1. What is Credit Card Amortization?

Amortization is the process of spreading out debt payments over time through regular installments. For credit cards, each payment is divided between interest charges and principal reduction.

2. How the Calculator Works

The calculator uses these formulas:

Where:

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

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

3. Importance of Amortization

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

4. Using the Calculator

Tips: Enter your current credit card balance, APR (annual percentage rate), and your planned monthly payment amount. The calculator will show your repayment timeline.

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 payment goes toward principal.

Q2: How can I pay off my credit card faster?
A: Increase monthly payments, make biweekly payments, or reduce spending to free up more money for debt repayment.

Q3: What if my payment is less than the interest?
A: Your balance will grow (negative amortization). You'll never pay off the debt without increasing payments.

Q4: Does this account for minimum payments?
A: No, this assumes fixed payments. Credit card minimums are typically 1-3% of balance plus interest.

Q5: How accurate is this calculator?
A: It assumes fixed APR and payments. Real credit cards may have variable rates and different payment allocation methods.
