1. What is the Credit Card Repayment Formula?

The credit card repayment formula calculates how long it will take to pay off credit card debt when making fixed monthly payments. It accounts for compound interest and shows the relationship between principal, payments, and interest rates.

2. How Does the Calculator Work?

The calculator uses the credit card repayment formula:

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

Where:

$ P $ — Principal balance ($)
$ D $ — Monthly payment ($)
$ R $ — Monthly interest rate (annual rate / 12, as decimal)
$ T $ — Time to pay off (months)

Explanation: The formula calculates how many months it will take to pay off the debt by accounting for the diminishing principal and compound interest with each payment.

3. Importance of Repayment Calculation

Details: Understanding repayment timelines helps consumers make informed decisions about debt management, payment strategies, and financial planning.

4. Using the Calculator

Tips: Enter your current credit card balance, planned monthly payment, and annual interest rate. All values must be positive numbers, and your payment must be greater than the monthly interest charge.

5. Frequently Asked Questions (FAQ)

Q1: What if I can't make payments larger than the interest?
A: If your payment doesn't exceed the monthly interest, your debt will never be paid off (this is called "negative amortization").

Q2: How accurate is this calculator?
A: It provides a theoretical estimate assuming fixed payments and interest rates. Actual results may vary with changing rates or payment amounts.

Q3: What's the best strategy to pay off credit cards faster?
A: Pay more than the minimum, target highest-interest cards first (avalanche method), or consider balance transfers to lower-rate cards.

Q4: Does this account for minimum payments?
A: No, this calculates fixed payments. Minimum payments typically extend repayment periods significantly.

Q5: How can I reduce my repayment time?
A: Either increase your monthly payment or reduce your interest rate (through negotiation or balance transfers).
