What are the differences between subsidized and unsubsidized student loans?

Federal loans are the go-to funding source for the majority of college students. According to recent data from the Education Data Initiative, nearly 52% of matriculating undergrads rely on federal loans at some point during their college careers. It makes sense: federal funding tends to come with generous borrower protections and lends to almost everyone, regardless of credit score.

However, before you borrow money from the federal government, you’ll need to know what type of federal loan you’re interested in. The U.S. Department of Education offers two main types of loan to undergraduate borrowers: Subsidized and Unsubsidized Loans. Not all borrowers are eligible for both. Those who are will need to choose carefully. Here’s a look at the key differences between Subsidized vs. Unsubsidized student loans, as well as some important pros and cons to consider.

What’s the difference between Direct Subsidized and Unsubsidized student loans?

Both Subsidized and Unsubsidized Loans are part of the federal Direct Loan Program, but they have some key distinctions. The main difference is when interest starts accruing and who is responsible for paying it.

For Direct Subsidized Loans, the U.S. Department of Education pays the interest that accrues on your loans during college and during the six-month grace period after a student graduates. You’ll never have to worry about paying this interest, which makes Subsidized Loans the less expensive option. The perks continue after graduation, too; the federal government will also pay your interest for you during any future deferment periods. (Keep in mind that with forbearance periods, interest will continue to accrue no matter what type of loan you have.)

For Direct Unsubsidized Loans, interest begins accruing on the loans as soon as they are taken out. That means you’ll be on the hook for interest charges while you’re in school as well as during your post-graduation grace period. If you don’t pay this interest before the grace period ends, it will capitalize, or get added to the principal amount of your loan. That can make your loan more expensive in the long run.

Here are some other key differences to consider:

Subsidized Loans

These are need-based; you must demonstrate financial need to qualify.

Only available to undergraduate students.

The government pays, or subsidizes, the interest on the loan while you’re in school, during your grace period, and during any other deferments.

Subsidized Loans have stricter annual and aggregate loan limits. Both independent and dependent undergrads are subject to the same borrowing limits.

What are the similarities between Direct Subsidized Loans and Direct Unsubsidized Loans?

Both Direct Subsidized Loans and Direct Unsubsidized Loans are designed to help students cover the cost of higher education. Here are a few key similarities.

Eligibility: The application process is the same for both types of loan. Simply fill out the Free Application for Federal Student Aid (FAFSA) each year. Your school’s financial aid office will review your form, decide how much federal aid you qualify for, and send you a financial aid letter with those details.

Loan fees: Both loan offerings come with the same origination fee. Your total loan fee is calculated as a percentage of the loan amount you take out. This fee is built into your monthly payment. (You can check current fees on the federal Student Aid website.)

Interest rates: Both Subsidized and Unsubsidized undergraduate student loans have the same fixed interest rate. This rate is set at the beginning of each school year and changes from year to year. (The federal government’s current interest rates are published each July.)

Pros and cons of Subsidized Student Loans

Here are some of the key benefits and drawbacks of Subsidized Loans

Pros of Subsidized Loans:

• Unlike Direct PLUS Loans, there’s no credit check required for a federal Direct Subsidized Loan. That means you can apply with any kind of credit score and still get the same fixed rate as everyone else.

• The U.S. Department of Education pays the interest on your Subsidized Loans so long as you maintain at least half-time enrollment.

• The government pays your interest during the six-month grace period after you graduate.

• The government pays your interest during any period of deferment.

Cons of Subsidized Loans:

• Subsidized Loans have lower annual borrowing limits than Unsubsidized Loans.

• Students won’t qualify if they can’t demonstrate financial need.

• Graduate and professional students don’t qualify for Direct Subsidized Loans.

• Independent undergraduate students can’t qualify for any more Subsidized funding than dependent students can.

Pros and cons of Unsubsidized Student Loans

Unsubsidized loans also have their own distinct advantages and disadvantages.

Pros of Unsubsidized Loans:

• There’s no credit check required to apply. That means you won’t have to worry about getting denied or needing a cosigner.

• Undergraduate, professional, and graduate students all qualify for Direct Unsubsidized Loans.

• Students don’t need to demonstrate financial need to apply.

• Aggregate and annual loan limits are slightly higher for Unsubsidized Loans. As a result, students can sometimes borrow more than the actual cost of their tuition in order to cover fees and other education-related expenses.

• Independent students can qualify for extra Unsubsidized funding, which can provide more financial breathing room in the absence of a contributing parent.

Cons of Unsubsidized Loans:

• They’re still subject to strict borrowing limits.

• Borrowers are responsible for paying all accrued interest, and interest accrual starts as soon as the loan is issued.

• You’re responsible for making interest payments during all future deferment periods.

How much can you borrow with federal student loans?

Your school determines how much you can borrow in federal Subsidized and Unsubsidized Loans. They make this calculation based on a number of factors, such as the cost of attendance, your year in school, and your dependent status. Your school also must abide by federal loan limits. Students are only allowed to borrow up to a certain amount from the federal government each year (called an annual loan limit). They also have to abide by a lifetime borrowing cap, called an aggregate limit. You can view current annual and aggregate borrowing limits on the federal student aid website.

If you’ve already borrowed up to your loan limit, you can take out additional federal loans through the Direct PLUS Loan program. These loans include Parent PLUS Loans, available to the parents of dependent undergraduate students, and Graduate PLUS Loans, available to graduate and professional students. PLUS Loans require a credit check and higher fees. PLUS Loan interest rates also tend to be higher. However, they let you borrow up to the full cost of attendance.

Like Unsubsidized and Subsidized student loans, PLUS Loans are eligible for federal deferment, forbearance, and other flexible repayment options. You can also consolidate federal loans to make them eligible for income-driven repayment plans, longer loan terms, and some loan forgiveness programs.

How do you apply for federal student loans?

Here are step-by-step instructions on how to apply for federal Direct Loans:

1. Fill out the FAFSA online. First-year students will need to fill out the full FAFSA, while sophomores, juniors, and seniors can fill out a FAFSA renewal form each subsequent academic year.

2. Your school’s financial aid office will mail or email a financial aid award letter to summarize your available financial aid. This letter will include details about federal loans and other grant and work-study programs based on your eligibility and financial need.

3. Accept the financial aid and student loans by contacting your school’s financial aid office.

4. Review and sign any paperwork to secure your financial aid, such as the Master Promissory Note (MPN) for loans.
