Good Debt, Bad Debt, and How to Manage What You Owe as a Student

The average Canadian carries $21,931 in non-mortgage debt. Most of them were never taught what separates the debt that is manageable from the kind that quietly drains you for years.

"Debt" is one of those words used to describe wildly different situations. A federal student loan and a payday loan both count. They have almost nothing in common. One costs you nothing right now and helped fund something that can raise your income for the rest of your working life. The other carries an effective annual interest rate that can exceed 300%.

As a student, you are probably already carrying some form of debt, or you will be soon: a student loan, a line of credit, a credit card you opened to start building your history. The question is not whether to have debt. It is whether the debt you have is working for you or against you.

The real framework is not good versus bad. It is rate versus return: does what you borrowed for generate more value than the interest it costs you? And just as importantly, do you have a plan to pay it off before it compounds against you?

The Good vs. Bad Debt Framework (And Where It Falls Short)

The traditional breakdown goes like this. Good debt builds assets or earning potential over time: a mortgage, a student loan, a business loan. Bad debt buys things that lose value with no financial upside: a credit card balance you roll month to month, a payday loan, store financing for a TV.

It is a useful shortcut. It also breaks down fast.

A student loan for a program with weak job market outcomes is not automatically good debt because education is an investment. A credit card used for groceries and paid in full every month is not bad debt, it is a free short-term loan with rewards on top. The category matters less than the specifics.

The better question before taking on any debt: what is the interest rate, and what do I actually get in return? A 0% federal student loan funding a degree that raises your income by $24,000 a year is a completely different situation from a 29.99% store card used to buy a laptop. Same word. Different universe.

The Debt Students in Canada Actually Deal With

Here is a quick inventory of what Canadian students are realistically carrying.

Federal student loans (NSLSC)

Federal student loans have been interest-free since the 2023 federal budget. The government covers your interest while you are in school and during the six-month non-repayment period after graduation. This is the least expensive debt most students will ever carry. If you have it, it belongs at the bottom of your repayment priority list.

Provincial student loans

Provincial loan terms vary significantly. OSAP in Ontario, StudentAid BC, Alberta Student Aid; each has its own interest structure. Do not assume federal rules apply to your provincial portion. Check your province directly before making repayment decisions.

Student lines of credit

The major Canadian banks offer lines of credit specifically for students, typically at prime rate or prime plus a small margin. Unlike student loans, interest starts accruing immediately on whatever you draw. The flexibility is real, but so is the cost if you are not tracking what you borrow and why.

Credit cards

The most common form of debt for students, and the most dangerous when mismanaged. Standard Canadian credit card interest sits between 19.99% and 20.99% for most major bank cards. Carrying a $1,000 balance month to month costs you roughly $200 a year in interest alone, for stuff you already own. That number climbs fast if the balance grows.

How Debt Affects Your Credit Score

This is the section most debt articles skip over, which is frustrating, because it is the part that actually shapes your financial life as a student and well beyond it.

Your debt is not just a number you owe. It is a data point that lenders, landlords, and eventually mortgage providers use to evaluate you. In Canada, your credit score is calculated by Equifax and TransUnion based on several key factors, and debt is woven through nearly all of them.

Credit utilization

Utilization is the percentage of your available credit you are currently using. If your credit card has a $1,000 limit and you are carrying a $600 balance, your utilization is 60%. Most credit professionals recommend staying below 30%. High utilization signals to lenders that you are stretched thin, even if you are making every payment on time.

There is a practical fix most people miss: if you have a $500 limit student card and regularly spend $400 on it, your utilization is hurting your score even if you pay the full balance every month. Requesting a credit limit increase, without increasing your spending, is one of the simplest ways to improve this ratio.

Payment history

This is the single biggest factor in your credit score, and the one with the most lasting damage when it goes wrong. One missed payment on a credit card can cause a meaningful drop in your score and stays on your Canadian credit report for up to six years. Not six months. Six years.

Set up automatic minimum payments on every account. You can always pay more manually, but missing a payment because life got busy is an expensive mistake that follows you far longer than it should.

Instalment debt vs. revolving debt

Student loans and lines of credit are instalment debt: fixed repayment schedules that demonstrate you can manage a long-term financial obligation. Credit cards are revolving debt: flexible limits that reset as you pay them down. Both affect your credit differently. Making consistent on-time payments on a student loan actively builds your credit history, showing lenders you can handle a multi-year commitment without slipping.

