Which debt payoff method saves more money — snowball or avalanche?

The avalanche method (highest interest rate first) always saves more money mathematically because you minimize total interest paid. However, the difference is often smaller than people expect, and the snowball method (smallest balance first) produces faster early wins that help many people stay on track. The best method is the one you actually stick with.

What interest rate do Canadian credit cards typically charge?

Most Canadian credit cards charge around 19.99% to 22.99% annual interest on purchases. Some store cards and cash advance balances are even higher. This makes credit card debt among the most expensive debt Canadians carry, which is why paying it off quickly — with either method — saves significant money.

Can I combine the snowball and avalanche methods?

Yes. A common hybrid approach is to knock out one small debt first for a motivational win (snowball), then switch to targeting the highest-interest debts (avalanche). This gives you a quick early win and then maximizes long-term savings. The exact method matters far less than making consistent extra payments on your debt.

Debt snowball vs avalanche: which pays off debt faster?

Updated July 2026 · 7 min read · Debt

The avalanche method (highest interest rate first) saves the most money mathematically. The snowball method (smallest balance first) produces faster early wins and keeps more people motivated. In practice, the best method is the one you actually follow through on — both beat making minimum payments by a wide margin.

You've decided to get serious about paying off debt. Good. Now two camps will tell you you're doing it wrong. Here is what each method actually does — with real numbers — so you can choose and stop second-guessing yourself.

The debt snowball

The snowball method was popularized by personal finance author Dave Ramsey. The logic is entirely psychological:

List all your debts from smallest balance to largest, ignoring interest rates.
Make minimum payments on every debt.
Throw every extra dollar at the smallest balance until it's gone.
When it's paid off, roll that payment into the next smallest. The "snowball" grows.

The win: you eliminate debts quickly. Crossing one off the list feels good, reinforces the habit, and frees up a payment slot that boosts your monthly cash flow early. Research has found that this psychological momentum helps more people actually finish their debt payoff.

The debt avalanche

The avalanche method is the mathematically optimal approach:

List all your debts from highest interest rate to lowest, ignoring balances.
Make minimum payments on every debt.
Throw every extra dollar at the highest-rate debt until it's gone.
Roll that payment into the next highest-rate debt.

The win: you pay less total interest over time. Since you're attacking the debt that's growing fastest, you stop the bleeding sooner. For Canadians carrying credit card debt at ~20% annually, this can mean hundreds or thousands of dollars in savings versus the snowball.

A worked example

Say you have three debts and $400/month to put toward them after minimums:

Debt	Balance	Rate	Minimum
Credit card A	$800	19.99%	$25
Credit card B	$3,200	22.99%	$70
Personal loan	$6,000	9.9%	$130

Total minimums: $225/month. Extra available: $175/month.

Snowball order

Target order: Credit card A ($800) → Credit card B ($3,200) → Personal loan ($6,000).

You clear Credit card A in about 4 months. That payment rolls into Credit card B, and so on. The early win on Card A feels great and builds momentum.

Avalanche order

Target order: Credit card B (22.99%) → Credit card A (19.99%) → Personal loan (9.9%).

You start by hammering Card B, which costs you the most per dollar owed. Card A takes longer to disappear, but you pay materially less interest over the life of the plan.

The bottom line on the numbers

With debts carrying these kinds of rates, the avalanche typically saves $200–$500 in interest compared to the snowball over a 2–3 year payoff. The exact savings depend on your balances and how long payoff takes. For most Canadians, the avalanche wins on cost — but only if you stick with it.

Canadian context: credit cards at ~20%

Most Canadian credit cards charge 19.99% to 22.99% annual interest on purchases (and higher on cash advances). At those rates, carrying a $3,000 balance costs you roughly $600 in interest per year while you're making minimum payments. The math heavily favours attacking high-rate credit card debt first — which in most cases aligns with the avalanche method.

If you have a mix of high-rate credit card debt and lower-rate student loans or car loans, the avalanche will direct your extra payments to the right place automatically.

When the snowball makes sense

Your debts have similar interest rates and the math difference is small.
You have many small balances cluttering your finances and you want to simplify.
You know yourself: past attempts at debt payoff have stalled, and you need early wins to stay motivated.
One small debt is causing stress disproportionate to its size.

When the avalanche makes sense

You have one very high-rate debt (a 22%+ credit card) that dwarfs the others.
You are disciplined and numbers-driven — the psychological wins from the snowball don't matter as much to you as the final interest bill.
Your debt payoff timeline is long (3+ years) and the interest savings are substantial.

The hybrid approach

Many Canadians find success with a hybrid: knock out your one smallest debt first for a quick win, then switch to avalanche order for everything else. This gives you the motivational boost of the snowball without sacrificing much on the math. If your smallest debt takes only a month or two to clear, the total interest cost of the "detour" is minimal.

What both methods agree on

Regardless of which approach you choose, the fundamentals are the same:

Pay more than the minimum. Minimum payments on Canadian credit cards are designed to keep you in debt for years.
Stop adding to the debt. The method only works if you stop charging more than you can pay off monthly. Consider temporarily freezing discretionary credit card use.
Automate your extra payment. Set a recurring transfer on payday so the money moves before you can spend it.
Don't take on new high-rate debt while you're paying off the existing pile.

The math only works if you find the money to throw at the debt

Whether you choose snowball or avalanche, the question becomes: where does the extra payment come from? Looni is being built to find the leaks in your spending — fees, subscriptions, and junk charges you've stopped noticing — and show you exactly what to redirect. Canadian-built, launching soon.
