What is Growth Rate Calculator?
The Growth Rate Calculator tells you how much a value has grown or declined between two points — expressed as a percentage. It also calculates CAGR (Compound Annual Growth Rate) when you provide a time period, which is useful for comparing investments or business metrics that span multiple years.
Growth rate calculations are essential for business reporting, financial analysis, tracking user growth, measuring revenue trends, and evaluating any metric that changes over time.

Frequently asked questions
Growth rate is the simple percentage change from start to end. CAGR (Compound Annual Growth Rate) smooths the growth across multiple periods, giving you an equivalent constant rate per year. CAGR is more useful for multi-year comparisons.
It means the value declined. For example, -25% means the value fell by a quarter.
CAGR = (End Value / Start Value)^(1/n) − 1, where n is the number of periods (years). Multiply by 100 for a percentage.
