Student loans are not one product. A federal Direct Loan and a private loan from a bank can have the same interest rate on paper and behave completely differently when you lose your job, go back to school, or decide to work in public service. Understanding that difference before you borrow is worth more than shopping for a tenth of a percentage point.
This guide explains how federal and private student loans work in 2026, what each costs, which protections you give up when you borrow privately, and how to choose a repayment plan that does not eat your paycheck.
Federal loans: the four main types
| Loan | Who can borrow | Need-based? | Key feature |
|---|---|---|---|
| Direct Subsidized | Undergraduates with financial need | Yes | Government pays interest while in school |
| Direct Unsubsidized | Undergraduates and graduate students | No | Interest accrues from disbursement |
| Grad PLUS | Graduate and professional students | No | Borrow up to cost of attendance |
| Parent PLUS | Parents of dependent undergraduates | No | Credit check, higher fee and rate |
Subsidized loans are the best deal available to undergraduates: no interest accrues while you are enrolled at least half-time, during the grace period, and during deferment. Unsubsidized loans accrue interest from the day they are disbursed, which capitalizes when repayment begins.
Interest rates and fees
Federal student loan rates are set by Congress and reset every July 1 for new loans. The rate is fixed for the life of the loan. For recent award years, undergraduate Direct Loans have been in the mid-6% range, graduate loans in the high-7% range, and PLUS loans near 9%. Always confirm the current rate at studentaid.gov before borrowing.
Origination fees are deducted from each disbursement:
- About 1.06% for Direct Subsidized and Unsubsidized Loans
- About 4.23% for PLUS loans
That means a $10,000 PLUS loan disburses roughly $9,577, and you repay the full $10,000 plus interest. The fee is easy to miss because it never appears as a separate charge.
Borrowing limits
| Borrower | Annual limit | Aggregate limit |
|---|---|---|
| Dependent undergraduate | $5,500–$7,500 | $31,000 |
| Independent undergraduate | $9,500–$12,500 | $57,500 |
| Graduate student | $20,500 unsubsidized | $138,500 including undergraduate |
| PLUS | Cost of attendance minus other aid | No aggregate limit |
These limits are the reason many students end up with private loans: federal aid does not always cover the full cost of attendance, especially at expensive private colleges.
Repayment plans
Federal loans offer options that private lenders do not:
- Standard: fixed payments over 10 years, usually the cheapest total cost.
- Graduated: lower payments initially, rising every two years.
- Extended: up to 25 years for balances above a threshold, which lowers the monthly payment and increases total interest.
- Income-driven repayment: payments based on income and family size, with forgiveness of the remaining balance after a set period.
Income-driven repayment has been in flux. The SAVE plan was blocked by litigation, and new legislation introduced a replacement plan for future borrowers. The details depend on when you borrowed and which plan you are enrolled in. Check your servicer's portal and studentaid.gov rather than relying on older guides, including parts of this one.
The consistent principle: income-driven plans protect you when your income is low, but they can stretch repayment for decades and increase the total interest paid.
Public Service Loan Forgiveness
PSLF forgives the remaining balance on federal Direct Loans after 120 qualifying monthly payments made while working full-time for a qualifying employer, such as a government agency or a 501(c)(3) nonprofit.
The requirements are strict:
- Only Direct Loans qualify. FFEL loans must be consolidated.
- Payments must be made under a qualifying repayment plan.
- Employment must be certified, ideally every year.
- Payments made while in deferment or forbearance generally do not count.
PSLF is the strongest argument against refinancing federal loans into a private loan. Once you refinance, the loans become private and PSLF eligibility is gone permanently.
Private student loans
Private loans come from banks, credit unions, and online lenders. They are credit-based, which means most undergraduates need a cosigner. Rates can be fixed or variable, and they depend on credit history, income, and the lender's underwriting.
What private loans usually do not offer:
- Income-driven repayment
- PSLF or federal forgiveness programs
- Subsidized interest
- Deferment on the same terms as federal loans
- Death or disability discharge on federal terms
What they can offer: a lower rate for borrowers with excellent credit, larger amounts when federal limits are exhausted, and faster approval.
When a private loan makes sense
Only after you have exhausted federal aid, including grants, work-study, and Direct Loans. A private loan can be reasonable if:
- The amount needed is small and the rate is genuinely lower than the PLUS alternative.
- You have a creditworthy cosigner and a fixed rate you can afford.
- You have a plan to repay within a defined period.
- You are not pursuing PSLF or another federal forgiveness program.
It rarely makes sense to borrow privately for a degree with weak earnings prospects, or to finance living expenses beyond a modest budget.
Refinancing: the trap to understand
Refinancing replaces existing loans with a new loan at a lower rate. For private loans, it can save real money. For federal loans, it converts them to private debt and permanently removes federal protections.
Before refinancing federal loans, ask:
- Am I likely to need income-driven repayment if my income drops?
- Could I qualify for PSLF or another forgiveness program?
- Do I need the federal deferment and forbearance options?
- Is the rate reduction large enough to justify giving those up?
If the answer to any of the first three is yes, do not refinance. The monthly savings are not worth the lost insurance.
How to borrow responsibly
- Borrow only what you need. Every dollar borrowed today is a dollar plus interest not available for a house, a car, or retirement.
- Estimate your first-year salary and keep total debt below roughly your expected annual income.
