Words Correct Per Minute (WCPM) Calculator

Formula

The formula to calculate the Words Correct Per Minute (WCPM) is:

$\text{WCPM} = \frac{\text{TW} - \text{M}}{\text{T}}$

Where:

$\text{WCPM}$ is the words correct per minute
$\text{TW}$ is the total number of words
$\text{M}$ is the total number of mistakes
$\text{T}$ is the total time in minutes

The formula for the time can be further broken down into:

$\text{T} = m + \frac{S}{60}$

Where:

$m$ is the number of minutes
$S$ is the number of seconds

What is WCPM?

Words Correct Per Minute (WCPM) is a metric used in teaching to understand the reading comprehension of students. It measures the number of words a student reads correctly in one minute, accounting for both speed and accuracy.

Example Calculation

Let's assume the following values:

Total Words (TW) = 100 words
Mistakes (M) = 5
Minutes (m) = 1
Seconds (s) = 30

Using the formula:

$\text{T} = 1 + \frac{30}{60} = 1.5 \text{ minutes}$ $\text{WCPM} = \frac{100 - 5}{1.5} \approx 63.33$

The Words Correct Per Minute (WCPM) is approximately 63.33 words per minute.
