Everything Canadians need to know about credit card interest rates — average rates, how interest is calculated, strategies to avoid it, and best low-interest options. Updated March 2025.
| Rate Type | Typical Rate | Low-Interest Option |
|---|---|---|
| Standard Purchase Rate | 19.99% – 22.99% | 12.99% (MBNA True Line) |
| Cash Advance Rate | 22.99% – 24.99% | 12.99% (True Line) |
| Balance Transfer Promotional | 0% – 2.99% (intro) | 0% for 6–12 months |
| Retail/Store Cards | 24.99% – 29.99% | N/A |
If you carry a $3,000 balance on a 19.99% card and make only minimum payments (~2.5% of balance, or $40/month minimum), it will take over 15 years to pay off and cost more than $3,600 in interest — more than the original balance. Always pay in full when possible.
Canadian credit card interest is calculated using the Average Daily Balance method:
Example: $1,000 average daily balance × (19.99% ÷ 365) × 30 days = approximately $16.43 in interest per month, or ~$197/year on a $1,000 balance.
Canadian credit cards are required to offer a minimum 21-day grace period from the statement closing date to the payment due date. During this grace period, if you pay your entire statement balance by the due date, you pay zero interest — even on purchases made 50+ days ago.
The grace period only applies if you carry no balance forward from the previous month. Once you carry any balance, interest begins accruing immediately on new purchases with no grace period.
| Card | Purchase Rate | Annual Fee |
|---|---|---|
| MBNA True Line Mastercard | 12.99% | $0 |
| MBNA True Line Gold Mastercard | 8.99% | $39 |
| TD Emerald Flex Rate Visa | Prime + 4.5% (variable) | $25 |
| RBC Visa Classic Low Rate | 12.99% | $20 |
| BMO Preferred Rate Mastercard | 12.99% | $20 |
Low-interest cards typically don't offer rewards or cash back — the tradeoff is a lower rate if you occasionally carry a balance. If you always pay in full, a rewards card is always the better choice regardless of interest rate. See our balance transfer cards guide for 0% promotional offers.

Try KOHO — Code 45ET55JSYACanadian credit card interest rates have been remarkably stable at 19.99% for purchase rates despite significant changes in the Bank of Canada's policy rate. During the 2020–2024 rate cycle, the overnight rate moved from 0.25% to 5%, but credit card purchase rates barely moved. This is because credit card rates reflect default risk and operating costs more than bank funding costs. The prime-rate-linked low-interest cards like TD Emerald Flex (Prime + 4.5%) did fluctuate with Bank of Canada rate changes, making them more expensive during the high-rate period — an important consideration for variable-rate credit cards.
Credit card minimum payments are typically 2–3% of the outstanding balance or $10, whichever is higher. This minimum payment schedule is designed to maximize interest income for the card issuer over the longest possible repayment period. On a $5,000 balance at 19.99%, making only minimum payments stretches repayment to approximately 22 years and results in $7,700 in total interest paid — 2.5x the original balance. If you can pay $300/month instead, the debt is eliminated in 20 months with only $995 in interest. The difference between minimum and aggressive payment is $6,700 saved — more than many Canadians earn in a month after tax.
According to the Financial Consumer Agency of Canada, approximately 29% of Canadian credit cardholders carry a balance from month to month. The average balance carried by revolving cardholders is approximately $3,800. With the average purchase rate at 19.99%, the average indebted cardholder pays approximately $760/year in interest — enough to fund a weekend trip or eliminate a monthly bill. Understanding and avoiding this trap is the single most valuable financial action available to the nearly one-third of Canadians who currently carry balances.
One of the most underused tools available to Canadian credit cardholders: calling your credit card issuer to negotiate a lower interest rate. This works most effectively for longtime customers with strong payment histories who are facing temporary financial hardship. Banks prefer to temporarily reduce rates rather than lose a customer to a competitor or face a default. Call the number on the back of your card, ask for the "customer loyalty" or "retention" team, explain your situation clearly, and ask for a rate reduction or hardship program.
Success rates vary by issuer and individual circumstances, but many Canadians have successfully had rates reduced from 19.99% to 10–14% for 6–12 months during difficult periods. Even a temporary reduction on a $5,000 balance saves $50–$100/month in interest — a meaningful amount during financial recovery. This is a completely legitimate request that costs nothing to make and has a reasonable probability of success for customers in good standing.
For persistent high-balance situations where negotiation hasn't worked, consider a formal credit counseling referral. Non-profit credit counseling agencies across Canada (NFCC members) offer free or low-cost debt management programs that can consolidate multiple credit card balances into a single reduced-rate payment plan that major issuers participate in. These programs affect your credit score but may be the most practical path for balances that have grown beyond what balance transfers or personal discipline can resolve.
