What happens when you take out a student loan
A student loan is money a lender gives you to pay for education. You receive the funds, use them for tuition or living expenses, and then repay the money over time with interest. The lender — which may be the federal government or a private bank — expects you to pay back more than you borrowed because interest accrues on the outstanding balance.
The basic sequence is: you borrow, you attend school, you enter repayment, you make monthly payments until the loan is paid off. The timeline from first disbursement to final payment typically spans 10 to 25 years, depending on the loan type and repayment plan you choose.
Key Takeaways
- Federal student loans come from the U.S. Department of Education and have fixed interest rates set by Congress; private loans come from banks and credit unions with rates that vary by lender and your credit history.
- Interest begins accruing immediately on unsubsidized loans but does not accrue while you are in school on subsidized federal loans.
- You do not repay while enrolled at least half-time, but interest on unsubsidized loans continues to grow and gets added to your balance.
- Repayment plans range from 10 years (Standard) to 20 to 25 years (income-driven), and your monthly payment amount depends on which plan you select.
- If you do not repay, the loan enters default, which damages your credit, triggers wage garnishment, and can prevent you from getting future federal loans.
Federal loans versus private loans
Federal student loans are issued by the U.S. Department of Education. The interest rate is set by Congress and is the same for all borrowers in a given year — for example, all Direct Unsubsidized Loans issued in 2024 have the same rate. Federal loans include Direct Subsidized Loans (interest does not accrue while you are in school), Direct Unsubsidized Loans (interest accrues from day one), and Direct PLUS Loans (for parents or graduate students). You do not need a credit check to may have access to for federal loans.
Private student loans come from banks, credit unions, and online lenders. The interest rate depends on your credit score and the lender's policies — two borrowers can receive very different rates for the same loan product. Private loans require a credit check and often a cosigner if you have limited credit history. Interest accrues immediately, and you typically must begin repayment while still in school, though some lenders offer in-school deferment.
Federal loans offer more flexibility: income-driven repayment plans, deferment and forbearance options, and loan forgiveness programs. Private loans rarely offer these protections. Most borrowers start with federal loans because they are cheaper and safer.
How interest and fees work
Interest is the cost of borrowing money. If you borrow $10,000 at 5% interest, you owe $10,500 after one year (assuming simple interest; actual calculation is more complex). On federal loans, interest accrues daily based on your outstanding balance and the annual interest rate.
Federal loans also charge an origination fee, which is a percentage of the loan amount deducted before you receive the funds. For Direct Loans, this fee is currently 1.085% to 1.1% depending on loan type. If you borrow $10,000, you receive roughly $9,891 and owe $10,000 back. Private loans may or may not charge origination fees; check your promissory note.
On unsubsidized loans, unpaid interest can be capitalized — added to your principal balance — when you enter repayment or at other trigger points. This means you then owe interest on the interest, which increases the total amount you repay. On subsidized federal loans, the government pays the interest while you are in school, so capitalization does not happen during enrollment.
The in-school period and grace periods
While you are enrolled at least half-time, you do not make loan payments. This is called the in-school deferment period. However, interest behavior differs by loan type: on subsidized loans, the government covers the interest, so your balance does not grow. On unsubsidized loans, interest accrues and accumulates. When you leave school, unpaid interest on unsubsidized loans is capitalized into your principal.
After you graduate, leave school, or drop below half-time enrollment, you enter a grace period — typically six months for federal loans — during which you do not have to make payments. Interest still accrues on unsubsidized loans during this time. At the end of the grace period, repayment begins automatically unless you have requested deferment or forbearance.
Private loans handle grace periods differently. Some offer six months; others offer none. Check your promissory note to see what applies to your loan.
Repayment plans and monthly payments
Once repayment begins, you choose a repayment plan that determines your monthly payment amount and how long you repay. The Standard Repayment Plan for federal loans is 10 years with a fixed monthly payment — currently around $100 to $150 per $10,000 borrowed, though this varies with interest rates. You pay the same amount every month.
Income-driven repayment plans — Revised Pay As You Earn (REPAYE), Pay As You Earn (PAYE), Income-Based Repayment (IBR), and Income-Contingent Repayment (ICR) — calculate your payment as a percentage of your discretionary income. If your income is very low, your payment may be $0. These plans extend repayment to 20 or 25 years. Any remaining balance is forgiven at the end, though forgiveness may be taxable income.
Private loans typically offer only a standard 10-year plan or a graduated plan (payments start low and increase). You cannot switch to an income-driven plan with a private loan.
What happens if you do not repay
If you miss a payment, your loan enters delinquency. After 90 days of missed payments, the delinquency is reported to credit bureaus, damaging your credit score. After 270 days (nine months) of non-payment, federal loans enter default. Private loans may default sooner depending on the lender's terms.
Once in default, serious consequences follow: your entire remaining balance becomes due immediately (called acceleration); the federal government can garnish your wages without a court order; your tax refunds are seized; and you become ineligible for future federal student aid. Default also makes it nearly impossible to get a mortgage, car loan, or credit card.
If you cannot afford payments, contact your loan servicer before you miss one. Federal loans offer deferment, forbearance, and income-driven repayment as alternatives to default. Private lenders may offer forbearance but have fewer options.
Loan forgiveness and discharge
Federal student loans can be forgiven or discharged under specific circumstances. Public Service Loan Forgiveness forgives remaining balances after 120 may have access to payments while working for a government agency or nonprofit. Teacher Loan Forgiveness forgives up to $17,500 for teachers in low-income schools after five years of service. Income-driven repayment plans forgive any remaining balance after 20 to 25 years of payments.
Loans can also be discharged (forgiven without repayment) if you become permanently and totally disabled, if the school closes while you are enrolled, or if you are defrauded by the school. Discharge due to disability requires medical documentation. Discharge due to school closure or fraud requires you to submit a form to your loan servicer.
Private loans do not offer forgiveness programs. Discharge is rare and typically requires proof of fraud or school closure.
Frequently Asked Questions
Do I have to start repaying immediately after graduation?
No. You have a grace period — usually six months for federal loans — before repayment begins. During this time, you do not make payments, though interest on unsubsidized loans continues to accrue. After the grace period ends, your first payment is due unless you have requested deferment or forbearance.
What is the difference between deferment and forbearance?
Both pause your payments temporarily. In deferment, interest on subsidized federal loans does not accrue; on unsubsidized loans, it does. In forbearance, interest accrues on all loan types. Deferment is usually for specific circumstances (returning to school, economic hardship); forbearance is more widely available. Both are temporary — typically 6 to 12 months — and must be renewed if you need continued relief.
Can I pay off my loan early without a penalty?
Yes, for federal loans. You can pay extra toward principal at any time with no prepayment penalty. For private loans, check your promissory note — some charge a prepayment penalty, though this is becoming less common. Paying extra reduces the total interest you owe and shortens your repayment timeline.
What happens to my loan if I go back to school?
If you re-enroll at least half-time, your federal loans return to in-school deferment status and payments pause. Interest on subsidized loans stops accruing; interest on unsubsidized loans continues. When you leave school again, you enter another grace period. Private loans may or may not offer this option — contact your lender to ask.
Can student loans be forgiven if I declare bankruptcy?
Student loans are rarely discharged in bankruptcy. You must prove "undue hardship," a legal standard that is difficult to meet. Courts typically require you to show you cannot maintain a minimal standard of living, that your situation is likely to persist, and that you have made good-faith repayment efforts. Consult a bankruptcy attorney if you are considering this route.
