# What is my typing speed in WPM?

Computes typing speed in words per minute from the characters or words typed and the time, with net WPM after uncorrected errors, accuracy, and characters per minute.

## Default answer

Example with the default inputs (I counted Characters, Characters typed 1,250, Time 5 min, Uncorrected errors 0): You type 50 words per minute (50 net WPM, 100% accuracy).

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| by | I counted | Whether you counted characters (every keystroke, spaces included) or whole words. |
| c | Characters typed | Every character typed, spaces and punctuation included. |
| n | Words typed | The number of whole words typed. |
| t | Time | How long the typing took. |
| e | Uncorrected errors | Mistakes left in the text: wrong characters when you counted characters, wrong words otherwise. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| wpm | Gross WPM | Words (5 characters each, or whole words) ÷ minutes. |
| net | Net WPM | Gross WPM − uncorrected errors ÷ minutes, never below 0. |
| accuracy | Accuracy | The share typed without an error: (typed − errors) ÷ typed × 100. |
| cpm | Characters per minute | Characters ÷ minutes (when you counted characters). |
| minutes | Minutes | The time in minutes. |

## Method

Gross WPM = (characters ÷ 5) ÷ minutes, or words ÷ minutes; net WPM = gross WPM − uncorrected errors ÷ minutes (at least 0); accuracy = (typed − errors) ÷ typed × 100; CPM = characters ÷ minutes.

## Assumptions

- A standard word is 5 characters, spaces and punctuation included (Arif and Stuerzlinger, 2009).
- Errors are mistakes left in the text, counted in the same thing you counted: characters or words.
- Net WPM never goes below 0.

## Worked examples

1. by = chars, c = 1,250, t = 300, e = 15 gives wpm = 50, net = 47, accuracy = 98.8%, cpm = 250. Source: Arif and Stuerzlinger, 2009, Analysis of Text Entry Performance Metrics (a word is 5 characters, spaces included), cited by Words per minute, https://en.wikipedia.org/wiki/Words_per_minute.
2. by = chars, c = 200, t = 60, e = 10 gives wpm = 40, net = 30, accuracy = 95%. Source: Type to Learn, How are Words Per Minute and Accuracy Calculated? (words = keys pressed ÷ 5; accuracy = 190 ÷ 200 × 100 = 95%), https://www.typetolearn.app/knowledge-base/how-words-per-minute-and-accuracy-are-calculated/.
3. by = words, n = 300, t = 270 gives wpm = 66.666667, net = 66.666667, accuracy = 100%, minutes = 4.5. Source: Words per minute (words ÷ minutes), https://en.wikipedia.org/wiki/Words_per_minute.

## FAQ

### How is WPM calculated?

Divide the characters you typed by 5, then divide by the minutes. Typing tests count a word as 5 characters, spaces and punctuation included, so long and short words count the same. 1,250 characters in 5 minutes is 250 words ÷ 5 = 50 WPM.

### What is net WPM?

Gross WPM minus the uncorrected errors per minute. With 15 errors left in a 5 minute test, net WPM is 50 − 15 ÷ 5 = 47. Errors you fix while typing cost time instead, so they already lower the gross speed.

### How is typing accuracy calculated?

The share of what you typed that is right: (typed − errors) ÷ typed × 100. 190 right out of 200 keys is 95%.

### Why count 5 characters as a word instead of real words?

Real words differ in length, so a text full of short words would look faster. A fixed 5-character word lets you compare tests, texts and even languages. If you only counted whole words, choose Words and the calculator divides them by the minutes.

### What is a good typing speed?

There is no single standard. Compare your net WPM, not the gross figure, with the speed a job or class asks for, and time a test of several minutes. Accuracy matters as much as speed.

### How do I turn characters per minute into WPM?

Divide by 5. 300 characters per minute is 60 WPM.
