Student loans are used by millions of people to attend colleges and universities in the United States. As of 2023, Americans had $1.78 trillion in outstanding federal and private student loan debt, and more than 45 million borrowers had federal student loans.

Student loans are one of the most flexible and beneficial types of loans, but they are also one of the most complex. So, there’s a lot that future, current, and former college students should know about how student loans work, how they are repaid, and more.

How do student loans work?

How do student loans work?

Student loans are designed to help students (and their parents) at colleges and universities cover the cost of attendance to obtain a degree or certificate. There are several different types of student loans, some offered by government agencies and some by private lenders. Student loans consist of a lender allowing you to borrow money in exchange for the promise of repayment, with interest.

In many cases, student loans are paid directly to the college or university, and any overage can then be distributed to the borrower. Additionally, student loans often have borrowing limits. In the case of federal direct loans, student loans have annual maximums that depend on the student's year in school and dependent status, while other types of loans may only be limited by the school's published cost of attendance.

Types of student loans

Types of student loans

There are two main categories of student loans: federal and private. Federal student loans refer to any student loan originated by the U.S. Department of Education, while private loans refer to student loans made by a financial institution, such as a bank or other lender.

Within the category of federal student loans, there are several different types. There are four loan types under the Federal Direct Loan program:

  • Direct Subsidized Loans: Made to eligible undergraduate students with financial need. The federal government pays the interest on subsidized loans while the borrower is in school or on a qualified deferment period.
  • Direct Unsubsidized Loans: These loans are made to both undergraduate and graduate students, and there is no requirement for financial need. Interest accrues on direct unsubsidized loans regardless of school enrollment, deferment, or forbearance status.
  • Direct PLUS Loans: PLUS loans are made to parents of dependent students as well as graduate or professional students whose needs aren't met by other financial aid. Unlike subsidized and unsubsidized loans, PLUS loans require a credit check but also aren't limited by anything other than the school's cost of attendance.
  • Direct Consolidation Loans: One thing many borrowers don't understand is that they will receive a separate student loan for every semester (more if they have subsidized or PLUS loans in addition to unsubsidized). Direct Consolidation Loans allow you to combine all of your student loans into one.

How to apply for student loans

How to apply for student loans

With private lenders, the application process for student loans can vary from one lender to the next. But for federal student loans, it is a pretty straightforward process.

1. Complete the FAFSA

Complete and submit the FAFSA, which is the Free Application for Federal Student Aid. This is the form you'll use to qualify for federal loans and grants, as well as several other types of need-based student aid.

2. Review your financial aid offer

You'll receive a financial aid offer from your school based on the information in your FAFSA. This will include any federal student loans for which you qualify.

You can choose to accept the entire amount of student loans you're offered, a reduced amount, or not at all. The financial aid letter you receive will detail the process for accepting student loans.

Cost of Debt

The cost of debt refers to the average cost of borrowing for a business.

3. Sign the promissory note for your loan(s)

The next step is to sign your loan agreement, which essentially is a legal document that says you promise to repay your loans as agreed. You'll also complete "entrance counseling," which will give you some general information about how your student loans work.

Student loan payment pauses

Student loan payment pauses

In certain circumstances, federal student loans can be paused. This can either be specific to you as a borrower or a pause granted to a large group or even all federal student loan borrowers (as happened during the COVID-19 pandemic). Private loans may be able to be paused as well in times of financial hardship, but this depends on the lender.

With federal loans, the two main types of pauses are deferment and forbearance. Both involve temporarily suspending payment obligations, but there are some subtle differences.

A deferment typically requires some sort of reason, such as being enrolled in school or being unemployed. Deferments can last for various lengths of time and must be granted if you have a valid reason. During periods of deferment, interest doesn't accrue on subsidized federal loans.

A forbearance can be granted for as long as 12 months at a time, with no set maximum, and no specific qualification is required. It is up to your loan servicer whether or not to grant forbearance, although it typically is a fairly automatic process. During periods of forbearance, interest will continue to accumulate on all loans.

It's also worth noting that in times of financial hardship, enrolling in an income-driven payment plan (more on these in a bit) can have the same effect. These plans cap your monthly payment at a certain percentage of your discretionary income -- and it could be as low as $0 if you're unemployed or underemployed.

How to repay student loans

How to repay student loans

With federal student loans, there are several different repayment options, and they can be classified into four basic categories.

1. Standard repayment plan

The standard repayment plan is a 10-year repayment plan with a fixed monthly payment. When you graduate (or leave school) and your grace period expires, this is the default repayment option. In a nutshell, if you make monthly payments for 10 years under the standard repayment plan, your loans will be paid off in full at the end of the 10-year period.

2. Graduated repayment plan

The graduated repayment plan is a 10-year repayment plan that has lower initial payments, but its monthly payments increase every two years. It is designed for people who anticipate their earnings to increase significantly during the first several years of their careers.

