1. What is the Balance Transfer Payoff Time Calculation?

This calculator estimates how long it will take to pay off a balance transfer credit card after the promotional period ends, taking into account the regular interest rate that will apply.

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:

$ P $ — Transferred balance including any fees ($)
$ D $ — Fixed monthly payment ($)
$ R $ — Monthly interest rate (annual rate ÷ 12, as decimal)
$ T $ — Time to pay off balance (months)

Explanation: The formula calculates how many months it will take to pay off the balance when making fixed monthly payments with interest accruing each month.

3. Importance of Calculating Payoff Time

Details: Knowing your payoff time helps you understand the true cost of a balance transfer after the promotional period ends, allowing you to make informed decisions about credit card usage and debt repayment strategies.

4. Using the Calculator

Tips: Enter your total transferred balance (including any transfer fees), your planned monthly payment amount, and the annual interest rate that will apply after the promotional period ends.

5. Frequently Asked Questions (FAQ)

Q1: What if my payment is too low to pay off the balance?
A: The calculator will show "∞" if your monthly payment is less than the monthly interest charges, meaning you'll never pay off the balance at that payment rate.

Q2: Does this include the promotional period?
A: No, this calculates the payoff time after the promotional period ends and regular interest rates apply.

Q3: Should I include the balance transfer fee?
A: Yes, include any transfer fees in your balance amount as they're part of what you owe.

Q4: What's a good monthly payment amount?
A: Ideally, pay enough to clear the balance before the promotional period ends. If not, pay as much as you can afford to minimize interest.

Q5: How accurate is this calculation?
A: It assumes fixed monthly payments and interest rate. Actual results may vary slightly due to rounding in real credit card statements.
