How this estimate is calculated
We apply standard amortization at the 20% average Canadian credit-card APR (Bank of Canada — interest rates & financial data). For each monthly payment, interest each month is the balance times the monthly rate (APR ÷ 12) and the rest reduces principal, until the $20,000 balance reaches zero. The minimum-payment row uses the common 1%-of-balance-plus-interest rule.

Frequently asked questions
How long does it take to pay off $20,000 in credit card debt?
At the average 20% APR, $20,000 takes about 4 yr 2 mo to clear if you pay $600 a month. Paying only the minimum stretches it to 30 yr 4 mo and costs $32,317 in interest.
How much interest will I pay on $20,000?
It depends on your payment. At $600 a month you'd pay about $9,436 in interest; minimum payments alone cost $32,317. A larger fixed payment or a 0% balance transfer cuts this sharply.
What's the fastest way to pay off $20,000?
Pay as much above the minimum as your budget allows, target the highest-APR balance first (the avalanche method), and consider a 0% balance-transfer card or a lower-rate consolidation loan to stop interest while you pay it down.
