Credit Card Payoff Formula:
From: | To: |
The credit card payoff formula estimates the time required to pay off credit card debt when making biweekly payments with additional extra payments. It accounts for the principal balance, interest rate, regular payments, and any extra payments.
The calculator uses the following formula:
Where:
Explanation: The formula calculates how many months it will take to pay off the debt by accounting for the reduced principal from extra payments and the compounding interest.
Details: Understanding your payoff timeline helps with financial planning, saving money on interest, and motivating debt repayment strategies.
Tips: Enter your current credit card balance, any extra payment you can make, your regular biweekly payment amount, and your APR. All values must be positive numbers.
Q1: Why use biweekly payments instead of monthly?
A: Biweekly payments result in 26 half-payments per year (equivalent to 13 monthly payments), which can help pay off debt faster and reduce interest.
Q2: How accurate is this calculator?
A: It provides a good estimate but actual results may vary slightly due to rounding in real credit card statements and potential changes in interest rates.
Q3: What if my minimum payment changes?
A: This calculator assumes fixed payments. If your minimum payment decreases as your balance decreases, payoff time may be longer.
Q4: How does the extra payment affect payoff time?
A: Even small extra payments can significantly reduce payoff time by decreasing the principal balance faster and reducing interest charges.
Q5: What if I get an "invalid inputs" message?
A: This means your payments are too low to cover the interest charges, so you'll never pay off the debt with those payment amounts.
