Line of Credit vs Credit Card: the Numbers Compared
You have $10,000 in debt on a 20% card and your bank offers you a line of credit. Smart move or trap? The answer comes down to one number: the rate. And between a card and a line of credit, the gap is huge. Here's the honest comparison, with real 2026 rates and a worked example.
The 2026 rates, straight up
- Standard credit card: 19.99% to 22.99% on unpaid balances. That's the going rate in Canada.
- Unsecured line of credit: averaging around 7.94%, and from prime + 1% (about 5.45%) with an excellent file.
- The prime rate at Canada's big banks is 4.45% as of October 2026, with the Bank of Canada's policy rate at 2.25%.
In plain terms: a line of credit costs roughly two to three times less than a card. On a large debt, that changes everything.
The comparison in one table
| Feature | Credit card | Line of credit |
|---|---|---|
| Typical rate (2026) | 19.99% to 22.99% | ~8% on average, from ~5.45% |
| Fixed or variable | Fixed (the rate doesn't move) | Variable (follows prime) |
| Minimum payment | ~3% of balance or $10-$25 | Often interest only |
| Re-borrowing | Easy to reload the card | Easy to re-borrow too |
| Grace period | Yes, if the balance is paid in full | No: interest accrues from day one |
| Rewards | Yes (points, cash back) | No |
| Getting approved | Easy to get a card | Requires a good credit file |
Worked example: $10,000 repaid over 24 months
Take a $10,000 debt, repaid in 24 equal monthly payments.
On a 19.99% card:
- Monthly payment: $508.91
- Total interest: $2,213.82
- Total repaid: $12,213.82
On a 9% line of credit:
- Monthly payment: $456.85
- Total interest: $964.34
- Total repaid: $10,964.34
Savings: $1,249.48 in interest, and $52 less out of pocket every month. That's the equivalent of a free 13th monthly payment. To run the same math with your own rate and balance, our [debt consolidation calculator](/en/debt-consolidation-worth-it) does it in 30 seconds.
The 3 traps of the line of credit (read before signing)
1. The rate is variable. Your line of credit follows prime: if the Bank of Canada raises its rate, your line follows. Simple rule: each extra percentage point costs about $100 a year in interest on a $10,000 balance. Markets watch every Bank of Canada decision closely — check where rates stand before you commit.
2. The temptation to re-borrow. This is trap #1: you move your card balance to the line of credit, the card drops to zero… and six months later, both are maxed again. A line of credit is only a good tool if the card stays in the drawer during repayment.
3. The minimum payment barely repays anything. On many lines of credit, the required minimum covers interest only. Pay just that and your balance won't move for years. Set yourself a fixed monthly payment, like in the example above.
When the card still wins
- If you pay your balance in full every month, the card is unbeatable: $0 in interest + rewards + grace period.
- If your file won't get you a line of credit at a good rate, a low-interest card (some sit around 12.99%, sometimes with 0% temporary balance-transfer offers) can be a stepping stone.
- For small amounts repaid in 2-3 months, the interest difference is tiny: don't overthink it.
The right method: transfer AND freeze
- Transfer the card balance to the line of credit at the best rate you can get.
- Freeze the card: take it out of your wallet (and your online checkouts). Don't close it — an open card at $0 helps your score.
- Set a fixed monthly payment that actually repays principal, not just interest.
- Don't re-borrow on the line of credit until the original balance hits zero.

Secured vs unsecured line of credit: what changes?
There are two main families of lines of credit:
| Type | Typical rate (2026) | Key difference |
|---|---|---|
| Home equity line of credit (secured by your home) | Prime + 0 to 1% (about 4.45% to 5.45%) | Lowest rate, but your home is the collateral |
| Unsecured personal line of credit | ~8% on average, from ~5.45% with an excellent file | No collateral, higher rate |
A home equity line carries the lowest consumer-credit rate on the market. But it turns unsecured debt (your card) into debt secured by your home: if you default for long enough, your property is at stake. Reserve it for solid repayment plans, never for everyday spending.
The 0% balance transfer: a double-edged sword
Some cards offer 0% interest on balance transfers for 6 to 12 months, with transfer fees of 1 to 3%. On $10,000, a 2% fee = $200 for 12 months at 0%: unbeatable on paper.
The trap is twofold: first, any balance left when the promotion ends flips to the regular rate, often around 22.99%. Second, during those 12 months many people ease off — and end up with the original balance plus new debt. If you use this weapon, do the math backwards: $10,000 over 12 months = $834 a month to pay, no exceptions. If that amount doesn't fit your budget, the promotion will trap you.
What about using savings to pay the card?
Worth asking: if your savings earn around 4% and your card charges 19.99%, every dollar you move from savings to the card earns you a guaranteed ~16% spread. Mathematically, killing high-interest debt beats almost any safe investment. The one exception: keep a small emergency cushion first. Emptying your savings completely to pay a card, then facing a surprise car repair with no buffer, just puts you back on the card. Kill the expensive debt — but don't go to zero doing it.
Before moving a balance, check what your card really costs with the [minimum payment calculator](/en/minimum-payment-true-cost) — that's your baseline for judging whether the line of credit is actually cheaper.
The bottom line
For the same debt, a line of credit costs two to three times less than a card: on $10,000 over 24 months, the gap is nearly $1,250. But a line of credit isn't magic: variable rate, temptation to re-borrow, minimums that repay nothing. The tool is only as good as the plan behind it.
Frequently asked questions
Do I need a good credit score to get a line of credit?
Usually, yes: you need a good file and stable income. The rate offered depends on your score: around prime + 1% (≈ 5.45%) for an excellent file, closer to 8% on average. With a weak file, the bank may decline or offer a high rate.
Does a line of credit affect my credit score?
Yes, like any credit product: on-time payments help your score, while late payments and high utilization hurt it. Used well (low balances, on-time payments), a line of credit can even improve your credit mix.
Variable rate: what's the real risk?
Concretely: each extra percentage point costs about $100 a year in interest on a $10,000 balance. Watch Bank of Canada decisions and keep some breathing room in your budget.
Is a low-interest card better than a line of credit?
It depends on the rate you get. A low-interest card around 12.99% (sometimes with 0% temporary balance-transfer offers) can be a good stepping stone if you can't access a line of credit. But an 8-9% line of credit is cheaper in most cases.
I move my balance to my line of credit: then what?
Transfer the balance, put the card aside (without closing it), set a monthly payment that actually repays principal, and don't re-borrow on the line of credit before the original amount hits zero. Without that plan, you risk ending up with both maxed out.
