Method

Compound annual growth rate is the constant annual rate that would connect the beginning value to the ending value over the specified number of years. The calculator uses CAGR = (ending ÷ beginning)^(1 ÷ years) − 1, then also reports the total endpoint percentage change and the ending-to-beginning multiple.

Worked example

When this is useful

CAGR is useful for comparing endpoint growth rates across periods of different lengths, summarizing business metrics, and describing historical growth in a compact annualized form.

Privacy

Values are processed locally in the browser and are not sent to a financial data service.

Limitations

CAGR smooths the path between two endpoints. It does not show interim volatility, timing of cash flows, risk, taxes, fees, inflation, or future performance. The output is an arithmetic description of the values entered, not personalized financial advice.

FAQ

Does CAGR show volatility?

No. CAGR compresses the change between two endpoints into one constant annualized rate and hides the path taken between those endpoints.

Is CAGR a forecast?

No. This calculator describes the inputs you provide. It does not predict future growth or investment performance.
