<prompt> Human: Hi PF, Ive got a question about how to pay my CC bill to avoid accruing interest.So first of all, Ive never had a CC before as Ive never needed one. I got my first card in the beginning of August purely to build credit. My plan is to use it for online purchases and pay it off in full every month to avoid accruing interest.Since the beginning of August Ive made several hundred dollars of purchases. I just got my first billing statement with a minimum payment of 25 due in mid September.When should I pay the balance to avoid interest? If I pay now and then make new purchases before the due date, will I pay interest on the new purchases? Do I have to have zero balance on the due date?EDIT: Thanks guys, I got it figured out now!  <response>: Pay the entire Statement Balance on or before the due date. That is the huge secret to never having to pay interest on a CC.If you always pay the Statement Balance then you wont be charged interest. If you ever carry anything over pay less than the statement balance by the due date then you will be charged interest for the overage plus all new purchases until you hit a total balance of 0. This is a dangerous path to go down, so pay the entire Statement Balance by the due date.
