Should You Save or Pay Down Debt First in Canada? 2025

Updated March 2025 · 8 min read

This is one of the most common money questions young Canadians ask, and the honest answer is: it depends on the interest rate. Not on your feelings about debt. Not on what your parents think. On the interest rate.

Here's a framework for making this decision rationally, with specific guidance for the types of debt most young Canadians carry.

The Core Math

Every debt has a cost: its interest rate. Every investment has an expected return. The decision is essentially: does my expected investment return exceed my debt's cost?

• Credit card debt at 19.99%: Pay it off. No investment gives you a guaranteed 20% return. Paying off 20% debt IS a guaranteed 20% return.
• Car loan at 7%: The market beats 7% on average historically, but not guaranteed in any given year. Generally: pay it down while also investing some.
• Student loans (federal) at 0%: Invest in your TFSA. There's zero cost to carrying this debt.
• Mortgage at 4-6%: Split strategy — some extra payments, some investing. Both are reasonable.

Debt Priority Order for Young Canadians

1. Build small emergency fund first ($1,000-$2,000). Non-negotiable. Without this, one unexpected expense sends you back into debt.
2. Capture employer RRSP match. It's a 50-100% immediate guaranteed return. Nothing beats this.
3. Pay off high-interest consumer debt (credit cards, payday loans, personal loans above 8%)
4. Build full emergency fund (1-3 months of expenses)
5. Invest in TFSA (index ETFs, good expected return)
6. Pay down lower-interest debt (student loans at 0-4%, low-rate car loans)
7. Maximize RRSP once in a meaningful tax bracket

The Emergency Fund Exception

Some people argue you should pay down all debt before building savings. This is wrong for a simple reason: without a cash buffer, any unexpected expense goes onto a credit card at 19.99%. You're paying down debt only to immediately re-accumulate it.

Build your emergency fund first — in a high-interest savings account TFSA so it earns something while it sits — before aggressively attacking debt below 10%.

When to Choose Saving/Investing Over Debt Payoff

Investing beats debt payoff when:

• You have employer RRSP matching available (always take it)
• The debt carries 0% or very low interest (federal student loans, some car promos)
• You have significant TFSA room — the tax shelter benefits of compound growth inside a TFSA are real and increase the math in favor of investing
• You're young — time is your biggest investing asset, and the earlier you start, the more compound growth compounds

The Emotional Argument for Debt Payoff

There's a real psychological argument for paying down debt aggressively even when the math doesn't strictly demand it. Being debt-free feels good. It reduces financial anxiety. It improves sleep. It makes you more financially resilient to job loss or income disruption.

The Dave Ramsey "debt snowball" approach — paying off smallest balances first regardless of interest rate — is mathematically suboptimal but psychologically effective for many people. If you're the type who needs wins to stay motivated, the snowball's momentum can be worth the math cost.

Personal finance is personal. A plan you'll stick to beats an optimal plan you'll abandon.

The Split Approach: Having It Both Ways

For medium-rate debt (3-7%), many Canadians do both simultaneously:

• Automate minimum debt payments
• Automate TFSA contributions
• Direct any surplus income toward whichever you're more focused on that month

This approach builds investment wealth while making progress on debt, without forcing an all-or-nothing choice. It's not mathematically perfect but it's practical and sustainable.

A Note on FOMO-Driven Investing

Seeing markets go up while you're sitting with cash paying off debt can feel agonizing. Resist the urge to invest in speculative assets (individual stocks, crypto, options) with money that should be going toward high-interest debt. The expected return of those investments doesn't justify the guaranteed 20% cost of leaving credit card debt unpaid.
