Enter the total number of words and the number of errors into the calculator to determine the correction rate. This calculator helps to evaluate the quality of written text by providing the rate of errors per word.

Sentence Correction Rate Formula

The following formula is used to calculate the sentence correction rate.

CR = E / W

Variables:

  • CR is the correction rate (errors per word)
  • E is the number of errors
  • W is the number of words

To calculate the sentence correction rate, divide the number of errors by the number of words.

What is a Sentence Correction Rate?

The sentence correction rate is a measure of the frequency of errors in a piece of text. It is calculated by dividing the total number of errors by the total number of words. This rate can be used by editors, writers, and educators to assess the quality of writing and to identify areas that may need improvement.

How to Calculate Sentence Correction Rate?

The following steps outline how to calculate the Sentence Correction Rate.


  1. First, count the total number of words in the text (W).
  2. Next, count the total number of errors in the text (E).
  3. Use the formula CR = E / W to calculate the correction rate.
  4. Finally, calculate the Sentence Correction Rate (CR).
  5. 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.
