When most people think about student loans, they think about the interest rates that are compounded. However, there’s a lot more to know when it comes to student loans and compounding. We’re here to talk all about it and clear up the confusion.

If you’re in the process of repaying your student loans, you’ve probably read (or heard) that student loan interest rates compound. Compounding means that the interest rate on your loan can rise every month or quarter depending on what lender and repayment plan you use. This article will explain how often student loans compound, how this impacts your payments, and when to consider refinancing with a private lender. We will base our discussion today on – How Often Do Student Loans Compound. But, other resources which you can find on our website include some frequently asked questions such as: do student loans compound monthly or yearly and how are student loans compounded

## How Often Do Student Loans Compound

Even though student loan rates are expressed as an annual rate, the interest is usually compounded daily. On a $10,000 loan, you might think that a 4.45% interest rate would mean $445 paid in interest during the year, but that’s not the case.

Instead, your annual rate is divided by 365, to get your daily interest rate. So, in the above example, you’d be charged an interest rate of 0.012% each day. At the end of your first day, your interest charge totals $1.20 and it’s added to the $10,000. On the following day, your interest is calculated on $10,001.20. At the end of the year, you’ll pay a total of $455.02 in interest — providing the lender with an extra $10 just because of the way interest is compounded.

When you consider that this daily compounding takes place over all the years you are in school and beyond, you can see how interest charges lead to repaying so much more than you borrow.

All federal student loans and most private student loans charge simple interest instead of compound interest.

With simple interest, you pay interest only on your principal amount and don’t accrue interest on your unpaid interest. Because of this, you pay less interest over the life of your loan. With each month’s payment, you pay the full amount of interest you owe for that month.

With compound interest, on the other hand, you’ll inevitably pay more interest over time. This is due to the fact that compound interest allows the lender to charge interest on your balance and on unpaid interest that accrues over time.

Do federal student loans ever compound interest?

There are some scenarios where your interest compounds on federal student loans. This is most common during student loan deferment periods where interest accrues on the amount you borrowed while you’re temporarily not making payments. This means that once the deferment period is over, you’ll typically owe more money than you did when you originally requested the pause on loan payments, since that unpaid interest is added to your loan balance.

Unpaid interest can also accrue any time you’re repaying your loans under an income-driven repayment plan and your monthly payment is less than the amount of interest that accrues each month. When unpaid interest is added to your balances owed in either of these situations, the act of increasing the loan balance is referred to as capitalization.

How student loan interest works

Student loan interest is calculated as a percentage of your principal balance. Interest is included in every monthly payment you make. If you have a fixed interest rate, your monthly payment will stay the same each month, though the portion of your payment that goes toward interest decreases with each successive payment. You can see how this works by using a student loan calculator.

How simple interest is calculated

To calculate simple interest, you’ll multiply your outstanding principal balance by the daily interest rate applied to your loan, then multiply that result by the number of days in your payment cycle. To come up with the daily interest rate for your loan, you’ll divide your loan’s interest rate by the number of days in the year.

Say you have a $10,000 loan with an interest rate of 5.28 percent. Here’s how you would calculate your interest payment using simple interest:

Find your daily interest rate: 0.0528 / 365 = 0.000144.

Multiply your daily interest rate by your principal balance: 0.000144 x $10,000 = $1.44.

Multiply your daily interest charge by the number of days in your payment cycle: $1.44 x 30 = $43.20.

This is how much you’ll pay in interest during your first month of repayment. As you pay off your principal, that monthly interest charge will shrink. For example, once you whittle down your principal to $5,000, here’s what the formula looks like:

0.0528 / 365 = 0.000144.

0.000144 x $5,000 = $0.72.

$0.72 x 30 = $21.60.

How compound interest is calculated

While rare, some private student loans use a daily compound interest formula. In this method, accrued interest is continually added to your balance. In the above example, the daily interest charge at the beginning of your repayment period, $1.44, would be added to your balance on day one. The next day, you’d find your daily interest charge by multiplying your daily interest rate by $10,001.44, and so on. Here’s what that looks like:

Day 1: 0.000144 x $10,000 = $1.44.

Day 2: 0.000144 x $10,001.44 = $1.4402.

Day 3: 0.000144 x $10,002.88 = $1.4404.

Day 4: 0.000144 x $10,004.32 = $1.4406.

While the increase to your balance might be only a few dollars, the growth can be exponential the longer your interest goes unpaid.

The bottom line

If you owe money on student loans or plan on borrowing for higher education in the future, you’ll most likely be charged simple interest on your loan balances. This makes it considerably easier to pay down your student debt faster and avoid a situation where your loan balance is climbing faster than you can pay it off. If you want to avoid paying more interest than necessary, you can always make extra payments on your loans and request that they go toward the principal.

College is supposed to be fun, right? Hollywood sure thinks so: in movies like Old School, Legally Blonde and Accepted, it’s one-half wild parties, one-half intellectual and emotional discovery. But that’s Hollywood—the schools themselves paint a different, but equally attractive picture. Open any admissions office pamphlet and you’ll find students lounging cheerfully in grassy campus spaces; friendly, approachable professors chatting with small clusters of adoring undergrads; clean, peaceful dormitories; and constantly perfect weather.

