How to Determine How Much House You Can Afford

Figuring out how much house you can afford requires more than just looking at the purchase price. Lenders, financial advisors, and smart buyers all focus on the same core metric: your debt-to-income ratio (DTI). This is the percentage of your gross monthly income that goes toward debt payments — including your future mortgage.

The most widely used guideline is the 28/36 rule: spend no more than 28% of gross monthly income on housing costs (principal, interest, taxes, and insurance — often called PITI), and no more than 36% on all debt combined. Some lenders allow up to 43% total DTI for conventional loans, but that leaves little financial cushion.

Beyond DTI, your down payment significantly affects affordability. A larger down payment reduces your loan amount, eliminates or reduces PMI (private mortgage insurance), and lowers your monthly payment. Most conventional loans require at least 3–5% down, but 20% is the threshold to avoid PMI.

Don't forget to factor in property taxes, homeowner's insurance, and HOA fees. These costs can add hundreds of dollars per month to your payment and vary significantly by location. This calculator includes all of these to give you a realistic total monthly cost estimate.
