What is a Percentage Change Calculator?
A Percentage Change Calculator measures the relative difference between two values expressed as a percentage. It calculates how much a quantity has increased or decreased from its original value to its final value. This essential financial tool helps analyze growth rates, price changes, performance metrics, and statistical variations. Widely used in economics, business, and everyday calculations, it simplifies comparing changes across different scales by converting absolute differences into percentage terms, making data more comparable and understandable.
Percentage Change Formula
[(Final Value - Initial Value) / |Initial Value|] × 100
