Frequently Asked Questions

What is the standard repayment plan?

The standard federal student loan repayment plan spreads payments over 10 years. Income-driven repayment plans (IBR, PAYE, SAVE) can lower monthly payments but extend the repayment period and increase total interest paid.

How much does an extra $100/month save?

On a $30,000 loan at 6.5% interest, an extra $100/month can save over $4,000 in interest and cut 2–3 years off your repayment timeline. Use the extra payment slider to see the exact impact for your loan.

Should I refinance my student loans?

Refinancing federal loans into private loans can lower your interest rate but permanently removes access to federal protections like income-driven repayment and Public Service Loan Forgiveness (PSLF). Refinancing private loans is generally lower risk.
