Personal Loan or Personal Line of Credit: Closed-End Certainty vs Revolving Flexibility

A personal loan gives you a fixed sum, repaid on a schedule you can see in advance, and it ends on a date you know before you sign. A personal line of credit gives you a limit you can draw from, repay, and draw from again, so it continues to exist until you deliberately close it. The choice between a personal loan or personal line of credit is therefore not really about interest rates first — it is about whether you want the lender to impose an end date, or whether you are prepared to impose one on yourself.

What you are actually choosing between

Both products are forms of consumer borrowing, and the Financial Consumer Agency of Canada describes the cost of any loan as a function of the amount borrowed, the rate applied to it, and the time the balance stays outstanding. Two products with the same rate can cost very different amounts because of that third variable. The structural difference between them is what drives it.

Closed-end: the personal loan

A personal loan is an instalment loan. The lender advances the full amount once, and you repay it in scheduled payments over an agreed term. Interest is charged on the outstanding balance, and because that balance is forced downward on a set schedule, the loan has a known end date and a total cost you can estimate before you commit. What you give up is flexibility: once the money is advanced, you owe the full amount whether or not you still need it, and whether or not your income changes. Some contracts permit extra payments or early payoff, and others attach conditions or costs to doing so. Those terms deserve more attention than the advertised rate.

Revolving: the personal line of credit

A personal line of credit is an open-end arrangement. The lender approves a limit; you draw what you need, when you need it, and interest is charged only on the portion currently drawn. Every payment restores room to borrow again, which is genuinely useful when a cost is unpredictable. Payments on a line of credit are typically calculated as interest plus some required portion of principal, though the mechanics vary by contract and lender. Lines of credit are frequently priced off a variable benchmark, which means the cost of carrying the balance moves when that benchmark moves — and it can move against you.

The trap is not the product itself. It is the open end. Nothing inside the structure forces the balance to zero.

How each one costs you money

Interest is charged on a balance for as long as that balance exists. That single sentence explains most of the practical difference between the two.

• With a loan, the balance starts at its highest point and is pushed down by the payment schedule. You pay more interest early and less later, but the finish line is fixed and visible.
• With a line of credit, you pay interest only on what is drawn — a real saving if you repay quickly. If you do not, you pay interest on essentially the same balance for as long as you leave it there.

This is why a line of credit with a lower stated rate can end up costing more than a loan with a higher one. The rate is one input; time is the other. A lower rate applied to a balance that sits for years can lose to a higher rate applied to a balance that disappears on schedule. Comparing the two products on rate alone is the most common mistake borrowers make, and it is the one that is hardest to undo after the fact.

Side-by-side comparison

Feature	Personal loan	Personal line of credit
Structure	Closed-end: the full amount is advanced once	Open-end: you draw, repay and re-draw up to a limit
Interest charged on	The outstanding balance, reduced on a schedule	Only the amount currently drawn
Payment pattern	Set amounts at set intervals for a set term	Varies with the balance and the rate
Rate type	Fixed or variable, depending on the contract	Usually variable, tied to a benchmark
Certainty of end date	Known at the outset	None, unless you create one
After you repay	You must apply again to borrow more	Available room returns automatically
Main risk	Committed to payments if your circumstances change	A balance can remain drawn quietly and indefinitely
Generally suited to	A defined one-time cost, or forcing a payoff	Uneven income, or short gaps you clear quickly

The discipline question

Flexibility is only worth paying for if you use it in both directions — drawing when needed, and repaying with intent. A line of credit asks you to make the amortization decision yourself, on every payment, forever. A loan makes that decision once, in a document, before you have the money in hand.

The most common way people get hurt is converting debt rather than repaying it. Moving amortizing balances onto a line of credit can feel like progress because the payment drops, but if the balance now revolves, the debt has not been rescheduled — it has merely been made more comfortable. The payment fell because you stopped repaying principal at the same pace.

A blunt way to sort yourself: if you already know that a drawn balance tends to stay drawn for you, a closed-end loan is usually the cheaper form of self-control. You are paying a small premium for a structure that removes a choice you would otherwise make badly. If your income is genuinely irregular — self-employed, commission-based, seasonal — a line of credit solves a real problem that a loan cannot, and the discipline question becomes a budgeting question instead.

