The debt-to-income (DTI) ratio is a critical measurement used in evaluating a borrower's ability to manage monthly payments and repay debts. It specifically assesses the relationship between a borrower's total monthly debt payments and their gross monthly income, providing lenders insight into the borrower's financial stability.

By focusing on how much of a borrower's income goes towards debt obligations, the DTI ratio helps lenders determine whether an applicant can afford additional debt, such as a mortgage. A lower DTI indicates a more favorable financial position, as it suggests that a smaller proportion of income is consumed by debt payments, allowing for greater financial flexibility.

Understanding this concept is essential for both borrowers and lenders, as it plays a significant role in underwriting decisions and loan approvals.
