About ROI & Investment Evaluation
Return on Investment (ROI) is a key metric for assessing the efficiency or profitability of an investment. It expresses the gain (or loss) relative to the amount invested:
ROI = (Final Value - Initial Investment) / Initial Investment × 100%
Annualized ROI (also known as Compound Annual Growth Rate, CAGR) provides a normalized return per year, making it easy to compare different investment durations:
Annualized ROI = { [Final Value / Initial Investment] 1 / Years - 1 } × 100%
- Total Return: Shows the dollar gain or loss.
- ROI (%): Shows your percentage return for the total period.
- Annualized ROI: "Smooths" your return as if it happened evenly every year, even if the growth was uneven.
Investment evaluation tips:
- Compare annualized ROI for investments of different lengths.
- Consider risks, fees, inflation, and taxes—ROI by itself does not account for these factors.
- Past ROI does not guarantee future results.
Example: If you invested $1,000, and it grows to $1,500 over 3 years, your ROI is 50%, and the annualized ROI (CAGR) is about 14.47%.
