1. What is Average Daily Balance?

The Average Daily Balance (ADB) is a method used by financial institutions to calculate interest charges or rewards on accounts. It represents the sum of daily balances divided by the number of days in the period.

2. How Does the Calculator Work?

The calculator uses the ADB formula:

Where:

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

Explanation: This calculation method provides a fair representation of your account activity over time, which is particularly important for interest calculations on credit cards and savings accounts.

3. Importance of ADB Calculation

Details: Accurate ADB calculation is crucial for determining interest charges on credit cards, calculating interest earnings on savings accounts, and understanding how daily balance fluctuations affect your overall financial position.

4. Using the Calculator

Tips: Enter all daily balances separated by commas or new lines, and the total number of days. Ensure all values are positive numbers representing dollar amounts without currency symbols.

5. Frequently Asked Questions (FAQ)

Q1: Why is ADB important for credit card users?
A: Most credit card companies use ADB to calculate finance charges. A lower ADB means less interest paid.

Q2: How does ADB differ from daily balance?
A: Daily balance is your balance on a specific day, while ADB is the average of all daily balances over a period.

Q3: What's a good ADB for credit cards?
A: For credit cards, a lower ADB is better as it reduces interest charges. For savings, a higher ADB earns more interest.

Q4: How often should I calculate my ADB?
A: Monthly calculations are most common, as this aligns with typical billing cycles.

Q5: Does ADB include pending transactions?
A: Typically, financial institutions use posted transactions only when calculating daily balances for ADB.
