How to choose between RateGenius and Upstart

RateGenius and Upstart both offer access to a network of lenders. The better choice for you will depend on your credit profile, whether you want to add a co-signer and how much of a hurry you’re in.

Choose RateGenius if you are focused on a fast refinance or need a bigger loan with a co-borrower

Many borrowers explore refinancing when they need new loan terms as soon as possible. If this is the case, RateGenius is an excellent option. It beats Upstart by promising funding in just 24 to 48 hours if you’re approved.

RateGenius also has benefits to offer borrowers in less-urgent financial situations. With excellent credit, borrowers may score an interest rate as low as 4.67 percent. This is below the industry average of 7.43 percent for used-car buyers with excellent credit in 2023’s third quarter. (Refinance rates tend to be similar to used car rates.)

Choose Upstart if you need flexible credit qualifications

Upstart is a fitting choice for borrowers who do not have a lengthy credit history or may have a damaged score. Unlike most traditional lenders, Upstart considers your employment and education history to determine your eligibility.

On top of that, Upstart accepts borrowers with bad credit scores as low as 510. That makes it a possible option if you have a limited credit history or bad credit. The lender also offers prequalification, which can give you an idea of your expected terms before you apply.

However, it’s important to note that Upstart’s lender network is less than half the size of RateGenius’ network. Your automated comparison shopping will draw from a much smaller pool.

Compare more lenders before applying

Both RateGenius and Upstart are worth a look to refinance and save some cash. However, both companies have fairly high minimum loan amounts to qualify. If you have an outstanding balance of less than $9,000, compare refinance rates from other lenders.
