Why Your Debt-to-Income (DTI) Ratio Matters
Before a lender approves you for a mortgage or auto loan, they want to know one thing: Can you afford the monthly payments? Your Debt-to-Income (DTI) ratio gives them the answer. It is one of the most important numbers in your financial life, right next to your credit score.

How to Calculate Your DTI
The math is simple. Divide your total monthly debt payments by your gross monthly income (income before taxes).
(Total Monthly Debt / Gross Monthly Income) x 100 = DTI %
Included Debts: Rent/Mortgage, Car Loans, Student Loans, Credit Card Minimums, Child Support.
Excluded Expenses: Groceries, Utilities, Gas, Entertainment (these are living expenses, not debts).
What is a Good DTI Ratio?
Lenders categorize borrowers based on risk:
- 35% or less: Excellent. You look financially stable and are likely to get the best rates.
- 36% to 43%: Good. You can still qualify for most mortgages, but you are carrying significant debt.
- 44% to 49%: High Risk. You may only qualify for FHA loans or specialized lenders.
- 50% or more: Critical. Most lenders will deny a new loan request until you pay down debt.
Strategies to Lower Your DTI
- The "Snowball" Method: Focus on paying off the smallest debt balance (e.g., a $500 credit card) first. Eliminating that monthly payment instantly improves your DTI.
- Refinance Loans: Refinancing a car loan to a lower rate or longer term can reduce the monthly payment, improving your ratio.
- Increase Income: Picking up a side gig or overtime shifts increases the "Income" side of the equation.