3. Extended repayment plan

The extended plan has a fixed monthly payment but a longer, 25-year repayment term. It allows borrowers to get a lower monthly payment than under the standard plan.

Interest Rate

An interest rate is the cost of borrowing money or the premium you get for lending money. Learn how interest rates affect the economy.

4. Income-driven repayment plans

The Department of Education offers several different income-driven repayment plans that set the borrower's required monthly payment based on their annual income, loan balance(s), and family size. There are five income-driven plans available to most federal student loan borrowers:

  • Pay As You Earn (PAYE): Only available to new borrowers after Oct. 1, 2007. Limits the monthly payment to 10% of discretionary income.
  • Revised Pay As You Earn (REPAYE): Similar to the PAYE plan, but open to all borrowers with eligible federal direct loans. Payments are limited to 10% of discretionary income, and any outstanding loan balance is forgiven after 20 years (undergraduate) or 25 years (graduate/professional).
  • Income-Based Repayment (IBR): Limits the monthly payment to 10% or 15% of discretionary income, depending on when the borrower's first loan was received, and forgives any remaining balance after 20 or 25 years.
  • Income-Contingent Repayment (ICR): Monthly payments are 20% of discretionary income or the amount of a fixed 12-year repayment plan, whichever is less. Any outstanding balance is forgiven after 25 years.
  • Saving on a Valuable Education (SAVE): The newest income-driven plan, the SAVE plan, caps borrowers' monthly payments at 5% (undergraduate loans) or 10% (graduate) of discretionary income. It also forgives remaining balances after 20 years or 25 years, respectively. The SAVE plan is set to replace the REPAYE plan when it goes into effect.

Income-driven repayment plans are the best option for the vast majority of student loan borrowers. Not only do they typically result in the lowest monthly payments, but borrowers must be enrolled in income-driven repayment to qualify for public service loan forgiveness (PSLF) and several other programs. And, within the realm of income-driven plans, virtually all borrowers will find the lowest payments under the SAVE plan.

5. Private student loan repayment

With private student loans, the repayment options depend on the company that made the loan and its terms. Most private student loans have a set repayment length and do not offer income-driven options, although some may allow you to lengthen your repayment term to lower your payment -- for example, switching from a 10-year to a 15-year repayment term. If you're curious about repayment options for your private student loans, the best course of action is to contact your lender.

1. Scholarships and grants

There are many different scholarships and grants available to help cover the cost of higher education. Some are merit-based, while others are need-based. There are many potential places to look for these programs, but here are some good starting points:

  • Fill out the Free Application for Federal Student Aid (FASFA).
  • Contact your school's financial aid office.
  • Ask your high school guidance counselor.
  • Use the U.S. Department of Labor's scholarship search tool.

2. Work-study/part-time jobs for students

Federal work study provides part-time jobs for students who have financial need. You'll need to apply for aid and qualify for these jobs, and the amount you earn cannot exceed your total work-study award.

Alternatively, students can obtain part-time employment elsewhere to earn money towards the cost of attending school. In most cases, it isn't practical to completely cover the cost of a college degree through part-time jobs, but it can certainly help lower the amount of money you need to borrow.

3. Crowdfunding

Another method of raising money for college is to crowdfund, which means starting a campaign online (usually through social media) to ask for friends, family, and social media followers to contribute funds for a specific purpose. There are several popular crowdfunding platforms, some of which specialize in education funding, so this could be worth looking into as well.

Student loans FAQs

Student loans FAQs

Do student loans go away after 20 years?

angle-down angle-up

Student loans can go away after 20 years under certain conditions. If you are enrolled in certain income-driven repayment plans, such as PAYE or REPAYE, and make required payments for 20 years, any remaining balance on undergraduate loans will be forgiven. On the other hand, if the borrower received any loans for graduate or professional study, the repayment period to qualify for forgiveness is 25 years.

Who is the best to get a student loan from?

angle-down angle-up

For most borrowers, federal direct student loans are the best way to go. However, federal loans have annual and lifetime borrowing limits that might not cover the full cost of attending school. In situations like these, there are private lenders that originate student loans, and these can be worth looking into.

What happens if you never pay your student loans?

angle-down angle-up

When you leave school, there is a six-month grace period before you have to start paying back your student loans or enter into a deferment or forbearance. If you don't set up one of these, or if you have exhausted all available deferment and forbearance periods available, your loans become delinquent as soon as you miss a scheduled payment. After 30 days, you'll start facing late fees, and after 90 days, the delinquency will be reported to the credit bureaus (and can be devastating to your credit score). After 270 days, your federal student loans will enter default. Student loans cannot be discharged in bankruptcy, so you'll still owe the money.
