When you borrow for school, you end up paying back more money than the actual amount initially borrowed. Why? Because lenders charge interest when you borrow money. The higher the interest rate, the more you’ll have to pay — and the more difficult student loan repayment becomes.

Comparison shopping to find loans offering the best student loan interest rates is important. We’ll help you get started with some key information about how student loan interest works.

We’ll also help you figure out the federal student loan interest rate and private student loan rates so that you’ll have a better idea of what you may need to pay when you borrow for school.

Understanding the federal student loan interest rate

The federal student loan interest rate is set by the government. The rates are standardized — meaning that everyone who is eligible pays the same interest rate — but they can change from year to year. In fact, rates went up in 2018, so students borrowing for the 2018-19 academic year will pay more than those who borrowed last year.

Rates have gone up and down on federal student loans, so it’s important to know the interest charge before borrowing. This table shows how interest rates have fluctuated over the past five years for different types of federal student loans.

Type of Loan Direct Subsidized Loans Direct Unsubsidized Loans for Undergrads Direct Unsubsidized Loans for Grad Students Direct PLUS Loans
Who’s the loan for? Undergrads with demonstrated financial need Undergrads regardless of need Grad students regardless of need Grad students or parents of dependent undergrads
Interest rates for 2014-15 4.66% 4.66% 6.21% 7.21%
Interest rates for 2015-16 4.29% 4.29% 5.84% 6.84%
Interest rates for 2016-17 3.76% 3.76% 5.31% 6.31%
Interest rates for 2017-18 4.45% 4.45% 6.00% 7.00%
Interest rates for 2018-19 5.05% 5.05% 6.60% 7.60%
Note: New rates take effect July 1 of each year.

Those interest rates can cause your loans to balloon. For example, if you had the average student loan balance of $39,400 with a 5.05% interest rate and a $419 monthly payment, you’d pay over $10,000 in interest fees over 10 years. In total, you’d pay back more than $50,000.

But there are ways to save money on interest, including refinancing student loans to a lower rate or paying off your loans more quickly.

Once you fully understand how student loan interest rates work, you can create a plan that works for your finances and helps you pay less interest over time.

Understanding private student loan rates

While federal student loan rates are standardized by the government, there is much more variation in private student loan rates since lenders can decide how much interest to charge borrowers.

It’s important to shop around among private student loan providers to compare interest charges and find the best student loan rates. As of Sept. 19, 2018, rates from top lenders vary between 3.69% and 12.99%, but rates fluctuate and your credit score and other factors affect the interest you’ll pay.

At first glance, these private student loans might seem tempting since they can start at lower interest rates than federal ones. But it’s harder to qualify for these low rates, and these loans might carry more risk than federal student loans.

That’s because federal student loans come with protections such as access to income-driven repayment (IDR) plans, forbearance and deferment, and even student loan forgiveness options. With private loans, you don’t have access to perks such as IDR plans or forgiveness.

But private student loans can be a useful tool. If you exhaust all your federal student loan options and still need more money to complete your degree, private loans can help fill the gap so that you can finish school.

Your loan term affects the amount of student loan interest you pay

Your interest rate is one of the major factors determining how much you pay back on your federal or private student loans. But the length of time you take to repay your loan also makes a big impact.

While repaying your loan over a longer time allows you to have lower monthly payments, this approach means you’ll pay much more in interest. You can use our student loan term comparison calculator to see how loan terms affect the total amount you’d pay. We’ve done this for you below with a $28,000 loan at 5% interest to showcase how much repayment periods matter.

As you can see, the longer you hold the loan, the more it’ll cost. Although the five-year plan comes with much higher monthly payments, following the 25-year plan will cost you $17,402 extra in the end.

How to reduce the student loan interest you pay

Because student loan interest charges can add so much to your educational costs, it’s a good idea to explore options to reduce your expenses. Following these steps can help you save money.

1. Before you borrow: Apply for scholarships and grants

One of the best things you can do is to apply for grants and scholarships. Unlike student loans, which you have to repay, scholarships and grants are free money that you don’t have to pay back. Plus, you can apply for and receive multiple grants and scholarships, lowering how much you need to borrow in student loans.

Devote an hour or two every week to finding grants and scholarships and applying. You can also meet with your college’s financial aid office to see if there are institutional aid programs for which you qualify.

2. Once you borrow: Try to boost your income to pay your loans down faster

Besides scholarships, launching a high-paying college side hustle can make a huge difference in reducing your reliance on student loans.

And if you’ve already graduated, you can also look into side hustle opportunities that you can do while working full time. If you apply all the extra income straight to your loans, you can really get ahead on repayment. Our extra payment calculator shows how much of an impact these extra payments make.

3. Once you’re stable: Refinance your student loans

Once you graduate, refinancing your student loans can be a great option for lowering your interest rates.

