How to Use the Real Estate Investment Calculator

Using the Real Estate Investment Calculator is simple and efficient. You’ll need to gather a few basic property and financial details before getting started. Follow these steps:

Step-by-Step Instructions:

  1. Enter the Property Purchase Price
    This is the price at which you intend to buy the property.
  2. Input the Down Payment Amount or Percentage
    Specify how much you plan to pay upfront. This influences your loan amount.
  3. Fill in Loan Terms
    Include the interest rate and loan term in years to calculate monthly mortgage payments.
  4. Estimate Monthly Rental Income
    Enter how much you expect to receive in rent per month.
  5. Input Monthly Operating Expenses
    This includes property management, insurance, taxes, maintenance, and HOA fees.
  6. Add One-Time Costs
    Include closing costs, renovations, or any other upfront investments.
  7. Review Your Investment Summary
    The calculator will display key metrics:
    • Monthly Cash Flow
    • Annual Cash Flow
    • ROI (Return on Investment)
    • Cap Rate
    • Net Operating Income (NOI)
    • Total Return over the holding period

Real Estate Investment Formulas Used

Our calculator uses industry-standard financial formulas to provide an accurate outlook:

  1. Monthly Mortgage Payment
    = P × r × (1 + r)^n / ((1 + r)^n – 1)
    Where P = loan amount, r = monthly interest rate, n = total number of payments
  2. Cash Flow
    = Monthly Rental Income – Monthly Expenses – Monthly Mortgage Payment
  3. Cap Rate (Capitalization Rate)
    = (Net Operating Income ÷ Property Value) × 100
  4. Net Operating Income (NOI)
    = Annual Rental Income – Annual Operating Expenses
  5. Cash-on-Cash ROI
    = (Annual Cash Flow ÷ Total Cash Invested) × 100
  6. Total Return
    = Cash Flow + Appreciation + Principal Paydown – Costs

Example Calculation

Let’s assume the following scenario:

  • Property Price: $250,000
  • Down Payment: 20% ($50,000)
  • Loan Term: 30 years
  • Interest Rate: 6%
  • Monthly Rent: $2,000
  • Monthly Expenses: $500
  • One-Time Costs: $10,000

Results:

  • Monthly Mortgage Payment: $1,199
  • Cash Flow: $2,000 – $500 – $1,199 = $301
  • Annual Cash Flow: $3,612
  • NOI: ($2,000 – $500) × 12 = $18,000
  • Cap Rate: ($18,000 ÷ $250,000) × 100 = 7.2%
  • Cash-on-Cash ROI: ($3,612 ÷ $60,000) × 100 = 6.02%
