Credit Card Repayment Formula:
From: | To: |
This calculator estimates how long it will take to pay off your credit card debt when making fixed monthly payments, accounting for compound interest.
The calculator uses the following formula:
Where:
Explanation: The formula calculates how many months it will take to pay off the debt when making fixed monthly payments that exceed the accrued interest.
Details: Understanding your repayment timeline helps with financial planning and shows how increasing payments can dramatically reduce payoff time and interest costs.
Tips: Enter your current credit card balance, the fixed monthly payment you can afford, and your card's annual percentage rate (APR). The calculator will estimate your payoff timeline.
Q1: Why does my payment need to exceed the interest?
A: If your payment only covers the interest (or less), your principal balance won't decrease and you'll never pay off the debt.
Q2: How can I pay off my credit card faster?
A: Increase your monthly payment amount, even slightly. Each extra dollar goes directly toward reducing your principal.
Q3: Does this account for minimum payments?
A: No, this assumes fixed payments. Minimum payments often start at 1-3% of balance and extend payoff time significantly.
Q4: What if my APR changes?
A: This calculation assumes a fixed APR. If your rate changes, you'll need to recalculate.
Q5: Are there other factors that affect payoff time?
A: Yes - additional charges to the card, late fees, or changes to your payment amount will all affect the actual payoff time.
