Which method for calculating a credit card balance takes into account both the purchase and the payment made during the payments made during the billing cycle

The Adjusted Balance Method

Explanation:

The Adjusted Balance method calculates finance charges on monies owed at the end of the billing cycle after all transactions, including debits and credits have been posted to the account which include both the purchase and the payment made during the billing cycle.

It usually results in lower finance costs for the consumer because interest is calculated on the final amount instead of day to day.
