Home affordability calculator

Work out a comfortable home price from your income and debts using the time-tested 28/36 rule — not the inflated number a lender will approve.

Quick answerThe 28/36 rule caps housing at 28% of gross monthly income and total debt at 36%. This tool applies the stricter of those two limits, then converts the available payment into an estimated home price at your rate and down payment.

Why your number should beat the lender's number

Lenders today routinely approve debt-to-income ratios well above the classic 36%. That benefits the lender, not you. Anchoring to a disciplined affordability figure — and shopping below it — is how buyers avoid becoming "house poor." For the full breakdown, read how much house you can actually afford in 2026.

Frequently asked questions

How much house can I afford on my income?

A common guideline is the 28/36 rule: keep total housing costs (PITI) at or below 28% of gross monthly income, and all debt payments at or below 36%. This calculator works backward from your income and existing debts to estimate a comfortable price range at today's rates.

What is the 28/36 rule?

It's a lending guideline: spend no more than 28% of gross monthly income on housing (the 'front-end' ratio) and no more than 36% on total debt including the mortgage (the 'back-end' ratio). Many lenders now allow higher ratios, but the 28/36 rule reflects what's comfortable, not just what's approvable.

Does a lender's pre-approval tell me what I can afford?

No. A pre-approval is the maximum a lender is willing to risk lending you — a ceiling, not a target. It doesn't account for your savings goals, lifestyle, or risk tolerance. Run your own affordability number first, then shop below it.
