A student loan interest calculator can help you determine how much extra money accumulating on a monthly basis. This will also provide an idea of your total accrued debt, including the principal and accumulated interest.
Interest on student loans is accrued during the period of time that a loan is in default. Interest compounds daily, so it will continue to grow until the loan is paid off or forgiven. If you are already in repayment, interest will be charged at the end of each month.
Student loan interest rates can be a confusing topic. At first glance, student loans are similar to other loans, such as a mortgage or a car loan.
With private student loans, this is almost the case. However, interest rates on federal student loans may differ from other types of loans due to unique subsidies and repayment schedules.
In this guide, we will look at the mechanisms for adjusting interest rates on student loans in different situations. Here’s how student loan interest rates really work.
The details of student loan interest rates depend largely on the differences between simple and compound interest. The rules for accruing interest depend on the type of loan you have and your repayment plan. Let’s see how the calculations work for both types of interest.
In the following examples, we assume that you have a fixed interest rate for your student loans. All federal loans have a fixed interest rate. However, your student loans may have variable interest rates if they were made by a private lender.
Simple interest multiplies the interest rate by the principal amount to determine the amount of interest you must pay each year.
For example, on a $50,000 loan with a 5% simple interest rate, you owe $2,500 per year ($50,000 x .05 = $2,500). And over a 10-year period, a total of $25,000 in interest will have accrued.
For installment loans, such as mortgages, car loans and personal loans, a simple interest rate formula is usually used. As long as you pay the loan as agreed, you will only pay interest on the principal, not on the accrued interest.
Compound interest works differently from simple interest. With compound interest, accumulated interest is added to your balance every month, every day, or at a frequency set by the lender. This is the formula for calculating compound interest:
Compound interest = P [(1 + i)n – 1]
Let us define the different terms of compound interest:
- P for principle
- i means the interest rate
- n is the number of compound periods
Suppose you want to calculate the compound interest on a $50,000 student loan with an annual interest rate of 5%, accruing over 10 years. Here’s how to use the formula above to find that number.
Compound interest = P [(1 + i)n – 1]
$50,000 [(1 + 0.05)10 – 1]
Compound interest = $31,445.
So we see that using compound interest yields $6,000 more interest than using simple interest.
And don’t forget that in our example we assumed that the interest rate would increase annually. With a more frequent dialing schedule, the differences become even more apparent.
Interest on student loans is usually calculated on a daily basis. But before you panic: This doesn’t mean your balance will go up every month (as can happen with credit cards).
If you pay off your federal loans according to the standard 10-year repayment plan or your private loans according to the terms of the loan, your loan balance will only decrease over time and no unpaid interest will accrue.
But what about when you don’t pay your loan, for example during school, during a grace period or during a deferred payment? In many cases, interest continues to accrue during these periods.
When you begin repaying the loan, the interest accrued may be capitalized, meaning it is added to your principal. So you pay interest on the interest from now on.
Repayment plans for federal student loans (IDRs) offer a unique benefit that private loans do not.
In an IDR plan, unpaid interest is not capitalized while you are in the plan. Instead, continuous simple interest is charged on the outstanding principal amount.
This detail is very important. Many borrowers with IDR plans may not even pay enough per year to cover their interest costs. In a typical installment plan, this unpaid interest is capitalized and added to the principal. However, in IDR plans, the annual interest rate does not increase with time.
For example, suppose you have $100,000 in student loans at an annual interest rate of 6.5%. You have a PAYE plan and your monthly payment is $0. In the first year, you earn $6,500 in interest. And that’s exactly the same amount of interest you would have earned in a fifth year.
This means that even if your balance increases, your annual interest expense remains the same.
This means that your effective interest rate will decrease as your student loan balance under the IDR plan increases.
In some situations, students may be eligible for grants that can lower the interest rate on student loans. The two most common types of interest rate subsidies for student loans are:
Some student loans are interest-free for the duration of your studies. For example, with Direct Subsidized Loans, the Department of Education pays the interest on the student loan for you while you are in school and during the six-month grace period.
