Credit Card Balance Transfer Methodology

Credit card interest kicks in on the remainder of your unpaid balance each month. In the case of a balance transfer credit card, you are not charged any interest for some promotional period of time, after paying a transfer fee. For the above calculator, we assumed you begin with a set balance, added the cost of the transfer fee, and then began applying your fixed payment month after month. After the end of the promotional 0% APR period, the interest for each billing cycle is equal to the periodic rate multiplied by your balance after payment.

The periodic rate varies month to month, depending on the number of days in a billing period. In order to approximate this, we divide the card APR by 12, to get a monthly periodic rate.

The interest rate is then added to the balance after payment, and carries over into the next month where the process is repeated.
