Estimates only. Your actual numbers depend on your loan, credit, and property. Guidelines vary by loan program and the full picture of your file. Many programs allow a back-end DTI around 43-50%, but lower usually means more room in your budget.

How do I read my DTI result?

The big number is your back-end DTI, which includes your housing payment plus other monthly debts as a share of your income. Below it, the front-end number shows housing alone. Lower percentages generally leave more room in your budget and can give a lender more confidence in your file.

Why does DTI matter so much?

DTI is one of the main things a lender reviews because it shows whether a new payment fits alongside your existing obligations. It works together with your credit, down payment, and reserves. A strong DTI can open up more options, while a high one may limit them. It's a number worth knowing before you shop.

Common questions

Your debt-to-income ratio, or DTI, compares your monthly debt payments to your gross monthly income. Lenders use it to gauge how much new payment you can handle. There are two versions: front-end looks at housing only, and back-end includes all your monthly debts plus the housing payment.

It varies by loan program and the rest of your file, so there's no single cutoff. Many programs allow a back-end DTI somewhere around 43% to 50%, and strong credit or reserves can give more flexibility. A lower DTI usually means more breathing room in your monthly budget.

You can lower your DTI by paying down or paying off monthly debts, avoiding new loans before you buy, or increasing your qualifying income. Even removing one small monthly payment can help. If your DTI is tight, we can map out which moves would help your numbers the most.
