Federal vs. Private Student Loans: Take the Federal One First
A federal student loan carries protections a private one does not — income-driven repayment, deferment, and forgiveness programmes for some careers. A private loan is a commercial contract. Once you sign it, those options are gone.
Key takeaways
- File the FAFSA first, whatever your parents earn. It is how federal aid is allocated, and it is free.
- Federal loans come with repayment protections that private lenders do not offer.
- Private loans price on credit, which at eighteen usually means a cosigner is on the hook with you.
- Refinancing federal loans with a private lender is a one-way door — the federal protections do not come back.
The short answer
Fill in the FAFSA. Take what you are offered federally. Use a private loan only for the gap that is left, and only after you have.
This is not a close call, and it is not about the interest rate. It is about what happens if things go wrong later.
The difference that matters is not the rate
Compare the protections, not the advertised APR. This is the table:
| Federal | Private | |
|---|---|---|
| How you apply | The FAFSA | An application with the lender, priced on credit |
| Credit check | Not required for most undergraduate loans | Yes, and a cosigner is common for students |
| Interest rate | Set by law, the same for every borrower in that year | A range — where you land depends on the credit profile |
| Income-driven repayment | Available | Not offered |
| Deferment if things go wrong | Available under set conditions | At the lender's discretion, if at all |
| Forgiveness programmes | Exist for some careers and circumstances | None |
What a cosigner is actually signing
On a private student loan a cosigner is not a character reference. They are jointly responsible for the debt, it appears on their credit report, and if payments are missed it damages their credit as well as yours.
The way out is called cosigner release, and it usually requires a set number of on-time payments plus a credit check on the student. Whether a lender offers it, and on what terms, is the single most important question to ask before signing — and several lenders do not publish the answer.
Fixed or variable, on a loan this long
Private lenders quote both. The variable rate is almost always the lower-looking number, and it is the one that can move against you for the next ten years.
On a debt you will be repaying into your thirties, a fixed rate is a known quantity and a variable rate is a bet. That is the trade, and it should be made deliberately rather than by picking the smaller number on the page.
Refinancing later: the one-way door
Refinancing swaps what you owe for a new loan at a new rate. On private debt that can save real money.
On federal debt it is permanent. Refinancing a federal loan with a private lender converts it into a private loan and gives up income-driven repayment, deferment and any forgiveness eligibility for good. Read what you would be surrendering before you compare the rate.
Frequently asked questions
Should I file the FAFSA if my parents earn well?
Yes. It is how eligibility for several kinds of federal aid is determined, including loans that are not need-based, and some schools and states use it for their own aid too. It costs nothing to file.
Is a private student loan ever the right choice?
For the gap federal aid does not cover, yes. As a replacement for federal aid you have not applied for, no.
Can I get out of a private student loan in hardship?
Only if the lender agrees. There is no statutory income-driven repayment on a private loan, which is the central reason to exhaust federal options first.
Does my credit score matter for a federal loan?
Not for most undergraduate federal loans, which do not require a credit check. Some federal loans for graduate students and parents do consider adverse credit history.

- Student Loan RAP CalculatorEstimate your monthly payment under the new Repayment Assistance Plan (RAP), and compare it to a standard 10-year repayment.
- Extra Payment CalculatorSee how much you save by paying extra toward your loan principal, and whether to shorten your term or lower your payment.
- Personal Loan CalculatorCalculate your personal loan payment and APR from the amount, interest rate, fees, and term.

Terms used in this guide
- Student eligibility
- Whether the bank offers an account designed for students, usually with the monthly fee waived while you are enrolled and an age limit.
- Origination fee
- What the lender charges to process and underwrite the loan, usually quoted as a percentage of the amount borrowed. It is already baked into the APR, which is why two lenders can quote the same rate and not cost the same.
- Credit score
- The score range an issuer suggests for approval. It is guidance, not a guarantee: income, existing debt and your history with that bank all weigh in.
- Interest rate
- The yearly rate used to calculate the interest portion of your mortgage payment. On its own it tells you what the loan costs to borrow, not what it costs to get.
