Debt-to-Income Calculator

This debt-to-income calculator helps you understand how much of your gross monthly income is already committed to housing and recurring debt payments.

This page is aimed at borrowers who need quick underwriting-style context before applying for a mortgage, auto loan, or other financing. Showing both front-end and back-end ratios makes it more practical than a single DTI number alone.

Enter gross monthly income and your recurring debt obligations to calculate front-end and back-end DTI ratios. The calculator also shows rough housing-payment guidance based on common 28/36 rule benchmarks.

Common questions

What is debt-to-income ratio?

Debt-to-income ratio compares recurring monthly debt payments with gross monthly income to show how leveraged your budget already is.

What is the difference between front-end and back-end DTI?

Front-end DTI looks only at housing costs, while back-end DTI includes housing plus other recurring debts such as car, student, and credit card payments.

What DTI is considered good?

Many lenders prefer lower ratios, and common benchmark rules often reference 28% for housing and 36% for total recurring debt, though real approvals vary.
