Your payments are due on the first of the month and are considered late if not received by the 14th. A late fee is applied on the 15th for any account that has not paid in full. The first time an account becomes late, the fee is $50. If the account remains past due and a further late fee is applied the following month, that fee is $100, and it stays at $100 for each additional month the balance remains past due. Once the balance is brought current, the fee returns to $50 the next time an account becomes late.
