Student Loan Repayment Strategies in Canada: Avalanche vs Snowball

You’ve landed your first real job, you’re getting used to seeing actual deposits in your chequing account, and somewhere in the back of your mind sits a number you’d rather not think about - your student loan balance. Whether you borrowed from the Canada Student Loan Program, your provincial government, or both, the average Canadian graduate leaves school owing somewhere between $20,000 and $28,000 CAD. The good news? You have more control over how fast that number shrinks than you might think. Two of the most popular payoff strategies - the avalanche method and the snowball method - can both get you to zero, but they work differently, feel different, and suit different people. This post breaks down exactly how each one works, which one saves you more money, and how to figure out which fits your life right now.

What Is the Avalanche Method?

The avalanche method means you put every extra dollar toward the loan with the highest interest rate first, while making minimum payments on everything else. Once that top-rate loan is gone, you roll its payment into the next highest-rate loan, and so on.

Here’s why it works so well mathematically: interest is the cost of carrying debt. The higher the rate, the faster your balance grows. By eliminating high-rate loans first, you stop the most expensive bleeding as quickly as possible.

Canadian example: Say you have three loans:

• $12,000 CAD provincial student loan at 9.5% interest
• $8,000 CAD Canada Student Loan (federal, prime + 1%, roughly 6.2% in 2025)
• $4,000 CAD line of credit at 5.5%

With the avalanche method, you’d attack the 9.5% provincial loan first. If you throw an extra $300/month at it on top of minimums, you’ll clear it faster and pay significantly less total interest over the life of your loans compared to tackling the smaller balances first.

The trade-off: it can feel slow. If your highest-rate loan is also your biggest balance, it might be months before you see a balance hit zero - and that can be psychologically brutal.

What Is the Snowball Method?

The snowball method flips the logic. Instead of targeting the highest interest rate, you focus on the smallest balance first, regardless of the rate. You make minimum payments on everything else and throw all your extra cash at the tiniest loan until it’s gone. Then you take that payment and roll it into the next smallest loan - hence the snowball.

The payoff here is psychological. Clearing a balance completely - even a small one - triggers a real sense of momentum. Research in behavioural finance consistently shows that people who use the snowball method are more likely to stick with their repayment plan long-term, precisely because of those early wins.

Canadian example: Using the same three loans from above, you’d target the $4,000 line of credit first. Wipe that out, then move to the $8,000 federal loan, then the $12,000 provincial loan. You’ll pay more in total interest over time, but you’ll have two accounts closed before you’d have closed one under the avalanche approach.

Quick tip: If your smallest loan also happens to have the highest interest rate, both methods point to the same loan - so just start there and enjoy the best of both worlds.

Avalanche vs Snowball: Which Saves More Money?

The avalanche method almost always wins on pure numbers. Prioritising high-interest debt reduces the total amount of interest you pay over the repayment period. Depending on your loan balances and rates, this difference could easily add up to $500–$2,000 CAD or more over a five-to-seven year repayment window.

That said, “saves the most money” only matters if you actually follow through. If the snowball method keeps you consistent and motivated while the avalanche has you feeling stuck and tempted to pause extra payments, the snowball wins in practice - even if it loses on paper.

A useful rule of thumb: if your interest rates are all within a few percentage points of each other, the financial difference between the two methods is small. Go with snowball for the motivation boost. If you have one loan charging significantly more than the others - like a private loan or a provincial loan with a high variable rate - the avalanche makes more sense.

How Canada-Specific Rules Affect Your Strategy

A few things unique to Canadian borrowers are worth factoring in before you pick your approach.

Federal loan interest: As of 2023, the federal government eliminated interest on Canada Student Loans permanently. That changes the math significantly - your federal loan is now essentially a 0% debt, which means under the avalanche method, it goes last. Your provincial loans and any private debt jump to the front of the line.

Repayment Assistance Plan (RAP): If your income is low, you may qualify for RAP through the National Student Loans Service Centre (NSLSC), which caps your payments as a percentage of income. If you’re enrolled in RAP, your strategy may look different - focus extra payments on higher-rate provincial or private debt while RAP handles your federal minimums.

Tax deduction: Historically, student loan interest was deductible on your CRA tax return. With federal loans now at 0%, this applies mainly to provincial loan interest. Keep records and check your Notice of Assessment each year - every dollar counts when you’re starting out.

Frequently Asked Questions

Which student loan repayment method is better in Canada - avalanche or snowball?

The avalanche method saves more money overall because it targets high-interest debt first, reducing the total interest you pay. However, the snowball method works better for people who need motivational wins to stay consistent. The right choice depends on your personality and how spread out your interest rates are.

Do Canadian federal student loans still charge interest?

No. As of April 1, 2023, the federal government permanently eliminated interest on Canada Student Loans. This means your federal loan balance no longer grows, and under an avalanche strategy, it effectively becomes your last priority - focus extra payments on higher-rate provincial or private loans first.

Can I make extra payments on my Canada Student Loan without a penalty?

Yes. There are no prepayment penalties on Canada Student Loans. You can increase your regular payments or make lump-sum payments at any time through the NSLSC portal. Even small extra amounts - like an extra $50–$100 CAD per month - can meaningfully shorten your repayment timeline.

What is the Repayment Assistance Plan (RAP) in Canada?

The Repayment Assistance Plan (RAP) is a federal program that reduces your student loan payments if your income is below a certain threshold. Payments are capped at a percentage of your gross income, and in some cases you may pay nothing at all. You need to apply and reapply every six months through the NSLSC.

Should I pay off student loans or invest while I’m in my 20s?

It depends on the interest rate. If your loan rate is higher than what you’d reasonably earn investing (roughly 5–7% annually), prioritise the debt. If your rate is low - especially with federal loans now at 0% - it can make sense to contribute to a TFSA or FHSA at the same time, since those accounts offer tax-sheltered growth that compounds over decades.
