1. What is the Balance Transfer Interest Calculation?

The balance transfer interest calculation determines how much interest you'll pay after the promotional 0% APR period ends on your credit card. It helps you plan for post-promotion costs when transferring balances between credit cards.

2. How Does the Calculator Work?

The calculator uses the simple interest equation:

Where:

• \( P \) — Principal balance ($)
• \( R \) — Monthly interest rate (annual rate / 12, as decimal)
• \( I \) — Monthly interest ($)

Explanation: The equation calculates the monthly interest you'll pay on your transferred balance after the promotional period ends.

3. Importance of Interest Calculation

Details: Understanding your post-promotional interest helps evaluate whether a balance transfer makes financial sense and allows for better repayment planning.

4. Using the Calculator

Tips: Enter your remaining balance at the end of the promotional period and the card's standard annual percentage rate (APR). All values must be positive numbers.

Q3: Are there fees for balance transfers?
A: Most cards charge 3-5% of the transferred amount as a fee, which isn't included in this calculation.

Q4: What if my APR changes?
