What is WCPM (Words Correct Per Minute)?
WCPM stands for Words Correct Per Minute. It is the standard metric used by educators to assess reading fluency and by employers to test typing accuracy.
Unlike simple WPM (Words Per Minute), WCPM accounts for errors. It calculates the net number of correct words produced in one minute, providing a clearer indication of true skill and comprehension.
How to Calculate WCPM?
The formula is strict but fair. Our AI tool automates this process:
Count every word attempted during the timed session.
Remove mispronounced, skipped, or misspelled words.
Divide the remaining correct words by the total minutes.
For reading assessments, if a student self-corrects a mistake within 3 seconds, it is usually NOT counted as an error. However, our calculator assumes all entered "Total Errors" are uncorrected mistakes.

Frequently Asked Questions
What counts as an error?
In reading: mispronunciations, substitutions, and omissions. In typing: misspelled words, incorrect punctuation, and capitalization errors.
Is high speed always better?
No. If you read 200 words per minute but make 50 errors, your WCPM is only 150, and your comprehension is likely very poor. The goal is a balance of speed and accuracy.
