How Long to Pay Off a $20,000 Credit Card
Payoff time and total interest at a 22% APR by monthly payment.
Payoff by Monthly Payment (at 22% APR)
| Monthly payment | Time to pay off | Total interest |
|---|---|---|
| $500/mo | 6 yrs 1 mo (73 mo) | $16,378 |
| $750/mo | 3 yrs 1 mo (37 mo) | $7,708 |
| $1,000/mo | 2 yrs 2 mos (26 mo) | $5,143 |
| Minimum only (2%) | 100 yrs (1200 mo) | $164,649 |
Higher payments clear the balance faster and cut total interest. The minimum-payment row shrinks each month, which is why it takes so long.
The Minimum-Payment Trap
Paying only the minimum (about 2% of the balance, which falls as you pay down) would take 100 yrs and cost about $164,649 in interest on this $20,000 balance. Paying a fixed amount each month instead is dramatically faster and cheaper.
