How Do You Calculate The Interest Charge?
We use a method called Average Daily Balance (including new transactions). Under this method, we first calculate your daily balance; for each Credit Plan, we 1) take the beginning balance and add in new transactions and the periodic interest charge on the previous day’s balance, then 2) subtract any payments and credits for that Credit Plan as of that day. The result is the daily balance for each Credit Plan. However, if you paid your previous month’s non-promotional purchases balance in full (or if your balance was zero or a credit amount), new transactions which post to your purchase or special purchase Credit Plans are not added to the daily balances. Also, transactions subject to a grace period are not added to the daily balances.
Next, to find your Average Daily Balance we: 1) add the daily balances together for each Credit Plan, and 2) divide the sum by the number of days in the billing cycle.
At the end of each billing cycle, we determine your interest charge as follows: 1) multiply your Average Daily Balance by the daily periodic rate (APR divided by 365) for each Credit Plan and 2) multiply the result by the number of days in the billing period. We add the interest charges for all Credit Plans together. The result is your total interest charge for the billing cycle.
NOTE: Due to rounding or a minimum interest charge, this calculation may vary from the interest charge actually assessed.
