Percentage Error Formula


The percentage error gives you the difference between the approximate and exact values as a percentage of the exact value and can help you see how close your guess or estimate This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100. Add a percent or % symbol to report your percent error value.Percent Error Example Please enter a valid email address.
