What Is a Good Debt-to-Income Ratio for a Mortgage?

A good debt-to-income ratio for a mortgage is generally 36% or below, but most loan programs approve well above that, up to 50% through automated underwriting on conventional loans. "Good" depends on whether you mean comfortable or qualifying, and those are two different numbers.

How DTI is calculated

Your debt-to-income ratio is your total monthly debt payments divided by your gross monthly income. Lenders look at two versions: the front-end ratio (just your housing payment) and the back-end ratio (housing plus all other debts, car loans, student loans, credit card minimums). The back-end ratio is the one that matters most for qualifying. Utilities, groceries, and other non-debt expenses don't count.

What counts as "good"

A back-end DTI of 36% or below is widely considered comfortable, it leaves real room in your budget. But comfortable and qualifying aren't the same thing. As our guide to DTI limits explains, conventional loans routinely approve up to 45%, and up to 50% through automated underwriting with strong compensating factors. FHA can go into the high 40s and beyond, and VA has no hard cap at all, using a residual-income test instead.

The number that actually determines your approval

So if you're asking "is my DTI good enough to qualify," the answer is usually more forgiving than the 36% rule suggests. A borrower at 44% often qualifies comfortably through automated underwriting. The 36% figure is a budgeting benchmark, not the qualifying ceiling. Knowing this matters, plenty of would-be buyers talk themselves out of applying because they assume 36% is a hard limit when their real affordability picture has more room.

How to improve your DTI

If your DTI is higher than you'd like, two levers move it: reduce your monthly debt (paying off a car loan or credit card removes that payment from the calculation entirely) or increase your qualifying income. Paying down a small loan balance to eliminate its monthly payment often does more for your DTI than the balance size would suggest, because it's the monthly payment, not the total debt, that counts.

Why a lower DTI still helps even when you qualify

Even if you qualify at a higher DTI, a lower one strengthens your whole application and can help with pricing. It also leaves you breathing room for the unexpected. So while you don't need to hit 36% to get approved, getting closer to it makes you a stronger borrower and a more comfortable homeowner.
