1. What is Average Daily Balance?

The Average Daily Balance (ADB) is a method used by credit card companies to calculate interest charges. It represents the sum of each day's balance divided by the number of days in the billing period.

2. How Does the Calculator Work?

The calculator uses the ADB formula:

Where:

• \(\sum \text{(daily balances)}\) — Sum of all daily balances during the period
• \(\text{days}\) — Number of days in the billing period

Explanation: The calculation involves adding up the balance from each day in the billing cycle and dividing by the total number of days.

3. Importance of ADB Calculation

Details: Average Daily Balance is crucial for determining credit card interest charges, understanding finance charges, and managing personal finances effectively.

4. Using the Calculator

Tips: Enter daily balances separated by commas (e.g., "100, 150, 200") and the number of days. All values must be valid positive numbers.
