What a student loan is and how it differs from other debt

A student loan is money borrowed specifically to pay for education—tuition, fees, room and board, books—that you repay over time with interest. Unlike credit cards or personal loans, student loans have lower interest rates, longer repayment timelines, and rules built around your income and employment status. The federal government or private lenders provide the money; you sign a contract agreeing to repay it.

The key difference: federal student loans have fixed interest rates set by Congress, income-based repayment options, and forgiveness programs in some cases. Private student loans work more like traditional loans—the lender sets the rate based on your credit, and repayment terms are fixed regardless of your income. Federal loans also pause during economic hardship; private loans do not.

Student loans also differ from grants and scholarships, which do not require repayment. If you have borrowed money, you owe it back. If you received a grant or scholarship, you do not.

Key Takeaways

  • Federal student loans come from the U.S. Department of Education and have fixed interest rates, income-based repayment plans, and potential forgiveness programs; private loans come from banks or credit companies and have rates based on your credit score.
  • You begin repaying federal loans six months after you graduate, leave school, or drop below half-time enrollment—a period called the grace period.
  • Federal loans offer four main repayment plans based on your income, while private loans typically require a fixed payment regardless of what you earn.
  • If you default on a federal loan, the government can garnish your wages, tax refunds, and Social Security; private lenders can sue you and report to credit bureaus.
  • Federal loans may be forgiven after 20 to 25 years of payments under income-driven plans, or after 10 years if you work in public service.

Federal loans versus private loans: the main structural differences

Federal student loans are issued by the U.S. Department of Education. The interest rate is the same for everyone and is set by Congress—currently between 5% and 8% depending on the loan type and year borrowed. You do not need a credit check to may have access to. The government does not require you to begin repayment until six months after you leave school (the grace period), and you can pause payments if you face financial hardship through deferment or forbearance.

Private student loans come from banks, credit unions, or online lenders. The interest rate depends on your credit score and co-signer's credit, if you have one. You may be required to begin repayment while still in school, or when ready after graduation. There is no grace period, and there are no income-based repayment options. If you face hardship, the lender decides whether to work with you—they are not required to.

Most undergraduate borrowers start with federal loans because they are cheaper and more flexible. Private loans are often used to cover costs federal loans do not, or by graduate students who have exhausted federal borrowing limits.

How repayment works and when it begins

Federal loans enter repayment six months after you graduate, leave school, or enroll below half-time status. During this grace period, interest still accrues on unsubsidized loans, but you do not have to make payments. After the grace period ends, you choose a repayment plan and your monthly payment is calculated based on that plan.

The standard federal repayment plan is 10 years with a fixed monthly payment of roughly $100 to $200 per $10,000 borrowed, depending on the interest rate. If you cannot afford that, you can switch to an income-driven plan: your payment is calculated as a percentage of your discretionary income (usually 10% to 20%), and the payment amount changes if your income changes. Income-driven plans extend repayment to 20 or 25 years.

Private loans typically require repayment to begin within six months of graduation and do not offer income-based options. Your monthly payment is fixed for the life of the loan and does not adjust if you lose income or face hardship.

You can change federal repayment plans at any time by contacting your loan servicer—the company that collects your payments. You cannot change a private loan's terms unless you refinance with a different lender, which requires a new credit check and resets the loan clock.

What happens if you stop paying

Missing a federal student loan payment has serious consequences. After 90 days of missed payments, the loan is reported to credit bureaus and your credit score drops. After 270 days (nine months), the loan enters default. Once in default, the entire remaining balance becomes due when ready, and the government can garnish your wages, intercept your tax refunds, and in some cases garnish Social Security payments.

The government can also sue you to recover the debt, and you become responsible for court costs and collection fees on top of the original loan amount. A defaulted federal loan stays on your credit report for seven years from the date of default, making it harder to borrow for a car, home, or credit card.

If you are struggling to pay, you can request deferment or forbearance before you miss a payment. These options pause your payments temporarily (usually up to three years) without counting as a default. You must contact your loan servicer to request either option; they do not happen automatically.

Private loan default works similarly: missed payments damage your credit, the lender can sue you, and they can garnish wages if they win a judgment. However, private lenders cannot garnish Social Security or tax refunds. Private loans also do not have deferment or forbearance options, so your only recourse is to negotiate directly with the lender or refinance.

Income-driven repayment plans and forgiveness

Federal loans offer four income-driven repayment plans: Income-Based Repayment (IBR), Pay As You Earn (PAYE), Revised Pay As You Earn (REPAYE), and Income-Contingent Repayment (ICR). Each calculates your monthly payment as a percentage of your discretionary income—the difference between your gross income and 150% to 225% of the federal poverty line for your family size. Your payment can be as low as $0 per month if your income is below the poverty line.

