Debt-to-income ratio formula
DTI is monthly debt payments ÷ gross monthly income × 100%. It summarizes how much of gross income is committed to recurring debt payments.
What counts as monthly debt
Common lending calculations can include housing payments, minimum credit-card payments, auto loans, student loans and other recurring debts. Definitions differ by lender and loan program.
DTI is only one lending factor
A lower ratio generally means more income remains after debt payments, but approval also depends on credit history, assets, down payment, loan type and lender rules.
