Average Return Calculator

Calculate arithmetic mean return, geometric mean (CAGR), and annualized return from a series of annual returns.

Using the Average Return Calculator

A successful investor knows the difference between a simple average and the "True" annualized return. This tool calculates the Compound Annual Growth Rate (CAGR) and geometric mean of your portfolio, accounting for the volatility that simple arithmetic means often hide.

How it Works

1
Enter the starting and ending values of your investment.
2
Input the number of years or months elapsed.
3
Review the calculated CAGR—the standard for fund performance.
4
Compare the arithmetic average vs. the geometric mean.

Enter annual returns (%) for each year, one per row. Add as many years as needed.
