Overview
Relative average compares the mean of a set of values with a reference value. If average sales are 90 and the target is 100, the relative average is 90%, meaning performance reached 90% of the target.
Formula
Relative average = (sum of values ÷ count) ÷ reference value × 100.

Worked examples
Example 1: 80, 90, 100 with reference 90
The mean is 90, and the relative average is 100%.
Example 2: 40, 50, 60 with reference 50
The mean is 50, and the relative average is 100%.

What does 100% mean?
It means the mean of the values equals the reference value.
Can the reference value be negative?
Yes, but the interpretation depends on the direction of the reference.
