Enter the total number of words read and the total number of errors into the Reading Accuracy Rate Calculator. The calculator will evaluate the Reading Accuracy Rate.

## Reading Accuracy Rate Formula

The following two example problems outline the steps and information needed to calculate the Reading Accuracy Rate.

**RAR = (WR-E) / WR * 100**

- Where RAR is the Reading Accuracy Rate (%)
- WR is the total number of words read
- E is the total number of errors

## How to Calculate Reading Accuracy Rate?

The following example problems outline how to calculate Reading Accuracy Rate.

Example Problem #1:

- First, determine the total number of words read.
- The total number of words read is given as: 5,000.

- Next, determine the total number of errors.
- The total number of errors is provided as: 1,000.

- Finally, calculate the Reading Accuracy Rate using the equation above:

RAR = (WR-E) / WR * 100

The values provided above are inserted into the equation below and computed.

RAR = (5000-1000) / 5000 * 100 = 80.00 (%)

Example Problem #2:** **

For this problem, the variables required are provided below:

total number of words read = 600

total number of errors = 100

Test your knowledge using the equation and check your answer with the calculator.

RAR = (WR-E) / WR * 100** = ?**
