Credit Card Balance Computation Method

Balance Computation Method

The balance computation method is used to determine how interest on your account is calculated. There are a variety of methods. The most common method used is the Average Daily Balance.


To calculate this:


Balance x APR x # of days in the billing cycle

# of days in the calendar year
