Frequently Asked Questions
What is a good DTI ratio for a mortgage?
For most conventional mortgages, lenders prefer a front-end DTI (housing only) below 28% and a back-end DTI (total debt) below 36%. Some government-backed loans (FHA, VA) allow higher DTIs up to 43-50% with compensating factors.
What’s the difference between front-end and back-end DTI?
Front-end DTI: Only housing costs (mortgage/rent + taxes + insurance) ÷ income.
Back-end DTI: All monthly debt payments ÷ income (this calculator shows back-end DTI).
How can I lower my DTI ratio?
Increase income: Side hustle, overtime, negotiate raise
Reduce debt: Pay down credit cards, avoid new debt, consolidate loans
Refinance: Lower interest rates reduce monthly payments
Extend loan terms: Longer terms lower monthly payments (but increase total interest)
What DTI do I need for a car loan?
Most auto lenders prefer a back-end DTI below 45-50%. However, lower is always better for better interest rates. A DTI below 36% typically qualifies for the best rates.
Does DTI include utilities and insurance?
Standard DTI calculations do not include utilities, cell phone bills, cable, or health insurance. This calculator focuses on debt payments reported to credit bureaus (loans, credit cards, mortgage) plus rent.
Why does the calculator show “Excellent (0-20%)”?
A DTI below 20% means you have significant income left after paying debts. Lenders view this as very low risk. You may qualify for the best interest rates and loan terms.