Only students with a college degree are eligible for subsidized loans. And even students must demonstrate financial need by completing the Free Application for Federal Student Aid (FAFSA) to qualify for the program. Subsidized student loans also have lower debt limits than other federal loan options.
Some loans specifically for certain working students may also offer this benefit. The medical student loan program is a good example. These loans do not begin to accrue interest until after the student has graduated and the one-year grace period has expired.
You will not receive the benefits described above for unsubsidized Direct Loans, PLUS Loans or Consolidated Direct Loans. These student loans earn interest immediately, even though you don’t have to repay them until after you graduate.
This accrued interest will be added to your balance when you begin to repay the loan. You can avoid these potential financial consequences by paying only the interest during your studies.
Some IDR plans also offer interest subsidies on student loans. With the PAYE, IBR and REPAYE plans, the government pays all unpaid interest on your subsidised student loans for the first three years of repayment.
The REPAYE plan is the real star of student loan interest subsidies. For borrowers participating in the REPAYE scheme, the government continues to pay 50% of the outstanding interest on subsidised loans after the initial three-year period has expired. In addition, it still pays half of the outstanding interest on your unsubsidized student loans for all periods.
This particular advantage makes REPAYE a great option for borrowers looking for maximum remission of their IDR student loans. In fact, keep in mind that borrowers with an IDR plan will likely have to pay taxes on the waived amounts.
With REPAYE you can reduce the annual interest on your balance by 50%. And that can have a significant impact on your tax bill for IDR student loan forgiveness.
Student loans generally pay interest on a daily basis.
As you pay off your loans, the amount of interest you pay each month decreases. But during the period of non-payment, interest may be charged on the student loan daily.
The portion of your payment that goes to interest is highest at the beginning of the repayment plan. However, it decreases with time.
Borrowers may accrue unpaid interest during deferral or payment periods. If you have accrued unpaid interest, your payment will be deducted from the principal. Therefore, in some cases, your entire student loan may be used for interest payments.
When repaying a student loan in the normal course of business, it is impossible to completely avoid interest charges. However, borrowers can reduce the interest they pay over the life of the loan by refinancing at a lower rate.
For example, students can also apply during periods of non-payment. B. during deferral and grace periods, pay only interest. This can minimize the capitalization of interest later, when the student graduates and begins to repay the loan normally.
Follow these steps to calculate the interest rate on student loans:
- Divide the annual interest rate by 365 to get the daily interest rate.
- Then you multiply the daily interest rate by the principal amount to get the daily interest cost.
- Then multiply this amount by your billing cycle (usually 30 days).
- Finally, multiply this figure by 12 to get the annual interest cost.
Student loan grants allow borrowers to avoid adding unpaid interest to the principal.
For subsidized direct loans, the Department of Education pays the outstanding interest on behalf of the student. In addition, borrowers can receive an interest subsidy on student loans if they participate in an IDR plan.
Student loan interest rates work like a regular loan, as long as you make your payments (to the government or to a private lender) on a regular schedule. However, there are important differences that other types of debt do not have.
Depending on the repayment plan you use and the amount of your income, you can expect single interest, compound interest or bonus interest.
If you are considering traditional repayment advice, you must understand the unique rules of student loans, or you may be making a mistake.

Student loan interest is calculated by multiplying the interest rate for a specific time frame by the amount of money that you have borrowed. Interest compounds on top of your original principal, so when it compounds, it will be added to the amount you owe. Reference: student loan compound interest calculator.
Frequently Asked Questions
Is education loan interest compounded?
A: Education loans are not compounded.
Does interest continue to accrue on student loans?
A: Sometimes it does, but not always. When the loan is paid off or when you die, interest stops accruing on your student loans until a new payment begins.
Why does my student loan interest keep going up?
A: It is most likely because you are not making the payments on your student loan in a timely manner. The interest rate will always be higher if it goes unpaid for too long.
