How the formula works
Gross Annual Rent = Monthly Rent × Units × 12 × (Occupancy / 100) | Net Income = Gross Rent − Total Expenses
- Gross Annual Rent = Monthly Rent per Unit × Number of Units × 12 × (Occupancy Rate / 100)
- Total Annual Expenses = (Management + Maintenance + Property Tax + Insurance + Mortgage) × 12
- Net Annual Income = Gross Annual Rent − Total Annual Expenses
- Monthly Cash Flow = Net Annual Income ÷ 12
- Expense Ratio = (Total Annual Expenses ÷ Gross Annual Rent) × 100
- A lower expense ratio indicates higher profitability
