Debt-to-Income Ratio: What It Is and Why Lenders Care
Your DTI ratio determines if you qualify for a mortgage, car loan, or credit card. Learn how to calculate yours and lower it fast.
What Is Debt-to-Income Ratio?
Your debt-to-income ratio (DTI) is the percentage of your monthly gross income that goes toward debt payments. It tells lenders how much room you have to take on new debt.
DTI = Monthly Debt Payments / Monthly Gross Income × 100
How to Calculate Yours
Monthly debt payments include:
- Mortgage or rent
- Car payments
- Student loans
- Credit card minimums
- Personal loans
- Child support/alimony
Monthly debt does NOT include:
- Utilities, groceries, insurance
- Phone, internet, subscriptions
- Taxes (unless owed to IRS with payment plan)
Example
- Monthly income: $6,000
- Mortgage: $1,500
- Car payment: $400
- Student loan: $300
- Credit card minimums: $200
- DTI = $2,400 / $6,000 = 40%
What Lenders Want
| DTI Range | Rating | Loan Eligibility | |-----------|--------|-----------------| | Under 20% | Excellent | Best rates, all loan types | | 20-35% | Good | Most loans approved | | 36-43% | Acceptable | May qualify with strong credit | | 43-50% | High | Limited options, FHA possible | | Over 50% | Too high | Most lenders will decline |
By Loan Type
- Conventional mortgage: Max 43-45% DTI
- FHA mortgage: Max 50% DTI (with compensating factors)
- VA loan: No official DTI limit, but 41% is the benchmark
How to Lower Your DTI
Quick methods:
- Pay off smallest debts first — Eliminating a $200/month payment drops your DTI immediately
- Increase income — Side gig income counts if documented
- Refinance at lower payments — Extending loan terms lowers monthly obligations
Medium-term:
- Avoid new debt — Don't finance anything before applying for a mortgage
- Pay down credit card balances — Lower balances = lower minimums
- Consolidate high-interest debt — One lower payment instead of many
DTI vs. Credit Score
Your DTI and credit score are different things:
- Credit score: Based on payment history, utilization, account age
- DTI: Based on income vs. debt payments
You can have an 800 credit score and still be denied a mortgage if your DTI is too high. Lenders look at both.
