How to Pay Off Credit Card Debt at 21% Interest
See your own safe-to-spend number Free paycheck budget, set up in 60 seconds →To pay off credit card debt at today's 21%-plus interest rates, budget a fixed extra payment every paycheck, on top of the minimum. On a $6,000 balance, the minimum alone takes over 20 years and costs about $9,500 in interest. Adding $100 a month cuts that to under 4 years and about $2,300. The budget is where the $100 comes from.
Minimum payments vs a budgeted extra payment
$6,000 balance at 21.19% APR. The minimum is interest plus 1% of the balance (at least $25), a common card formula. No new charges.
Minimum = interest + 1% of balance, $25 floor. Calculated monthly.
| Monthly payment | Time to pay off | Total interest |
|---|---|---|
| Minimum only | 20.6 years | $9,548 |
| Minimum + $100 | 3.8 years | $2,333 |
| Minimum + $200 | 2.2 years | $1,375 |
Where the extra $100 comes from
$100 a month is $46 a paycheck if you're paid every two weeks. In most budgets it's already there, spread across small purchases nobody planned. A paycheck budget finds it by doing the bills first:
- List the bills due before your next payday, including the card minimum.
- Add the extra payment as a bill. Same amount, every paycheck.
- What's left is your spending money until payday. Divide it by the days left.
If the number left is too small, trim one flexible category until it fits. Don't drop the extra payment first; it's the line doing the most work.
Snowball or avalanche?
With several cards, the debt snowball pays the smallest balance first for quick wins; the avalanche pays the highest rate first and costs a bit less in interest. The one you stick with is the better one. Either way, when a card is paid off, its payment rolls into the next card, so the extra amount grows without changing your budget.
Should I use a balance transfer instead?
A 0% balance transfer can help, but it only works with a budget behind it: there's usually a 3% to 5% transfer fee, and whatever's left when the promotion ends goes back to a high rate. Divide the balance by the promotional months to get the payment you need, and put that in the budget.
