How to use it
- Enter the beginning value of your investment.
- Enter the ending value after the period.
- Enter the number of years the investment was held.
- Read the single percentage result as your CAGR.
The CAGR Calculator tells you the average annual return that turns a starting amount into an ending amount over a set number of years, assuming growth compounds each year. Knowing the CAGR lets you compare investments, evaluate business performance, or benchmark personal savings without guessing. You simply enter the beginning value, the ending value, and the years you held the asset; the tool instantly returns a single percentage. That percentage represents the steady growth rate required to move from the first figure to the last. Use it to see if a portfolio met expectations, to pitch realistic forecasts, or to decide whether a new opportunity beats your historical returns. You can also experiment by adjusting one input to see how the rate changes, which helps you set realistic targets for future projects.
Pro tips
- Double-check that the beginning value is the amount at the start of the period, not an interim figure.
- Round the result to two decimal places for clear communication.
- Enter years as whole numbers; if you have months, convert them to a fraction of a year first.
- Avoid mixing currencies; both values must be in the same monetary unit.
Real-life examples
- An investor wants to know the annual return of a stock bought five years ago.
- A startup founder compares the growth of monthly recurring revenue over three years.
- A personal finance blogger shows readers the compounded growth of a retirement account over 20 years.
Case study
Sarah entered a $10,000 initial investment, $18,000 after 4 years, and got a 14.5% CAGR. Seeing the steady rate helped her decide to keep the fund, negotiate a better fee, and set a realistic target for her next investment.
