Lenders qualify you using debt-to-income (DTI) ratios: your total monthly debts, including the new mortgage, shouldn't exceed a set share of your gross income. Adjust the ratio to see conservative vs. maximum budgets.

How the debt-to-income ratio works

Most conventional lenders cap your total monthly debt — including the new house payment, car loans, student loans, and minimum credit card payments — at around 36% of gross monthly income, though some programs allow up to 43-50% for well-qualified borrowers. This calculator works backward from your chosen ratio to find the housing payment you can support, then solves for the home price that produces that payment.

Once you have a target price, run it through the mortgage calculator for a full payment breakdown, or the closing costs estimator to check you have enough cash for settlement on top of your down payment.
