Debt to Income (DTI) Calculator
Estimate the share of gross monthly income used for housing and recurring debt payments. The calculator uses monthly gross income, housing payment, car loan, student loan, credit card payment, and other debt payments to show DTI ratio and a basic risk label.
How to use this calculator
Enter monthly gross income before taxes and required monthly debt payments. Include housing, car loans, student loans, minimum credit card payments, and other recurring debts. The result is housing-inclusive DTI. To test new borrowing, compare payments from the auto loan calculator, personal loan calculator, or mortgage calculator.
Formula
DTI is calculated as:
This form includes housing in total debt. Some lenders also look separately at front-end housing ratio and back-end total debt ratio.
Example
If gross monthly income is 5,000 dollars and payments are 1,500 dollars for housing, 300 dollars for a car loan, 200 dollars for student loans, and 100 dollars for credit cards, total monthly debt is 2,100 dollars. DTI is 42 percent.
Interpreting DTI
Lower DTI generally means more income is uncommitted, but lender rules vary by loan type, credit profile, assets, and documentation. Everyday costs such as groceries and utilities are not part of this formula, so also review a complete budget calculator.
