How do you calculate average daily balance?

AnswerTake the account balance at the end of each day's business. Add all of these balances and divide by the number of days.

Average Daily Balance is the practice of crediting an account from the day a payment is received or debiting an account on the day a charge is made. It is a daily tracking of what is owed. The lender adds the beginning balance for each day in the billing period to the charges made that day, and then subtracts any payments and/or credits made to the account that day. Adjusted Balance adds charges and subtracts payments made during the billing cycle from the balance at the end of the previous billing cycle. This method is more advantageous to borrowers and credit card holders.
