How WPM is calculated in a typing test
Words per minute turns typed characters and elapsed time into one speed measurement. Monkey Typing uses five correct characters as one standardized word. This makes the calculation independent of whether a practice passage contains many short words or a few long ones.
The formula used here
WPM = correct characters retained ÷ 5 ÷ elapsed minutes. Correct characters include valid spaces between words. A character counts toward this score only when it matches the corresponding character in the target. Extra or incorrect characters do not add to your correct-character total.
For example, retaining 250 correct characters in one minute gives 250 ÷ 5 ÷ 1 = 50 WPM. Retaining 50 correct characters in 30 seconds gives 50 ÷ 5 ÷ 0.5 = 20 WPM. A word such as “keyboard” is not counted as one unit simply because it is a single dictionary word.
When the clock starts and stops
The clock starts on your first valid character input, so time spent choosing a mode or reading the opening words is not part of the attempt. In Time mode, the selected duration sets the end of the test. The clock continues if you switch to another browser tab. Returning after the deadline ends the attempt at that deadline.
Words, Quote, and Custom modes use the actual elapsed time until completion. A short completed passage can therefore produce a volatile score: a small pause changes a large part of its total duration. For a more repeatable comparison, use the same mode and enough text to settle into a rhythm.
Accuracy measures your input attempts
Accuracy = correct recorded input attempts ÷ all recorded input attempts × 100. For example, 90 correct attempts out of 100 gives 90% accuracy. Accuracy describes how often you entered the intended character or valid word separator, rather than how clean the finished text looks.
Deleting an error does not delete its recorded attempt. Typing the correct replacement adds another attempt. Navigation keys and Backspace are not character attempts, and ignored repeated spaces do not inflate the total. This helps distinguish a smoothly typed passage from one that required many corrections.
How corrections affect the result
Suppose you enter a wrong letter, delete it, and enter the correct letter. The corrected letter can count toward retained correct characters and therefore WPM. The original incorrect input remains part of your accuracy history. The time spent fixing it also remains part of the attempt.
This is why speed and accuracy should be read together. Two attempts may have similar WPM while one requires much more correction. If you want a more comfortable everyday typing pace, the attempt with fewer interruptions can be the more useful model for your practice.
Compare like-for-like results
Different typing websites can apply different scoring rules, word lists, and error penalties. A score from one tool may not be directly comparable to a score from another. Even here, punctuation, capitals, numbers, duration, and custom vocabulary can change the difficulty. Keep those settings consistent when checking your progress.
Use a one-minute test for a quick check, a three-minute test to practice consistency, and a five-minute test for a longer session. The speed chart shows how your cumulative WPM develops during the attempt; it is not a separate scoring system. Start a test on the Monkey Typing home page and review speed alongside accuracy.
