How It Works

ROI is useful for clear, fast reporting of profitability on a completed investment.

Because ROI is not time-normalized, it can overstate attractiveness for long-duration projects.

Pair ROI with CAGR when evaluating options with different holding periods.

Scenario

Investment grows from $20,000 to $26,000.

Outcome

ROI is 30% total return over that full period.

Scenario

Another investment also returns 30% but over twice the duration.

Outcome

ROI alone hides that annualized efficiency is lower.

ROI vs CAGR: Which Metric Should You Use?

Compare ROI and CAGR for total-return versus annualized-return interpretation.

Can ROI be negative?

Yes. If final value is below initial cost, ROI is negative.

Should ROI be used for long-term ranking?

Use it with CAGR and risk context for better ranking quality.
