ROI formulas
- ROI % = (Net Profit ÷ Cost of Investment) × 100
- Net Profit = Final Value - Cost of Investment
- Annualized ROI = ((1 + ROI)^(1/years) - 1) × 100
What is a good ROI?
It depends entirely on the asset class and timeframe. The S&P 500 has historically returned ~10% annually. Real estate averages 8–12%. Marketing campaigns often target 5:1 ROI (400% return) as a minimum viable benchmark.
ROI vs annualized ROI
A total ROI of 100% over 10 years sounds impressive, but annualised it's only ~7.2% per year. Always compare investments using annualized ROI so timeframes don't distort the comparison.