Where each product tends to fit

• Favour a loan when the amount is known, the timing is known, and you want a scheduled payoff you cannot renegotiate by accident.
• Favour a loan when you are consolidating balances and the goal is to stop them from revolving.
• Favour a line of credit when the amount is genuinely uncertain, the timing is unpredictable, or the money is a standby reserve you may not draw at all.
• Favour a line of credit when you want to borrow, repay within a short window, and preserve access later without reapplying.

Regulation, rates and your rights

Federal law puts an outer boundary on what can be charged. The Criminal Code criminal rate of interest is 35% per year under section 347, calculated using a defined method that aggregates interest and certain charges, as the Financial Consumer Agency of Canada explains. Most lenders that are not federally regulated are licensed and supervised by their province, and each province has a consumer protection office; complaints about federally regulated financial institutions are handled by the Financial Consumer Agency of Canada. Knowing which regulator applies to the lender you are dealing with is useful if something goes wrong.

Payday-style credit sits in a separate regime. Where a province operates a licensed payday lending regime, federal payday lending regulations (SOR/2024-114) cap the cost of borrowing at $14 per $100 advanced, and where a province sets a lower cap, the lower figure applies. Quebec does not license payday lending, which effectively prohibits the model there. These loans are generally up to $1,500 for a term of 62 days or less — a structure built for a single short repayment, not for the long amortization a personal loan is designed around. If you are considering that route, be clear about what you are buying: speed and accessibility, not inexpensive credit.

Secured versus unsecured

Either product can be secured or unsecured, and the difference matters more than the label. Federal rules set the ceiling on secured borrowing: at federally regulated lenders, home equity lines of credit are generally limited to 65% of appraised property value, with total secured lending usually capped at 80%. Federally regulated mortgage lenders also generally work to a total debt service ratio ceiling of about 44% under Guideline B-20, applying a qualifying stress-test rate above the contract rate. Those figures decide whether the debt fits on paper, but the practical point is simpler: a secured line of credit puts an asset behind the balance. Unsecured credit does not carry that risk, and the lender prices its own risk accordingly.

If your credit history is the real obstacle

Canada has two national credit reporting bureaus, Equifax Canada and TransUnion Canada, and a free copy of your credit report is available from each — the fastest way to see roughly what a lender sees before you apply. Negative history has a defined lifespan: a consumer proposal stays on a credit report for three years after completion, or six years from filing, whichever comes first, and a first bankruptcy stays on for six years after discharge. Only a licensed insolvency trustee can administer a consumer proposal or bankruptcy, and trustees are regulated by the Office of the Superintendent of Bankruptcy Canada. Whether to restructure debt formally, consolidate it, or simply wait and rebuild is a decision that depends on your individual circumstances, and it is significant enough to bring to a regulated professional rather than settle from a comparison page.

How to decide, step by step

1. Write down the purpose and whether the amount is fixed. A known cost with a known deadline is describing a loan. A genuinely unknown amount is describing a line of credit.
2. Write down what your own minimum payment would be, then ask whether you would pay more than it. A line of credit only works if the honest answer is yes.
3. Compare total cost, not the headline rate. For the loan, the schedule gives you the number. For the line of credit, estimate how long the balance would realistically sit there — then be pessimistic about your own estimate.
4. Check whether the credit is secured. Understand exactly which asset stands behind the balance, and what happens if you cannot pay.
5. Read the prepayment terms, the fee schedule, and how the rate is set. Ask specifically what happens if a variable benchmark rises: does the payment change, or does the term stretch?
6. Get the disclosure in writing before you sign, and keep it. A verbal explanation of how the payment is calculated is not the contract.

loanloon.ca is a matching and comparison service, not a lender. It does not make loans, set rates or make credit decisions; any loan or line of credit you are offered comes from a lender that applies its own criteria. The lowest rates are only available to the most qualified applicants, and qualification depends on income, existing debts, credit history and the lender's own underwriting. If your situation involves insolvency, a consumer proposal, or a secured debt that puts a home at risk, treat the comparison as a starting point and get advice from a regulated professional before you commit.
