What is Rate of Change?

Rate of change measures how one quantity changes in relation to another. Whether it's positive (an increase) or negative (a decrease), knowing the rate of change provides valuable insights. It's often visualized as the slope of a line on a graph.

Our calculator focuses on percentage changes, allowing you to understand proportional increases or decreases. While other calculators might focus on linear rate of change (slope) using coordinate points, this tool excels at percentage-based analysis.
