My Student Loans Are Deferred — What Payment Do You Use?

The payment used in your debt-to-income (DTI) ratio depends entirely on which loan program you're going through. Fannie Mae uses the actual payment on your credit report, or the documented income-driven repayment (IDR) payment, or 1% of the balance — whichever is documented. Freddie Mac uses 0.5% of the balance. FHA uses the greater of 0.5% of the balance or the actual amortized payment. VA generally uses 5% of the balance divided by 12 unless a lower IDR payment is documented. Documenting an IDR payment — even $0 in some programs — is often the single highest-leverage move a borrower with student debt can make for DTI.

The handbook view (what the rules actually say)

Every major program has its own rule for how to count a deferred (or forbearance, or IDR) student loan in DTI. Here's what each handbook says:

• Fannie Mae (Conventional): Use the payment on the credit report. If the report shows $0 or no payment (deferred / forbearance), use the actual amortized payment from the loan's repayment terms, the documented IDR payment (including $0), or 1% of the outstanding balance — the documentation hierarchy accepts the lowest documented payment. (Source: Fannie Mae Selling Guide B3-6-05, Monthly Debt Obligations.)
• Freddie Mac (Conventional): If the credit report shows a payment, use it. If the loan is deferred or in forbearance and no payment shows, use 0.5% of the outstanding balance. (Source: Freddie Mac Single-Family Seller/Servicer Guide Section 5401.2, Stable Monthly Income and Asset Qualification Sources.)
• FHA: Use the greater of 0.5% of the outstanding balance or the actual documented monthly payment, regardless of deferment or forbearance status. An IDR payment shown on official documentation may be used if it is higher than 0.5% of the balance — but FHA will not use a $0 IDR payment; the 0.5% floor still applies. (Source: HUD Handbook 4000.1, II.A.5.a.iv, Installment Loans.)
• VA: If the loan is in deferment or the payment will not begin within 12 months of closing, the loan may sometimes be excluded with documentation. Otherwise, use the payment on the credit report; if it shows $0 or is missing, calculate 5% of the outstanding balance divided by 12. A documented lower IDR payment may be used instead. (Source: VA Pamphlet 26-7, Chapter 4, §4.07, Other Credit Considerations.)
• USDA Guaranteed Rural Housing: Aligns with the higher-of approach — fixed-payment loans use the credit-report payment; deferred or IDR loans use the greater of 0.5% of the balance or the actual documented payment. (Source: USDA Handbook HB-1-3555, Chapter 11.)

The plain-English translation

The DTI hit on a deferred student loan can vary by hundreds of dollars per month across programs. A $60,000 balance, depending on how the lender treats it:

• Fannie 1% of balance: $600/month charged to DTI — but if you have an IDR payment of $0 (or, say, $85) documented on a current statement, Fannie will use that lower number instead.
• Freddie 0.5% of balance: $300/month — the cleanest default rule. No IDR documentation needed.
• FHA greater of 0.5% or actual: $300/month floor; if the actual amortized payment is $450, FHA uses $450. FHA will not honor a $0 IDR — the 0.5% floor is the lowest you can get.
• VA 5% / 12: $250/month default — but with a documented IDR payment (including $0 in some cases), VA may use the lower number, and deferment past 12 months from closing can sometimes drop the debt out entirely.
• The lever is documentation. Pulling a current IDR-payment letter from your servicer before the loan officer runs DTI is the difference between $600 and $0 in the calculation on Fannie, and the difference between $250 and the actual lower IDR on VA.

Side-by-side: $60,000 deferred balance, by program

The table is a guideline, not a quote. The actual number used depends on what your credit report shows, what your servicer documents, and which program you're running. The right move is to pull a current IDR statement from your servicer before the lender runs AUS — that one document can move your DTI by several hundred dollars per month on a conventional file.

