Student Loan Refinance Calculator

A lender's calculator shows the money saved. It will not tell you that refinancing federal loans is permanent. You hand over forgiveness, payments that fall when you earn less, and the right to pause if you lose your job. This shows both halves.

What you owe now

A percentage per year. Use a balance-weighted average if you have several.

Why your own figure may differ

Your lender quotes a different total. Fees vary, and some are folded into the loan rather than billed.
Your first payment is part month. Interest from the day you draw the money is charged separately.
Your balance already includes fees. Check what the loan was written for, not what you asked for.

What you would be giving up

What each term does to the deal

A longer term makes the payment smaller. It does not make the loan cheaper.

Common questions about refinancing student loans

Should I refinance my student loans?

If they are private loans, and you can get a lower rate, usually yes. There is little to lose. If they are federal loans, stop and think. Refinancing turns them into a private loan for good. You can never turn them back. You give up payments that fall when you earn less, forgiveness, and the right to pause if you lose your job. A lower rate can still be worth it. But only once you know what you are handing over.

What exactly do I lose by refinancing federal loans?

Five things, and they are gone for good. Payments that fall when you earn less. Forgiveness if you work for a government or non-profit. The right to pause if you lose your job. Forgiveness of anything left at the end of a federal plan. And a write-off if you die or become disabled. This tool lists them next to your saving, so you can weigh both.

How much do I need to save for it to be worth it?

There is no single number. It depends what you are giving up. For private loans, any real saving is worth having. For federal loans, ask a harder question. Is the saving worth more than an insurance policy you can never buy back? If your job is secure and your pay is steady, that insurance is worth less to you.

Will a longer term make it cheaper?

It makes the payment smaller, not the loan cheaper. Stretching the term nearly always means more interest overall, even at a lower rate. The tool shows both numbers side by side, so the trade is out in the open.

Can I refinance just some of my loans?

Often yes, and it is worth doing. Refinance the private ones. Leave the federal ones alone. You keep the protections where they matter, and take the saving where it costs you nothing.

Does applying hurt my credit score?

Checking your rate usually does not. Most lenders do a soft check first. Applying does leave a mark. Several lenders in a short window normally count as one, so compare offers close together.
