1. What is a Credit Card Amortization Table?

A credit card amortization table shows how each payment is split between interest and principal, and how your balance decreases over time. It helps you understand the true cost of carrying credit card debt and how long it will take to pay off.

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:

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.

3. Importance of Amortization Calculation

Details: Understanding your amortization schedule helps you see how much interest you're paying and how increasing payments can dramatically reduce payoff time and total interest.

4. Using the Calculator

Tips: Enter your current balance, APR, and planned monthly payment. The calculator will show your complete payoff schedule and total interest paid.

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 principal reduces, more of each payment goes toward principal.

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

Q3: What if I can only make minimum payments?
A: Minimum payments often cover mostly interest, leading to very long payoff times. Try to pay more than the minimum whenever possible.

Q4: Does this calculator account for additional charges?
A: No, it assumes no new charges are added to the card. For accurate results, stop using the card while paying it off.

Q5: What's the best strategy to pay off multiple cards?
A: Two common methods: 1) Avalanche method (pay highest APR first) saves most money, 2) Snowball method (pay smallest balance first) provides psychological wins.
