Calculation steps
- 1Profit = final − cost = 130,000.00 − 100,000.00 = 30,000.00
- 2ROI = profit ÷ cost = 30.00%
- 3Annualized = (final ÷ cost)^(1/3) − 1 = 9.14%
- 4Rule of 72: 72 ÷ 9.14 ≈ 7.9 years to double
Typical annualized returns by asset
| Asset | Long-run annualized |
|---|---|
| Demand deposit | 0.2% |
| Money market fund | 1.5%–2% |
| Bond fund | 2%–4% |
| CSI 300 (long horizon) | 7%–9% |
| US S&P 500 (long horizon) | 7%–10% |
ROI ignores time — 50% over 1 year is far better than 50% over 10 years. Always compare investments by annualized return, and remember risk: higher expected return always comes with higher volatility.
