Starting July 1, 2026, the One Big Beautiful Bill Act requires federal student loans to be prorated for students enrolled less than full-time. Your annual loan amount is now multiplied by the fraction of a full-time schedule you're carrying. A half-time undergrad gets 50% of the standard limit. Below 6 credits per semester, you get nothing. The change applies to all borrowers starting with the 2026-27 academic year — no exceptions for students who previously had loans.
Most students assume their federal loan package is fixed — fill out the FAFSA, get approved for an amount, and borrow it. Until recently, that was essentially true for enrollment: as long as you were enrolled at least half-time, you could access the full annual loan limit for your grade level.
That changed on July 1, 2026.
Under a provision of the One Big Beautiful Bill Act (OBBBA), all federal student loan disbursements for students enrolled less than full-time are now prorated in direct proportion to your enrollment percentage. The change took effect with loans for the 2026-27 academic year and applies to all borrowers — there is no grandfather clause for students who already had loans before July 1.
How the Math Works
The formula is simple, but the results are significant.
Annual loan eligibility = Annual limit × (credits enrolled ÷ full-time credit load)
Full-time is defined as 12 or more credits per semester for undergrads (24 credits per academic year) and 9 or more credits per semester for graduate students (18 credits per academic year).1
Here's what that looks like for an undergraduate junior or senior, whose standard annual unsubsidized loan limit is $12,500:
| Credits per semester | % of full-time | Annual loan eligibility |
|---|---|---|
| 12 (full-time) | 100% | $12,500 |
| 9 | 75% | $9,375 |
| 6 (half-time) | 50% | $6,250 |
| 5 or fewer | Below half-time | $0 |
For graduate students, Johns Hopkins University's financial aid office gives a concrete example: a student expected to take 9 credits per semester (18 credits per year for full-time) who enrolls in 9 credits in the fall receives 50% of the $20,500 annual limit — or $10,250 — for that semester.1
The reduction isn't applied automatically to your FAFSA; financial aid offices apply it at disbursement based on actual enrollment at the time your loans are processed.
Proration happens at disbursement, not when you file the FAFSA. If you enroll full-time in the fall, receive your full loan disbursement, and then drop credits below full-time thresholds mid-semester, your school may adjust your loan — or require repayment of a portion. Check your school's enrollment certification policy before making any schedule changes after your loans have already been paid out.
Who This Hits Hardest
Working students and caregivers. Students who work significant hours — or who care for children or aging parents — have long relied on part-time enrollment as their only realistic option. Proration doesn't change the cost of their degree; it just reduces help paying for it. Room, food, and transportation don't shrink because you're taking 9 credits instead of 15.
Students in professionally structured programs. Some certificate and professional programs are designed around nine or ten credits per semester by default. Students in those tracks may automatically lose a portion of their federal loan eligibility without realizing the new rules apply to them.
Adult learners returning to school. The financial aid picture for students returning as adults was already complicated. Proration adds another variable to manage. If you're going back to school part-time while employed, get your prorated number in writing from the financial aid office before you build your budget.
Graduate students. With Grad PLUS loans eliminated for new borrowers as of July 1, graduate students are already dealing with tighter borrowing ceilings. Proration on top of that further narrows options for anyone in a program structured around less than full-time credits.2
If you're considering dropping from full-time to part-time to ease your workload, run the loan numbers before you finalize the change. Dropping from 12 to 9 credits per semester costs you 25% of your annual loan eligibility. Most schools lock in your enrollment status for financial aid after the add/drop deadline, so there's usually no way to undo it mid-semester.
What to Do If Your Loans Got Cut
Call your financial aid office before finalizing your schedule. Ask them to show you the prorated amount you'd receive at each enrollment level you're considering. The gap between 9 and 12 credits per semester can mean thousands of dollars in lost borrowing power.
Stack grants and scholarships. Private scholarships and institutional grants are not subject to proration. They're available regardless of how many credits you take and don't add to your loan balance.
Ask about employer tuition benefits. Many employers offer tuition reimbursement programs. If you're working while studying, this is often the most underutilized option available to you.
Consider a tuition payment plan. Many schools offer monthly installment plans that spread tuition over 4–6 months at no interest. If your loan gap is small, this can cover it without additional borrowing.
Think about total debt. If your prorated loan amount covers your actual costs, graduating with a smaller loan balance is a real benefit. The new Repayment Assistance Plan (RAP) caps monthly payments as a percentage of income, but less total debt means more flexibility regardless of which repayment plan you use.
