Both methods pay off your cards in the same amount of time. On a typical three-card mix totalling $8,100, the avalanche costs $1,140 in interest and the snowball costs $1,277, a difference of about $137. Both clear in 1 year 7 months. The real gap is between having either plan and having none: paying minimums only on the same debt takes over 20 years and costs $9,222 in interest. This guide breaks down both methods with real numbers, shows when each one is the better choice, and links to a free calculator where you can run your own cards.
Key Takeaways
- The avalanche method (highest rate first) always costs the least in total interest. On the $8,100 example from the NotchUp payoff calculator, it saves $137 compared to the snowball.
- The snowball method (smallest balance first) clears cards sooner, giving you fewer statements, fewer due dates, and visible progress that keeps you going.
- Both methods clear the same $8,100 in 1 year 7 months. The payoff date is typically identical because both send the same total payment at the same total debt.
- Having any plan at all saves $8,082 and nearly 19 years compared to paying minimums only. The choice between methods is worth roughly 1.5% of the choice to have a plan.
- The free payoff calculator models avalanche, snowball, and minimums-only side by side on your own cards, including the month each card clears.

Key Takeaway
On a typical three-card mix the choice between avalanche and snowball is worth about $136; the choice to have a plan at all instead of paying minimums is worth over $8,000 and 18 years.
How the Avalanche Works
Pay the minimum on every card. Then send everything you have left over to the card with the highest interest rate, regardless of its balance. When that card hits zero, its minimum and the extra both roll onto the next highest rate. Repeat until nothing is left.
Take the calculator’s example: $8,100 spread across a Visa, a store card, and a line of credit. Run as an avalanche, it clears in 1 year 7 months and costs $1,140 in interest. Because the most expensive debt is attacked first, the avalanche always costs the least in total. That is arithmetic, not a personality type.
The weakness is what it feels like from the inside. If your highest-rate card is also your biggest balance, you can pay hard for six months and still have three cards, three statements, and three due dates. Nothing visibly changes. That is the stretch where people quit, and a plan abandoned in month five costs more than a plan finished in month nineteen.
How the Snowball Works
Same first step: pay every minimum. Then send everything spare to the card with the smallest balance, ignoring its rate. When that card is gone, its minimum payment is freed up and joins the extra, which now goes at the next smallest balance. Each cleared card makes the payment hitting the next one bigger.
On the same $8,100, the snowball also clears in 1 year 7 months and costs $1,277 in interest. It costs more because some of your money spent a few months on a cheap balance while an expensive one kept compounding. How much more is the number that should decide this, and it is usually smaller than people expect. What you get in exchange is cards disappearing, which for a lot of people is the difference between a plan and a wish.
The Gap Is Smaller Than You Think
All three approaches on the same $8,100, with the same monthly payment going in each time. “Minimums only” means paying exactly what the statement asks for and nothing more.
| Method | Time to clear | Interest paid |
|---|---|---|
| Avalanche | 1 year 7 months | $1,140 |
| Snowball | 1 year 7 months | $1,277 |
| Minimums only | 20 years 5 months | $9,222 |
Read the table from the bottom up. Having any plan saves $8,082 and 18 years 10 months. Choosing between the two plans is worth $136.56. The choice everyone argues about is roughly one and a half percent of the choice nobody argues about.
The gap is small for a boring reason. Both methods put the same money against the same total debt every month. Only the order changes, and order only matters in the months where the two plans are working on different cards. Here the store card clears in month 4 under both methods, the Visa in month 14, the line of credit in month 19. The payoff calculator shows the month each card clears for your own mix.
Run it on your own cards
The gap on your cards will not be $136.56. It depends on your balances, your rates and what you can pay a month. The free NotchUp payoff calculator models the shrinking minimum properly and shows all three approaches side by side, including the month each card clears.
When the Snowball Is the Right Answer
Pick the snowball when you know yourself well enough to admit you need to see something happen. If a card at zero in month 4 is what keeps you paying in month 5, $137 is the cheapest motivation you will ever buy. Nobody hands out prizes for the optimal plan you gave up on.
It also has a practical edge the interest figure hides. Every cleared card frees its minimum payment and removes one statement, one due date, and one chance to miss a payment. A late payment mark on your credit file costs more than $137 in ways that take years to fade.
The snowball makes the most sense when your highest-rate card is also your biggest balance. That is the setup where the avalanche feels like shouting into a well for a year. Clearing the small cards first costs a little extra, but you arrive at the big one with a larger monthly payment and fewer things to think about.
