Enter the number of self-corrections and the number of errors into the Self Correction Ratio Calculator. The calculator will evaluate and display the Self Correction Ratio.

## Self Correction Ratio Formula

The following formula is used to calculate the Self Correction Ratio.

SCR = (SC + E) / SC
• Where SCR is the Self Correction Ratio ( )
• SC is the number of self-corrections
• E is the number of errors

To calculate a self correction ratio, add together the number of self-correction and the number of errors, then divide by the number of self-corrections.

## How to Calculate Self Correction Ratio?

The following example problems outline how to calculate Self Correction Ratio.

Example Problem #1:

1. First, determine the number of self-corrections.
• The number of self-corrections is given as: 30.
2. Next, determine the number of errors.
• The number of errors is provided as: 20.
3. Finally, calculate the Self Correction Ratio using the equation above:

SCR = (#SC + #E) / #SC

The values given above are inserted into the equation below and the solution is calculated:

SCR = (30 +20) / 30 = 1.667

Example Problem #2:

For this problem, the variables required are provided below:

number of self-corrections = 40

number of errors = 10
