Frequently Asked Questions

What is the current federal student loan interest rate?

For 2024–2025, undergraduate Direct Loans are 6.53% and graduate/professional loans are 8.08%. Grad PLUS loans are 9.08%. These rates are set each July 1 based on the 10-year Treasury note.

Should I pay off student loans or invest?

If your rate is below 5%, investing in an index fund historically wins long-term. Above 7%? Paying off debt is the guaranteed return. Between 5–7% is a judgment call based on your risk tolerance and whether you have an employer 401(k) match to capture first.

How much does an extra $100/month save?

On a $30,000 loan at 6.53%, paying $440/mo instead of $340/mo saves roughly $3,200 in interest and pays off the loan 2 years early. Use the extra payment field above to calculate your exact savings.

Is forgiven student loan debt taxable?

Under current law, PSLF forgiveness is tax-free. Income-driven repayment (IDR) forgiveness (SAVE, IBR) is also tax-free through 2025 under the American Rescue Plan, but this provision expires in 2026 unless extended. Always verify with the IRS or a tax professional before counting on tax-free forgiveness.

What is the SAVE plan?

SAVE (Saving on a Valuable Education) replaced the REPAYE plan. Your payment is 5% of discretionary income — defined as income above 225% of the federal poverty line. For a single borrower earning $50,000 in 2025, that's about $185/month. Balances may be forgiven after 10 years (if original balance ≤$12,000) or up to 25 years.

Who qualifies for PSLF?

You must work full-time for a qualifying employer (federal, state, local government, or most nonprofits), be on an income-driven repayment plan, and make 120 qualifying payments. The remaining balance is then forgiven tax-free.
