Key ROI Metrics
| Metric | What It Measures | Formula |
|---|
| Cash Flow | Monthly profit/loss | Rent - All Expenses |
| Cap Rate | Property income yield | NOI ÷ Property Value × 100 |
| Cash-on-Cash | Return on invested cash | Annual Cash Flow ÷ Cash Invested |
| Total Return | All profit sources | Cash Flow + Paydown + Appreciation |
Step 1: Calculate Gross Rental Income
Estimating Rent
| Method | How |
|---|
| Comparable rentals | Check Rentals.ca, Kijiji |
| Property managers | Ask local experts |
| 1% rule (outdated) | Rarely achievable in Canada |
Example
| Unit | Monthly Rent |
|---|
| Main unit | $2,000 |
| Basement suite | $1,200 |
| Parking | $100 |
| Gross Monthly | $3,300 |
| Gross Annual | $39,600 |
Step 2: Subtract Operating Expenses
Common Operating Expenses
| Expense | % of Rent | Monthly (on $3,300) |
|---|
| Property tax | 8-15% | ~$350 |
| Insurance | 2-4% | ~$100 |
| Maintenance | 5-10% | ~$200 |
| Vacancy | 3-8% | ~$165 |
| Property management | 0-10% | ~$0-$330 |
| Utilities (if included) | Variable | ~$0-$300 |
| Condo fees (if condo) | Variable | ~$0-$500 |
The 50% Rule (Quick Estimate)
| Rule | Calculation |
|---|
| 50% rule | Operating expenses ≈ 50% of rent |
| Net Operating Income | Gross Rent × 50% |
| Example | $39,600 × 50% = $19,800 NOI |
This rule is useful for quick screening but analyze each property.
Detailed Expense Example
| Expense | Annual |
|---|
| Property tax | $4,200 |
| Insurance | $1,200 |
| Maintenance | $2,400 |
| Vacancy (5%) | $1,980 |
| Utilities | $1,800 |
| Property management (0%) | $0 |
| Total Operating Expenses | $11,580 |
| Net Operating Income (NOI) | $28,020 |
Step 3: Calculate Cap Rate
Cap Rate = NOI ÷ Property Value × 100
Example
| Factor | Value |
|---|
| NOI | $28,020 |
| Property price | $600,000 |
| Cap Rate | 4.67% |
Canadian Cap Rates by Market
| Market | Typical Cap Rate |
|---|
| Toronto | 3-4% |
| Vancouver | 3-4% |
| Calgary | 5-6% |
| Edmonton | 5-7% |
| Ottawa | 4-5% |
| Montreal | 4-5% |
| Halifax | 5-6% |
| Smaller markets | 6-10%+ |
Higher cap rate = higher income relative to price (but often higher risk).
Step 4: Account for Mortgage
Mortgage Example
| Factor | Value |
|---|
| Purchase price | $600,000 |
| Down payment (20%) | $120,000 |
| Mortgage amount | $480,000 |
| Interest rate | 5.5% |
| Amortization | 25 years |
| Monthly payment | $2,942 |
| Annual payment | $35,304 |
Principal vs Interest (Year 1)
| Component | Annual |
|---|
| Total payment | $35,304 |
| Interest | ~$25,500 |
| Principal paydown | ~$9,800 |
Step 5: Calculate Cash Flow
Monthly Cash Flow
| Item | Monthly |
|---|
| Gross rent | $3,300 |
| - Operating expenses | -$965 |
| - Mortgage payment | -$2,942 |
| Cash Flow | -$607 |
Annual Cash Flow
| Item | Annual |
|---|
| NOI | $28,020 |
| - Mortgage payment | -$35,304 |
| Cash Flow | -$7,284 |
This property is cash-flow negative (common in Canadian markets).
Step 6: Calculate Cash-on-Cash Return
Total Cash Invested
| Investment | Amount |
|---|
| Down payment | $120,000 |
| Closing costs | $12,000 |
| Immediate repairs | $5,000 |
| Total Cash Invested | $137,000 |
Cash-on-Cash = Annual Cash Flow ÷ Total Cash Invested × 100
| Factor | Value |
|---|
| Annual cash flow | -$7,284 |
| Cash invested | $137,000 |
| Cash-on-Cash | -5.3% |
Negative cash-on-cash means you’re paying to hold the property.
Step 7: Calculate Total Return
Wealth Building Components
| Component | Annual |
|---|
| Cash flow | -$7,284 |
| Mortgage principal paydown | +$9,800 |
| Appreciation (3%) | +$18,000 |
| Total Return | +$20,516 |
Total Return on Cash
| Factor | Value |
|---|
| Total return | $20,516 |
| Cash invested | $137,000 |
| Total ROI | 15.0% |
Despite negative cash flow, total return is positive due to appreciation and mortgage paydown.
ROI Scenarios
Scenario Comparison
| Scenario | Cash Flow | Principal | Appreciation | Total ROI |

| Balanced market | $0 | $10,000 | $12,000 | 16.1% |
Toronto/Vancouver have poor cash flow but higher appreciation potential.
