Debt-to-Income Ratio Explained

Debt-to-income ratio, or DTI, compares your monthly debt payments to your gross monthly income. Lenders use it to judge how much you can borrow.

How DTI is calculated

Add your future housing payment and other monthly debts, then divide by your gross monthly income. A total housing plus debt figure of $2,600 on $8,000 income is a 32.5% DTI.

What lenders look for

Many programs prefer a total DTI at or under 43%, though some allow higher with strong credit, reserves, or automated approval. Lower is better and can improve your pricing.
