Upstart auto loans

Caribou auto loans

How to choose between Upstart and Caribou

Caribou is the obvious choice if you want to include a co-borrower, but you may want to opt for Upstart anyway if you only need to refinance a small amount.

APR range

Caribou boasts a slightly lower minimum and maximum APR than Upstart. Rates fall between 5.48 and 28.55 percent versus 6.89 and 29.99 percent for Caribou and Upstart, respectively. However, keep in mind that the lowest rate advertised is not always the one that you are offered.

Minimum credit score

Upstart is especially good if you have little remaining on your current car loan or if you have bad credit. The lenders in its network accept scores as low as 510. So, while you can’t apply with a cosigner like with Caribou, you may not need one to qualify.

Caribou, on the other hand, has a credit score minimum of 640, which falls in the fair credit range. However, the option to add cosigners may increase your odds of approval. It may also be able to help you lower your interest rate more than Upstart.

Loan amount

If you have a large amount left on your auto loan, Caribou is the better option since you can refinance up to $125,000. By comparison, Upstart may be better suited for borrowers looking to refinance smaller loan amounts from $3,000.

Fees

Both Upstart and Caribou work with lenders that may charge origination fees. However, Upstart’s maximum origination fee is almost $500 higher than Caribou’s.

While it is a hefty processing fee, both lenders are fully upfront about the steep price tag. Other lenders charging a similar fee may not disclose it so clearly before you apply. Most importantly, you may not be charged for it at all. Check to see if it will be added to your bill before signing.

The bottom line: Which lender is better?

Both Upstart and Caribou offer different opportunities and benefits for drivers looking to refinance their auto loan. Upstart is a solid choice for borrowers who want to prioritize qualifying independently for a refinance, while Caribou offers a customer focus that hesitant borrowers may especially appreciate.

And if you are matched with a lender through Upstart or Caribou, double-check that it has good ratings and meets your needs. You are never obligated to apply with a lender just because you are matched, and you may be able to find better rates elsewhere.

Compare more lenders before applying

Before you refinance an auto loan with Upstart or Caribou, get quotes from at least three to five other lenders to compare rates and repayment terms. That way, you can increase your chances of getting the best deal for your financial situation.
