“Lenders typically prefer a DTI ratio below 36%.”

Your Debt-to-Income (DTI) ratio is one of the most critical figures lenders use to evaluate your financial health and borrowing capacity. The Debt-to-Income (DTI) Calculator is a professional-grade utility designed to help you see your finances through the eyes of a bank. By comparing your total monthly debt obligations—including housing costs, car payments, student loans, and credit card minimums—against your gross monthly income, this tool calculates your DTI percentage with precision. Understanding this ratio is essential for anyone planning to apply for a mortgage, as most lenders look for a DTI of 43% or lower to qualify for a Qualified Mortgage.
