Which statement correctly defines debt-to-income ratio (DTI) and its impact on loan decisions?

• A. DTI = gross monthly income / total debt payments; higher DTI signals lower risk.
• B. DTI = total debt payments divided by gross monthly income; higher DTI signals higher risk and can limit loan approval or increase rates.
• C. DTI = total debt payments minus gross monthly income; higher DTI signals greater savings.
• D. DTI = gross monthly income minus debt payments; higher DTI signals stronger credit.

Answer: (B)

Understanding how debt-to-income (DTI) works helps explain why this ratio matters for loans. DTI measures how much of your gross monthly income is committed to debt payments each month. It’s calculated by dividing total monthly debt obligations by gross monthly income. A higher DTI means a larger share of income goes to debt, leaving less available to cover a new loan payment, which lenders view as a higher default risk. Because of that, a high DTI can limit loan approval or lead to higher interest rates, depending on the loan program. For example, if gross monthly income is $6,000 and total debt payments are $2,400, the DTI is 40%, a common threshold lenders consider; higher DTIs may trigger requirements like a larger down payment or a cosigner. The other ways of framing the ratio are not correct because they either invert the relationship (income divided by debt payments), yield meaningless or misleading results, or describe discretionary income rather than the risk-focused measure lenders use.
