If the credit card statement begins on the 1st of October and ends on the 30th October and I purchased $1000 worth of goods, the closing balance on the statement says $1000 and is due by the 25th of November. If I purchased another item at $500 on the 12th of November the credit card has $1500 outstanding, if I payed the closing balance of $1000 on let's say the 23rd of November, is the other $500 interest free until the 25th of December in the November statement?
