Private student loans offer undergraduate and graduate students a wide range of funding options to help complete their education. While federal loans are easier to qualify for, they often offer less funding than private loans, leaving students hanging as they try to complete their education.

We reviewed nearly two dozen private student loan companies based on interest rates, repayment terms, deferment options, qualification requirements, and more. Here are our top seven choices.

A property of Goal Solutions, Inc. and Richland State Bank, Ascent is one of the few lenders to offer non-co-signer loans for undergraduates. This, combined with graduated repayment and flexible postponement options and rewards, makes it our choice as the best overall.    

Ascent offers two types of student loans for undergraduates with either a fixed or variable annual percentage rate (APR) and repayment terms of five, seven, 10, 12, or 15 years. Its co-signed loans come with a fixed APR starting at 3.22% and three repayment options: a deferred plan which gives you up to nine months after leaving school to begin repayments and a $25 flat-fee or interest-only repayments while in school.

Ascent’s non-co-signed undergraduate loans include a credit-based option with a fixed APR starting at 8.64% and an annual loan limit of $200,000 or a future income-based option as low as 14.96% with an annual loan limit of $20,000 (as of July 2022). Flat-fee and in-school interest-only payments are not available for non-co-signed undergraduate loans.

In addition to a 0.25% automatic payment discount (2.00% on co-signed credit-based student loans), Ascent also offers a 1% cash-back graduation reward subject to certain terms and conditions.

Earnest also offers a 0.25% autopay discount, and charges no origination, disbursement, prepayment, or late payment fees. In addition, borrowers can skip one payment every 12 months, although interest will still accrue and it will extend your payoff date. Students are required to be enrolled full-time and if applying without a co-signer, must have an annual income of at least $35,000, and a 650 credit score.     

Earnest provides borrowers with flexible forbearance options allowing them to postpone payments in three-month increments for up to 12 months total. These include deferments for unemployment, an involuntary decrease in income, and emergency and medical expenses.

Frequently Asked Questions 

What Is a Student Loan?

A student loan allows undergraduate or graduate students to borrow money to pay for tuition and other school-related expenses.

Like any other loan, student loans come with an interest rate that will increase the overall amount owed over time. This can be either a fixed rate or a lower variable rate that fluctuates with the market. Student loans are typically paid off in five to 20 years, depending on the lender and type of loan  

What Is The Average Current Interest Rate For a Student Loan?

Student loans can vary widely in the interest rates they offer. Fixed-rate loans often have a higher rate, with the lenders reviewed here offering rates from 3.22% to 13.57% (as of June 2022). Variable loan rates offered by these same lenders ranged from 0.94% to 12.40% (as of June 2022). 

Note that these rates take into consideration the 0.25% discount most lenders offer to borrowers who set up automatic repayment plans.    

How Long Is the Repayment Period for a Student Loan?

Most of the lenders we reviewed offered repayment terms between five to 15 years with some going as high as 20 for medical or law graduate students. 

While most require full monthly payments based on the terms set by the loan, some also offer graduated payments that start low and increase over time or extended repayment options that allow you to pay less each month but extend your repayment term length.  

Do I Need a Co-signer for a Student Loan?

While some private student loan companies require you to have a co-signer, most do not. With that said, a co-signer can dramatically improve your chances of being approved. 

Non-co-signer loans often require borrowers to have a high credit score or a certain minimum annual income to qualify. Co-signers are not bound to the entire term and can be usually released from a student loan within one to two years.    

Should I Get a Private Student Loan?

For most students, federal student loans are a better option than private loans. Not only are they easier to qualify for since they’re not based on credit, but they also offer more repayment options and a forgiveness program.

With that said, federal student loans do have caps and a private loan can provide the initial funding higher-tuition students like doctors and lawyers need to complete their education. 

How We Chose the Best Private Loans For Students 

When reviewing student loan companies for this review, we looked for lenders that offered a variety of terms, repayment options, deferments, and competitive rates to reduce the debt load on borrowers.    

We also drilled down to find lenders that specialize in different features or needs, such as refinancing options, support for graduate students, or enticements for co-signers. Rates were also a huge factor in our reviews and we made sure to be as transparent as possible about the range available.
