CAGR Calculator

CAGR Calculator finds the compound annual growth rate between a beginning value and an ending value over a period of years and months. It handles growth and decline, treats months as fractions of a year, and shows the growth multiple and total change. It assumes no deposits or withdrawals during the period. Educational estimate only — not financial advice.

CAGR expresses growth over several years as one smoothed yearly rate, which makes outcomes over different time periods easier to compare than a simple total percentage.

1. Choose a currency symbol (display only).
2. Enter the beginning value and ending value.
3. Enter the duration in years and, optionally, months.
4. Press Calculate CAGR.
5. Read the rate, multiple and total change, then copy or download the summary.

• CAGR = (ending ÷ beginning)^(1 ÷ years) − 1
• Months converted to fractional years
• Negative CAGR for declining values
• Growth multiple and total percentage change
• Step-by-step working and clear assumptions
• Summary includes inputs, formula and disclaimer

• Use values taken at the start and end of the same period.
• Do not use CAGR when money was added or withdrawn during the period.
• Remember CAGR smooths out ups and downs; actual yearly results vary.
• Compare CAGRs only over similar lengths of time where possible.
