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
