Frequently Asked Questions
The Debt-to-Income (DTI) ratio is a personal finance metric that measures the percentage of your gross monthly income (before taxes) that goes toward paying recurring monthly debts (such as rent, mortgage, car payments, student loans, and credit card minimums).
Front-End DTI (or the housing ratio) only includes housing-related expenses like your monthly mortgage principal, interest, property taxes, homeowners insurance, and HOA dues. Back-End DTI includes housing costs plus all other monthly recurring debt payments (credit cards, auto loans, student loans, child support, etc.). Lenders prioritize the Back-End DTI.
Generally, lenders prefer a back-end DTI of 36% or less for conventional mortgages, with no more than 28% allocated to housing expenses (front-end). However, many loan programs (like FHA or VA) allow back-end DTI ratios up to 43%, and in some cases up to 50% with strong compensating factors (high credit score, cash reserves).
No, your debt-to-income ratio is not calculated by credit bureaus and does not affect your FICO credit score directly. However, the amounts you owe on revolving credit lines do affect your credit utilization ratio, which is a major factor in determining your credit score.
You can lower your DTI by either increasing your gross monthly income (e.g. through side hustles, raises, or roommate rent contributions) or by reducing your monthly debt obligations. Paying off credit card balances entirely, refinancing high-interest loans, or avoiding new financing are the most effective ways to lower monthly payments.
