How to use this tool
- Enter your own figures over the defaults — Card balance, APR, Monthly payment.
- The answer updates as you type. There is no button, and nothing is sent anywhere.
- Change APR on its own to see how much it moves the result — the worked example below shows exactly that.
Card interest compounds monthly at rates that dwarf almost any investment return. Paying more than the minimum has an outsized effect — try increasing the payment slightly and watch the timeline collapse.
How it works
This takes 3 inputs — card balance, apr, monthly payment — and returns time to clear, total interest paid and total paid. The whole calculation happens in this page as you type: there is no submit button, no request, and nothing stored.
Because it recalculates on every keystroke you can use it as a sensitivity test rather than a one-shot answer. Moving apr alone from 22.9 to 23.9 changes time to clear from 2 yr 9 mo to 2 yr 9 mo — the worked example below sets that out in full.
A worked example
Worked through with the figures the page already has in it: card balance of 6,000 and apr of 22.9 %, and the rest as shown, giving time to clear of 2 yr 9 mo. These numbers come from running the calculator’s own code, not from being typed in here, so they cannot drift away from what you see on screen.
Starting from:
- Card balance: 6,000
- APR: 22.9 %
- Monthly payment: 250
| Result | Value |
|---|---|
| Time to clear | 2 yr 9 mo |
| Total interest paid | 2,100.76 |
| Total paid | 8,100.76 |
Credit Card Payoff Calculator — frequently asked questions
Why does the minimum payment take so long?
Minimums are typically set at 1–3% of the balance, barely above the interest charge. At that rate a balance can take decades to clear and cost more in interest than the original spending.
Should I pay the highest rate or smallest balance first?
Mathematically, highest interest rate first costs least. Psychologically, clearing the smallest balance first builds momentum. Both work; the one you stick with wins.
Is a balance transfer worth it?
Often, if you clear the balance within the promotional period and account for the transfer fee. If you do not, the post-promotional rate can be worse than where you started.
Is this calculator free?
Yes, with no account, no limits and no data collection. It runs entirely in your browser.
Should I rely on this for a financial or medical decision?
No. It is a planning estimate built on standard formulas and stated assumptions. For decisions that matter, speak to a qualified professional who can account for your full circumstances.
How accurate is the Credit Card Payoff figure?
The arithmetic is exact. With the defaults on this page — card balance 6000, apr 22.9 %, monthly payment 250 — it returns time to clear of 2 yr 9 mo. What limits accuracy is the assumptions, not the maths: change apr to 23.9 % and the same formula gives 2 yr 9 mo. Treat it as a well-founded estimate, not a quotation.
