The CIBC Costco Mastercard is a cash back credit card issued by the Canadian Imperial Bank of Commerce (CIBC) for eligible Costco members in Canada. The card has no annual credit-card fee and offers different cash back rates depending on where and how cardholders spend. Key categories include Costco gas, restaurants, other eligible gas stations, electric vehicle charging, Costco.ca purchases, and general purchases.
The most important detail for Costco shoppers is that the highest advertised cash back rate does not apply to every purchase made at Costco. According to CIBC’s published card information, eligible purchases at Costco gas in Canada and qualifying restaurants can earn 3% cash back. Eligible gas purchases outside Costco, qualifying EV charging, and eligible Costco.ca purchases can earn 2%, subject to applicable annual spending thresholds. Other qualifying purchases generally earn 1%.
The card also functions as a Costco membership card and operates on the Mastercard network, allowing cardholders to use it beyond Costco wherever Mastercard is accepted, subject to merchant acceptance.
Because credit-card rates, fees, insurance coverage, promotions, and reward terms can change, consumers should confirm the current terms with CIBC and Costco Canada before applying or making a financial decision.
Review the CIBC Costco Mastercard at a Glance
The CIBC Costco Mastercard combines a Costco membership credential, a Mastercard credit account, and a cash back rewards program. Costco membership is required to apply, while CIBC is responsible for issuing and administering the credit card.
The card has no annual credit-card fee, but Costco membership itself is not free. Those are separate products and separate costs. Holding a Costco membership makes a consumer eligible to apply for the card, but approval remains subject to CIBC’s credit requirements.
Here is a simplified overview of key features:
| Feature | CIBC Costco Mastercard details |
|---|---|
| Card issuer | CIBC |
| Payment network | Mastercard |
| Costco membership required | Yes |
| Annual credit-card fee | $0 |
| Costco gas in Canada | Up to 3% cash back |
| Eligible restaurants | 3% cash back |
| Other eligible gas | 2% cash back within applicable threshold |
| Eligible EV charging | 2% cash back within applicable threshold |
| Eligible Costco.ca purchases | 2% within applicable threshold |
| Other qualifying purchases | 1% |
| Regular Costco warehouse merchandise | Generally 1% |
| Foreign currency conversion fee | 2.5% under current disclosure |
| Purchase protection | Included, subject to policy terms |
| Extended warranty | Included, subject to policy terms |
| Mobile device insurance | Included, subject to policy terms |
CIBC’s current published terms should always take priority over summaries because merchant classifications, exclusions, annual limits, insurance provisions, and other conditions can affect the actual benefit received.
Check the CIBC Costco Mastercard Eligibility Requirements
Applicants need a valid Costco membership to apply for the CIBC Costco Mastercard. CIBC identifies the product as a Costco-member credit card and also requires authorized users added to the account to hold the necessary Costco membership.
Costco membership does not guarantee credit approval. CIBC is the lender and evaluates applications according to its credit criteria, identity-verification requirements, and other applicable conditions. An applicant should therefore distinguish between being eligible to submit an application and being approved for credit.
This separation also determines who handles different account issues. Costco manages the underlying membership relationship, while CIBC manages the credit-card account. Billing questions, card transactions, credit limits, interest, statements, and most credit-card servicing matters are generally handled through CIBC.
Applicants should review the eligibility conditions displayed during the current CIBC application process rather than relying on an older review. Credit requirements and promotional offers can change over time.
Compare the CIBC Costco Mastercard Cash Back Rates
The CIBC Costco Mastercard uses category-based cash back rates. It does not provide the same percentage on every purchase.
Eligible Costco gas purchases in Canada can earn 3%, and qualifying restaurant purchases can also earn 3%. Other eligible gas and qualifying EV charging transactions can earn 2%, subject to the applicable annual category limit. Eligible Costco.ca transactions can earn 2% within their own annual spending threshold.
Other qualifying purchases generally earn 1%.
| Spending category | Cash back rate | Key consideration |
|---|---|---|
| Eligible Costco gas in Canada | 3% | Subject to applicable gas-category terms |
| Eligible restaurants | 3% | Merchant classification matters |
| Other eligible gas stations | 2% | Enhanced rate subject to annual threshold |
| Eligible EV charging | 2% | Enhanced rate subject to annual threshold |
| Eligible Costco.ca purchases | 2% | Enhanced rate subject to annual threshold |
| Regular Costco warehouse merchandise | Generally 1% | Falls under standard qualifying spending |
| Other qualifying purchases | 1% | Standard cash back rate |
CIBC’s benefits documentation states that enhanced gas and EV charging rates are subject to the first $5,000 in applicable net annual card purchases in that category. Costco.ca’s enhanced rate applies to the first $8,000 in applicable net annual card purchases in its category. Spending above an applicable threshold generally returns to the standard 1% rate under the card terms.
The exact reward can also depend on how the payment network classifies a merchant. A purchase does not necessarily qualify for an enhanced rate merely because the consumer considers the merchant a restaurant, gas station, or similar business.
Calculate Cash Back on Costco Warehouse Purchases

Regular Costco warehouse merchandise purchases generally earn 1% cash back through the CIBC Costco Mastercard.
This is one of the most important details to understand before applying. The Costco name on the card does not mean every Costco purchase earns 2% or 3%. Higher rates are attached to specified categories, including eligible Costco gas and Costco.ca transactions.
For example, assume a cardholder spends $6,000 on qualifying Costco warehouse merchandise during the year and all of those transactions receive the standard 1% rate.
$6,000 × 1% = $60 cash back
By comparison, $6,000 of qualifying purchases earning 3% would theoretically produce $180, assuming no category threshold or other restriction affected those transactions.
