College costs often exceed what grants, scholarships, savings, and work can cover, and many students turn to loans to fill the gap. The two main sources are the federal government and private lenders such as banks, credit unions, and online lenders. Understanding federal vs private student loans before you borrow is essential, because the type of loan you choose affects your interest rate, your monthly payment, and the protections you will have if money gets tight after graduation. This guide explains the key differences, recent changes to federal loan limits, and a sensible order for borrowing.
How federal student loans work
Federal student loans are made through the William D. Ford Federal Direct Loan Program. To get them, you file the FAFSA and accept the loans listed in your school’s financial aid offer. The main types are:
- Direct Subsidized Loans for undergraduates with financial need. The government pays the interest while you are enrolled at least half time, during the grace period, and during deferment.
- Direct Unsubsidized Loans for undergraduate and graduate students regardless of need. Interest accrues from disbursement.
- Direct PLUS Loans for parents of dependent undergraduates (Parent PLUS), which require a check for adverse credit history but not a minimum credit score. Grad PLUS loans for graduate students are being phased out for new borrowers under the 2025 budget reconciliation law.
Federal interest rates and fees
Federal loan interest rates are fixed for the life of each loan and are set each year by a formula tied to the 10-year Treasury note auction in May, plus a fixed add-on that differs by loan type. Every borrower of the same loan type in the same year gets the same rate, regardless of credit. Federal loans also carry an origination fee deducted from each disbursement, which is higher for PLUS loans.
Federal borrowing limits
Undergraduates face annual and aggregate limits that depend on year in school and dependency status. Dependent first-year students, for example, can borrow far less in federal loans than the full cost of many colleges. The 2025 law also introduced new limits for graduate and professional students and caps on Parent PLUS borrowing for loans first disbursed on or after July 1, 2026, with transition rules for students already enrolled. Check StudentAid.gov for the limits that apply to you.
How private student loans work
Private student loans are offered by lenders under their own terms. Key features include:
- Credit-based approval and pricing. Lenders review credit history, income, and debt. Most undergraduates lack the credit history to qualify alone and need a creditworthy cosigner.
- Fixed or variable rates. Rates vary by lender and borrower. Variable rates can rise over time.
- Borrowing up to cost of attendance. Many lenders allow borrowing up to the school-certified cost of attendance minus other aid.
- Lender-specific repayment options. Some lenders offer in-school deferment, interest-only payments, or limited forbearance, but protections vary widely.
Federal vs private student loans: side-by-side
| Feature | Federal loans | Private loans |
|---|---|---|
| Credit check | None for students; adverse credit check for PLUS | Yes, often requires cosigner |
| Interest rate | Fixed, same for all borrowers | Fixed or variable, based on credit |
| Subsidized interest | Available for undergrads with need | Not available |
| Income-driven repayment | Available | Generally not available |
| Forgiveness programs | PSLF and others | Rare |
| Death and disability discharge | Yes | Varies by lender |
| Deferment and forbearance | Defined federal options | Lender policies vary |
Repayment flexibility
Federal loans offer protections private loans generally cannot match. Borrowers can choose among repayment plans, including income-driven options that tie payments to income. The 2025 law created the Repayment Assistance Plan and set new rules for borrowers taking out loans after July 1, 2026, while existing borrowers face transitions out of some older plans. Federal loans also offer deferment for situations such as unemployment and economic hardship, and forbearance in other circumstances.
Private lenders may offer some hardship forbearance, but terms are set by each lender and are usually shorter and less generous.
Forgiveness and discharge
Federal loans can qualify for Public Service Loan Forgiveness after 120 qualifying payments while working full time for a qualifying employer, Teacher Loan Forgiveness for eligible teachers in low-income schools, and forgiveness after a set number of years under income-driven plans. Federal loans are discharged upon the borrower’s death, and borrowers with a total and permanent disability can apply for discharge.
Private loans rarely offer forgiveness. Many private lenders now discharge loans upon death or disability, and federal law requires private lenders to release a cosigner upon the student’s death for loans made after November 2018, but you should read each lender’s policy.
When private loans might make sense
Private loans can be appropriate in limited situations:
- You have exhausted federal loan limits and still have a gap.
- You or your cosigner have excellent credit and the lender’s rate is meaningfully lower than the federal rate, and you are confident you will not need federal protections.
- You are a graduate student affected by new federal borrowing caps.
Even then, compare offers carefully and borrow only what you need.
A sensible borrowing order
- Free money first: grants, scholarships, and tuition waivers.
- Savings and income: family savings, 529 plans, and earnings from work-study or part-time jobs.
- Federal subsidized loans.
- Federal unsubsidized loans.
- Parent PLUS or private loans, compared carefully.
How to compare private student loan offers
- APR, which includes fees, rather than the interest rate alone.
- Fixed vs variable rate, and how high a variable rate can go.
- Repayment term, since longer terms lower monthly payments but increase total interest.
- In-school repayment options.
- Cosigner release, including how many on-time payments are required.
- Hardship options, such as forbearance and modified payments.
- Death and disability discharge policies.
Many lenders offer prequalification with a soft credit check, which does not affect your credit score. Shopping for rates within a short period limits the effect of hard inquiries on scoring models.
Understanding cosigner risk
A cosigner is equally responsible for the debt. Late payments affect both credit reports, and the lender can pursue the cosigner for the full balance. Before cosigning, parents and relatives should consider whether they can afford the payments if the student cannot, and whether cosigning could affect their own borrowing for retirement or a home.
Refinancing considerations
Borrowers can later refinance federal or private loans into a new private loan, possibly at a lower rate. Refinancing federal loans into a private loan, however, permanently gives up federal benefits such as income-driven repayment and PSLF. Refinancing private loans to a better rate carries less trade-off.
Estimating what you can afford
A common guideline is to keep total student loan debt below your expected first-year salary in your field. Use the Department of Education’s loan simulator to estimate monthly payments under different plans, and research typical starting salaries for your intended career. Borrowing less in the first place is the most effective way to keep repayment manageable.
Reading the master promissory note
Before receiving federal loans, borrowers sign a Master Promissory Note and complete entrance counseling at StudentAid.gov. These steps explain your rights and obligations, including when repayment begins and what happens if you fall behind. Private lenders have their own loan agreements and must provide disclosures, including an application disclosure, an approval disclosure, and a final disclosure, under federal truth-in-lending rules. Private education loan rules also give you a cancellation period after the final disclosure during which you can cancel the loan without penalty. Read each document carefully and keep copies.
Frequently Asked Questions
Can I get federal student loans with bad credit?
Yes. Direct Subsidized and Unsubsidized Loans do not require a credit check. PLUS loans require that the borrower not have an adverse credit history.
Are private student loans dischargeable in bankruptcy?
Both federal and private student loans are difficult to discharge in bankruptcy and require showing undue hardship, although courts and the government have updated approaches in recent years. Consult a bankruptcy attorney.
Should I choose a fixed or variable rate?
Fixed rates provide predictable payments. Variable rates may start lower but can rise. Borrowers with long repayment horizons often prefer fixed rates.
Can I consolidate private loans with federal loans?
You cannot include private loans in a federal Direct Consolidation Loan. You can refinance both into a private loan, but federal loans would lose their federal protections.
