Rent vs. Buy Calculator

The Rent vs. Buy Calculator is a tool designed to help you assess the financial implications of renting compared to buying a home. By entering important details about your financial situation, expected costs, and market assumptions, you can find out which option might be more financially beneficial over time.

Key Formula Used

Monthly Mortgage Payment Formula:

\( M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1} \)

Where:

  • \( M \): Monthly mortgage payment
  • \( P \): Loan principal (home price minus down payment)
  • \( r \): Monthly interest rate (annual rate divided by 12)
  • \( n \): Total number of payments (loan term in years multiplied by 12)
