About This Tool

### About the Home Affordability Calculator Buying a home is one of the largest financial decisions most people will ever make, and knowing exactly how much house you can afford is the critical first step. This free home affordability calculator uses the widely accepted 28/36 debt-to-income rule that mortgage lenders rely on to determine your maximum home purchase price. The 28/36 rule states that your total housing costs -- including mortgage principal and interest, property taxes, homeowners insurance, and HOA fees -- should not exceed 28% of your gross monthly income (the front-end ratio). Additionally, your total monthly debt obligations, including housing costs plus car payments, student loans, credit card minimums, and other debts, should not exceed 36% of your gross monthly income (the back-end ratio). This calculator factors in all the key variables that lenders consider: your annual gross income, existing monthly debt payments, available down payment, current mortgage interest rates, property taxes, and homeowners insurance. It then calculates the maximum loan amount you can qualify for and adds your down payment to determine the highest home price within your budget. Visual debt-to-income ratio gauges help you instantly see where you stand relative to lender guidelines, making it easy to understand your borrowing capacity at a glance.

Frequently Asked Questions

What is the 28/36 rule for home affordability?

The 28/36 rule is a guideline used by most mortgage lenders to determine how much a borrower can afford. The first number (28%) means your total housing costs -- mortgage payment, property taxes, insurance, and HOA fees -- should not exceed 28% of your gross monthly income. The second number (36%) means your total monthly debt payments, including housing costs plus all other debts like car loans and credit cards, should not exceed 36% of your gross monthly income. Some loan programs allow higher ratios, but 28/36 is the standard benchmark.

How does my down payment affect how much home I can afford?

Your down payment directly increases the maximum home price you can afford without changing your monthly payment. For example, if you qualify for a $240,000 mortgage and have a $60,000 down payment, you can afford a $300,000 home. A larger down payment also eliminates the need for private mortgage insurance (PMI) if you put down 20% or more, which further reduces your monthly costs and can allow you to qualify for a higher purchase price.

Should I buy the maximum amount I can afford?

Financial advisors generally recommend buying below your maximum affordability limit. The 28/36 rule represents the upper boundary of what lenders will approve, not necessarily what is comfortable for your lifestyle. Consider leaving room in your budget for home maintenance (typically 1-2% of home value annually), savings goals, retirement contributions, and unexpected expenses. Many experts suggest keeping your housing costs at or below 25% of your take-home pay for a more comfortable financial situation.
