What is Percentage Change?
Percentage change is a way to express a change in a value relative to its original value. It is calculated using the formula:
Percentage Change = ((New Value - Old Value) / Old Value) * 100
This formula allows you to quantify how much a value has increased or decreased in percentage terms, making it easier to compare different scenarios.
