Guide and interpretation
Formula
Net return = return value - investment cost. ROI = net return / investment cost.
How to interpret it
Positive ROI means the return is higher than cost. Compare ROI with risk, time horizon and alternatives.
Common mistakes
Do not compare a one-month ROI with a multi-year ROI without annualizing or naming the time period.
Limits
The result excludes risk, taxes, financing cost, inflation and opportunity cost unless those are included in the inputs.
