Typing Speed Calculator
Raw words-per-minute alone doesn't reflect real typing skill — a fast typist who makes lots of mistakes may have a similar effective output to a slower, more accurate one, which is exactly why this adjusts for errors to give a net WPM figure.

How the typing speed calculator works
Gross WPM = words typed ÷ minutes taken.
Net WPM = gross WPM − (errors ÷ minutes taken), effectively subtracting an error penalty rate from the raw typing speed.
Worked example: 320 words typed in 5 minutes, with 8 errors
- Gross WPM = 320 ÷ 5 = 64 WPM.
- Error penalty rate = 8 ÷ 5 = 1.6 WPM.
- Net WPM = 64 − 1.6 = 62.4, rounding to 62 WPM net.
Common mistakes to avoid
Comparing gross WPM figures between two typists without accounting for accuracy
A typist who types 70 gross WPM with 15 errors may have a lower net WPM than one who types 55 gross WPM with 2 errors — gross speed alone can be a misleading comparison without factoring in the error penalty.
Assuming 'errors' means the same thing across different typing tests
Different typing tests define and count errors somewhat differently (character-level mistakes versus whole incorrect words, for instance) — comparing net WPM scores from two different testing tools may not be a perfectly apples-to-apples comparison.
Frequently asked questions
Why does the calculation subtract an error penalty rather than just reducing the word count directly?
This specific formula treats errors as a rate-based penalty (errors per minute) subtracted from gross speed, which is one common convention among several possible ways different typing tests choose to penalise mistakes for a net score.
What's considered a 'good' typing speed?
This varies by context, but many general references suggest an average typist reaches somewhere in the 35-45 WPM range, with 60+ WPM considered fast, and touch-typing professionals sometimes well beyond that.
How can I actually improve my net WPM, not just gross WPM?
Focusing on accuracy alongside raw speed — since errors directly reduce net WPM in this formula, slowing down slightly to reduce mistakes can sometimes improve net WPM more than trying to type faster with more errors.
Does this account for backspacing and correcting mistakes during the test?
This specific calculation only needs the final words-typed and errors counts at the end of the timed period — it doesn't separately track how much time was spent correcting mistakes along the way.
