# Percent of Change

Percent of change is a fundamental concept in mathematics and economics used to quantify the difference between two values in terms of a percentage. It provides a clear understanding of the relative increase or decrease from an initial value to a final one. Whether assessing financial investments, analyzing trends in data, or evaluating the impact of policy changes, percent of change serves as a vital tool for decision-making and forecasting. By expressing shifts in numerical terms relative to their original values, it enables concise comparisons and facilitates meaningful interpretations across various contexts.
