Credit Card Payoff Equation:
From: | To: |
The Bankrate Credit Card Payoff Calculator estimates how long it will take to pay off credit card debt based on your current balance, monthly payment, and interest rate. It uses the standard mathematical formula for loan payoff time.
The calculator uses the following equation:
Where:
Explanation: The formula calculates how many months it will take to pay off the debt given the compounding interest and fixed monthly payments.
Details: Knowing your payoff timeline helps with financial planning, debt management, and understanding the true cost of carrying credit card debt.
Tips: Enter your current credit card balance, the fixed monthly payment you can afford, and your card's APR. The calculator will show how long it will take to become debt-free.
Q1: Why does my payment need to exceed the monthly interest?
A: If your payment only covers interest (D ≤ P × R), your principal will never decrease and you'll never pay off the debt.
Q2: How can I pay off my debt faster?
A: Either increase your monthly payment or reduce your interest rate (through balance transfers or negotiating with your card issuer).
Q3: Does this account for minimum payments?
A: No, this assumes fixed payments. Minimum payments typically start at 1-3% of balance and change as your balance changes.
Q4: What if I make additional payments?
A: Extra payments will reduce your payoff time. Re-calculate with your new average monthly payment amount.
Q5: How accurate is this calculator?
A: It provides a mathematical estimate assuming fixed payments and interest rate. Actual results may vary slightly due to billing cycles and rounding.
