소개

Typing Speed Calculator — Words per minute and accuracy from characters typed and errors. Enter Characters typed, Time (minutes), Errors to get an instant, accurate result.

공식

Words per minute (WPM) = (characters typed ÷ 5) ÷ minutes elapsed, the standard "5 characters = 1 word" convention. Net WPM subtracts errors from the word count; accuracy % = (1 − errors/characters typed) × 100.

단계별 안내

  1. Enter the Characters typed.
  2. Enter the Time (minutes).
  3. Enter the Errors.
  4. Click Calculate to see your result instantly.

실제 예시

Example: With Characters typed = 250, Time (minutes) = 5, Errors = 0, the Typing Speed Calculator gives Wpm: 10, Net Wpm: 10, Accuracy Pct: 100.

자주 묻는 질문

Why divide characters by 5?
Five characters (including spaces) is the standard typing-industry approximation for the average length of one word.
What's the difference between WPM and net WPM?
WPM is your raw typing speed; net WPM subtracts your errors, giving a more accurate picture of correctly typed output.
What inputs does the Typing Speed Calculator need?
You'll need to provide: Characters typed, Time (minutes), Errors. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Typing Speed Calculator?
The Typing Speed Calculator applies the formula exactly as calculated — Words per minute (WPM) = (characters typed ÷ 5) ÷ minutes elapsed, the standard "5 characters = 1 word" convention. Net WPM subtracts errors from the word count; accuracy % = (1 − errors/characters typed) × 100. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Typing Speed Calculator free to use?
Yes, the Typing Speed Calculator is completely free, requires no signup, and runs instantly in your browser.
