<prompt> Human: I have heard that if you dont pay off your credit card in full every month, then you are charged interest on the MAXIMUM balance your card held that month, not the ending balance. Is this true? If so, would spending money between the payment due date usually around the 27th for me and the statement balance date usually around the 4th cause me to be charged with this extra interest even though my balance was paid in full on the due date?What if I pay off my card in full before the due date and then charge more between the payment and the due date? Would I have to make another payment on the due date? I know these questions are stupid and should be basic knowledge, but I cannot find these answers. I have thus far avoided paying interest by paying the exact amount on the due date and then not using the card again until after the statement has posted the following week, but Im almost sure this is unnecessary. Please help.  <response>: To avoid paying interest, pay the statement balance in full, on or before the due date. This is as simple as it gets.Charges that appear after statement cutoff do not accrue interests if you dont already pay interests.
