Calculate how much house you can afford based on your income, down payment, and monthly expenses. Get personalized home buying guidance.
Your monthly housing payment should not exceed 28% of your gross monthly income.
Determining how much house you can afford is the most important step before starting your home search. Buying more house than you can comfortably afford leads to financial stress and can derail other life goals. Our house affordability calculator analyzes your income, debts, down payment, and other factors to give you a realistic home buying budget.
The traditional 28/36 rule states that your monthly housing costs (mortgage, taxes, insurance) should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36% of gross income. For example, with a gross monthly income of 100,000 (in your local currency), your maximum housing payment should be 28,000 and total debt payments 36,000 in the same currency.
Beyond the mortgage payment, budget for property taxes, home insurance, maintenance (plan 1-2% of home value annually), HOA fees if applicable, utilities, and major repairs. These costs often add 25-30% on top of your mortgage payment. Our home affordability calculator helps you account for these additional costs.
Save a larger down payment to reduce the loan amount. Improve your credit score before applying to qualify for better rates. Pay off existing debts to lower your debt-to-income ratio. Consider a longer loan term to lower monthly payments (though total interest will be higher). Look at less expensive neighborhoods or properties that need renovation.
Mortgage lenders and financial advisors commonly reference debt-to-income ratio guidelines when evaluating home affordability — a frequently cited rule of thumb suggests total housing costs (mortgage, property tax, insurance) shouldn't exceed roughly 28% of gross monthly income, and total debt payments including housing shouldn't exceed roughly 36%. These guidelines offer a useful starting framework, though actual affordability also depends heavily on other financial obligations, savings goals, and regional cost-of-living factors that a simple ratio doesn't fully capture.
Home affordability calculations need to account for more than just principal and interest — property taxes, homeowners insurance, private mortgage insurance (if applicable), and homeowners association fees all add to the true monthly housing cost, and overlooking these additional costs is a common reason first-time buyers underestimate their actual affordable price range.
Mortgage lenders often approve buyers for a loan amount at the upper edge of what debt-to-income guidelines technically allow, but the maximum approved amount and a genuinely comfortable monthly payment, leaving room for savings, emergencies, and lifestyle flexibility, are frequently two different numbers. Calculating affordability based on personal comfort and existing financial goals, rather than simply the maximum a lender is willing to approve, tends to produce a more sustainable long-term homeownership experience.
The 28/36 rule states that your housing payment (PITI) should not exceed 28% of your gross monthly income, and your total debt payments (including housing) should not exceed 36% of your gross monthly income. This is a conservative guideline for home buying.
Traditional wisdom suggests 20% down to avoid PMI. However, many programs allow 3-5% down. A larger down payment reduces your monthly payment and total interest, but requires more cash upfront. Consider your savings and monthly budget.
No, just because you can afford the maximum doesn't mean you should. Consider your lifestyle, other financial goals, emergency fund, and comfort level. Many people choose to buy below their maximum for financial flexibility.
Beyond the mortgage, consider: closing costs (2-5% of home price), moving expenses, furniture, repairs, utilities, and maintenance. Build an emergency fund for unexpected home repairs.
High debt-to-income ratio reduces the amount you can borrow. Lenders typically want total debt payments (including mortgage) below 36% of income. Paying down debt before house hunting can increase your purchasing power.
