How to Pay Off Credit Card Debt: Avalanche vs Snowball
Loading article…
To pay off credit card debt, you need two things: a fixed monthly amount above your minimum payments, and an order for attacking your balances. The two classic orders are the avalanche method (highest interest rate first) and the snowball method (smallest balance first). Both work. On the $8,500 example below, the avalanche saves $344.53 in interest, while the snowball clears a first debt 13 months sooner. For more borrowing and repayment guides, visit our loans hub.
The Financial Consumer Agency of Canada (FCAC) describes both strategies. It notes that paying the highest rate first costs less, while paying the smallest balance first can keep you motivated but may cost more over time. Either way, you keep making the minimum payment on every debt.
Why credit card debt is so expensive
Credit cards charge some of the highest rates in consumer credit. In our catalogue, as of October 18, 2026, the purchase rate is 21.99% on both the TD Cash Back Visa* Card and the American Express Cobalt® Card. Low-rate cards exist: the MBNA True Line® Mastercard® charges 12.99% on purchases.
Interest also compounds when you carry a balance. Each month, unpaid interest is added to what you owe, and next month's interest is charged on that bigger number. That is why paying only the minimum can stretch a balance over years. Our guide to credit card interest explains how issuers calculate it.
Step 1: List every debt
Write down each balance, its interest rate and its minimum payment. Include cards, store cards, lines of credit and any personal loan. You cannot pick an order without this list.
Then set a monthly amount you can pay every month without new borrowing. Everything above the total of your minimums is your "extra" payment. That extra is what makes either method work.
The avalanche method
With the avalanche, you put the extra payment on the debt with the highest interest rate. You pay the minimum on everything else. When the first debt is gone, its full payment rolls to the next-highest rate.
This order minimizes interest because each extra dollar removes the most expensive debt first. It is the mathematically cheapest choice. The drawback: if your highest-rate debt is also large, the first win can take a long time.
The snowball method
With the snowball, you put the extra payment on the smallest balance, whatever its rate. When it is paid off, you roll its payment into the next smallest balance. The payment "snowballs" as each debt disappears.
The appeal is psychological. You close an account quickly, see progress and stay committed. The FCAC confirms this benefit, but also warns that the strategy may cost you more over time.
Avalanche vs snowball: a worked example
Take three debts totalling $8,500 and a budget of $350 a month:
- Card A: $4,500 at 22.99%, minimum of $135
- Card B: $2,500 at 19.99%, minimum of $75
- Line of credit: $1,500 at 10.45%, minimum of $45
The minimums add up to $255, so $95 a month is extra. For simplicity, minimums stay fixed in this example, and interest is calculated monthly. The rates are illustrative, not offers.
| Strategy | Order of payoff | First debt paid off | Debt-free after | Total interest |
|---|---|---|---|---|
| Avalanche | Card A (22.99%), Card B, line of credit | Month 25 | 32 months | $2,379.27 |
| Snowball | Line of credit ($1,500), Card B, Card A | Month 12 | 33 months | $2,723.80 |
| Minimums only ($255 a month) | No extra payment | Month 40 | 54 months | $4,198.87 |
The avalanche finishes one month sooner and costs $344.53 less in interest. The snowball, however, eliminates the line of credit after 12 months, while the avalanche's first payoff comes after 25 months. Paying only the minimums would take 54 months and cost $4,198.87.

Which method should you choose?
Choose the avalanche if your rates are far apart and you can stay patient. The gap grows when one card charges much more than the others.
Choose the snowball if you have tried before and given up, or if your balances are small and close in rate. A plan you follow beats a cheaper plan you abandon. You can also mix them: start with one quick win, then switch to the avalanche.
Pay off credit card debt faster
The method sets the order. These steps make the total smaller or the timeline shorter.
- Stop adding new charges: put the card away while you repay, or the balance will not shrink.
- Automate the payment: schedule your fixed amount right after payday so it never slips.
- Ask your issuer for a lower rate: a phone call costs nothing and some issuers say yes to good payers.
- Put windfalls on the target debt: a tax refund or a bonus can remove months from the plan.
- Check your progress monthly: watching the total fall helps you stick with the plan.
Move the balance to a lower rate
A balance transfer can stop interest for several months. As of October 18, 2026, our catalogue shows:
- CIBC Select Visa* Card: 0% for 10 months, 1% transfer fee
- Scotiabank Value® Visa* Card: 0% for 9 months, 1% transfer fee
- MBNA True Line® Mastercard®: 0% for 12 months, 3% transfer fee
Pay the transferred balance before the promotion ends, or the standard rate applies. Compare offers on our best balance transfer cards page, or a permanent low rate on our low-interest credit cards page.
Keep a small cushion
An unexpected bill often ends up on a card and undoes months of progress. Keep a small emergency fund while you repay. Our emergency fund calculator helps you size it.
Conclusion
The avalanche saves the most money, and the snowball delivers the fastest early win. In our example, the difference was $344.53 over about 2.5 years, which is real but not huge. The bigger savings come from paying more than the minimum, stopping new charges and moving balances to a lower rate when you qualify. Pick the method you will follow, automate the payment and track your progress every month.

Frequently asked questions about paying off credit card debt
Is the avalanche or snowball method better?
The avalanche method costs less because it targets the highest interest rate first. In our $8,500 example, it saved $344.53 in interest and finished one month sooner than the snowball. The snowball wins on motivation, since you pay off your smallest debt quickly. If you are likely to quit without early progress, the snowball can be the better choice for you. Run both with your own numbers using our debt payoff calculator.
How long does it take to pay off $10,000 in credit card debt?
It depends on your interest rate and your monthly payment. At a 20.99% rate, a fixed payment of $500 a month clears $10,000 in 25 months, with $2,414.56 in interest. Cut the payment to $300 a month and it takes 51 months and $5,135.24 in interest. Enter your balance, rate and payment in our debt payoff calculator to see your exact timeline and total interest.
Should I pay off credit cards or save first?
Most people should do both, in a set order. A small cushion stops new emergencies from landing on your cards. After that, extra money usually works harder against a card charging around 20% than in a savings account. Size your cushion with our emergency fund calculator, then direct the rest to your debt.
Does paying off credit card debt raise my credit score?
Lower balances usually help, because the share of available credit you use is one of the factors that affects your score. Paying on time every month also builds a positive history. Closing paid-off cards can reduce your available credit, so think before you cancel. Our guide on whether closing a credit card hurts your score explains the trade-off.
Is a balance transfer worth it?
A balance transfer is worth it if you can repay most of the balance during the promotion. Cards in our catalogue offer a 0% promotion for 9 to 12 months, as of October 18, 2026, but each charges a transfer fee on the amount moved. The FCAC notes you can lose the promotional rate if you miss a payment. See current offers on our best balance transfer credit cards page.
What if I cannot afford the minimum payments?
Call your card issuer first: some offer payment arrangements. A non-profit credit counsellor can review your budget and may propose a debt management plan, which can reduce or remove interest. If your debts are beyond that, a licensed insolvency trustee can explain your legal options. Our loans hub covers consolidation options.
