To estimate your monthly payments, you can use the CareCredit Payment Calculator.
To avoid paying interest on purchases of $200 or more, simply make your minimum monthly payment and pay your full amount due by the end of the promotional period. Interest will be charged to your account from the purchase date if the promotional balance, including optional charges, is not paid in full within 6, 12, 18 or 24 months. Minimum monthly payments are required.
