How this is calculated
Each month, interest is added to the balance and your payment is subtracted — this is simulated month by month until the balance reaches zero, since credit card interest compounds on a shrinking (or growing) balance rather than following a fixed amortization schedule.
Frequently asked questions
Why does it say I'll never pay it off?
If your monthly payment is lower than the interest charged each month, the balance grows instead of shrinking — you'd need to increase your payment to make progress.
Does this account for new purchases?
No — this assumes no new spending on the card, just paying down the existing balance.
