🔢 What Is Relative Change?
Relative change measures the difference between an initial value and a final value, relative to the size of the initial value, and expresses it as a percentage. A positive relative change means the value increased, while a negative relative change means the value decreased.
📐 Relative Change Formula
The result is expressed as a percentage. A result of 0% means there was no change; positive values indicate growth, and negative values indicate decline.
✍️ Example Calculation:
Suppose a value increases from 80 to 100.
For a decrease, a value dropping from 80 to 60 gives (60 − 80) ÷ 80 × 100 = −25%, showing a relative decrease of the same size.
