1. What is the Credit Card Repayment Calculator?

This calculator estimates how long it will take to pay off your credit card debt when making fixed monthly payments, accounting for compound interest.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ T = \frac{\log\left(\frac{P}{P - D \times R}\right)}{\log(1 + R)} \]

Where:

Explanation: The formula calculates how many months it will take to pay off the debt when making fixed monthly payments that exceed the accrued interest.

3. Importance of Credit Card Repayment Calculation

Details: Understanding your repayment timeline helps with financial planning and shows how increasing payments can dramatically reduce payoff time and interest costs.

4. Using the Calculator

Tips: Enter your current credit card balance, the fixed monthly payment you can afford, and your card's annual percentage rate (APR). The calculator will estimate your payoff timeline.

5. Frequently Asked Questions (FAQ)

Q1: Why does my payment need to exceed the interest?
A: If your payment only covers the interest (or less), your principal balance won't decrease and you'll never pay off the debt.

Q2: How can I pay off my credit card faster?
A: Increase your monthly payment amount, even slightly. Each extra dollar goes directly toward reducing your principal.

Q3: Does this account for minimum payments?
A: No, this assumes fixed payments. Minimum payments often start at 1-3% of balance and extend payoff time significantly.

Q4: What if my APR changes?
A: This calculation assumes a fixed APR. If your rate changes, you'll need to recalculate.

Q5: Are there other factors that affect payoff time?
A: Yes - additional charges to the card, late fees, or changes to your payment amount will all affect the actual payoff time.
