📊 Formulas Used in the Calculator

Here are the key formulas behind the scenes:

  1. Loan Amount javaCopyEditLoan Amount = Purchase Price - Down Payment
  2. Monthly Mortgage Payment iniCopyEditM = P × (r × (1 + r)^n) / ((1 + r)^n – 1) Where:
    • M = Monthly payment
    • P = Loan amount
    • r = Monthly interest rate
    • n = Number of months
  3. Monthly Cash Flow javaCopyEditCash Flow = Rental Income - (Mortgage Payment + Monthly Expenses)
  4. Annual ROI (%) iniCopyEditROI = (Annual Cash Flow / Total Cash Invested) × 100
  5. Cap Rate (%) javaCopyEditCap Rate = (Net Operating Income / Purchase Price) × 100
  6. Gross Rental Yield (%) javaCopyEditGross Yield = (Annual Rental Income / Purchase Price) × 100

🧮 Example Calculation

Let’s break down an example:

  • Purchase Price: $250,000
  • Down Payment: $50,000
  • Loan Term: 30 years
  • Interest Rate: 6%
  • Monthly Rent: $2,000
  • Monthly Expenses: $400
  • Vacancy Rate: 5%
  • Property Management Fee: $100

Step-by-step Output:

  • Loan Amount = $200,000
  • Monthly Mortgage ≈ $1,199
  • Adjusted Rent after Vacancy = $2,000 × (1 – 0.05) = $1,900
  • Total Expenses = $1,199 + $400 + $100 = $1,699
  • Monthly Cash Flow = $1,900 – $1,699 = $201
  • Annual Cash Flow = $201 × 12 = $2,412
  • Total Cash Invested = $50,000 (Down Payment)
  • ROI = ($2,412 / $50,000) × 100 = 4.82%
  • Cap Rate = (($1,900 – $500) × 12 / $250,000) × 100 = 6.72%
  • Gross Yield = ($24,000 / $250,000) × 100 = 9.6%
