Your credit score gets all the attention, but there's another number lenders care about just as much: your debt-to-income ratio (DTI). It tells lenders how much of your monthly income is already committed to debt payments. A high DTI can get you denied for a loan even if your credit score is excellent.
What DTI Is and How to Calculate It
Your debt-to-income ratio is simple math. Add up all your monthly debt payments (credit cards, car loans, student loans, mortgage, minimum payments on everything), then divide that by your gross monthly income (before taxes). Multiply by 100 to get a percentage.
For example, if you pay $500 on a car loan, $200 in credit card minimums, and $300 on student loans, your total monthly debt is $1,000. If your gross monthly income is $4,000, your DTI is 25% ($1,000 / $4,000 = 0.25).
Lenders look at two types of DTI. The "front-end" ratio only includes housing costs (mortgage or rent). The "back-end" ratio includes all debts. When people say DTI, they usually mean back-end.
Understanding how credit scores are calculated alongside your DTI gives you a complete picture of how lenders evaluate you.
Ideal DTI Ratios for Different Loan Types
Mortgages are the most DTI-sensitive. Most conventional lenders want a back-end DTI of 43% or lower. FHA loans may allow up to 50% with compensating factors. The lower your DTI, the better your chances and the better your rate. If your credit profile also needs work before you apply, our guide on how to get pre-approved for a mortgage with bad credit covers what underwriters weigh alongside DTI.
Auto loans are more flexible. Many lenders will approve borrowers with DTIs up to 50%, though you'll get better terms under 40%.
Personal loans vary widely by lender. Online lenders tend to be more lenient than traditional banks. A DTI under 35% gives you the most options.
Credit cards don't have strict DTI requirements, but issuers still consider your income relative to your existing debt when setting credit limits.
The sweet spot for most lending situations is a DTI under 36%. At this level, you have plenty of options and will generally qualify for competitive rates.
If a temporary cash gap is pushing you toward another high-interest loan that would raise your DTI, a low-cost advance can bridge the shortfall instead. MoneyLion fits here because its Instacash advances carry no mandatory interest, so you can cover an expense without adding a new monthly payment that inflates your ratio.

How to Lower Your DTI
Pay down existing debt. The most direct approach. Focus on eliminating your highest monthly payments first. Even paying off a small credit card balance removes that minimum payment from your DTI calculation.
Increase your income. The other side of the equation. A raise, side job, or freelance work increases your denominator and lowers your ratio. Lenders typically want to see consistent income for at least two years, so start early.
Avoid taking on new debt. Every new loan or credit card with a balance adds to your monthly obligations. If you're planning a major purchase like a home, avoid financing anything else in the months leading up to your application.
Refinance to lower payments. If you can refinance a car loan or student loan to a lower monthly payment (even if it extends the term), your DTI improves. Be careful though—extending loan terms means paying more interest overall.
Don't confuse DTI with credit utilization. Credit utilization (how much of your credit limit you're using) affects your credit score. DTI is a separate calculation that doesn't appear on your credit report at all—lenders calculate it from your application. Both matter, but they measure different things. Learn more about improving your credit before a big purchase to prepare on both fronts.

Your debt-to-income ratio is one of the most overlooked factors in loan approval. You can have a perfect credit score and still get denied if your DTI is too high. The good news: unlike credit scores that take months to improve, you can lower your DTI quickly by paying off debt or increasing income. Keep your DTI under 36%, build strong credit with Firstcard, and you'll be in the best position when it's time to borrow.
Avoiding overdraft fees and last-minute borrowing also protects your ratio, since each new obligation nudges your DTI higher. Brigit is a good fit because it combines budgeting tools with interest-free advances, helping you smooth out cash-flow dips without taking on a payment that lenders would count against you.

FAQ
Does DTI affect my credit score? No. DTI doesn't appear on your credit report and doesn't factor into your credit score. However, lenders evaluate both your score and your DTI when making lending decisions.
What's considered a high DTI? A DTI above 43% is generally considered high and will limit your borrowing options, especially for mortgages. Above 50%, most lenders will decline your application.
Does rent count in DTI calculations? If you're applying for a mortgage, your current rent is replaced by the projected mortgage payment in the DTI calculation. For other loans, rent typically isn't included unless it shows on your credit report.
Can I get a mortgage with a DTI above 43%? Some loan programs (like FHA) allow higher DTIs with compensating factors such as significant savings, a large down payment, or excellent credit. But your options narrow significantly above 43%.
How quickly can I lower my DTI? As fast as you can pay off debt or increase income. Paying off a credit card balance lowers your DTI immediately on your next application. Income increases need to be documented (usually via pay stubs or tax returns).
