What Is Debt-to-Income Ratio?

Your DTI ratio is the percentage of your gross monthly income that goes toward debt payments. Banks and lenders use it to gauge whether you can take on more debt without getting into trouble.

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

There are two versions:

DTI Ranges and What They Mean

How to Lower Your DTI

Two levers: reduce debt payments or increase income. Some specific moves:

  1. Pay off a car loan or credit card. Eliminating even one monthly payment can drop your DTI several points.
  2. Refinance for lower payments. Extending a loan term lowers the monthly payment (though you pay more interest overall).
  3. Avoid new debt in the 6–12 months before applying for a mortgage.
  4. Add income. A raise, side gig, or documented rental income counts toward gross income.

DTI Requirements by Loan Type

Conventional (Fannie Mae)28%36–45%

These are guidelines, not absolutes. Compensating factors — high credit score, large down payment, significant cash reserves — can push the limit higher.

How to Lower Your DTI Ratio

If your DTI is too high for the loan you want, there are two strategies: increase income or reduce debt. Here are specific tactics:

DTI vs. Credit Score: Which Matters More?

Lenders look at both, but they measure different things. Your credit score shows how reliably you pay. Your DTI shows how much capacity you have to pay. A perfect 850 credit score won’t help if your DTI is 60% — you simply don’t have enough income to take on more debt safely.

The ideal mortgage applicant has both: a credit score above 740 and a DTI below 36%. If your DTI is borderline, a high credit score can be a compensating factor. But if your DTI exceeds 50%, even excellent credit usually can’t overcome it.

Frequently Asked Questions

How to Use This Debt-to-Income Ratio Calculator

Enter your monthly gross income and all monthly debt payments (mortgage, car loan, student loans, credit cards, other). The calculator shows your DTI ratio.

Formula & How It Works

DTI = Total Monthly Debt Payments / Gross Monthly Income Γ— 100%. Front-end DTI: housing costs only. Back-end DTI: all debts combined.

Calculation Example

Gross income $6,500/mo. Debts: mortgage $1,500, car $400, student loan $300, credit cards $200. DTI = $2,400/$6,500 = 36.9%.

Expert Tips

Lenders prefer DTI below 36% (back-end). FHA allows up to 43%. For the best mortgage rates, aim for under 28% front-end and 36% back-end. Pay off small debts before applying to lower your DTI quickly.

What is a good debt-to-income ratio?

Below 36% is considered good by most lenders. Below 28% for housing costs alone (front-end ratio). Above 43% makes it hard to qualify for a conventional mortgage.

What debts count toward DTI?

Monthly minimum payments on credit cards, auto loans, student loans, personal loans, mortgage or rent, child support, and alimony. Utilities, groceries, insurance premiums, and subscriptions do not count.

How do I lower my DTI ratio?

Pay down existing debts (especially high-balance credit cards), avoid new loans, increase your income, or refinance for lower monthly payments. Paying off a car loan can move the needle fast.

Does rent count as debt for DTI?

When you apply for a mortgage, your current rent is replaced by the estimated mortgage payment in the DTI calculation. For other loan types, it depends on the lender.

What DTI do I need for a mortgage?

Conventional loans: below 43–45%. FHA loans: up to 50% with strong compensating factors. VA loans: no strict limit, but lenders prefer below 41%.
