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.
