When does refinancing student loans make sense?
Refinancing replaces one or more existing student loans with a new private loan, hopefully at a lower rate. Unlike mortgage refis, most student-loan refis come with $0 in application or origination fees, so the break-even is effectively instant if the new rate is lower than your current weighted-average rate.
The catch — and it's a big one — is that refinancing federal loans converts them to private permanently. You lose access to:
- PSLF (Public Service Loan Forgiveness) — 10 years of qualifying public-service payments → balance forgiven. Forfeited the moment a federal loan becomes private.
- Income-driven repayment plans (PAYE, SAVE, IBR, ICR) — payment caps based on your income and family size, with forgiveness after 20-25 years.
- Federal forbearance / deferment — pause payments during unemployment, hardship, military service, school, etc.
- Death & disability discharge on the federal generous terms.
Private-to-private refinancing carries none of this risk — you're giving up nothing because there's nothing federal to lose. If your loans are private and the market rate has dropped meaningfully since you originated, refi is almost always a no-brainer.
For federal loans, the calculation is harder. Refi makes sense when (a) you have stable, high private-sector income, (b) you have no realistic path to PSLF, (c) the rate cut is large enough to materially change your total cost, and (d) you have an emergency fund and strong job security so you don't need federal forbearance.