- Pay the interest on unsubsidized loans while in school if you can, to prevent capitalization.
- Use the grace period to build an emergency fund, not to postpone planning.
- Sign up for autopay for the 0.25% interest discount many servicers offer.
- Check your credit report before applying for private loans, and fix errors first.
If you are already struggling
Contact your servicer before you miss a payment. Federal loans offer deferment, forbearance, and income-driven plans. Default has serious consequences, including wage garnishment, loss of eligibility for new aid, and damage to your credit.
For private loans, ask about hardship programs. They are less standardized, but many lenders prefer a modified payment to a default.
Frequently asked questions
Should I always choose federal loans first?
Almost always. They offer protections and repayment options that private loans do not, even when the rate is slightly higher.
Can I discharge student loans in bankruptcy?
It is possible but difficult, requiring an undue hardship showing. Recent guidance has made the process somewhat more consistent, but it is still an exception.
Do student loans affect my credit score?
Yes. On-time payments help; late payments and defaults hurt. Federal loans are reported to the bureaus.
Can my parents take out loans for my education?
Yes, through Parent PLUS loans. They are in the parent's name and are the parent's legal obligation.
What happens if I drop below half-time enrollment?
Your grace period may begin, and interest may start accruing. Check with your school's financial aid office before changing enrollment status.
Bottom line
Federal loans are not cheap, but they come with insurance that private loans do not: income-based payments, forgiveness programs, and hardship options. Exhaust them before borrowing privately, and think carefully before refinancing them away.
Borrow less than you can afford to repay, know your expected salary, and choose a repayment plan before the grace period ends. The decisions you make in the first year after graduation determine whether the loan is a manageable tool or a decade-long burden.

How loan servicers work
The Department of Education owns federal loans, but private companies service them. Your servicer handles billing, payment plans, deferment requests, and forgiveness paperwork. Servicers change, sometimes without much notice, and the transfer can cause payment errors.
Keep your own records: loan balances, disbursement dates, payment history, and every form you submit. If a servicer loses a payment or miscounts qualifying months for PSLF, your documentation is the only reliable defense.
Check your loans at studentaid.gov, not just on the servicer's site. The federal database is the authoritative record of who owns and services each loan.
Consolidation, explained
A Direct Consolidation Loan combines multiple federal loans into one. It can simplify payments and make FFEL loans eligible for PSLF, but it also resets the clock on certain forgiveness programs and can increase the total interest paid.
Consolidation is not refinancing. The interest rate becomes a weighted average of the existing rates, rounded up to the nearest eighth of a percent, and it remains a federal loan with federal protections.
| Action | Effect on protections | Effect on rate |
|---|---|---|
| Consolidation | Keeps federal protections | Weighted average |
| Refinancing | Removes federal protections | New private rate |
Forgiveness programs beyond PSLF
There are several smaller programs: Teacher Loan Forgiveness for teachers in low-income schools, state repayment assistance programs for health professionals, and employer tuition assistance that is not a loan at all.
Income-driven repayment also leads to forgiveness after 20 or 25 years, though the forgiven balance may be taxable depending on the tax rules in effect at the time. The tax treatment has changed before and can change again.
Building a repayment budget
- List every loan with its balance, rate, and servicer.
- Calculate the standard 10-year payment for each.
- Compare that total with your expected take-home pay.
- Choose the plan that keeps the payment below roughly 8% to 10% of gross income.
- Pay extra on the highest-rate loan if you have room.
- Reassess every year and after any income change.
The goal is not the lowest possible payment; it is a payment you can sustain for the full term without borrowing to cover it.
If you cannot pay
Contact the servicer before the due date. Federal options include deferment, forbearance, and income-driven plans. Interest may continue to accrue, but the damage to your credit is avoidable.
Default begins after roughly 270 days of nonpayment and brings collection costs, wage garnishment, and loss of eligibility for new aid. It is far easier to prevent than to undo.
How to compare two loan offers
Two offers with the same interest rate can cost very different amounts. Compare four numbers:
| Number | What it tells you |
|---|---|
| Interest rate | The cost of borrowing, before fees |
| Origination fee | Deducted upfront; raises the effective rate |
| Total interest paid | The dollar cost over the full term |
| Monthly payment | What your budget must absorb |
A loan with a 6% rate and a 4% origination fee can cost more than a loan at 6.5% with no fee, depending on the term. Ask each lender for the total cost of credit, not just the APR headline.
Also check the repayment term. Stretching a loan from 10 to 20 years lowers the monthly payment and can nearly double the total interest. A lower payment is not automatically a better deal.
Cosigners and what they are agreeing to
A cosigner is equally liable for the debt. If the borrower stops paying, the lender can pursue the cosigner without first exhausting collection efforts against the borrower. The cosigner's credit is affected by late payments, and the debt counts against their debt-to-income ratio when they apply for their own loans.
Ask the lender about cosigner release. Some allow it after a set number of on-time payments; many do not. If release is not available, the cosigner should understand that the obligation may last for the full term.
What happens if you transfer schools or change majors
Federal aid eligibility depends on satisfactory academic progress and enrollment status. Changing majors can extend your time to degree and your borrowing. Dropping below half-time can trigger repayment on some loans after the grace period.
Talk to the financial aid office before making a change that affects enrollment. A five-minute conversation can prevent a payment starting while you are still in school.
