Calculating the monthly interest cost on a student loan is relatively simple. To start, divide the loan’s annual interest rate by the number of days in a year (i.e., 365), then multiply the resulting daily interest rate by the loan balance. Finally, multiply the resulting daily interest💞 cost by the number of days in your billing cycle (e.g., 30).
Key Takeaways
- Student loan interest can be calculated in three simple steps: Divide the interest rate by 365, multiply by the loan balance, and multiply by the number of days in the billing cycle.
- While most student loans charge simple interest, some private student loans charge compound interest, leading to higher total interest costs.
- You can pay less in student loan interest by repaying the debt early and, in some cases, strategically refinancing the loan.
Calculatiꦰng Your Monthly Student Loan Interest: Step-by-Step
Let’s break൩ down how to calculate your monthly student loan interest with an example. Suppose you have a $30,000 student loan at a 6% annual interest rate.
- Step 1: Divide the annual interest rate by the number of days in the year to get the daily interest rate. In this case, that would be 0.06 / 365 = 0.000164 (0.0164%).
- Step 2: Figure out your daily interest charge by multiplying the daily interest rate by your student loan balance. In this case, that’s 0.000164 x $30,000 = $4.92.
- Step 3: Convert the daily interest charge into a monthly amount by multiplying it by the number of days in your billing cycle. Assuming our example uses a 30-day billing cycle, that would mean $4.92 x 30 = $147.6. In other words, you’d pay $147.60 in interest for the month.
Most student loans begin accruing interest as soon as loan funds are 澳洲幸运5官方开奖结果体彩网:disbursed—even if you aren’t required to make payments right away. For example, you may not need to pay while you’re in school or if your loans are in 澳洲幸运5官方开奖结果体彩网:deferment or 澳洲幸运5官方开奖结果体彩网:forbearance. Regardless, the unpaid interest will accumulate and may even be 澳洲幸运5官方开奖结果体彩网:capitalized, which means it’d be added to the 澳洲幸运5官方开奖结果体彩网:principal balance.
However, if you get a subsidized loan, the federal government will cover the interest while you’re in school and for a six-month 澳洲幸运5官方开奖结果体彩网:grace period afterward, in addition to during any deferment periods.
Interest Rates: Simple vs. Compound
So far, we’ve calculated student loan interest based on the principal loan amount. This assumed that the loan charged 澳洲幸运5官方开奖结果体彩网:simple interest, as this is what’s used for federal student loans. That said, there’s also 澳洲幸运5官方开奖结果体彩网:compound interest, or interest that’s based on the loan principal and an♒y accru♏ed interest, which some private lenders may charge. Over time, the interest compounds because it’s based on an ever-growing principal amount.
To illustrate, let’s assume our $30,000 student loan in the prior example has a compound interest rate. As such, the daily interest rate on the second day would be applied to $30,004.92 (the principa𒁃l p🥃lus the previously accrued interest) instead of the original $30,000.
Tip
Before taking out a private student loan, check to see whether it charges 澳洲幸运5官方开奖结果体彩网:simple or compound interest, as this♍ can have a big impact on your total loan costs.
Interest Rates: Fixed vs. Variable
Private student loans also may have variable rates that change alongside the underlying benchmarks tied𒉰 to them. In this case, you’d ne🍎ed to confirm your loan’s current rate before calculating the monthly interest cost.
Warning
A variable interest rate on a student loan could mean a lower initial rate. However, you 🐲also run the risk of rates rising, which could i💟ncrease your total interest costs.
How Student Loan Amortization Works
Most student loans are amortized over 10 years with fixed monthly payments. Typically, the portion of each pay𝔍ment that goes toward paying down interest is highest at the start of the loan and then gradually lowers as the loan balance decreases.
Tip
To learn how much of your monthly payment goes toward principal vs. interest, request an amortization schedule from your lender or plug your loan details into a 澳洲幸运5官方开奖结果体彩网:loan calculator.
That said, the United States Department of Education has several income-driven repayment (IDR) plans available that base your monthly payment on your income and family size, which can result in a lower monthly payment. Any debt that remains at the end of the repayment period may be🅰 forgiven.
Having a lower monthly payment under an IDR plan can result in negative amortization, or when a loan payment fails to fully cover the interest charges, which causes the principal balance to increase. Under certain plans and circumstances, the government will pay for at least a portion of the uncovered interest.
Important
The future of the current IDR plans is up in the air following a federal court injunction stopping the Department of Education from implementing the Saving on a Valuable Education (SAVE) plan and parts of other plans.
Tips for Paying Less Interest on Student Loans
The easiest way to pay less interest on your student loan is to pay down the principal early. This could involve adding a little ಌextra to each monthly payment or putting a large windfall like a tax refund toward paying down the loan. Either way, this will lower your total interest costs.
Alternatively, you may want to consider refinancing your student loan. For example, if interest rates fall below what they were when you originally took out the loan, a refinance could allow you to lock in a cheaꦯper rate. ওHowever, refinancing from a federal student loan to a private one will cost you the former’s benefits and protections.
The Bottom Line
Knowing how to calculate student loan interest is an important skill. It helps you compare offers and determine whether a loan suits your financial needs💦. Of course, compound interest and variable rates can complicate the calculation, so be sure to read the loan terms carefully.
