What is the standard student loan repayment term?

10 years is the standard repayment plan for federal student loans. Income-driven plans extend this to 20–25 years but typically cost more in interest.

How much does an extra $100/month save on student loans?

On a $30,000 loan at 6% over 10 years, an extra $100/month saves approximately $1,800 in interest and pays off the loan 1.5 years early.
