The Short Answer
If you carry a balance on a credit card, the math punishes you harder than almost any other consumer debt. Federal Reserve G.19 data for Q1 2026 shows commercial-bank credit card APRs around 21% overall and about 21.5% for accounts assessed interest. Many consumer cards and store cards are higher, and most issuers compound interest daily.
For current benchmark rates, see the Federal Reserve's Consumer Credit G.19 release.
The fastest path out is some version of: stop adding new charges, pay much more than the minimum, and direct extra payments to the highest-APR card first. Everything below is detail on top of that core idea.
Run Your Numbers
Before picking a strategy, see what your current minimum payments are actually costing you. The default scenario (a $5,000 balance at 22% APR paying $150/month) is closer to most people than they expect:
Why Minimum Payments Are a Trap
The minimum payment on most credit cards is calculated as the greater of $25 or about 2% of the balance. That sounds reasonable until you do the math:
- $5,000 balance × 2% = $100/month minimum
- At 22% APR, interest alone is about $90 in the first month
- Only $10 actually reduces your balance
At that pace, a $5,000 balance takes roughly 30 years to pay off and costs about $13,000 in interest — almost three times the original debt.
Doubling the payment to $200/month cuts payoff to about 3 years and interest to ~$1,700. The marginal dollar above the minimum is enormously high-leverage.
Avalanche vs. Snowball
The two well-known strategies for prioritizing multiple cards:
| Avalanche (math-optimal) | Snowball (motivation-optimal) | |
|---|---|---|
| Order | Highest APR first | Smallest balance first |
| Saves more money | Usually yes | Usually no |
| Faster early wins | Usually no | Usually yes |
| Best if | You're disciplined and the gap between APRs is large | You need visible progress to stay motivated |
Both methods make the same minimum payments on every card; the difference is which one gets the extra dollars.
A concrete example — three cards:
- Card A: $3,000 at 26% APR
- Card B: $1,500 at 19% APR
- Card C: $800 at 24% APR
Avalanche order: A → C → B. Snowball order: C → B → A.
If you can throw an extra $300/month at the highest-priority card, avalanche pays off all three in about 16 months and costs ~$700 in interest. Snowball takes about 17 months and costs ~$820. The difference is real but small — the bigger factor is showing up every month, which is why snowball often wins in practice even though it's mathematically worse.
Balance Transfer Cards
If your credit score is good (typically 670+), a 0% intro APR balance transfer card can buy you 12–21 months of interest-free payoff time. The catch:
- Most charge a 3–5% transfer fee upfront
- The 0% rate expires — any remaining balance jumps to the regular APR (often 20%+)
- You usually can't transfer between cards from the same issuer
A balance transfer makes sense if you have a concrete plan to pay off the full balance before the promo ends. If you can't, you've just delayed the problem and paid a 3% fee for the privilege.
How Much Extra Should You Pay?
A rough framework:
- Minimum payment — barely a strategy; treat it as the floor, not the goal
- 2× the minimum — gets you out in 5–7 years for a typical balance
- 5× the minimum or 10% of balance — gets you out in 12–24 months
- Everything you can spare — fastest, but leave a small emergency buffer so an unexpected bill doesn't put you back on the card
Even a fixed extra $50/month makes a substantial difference. The compound interest blog shows the same math working in reverse — what helps you on investments hurts you on debt.
When Debt Consolidation Makes Sense
A personal loan or HELOC at a lower rate can refinance high-APR card debt:
- Personal loan — usually a fixed payment over 3–5 years, often lower than card APR for good-credit borrowers
- HELOC — can be cheaper, but uses your home as collateral and usually has a variable rate
- 401(k) loan — may be cheap on paper, but it disrupts retirement compounding and can create tax problems if you leave your job
Consolidation only helps if you stop using the original cards. Otherwise you end up with both the consolidation loan and a new card balance — the most common way consolidation backfires.
Quick Wins That Aren't About Strategy
A few things that move the number without picking avalanche vs snowball:
- Call your issuer and ask for a lower APR. Customers with on-time payment history often get a 2–5 point reduction just by asking.
- Make payments twice a month instead of once. On daily-compounded cards, the average daily balance drops, and so does the interest charge.
- Stop using the card for the payoff period. Set up direct debit for utilities and groceries on a debit card so the credit card balance can only go down.
Key Takeaways
- Minimum payments at roughly 21–22% APR can keep a $5,000 balance alive for decades
- Avalanche saves the most money; snowball builds the most momentum — pick the one you'll stick with
- A 0% balance transfer only helps if you actually clear the balance before the promo ends
- Calling for a rate reduction and paying twice a month are free wins
- Consolidation works only if you don't reload the original cards
