Offsetting Graduated Repayment Costs

Because graduated payments start below standard amortizations, extra early payments neutralize interest growth.

Frequently Asked Questions

Why add extra funds to graduated plans?

Extra payments counter early negative or slow amortization before mandatory tier increases take effect.

Are extra payments applied first to interest or principal?

Federal rules require covering accrued monthly interest first; excess amounts go directly to principal.

Does extra principal prevent payment tier increases?

No, scheduled tier adjustments remain unchanged, but the overall loan finishes earlier.

Can prepayments be paused if income drops?

Yes, voluntary extra contributions can be adjusted or stopped without penalties.
