Free Average Return Calculator - Analyze Investment Performance
Calculate arithmetic mean, geometric mean, and compound annual growth rate (CAGR) for accurate investment performance analysis.
Quick Answer
To calculate average investment return, use geometric mean (CAGR) rather than arithmetic mean for accuracy. CAGR = (Ending Value / Beginning Value)^(1/years) - 1. Our free calculator at practicalwebtools.com computes both metrics to help you accurately assess investment performance.
Key Facts about Average Return Calculator:

Frequently Asked Questions
Everything you need to know about our average return calculator
Why use geometric mean instead of arithmetic?
Geometric mean reflects actual compounding - arithmetic mean overstates returns.
Geometric mean accounts for compounding. A 50% gain followed by 50% loss gives arithmetic mean of 0% but geometric mean of -13.4%, which reflects actual 25% loss.
What is CAGR?
The constant annual return needed to grow from beginning to ending value.
Compound Annual Growth Rate is the constant annual return that would take an investment from its beginning to ending value. It is the geometric mean of annual returns.
How do I calculate average return?
Use CAGR formula or our calculator for accurate investment returns.
For accurate investment returns, use CAGR: (Ending Value / Beginning Value)^(1/years) - 1. Our calculator computes this automatically.
