What is the effect of using a two-cycle balance method for calculating credit balances?

Using a two-cycle balance method for calculating credit balances has a significant impact on how interest is applied to unpaid balances. This method takes into account the balance from the previous billing cycle as well as the current cycle, which means that if the balance is not paid in full by the due date, interest can accrue on both cycles.

In contrast to a traditional single-cycle balance calculation, the two-cycle method effectively reduces the interest-free period for cardholders, as it requires them to pay off their balance in full to avoid accruing interest on the previous cycle's balance. Therefore, if a payment is not made in full, it eliminates the opportunity to maintain interest-free payments across billing cycles, leading to potential interest charges on accumulated balances. This method emphasizes the importance of paying full balances to avoid interest and encourages responsible credit use.
