What ROI can—and cannot—show
ROI summarizes gain or loss relative to cost. Annualized return makes holding periods easier to compare, but neither measure describes volatility, liquidity, taxes or the risk taken to earn the result.

ROI calculator questions
What is a good ROI?
There is no universal target. A return should be evaluated against its time period, risk, liquidity, taxes, fees and realistic alternatives.
Why annualize a return?
Annualizing converts a multi-year result into an equivalent yearly rate, making different holding periods easier to compare.
