The Average Daily Balance (ADB) method is commonly used by credit card companies to calculate interest charges based on the amount owed each day. This approach provides a fairer way to determine interest charges compared to the previous end-of-month balance method, as it accounts for how the balance changes throughout the billing period.
Historical Background
The concept of the Average Daily Balance has been developed as part of financial institutions' efforts to more accurately reflect the borrowing and repayment behavior of their customers over the billing cycle, rather than applying interest to a snapshot figure at the end of the month.
Calculation Formula
The formula for calculating the Average Daily Balance (ADB) is relatively simple:
\[ ADB = \frac{SDB}{D} \]
where:
- \(ADB\) is the Average Daily Balance ($/day),
- \(SDB\) is the sum of daily balances ($),
- \(D\) is the number of days in the period.
Example Calculation
If the sum of daily balances over a 30-day period is $15,000, the Average Daily Balance is calculated as:
\[ ADB = \frac{15000}{30} = 500 \]
This means the Average Daily Balance is $500/day.
Importance and Usage Scenarios
Understanding and calculating the Average Daily Balance is essential for anyone using credit products. It helps in estimating monthly interest charges and encourages better financial management, such as making payments earlier in the billing cycle to reduce the ADB and, consequently, the interest charges.
