Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for United States change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

The interest saving is straightforward arithmetic. What matters more is what is given up. Federal loans carry income-driven repayment plans, forgiveness programmes including public service forgiveness, deferment and forbearance rights, and discharge on death or disability. A private refinance replaces all of that with a commercial contract, and there is no route back. For a borrower with a stable high income and no forgiveness prospect the trade can be sound; for anyone who might need those protections it usually is not.

the arithmetic is simple; what it omits is what refinancing a federal loan permanently forfeits

Method and limits

What it assumes

  • Both loans held to their stated terms.

What it deliberately does not model

  • The forgiveness value depends entirely on your career path and cannot be estimated generically.
  • Variable rate refinances carry rate risk the comparison does not show.
  • This is a comparison, not advice on whether to refinance.

Frequently asked questions

Can I undo a refinance?
No. Once a federal loan is refinanced privately the federal protections are gone permanently. There is no mechanism to convert a private loan back.
When does refinancing make sense?
A stable high income, no realistic forgiveness prospect, and a meaningful rate reduction. Anyone who might need income-driven repayment should think hard first.
