Your Ultimate Guide To How Student Loan Interest Works

A borrower’s interest rate may be simple or compound.

The simple interest on a loan is mainly based on the amount you originally borrowed (the amount you took out first).

For example, If a student has a $30,000 student loan and an annual interest rate of 5%, the simple interest due after one year is $1,500 ($30,000 x 0.05).

Depending on the type of loan you took out, your interest rate may differ.

In this article, we’ll break down how is interest calculated on your student loan and how to reduce it with proven ways.

Interest and Compound Interest Calculations

The interest charged on a loan is the sum of money owed to a lender as a consequence of the funding transaction. It’s most often expressed as an annual percentage of the loan amount.

The interest rate charged to a borrower might be simple or compound.

How Simple Interest Is Calculated

The simple interest on a loan is mainly based on the amount you originally borrowed (the amount you took out first).

For example, If a student has a $30,000 student loan and an annual interest rate of 5%, the simple interest due after one year is $1,500 ($30,000 x 0.05).

How Compound Interest Is Calculated

The total loan amount is used to compute compound interest, which is measured on the entire loan amount, including both principal and accrued but unpaid interest (interest charged to the loan but not yet paid).

The idea of compound interest is to charge interest on interest. When the accrued interest isn’t paid off when it comes due, it can be capitalized.

For example, If the loan balance began at $30,000 and interest was capitalized after one year, the new loan balance is $45,500 ($30,000 + $1,500), with interest accrued in year two totaling $2,275 ($45,500 x 0.05).

How Interest Is Calculated on Student Loans and Parent Loans

The daily charge for parent and student loans (PLUS loans) is applied. The following equation is used to calculate the interest accrued:

Interest = Loan Balance x (Annual Interest Rate / Number of Days in Year) x Days in Accrual Period

Subsidized and Unsubsidized Loans

A student loan secured by the federal government is either subsidized or unsubsidized.

Subsidized Student Loan Interest

Interest on Subsidized federal direct loans does not accumulate while the student is in school or during the 6-month grace period after graduation or departure from half-time enrollment.

Keep in mind: Subsidized loans do not accrue interest, but rather the borrower is reimbursed for any interest paid.

The government pays the interest that builds up while the student is in school, as well as grace and deferment periods, and other deferrals.

Unsubsidized Student Loan Interest

As soon as the loan is disbursed, interest begins to accrue on all unsubsidized federal direct loans, as well as other student loans and parent loans (such as direct plus loans).

How Capitalization Happens?

When a student loan enters repayment, all accrued but unpaid interest is capitalized (added to the loan amount).

During repayment, the new loan amount is used to compute the monthly student loan payment due.

During the in-school and grace periods, interest on private student non-federal loans may be capitalized more frequently. Some loans capitalize interest every month.

Contact your lender or loan servicer to obtain information about how interest is capitalized on your private student loan.

For example, if the original loan balance is $30,000, the interest rate is 5%, and no payments are required during the 45-month in-school period and the 6-month grace period that follows, the amount of accrued interest when the repayment period begins is approximate:

$30,000 x (0.05 / 365 days) x 1,551 days = $6,373

So, in this scenario, the loan balance is $36,373 ($30,000 + $6,373) when you begin repaying your student loans. Your student loan debt has risen by $6,373 as a result of interest.

Interest Accrues Even During Periods of Non-Payment

While most federal student loans, don’t need to be paid while the borrower is enrolled full-time in school and during a grace period after graduation, certain private loans do.

Interest, on the other hand, begins accumulating for many loans as soon as the cash is released, even before you start paying.

If the student loan borrower is in deferment or forbearance, interest may still accrue.

You will continue to be charged interest under any sort of payment plan if you have an eligible loan in an income-driven repayment program.

Even If the borrower misses a payment or goes into default, interest will continue to be charged.

