How this estimate is calculated
We apply standard amortization at the 21.5% average US credit-card APR (Federal Reserve G.19 (Consumer Credit)). For each monthly payment, interest each month is the balance times the monthly rate (APR ÷ 12) and the rest reduces principal, until the $40,000 balance reaches zero. The minimum-payment row uses the common 1%-of-balance-plus-interest rule.

It depends on your payment. At $1,200 a month you'd pay about $21,452 in interest; minimum payments alone cost $70,612. A larger fixed payment or a 0% balance transfer cuts this sharply.
What's the fastest way to pay off $40,000?
