Guide
How card interest works
Credit cards usually charge interest monthly at the APR divided by twelve on the balance you carry. If your payment is smaller than the interest, the debt never falls. The calculator steps through each month: it adds interest, subtracts your payment and counts the months until the balance reaches zero. The required-payment figure uses the standard loan formula for the target period.
Worked example
A balance of 5,000 at 20% APR with payments of 200 a month takes 33 months to clear and costs about 1,522 in interest. Raising the payment to 300 cuts the time to 20 months and the interest to about 907. To be debt-free in 12 months you would need to pay about 463 a month.
Why minimum payments are expensive
Minimum payments are often only 1–3% of the balance plus interest, which keeps you in debt for many years and can double the cost of what you bought. Paying a fixed amount above the minimum, and not adding new spending to the card, is the simplest way to get out of debt faster.
Strategies to pay off faster
If you have several cards, the avalanche method pays extra on the highest-rate card first and saves the most interest; the snowball method clears the smallest balance first for quick motivation. A balance transfer to a 0% promotional card or a lower-rate personal loan can reduce interest, but watch for transfer fees and the rate after the promotion ends. Selling unused items is another quick way to raise cash for a lump-sum payment; you can list them free on FastBuySale.

The calculator runs entirely in your browser; your balance and payments are never sent anywhere. Results are estimates, because card issuers may compound daily and add fees.

Frequently asked questions
What if my payment is less than the interest?
The balance will never fall. The calculator warns you and shows the minimum payment needed to make progress.
How is the monthly interest rate calculated?
The APR is divided by 12. For 24% APR that is 2% a month.
Is daily compounding included?
The calculator uses monthly compounding. Daily compounding can add slightly more interest.
Should I pay off cards or save first?
Many advisers suggest keeping a small emergency fund, then paying off high-interest cards because the interest saved is guaranteed.
Does a balance transfer help?
It can, if the fee is low and you clear the balance before the promotional rate ends.
