Yes. Student loans do count toward your debt-to-income ratio, and they count with every type of lender, from mortgage underwriters to auto finance offices to credit card issuers. The monthly payment on your student debt gets added to your other obligations and measured against your gross monthly income. What makes student loans different from most other debts is that the “monthly payment” a lender uses is not always the number on your credit report. If you’re in deferment, forbearance, or an income-driven plan showing $0 due, most mortgage programs plug in a calculated figure instead.
Your DTI is total monthly debt payments divided by gross monthly income, expressed as a percentage.1Legal Information Institute. Debt-to-Income Ratio Lenders care most about the back-end version, which bundles housing costs together with car loans, credit cards, personal loans, and student loans. That’s the number your student debt feeds into.
When You’re Actively Paying
If you’re making regular payments on a standard plan, this part is simple. The lender pulls the fixed monthly amount from your credit report and drops it straight into the calculation. The federal standard plan amortizes your balance over 10 years with a minimum payment of $50.2Federal Student Aid. Standard Repayment Plan Private loans work the same way: your promissory note sets a specific monthly payment, your servicer reports it, and the lender uses it.
One complication: if your payment is not fully amortizing, meaning it won’t actually zero out the balance by the end of the term, mortgage programs will not trust the reported figure. Interest-only payments and graduated payments that start artificially low fall into this category. Fannie Mae substitutes 1 percent of the outstanding balance in that situation. FHA uses the greater of the actual reported payment or 0.5 percent of the balance.3U.S. Department of Housing and Urban Development. Mortgagee Letter 2016-08 – Student Loans
When Your Credit Report Shows $0
A $0 payment on your credit report does not erase the debt from your DTI. The legal obligation still exists, and lenders fill the gap with an estimated payment. The exact method depends on which mortgage program you’re applying under, and the differences are large enough to decide approvals.
Fannie Mae (Conventional)
Fannie Mae requires lenders to use 1 percent of the outstanding balance as the monthly payment any time the borrower cannot document a fully amortizing payment. This includes deferment, forbearance, and income-driven plans with a $0 calculated payment.4Fannie Mae. B3-6-05 Monthly Debt Obligations On a $50,000 balance, that’s $500 added to your monthly debt load whether you’re actually paying anything or not.
Freddie Mac (Conventional)
Freddie Mac is friendlier on this point. For deferred loans, Freddie uses 0.5 percent of the outstanding balance.5Freddie Mac. Guide Section 5401.2 On that same $50,000 balance, you’d see $250 instead of $500. If you’re pursuing a conventional loan with heavy student debt, which agency your lender sells to can matter.
FHA
FHA uses 0.5 percent of the outstanding balance when the credit report shows a zero payment, regardless of whether that zero comes from deferment or an IDR calculation.6U.S. Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook 4000.1 FHA previously used a 1 percent rule, so this change made qualifying significantly easier for borrowers with large balances.
USDA
USDA Rural Development loans follow the same 0.5 percent approach as FHA for zero-payment student loans.7USDA Rural Development. Ratio Analysis Training
VA
VA is the outlier, and in the borrower’s favor. If your student loans are deferred for at least 12 months beyond the closing date of your VA mortgage, the lender does not count the payment at all.8VA Credit Standards Course. VA Credit Standards Course For DTI purposes, the balance effectively disappears during that deferment window. If deferment ends within 12 months of closing, the anticipated payment goes back into the analysis.
VA also treats a documented $0 IDR payment at face value: zero added to your DTI, provided you deliver a servicer statement confirming the current required payment and the plan you’re enrolled in. Without that documentation, VA lenders fall back to 5 percent of the outstanding balance divided by 12.
Income-Driven Plans With a Payment Above Zero
Federal IDR plans like Income-Based Repayment and Pay As You Earn set monthly payments based on discretionary income and family size, which can push the required payment down to $0 for lower earners.9Federal Register. Improving Income Driven Repayment for the William D. Ford Federal Direct Loan Program and the Federal Family Education Loan (FFEL) Program When your IDR payment is above zero, most lenders simply use the reported amount from your credit file or a current billing statement.
Expect scrutiny. Underwriters examine IDR payments more carefully than standard ones, and documentation stops delays. Have a servicer letter or Student Loan Certification ready that shows your exact payment, plan type, and remaining balance. That paperwork at application time can save weeks of back-and-forth later.
Cosigned Loans Still Count
A student loan you cosigned for a child or anyone else sits on your credit report and lands in your DTI, even if someone else makes every payment on time. This catches many parents off guard when they apply for a mortgage years after signing.
Some mortgage programs let you exclude a cosigned loan from your DTI if you can document that the primary borrower has made the payments consistently, typically for 12 consecutive months, with no lates. You’ll need canceled checks or bank statements from the primary borrower showing the payments came from their own account. Freddie Mac may also exclude the payment when 10 or fewer payments remain.
The cleaner fix is getting released as a cosigner. Many private lenders offer cosigner release after the primary borrower has made a set number of on-time payments and can show enough income and credit to carry the loan alone. Federal Parent PLUS loans don’t offer release, but the student can consolidate the debt into a Direct Consolidation Loan in their own name, which removes the parent from the obligation.
How to Shrink the DTI Hit
If your student loans are pushing your DTI past the ceiling, you have options short of paying the balances off.
Enroll in an IDR plan before applying, but check who accepts the documented payment. A borrower with $80,000 in federal loans and a $200 IDR payment saves $600 per month on the DTI calculation versus Fannie Mae’s 1 percent rule. The catch: Fannie Mae still uses 1 percent even when IDR shows a payment, so this strategy pays off only with programs that honor the documented figure.
Refinance into a longer term. Stretching a 10-year repayment to 20 years cuts the monthly payment substantially. You pay more interest over the life of the loan, but DTI only sees the monthly number. The payment has to be fully amortizing for most programs to accept it.
Choose the mortgage program that treats your loans best. This is where most borrowers leave money on the table. A VA borrower whose student loans are deferred past the 12-month window counts them as $0. The same borrower under Fannie Mae would see 1 percent of the balance added. If you’re choosing between FHA and conventional, FHA’s 0.5 percent is a lighter hit than Fannie Mae’s 1 percent on the same balance. Run your numbers through each program’s formula before you commit to one.
Clear small debts first. A $350 car payment with four months left disappears from your DTI entirely once it’s paid off, freeing up the same room as roughly $35,000 in student loans would under Fannie Mae’s 1 percent rule.
