How to Use This Calculator
1. Enter your current credit card balance in the 'Current Balance' field. 2. Input your card's Annual Percentage Rate (APR) — you can find this on your monthly statement or card agreement. 3. Choose your payment strategy: either a fixed monthly payment amount or a target number of months to pay off the balance. 4. If you selected 'Fixed Monthly Payment,' enter the amount you plan to pay each month. If you selected 'Pay Off in a Set Number of Months,' enter your desired payoff period. 5. Click 'Calculate' to instantly see your estimated payoff date, total interest paid, and total amount paid.
How Credit Card Interest Works
Credit card interest is calculated using your Annual Percentage Rate (APR), which is divided by 12 to get your monthly periodic rate. Each month, interest is charged on your remaining balance before your payment is applied. This is why even a small reduction in your balance can save a significant amount in interest over time.
Fixed Monthly Payment Formula
When you make a fixed monthly payment, the number of months required to pay off your balance is calculated using the following formula:
- n = -log(1 − (r × B) / P) / log(1 + r)
- Where n is the number of months, r is the monthly interest rate (APR ÷ 12), B is the current balance, and P is the monthly payment.
If your monthly payment is less than or equal to the interest charged that month, your balance will never decrease — this is why the calculator warns you when a payment is too low.
Required Payment for a Target Payoff Date
If you want to pay off your balance in a specific number of months, the required monthly payment is calculated with the standard amortization formula:
- P = B × r × (1 + r)^n / ((1 + r)^n − 1)
- This ensures your balance reaches exactly zero by the end of your target period.
Why Paying More Than the Minimum Matters
Credit card minimum payments are typically set at 1–3% of your balance or a flat amount, whichever is greater. Paying only the minimum means the vast majority of your payment goes toward interest, and you could take decades to pay off even a modest balance. Increasing your monthly payment — even by $25–$50 — can cut your payoff time dramatically and save hundreds or thousands of dollars in interest.
Example
A $5,000 balance at 20.99% APR with a $100 minimum payment would take over 8 years to pay off and cost more than $3,500 in interest. Raising that payment to $250/month cuts the timeline to under 2 years and reduces interest to roughly $500.
