About this tool

How much house you can afford comes down to one ratio: your debt-to-income (DTI). Lenders usually want all your monthly debt — including the new mortgage — to stay under 36% of your gross monthly income, with hard caps around 43–50%. This calculator works backwards: given your income, existing debts, down payment, and the current rate, what's the largest home price that keeps you under that ceiling? It includes a realistic PITI estimate (taxes, insurance) instead of just the bare loan, so the answer matches what a lender will actually approve.

Frequently asked

That's how lenders calculate it. They use your gross income because they want consistency across borrowers regardless of state tax or 401(k) contributions.
