produced.

Net WPM

Net WPM counts only what you got right:

• Net WPM = (correct characters ÷ 5) ÷ minutes

This is the headline number on Keyshand, and the more honest one — mistakes do not add to your score. Some tests instead subtract a penalty per uncorrected error from gross WPM; the idea is the same, and the results are close.

Accuracy

• Accuracy = correct keystrokes ÷ total keystrokes

Keyshand counts every keystroke, including ones you later corrected. So a mistake you fixed still lowers your accuracy — which is right, because fixing it still cost you time.

Consistency

Keyshand also reports consistency: how even the gaps between your keystrokes were. Two typists can have the same WPM with very different rhythm. Low consistency means bursts of speed separated by hesitations, and those hesitations usually come from the same few keys.

Per-key speed

The same arithmetic applies to a single key: the average time before each correct press of that key can be expressed as a speed. That is how Keyshand can say that your overall speed is 60 WPM but your q runs at 25 — and why the test can tell you which keys to practise.

Why results differ between tests

• Text. Common words are faster than rare ones; capitals, numbers and punctuation are slower.
• Length. A 15-second test is noisy. 60 seconds gives a steadier number.
• Formula. Net versus gross, and how errors are penalised.
• Corrections. Some tests force you to fix errors before continuing; others do not.

To track progress, use the same test at the same length each time. See what is a good typing speed for what the numbers mean.
