Shortening Extended Repayment Schedules

Adding extra monthly principal to an extended 25-year plan combines lower mandatory payment flexibility with faster debt retirement.

Frequently Asked Questions

Why enroll in extended repayment if prepaying?

It provides a lower mandatory minimum payment during financial downturns while allowing larger voluntary payments when cash flow permits.

Are there prepayment charges on 25-year terms?

No, federal student loans permit penalty-free prepayments at any time.

How much interest can prepaying save?

Prepaying an extended loan can eliminate tens of thousands of dollars in interest charges.

Will extra payments advance the monthly due date?

Request that servicers keep your regular billing schedule active and apply overpayments directly to principal.
