How Much House Can I Afford

Determine the maximum home price you can afford based on your income, existing debts, down payment, and current interest rates. This calculator uses standard lender guidelines to show you a realistic price range.

The home affordability calculator works backward from your income and debts to determine the maximum mortgage payment you can handle, then converts that payment into a home price. Lenders use the debt-to-income ratio (DTI) as the primary measure of what you can afford. The DTI compares your total monthly debt payments, including your future mortgage, to your gross monthly income. Most conventional lenders prefer a total DTI of 36 percent, though some will allow up to 43 or even 50 percent with strong compensating factors like a high credit score or large cash reserves. The calculator first takes your annual income and divides by 12 to get gross monthly income. It then multiplies by your target DTI ratio to determine the maximum total monthly debt you can carry. Subtracting your existing monthly debts (car payments, student loans, credit card minimums, and other obligations) leaves the maximum amount available for your housing payment. From that housing payment budget, the calculator subtracts estimated monthly property taxes and homeowners insurance to isolate the amount available for principal and interest. Using the standard amortization formula in reverse with your interest rate and loan term, it solves for the maximum loan amount that fits within that P&I budget. Finally, the calculator adds your down payment to the maximum loan amount to arrive at the maximum home price. If your down payment is less than 20 percent, PMI is factored into the housing payment estimate, which reduces the loan amount you qualify for slightly. Remember that the maximum price a lender will approve is not necessarily the amount you should spend. Leaving room in your budget for savings, maintenance, and unexpected expenses is important for long-term financial health.

Lenders look at your gross income, but your budget should be based on net income after taxes, retirement contributions, and insurance premiums. A home that consumes 36 percent of your gross pay could easily take 50 percent or more of your take-home pay. Run the numbers with your actual monthly cash flow to make sure you can comfortably cover the payment alongside your other living expenses.

Paying down existing debts before applying for a mortgage can significantly increase how much house you qualify for. Every dollar you eliminate from monthly obligations is a dollar that can go toward your housing payment. For example, paying off a $400 monthly car payment could increase your maximum home price by $60,000 or more, depending on your interest rate and loan term.

Your target DTI ratio should reflect your lifestyle and financial goals, not just the maximum a lender will allow. If you value travel, dining out, or early retirement savings, aim for a DTI of 28 to 30 percent rather than stretching to 36 or beyond. A conservative DTI gives you breathing room for home maintenance costs, which typically run 1 to 2 percent of the home value annually.

Consider how your income might change over the next several years when choosing a price range. If you expect a promotion or career change, you may be comfortable stretching slightly. If your income is variable, seasonal, or commission-based, use your lowest recent year as the baseline rather than your best year to avoid overextending yourself.

Do not forget to factor in the full cost of homeownership beyond the mortgage payment. Property taxes, insurance, HOA fees, utilities, lawn care, and ongoing maintenance can add 30 to 50 percent on top of your principal and interest payment. Budget for these expenses before committing to a purchase price.

Most conventional lenders prefer a total DTI of 36 percent or less, though many will approve loans up to 43 percent. FHA loans may allow DTIs up to 50 percent with strong compensating factors. The front-end ratio, which includes only housing costs, is typically capped at 28 to 31 percent of gross monthly income.

Yes, a larger down payment increases your maximum home price because it reduces the loan amount needed. It can also eliminate PMI if you put down 20 percent or more, which frees up more of your monthly budget for principal and interest. This means you may qualify for a higher purchase price with the same income.

Financial advisors generally recommend buying below your maximum qualification. Lender guidelines do not account for your individual spending patterns, savings goals, or emergency fund needs. Keeping your housing costs at 25 to 30 percent of gross income leaves room for unexpected expenses, home repairs, and continued savings.

Lenders count all recurring monthly obligations including car loans, student loans, minimum credit card payments, personal loans, child support, and alimony. They do not typically count utilities, groceries, subscriptions, or insurance premiums. Your new mortgage payment including taxes, insurance, and PMI also counts toward the total DTI.

Interest rates have a major impact on affordability. A one-percentage-point increase in rate reduces your buying power by roughly 10 percent. For example, at 6 percent you might afford a $400,000 home, but at 7 percent the same monthly payment only supports about $360,000. Locking in a lower rate significantly expands your options.
