How debt-to-income ratio is calculated
Add recurring monthly debt payments and divide the total by gross monthly income before taxes. Optional debt fields can remain blank when they do not apply.
Standard DTI calculations generally exclude taxes, utilities, groceries, insurance, and other living expenses unless a lender defines its calculation differently. This result is a mathematical estimate, not lending or financial advice.
Worked example
With $5,000 in gross monthly income, a $1,500 housing payment, a $350 auto payment, a $200 student loan payment, and $50 in credit card minimums, total debt is $2,100. The calculation is $2,100 ÷ $5,000 × 100 = 42%.
What to include
- Monthly rent or mortgage payment used by the lender
- Required auto and student loan payments
- Credit card minimum payments rather than the full card balance
- Other recurring obligations a lender treats as debt
Frequently asked questions
Can a debt-to-income ratio be higher than 100%?
Yes. A result above 100% means the entered monthly debt payments exceed gross monthly income. The calculator displays that mathematical result without capping it.
Do lenders all calculate DTI the same way?
No. Lenders may use different income documentation, housing-payment definitions, debt exclusions, or qualification rules. Confirm the applicable method with the lender.
Are utilities, groceries, and taxes included in DTI?
They are generally excluded from standard DTI calculations because they are living expenses rather than recurring debt payments, though a lender may define its calculation differently.
