Compound annual growth rate (CAGR)
CAGR is the constant compounded yearly rate that would connect a beginning value with an ending value over a stated number of years.
Plain-English definition: CAGR is the constant compounded yearly rate that would connect a beginning value with an ending value over a stated number of years.[1]
How the term is used
CAGR turns a beginning value, an ending value, and an elapsed number of years into one compounded annual rate. The calculation uses the endpoints rather than listing each year's return.[1]
What to check before relying on it
Use exact dates and a consistent return basis. Contributions, withdrawals, distributions, and periods shorter than a full year require methods that match the question being asked.
Example
Growing from $100 to $121 over two years produces a 10% CAGR, even if the first year's return was far above 10% and the second year's was below it.
