How it works

Percentage change is (End − Start) ÷ |Start| × 100.

CAGR is the steady yearly rate that would turn the starting value into the ending value: (End ÷ Start)1/years − 1. It smooths out volatility, so the actual year-to-year path may have been very different. CAGR needs positive start and end values.
