How to Use?
- 1
Choose what you want to calculate
By default, the calculator computes how many months it takes to pay off your balance. Switch to Required Monthly Payment mode to find out how much you need to pay each month to hit a target payoff date.
- 2
Enter your balance and interest rate
Type your current credit card balance and the annual percentage rate (APR) from your statement. The APR is typically found in the rates and terms section of your monthly bill.
- 3
Enter your monthly payment or target period
In Payoff Months mode, enter how much you can pay each month. In Required Payment mode, enter how quickly you want to be debt-free.
- 4
Choose the time display unit
Use the inline unit selector next to the mode dropdown to display payoff time in months or years. The calculator converts automatically and updates the label and gauge accordingly.
- 5
Review the results and amortisation schedule
The calculator shows time to pay off, total amount paid, and total interest. The amortisation table breaks down each payment into interest and principal portions so you can see exactly how your balance declines.
- 6
Enable Advanced Mode for realistic planning
Toggle Advanced Mode to add extra monthly payments and estimate new charges. The calculator compares your accelerated plan against the base case and shows how many months and how much interest you save.

Frequently Asked Questions
Making only the minimum payment, which is typically 1% to 3% of your balance plus interest, can extend your payoff period to decades and cost you many times the original balance in interest. For example, a $5,000 balance at 20% APR with a 2% minimum payment ($100 initially) takes over 86 months to pay off and costs more than $3,600 in interest. Every dollar above the minimum goes directly toward reducing principal and shortening your payoff timeline.
Extra payments have a leveraged effect because every additional dollar reduces the principal balance that future interest is calculated on. Adding $25 per month to a $150 payment on a $5,000 balance at 20% APR cuts the payoff time from 46 months to 37 months and saves roughly $400 in interest. Adding $50 per month drops the time to 31 months and saves over $700. The calculator lets you model any extra payment amount with the Advanced Mode.
A good rule is to pay at least 2 to 3 times the minimum payment. If your minimum payment is $100, aim for $200 to $300 per month. This significantly reduces both payoff time and total interest. For the fastest payoff, pay as much as you can afford while maintaining your essential expenses and emergency fund. The calculator shows you the exact tradeoff between payment amount, payoff time, and total interest for any scenario.
The interest rate determines how much of each payment goes toward interest versus principal. At 15% APR, the monthly rate is 1.25%, so a $5,000 balance accrues $62.50 in interest each month. At 24% APR, the same balance accrues $100 in monthly interest. This difference of $37.50 per month means higher-rate debt takes longer to pay off and costs more, even with the same payment amount. A balance transfer to a lower-rate card can save hundreds or thousands in interest.
The snowball method focuses on paying off the smallest balance first while making minimum payments on all other debts. The avalanche method targets the highest-interest debt first. The snowball method provides psychological wins that keep you motivated, while the avalanche method saves the most money in interest. For credit card debt specifically, the avalanche method is usually mathematically superior because credit card rates vary widely, and the highest-rate card costs the most. However, the best method is the one you stick with consistently.
A balance transfer moves your debt to a card with a lower interest rate, often 0% APR for a promotional period of 12 to 21 months. The transfer typically costs 3% to 5% of the transferred amount. If you transfer a $5,000 balance and pay $200 per month, you can clear the debt within the promotional period and pay zero interest. Without the transfer, the same payment at 20% APR takes 31 months and costs $1,200 in interest. Use this calculator with the lower promotional rate to see the exact savings. Pay off the balance before the promotional period ends to avoid deferred interest charges.
Using savings to pay off high-interest credit card debt makes mathematical sense because the interest you save (15% to 25% APR) almost certainly exceeds what your savings earn (3% to 5% APY). However, you should keep an emergency fund of 3 to 6 months of essential expenses before making a large lump-sum payment. If depleting your savings would leave you vulnerable to a job loss or medical emergency, it is safer to pay down the debt gradually. A good compromise is to use half of your available savings for a lump-sum payment while keeping the rest as a safety net.
Most credit cards calculate interest daily using the daily periodic rate (APR divided by 365). This means interest accrues on your balance every single day, and the next day's interest is calculated on a slightly higher balance. Daily compounding results in a higher effective annual rate than monthly compounding at the same APR. A 20% APR compounded daily has an effective rate of approximately 22.13%, compared to 21.94% compounded monthly. The difference is modest on small balances but adds up on larger, long-term debt. This calculator uses monthly compounding, which is slightly conservative compared to most cards' daily methods.
Missing a payment triggers a late fee of up to $41 and can cause your APR to increase to the penalty rate, which can be as high as 29.99%. Late payments also damage your credit score by up to 100 points if reported to the credit bureaus after 30 days. To avoid missed payments, set up auto-pay for at least the minimum amount due. If you miss a payment, make it as soon as possible and call your card issuer to request a late fee waiver, which many issuers grant for first-time or infrequent offenses.
Credit utilization is the ratio of your total credit card balances to your total credit limits. It accounts for 30% of your FICO score. As you pay down your balance, your utilization drops, which typically improves your credit score. For example, paying a $4,000 balance down to $2,000 on a card with a $10,000 limit reduces utilization from 40% to 20%, which can increase your score by 20 to 40 points. Keeping utilization below 30% is recommended, and below 10% is ideal for the highest scores.
A reasonable target is 12 to 24 months for most credit card balances under $10,000. Longer than 24 months means you are paying significant interest, and shorter than 12 months may strain your monthly budget. Use the Required Payment mode to find the monthly payment that hits your target payoff date. For example, paying off $6,000 at 20% APR in 18 months requires a monthly payment of approximately $390 and costs about $1,020 in interest. Stretching to 36 months drops the payment to $223 but increases total interest to $2,028.
New purchases add to your balance and accrue interest from the day they post if you carry a balance from the previous month. This is because credit cards do not offer a grace period on new purchases when you have an existing balance. Each new purchase extends your payoff timeline and increases total interest. In the Advanced Mode, you can estimate monthly new charges to see their impact. For example, adding $100 in new charges each month to a $4,000 balance at 20% APR with a $200 payment increases payoff time from 24 months to 37 months and adds $350 in extra interest.
Yes, you can request a lower APR from your card issuer, especially if you have a good payment history and strong credit score. Call the number on the back of your card and ask to speak with the retention or customer loyalty department. Mention competing offers from other issuers and request a rate reduction of 5% to 10%. Many issuers grant temporary or permanent reductions to retain customers. Even a 3% reduction on a $5,000 balance saves approximately $600 in interest over a 36-month payoff period. If the issuer refuses, consider a balance transfer to a lower-rate card.
Minimum payments are designed to maximise interest income for the card issuer, not to help you get out of debt. A $5,000 balance at 20% APR with a 2% minimum payment ($100 initially, declining as the balance drops) takes over 7 years to pay off and costs more than $3,600 in interest. The same balance with a fixed $200 payment is paid off in 31 months with $1,200 in interest. The difference of $2,400 is the cost of paying only the minimum. The calculator shows the exact numbers for your specific balance and rate so you can see the true cost of minimum payments for yourself.