While both of these portrayals contain some truth (there are parties; the weather is nice sometimes), there’s one aspect of college that is often left out, or at least pushed to the sidelines: the price tag. While it’s no secret that getting a degree has grown more expensive in recent years, the numbers are nonetheless surprising. The cost of tuition and fees at public four year institutions increased by 17% over the past five years alone, according to data from The College Board.

Before using the student loan calculator above, come prepared with a few pieces of information about your loan.

### Loan amount

Loan amounts vary depending on whether you’re exploring a federal or private student loan. The loan amount you’re offered might also be limited based on your enrollment level (e.g., undergraduate versus graduate or professional student) or degree program.

#### Federal student loan amounts

**Undergraduate students:**

- Direct Subsidized Loans: Up to $5,500 annually.
- Direct Unsubsidized Loans: Up to $12,500 annually.

**Graduate students:**

- Direct Unsubsidized Loans: Up to $20,500 annually.
- Direct PLUS Loans: Up to the school’s reported cost of attendance, minus other financial aid received.

**Parents of dependent undergraduate students:**

- Parent PLUS loans: Up to the school’s reported cost of attendance, minus other financial aid received.

#### Private student loan amounts

Loan amounts for private student loans can vary by lender. Each lender sets its own borrowing criteria, annual borrowing limits, interest rates and repayment terms. In general, private student loan lenders offer loan amounts that cover the gap between a school’s cost of attendance and any other financial aid a student receives. Some lenders also impose lifetime borrowing limits, which may be up to $150,000 or more for some degrees. Regardless of whether you borrow federal or private student loans, borrow only the amount you need per school year after exhausting all grant and scholarship options. If you must take out loans to finance educational gaps, consider maximizing federal student loan limits before turning to a private student loan, as federal student loans come with additional benefits like income-driven repayment plans and standardized hardship programs.

### Loan term

Your loan term is the amount of time you have to repay the loan in full. For federal student loans under a standard repayment plan, the default loan term is 10 years. However, student loans that are under an alternative payment plan offer terms from 10 to 25 years. Like private student loan amounts, private student loan repayment terms vary by lender. Terms for private student loans can be as short as five years and as long as 20 years. A shorter loan term can help you save more money on interest charges during your repayment period but result in a larger monthly payment. Some lenders offer lower interest rates as an incentive for a short term length. On the flip side, a longer term for your student loans will lower your monthly payment but will accumulate more interest charges over time. Before borrowing student loans, make sure you know all of the term options your lender offers so you can choose the right path for your financial needs.

### Interest rate

The interest rate you’re offered depends on the type of lender you’re pursuing and your financial picture. Federal student loans offer the same interest rate to all borrowers, regardless of credit score or income. Private student loans, on the other hand, will often do a credit check and set interest rates according to your creditworthiness. The higher your credit score, the lower your interest rates. Keep in mind that the lowest interest rates advertised on lender websites may not be available to you. To find out what interest rates you’ll receive, take advantage of lenders’ prequalification features, if available. Prequalification allows you to input basic details about yourself and your desired loan in exchange for a snapshot of the rates and terms offered.

For many students, the only way to stay atop this rising tide has been by taking on an increasing amount of student loans. The result has been skyrocketing student loan debt over the past decade.

Not so fun, that – but don’t get discouraged. Sure, some recent graduates have student loan horror-stories to tell: high debt, low job prospects and a load of other expenses to boot; and others have simply stopped bothering to make loan payments at all (the total number of people with defaulted student loans recently climbed to over 7 million). Many graduates, however, find their debt to be manageable, and, in the long run, worthwhile.

The important thing is to know in advance what you’re getting yourself into. By looking at a student loan calculator, you can compare the costs of going to different schools. Variables like your marital status, age and how long you will be attending (likely four years if you are entering as a freshman, two years if you are transferring as a junior, etc.) go into the equation. Then with some financial information like how much you (or your family) will be able to contribute each year and what scholarships or gifts you’ve already secured, the student loan payment calculator can tell you what amount of debt you can expect to take on and what your costs will be after you graduate – both on a monthly basis and over the lifetime of your loans. Of course how much you will pay will also depend on what kind of loans you choose to take out.

With student loans, borrowers pay a specific amount of money toward the principal of their loan each month, but they’re also charged an extra percentage in the form of interest. In most cases, student loans charge simple interest, which means that you don’t pay interest on your unpaid interest. Here’s what to know about simple versus compound interest and how to calculate each one.

## Do student loans have compound or simple interest?

While the increase to your balance might be only a few dollars, the growth can be exponential the longer your interest goes unpaid.

## When does student loan interest start accruing?

Interest starts accruing on your student loans from the date the lender disburses your loan. This means that while you may not need to make payments on your student loans while you’re in school, interest will accrue.

If you have federal subsidized student loans, the federal government pays any interest that accrues while you’re in school, as well as during future deferment periods. If you don’t have this type of loan, though, the lender or loan servicer will take all the interest that accrues during your deferment and add it to your student loan balance.

If you want to avoid having your interest capitalized, you can make interest-only payments while you’re in school, in your grace period or in a period of deferment.
