1. What is Balance Transfer Calculation?

The balance transfer calculation helps determine how long it will take to pay off a credit card balance transfer offer, considering both the promotional 0% interest period and the post-promotional interest rate period.

2. How Does the Calculator Work?

The calculator uses two equations:

\[ T = P / D \text{ (during 0% period)} \] \[ T = \frac{\log(P / (P - D \times R))}{\log(1 + R)} \text{ (post-promotional)} \]

Where:

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

Explanation: During the 0% period, payments directly reduce the balance. After the promotional period, interest accrues and the calculation accounts for compound interest.

3. Importance of Balance Transfer Calculations

Details: Understanding the true cost and payoff timeline of balance transfers helps consumers make informed decisions about credit card offers and debt repayment strategies.

4. Using the Calculator

Tips: Enter the total transferred balance (including any fees), your planned monthly payment, the post-promotional annual interest rate, and the length of the 0% promotional period.

5. Frequently Asked Questions (FAQ)

Q1: Should I include the balance transfer fee in P?
A: Yes, the transferred balance (P) should include both the amount you're transferring and any balance transfer fee.

Q2: What if I pay more than the minimum payment?
A: The calculator works with whatever fixed monthly payment amount you enter. Higher payments will reduce payoff time.

Q3: How accurate is this calculation?
A: It provides a good estimate assuming fixed payments and interest rates. Actual results may vary slightly due to rounding in real credit card statements.

Q4: What if I have no promotional period?
A: Simply enter 0 for the promotional period and the calculator will use only the post-promotional formula.

Q5: Can I use this for other types of loans?
A: The post-promotional formula works for any fixed-payment, fixed-rate amortizing loan.
