1. What is a Credit Card Amortization Schedule?

A credit card amortization schedule shows how each payment is split between principal and interest over time until the balance is paid off. It helps visualize the true cost of carrying credit card debt and how making larger payments can save money on interest.

2. How Does the Calculator Work?

The calculator uses these formulas:

\[ \text{Interest (month m)} = \text{Outstanding Balance} \times R \] \[ \text{Principal (month m)} = D - \text{Interest (month m)} \]

Where:

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

Explanation: Each payment first covers the interest due, then the remainder goes toward reducing the principal. As the principal decreases, less of each payment goes toward interest.

3. Importance of Amortization Calculation

Details: Understanding your amortization schedule helps you see how much interest you'll pay over time and how increasing payments can dramatically reduce both the repayment period and total interest paid.

4. Using the Calculator

Tips: Enter your current credit card balance, APR (annual percentage rate), and your planned monthly payment. The calculator will show how long it will take to pay off and the total interest cost.

5. Frequently Asked Questions (FAQ)

Q1: Why does most of my payment go to interest at first?
A: Early in repayment, your balance is highest so interest charges are largest. As you pay down principal, more of each payment goes toward reducing the balance.

Q2: How can I pay off my credit card faster?
A: Even small increases in monthly payments can significantly reduce repayment time and interest. Making biweekly payments (half your monthly amount every 2 weeks) results in one extra full payment per year.

Q3: What if I only make minimum payments?
A: Minimum payments typically cover mostly interest, resulting in very slow principal reduction and high total interest costs. This calculator assumes fixed payments above the minimum.

Q4: Does this calculator account for additional charges?
A: No, it assumes no additional purchases are made on the card. For accurate results, stop using the card while paying it down.

Q5: How accurate is this calculator?
A: It provides a good estimate, but actual results may vary slightly due to rounding or if your credit card company uses daily compounding interest.
