What Is a Good Debt-to-Income Ratio? (And How to Calculate Yours)

Published May 11, 2026 · 5 min read

When you apply for a mortgage, personal loan, or car loan, lenders don't just look at your credit score. They also calculate your debt-to-income ratio (DTI) — and it can make or break your application. Understanding your DTI before you apply gives you a major advantage.

What Is Debt-to-Income Ratio?

Your DTI ratio is the percentage of your gross monthly income that goes toward debt payments. It's calculated with a simple formula:

DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100

For example, if your monthly debt payments total $1,500 and your gross income is $5,000, your DTI is 30%.

Monthly debt payments include: mortgage or rent, minimum credit card payments, auto loans, student loans, personal loans, and any other recurring debt obligations. They do not include utilities, groceries, insurance, or subscriptions.

What Do Lenders Consider a Good DTI?

Different lenders have different cutoffs, but here's the general framework most use:

DTI Range What Lenders Think
Below 36%Excellent — strong approval odds
36%–43%Acceptable — most loans still available
43%–50%Risky — harder to qualify, higher rates
Above 50%Very difficult to get approved

For conventional mortgages, the maximum DTI is typically 43–45%. FHA loans allow up to 57% in some cases, but you'll face higher costs.

Front-End vs. Back-End DTI

Mortgage lenders often calculate two versions of DTI. The front-end ratio (also called the housing ratio) includes only your proposed housing payment — principal, interest, taxes, and insurance. Most lenders want this below 28%. The back-end ratio includes all monthly debts. This is what people usually mean by "DTI," and the 36–43% target applies here.

How to Lower Your DTI

There are only two ways to improve your DTI: reduce your debt payments, or increase your income. In practice, here's how:

Calculate Your DTI Now

Add up every monthly debt payment you make, divide by your gross monthly income, and multiply by 100. If your DTI is above 43%, work on reducing it before you apply for major credit. If it's below 36%, you're in strong shape.
