How to Use the Real Estate Deal Calculator

Using a Real Estate Deal Calculator is simple, provided you have the necessary financial details on hand. Here’s a step-by-step guide:

  1. Enter Purchase Price: The amount you plan to pay for the property.

    • Loan term (in years)
  4. Add Rental Income: Expected monthly or annual rental income.

    • ROI
    • Total profit over a chosen time frame

Real Estate Deal Analysis Formulas

The calculator uses standard real estate formulas, as outlined below:

  1. Monthly Loan Payment:
    Loan Payment = (Loan Amount × Interest Rate) / [1 – (1 + Interest Rate)^-Loan Term in months]
  2. Annual Gross Rental Income:
    Gross Income = Monthly Rent × 12
  3. Annual Operating Expenses:
    Total Expenses = Property Taxes + Insurance + Maintenance + Management + Vacancy Loss
  4. Net Operating Income (NOI):
    NOI = Gross Rental Income – Operating Expenses
  5. Cap Rate:
    Cap Rate = (NOI ÷ Purchase Price) × 100
  6. Cash Flow:
    Monthly Cash Flow = Gross Rental Income – (Monthly Loan Payment + Monthly Expenses)
  7. ROI (Return on Investment):
    ROI = (Annual Cash Flow ÷ Initial Cash Investment) × 100

Example Calculation

Let’s walk through an example:

  • Purchase Price: $250,000
  • Down Payment: $50,000
  • Loan Term: 30 years
  • Interest Rate: 5%
  • Monthly Rent: $2,000
  • Annual Expenses: $6,000

Step-by-Step:

  1. Loan Amount = $250,000 – $50,000 = $200,000
  2. Monthly Loan Payment ≈ $1,074
  3. Annual Gross Income = $2,000 × 12 = $24,000
  4. NOI = $24,000 – $6,000 = $18,000
  5. Cap Rate = ($18,000 ÷ $250,000) × 100 = 7.2%
  6. Monthly Cash Flow = $2,000 – ($1,074 + $500) = $426
  7. Annual Cash Flow = $426 × 12 = $5,112
  8. ROI = ($5,112 ÷ $50,000) × 100 = 10.22%
