DTI = (TotalMonthlyDebt / GrossMonthlyIncome) × 100

FAQ

Frequently asked questions

What counts as debt in this calculation?

Minimum payments on credit cards, auto loans, student loans, personal loans, and housing costs — not everyday expenses like groceries or utilities.

What's considered a good DTI?

Below 36% is generally seen as healthy, 37–43% is borderline for many lenders, and above 43% can make qualifying for a mortgage harder.

How can I lower my DTI?

Pay down revolving balances, avoid new debt before a big application, or increase verifiable income.
