Frequently Asked Questions
What is debt-to-income ratio (DTI)?
Your debt-to-income ratio is the percentage of your gross monthly income that goes toward debt payments. Lenders use it to evaluate your ability to manage monthly payments and repay loans.
How is DTI calculated?
DTI = (Total Monthly Debt Payments ÷ Total Monthly Income) × 100. A lower DTI indicates better financial health and higher borrowing capacity.
What is a good DTI ratio?
A DTI of 36% or less is considered good. 37-43% is acceptable but may limit borrowing options. Above 43% may make it difficult to get approved for loans.
What is the difference between front-end and back-end DTI?
Front-end DTI only includes housing expenses (mortgage/rent, property taxes, insurance). Back-end DTI includes all debts (housing, auto, credit cards, student loans, etc.).
What is the maximum DTI for a mortgage?
Most conventional mortgages require a back-end DTI of 43% or less. FHA loans may allow up to 50% with compensating factors.
