Is 36% DTI conservative?

Yes — the federal Qualified Mortgage rule allows up to 43%, and FHA loans up to 50%. 36% is the historical "safe" target; 28% is even safer.

Should I use my max approval as my budget?

Almost never. Lenders approve to their tolerance, not yours. Most homeowners are happiest spending 20–30% below their max approval, leaving room for life.

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.
