# How to Calculate Percent Error?

To calculate percent error use the formula of estimated value - actual value/ actual value * 100 percent. Subtract actual value, or correct value, from your estimated value, which can be a negative number. This is the absolute error. Divide absolute error by actual value, you will have a number less than one like 0.95 for relative error. Multiply relative error by 100 percent for percent error.
