Example: How a Property Rent Calculator Works
Let’s look at a practical example:
Property Details:
- Purchase Price: $250,000
- Down Payment: $50,000
- Loan Amount: $200,000
- Interest Rate: 5%
- Monthly Rent: $2,000
- Monthly Expenses: $600
- Vacancy Rate: 5%
Step 1: Annual Rental Income
$2,000 × 12 = $24,000
Minus 5% vacancy = $22,800
Step 2: Annual Expenses
$600 × 12 = $7,200
Step 3: Net Annual Income
$22,800 – $7,200 = $15,600
Step 4: ROI Calculation
ROI = (Net Income ÷ Total Investment) × 100
= ($15,600 ÷ $50,000) × 100 = 31.2% ROI
✅ Result: This property provides excellent cash flow and a strong ROI — a green light for investors.
