Should You Pay Off Your Student Loan or Invest First in Canada?

You graduated — or you’re close to it — and you’ve got your first real income coming in. The question is nagging you: should you throw every extra dollar at your student loans, or start building an investment account now so compound interest has more time to work? This is one of the most common money dilemmas for young Canadians, and the honest answer is: it depends on your interest rate. But there’s a clear framework that makes this decision a lot less stressful, and it’s one most financial advice completely glosses over.

Quick answer: If your student loan interest rate is higher than what you could reasonably earn investing, pay the debt first. If your rate is low (typically below 5–6%), consider splitting your extra money between both. Most government student loan interest in Canada is now 0% on federal loans — which changes the math significantly.

What interest rate is your student loan charging you?

Your loan’s interest rate is the single most important number in this decision. As of 2023, the federal government eliminated interest on Canada Student Loans and Canada Apprentice Loans — meaning if your debt is federal, you’re currently paying 0% interest. That changes the math completely. If you have a 0% federal loan, there is almost no financial argument for rushing to pay it off faster than required. Every extra dollar you put toward a zero-interest loan is a dollar not compounding inside a TFSA.

Provincial loans are different — they vary by province, and some still charge interest. If your Ontario or BC provincial loan carries a rate of 5% or higher, that’s real money leaving your pocket each year. Check your loan servicer account or your National Student Loans Service Centre (NSLSC) portal to find your exact rate. If you don’t know it off the top of your head, that’s the first thing to look up before making any plan.

How does investing compare to paying off debt?

Paying off debt with a 6% interest rate is equivalent to earning a guaranteed 6% return on your money — tax-free. That’s actually really good. The Canadian stock market has historically returned somewhere in the range of 7–10% annually on average over long periods, but that’s not guaranteed, and year-to-year swings can be significant. If your debt rate is 6% or higher, paying it off is a competitive “investment” with no risk.

If your loan rate is below 5%, investing in a diversified index fund inside your TFSA starts to look more attractive on paper — especially because gains in a TFSA are completely tax-free. A low-cost ETF tracking a broad Canadian or global index, held for decades, has historically outperformed that low interest cost. But “historically” is doing a lot of work in that sentence. Markets go down. Debt is certain. Your personal tolerance for that uncertainty matters too.

Quick tip: If you have federal student loans at 0% interest, prioritize maxing out your TFSA before making extra loan payments. The opportunity cost of not investing now is real, and you’ll never get those contribution years back.

What if you can’t afford to do both?

If your budget is tight and you’re choosing between the minimum payment and investing, always make the minimum payment first. Missing a loan payment damages your credit score and can trigger penalties — that’s a guaranteed bad outcome. Once you’ve covered minimums, any extra cash is where the decision kicks in.

A common middle-ground approach is to split your surplus: put half toward extra loan payments and half into your TFSA. This isn’t mathematically optimal in every situation, but it builds both habits simultaneously and reduces the psychological weight of carrying debt. It’s also more flexible — if your life situation changes, you can shift the balance.

One thing worth considering: TFSA contribution room accumulates whether you use it or not, but only from the year you turn 18 and become a Canadian resident. Every year you don’t use it, that room doesn’t disappear — it rolls forward. But time in the market matters for compounding, and a dollar invested at 23 is worth significantly more at 65 than a dollar invested at 30. The earlier you start, the less you have to contribute overall to reach the same outcome.

Does the type of student loan change the answer?

Government-backed Canada Student Loans and provincial loans are very different from a bank student line of credit. Many students and new grads have both — a government loan with currently 0% federal interest, and a student line of credit from their bank at prime plus 0–1%. As of 2026, the prime rate means these lines of credit are carrying somewhere around 5–6%+ interest. That’s not trivial.

If you have a bank line of credit at 5–6%, paying it down aggressively makes sense alongside moderate investing. If your debt is entirely federal government student loans at 0%, the case for prioritizing investing is strong. Most people in their mid-20s with a mix of both will do best by: paying down the high-interest line of credit first, investing consistently inside a TFSA, and making minimum payments on the low or zero-interest government loan.

Frequently Asked Questions

Should I pay off my Canada Student Loan or invest in my TFSA first?

If your Canada Student Loan is at 0% federal interest, investing in your TFSA first is often the smarter financial move. Every dollar inside your TFSA grows and can be withdrawn tax-free, and contribution room is limited and time-sensitive. The exception is if you have provincial loan balances still carrying interest — tackle those more aggressively.

What interest rate makes it worth paying off student debt before investing?

A useful rule of thumb: if your loan interest rate is consistently above 6–7%, paying off the debt first is the financially safer choice, since that matches or exceeds what you’d expect from long-term market returns. Below 5%, investing — especially inside a TFSA — typically comes out ahead over the long run, though this depends on market performance.

Can I do both at the same time?

Yes — and for many Canadians, a split approach works well. Covering your minimum loan payment while contributing even a small amount monthly to a TFSA or RRSP builds the investing habit and gives your money more time in the market. You can always increase your loan payments later if your income grows.

What if my student line of credit is at a high interest rate?

A student line of credit from a bank at 5–6%+ interest should generally be paid down before investing beyond your RRSP employer match (if you have one). High-interest debt is a guaranteed drain on your finances each month, whereas investment returns are uncertain. Pay down the line of credit aggressively, then redirect that cash flow to investing once it’s cleared.

Does paying off student loans build credit?

Yes — making consistent on-time payments on your student loan builds your credit history and improves your credit score over time. Closing the account once it’s paid off may cause a small, temporary dip (since it shortens your credit age), but that recovers quickly.