Forbearance and Deferment are The Only 2 Ways to Stop Making Payments

Deferment and forbearance are two methods to suspend making loan payments. Both imply that payments will be delayed for a specific length of time.

If the loan is in deferment or forbearance and the borrower isn’t making payments, interest continues to build up and is capitalized when repayment resumes.

Negative Amortization in Income-Driven Repayment plans

Negative amortization is permitted under all of the income-driven repayment plan choices available to borrowers.

When a borrower’s monthly student loan payment doesn’t enough to cover the cost of new interest accruing on the loan, it is said to have negative amortization.

  • Income-based repayment plan.
  • Income-contingent repayment plan.
  • Pay-as-you-earn repayment plan.
  • Revised-pay-as-you-earn repayment plan.

All allow this situation to occur.

If a payment plan is badly amortized, the monthly payment may be less than the new interest that has accrued since your last payment.

If you do not make any changes, your loan will increase as you pay down your debt, even if it is fully repaid.

How Do Principal and Interest Payments Affect the Amount of Your Loan?

The monthly payments are paid first out of any late charges or collection costs, followed by the remaining amount owing after all of that is taken care of.

Monthly student loan payments include both interest and principal, just as most debt.

The amount of interest owing decreases as the loan balance drops with each repayment.

The principal balance drops more quickly with each successive payment, at least if your monthly payment is greater than the interest charged each month when monthly payments are consistent or a set amount every month.

A student loan borrower’s payment is applied to the principal balance first and then to the interest when they submit it to their lender. 

If a borrower exceeds the monthly payment, it is often applied to the principal amount, resulting in the loan balance declining faster and faster each month.

Extra payments will result in the loan being paid off early, resulting in a shorter life for the loan and the total amount of interest paid.

Let’s assume a borrower has a $30,000 loan at the start of repayment with an interest rate of 5% and a 10-year level repay schedule.

They would pay $318.21 each month and accrue $8,183.1 in total interest over the loan’s term.

For the first month, the payment would be applied as follows:

$125 to interest ($30,000 x 0.05 / 12)

$193.21 to the principal ($318.21 – $125)

How to Reduce the Interest Paid on your Student Loans

1. Pay your Student Loan Debt on a Shorter Repayment Schedule

Some private lenders allow you to determine how long you want to pay back your student loan, while others limit you to a specific period.

If you pick a shorter payment period, you will save money in the long run, but you will have to pay interest monthly.

2. Refinance your Student Loan Debt (If you Found Better Terms)

Refinancing may save you money in the long run.

If your credit score has improved since you took out your loans, this is extremely beneficial.

Students’ credit scores improve as they complete school and get jobs, often leading to a better score than when they were 18 or 19 years old.

Borrowers with higher credit scores may refinance their loans to a lower monthly payment since they fulfill the criteria for reduced interest rates.

Because of changes in interest rates, rules, and laws implemented by the federal government over time, as well as a variety of other reasons, It’s difficult to predict your total cost.

3. Use Automatic Payments

In most cases, lenders will allow you to set up automatic payments in exchange for a student loan interest rate reduction of 0.25%, although this varies by lender and is subject to change.

This is frequently the case. By getting rid of the need for monthly payments, you may save money on your loan – or be concerned about not making one.

4. Make Additional Payments

Reduce your student loan faster and further by making bigger principal payments while in repayment.

If you do this, the principal amount will be paid off sooner than expected in your strategy, resulting in lower interest expenses over time.

You may make recurring monthly payments or make a one-time lump sum payment, such as after receiving graduation presents.

5. Pay your Student Loan While You’re In the School

If you can’t make any payments, deferring them or providing grace periods where you are not required to make payments while you are in school is a wonderful alternative.

You’ll be saving money by deferring payments. Even if you put off your payments, your loan will continue to accrue interest and you’ll have to pay it later.

When you add up interest and other costs, the overall cost when the deferment expires is much greater.

Even if you just have enough money to pay $25 monthly, you might be able to decrease your debt.