Lender overlays — where the rules get tighter

Two lenders can both legally offer the same program and treat the same student loan differently. Common overlays:

• IDR documentation refusal: Some retail lenders won't accept any IDR statement and use the program default (1% on Fannie, 0.5% on Freddie) regardless. Wholesale investors usually follow the handbook.
• No-$0 overlay on Fannie: A handful of lenders impose a non-zero floor (often $1 or $10 minimum) on a documented $0 IDR payment, even though Fannie allows $0. The handbook position is the program position; this is overlay-only.
• VA 12-month-deferment exclusion not used: VA allows excluding a deferred loan that won't begin payments within 12 months of closing; many retail shops never apply that rule. Brokers familiar with the VA handbook structure will.
• Repayment-plan letter requirements: Some lenders require the IDR statement to be dated within 30 days; others 60. A stale statement gets the file kicked back to the default percentage. Pull the statement late in the process, not at application.
• Parent PLUS treatment: Parent PLUS loans owed by a parent are not the student's debt under any program — but they sometimes appear on the student's credit report. The fix is documentation showing the parent is the named borrower, which not every lender will pursue.

Which lenders we actually use for this scenario

For deferred-student-loan files, the lender choice matters more than people realize. Two typologies I lean on:

First, the “guideline-strict, low-overlay” wholesale lender. These shops actually let the agency guideline play out. If Fannie says we can use the documented IDR payment of $0, they let us use $0. They don't bolt on an overlay that says “minimum 1% of balance regardless.” That's the lender you want on a Conventional file with a high student-loan balance.

Second, for FHA files, the “manual-comfortable” wholesale lender — because FHA's 0.5% floor is unavoidable, but compensating factors carry the file when the resulting DTI gets tight. A lender with experience manually walking an FHA file through TOTAL Scorecard with documented rent payment history and reserves can save a file that the AUS doesn't love.

What I avoid: any wholesale lender whose overlay sheet says “student loans calculated at 1% of balance regardless of documentation.” That's a hard pass; we'll find a different lender.

Real-world cases

Composite (illustrative) — borrower with $180,000 in deferred federal student loans, on SAVE with a documented $0 monthly payment. Retail LO had pre-qualified her using 1% of balance, $1,800/mo. That $1,800 pushed her DTI from 38% to 49% on a conventional purchase she'd been told she couldn't afford. We documented the SAVE plan through the servicer (an official statement showing $0 payment + the IDR enrollment letter), ran DU with $0 student loan payment per Fannie B3-6-05. Approve/Eligible. She closed on a house she'd been told for a year she couldn't qualify for.

Another composite — VA borrower, $90,000 deferred student loans, IDR not yet recertified, no documented payment available. We used 5% of balance / 12 per VA guideline ($375/mo for qualifying). DTI tight but residual income passed handily; funded.

FHA composite — first-time buyer with $40,000 in deferred federal loans. Retail used 1% of balance ($400). We dropped to FHA's actual 0.5% floor ($200), DTI dropped 4 points, she got the house. The retail LO was just defaulting to the most conservative number in the room without checking the program guideline.

How the big retail lenders typically handle this

Retail's default behavior on deferred student loans is “use whatever number requires the least documentation,” which almost always means 1% of balance. The LO doesn't have to chase down a servicer letter, doesn't have to verify the IDR plan, doesn't have to explain the documented-payment exception to processing. So they quote you a phantom payment that's three to six times higher than your real obligation, and your DTI gets crushed.

Directionally, the right move on any deferred student loan file is to pull the official servicer documentation (current statement showing the monthly amount due, even if it's $0, plus IDR enrollment confirmation) BEFORE the application gets submitted. With that paper in hand, every program except FHA can typically use the documented number, and FHA at least uses the lower 0.5% floor. The broker channel knows to ask for this documentation upfront; the retail channel often won't, because it costs them time on the front end and they get paid on volume.

If you have deferred student loans and an LO tells you “we just use 1% of the balance,” ask them to read you Fannie Mae Selling Guide B3-6-05 or Freddie Mac Guide 5401.2 on documented IDR payments. If they can't, get a second opinion.

A simple decision rule

Before any program decision, work through these in order:

1. 1Log into your servicer portal and pull a current IDR or repayment-plan statement. This is the single highest-leverage 15 minutes in the entire mortgage process for a borrower with student debt.
2. 2If your IDR payment is $0 or low, lean Conventional Fannie Mae — that's where the documented IDR replaces the 1%-of-balance default, and the gap is largest.
3. 3If FHA is in the mix, remember the 0.5%-of-balance floor — there's no $0 path on FHA regardless of IDR documentation.
4. 4If VA-eligible and the deferment goes beyond 12 months from closing, ask the lender about the exclusion path — not every retail shop applies that rule.
