ROI: The Universal Investment Metric
Return on Investment (ROI) measures how much profit you made relative to how much you invested. It's the most basic — and most important — metric for comparing any investment, including real estate.
The formula is simple:
ROI = (Net Profit / Total Investment) x 100%
ROI on a Rental Property
Let's work through a Malaysian example:
- Purchase price: RM 500,000
- Closing costs (stamp duty, legal fees, etc.): RM 25,000
- Renovation: RM 30,000
- Total Investment: RM 555,000
After 5 years:
- Total rental income received: RM 180,000 (RM 3,000/month x 60 months)
- Total expenses (maintenance, repairs, management): RM 45,000
- Property sold for: RM 620,000
- Total Returns: RM 620,000 + RM 180,000 - RM 45,000 = RM 755,000
- Net Profit: RM 755,000 - RM 555,000 = RM 200,000
ROI = (RM 200,000 / RM 555,000) x 100% = 36%
That's 36% over 5 years, or approximately 7.2% per year (simple, not compounded).
Annualized ROI
To compare investments of different durations, use annualized ROI:
Annualized ROI = ROI / Number of Years
This is a simplified version. For the above example: 36% / 5 = 7.2% per year.
Comparing Two Deals
| Metric | Deal A (Cheras Condo) | Deal B (Cyberjaya Apartment) |
|---|---|---|
| Total Investment | RM 555,000 | RM 320,000 |
| Net Profit (3 years) | RM 95,000 | RM 72,000 |
| ROI | 17.1% | 22.5% |
| Annualized ROI | 5.7% | 7.5% |
Deal B has a higher ROI despite lower absolute profit. This is why ROI matters — it normalizes returns relative to the amount invested, so you can compare deals of different sizes.
Important Limitations
- Basic ROI doesn't account for the time value of money
- It doesn't reflect financing — a leveraged deal looks very different
- Always include ALL costs: stamp duty, legal fees, renovation, agent commissions
