1. What is Credit Card Amortization?

Amortization is the process of paying off debt with regular payments over time. For credit cards, each payment is divided between interest charges and principal reduction.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( R \) — Monthly interest rate (APR / 12, as a decimal)
• \( D \) — Monthly payment amount
• Outstanding Balance — Remaining principal at start of month

Explanation: Each payment first covers the interest due, with the remainder applied to reduce the principal balance.

3. Importance of Amortization Schedule

Details: Understanding your amortization schedule helps you see how much of each payment goes toward interest versus principal, and how long it will take to pay off your balance.

4. Using the Calculator

Tips: Enter your current credit card balance, annual percentage rate (APR), and your planned monthly payment amount. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why does most of my payment go to interest at first?
A: When your balance is highest, more interest accrues. As the balance decreases, more of each payment goes toward principal.

Q2: How can I pay off my credit card faster?
A: Increase your monthly payment amount. Even small increases can significantly reduce total interest and payoff time.

Q3: What happens if I make only minimum payments?
A: Minimum payments mostly cover interest, resulting in much longer payoff times and higher total interest costs.

Q4: Does this calculator account for new charges?
A: No, this assumes no additional charges are made to the card during payoff.

Q5: How accurate is this calculator?
A: It provides a good estimate, but actual results may vary slightly due to rounding or billing cycle differences.
