What is CAGR and How to Calculate It
CAGR (Compound Annual Growth Rate) is the rate at which an investment would have grown if it grew at a perfectly steady rate each year. It's the gold standard for comparing investment returns because it accounts for compounding β the key driver of long-term wealth creation.
Example: $10,000 β $25,000 in 10 years = (25000/10000)^(1/10) β 1 = 9.6% CAGR
Why CAGR Beats Average Annual Return
If a stock gains 100% one year and loses 50% the next, the average return is 25% β but you've broken even. CAGR correctly reports 0% because it measures actual end value vs start value. Always use CAGR to evaluate real investment performance over multiple years.
