📈 Property Rent Calculation Formula

Here are the core formulas the calculator uses:

  1. Gross Rental Income
    = Monthly Rent × 12
  2. Vacancy Adjustment
    = Gross Rental Income × (1 - Vacancy Rate)
  3. Net Operating Income (NOI)
    = Adjusted Rental Income - Annual Expenses
  4. Cap Rate (%)
    = (NOI ÷ Property Price) × 100
  5. Monthly Mortgage Payment (optional)
    = [P × r × (1 + r)^n] ÷ [(1 + r)^n - 1]
    Where:
    • P = loan amount
    • r = monthly interest rate
    • n = total number of payments
  6. Cash Flow
    = NOI - Annual Mortgage Payments

💡 Example of Property Rent Calculation

Let’s say:

  • Purchase Price: $300,000
  • Monthly Rent: $2,000
  • Annual Expenses: $5,000
  • Vacancy Rate: 5%
  • Loan Amount: $240,000 @ 4% for 30 years

Step-by-step:

  1. Gross Income: 2000 × 12 = $24,000
  2. Adjusted Income: 24000 × (1 - 0.05) = $22,800
  3. NOI: 22800 - 5000 = $17,800
  4. Cap Rate: (17800 ÷ 300000) × 100 = 5.93%
  5. Monthly Mortgage: ~$1,145
  6. Annual Mortgage: 1,145 × 12 = $13,740
  7. Cash Flow: 17,800 - 13,740 = $4,060

This property yields a positive annual cash flow of $4,060 and a Cap Rate of 5.93%, indicating it’s a viable rental investment.
