Choose the value to solve for: WPM, CPM, characters per word, typing time, required rate, word amount, or 10-key rate/time/amount. The timed test measures gross speed and positional accuracy of retained text; select Calculate to start and again to score.

Five characters per word is the standard typing-test convention. Change it for a measured text average.

Characters Per Minute Formula

CPM = WPM ร— CPW

Variables:

  • CPM is the Characters Per Minute (characters/min)
  • WPM is the words per minute (wpm)
  • CPW is the characters per word

To calculate characters per minute, multiply words per minute by characters per word. A standard typing-test word is five characters, including spaces and punctuation; this is a scoring convention rather than the average length of an English word. Choose the same convention for both speeds, or enter a measured text average.

How to Calculate Characters Per Minute?

The following steps outline how to calculate the Characters Per Minute.


  1. First, determine the words per minute (wpm). 
  2. Next, determine the characters per word. 
  3. Next, gather the formula from above = CPM = WPM * CPW.
  4. Finally, calculate the Characters Per Minute.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example: CPM = 89 ร— 12 = 1,068 characters per minute.

words per minute (wpm) = 89

characters per word = 12

Frequently Asked Questions

What is the significance of calculating Characters Per Minute (CPM)?

CPM measures a character-entry rate. It can help track typing speed when the counting convention and test conditions stay consistent. It does not by itself measure reading speed, readability, or proficiency; the timed test here reports gross retained-text speed separately from positional accuracy.

How can I improve my WPM and CPM?

Improving WPM and CPM can be achieved through regular practice, typing exercises, and using typing software. Focusing on accuracy before speed, learning to touch type, and familiarizing yourself with the keyboard layout can also significantly boost your typing speed and efficiency over time.

Are there tools or software recommended for measuring WPM and CPM?

Yes, there are several online tools and software available for measuring WPM and CPM. Websites like TypingTest.com, 10FastFingers, and the calculators provided in the article are great resources. These platforms often offer typing tests, exercises, and games to practice and track your progress.

Is there a standard number of characters per word used in calculating CPM?

Typing tests commonly define one standard word as five typed characters, including spaces and punctuation. This does not mean an English word averages five characters. For text-specific conversions, use a consistently counted average; for standardized gross WPM, use five.
