The honest answer comes down to two numbers: what you owe, and what you pay each month. Everything else is detail. But the way those two numbers interact surprises almost everyone who sees it worked out, so let's work it out, with a balance close to the current American average and a rate to match.

The setup

Say you owe $5,000 at 21% APR, which is roughly what the Federal Reserve reports as the average rate on cards that actually carry interest in 2026. Your statement helpfully offers a minimum payment, and this month it's around $137. Reasonable, right?

What minimum payments actually do

A typical minimum is calculated as that month's interest plus 1% of your balance. Notice what that design does: it shrinks as your balance shrinks. You pay less and less, the balance falls slower and slower, and the card earns interest the whole way down.

Run that to the end and the $5,000 takes about 16 years to clear, with $7,291 in interest. You'd pay $12,291 for $5,000 of spending, and the card would outlast most marriages, every phone you'll ever own, and possibly the dog.

Nobody chooses that on purpose. It happens because the minimum feels like the "official" payment, when it's really the slowest legal exit.

What one fixed payment does instead

Now take the same $5,000 at 21% and pay a flat amount every month, never letting it shrink:

  • $100 a month: 10 years, $6,986 in interest. Barely ahead of the minimums, because the first month's interest alone is $87.50. This is the payment that feels responsible but mostly treads water.
  • $150 a month: 4 years 3 months, $2,570 in interest.
  • $200 a month: 2 years 10 months, $1,633 in interest.
  • $250 a month: 2 years 1 month, $1,208 in interest.

Sit with the middle of that list for a second. The difference between $150 and $200 a month is $50, about one takeout order a week. That $50 buys back 17 months of your life and $937 in interest. There aren't many places in your budget where $50 works that hard.

The two rules that make the math work

First, fix your payment. Pick a number you can sustain, set it on autopay, and never let it drift down toward the minimum. The entire trap in the first example is the shrinking payment; a flat payment dismantles it.

Second, stop adding while you're subtracting. New charges on a card you're paying down are a treadmill. Most people do better moving day-to-day spending to a debit card until the balance is gone; it removes the question entirely.

What about a 0% balance transfer?

A transfer card can genuinely help by pausing interest for 12 to 21 months, but only if the spending that built the balance has stopped, and only if you do the division: balance divided by promo months equals the payment that actually clears it before the rate snaps back. Mind the 3% to 5% transfer fee, and treat the new card as a payoff tool, not new room to spend.

Your card isn't average

Your balance, your APR, and your spare cash are different from this example, and if you have more than one card the payoff order matters too. Our free debt payoff calculator takes your real debts and hands back debt-free dates, total interest, and a month-by-month plan, including the snowball vs. avalanche comparison we break down in this post. Everything runs in your browser; nothing you type leaves your device.

If the payment is becoming hard to make at all, deal with that first: our guide to requesting credit card forbearance covers exactly what to say. And if you want a partner in building the payoff plan around your real budget, that's what a free Financial Freedom Assessment is for.

The examples above assume a 21% APR, monthly compounding, and a minimum payment of interest plus 1% of the balance with a $35 floor. Your card's terms will differ; the pattern won't.
