Calculation path

Calculate mean absolute percentage error for three actual and predicted pairs. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

MAPE=100 mean(|A-P|/|A|)

What you provide

First actual value, using the same scenario as the other inputs
First predicted value, using the same scenario as the other inputs
Second actual value, using the same scenario as the other inputs
Second predicted value, using the same scenario as the other inputs
Third actual value, using the same scenario as the other inputs
Third predicted value, using the same scenario as the other inputs

What you receive

MAPE in % from the stated equation
A symbolic formula plus substituted working with your values
Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Actual values are nonzero and percentage error is meaningful on this outcome scale.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
