## Quick Answer

Calculate the average rate of change between two points or the instantaneous rate of change at a single point. Supports step-by-step worked solutions.

## Definition

A rate of change calculator is a calculus utility that measures how a dependent variable changes relative to an independent variable. It supports two modes of calculation: average rate of change, which computes the slope of the secant line between two distinct points, and instantaneous rate of change, which calculates the slope of the tangent line at a single point using symbolic differentiation. Students and researchers use it to analyze velocities, acceleration, growth rates, and general function behaviors with detailed mathematical step breakdowns.

## How to Use

1. **Enter your function** — Type the mathematical function you want to analyze in the input box.
2. **Choose the mode** — Select either average rate of change or instantaneous rate of change.
3. **Input the points** — Enter the required coordinate values for the interval or point of interest.
4. **Review the steps** — Check the computed rate of change along with the worked mathematical steps.
