1. What is Credit Card Interest Calculation?

Credit card interest calculation in Bangladesh follows a standard formula that considers your average daily balance, monthly interest rate, and the number of days in your billing cycle. Understanding this calculation helps you better manage your credit card payments and avoid unnecessary interest charges.

2. How Does the Calculator Work?

The calculator uses the standard credit card interest formula:

\[ I = \frac{(ADB \times R \times D)}{(100 \times 30)} \]

Where:

\( ADB \) — Average Daily Balance (BDT)
\( R \) — Monthly Interest Rate (%)
\( D \) — Number of Days in Billing Cycle
\( I \) — Interest Amount (BDT)

Explanation: The formula calculates interest based on your average daily balance throughout the billing cycle, applying the monthly interest rate proportionally to the number of days.

5. Frequently Asked Questions (FAQ)

Q1: What is Average Daily Balance (ADB)?

A: Yes, different credit card issuers and different types of cards may have varying interest rates. Always check your card's terms and conditions.