When you refinance your loans, you can take out a new loan with completely different repayment terms. You could qualify for a loan with a lower interest rate, different repayment period, and even a lower monthly payment.

Refinancing does have some drawbacks to keep in mind. For example, if you refinance federal loans, you’ll lose out on access to IDR plans and loan forgiveness. You also won’t get borrower protections such as the ability to defer loan payments.

But if you’re focused on become debt-free as quickly as possible, refinancing with a lower-interest loan can help you pay off your loan ahead of schedule.

Understanding how student loan interest works helps you make smart choices

For new and current borrowers alike, student loan interest rates can be extremely frustrating. After all, it’s bad enough to enter adulthood with tens of thousands of dollars in debt, much less to have to pay interest on it.

But now that you what factors determine the interest you pay, you can make smart choices for dealing with your debt.

2 Important Disclosures for Laurel Road.

Laurel Road Disclosures

APR stands for “Annual Percentage Rate.” Rates listed include a 0.25% EFT discount, for automatic payments made from a checking or savings account. Interest rates as of 11/8/2018. Rates subject to change.

Variable rate options consist of a range from 3.27% per year to 6.09% per year for a 5-year term, 4.64% per year to 6.14% per year for a 7-year term, 4.69% per year to 6.19% per year for a 10-year term, 4.94% per year to 6.44% per year for a 15-year term, or 5.19% per year to 6.69% per year for a 20-year term, with no origination fees. APR is subject to increase after consummation. The variable interest rate will change on the first day of every month (“Change Date”) if the Current Index changes. The variable interest rates are based on a Current Index, which is the 1-month London Interbank Offered Rate (LIBOR) (currency in US dollars), as published on The Wall Street Journal’s website. The variable interest rates and Annual Percentage Rate (APR) will increase or decrease when the 1-month LIBOR index changes. The variable interest rates are calculated by adding a margin ranging from 0.98% to 3.80% for the 5-year term loan, 2.35% to 3.85% for the 7-year term loan, 2.40% to 3.90% for the 10-year term loan, 2.65% to 4.15% for the 15-year term loan, and 2.90% to 4.40% for the 20-year term loan, respectively, to the 1-month LIBOR index published on the 25th day of each month immediately preceding each “Change Date,” as defined above, rounded to two decimal places, with no origination fees. If the 25th day of the month is not a business day or is a US federal holiday, the reference date will be the most recent date preceding the 25th day of the month that is a business day. The monthly payment for a sample $10,000 loan at a range of 3.27% per year to 6.09% per year for a 5-year term would be from $180.89 to $193.75. The monthly payment for a sample $10,000 loan at a range of 4.64% per year to 6.14% per year for a 7-year term would be from $139.65 to $146.76. The monthly payment for a sample $10,000 loan at a range of 4.69% per year to 6.19% per year for a 10-year term would be from $104.56 to $111.98. The monthly payment for a sample $10,000 loan at a range of 4.94% per year to 6.44% per year for a 15-year term would be from $78.77 to $86.78. The monthly payment for a sample $10,000 loan at a range of 5.19% per year to 6.69% per year for a 20-year term would be from $67.05 to $75.68.

However, if the borrower chooses to make monthly payments automatically by electronic funds transfer (EFT) from a bank account, the variable rate will decrease by 0.25%, and will increase back up to the regular variable interest rate described in the preceding paragraph if the borrower stops making (or we stop accepting) monthly payments automatically by EFT from the designated borrower’s bank account.

  1. Student loan Refinance:
    Fixed rates from 3.899% APR to 7.979% APR (with AutoPay). Variable rates from 2.470% APR to 6.990% APR (with AutoPay). Interest rates on variable rate loans are capped at either 8.95% or 9.95% depending on term of loan. See APR examples and terms. Lowest variable rate of 2.470% APR assumes current 1 month LIBOR rate of 2.30% plus 0.91% margin minus 0.25% ACH discount. Not all borrowers receive the lowest rate. If approved for a loan, the fixed or variable interest rate offered will depend on your creditworthiness, and the term of the loan and other factors, and will be within the ranges of rates listed above. For the SoFi variable rate loan, the 1-month LIBOR index will adjust monthly and the loan payment will be re-amortized and may change monthly. APRs for variable rate loans may increase after origination if the LIBOR index increases. The SoFi 0.25% AutoPay interest rate reduction requires you to agree to make monthly principal and interest payments by an automatic monthly deduction from a savings or checking account. The benefit will discontinue and be lost for periods in which you do not pay by automatic deduction from a savings or checking account. *To check the rates and terms you qualify for, SoFi conducts a soft credit inquiry. Unlike hard credit inquiries, soft credit inquiries (or soft credit pulls) do not impact your credit score. Soft credit inquiries allow SoFi to show you what rates and terms SoFi can offer you up front. After seeing your rates, if you choose a product and continue your application, we will request your full credit report from one or more consumer reporting agencies, which is considered a hard credit inquiry. Hard credit inquiries (or hard credit pulls) are required for SoFi to be able to issue you a loan. In addition to requiring your explicit permission, these credit pulls may impact your credit score.

