Average Return Calculator
Calculate the arithmetic and geometric average return on an investment over multiple periods.
Arithmetic vs Geometric
The arithmetic average is a simple mean of returns. The geometric average (CAGR) accounts for compounding and is the more accurate measure of actual performance.
What is Average Return Calculator?
An average return calculator computes the mean return of an investment over multiple periods — either the simple arithmetic average or the compounded geometric average.
The geometric average (CAGR-style) is more accurate for investments because it accounts for compounding.
How does the Average Return Calculator work?
The geometric average is computed as ((1+R1) × (1+R2) × … × (1+Rn))^(1/n) – 1.
The calculator shows both, highlighting how volatility drags the geometric average below the arithmetic one.
How to use the Average Return Calculator?
- Enter the return for each period (e.g. each year).
- The calculator shows the arithmetic and geometric average returns.

- Compare a few scenarios (conservative, moderate, aggressive) before making a decision.
Frequently Asked Questions
Which average should I use?
For investment returns, use the geometric average — it reflects the actual compounded growth of your money.
Why is the geometric average lower?
Volatility reduces compounded growth. A 50% gain followed by a 50% loss leaves you down 25%, not back to even.
Planning your finances is easier when you can see the numbers clearly. Use this calculator regularly to stay on top of your goals and make informed decisions.
