When refinancing makes sense

If you can lower your rate by 1%+ on a large balance, refinancing typically saves thousands. On $45,000 at 6.8% → 4.5%, you save approximately $7,500 over 10 years.

Warning: federal loan protections

⚠️ Refinancing federal loans into private loans permanently removes access to income-driven repayment, Public Service Loan Forgiveness, and federal forbearance programs.

Break-even calculation

If refinancing has fees, divide fees by monthly savings. That's your break-even in months. If you plan to pay off sooner, refinancing may not be worth it.

⚡ CalcWolf Insight

Average student loan refinance rates in 2026 range from 3.99%–8.5% for well-qualified borrowers. The median federal student loan rate (2025 cohort) is 6.53% — making refinancing potentially attractive for high earners.

Frequently asked questions
Should I refinance my federal student loans?
Only if you have stable income, no plans to use federal programs (PSLF, IDR), and can qualify for a rate at least 1% lower. The tradeoff of losing federal protections is significant.
