How the loan is priced

Limits and fee first, then interest and the payment.

Each PLUS loan starts building interest when it is paid out. Deferred until six months after the student leaves school, that interest is added to the balance, and the balance sets the term and the payment.

What a Parent PLUS loan is

A Direct PLUS loan for parents is a federal loan in the parent’s name for a dependent undergraduate’s costs. It needs a credit check for an adverse history, not a score. It can be at most the cost of attendance minus other aid. For loans made on or after July 1, 2026, the 2025 reconciliation law also caps it at $20,000 a year and $65,000 in all for each student, and those loans are repaid on the Standard plan, 10 to 25 years depending on the balance, without the income-based Repayment Assistance Plan.

The fee and interest in deferment

The origination fee, 4.228% for loans first disbursed before October 1, 2026, comes off each disbursement, so the school receives less than the loan amount while the full amount is repaid. Interest starts at each disbursement. Parents can defer payments while the student is enrolled at least half time and for six months after; the interest that builds is then added to the balance. 8.94% is the 2025–26 rate; each award year has its own fixed rate.
