Understanding the Typing Accuracy Formula
Keystroke accuracy measures the percentage of keys you press correctly on the first attempt:
- Correct Keystrokes:
Total Keystrokes − Error Keystrokes - Accuracy Percentage:
(Correct Keystrokes ÷ Total Keystrokes) × 100
Error Allowance by Accuracy Target (Per 300 Characters / ~60 Words)
- 99% Accuracy: Maximum of 3 errors per 300 characters.
- 98% Accuracy: Maximum of 6 errors per 300 characters.
- 95% Accuracy: Maximum of 15 errors per 300 characters.
- 90% Accuracy: 30 errors per 300 characters (1 error every 2 words).
