CareCredit and LendingClub don’t have long-term effects on your credit. In fact, these third-party financing companies can even boost your credit score if you make your payments on time. While there may be a slight dip at first, this is due to the fact that a credit check will be run to learn which type of payment plan you qualify for. As long as you make timely payments, CareCredit and LendingClub won’t hurt your credit score.
