Frequently Asked Questions

What is the difference between arithmetic and geometric return?

Arithmetic return is the simple average. Geometric return (CAGR) accounts for compounding and is usually lower and more accurate for measuring actual portfolio growth.

Why does geometric return matter?

Because investment returns compound over time. A 50% gain followed by a 50% loss does not break even; the geometric return captures this effect.

What is standard deviation in this context?

It measures the volatility or dispersion of annual returns around the average. Higher standard deviation means higher risk.

Can I use negative returns?

Yes. Enter negative values for down years just like positive values for up years.
