How Much House Can You Really Afford?

Buying a home is exciting, but it's crucial to distinguish between what the bank says you can afford and what your budget allows. This House Affordability Calculator uses industry-standard Debt-to-Income (DTI) ratios to estimate a realistic home buying budget that won't leave you "house poor."

The Golden Rules of Affordability (DTI)

Lenders look at two main ratios when approving a mortgage:

  1. Front-End Ratio (Housing Ratio): Ideally, your monthly housing expenses (Principal, Interest, Taxes, Insurance) should not exceed 28% of your gross monthly income.
  2. Back-End Ratio (Total Debt Ratio): Your total monthly debt payments (Housing + Cars + Credit Cards + Student Loans) should not exceed 36% (Conservative) to 43% (Standard) of your gross monthly income.
How we calculate: This tool calculates the maximum payment allowed by both rules and uses the lower of the two to ensure you stay within safe limits.

Key Factors Affecting Your Budget

Down Payment
The cash you pay upfront. A larger down payment reduces your loan amount and monthly payment, allowing you to afford a more expensive home.
Interest Rate
Even a 1% increase in rates can significantly reduce your buying power. Always check current rates.
Monthly Debts
High car payments or credit card bills eat into your DTI ratio. Paying off debt is often the fastest way to increase your home buying budget.

Example Calculation

Suppose you earn $85,000/year (~$7,083/month) and have $500 in monthly debt.

  • 28% Rule: Max housing payment = $1,983.
  • 36% Rule: Max total debt = $2,550. Subtracting $500 debt leaves $2,050 for housing.
  • Result: The lower number is $1,983. After deducting taxes/insurance, the remaining amount determines your loan size.
