Types of Student Loans: Federal, Private, and Subsidized vs. Unsubsidized

The Two Main Categories: Federal and Private Loans

Student loans fall into two broad categories: federal loans, made through government programs, and private loans, issued by banks, credit unions, or other non-government lenders.

Federal loans generally come with more favorable terms and conditions, such as fixed interest rates and a variety of borrower protections. Private loans can be more flexible in borrowing limits but often lack the safety nets that federal loans provide. Understanding these differences is the first step in choosing which type fits your situation.

• Federal loans: issued by the U.S. Department of Education, fixed rates, no credit check for most loans, and access to income-driven repayment and forgiveness programs.
• Private loans: issued by banks and other lenders, may have fixed or variable rates, require a credit check, and typically do not offer the same repayment flexibility.

Federal Student Loans: What’s Available

Federal loans are the most common starting point for borrowers. They fall into several types, each designed for different student populations and needs.

For most federal student loans, a credit check is not required, and a cosigner is generally not needed. Interest rates are fixed, and you don’t have to begin repaying until after you graduate, leave school, or drop below half-time enrollment.

There are three main types of federal loans for students and parents: Direct Subsidized Loans, Direct Unsubsidized Loans, and Direct PLUS Loans. Each has distinct eligibility rules, interest structures, and borrowing limits.

• Direct Subsidized Loans are available only to undergraduates who demonstrate financial need.
• Direct Unsubsidized Loans are available to undergraduate and graduate students regardless of financial need.
• Direct PLUS Loans include Parent PLUS Loans and, until recently, Graduate PLUS Loans for graduate or professional students.
• Federal loans have borrowing limits, while private loans may allow you to borrow up to the full cost of attendance minus other aid received.

Subsidized vs. Unsubsidized Loans

The word “subsidized” refers to who pays the interest that accrues on the loan while you’re in school or during certain other periods. This is one of the most important differences between federal loan types.

With a Direct Subsidized Loan, the government pays the interest while you are enrolled at least half-time, during the six-month grace period after you leave school, and during any deferment periods. Because of this subsidy, these loans are only available to undergraduates who can show financial need.

Direct Unsubsidized Loans, on the other hand, begin accruing interest from the day the loan is disbursed, even while you are in school or during a grace period. You are responsible for all interest that accrues, though you can often choose to pay it as you go or let it capitalize, which increases the total amount you owe.

Private student loans are never subsidized; the borrower is responsible for all interest that accrues from the start.

• Subsidized: government pays interest during school, grace period, and deferment.
• Unsubsidized: interest accrues from disbursement; borrower pays all interest.
• Private: never subsidized.
• Subsidized loans are only for undergraduates with financial need; unsubsidized loans are available to both undergrads and graduate students.

Direct Subsidized Loans: Details and Limits

Direct Subsidized Loans are a form of federal aid for undergraduate students who can demonstrate financial need. Eligibility is determined by the information you submit on the Free Application for Federal Student Aid (FAFSA).

The government pays the interest on these loans during the periods described above, which can result in significant savings over the life of the loan.

There are annual and aggregate borrowing limits for subsidized loans. These limits vary based on your dependency status and academic level, and the total amount you can borrow in Direct Subsidized and Unsubsidized loans combined is capped by the federal government. For current figures, consult the official StudentAid.gov loan limits page.

• Interest is paid by the government during eligible periods.
• Only for undergraduates with financial need.
• Aggregate limits apply to combined subsidized and unsubsidized borrowing.
• Subsidized portion is capped separately; check current federal limits.

Direct Unsubsidized Loans: Who Can Use Them

Direct Unsubsidized Loans are open to both undergraduate and graduate students, and there is no requirement to demonstrate financial need. This makes them a common option for graduate and professional students, who are not eligible for subsidized loans.

Interest begins to accrue from the date the loan is first paid out, and you are responsible for all of it. Borrowers who are enrolled at least half-time have the option to request a deferment, but interest will still accrue during that period.

There are aggregate borrowing limits for unsubsidized loans, which vary by academic level and dependency status. Federal limits are set by the government and may change, so it's important to verify current amounts on official sources.

• Available to undergraduates, graduate, and professional students regardless of need.
• Interest accrues from the disbursement date.
• Aggregate limits apply to total unsubsidized borrowing; check current federal limits.

Direct PLUS Loans: For Parents and Graduate Students

Direct PLUS Loans are federal loans available to parents of dependent undergraduate students. Parent PLUS loans are taken out in the parent’s name, not the student’s, and the parent is responsible for repayment.

Graduate PLUS Loans were previously available to graduate or professional students, but as of July 1, 2026, new Graduate PLUS Loans are no longer being originated. The program is scheduled to end on July 1, 2028.

PLUS loans require a credit check, unlike other federal loans. Eligibility is not based on financial need, but borrowers with an adverse credit history must meet additional requirements, such as obtaining an endorser.

You can borrow up to the cost of attendance minus any other financial aid you receive. PLUS loans carry a higher interest rate than other federal loans and are unsubsidized, meaning interest accrues from the time the loan is disbursed.

• Parent PLUS loans are available to parents of dependent undergraduates and are in the parent's name.
• Graduate PLUS Loans are no longer available to new borrowers as of July 1, 2026; the program ends July 1, 2028.
• Credit check required; financial need is not a factor.
• Loan amount may cover the full cost of attendance minus other aid.

Private Student Loans: Features and Trade-offs

Private student loans are provided by non-government lenders, including banks, credit unions, and online companies. They often serve as a supplement after federal loans have been exhausted.

Unlike federal loans, private loan approval is generally based on your creditworthiness. If you have limited credit history, you may need a cosigner. Interest rates can be fixed or variable, and they are often higher than federal rates, sometimes exceeding 18%. Many private lenders require payments while you’re still in school, though some offer deferment options.

Private loans rarely offer income-driven repayment or forgiveness programs, and you typically have fewer consumer protections. On the other hand, private loans can fill gaps when the cost of attendance exceeds federal borrowing limits.

• Credit check required; cosigner may be needed for students without credit history.
• Fixed or variable interest rates that can be higher than federal loans.
• Typically require payments in school, though some lenders allow deferment.
• Generally no income-driven repayment or forgiveness options.

How to Choose Between Federal and Private Loans

The best choice depends on your individual circumstances, but here are the main decision criteria to consider:

Start with federal loans because they offer fixed interest rates, flexible repayment plans, and protections like deferment and forbearance. The more favorable terms and conditions can be a deciding factor for many borrowers.

Consider private loans only after you’ve exhausted federal borrowing limits or if you have a strong credit history that could secure a competitive private rate.

Check whether you have access to subsidized loans, as those can be the most cost-effective. Remember that graduate students are not eligible for subsidized loans.

Review the interest rates and fees carefully. Federal rates are set annually for the academic year, while private rates depend on your credit score and market conditions.

• Max out federal loans first to take advantage of consumer protections.
• If you need additional funds, compare private lenders and watch for variable rates.
• Note whether you qualify for subsidized loans, which save money on interest.
• Understand the repayment flexibility: federal income-driven plans vs. private lenders that generally lack them.
