Introduction
Credit card interest calculations can be complex and confusing, especially when different methods are used to determine the interest charged. In this article, we will explore the average daily balance method, a common approach used by credit card companies to calculate interest. We will use a case study of Sergei, a credit card holder, to illustrate how this method works and how it affects his credit card balance.
The Average Daily Balance Method
The average daily balance method is a way of calculating credit card interest by averaging the daily balance of the account over a billing cycle. This method takes into account the balance of the account at the beginning and end of the billing cycle, as well as any transactions that occur during the cycle. The average daily balance is then used to calculate the interest charged on the account.
Sergei's Credit Card Balance
Sergei has a credit card that uses the average daily balance method. For the first 12 days of one of his billing cycles, his balance was . For the last 18 days of the billing cycle, his balance was . We will use this information to calculate the average daily balance and determine the interest charged on Sergei's credit card.
Calculating the Average Daily Balance
To calculate the average daily balance, we need to first determine the total balance for the billing cycle. This can be done by adding the balance for the first 12 days to the balance for the last 18 days.
# Define the balances for the first 12 days and the last 18 days
balance_first_12_days = 350
balance_last_18_days = 520
# Calculate the total balance for the billing cycle
total_balance = balance_first_12_days + balance_last_18_days
Next, we need to calculate the number of days in the billing cycle. Since Sergei's balance was for the first 12 days and for the last 18 days, the total number of days in the billing cycle is 30.
# Define the number of days for the first 12 days and the last 18 days
days_first_12_days = 12
days_last_18_days = 18
# Calculate the total number of days in the billing cycle
total_days = days_first_12_days + days_last_18_days
Now that we have the total balance and the total number of days, we can calculate the average daily balance.
# Calculate the average daily balance
average_daily_balance = total_balance / total_days
Calculating the Interest Charged
Once we have the average daily balance, we can calculate the interest charged on Sergei's credit card. The interest rate is typically expressed as a decimal, so we will assume an interest rate of 18% per annum.
# Define the interest rate
interest_rate = 0.18
# Calculate the interest charged
interest_charged = average_daily_balance * interest_rate
Conclusion
In this article, we used a case study of Sergei's credit card to illustrate how the average daily balance method works. We calculated the average daily balance and determined the interest charged on Sergei's credit card. This method is commonly used by credit card companies to calculate interest, and understanding how it works can help consumers make informed decisions about their credit card usage.
