Formulas Used in the Investment Home Calculator

To provide meaningful investment insights, the calculator uses the following formulas:

1. Monthly Mortgage Payment
M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)
Where:

  • M = monthly payment
  • P = loan amount (purchase price – down payment)
  • r = monthly interest rate
  • n = total number of payments (term in months)

2. Net Monthly Cash Flow
Cash Flow = Monthly Rental Income - (Mortgage Payment + Operating Expenses)

3. Annual ROI (%)
ROI = (Net Annual Income / Total Investment) * 100
Total Investment = Down Payment + Closing Costs + Renovations (if any)

4. Capitalization Rate (Cap Rate)
Cap Rate = (Net Operating Income / Property Purchase Price) * 100
Net Operating Income = Rental Income – Operating Expenses

These formulas help investors assess risk, profitability, and potential returns accurately.

Example Calculation

Let’s walk through a basic example:

  • Property Purchase Price: $300,000
  • Down Payment: $60,000
  • Loan Term: 30 years
  • Interest Rate: 5%
  • Monthly Rental Income: $2,000
  • Monthly Expenses: $500

Step 1 – Loan Amount = $240,000
Step 2 – Monthly mortgage payment ≈ $1,288
Step 3 – Net Cash Flow = $2,000 – ($1,288 + $500) = $212
Step 4 – Annual Net Cash Flow = $2,544
Step 5 – ROI = ($2,544 / $60,000) * 100 = 4.24%

This shows a positive cash flow and a modest return on investment.
