Home Affordability Calculator

By























Buying a home is one of the biggest financial decisions you will make. Understanding how much home you can realistically afford is essential to avoid financial strain and ensure long-term comfort. The Home Affordability Calculator helps you estimate the maximum home price based on your financial profile including income, debts, down payment, interest rate, and other housing expenses.

Formula

The calculation involves several components:

  • Front-end ratio (typically 28%): The percentage of your gross monthly income that can be spent on housing costs, including mortgage, property taxes, and insurance.
  • Back-end ratio (typically 36%): The percentage of your gross monthly income that can be spent on all debts, including housing costs and other debt payments.

The calculator finds the maximum mortgage payment you can afford considering these ratios and your monthly debts, then calculates the loan amount based on mortgage formulas.

How to Use the Home Affordability Calculator

  1. Enter your annual gross income.
  2. Enter your available down payment amount.
  3. Enter the annual interest rate on the mortgage.
  4. Enter the loan term in years.
  5. Enter your monthly debt payments (credit cards, loans, etc.).
  6. Enter the property tax rate as a percentage of home value annually.
  7. Enter estimated monthly home insurance cost.
  8. Click Calculate.

You will get an estimated maximum home price you can afford and the monthly housing budget considered.

Example

If you earn $80,000 annually, have $20,000 for a down payment, an interest rate of 5%, loan term of 30 years, monthly debts of $500, property tax rate of 1.2%, and home insurance $100/month:

  • The calculator will estimate a maximum affordable home price around $350,000 (example output).