When the Avalanche Is the Right Answer
Pick the avalanche when the rate gap between your cards is large. Canadian cards cover a wide range: a low-rate card at 12.99%, a standard card at 19.99%, a rewards card at 22.99%, a store card at 29.99%. If you are carrying a 29.99% store card alongside a 12.99% low-rate card, every dollar on the store card costs more than double. Paying the cheap card first because it is smaller means feeding the expensive one for months, and here the gap between methods stops being pocket change.
It is also the right call when the highest-rate card happens to be the smallest, because then both methods point at the same card and the argument is over before it starts. And if you get more satisfaction from a spreadsheet than from a cut-up card, you already know which one you are choosing.
Two Things That Matter More Than the Method
1. How much you pay above the minimums. This is the whole game. Minimums are a percentage of the balance, so they shrink as you pay, which is exactly why minimums-only stretches for decades. Take one card with $5,000 at 19.99%. The first minimum is about $150 (at a typical 3% rate), which sounds like progress. Pay only the minimum and the card takes roughly 20 years to clear and costs close to $6,000 in interest, more than you borrowed.
Outside Quebec there is no legislated minimum; issuers typically ask for 2% to 3% of the balance or $10, whichever is greater, and your cardholder agreement gives the exact figure. Whatever it is, the amount you send above it decides your payoff date far more than the order you pay in. An extra $50 a month is worth more than any method. If money is tight, there is a separate guide on getting out of debt on a low income in Canada.
2. Not adding new charges, and keeping cleared cards open. A payoff plan only works if the balances move in one direction. Put the cards somewhere inconvenient if you have to. And when a card hits zero, do not close it.
Closing a card removes its limit from your file, which raises your utilization, the share of your available credit you are using. Utilization is one of the two most important inputs to a Canadian credit score alongside payment history. It is scored on a continuum, so there is no cliff at 30% where you are suddenly safe, and it is reported on your statement date, not your due date. A cleared card left open at zero quietly helps your score every month. More in the guide to credit score ranges in Canada.
A Quebec Note
Quebec is the one province with a legislated minimum. Since August 1, 2025, it has been 5% of the balance, the end of a gradual phase-in that raised it from 2% starting in 2019 (cards opened after August 2019 started at 5% immediately). The same $5,000 at 19.99% takes about 10 years and costs $2,443 at the Quebec minimum, compared to roughly 20 years and close to $6,000 elsewhere at a typical 3% minimum. That changes the baseline. It does not change the choice: the avalanche still costs the least, the snowball still clears cards sooner, and the gap between them is still a fraction of what any plan saves over the floor.
Frequently Asked Questions
Is avalanche or snowball faster?
Usually neither, by any margin you would notice. Both send the same total payment at the same total debt, so the final payoff date is typically identical or a month apart. In the $8,100 example, both clear in 1 year 7 months. What differs is the order the cards vanish in and the interest paid along the way.
How much more does the snowball cost?
On the three-debt example, $136.56 over the life of the payoff. On your cards it could be less, or a good deal more if a 29.99% store card sits next to a low-rate card. Rather than guess, put your balances, rates, and monthly payment into the payoff calculator and read the difference off the results.
Should I close a credit card after paying it off?
Generally no. Closing it removes its limit, which raises your utilization and can lower your score. Keep it open at zero, and if you do not trust yourself with it, leave it in a drawer. The exception is a card with an annual fee you no longer want; even then, ask the issuer about a no-fee version first.
What if I can only pay the minimums?
Then the method question does not apply yet, because both need something above the minimum to work with. The priority is finding any extra at all, even $20 a month, and pointing it at one card. A fixed extra payment beats a shrinking minimum because it does not get smaller as the balance falls. If the problem is timing rather than total income, a pay advance can bridge the gap between when the bill is due and when your paycheque arrives.
Does it matter which card I pay first if the rates are the same?
Not to the interest total. With equal rates the avalanche has no opinion, so clear the smallest balance first. You get the motivational win and the freed-up minimum for free, and the math is indifferent.
Can I use avalanche or snowball on debts other than credit cards?
Yes. Both methods work on any mix of debts with fixed minimum payments: credit cards, personal loans, lines of credit, car loans. The logic is the same. The payoff calculator accepts different debt types alongside credit cards.
What is the minimum payment on a credit card in Canada?
Outside Quebec, there is no legislated minimum. Issuers typically set it at 2% to 3% of the outstanding balance or $10, whichever is greater. Your cardholder agreement specifies your exact formula. In Quebec, the legislated minimum is 5% of the balance since August 1, 2025.
Does paying off credit card debt improve my credit score?
Yes, primarily through utilization. As your balances drop, your credit utilization ratio improves, which is one of the two most important factors in a Canadian credit score alongside payment history. The improvement shows up within one to two statement cycles. Keeping the cleared cards open (rather than closing them) preserves the benefit because the available credit stays on your file.
