    • Percent Error Formula | How to Calculate Percent Error | Examples

      To find the percent of error, you find the difference between the predicted value or amount and the actual value (subtracting the absolute value of the numbers so that you do not get negatives). The numerator is this difference. Next you divide by the denominator which is the estimated or predicted amount. You will get a decimal outcome.
