The CIBC Costco Mastercard is a no-fee credit card built around one specific place: Costco. It doubles as your Costco membership card and pays cash back on nearly everything you buy, with higher rates on restaurants, gas, and Costco.ca.
The catch is right in the name — you need an active Costco membership to hold this card. If you already shop there regularly, that’s not a hurdle. If you don’t, it’s worth weighing the membership cost against the cash back you’d actually earn.
There’s no annual fee on the card itself, and up to three additional cardholders can be added at no extra cost. Beyond cash back, it also comes with a few lifestyle perks: a free Skip+ membership when linked to a Skip account, discounted Disney+ for six months, and low-fee international money transfers.
Who This Card Makes Sense For
This card is a good fit if you:
- Already have, or plan to keep, a Costco membership
- Fill up at Costco gas stations or eat out often
- Want a single card that covers groceries, gas, and everyday spending
- Don’t want to pay an annual fee for cash back
It’s a weaker fit if you:
- Don’t shop at Costco and have no plans to join
- Spend often outside Canada, since foreign purchases carry a conversion fee
- Want travel perks or a rewards program beyond straight cash back
Worth noting: the card’s insurance coverage extends past just purchases. It includes mobile device insurance up to $1,000 for repair or replacement, plus purchase security and extended warranty that adds a year to most manufacturer warranties.
Eligibility and Documents Needed
CIBC lists a minimum annual income of $15,000 for this card, plus a valid Costco membership. Beyond that, general CIBC credit card rules apply: you need to be the age of majority in your province (18 or 19), a Canadian citizen or resident, and you can’t have filed for bankruptcy in the past 7 years.
When you apply, be ready to provide:
- Full legal name and date of birth
- Home address, phone number, and email
- Current and previous employer details
- Gross annual income and details of other credit cards you hold
Your Social Insurance Number is optional on the application, not required. CIBC also asks about any other credit cards you currently hold, since that factors into the overall credit assessment alongside your income and history.
How to Apply
You can apply online, by phone, or in person at a CIBC branch. CIBC says the online application takes about 5 minutes, with a response in as little as 60 seconds.
Not every application clears instantly, though. If yours needs a manual review, CIBC says it can take roughly 2 to 3 weeks to hear back with a final decision. Missing details on the application, like employment history or income, is the most common reason for that delay.
Fees and Conditions
The numbers that matter most:
- Annual fee: $0 (including up to 3 additional cards)
- Purchase interest rate: 21.75%
- Cash advance rate: 25.99%
- Foreign currency conversion fee: 2.5% of the converted amount
With no annual fee, the math is simple: cash back you earn isn’t offset by a yearly charge. The trade-off is the interest rate, which is high enough that carrying a balance quickly erases any rewards you’ve earned.
Cash back is tiered by category, with no annual cap on how much you can earn:
- 3% at restaurants and Costco gas stations
- 2% at other gas stations, EV charging stations, and Costco.ca
- 1% on everything else, including in-warehouse Costco purchases
In practice, this card rewards people who genuinely use Costco as their main grocery and gas stop, rather than someone who visits occasionally for a bulk-buy run. The membership fee is the real cost to weigh here — the cash back needs to outpace it for the card to pay for itself.
Frequently Asked Questions
Do I need a Costco membership to get this card?
Yes. The CIBC Costco Mastercard doubles as your Costco membership card, so an active membership is required to hold it.
Is there a cap on how much cash back I can earn?
No. CIBC doesn’t set an annual limit on cash back earned across any of the card’s spending categories.
What’s the current welcome offer?
New cardholders can earn a $30 statement credit after approval, a first purchase, and enrolling in eStatements within 90 days. This offer is set to end September 20, 2026, so confirm the current terms before applying.
Does this card charge extra for purchases outside Canada?
Yes. Foreign currency purchases carry a 2.5% conversion fee, which is standard for most Canadian credit cards without travel-focused perks.
Can I add authorized users to this card?
Yes, up to three additional cardholders, and there’s no extra fee for adding them. Each still needs to be on the same Costco membership to use the card at Costco.
