It's an easy way to see why accuracy matters: on a one minute test, every error costs a full word per minute.
How typing accuracy is calculated
Accuracy = (total keystrokes - incorrect keystrokes) / total keystrokes x 100. A keystroke is incorrect if it didn't match the expected character, even if you fixed it afterwards.
What errors cost
At the same typing pace, here's how accuracy changes net WPM on a 1 minute test with 300 keystrokes (60 gross WPM):
| Accuracy | Errors | Net WPM |
|---|---|---|
| 100% | 0 | 60 |
| 98% | 6 | 54 |
| 95% | 15 | 45 |
| 90% | 30 | 30 |

Frequently asked questions
What is good typing accuracy?
95% is a common minimum for jobs, and 98% or more is excellent.
Do corrected mistakes count?
Yes, for accuracy. They don't reduce net WPM directly, but the time spent fixing them does.
How can I improve my accuracy?
Slow down slightly, keep your fingers on the home row and practice your weakest keys.
