Home Mortgage Affordability Calculator

Introduction: Deciding on a home mortgage involves careful consideration of your financial situation. Our Home Mortgage Affordability Calculator is designed to assist you in determining the mortgage amount you can comfortably afford based on your annual income, monthly expenses, and selected loan parameters. By understanding your financial limits, you can make informed decisions when exploring home-buying options.

Formula: The calculator uses a simplified version of the mortgage affordability formula. It calculates the affordable home mortgage amount based on the annual income, subtracting the total annual expenses and applying the mortgage payment formula. This ensures that the resulting mortgage is within your financial means.

How to Use:

  1. Enter your annual income in the “Annual Income” field.
  2. Input your monthly expenses in the “Monthly Expenses” field.
  3. Specify the interest rate in the “Interest Rate (%)” field.
  4. Set the desired loan term in years in the “Loan Term” field.
  5. Click the “Calculate” button to obtain your affordable home mortgage amount.

Example: If your annual income is $80,000, monthly expenses total $1,000, the interest rate is 3.5%, and the loan term is 30 years, the calculated affordable home mortgage amount would be $314,704.20.