The trade-off: lower monthly payments mean slower repayment and more interest paid over time. If you do not pay off the loan within 20 to 25 years (depending on the plan), the remaining balance is forgiven. However, forgiven amounts may be treated as taxable income, meaning you could owe federal income tax on the forgiven amount in the year it is forgiven.

Public Service Loan Forgiveness (PSLF) is a separate program: if you work full-time for a government agency or nonprofit organization and make 120 may have access to payments (10 years) under an income-driven plan, the remaining balance is forgiven tax-free. You must be employed in public service when you make the payments and when the loan is forgiven.

Private loans do not offer income-driven repayment or forgiveness programs. Once you borrow from a private lender, you repay the full amount or refinance.

How interest accrual works and why it matters

Interest on a student loan accrues daily based on the outstanding balance and the interest rate. On a federal loan, interest accrues whether you are in school or in repayment. On subsidized federal loans (available only to undergraduates with financial need), the government pays the interest while you are in school and during the grace period. On unsubsidized loans, interest accrues from day one.

Unpaid interest capitalizes—it gets added to your principal balance—at specific points: when you leave school, when the grace period ends, or when you exit deferment or forbearance. Once interest capitalizes, you pay interest on the interest, which increases the total amount you owe.

For example: if you borrow $30,000 in unsubsidized loans at 6% interest and do not make payments for four years (while in school), roughly $7,400 in interest accrues. When you enter repayment, that $7,400 capitalizes, and your new balance is $37,400. You now pay interest on $37,400, not $30,000.

Private loans also accrue interest daily, and unpaid interest capitalizes. Some private lenders allow interest-only payments while you are in school to prevent capitalization; others do not.

Refinancing and consolidation: when and why

Consolidation and refinancing are different tools. Consolidation combines multiple federal loans into one federal loan with a single payment. You do not get a lower interest rate—the new rate is the weighted average of your old rates, rounded up. Consolidation is useful if you have many loans and want one payment, or if you want to access income-driven repayment or PSLF. Once you consolidate, you lose any benefits tied to the original loans (like teacher forgiveness programs).

Refinancing means taking out a new loan from a private lender to pay off your old loans. If your credit score has improved since you borrowed, you may may have access to for a lower interest rate. The trade-off: you lose federal protections like income-driven repayment, deferment, forbearance, and forgiveness programs. Refinancing makes sense only if you have stable income, good credit, and do not plan to use federal safety nets.

You can consolidate federal loans at any time through the Federal Student Aid website. You can refinance federal or private loans through private lenders; the process is similar to explore for any other loan and takes one to two weeks.

Frequently Asked Questions

Can I get a student loan forgiven if I work in public service?

Yes, through Public Service Loan Forgiveness (PSLF). You must work full-time for a government agency or nonprofit organization, make 120 may have access to monthly payments under an income-driven repayment plan, and the remaining balance is forgiven tax-free. You must be employed in public service when you make the payments and when forgiveness is granted. The program has strict rules about what counts as may have access to employment and may have access to payments.

What is the difference between deferment and forbearance?

Both pause your federal loan payments temporarily. With deferment, the government pays the interest on subsidized loans; interest still accrues on unsubsidized loans but does not capitalize. With forbearance, interest accrues on all loans and capitalizes when forbearance ends. Forbearance is easier to obtain but more expensive long-term. You must request either option before you miss a payment.

If I refinance my federal loans, can I get them back to federal status later?

No. Once you refinance federal loans with a private lender, they become private loans permanently. You cannot convert them back to federal loans. This is why refinancing is a one-way decision—make sure you do not need federal protections before you refinance.

How much can I borrow in federal student loans?

Borrowing limits depend on your year in school and whether you are a dependent or independent student. Undergraduates can borrow $5,500 to $7,500 per year in federal loans (total of $31,000 for dependent students, $57,500 for independent students). Graduate students can borrow up to $20,500 per year with no aggregate limit. Private lenders set their own limits based on your credit and income.

Will my student loan debt affect my ability to get a mortgage?

Yes. Lenders look at your debt-to-income ratio—the percentage of your monthly income that goes to debt payments. High student loan payments can lower the amount you can borrow for a home. However, student loans are viewed more favorably than credit card debt because they are installment loans with fixed payments. Making on-time payments helps your credit score and shows lenders you manage debt responsibly.
