What is a Good Interest Rate?

Interest rates will vary significantly based on the lender and type of loan. So, there really isn’t a specific threshold of what is considered a “good” interest rate. Generally speaking, however, an interest rate at or above 10% is considered very high, while interest rates less than 7% are on the lower end.

Across all student loans, 5.8% is the average interest rate. Use the average interest rate as a marker when determining if the interest rate offered to you is good.

Rates Are Just One Piece of the Puzzle

While the interest rate on your student loan is an incredibly important factor, it is only one piece of a much more complex puzzle. When selecting a student loan, you should also consider factors such as whether the interest rate is fixed or variable, the repayment period, and the projected monthly payment.

Fixed vs Variable Interest Rate

A fixed interest rate will remain the same throughout the life of the loan, while a variable interest rate is subject to change due to market conditions. So, if you borrowed a loan with a 5% fixed interest rate, it would remain at a 5% interest rate up until the day you pay it off. On the other hand, if you borrowed a loan with a variable interest rate starting at 5%, the rate could fluctuate up and down throughout the life of the loan.

There are pros and cons to both fixed and variable rate loans. Select the option you feel most comfortable with.

Repayment Period

Generally speaking, the longer the repayment period, the more you will pay over the life of the loan. Consider the repayment periods offered to you and how they will impact what you pay throughout repayment.

Principal Balance$30,000$30,000
Interest Rate5%5%
Repayment Period10 years15 years
Monthly Payment$318$237
Total Paid$38,184$42,703

With a shorter repayment period, you will have larger monthly payments. However, if you’re able to afford them, a shorter repayment period can save you quite a bit over the life of the loan.

Projected Monthly Payment

During repayment, you will be required to make at least the minimum monthly payment on your loan. As illustrated by the table above, the monthly payment will change based on the repayment period and interest rate you have.

Some private student lenders may only offer one or two repayment periods. Before agreeing to a student loan, consider the projected monthly payment amount. If the amount does not seem feasible for you given your projected monthly income after graduation, you may want to explore other student loan options.
