Return on Investment (ROI) is a fundamental metric for evaluating investment performance. Understanding how to calculate and interpret ROI helps investors make informed decisions.
What Is ROI?
Definition
ROI measures the gain or loss generated on an investment relative to the amount invested.
Basic Formula
ROI = (Net Profit / Total Investment) × 100
Example
- Investment: $100,000
- Net Profit: $20,000
- ROI = ($20,000 / $100,000) × 100 = 20%
ROI in Real Estate
Components
- Purchase price
- Renovation costs
- Holding costs
- Transaction costs
- Sale price
Calculation
Total Investment = Purchase + Renovation + Holding + Transaction Costs Net Profit = Sale Price - Total Investment ROI = Net Profit / Total Investment
Annualized ROI
Why It Matters
Comparing investments with different timelines requires annualization.
Formula
Annualized ROI = (1 + ROI)^(1/years) - 1
Example
- 20% ROI over 6 months
- Annualized = (1.20)^2 - 1 = 44%
