Your debt-to-income ratio (DTI) is the percentage of your monthly income that goes toward debt payments. Lenders use it as a primary factor in loan approval — most conventional mortgages require a DTI below 43%. This calculator helps you understand where you stand before applying for credit.
The Debt-to-Income Ratio Calculator divides total monthly debt payments by gross monthly income to produce a percentage that lenders use to assess borrowing risk. The methodology uses a simple ratio calculation: DTI = (Monthly Debt Payments / Gross Monthly Income) x 100. This ratio is one of the most important factors lenders consider, alongside credit score, because it measures a borrower's ability to manage monthly debt obligations relative to their income. Lenders typically have maximum DTI requirements: conventional mortgages usually cap at 43-45%, while FHA loans may allow up to 50% with compensating factors. The calculator helps prospective borrowers understand where they stand before applying for major loans like mortgages, auto loans, or personal loans. It identifies whether someone is likely to qualify for new credit or needs to pay down debt first. A lower DTI indicates better financial health and more borrowing capacity.
Result: Debt-to-Income Ratio: 30%. This is considered favorable by most lenders.
