Typing Speed Calculator
Calculate your net typing speed (WPM) and accuracy from words typed, time taken, and errors.
How the calculation works
Gross words per minute measures raw typing throughput. Net WPM, the number most typing tests report as your real speed, subtracts a penalty for errors made per minute, so mistakes cost you speed even if your fingers were moving fast. Accuracy separately shows what share of your total words were typed correctly.
Formula
Gross WPM = Words Typed ÷ Time (minutes). Net WPM = Gross WPM − (Errors ÷ Time). Accuracy = (Words Typed − Errors) ÷ Words Typed × 100.
Examples
250 words in 5 minutes, 5 errors
50 gross WPM, 49 net WPM, 98.00% accuracy
180 words in 3 minutes, 9 errors
60 gross WPM, 57 net WPM, 95.00% accuracy
