Enter the total number of words, the minutes spent typing, and the average word length into the calculator to determine the letters per minute. This calculator helps to evaluate typing speed or reading speed in terms of letters per minute.

## Letters Per Minute Formula

The following formula is used to calculate the letters per minute.

LPM = (W * AWL) / M

Variables:

- LPM is the letters per minute
- W is the total number of words
- AWL is the average word length in letters
- M is the time in minutes

To calculate the letters per minute, multiply the total number of words by the average word length in letters, then divide by the time in minutes.

## What is Letters Per Minute?

Letters per minute (LPM) is a measure of typing or reading speed. It represents the number of letters that can be typed or read within one minute. This metric is useful for assessing the efficiency of typists, the difficulty of texts based on their language complexity, and for setting goals for improvement in typing or reading skills.

## How to Calculate Letters Per Minute?

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

- First, determine the total number of words typed or read (W).
- Next, determine the average word length in letters (AWL).
- Next, determine the time spent typing or reading in minutes (M).
- Next, gather the formula from above = LPM = (W * AWL) / M.
- Finally, calculate the Letters Per Minute (LPM).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

Total number of words (W) = 300 words

Average word length (AWL) = 5 letters

Time spent typing or reading (M) = 10 minutes
