Debt-to-Income Ratio

Also known as DTI

The share of your monthly gross income that goes toward debt payments, used to judge affordability.

In plain English

DTI compares your total monthly debt payments (including your future mortgage) to your gross monthly income. Lenders generally want your DTI under 43%–50% to approve a mortgage, though the exact limit varies by loan program.

Why it matters

Your DTI is one of the biggest factors in how much you can actually borrow — paying down other debt before applying can meaningfully increase what you qualify for.
