Enter the holding period in years. The calculator shows your total ROI percentage, net profit, annualized ROI (CAGR), and investment multiple (how many times your money grew).
James bought a rental property for $200,000, spent $20,000 on renovations, and sold it 4 years later for $310,000. Total cost = $220,000. Net profit = $310,000 − $220,000 = $90,000. ROI = ($90,000 / $220,000) × 100 = 40.9%. Annualized ROI = (1.409^(1/4) − 1) × 100 = 8.97% per year. Investment multiple: 1.41× — James turned every dollar into $1.41.
| METRIC | FORMULA | NOTES |
|---|---|---|
| Net Profit | Final Value − Total Cost | Can be negative (a loss) |
| ROI | (Net Profit / Total Cost) × 100 | Total return as a percentage |
| Annualized ROI | ((1 + ROI/100)^(1/years) − 1) × 100 | Also known as CAGR |
| Multiple (MoM) | Final Value / Total Cost | 2× = doubled, 0.5× = lost half |
