When a Title IV recipient withdraws before completing a payment period, federal aid does not simply stay where it landed. The Return of Title IV Funds (R2T4) calculation determines how much aid the student earned as of withdrawal and how much the school and student must return. For clock-hour programs the calculation has its own arithmetic — built on scheduled hours, not completed hours — and it is one of the most error-prone processes in trade-school financial aid.

The core formula: scheduled hours, not completed hours

For a clock-hour program, the percentage of aid earned is:

Clock hours the student was scheduled to complete in the payment period as of the withdrawal date ÷ total clock hours in the payment period

This is the single most misunderstood point in clock-hour R2T4. A student scheduled for 300 of the payment period's 450 hours as of the withdrawal date has an earned percentage of 66.7 percent — even if the student actually attended only 220 of those hours. Attendance determines the withdrawal date; the schedule determines the percentage. Schools that divide completed hours by total hours are running the calculation wrong, and every withdrawal they process compounds the error.

"Scheduled" means the hours the student was scheduled to attend under the program's published schedule for that student, from the start of the payment period through the withdrawal date. This is why an accurate, student-specific schedule is an R2T4 compliance document, not just an operations artifact.

The 60% point

If the student's scheduled-hours percentage exceeds 60 percent of the payment period, the student has earned 100 percent of the Title IV aid for that period, and no return calculation reduces it (you still complete the R2T4 worksheet to document that fact, and a post-withdrawal disbursement may still be due).

At or below the 60% point, aid is earned pro rata. The unearned portion is allocated between the school and the student under the FSA Handbook's return hierarchy, with the school's share driven by institutional charges for the period.

Determining the withdrawal date

Most clock-hour schools are required to take attendance — by their accreditor, their state, or their own policy — and for an institution required to take attendance, the withdrawal date is the last date of academic attendance as shown in the attendance records. There is little judgment involved; there is also nowhere to hide if attendance records are incomplete.

Two related dates matter and are routinely confused:

For a student who stops attending without notice, the school must identify the withdrawal within the timeframe in the FSA Handbook — for attendance-taking institutions, a school is expected to determine the withdrawal no later than 14 days after the last date of attendance. A student on an approved leave of absence who fails to return is treated as withdrawn, with dates determined under the LOA rules. Confirm the current details in FSA Handbook Volume 5 before writing them into procedure.

The withdrawal date you use here must match the effective date you report to NSLDS — see NSLDS Enrollment Reporting.

The deadlines

R2T4 runs on unforgiving clocks, all counted from the date of determination:

• Return of unearned funds: no later than 45 days after the date of determination. This is the deadline auditors test first, because it is objective: date of determination on one line, return transaction date on another.
• Post-withdrawal disbursement (PWD): if the student earned more aid than was disbursed, the school owes the student a PWD. Grant funds (including Pell) that are due must be disbursed within the Handbook's PWD timeframe — 45 days from the date of determination for grant disbursements; loan PWDs require the borrower's affirmative confirmation after a written offer. Since many clock-hour students are Pell-only, PWD processing is not an edge case — a student who withdraws after completing a payment period's hours and weeks but before the second disbursement posts may be owed money.
• The calculation itself must be performed for every Title IV recipient who withdraws, even when the result is "100 percent earned, nothing to return."

Late returns are a serious finding. A pattern of missing the 45-day deadline can trigger a letter-of-credit requirement and escalated oversight — it is treated as a signal of administrative incapability, not a paperwork slip.

Where clock-hour R2T4 goes wrong

• Using completed hours instead of scheduled hours in the numerator.
• Attendance records that cannot establish a defensible last date of attendance.
• Missing unofficial withdrawals entirely, so no calculation is ever run.
• Confusing the payment period's total hours with the program's total hours in the denominator — the calculation is per payment period (see Payment Periods and Disbursements for how those are defined).
• Failing to pay PWDs, or paying them without the required documentation.
• Missing the 45-day return deadline because the date of determination was recorded late.

Each error is mechanical, which means each is checkable — auditors re-run your math from your own records. The defense is a worksheet (or software output) on file for every withdrawal, with the schedule, attendance record, and return transaction attached. The basics of the clock-hour framework these calculations sit on are covered in Pell Grants at Clock-Hour Schools.

What to do now

1. Audit your last ten withdrawals: re-derive each earned percentage from scheduled hours and confirm the numerator was scheduled — not completed — hours.
2. Check the 45-day deadline on the same ten files: date of determination versus actual return transaction date, with evidence for both.
3. Verify your unofficial-withdrawal sweep: confirm a routine (at least aligned to your attendance-review cycle) that catches students who stopped attending without notice within the required timeframe.
4. Reconcile withdrawal dates against NSLDS for the same students — the two systems must tell the same story.
5. Put FSA Handbook Volume 5 next to your worksheet and re-verify the PWD steps and current timeframes before your next withdrawal, rather than relying on procedure documents written years ago.