Used responsibly, debt is one of the fastest ways to establish a credit profile as a student. Mismanaged, it is one of the fastest ways to damage one that took years to build.

The Ones That Are Just Bad

Some debt is context-dependent. These are not.

Credit card interest

Standard Canadian credit card rates sit between 19.99% and 20.99%. If you are carrying a balance month to month, you are paying roughly one-fifth of your outstanding balance in interest every year, on top of whatever you originally spent. A $3,000 balance costs around $600 annually in interest, for purchases you already made and already used.

The credit card itself is not the problem. The balance you do not pay off is.

Payday loans

Payday loans are short-term, high-cost loans designed to bridge gaps between paycheques. In Ontario, lenders can legally charge up to $14 per $100 borrowed. That sounds like 14%. It is not. Stretched across a year, the effective annual rate lands well above 300%.

These products are legal, aggressively marketed near campuses and transit stops, and structurally designed to encourage repeat borrowing. One payday loan is often the start of a cycle, not a one-time solution. If you are in a cash crunch, a student line of credit, a credit card cash advance (still expensive, but far cheaper), or a short-term loan from family all cost less. Avoid payday lenders entirely.

Deferred-interest store financing

"0% financing for 12 months" sounds like a good deal. It often is not. If you do not clear the full balance before the promotional period ends, the interest for the entire period gets added to your balance retroactively. That $800 laptop suddenly has $160 in interest attached because you were $50 short in month 12.

These deals are common at electronics and furniture retailers. The promotional period is a hard deadline. Treat it like one, or do not take the financing.

How to Pay It Off: A Practical Framework

Most students are not carrying one type of debt. They are carrying a mix: a student loan, a credit card balance, maybe a line of credit. The order you pay them down matters more than the total amount you throw at debt in a given month.

The avalanche method

Pay the minimum on every debt, then direct every extra dollar toward the highest-interest debt first. Once that is cleared, move to the next highest rate. Repeat until everything is gone.

This is mathematically optimal. It minimises the total interest you pay across all your debts and gets you out faster than any other approach. It is the right call if you can stay motivated without needing frequent visible wins.

The snowball method

Pay the minimum on everything, then attack the smallest balance first regardless of the interest rate. Once it is gone, roll that freed-up payment into the next smallest balance.

Less efficient mathematically, but the momentum from fully clearing individual debts keeps a lot of people on track who would otherwise lose steam. Pick the method you will actually follow through on. A slightly suboptimal strategy you stick with beats a perfect one you abandon by month three.

A real example

Say you are carrying three debts:

• $400 on a store card at 29.99%
• $3,000 on a credit card at 20.99%
• $15,000 federal student loan at 0%

Avalanche order: store card first (29.99%), then the credit card (20.99%), then the student loan (0%). In this case, the snowball method produces the same order, since the highest-rate debt also happens to be the smallest balance. The student loan costs you nothing right now. The other two are actively bleeding you every month. Do not let the size of the student loan distract you from the debts that are actually costing you money.

On investing while carrying debt

If you have high-interest debt, contributing to your TFSA at the same time is usually the wrong move. Paying off a 21% credit card balance is a guaranteed 21% return on that money. A diversified ETF portfolio has returned roughly 8% to 10% annually over the long run historically. The credit card math is not close.

The exception is a federal student loan at 0%. There is no cost urgency to carrying it slowly while building your TFSA, and the long-term compounding on investments can justify splitting your focus. But the moment a debt carries a meaningful interest rate, that changes.

TL;DR

• The good vs. bad debt label is a starting point, not the full picture. What actually matters is whether the cost of borrowing is lower than the value it generates for you.
• Federal student loans are currently interest-free, the cheapest debt most students will ever carry. Provincial loan terms vary, so verify yours.
• Standard Canadian credit card rates sit at 19.99%–20.99%. Carrying a balance month to month is expensive fast.
• Your debt directly affects your credit score through two main channels: your payment history and your credit utilization ratio. Both matter more than most students realise.
• If you have multiple debts, pay off the highest-interest rate first (avalanche method). That is almost always credit cards and store cards before student loans.
• Carrying high-interest debt while investing is usually the wrong trade. Paying off a 21% debt is a guaranteed 21% return. An ETF gives you maybe 8–10% historically.
• Payday loans and deferred-interest store financing are not emergency tools. They are expensive products designed to be used repeatedly. Avoid them.
