Student debt DTI impact

Debt-to-income is total monthly debt payments divided by gross monthly income. Enter your student loan payment, other debts, and housing payment (or an estimate). Toggle student loan exclusion to model a physician-program assumption — then verify with a lender.

Formula: DTI = (student loans + other debts + housing) ÷ gross monthly income

Keep your actual payment above. Enter the monthly student-loan amount your lender says will count. This is your scenario assumption; the tool does not verify the lender’s treatment or approval.

Front-end vs back-end DTI

This tool shows a single combined ratio (housing plus debts divided by income). Some lenders also track housing-only DTI. Ask which ratio drives your file if you are near a limit.

Adding a co-borrower

Re-run the tool with combined income and combined debts if two borrowers will be on the note. Student loans on only one credit report may still count depending on lender policy.

About this tool

What DTI do lenders use?
Guidelines vary by program and lender. This tool shows the math from your inputs — not a maximum allowed ratio.
Can physician programs exclude student loans?
Some may, for some borrowers. Toggle the exclusion checkbox to model that assumption, then confirm with a loan officer.
How do I compare a lender-counted student-loan payment?
Keep your actual monthly payment in the student-loan field, then enter the lender-counted amount in the optional field. The comparison shows both DTI calculations. Leaving the optional field blank keeps that amount unknown; entering zero models a counted payment of zero.
