Frequently Asked Questions
What is the ROI formula?↓
ROI = ((Final Value − Initial Investment) / Initial Investment) × 100. For example, invest $10,000, get back $13,500: ROI = (3,500/10,000) × 100 = 35%.
What is CAGR (annualized ROI)?↓
CAGR = (Final Value / Initial Value)^(1/years) − 1. It is the constant annual growth rate that would produce the same final value. More useful than total ROI for comparing investments of different durations.
What is a good ROI?↓
It depends on the investment type and risk. The S&P 500 historically returns ~7-10% annually (CAGR). Real estate averages ~8-12%. A higher ROI is better, but must be weighed against risk and time horizon.
How is ROI different from profit margin?↓
ROI measures return relative to the cost of the investment. Profit margin measures profit as a percentage of revenue. ROI is used for investment decisions; profit margin for business performance.
