Formula

Standard amortizing payment at r = APR ÷ 12

Example

$35,000 at 5.8% over 10 years → about $385/month, roughly $11,150 total interest.

Standard vs extended plans

Longer terms cut payments but raise lifetime cost substantially. Compare totals here before choosing extended or income-driven plans if cash flow allows the standard schedule.

Frequently asked questions

Is refinancing worth it?

If you can beat your current rate without losing federal protections you value, refinancing can save thousands — model the new rate here first.

Do extra payments help?

Yes — additional principal payments shorten the term directly since interest accrues daily on the balance.
