Student Loans: Federal vs Private in Plain English
A plain-English starter guide to student loans for students and families: how federal and private loans compare, the FAFSA, capitalization, repayment, and forgiveness.
A student loan is money you borrow to pay for college, then pay back later. There are two big buckets: federal student loans (from the U.S. government) and private student loans (from a bank, credit union, or online lender). They look similar at first. They behave very differently when life gets hard.
This is a plain-English starter guide for students and families. For a feel for how a payment fits into your money, our budget calculator can help you sketch the numbers. For more on borrowing in general, see interest rate and APR in the glossary, and the Learn hub for related topics.
Federal student loans, in one minute
Federal student loans come from the U.S. Department of Education. You apply for them by filling out the FAFSA (Free Application for Federal Student Aid) at studentaid.gov. Most students qualify for at least some federal aid.
Two common types:
- Direct Subsidized Loans — for undergraduates with financial need. The government pays the interest while you are in school.
- Direct Unsubsidized Loans — for undergraduates and grad students. Interest builds up the whole time, including in school.
The U.S. Department of Education sets the interest rate every year by law, and it is the same for every borrower with that loan type that year. There is no credit check for most undergrad federal loans, and there is no co-signer.
Private student loans, in one minute
Private student loans come from a bank, credit union, or online lender. The lender decides the rate based on your credit (or your co-signer's). Most undergrads need a co-signer because they do not have a credit history yet.
Private loans are real loans like any other consumer loan. Federal Student Aid (FSA) protections do not apply to them.
The protections that come with federal loans
This is the big difference. Federal loans come with rights private loans usually do not match:
- Income-driven repayment plans — the monthly payment is capped as a percentage of your income, with options that drop the payment to as low as $0 in lean months.
- Deferment and forbearance — official ways to pause payments during unemployment, hardship, or going back to school.
- Loan forgiveness programs — including Public Service Loan Forgiveness (PSLF) for certain government and non-profit jobs after 10 years of qualifying payments.
- Death and disability discharge — federal loans are forgiven if you die or become totally and permanently disabled. Most private loans are not.
The official site for all of these is studentaid.gov, run by Federal Student Aid (FSA). The Consumer Financial Protection Bureau (CFPB) also has a free Student Loan Resource Center.
When private loans can make sense
Private loans are not bad — they are just different. They can fit when:
- You have hit your federal loan cap and still have a real funding gap.
- You (or your co-signer) have strong credit, so the rate is competitive.
- You understand that the federal protections above will not apply.
Most financial aid offices recommend exhausting federal aid first, then looking at private loans only to fill what is left. The U.S. Department of Education and CFPB both repeat this guidance.
Interest, capitalization, and "going up while you sleep"
Most student loans charge interest from day one. While you are in school (or in the six-month grace period after), unpaid interest can be capitalized — added to your loan balance, so you start paying interest on the interest. This is why a $20,000 loan can become a $24,000 loan before you graduate.
Federal subsidized loans are an exception: the government pays the interest while you are in school. Federal unsubsidized loans and most private loans do not get that treatment.
What the monthly payment usually looks like
The standard repayment plan is 10 years. On a $20,000 federal loan at a 6% rate, the standard payment is about $222 per month. Income-driven plans can lower it. Refinancing private loans at a lower rate can lower it. Stretching the term lowers it but raises total interest paid.
The Federal Student Aid Loan Simulator at studentaid.gov walks through every payment plan with your real numbers.
What to do before signing anything
A short pre-flight checklist:
- Fill out the FAFSA every year you are in school. It costs nothing, and it is the only way to qualify for federal aid.
- Borrow the smallest amount you can live on. Future-you will thank past-you.
- Read the Master Promissory Note before signing. It is the contract.
- Understand the difference between subsidized, unsubsidized, and private interest treatment.
- Know who your loan servicer is — that is the company you will mail payments to. The CFPB has a list of every federal servicer.
What if you are already struggling
If a payment is unaffordable or you have fallen behind, call your servicer first and ask about income-driven repayment, deferment, or forbearance. Federal loans have built-in safety nets. Ignoring them is the worst move — defaulting can lead to wage garnishment and loss of refunds. The CFPB has a free guide for borrowers in trouble.
A note on advice
This is general information, not advice. Many high schools, colleges, and non-profit credit counselors offer free FAFSA help — use them. For private loan decisions, talk to a fee-only financial planner or a HUD-certified counselor. The wrong loan choice at 18 can shape your finances for a decade.
Numbers and rules in this article change every year — always check the latest from the IRS, CFPB, and your state's insurance / consumer protection department.
Common questions
What is the FAFSA?
The FAFSA (Free Application for Federal Student Aid) is the form you fill out every year to apply for federal student loans, grants, and work-study. It is free at studentaid.gov. Most students qualify for at least some federal aid, and many states and colleges use the FAFSA to award their own aid too.
Should I take federal or private student loans?
Most aid offices and the CFPB suggest using federal loans first because they come with built-in protections — income-driven repayment, deferment, forbearance, and forgiveness programs — that private loans usually do not match. Private loans can fill a gap once federal aid is maxed out, but read the contract carefully.
What is loan capitalization?
Capitalization is when unpaid interest gets added to your loan balance, so you start paying interest on the interest. This commonly happens at the end of school or grace periods on unsubsidized federal loans and most private loans. It is why a $20,000 loan can grow to $24,000 before you make your first real payment.
What is income-driven repayment?
Income-driven repayment plans cap your monthly federal student loan payment at a percentage of your discretionary income. In low-income months the payment can drop to as little as $0. After 20-25 years of qualifying payments, any remaining balance is generally forgiven. The Loan Simulator at studentaid.gov walks through your real numbers.
What happens if I cannot make a student loan payment?
For federal loans, call your servicer first and ask about income-driven repayment, deferment, or forbearance. Ignoring the loan is the worst move — federal loans in default can lead to wage garnishment and lost tax refunds. The CFPB has a free guide for borrowers in trouble at consumerfinance.gov.
