Debt-to-Income Calculator

Your debt-to-income ratio is the percentage of your gross monthly income that goes toward paying debts. Lenders use DTI as a key measure of your ability to manage monthly payments and repay borrowed money. A DTI below 36% is generally considered favorable, while a ratio above 43% may make it difficult to qualify for most conventional mortgage loans. This single metric plays a major role in loan approval decisions across all types of consumer lending.

Front-end DTI measures only your housing-related expenses, including mortgage payment, property taxes, homeowners insurance, and HOA fees, divided by your gross monthly income. Back-end DTI includes all monthly debt obligations such as housing costs plus credit cards, auto loans, student loans, and any other recurring debt payments. Most mortgage lenders prefer a front-end DTI below 28% and a back-end DTI below 36%, though some loan programs allow ratios up to 50%.

Mortgage lenders typically require a back-end DTI of 43% or less for qualified mortgages under federal lending guidelines. FHA loans may allow DTI ratios up to 50% with strong compensating factors like a high credit score or significant cash reserves. For personal loans and auto loans, lenders have their own DTI thresholds but generally prefer borrowers with ratios below 40%. A lower DTI signals to lenders that you have sufficient income to comfortably handle additional debt payments.

The fastest way to lower your DTI is to pay down existing debts, starting with the accounts that have the highest monthly minimum payments. Increasing your gross income through a raise, side job, or additional income sources also improves the ratio. Avoid taking on new debt before applying for a major loan, and consider paying off small account balances entirely to eliminate their minimum payments from your DTI calculation.
