Credit card payoff, in short
How you pay a credit card balance down changes the outcome more than almost any other factor. A $5,000 balance at 18.99% APR paid at $200 a month clears in 33 months for $1,414.44 in interest. Left on minimum payments alone, that same balance takes 432 months — 36 years — and costs $15,458.49, more than triple the original debt.
Key takeaways
- $5,000 at 18.99% APR, paid at $200/month: 33 months to payoff, $1,414.44 total interest.
- The same balance on minimum payments (2% of balance or $25, whichever is greater): 432 months — 36 years — and $15,458.49 in interest.
- Doubling the payment to $400/month cuts payoff to 15 months and interest to $615.34 — less than half the time for less than half the cost of the $200/month plan.
- To clear the same $5,000 balance in exactly 24 months takes a $252.02 monthly payment.
How credit card interest actually compounds
Interest accrues on your balance every month at roughly APR ÷ 12. On $5,000 at 18.99% APR, the very first month generates about $79 in interest before your payment does anything to reduce principal. Whatever's left of your payment after covering that interest is what actually chips away at the balance — which is exactly why a payment barely above the interest charge takes forever to make real progress.
Why minimum payments are a trap
A typical minimum payment formula is 2% of the balance or a small flat floor, whichever is larger — starting around $100 a month on a $5,000 balance. Compare the two paths on the same $5,000 at 18.99% APR:
$200/month fixed: 33 months, $1,414.44 total interest
Minimum payments only: 432 months (36 years), $15,458.49 total interest
As the balance shrinks under minimum payments, the 2% minimum shrinks right along with it — so the payment keeps getting smaller even as it's supposed to be paying the debt off, stretching the tail end of the payoff out for decades.
What doubling your payment buys you
Going from $200 to $400 a month on the same $5,000 balance doesn't just cut the payoff time roughly in half — it does better than that. 33 months drops to 15, and total interest falls from $1,414.44 to $615.34, a bigger-than-proportional improvement, because less time carrying a balance means less time for interest to compound against you. Extra payments toward a credit card are usually the highest guaranteed return available in a typical budget, since you're avoiding a rate few investments reliably beat.
Working backward: payment for a target payoff date
If you'd rather set a deadline and work out what it takes to hit it, this calculator can flip the math around. To clear the same $5,000 balance in exactly 24 months requires a $252.02 monthly payment — a useful number when you're deciding whether a fixed timeline fits your budget before committing to it.
