Federal and Private Student Loans: Comparing the Basic Obligations

Two loans can pay the same tuition bill while offering very different repayment terms. Before borrowing, identify the lender, when interest begins, and what protections are tied to the loan type. Use the amount needed for your education and the repayment obligation as separate questions, rather than treating an available loan limit as a spending target.

The questions below use selected Consumer Financial Protection Bureau guidance, adapted and organized by Fynoptic. Source links and the dates displayed by those sources are provided at the end.

What student loan option is best for me: federal student loans or private student loans?

If you must take out student loans, federal student loans are the best option for the vast majority of borrowers since they have fixed interest rates and more protections.

It is best to max out your federal student loan options before you borrow any private student loans. Federal student loans usually carry more flexible protections if you run into difficulty in repaying your loans, and all new federal student loans have fixed interest rates, meaning the rate does not change over the life of your loan. Private student loans may have variable interest rates, which can reset every month or quarter, causing your monthly payments to change.

Every student’s situation is different. Consult with your school’s financial aid office for additional information.

Graduate PLUS eligibility and federal borrowing limits changed beginning July 1, 2026. Some existing borrowers may qualify for limited exceptions. Compare only the federal options actually available for your loan history and program; do not rely on an older description of unlimited graduate PLUS borrowing. Ask the financial aid office for a written explanation of the applicable limits and verify it with Federal Student Aid.

How much should I borrow in student loans?

If you have to take out student loans, try to only borrow what you need to cover the cost of your education. A good guideline is to limit your borrowing to what your future earnings will allow you to repay; however, this might not be possible for all students.

When deciding how much you should borrow in student loans, it helps to start with a budget for not only the school year but for your total expected time in school. For each additional year that you are in school and take out student loans, your total debt will continue to increase.

If possible, try not to accumulate more total student debt than you expect to earn as a starting annual salary when you leave school. This might not be feasible for all students.

Check out our web tool, Your financial path to graduation, to explore salaries for different programs and majors and what you might expect to earn after graduation. This tool will help you understand your financial aid offer and access the full cost of college. It will also help you estimate how much you’ll owe and determine if you can afford that debt.

More tips about student debt

You are not obligated to borrow the maximum loan amount that you’re offered. Depending on your circumstances and your work earnings and other income, try to borrow just enough to fully pay for your tuition, housing, and other expenses. Some students who don’t have access to other financial support may want to consider taking out the maximum loan amount offered; however, that might not be the right call for all borrowers.

Keep track of how much you are borrowing. As you continue to borrow additional student loans each year you are in school, keep track of your total student debt. Maintain your own copy of all documents and transaction entries. The definitive source for your current loan balances on all of your federal student loans is the U.S. Department of Education’s Federal Student Aid website. Through this website, you can access information about your federal student loans. Your college financial aid office or your lender will have more information about your private student loan balances.

Of course, you can consider many other factors specific to your individual circumstances when determining how much debt you can handle. This is a personal decision that only you can make. You may also want to consider discussing it with your family and other trusted advisors. Learn more about the different ways to pay for college.

What is a federal Direct Loan?

A Federal Direct Loan is a student loan made directly by the U.S. Department of Education.

There are four types of Direct Loans:

  • Direct Subsidized Loans are given to undergraduate students who demonstrate financial need. You won’t pay or collect interest while you are in school and during the grace period after you leave school. The Department of Education pays the loan’s interest on your behalf during that time.
  • Direct Unsubsidized Loans are available to eligible undergraduate and graduate students and are not based on financial need. Interest accrues while the borrower is in school.
  • Direct PLUS Loans include parent PLUS loans and graduate PLUS loans made under applicable eligibility rules. New graduate PLUS borrowing was generally eliminated beginning July 1, 2026, with limited exceptions for eligible existing borrowers; parent PLUS borrowing is subject to new limits and possible exceptions. Check the current rules for your circumstances.
  • Direct Consolidation Loans are a combination of some or all your federal student loans into a single loan with one loan servicer.

You can check to see what type of loan you have through the U.S. Department of Education .

What is a subsidized loan?

For all subsidized federal student loans, the U.S. Department of Education subsidizes—pays the interest on—your loan while you are in school and during periods of deferment, such as during military service.

Subsidized loans are usually federal student loans. Federal subsidized loans are given to undergraduate students who demonstrate financial need. You will be notified by your school if you qualify for a subsidized loan, after you complete the Free Application for Federal Student Aid (FAFSA) . If you have already filed the FAFSA, check with your financial aid office for any additional paperwork that you must submit to obtain a federal loan.

Loan repayment start six months after you graduate, leave school, or drop below half-time enrollment status. During the six-month grace period you will receive the repayment information from your student loan servicer. If you are unable to afford your student loan payment, contact your student loan servicer right away and ask about a deferment or change to your repayment plan.

How does interest accrue while I am in school?

For subsidized federal student loans, your interest is paid by the U.S. government while you’re in school. For most other loans, interest continues to accrue, so you will owe more than you borrowed by the time you leave school.

Interest accrued while you’re in school can be “capitalized,” meaning it is added to your loan’s unpaid principal balance. When capitalization occurs, you are charged interest on interest.

For a hypothetical private loan that capitalizes interest at the end of its grace period, borrowing $5,000 at a 10% annual rate for a 12-month program would accrue about $500 during school and another $250 over a six-month grace period. Adding that $750 to principal would produce a $5,750 balance on which later interest is calculated. This illustration explains capitalization; it is not a statement that every federal loan capitalizes at the end of a grace period.

Capitalization happens only at the events specified for the particular loan and repayment arrangement. Those rules can change and differ between federal and private loans. Review Federal Student Aid's current explanation of interest and capitalization for federal loans, and ask a private lender for the relevant contract provision. Interest accrual and capitalization are separate: an amount can remain unpaid interest without yet being added to principal.
