Percent Error Calculator, also known as Percentage Error Calculator is the online statistics tool for data analysis programmed to perform the comparison between observed value and true value. A more useful way to measure your accuracy is to find the percent error between the two values. Finding the percent error is simple.


Percent or Percentage error is the error applied when comparing an experimental observed quantity E, with a theoretical quantity T, which is considered the True Value. The percent error is the absolute value of the difference divided by the True Value times 100.

Percent Error Formula

Percent Error can be calculated from the formula
Percent Error = ((True Value - Observed Value)/ True Value) x 100
