What is the difference between gross WPM and net WPM?
Gross WPM measures raw speed — every character typed, divided by 5, divided by minutes. Net WPM deducts a penalty for errors — typically 1 WPM subtracted per uncorrected mistake. Most tests report net WPM because it rewards accuracy alongside speed.
| Metric | Formula | What it measures |
|---|---|---|
| Gross WPM | (Total chars ÷ 5) ÷ minutes | Raw typing speed, ignoring errors |
| Net WPM | Gross WPM − (Errors × 1) | Usable output — speed minus mistakes |
| Accuracy % | (Correct chars ÷ Total chars) × 100 | The ratio of correct keystrokes |
| KPM (keys per minute) | Total keystrokes ÷ minutes | Used in some data entry benchmarks |
Example: if you type 80 gross WPM with 5 errors, your net WPM is 75. If you type 90 gross WPM with 20 errors, your net WPM is 70 — meaning the slower, more accurate typist beats you on the metric that matters. This is why focusing on accuracy rather than raw speed is the correct approach to improving your score on the Typing Speed test.
Corrected vs. uncorrected errors: Some tests count only errors you failed to fix (uncorrected errors); others count all errors regardless of whether you backspaced to correct them. Human Benchmark counts uncorrected errors — if you backspace and retype, the mistake doesn't count.

Quick Answer
Gross WPM counts all words typed. Net WPM subtracts errors (typically 1 WPM per uncorrected mistake). Most typing tests report net WPM — it rewards accuracy, not just speed.
