How do interest and the grace period work?

Credit cards in Canada are revolving credit: you can spend up to your credit limit, and as you pay down your balance you get access to more credit again. If you pay your full balance by the due date each month, you pay no interest on purchases, because federally regulated issuers must give you an interest-free grace period of at least 21 days. If you don't, you pay interest until the balance is paid in full.

That short answer comes from the Financial Consumer Agency of Canada (FCAC), the federal agency that oversees consumer protection at federally regulated financial institutions. Its pages on how credit cards work and on paying off your card explain interest, fees, minimum payments and your rights in plain language.

When is interest charged? The FCAC says you'll pay interest if you don't pay your credit card balance in full by the due date, and you'll keep paying interest until you pay the balance back in full. If you don't pay by the due date, interest is charged from the date you made the purchase.

What is the interest-free grace period? Issuers give a grace period to pay for the previous month's purchases without interest. It begins on the last day of your billing period, which you can find on your statement. Federally regulated financial institutions must provide a minimum 21-day grace period.

Worked example from the FCAC: you buy a smartphone with your card on January 15. On February 1 you receive your January statement, which includes the phone. A 21-day grace period applies to January purchases, so you have until February 21 to pay off the phone and your other purchases without interest.

What rates are typical? Rates vary by institution and type of transaction. The FCAC's example is 19% on regular purchases and 22% on cash advances or cash-like transactions, and it notes that rates on specialized and retail cards may be higher. Your statement and your credit card agreement must clearly show the interest rates you pay.

Can my rate go up? Yes. If you don't make the required minimum payment by the due date, your rate may increase, temporarily or permanently, and you may lose a promotional rate. Federally regulated institutions must notify you before an interest rate increase takes effect.

Which transactions have no grace period? The grace period doesn't apply to cash advances, cash-like transactions and balance transfers. Interest on those starts from the day of the transaction.

What does the minimum payment really cost?

How is the minimum payment set? According to the FCAC, it is either a flat dollar amount, usually $10, plus any interest and fees, or the higher of a dollar amount, typically $10, and a percentage of your outstanding balance, typically 3%. Your credit agreement says which method your issuer uses. Since August 1, 2025, the minimum payment for Quebec residents is 5%.

Why does paying only the minimum hurt? It takes longer to pay off your balance and you pay more interest. The FCAC's worked example: on a $2,000 balance at 18%, paying $60 a month takes 3 years and 11 months and costs $793 in interest, for $2,793 in total. Paying $160 a month (the minimum plus $100) clears it in 1 year and 2 months with $231 of interest, for $2,231 in total.

Will my statement show this? If your issuer is federally regulated, your statements must include the time needed to pay off the balance by making only the minimum payment.

How are my payments applied? Different rates may apply to different parts of your balance. Typically, the minimum payment goes to the portion with the lowest rate. Anything above the minimum goes either to the portion with the highest rate or proportionally to the whole balance. Federally regulated issuers can decide how they apply your minimum payment, so check your agreement.

What if a due date falls on a weekend? Issuers process payments on business days. If a payment is due on a weekend or holiday, paying the next business day counts as on time. Processing time depends on how you pay, so find out how long each method takes.

What happens if I miss a payment? The FCAC lists the risks: a higher interest rate, damage to your credit score, losing a promotional rate, and your institution cancelling your card.

What is a payment holiday? Some issuers let you skip a payment, but you'll still pay interest. Federally regulated issuers must tell you clearly, with the offer, whether interest applies.

Cash advances, balance transfers and other fees

Is a cash advance expensive? It can be very expensive. There is no grace period: you pay interest from the date of the advance until it is repaid in full, usually at a higher rate than purchases. You may also pay a fee each time, set as a fixed amount, a percentage, or both. The FCAC suggests considering a cheaper option such as a personal loan or line of credit first; compare those with our

What counts as cash-like? Institutions often treat wire transfers, money orders, travellers' cheques and gaming transactions such as bets, casino chips and lottery tickets like cash advances, with interest from day one and possibly a fee.

What about credit card cheques? Convenience or promotional cheques are charged interest from the date you use them, usually at a higher rate than purchases. If you don't want them, the FCAC suggests cutting them up and asking your issuer to stop sending them.

How do balance transfers work? You move a balance from an old card to a new one, generally at a lower rate. There is usually a fee, often a percentage: a 3% fee on a $1,000 transfer is $30. You still pay interest on the transferred amount, and promotions usually last only a set period.

Can a merchant charge me extra for paying by card? Merchants may add a surcharge, except in Quebec, of up to 2.4%. They must tell you before processing the payment and disclose it at the point of sale, at the store entrance and on every receipt.

Other fees to look for: over-the-limit fees, reprinting fees for old statements, dishonoured payment fees when a payment bounces for non-sufficient funds, and inactive account fees. Some institutions may close a card that has been inactive for a year.

Credit limits, foreign purchases and your rights

Can my issuer raise my limit without asking? No. Your issuer must get your express consent, in writing or verbally, before increasing your credit limit, and must confirm the change in writing no later than your next statement.

When can't they charge an over-limit fee? Federally regulated institutions can't charge it in certain cases, such as when a merchant's temporary hold pushes you over. The FCAC's example: you have $90 of credit left, a gas station places a $100 hold, and you fill up for $20. No over-limit fee can be charged.

What does spending abroad cost? Your institution applies an exchange rate plus a foreign currency conversion charge. The FCAC's example: a €1,000 purchase at an exchange rate of 1.45 is $1,450; a 2.5% conversion charge adds $36.25, for a total of $1,486.25. Cash advances abroad typically carry higher fees, and refunds on foreign purchases may differ from the original amount because exchange rates change daily.

What should my statement show? The FCAC says it includes the period covered, opening and closing balances, the interest rates applied and total interest charged, your credit limit and available credit, the minimum payment and due date, and each transaction.

Where do I complain? Federally regulated financial institutions must have a process to resolve disputes with consumers. Start with your issuer's complaint process.
