Credit Card Payoff Calculator
Enter your credit card details and see exactly how long it will take to pay off, how much interest you will pay, and what happens when you throw extra money at it each month.
Your credit card
Unburden tracks them all.
One card payoff is a start. But most people carry multiple debts. The Unburden app manages every card, loan, and line of credit in one place and updates as you pay them down.

When you have multiple cards, strategy matters.
Momentum is mathematically constrained to match or beat Avalanche on total interest, while giving you the quick wins that keep you going. It dynamically adapts to your specific debt profile. Only in the Unburden app.
You found out what your card is costing you. Now do something about it.
How credit card interest actually works
Credit card interest is not calculated once a month on your statement balance. It compounds daily. Your card issuer takes your APR, divides it by 365 to get the daily periodic rate, then multiplies that rate by your current balance every single day. The result is added to your accrued interest, and at the end of the billing cycle, that interest gets folded into your balance.
This means interest accrues on interest. A 22% APR does not cost you exactly 22% of your balance per year. Because of daily compounding, the effective annual rate is slightly higher. On a $5,000 balance, that difference can mean hundreds of extra dollars over the life of the debt.
Most people think of interest as a percentage of their balance. The daily compounding model means that every day you carry a balance, the cost increases. Paying even a few days earlier in the billing cycle can reduce the interest you owe that month.
The minimum payment trap
Credit card minimum payments are designed to keep you in debt. Most issuers set the minimum at 1% to 2% of your outstanding balance, or a flat dollar floor (typically $25), whichever is greater. When your balance is high, most of that minimum goes toward interest. The amount hitting your actual principal is tiny.
Run the numbers on a $5,000 balance at 22% APR with a 2% minimum payment. The initial minimum is $100, but $91.67 of that is interest. You are reducing your principal by $8.33 in the first month. At that rate, it takes more than 30 years to pay off and you pay more than $12,000 in interest. You pay back nearly three and a half times what you originally owed.
The minimum payment is not a recommendation. It is the amount that maximizes profit for the issuer while keeping you from going delinquent. Treating it as your standard payment is the most expensive way to carry credit card debt.
How extra payments change everything
Even modest extra payments have an outsized effect on credit card debt because they go directly toward principal. When you pay $50 above the minimum, that entire $50 reduces your balance. Next month, interest is calculated on a lower balance, which means more of your minimum payment also goes toward principal. The effect compounds in your favor.
On that same $5,000 balance at 22% APR, adding $50 per month to a $150 minimum payment cuts your payoff time from around 4 years to under 3 years and saves over $1,500 in interest. Adding $100 extra drops it further. The first $50 has a bigger proportional impact than the next $50, which means the most important step is making any extra payment at all.
This calculator shows one card at a time. Unburden tracks every debt you have, compares payoff strategies across all of them, and updates as your balances change. Free to start, and your data never leaves your device.
What is the Burden Score?
Your credit score measures your value to lenders. The Burden Score measures your risk to yourself. It is a 0-100 educational estimate built on five proprietary stress signals that capture how much pressure your debt is actually putting on your life. A 780 credit score and a Critical Burden Score can exist on the same person.
This calculator tells you when you will pay off one card. The Burden Score tells you how vulnerable you are right now across all of your debt. You can find yours free in the Unburden app in about 60 seconds.
Why a calculator is not enough
A calculator gives you a snapshot. It tells you what would happen if everything stays exactly the same: same balance, same rate, same payment, every month until the end. That is useful for about ten seconds.
Real credit card debt does not work that way. You make a large purchase one month. Your rate goes up after a promo period ends. You transfer a balance from another card. You miss a payment and get hit with a penalty APR. A static calculator cannot keep up with any of that.
Unburden is the app this calculator wishes it could be. Add all your cards and debts. Watch your Burden Score drop in real time as you pay them down. Run what-if scenarios to see what happens if you shift $200 from one card to another. Get reminders before due dates. Free to start and your financial data never leaves your device.
