Add your total monthly debt payments (minimum required payments for credit cards, loans, car payments, student loans, personal loans, etc.)
Include housing-related payments if applicable (monthly mortgage/rent plus required property taxes and insurance, if your lender includes them)
Divide total monthly debt payments by your gross monthly income (income before taxes)
Multiply the result by 100 to convert it to a percentage
Use the formula: DTI (%) = (Total monthly debt payments / Gross monthly income) × 100
Example inputs: $1,500 total monthly debt payments and $5,000 gross monthly income
Example calculation: (1,500 / 5,000) × 100 = 30% DTI