To qualify, a borrower must be a U.S. citizen or permanent resident in an eligible state and meet SoFi’s underwriting requirements. Not all borrowers receive the lowest rate. To qualify for the lowest rate, you must have a responsible financial history and meet other conditions.

Rates and Terms are subject to change at anytime without notice and are subject to state restrictions. SoFi refinance loans are private loans and do not have the same repayment options that the federal loan program offers such as Income Based Repayment or Income Contingent Repayment or PAYE.

Variable interest rates range from 2.79%-8.39% (2.79%-8.39% APR) and will fluctuate over the term of the borrower’s loan with changes in the LIBOR rate, and will vary based on applicable terms, level of degree earned and presence of a cosigner.

The borrower will be presented with an Application Disclosure and an Approval Disclosure within the application process before they accept the terms and conditions of their loan.
  2. Federal Loan vs. Private Loan Benefits: Some federal student loans include unique benefits that the borrower may not receive with a private student loan, some of which we do not offer with the Education Refinance Loan. Borrowers should carefully review their current benefits, especially if they work in public service, are in the military, are currently on or considering income based repayment options or are concerned about a steady source of future income and would want to lower their payments at some time in the future. When the borrower refinances, they waive any current and potential future benefits of their federal loans and replace those with the benefits of the Education Refinance Loan. For more information about federal student loan benefits and federal loan consolidation, visit http://studentaid.ed.gov/. We also have several resources available to help the borrower make a decision at http://www.citizensbank.com/EdRefinance, including Should I Refinance My Student Loans? and our FAQs. Should I Refinance My Student Loans? includes a comparison of federal and private student loan benefits that we encourage the borrower to review.
  3. Citizens Bank Education Refinance Loan Eligibility: Eligible applicants may not be currently enrolled. Applicants with an Associate’s degree or with no degree must have made at least 12 qualifying payments after leaving school. Qualifying payments are the most recent on time and consecutive payments of principal and interest on the loans being refinanced. Primary borrowers must be a U.S. citizen, permanent resident or resident alien with a valid U.S. Social Security Number residing in the United States. Resident aliens must apply with a cosigner who is a U.S. citizen or permanent resident. The cosigner (if applicable) must be a U.S. citizen or permanent resident with a valid U.S. Social Security Number residing in the United States. For applicants who have not attained the age of majority in their state of residence, a cosigner will be required. Citizens Bank reserves the right to modify eligibility criteria at anytime.

Education Refinance Loans are subject to credit qualification, completion of a loan application/consumer credit agreement, verification of application information, certification of borrower’s student loan amount(s) and highest degree earned.
  4. Loyalty Discount Disclosure: The borrower will be eligible for a 0.25 percentage point interest rate reduction on their loan if the borrower or their co-signer (if applicable) has a qualifying account in existence with us at the time the borrower and their co-signer (if applicable) have submitted a completed application authorizing us to review their credit request for the loan. The following are qualifying accounts: any checking account, savings account, money market account, certificate of deposit, automobile loan, home equity loan, home equity line of credit, mortgage, credit card account, or other student loans owned by Citizens Bank, N.A. Please note, our checking and savings account options are only available in the following states: CT, DE, MA, MI, NH, NJ, NY, OH, PA, RI, and VT and some products may have an associated cost. This discount will be reflected in the interest rate disclosed in the Loan Approval Disclosure that will be provided to the borrower once the loan is approved. Limit of one Loyalty Discount per loan and discount will not be applied to prior loans. The Loyalty Discount will remain in effect for the life of the loan.
  5. Automatic Payment Discount Disclosure: Borrowers will be eligible to receive a 0.25 percentage point interest rate reduction on their student loans owned by Citizens Bank, N.A. during such time as payments are required to be made and our loan servicer is authorized to automatically deduct payments each month from any bank account the borrower designates. Discount is not available when payments are not due, such as during forbearance. If our loan servicer is unable to successfully withdraw the automatic deductions from the designated account three or more times within any 12-month period, the borrower will no longer be eligible for this discount.
  6. Co-signer Release: Borrowers may apply for co-signer release after making 36 consecutive on-time payments of principal and interest. For the purpose of the application for co-signer release, on-time payments are defined as payments received within 15 days of the due date. Interest only payments do not qualify. The borrower must meet certain credit and eligibility guidelines when applying for the co-signer release. Borrowers must complete an application for release and provide income verification documents as part of the review. Borrowers who use deferment or forbearance will need to make 36 consecutive on-time payments after reentering repayment to qualify for release. The borrower applying for co-signer release must be a U.S. citizen or permanent resident. If an application for co-signer release is denied, the borrower may not reapply for co-signer release until at least one year from the date the application for co-signer release was received. Terms and conditions apply.