Consumers should also distinguish CIBC credit-card cash back from Costco Executive Membership rewards. They are separate programs governed by separate terms. Receiving a reward through one program does not automatically determine what is earned through the other.
Maximize the 3% Restaurant Cash Back Category
Eligible restaurant purchases earn 3% cash back, making restaurants one of the card’s strongest everyday spending categories.
Suppose a cardholder spends $250 per month at qualifying restaurants. Annual spending would equal $3,000:
$250 × 12 = $3,000
At a 3% cash back rate:
$3,000 × 3% = $90
The calculation is straightforward, but eligibility can depend on the merchant category assigned to the transaction. Payment networks use merchant classification codes to identify the type of business processing a purchase.
As a result, buying prepared food does not necessarily guarantee that the transaction will receive the restaurant rate. A food purchase made through a merchant categorized differently could earn another applicable rate.
Cardholders should therefore evaluate rewards using eligible transactions rather than assuming that every food-related purchase automatically qualifies for 3%.
Earn 3% Cash Back at Eligible Costco Gas Stations
The CIBC Costco Mastercard offers 3% cash back on eligible Costco gas purchases in Canada, subject to the card’s terms and applicable annual spending threshold.
This category can be particularly relevant for Costco members who regularly refuel at Costco.
For example, $2,500 of eligible Costco gas purchases earning 3% would generate:
$2,500 × 3% = $75
The card provides a different rate at other qualifying gas stations. Eligible non-Costco gas transactions generally receive 2% within the applicable enhanced-rate threshold.
CIBC groups enhanced gas and EV charging rewards under an annual spending limit. Its published benefits information identifies the first $5,000 of applicable net annual card purchases as the relevant threshold for enhanced rates in this category. Purchases beyond the threshold generally earn 1% under the program terms.
Returns and credits can also affect net annual purchases, so gross spending alone does not necessarily determine the final reward.
Earn 2% at Other Eligible Gas and EV Charging Merchants
Eligible gas purchases made away from Costco and qualifying electric vehicle charging transactions can earn 2% cash back within the applicable annual threshold.
For example, $2,000 in eligible non-Costco gas purchases at 2% would produce:
$2,000 × 2% = $40
Likewise, $1,000 of qualifying EV charging purchases at 2% would produce $20, assuming those transactions meet CIBC’s requirements and remain within the relevant spending threshold.
The inclusion of EV charging makes the category useful beyond traditional gasoline purchases. However, merchant classification remains important. A transaction must qualify according to the payment network and CIBC program rules to receive the enhanced rate.
Cardholders should consult CIBC’s current benefits guide when determining whether a particular transaction qualifies.
Earn 2% Cash Back on Eligible Costco.ca Purchases

Eligible purchases through Costco.ca can earn 2% cash back on the first $8,000 of applicable net annual card purchases in the category under CIBC’s published benefits terms.
If a cardholder makes $5,000 in eligible Costco.ca purchases during the applicable period:
$5,000 × 2% = $100
If the cardholder reaches the $8,000 threshold entirely through eligible purchases receiving 2%, the enhanced portion would produce:
$8,000 × 2% = $160
Additional qualifying Costco.ca spending above the applicable threshold generally earns 1%.
This creates an important distinction between online and warehouse spending. Regular qualifying merchandise bought inside a Costco warehouse generally receives 1% through the credit card, while eligible Costco.ca purchases receive the enhanced 2% rate within the stated threshold.
Consumers who make substantial Costco purchases should consider this difference when estimating potential annual cash back.
Estimate Annual CIBC Costco Mastercard Cash Back
The most useful way to estimate the card’s value is to calculate rewards from actual household spending rather than focusing exclusively on the advertised “up to 3%” rate.
Consider a hypothetical cardholder with the following annual qualifying spending:
| Spending | Amount | Assumed rate | Estimated cash back |
|---|---|---|---|
| Costco gas | $2,000 | 3% | $60 |
| Restaurants | $3,000 | 3% | $90 |
| Costco.ca | $2,500 | 2% | $50 |
| Other eligible gas/EV charging | $1,500 | 2% | $30 |
| Costco warehouse merchandise | $5,000 | 1% | $50 |
| Other qualifying purchases | $6,000 | 1% | $60 |
| Estimated total | $20,000 | $340 |
This example produces approximately $340 in annual cash back. It is an illustration, not a guarantee.
Actual rewards can differ because of merchant classifications, returns, refunds, annual category thresholds, excluded transactions, and changes to CIBC’s reward terms.
A personalized estimate should therefore use the cardholder’s real spending and current CIBC program rules.
Review the CIBC Costco Mastercard Annual Fee
The CIBC Costco Mastercard currently has a $0 annual credit-card fee.
CIBC’s published rates-and-fees documentation also lists no annual fee for authorized users under the applicable terms. This can reduce the fixed cost of maintaining the account compared with rewards cards that charge an annual fee.
However, the $0 card fee should not be confused with a free Costco membership. A valid Costco membership is required to obtain the card, and Costco membership has its own cost.
Other card charges can also apply. Depending on account activity, these can include purchase interest, cash-advance interest, foreign currency conversion charges, and transaction-related fees.
“No annual fee” therefore describes one specific account charge. It does not mean using credit through the account can never create costs.
Check the CIBC Costco Mastercard Purchase Interest Rate
CIBC’s current published rates-and-fees summary lists a 21.75% annual interest rate on purchases when the CIBC Costco Mastercard account is opened.
The issuer also publishes separate rates for cash advances, balance transfers, and convenience cheques. CIBC currently lists a 22.49% rate for those transactions, with 21.99% for Quebec residents, subject to the applicable disclosure and account terms.
Interest rates can increase under conditions specified by CIBC, including certain missed-payment situations.
These borrowing costs are significant when compared with the card’s reward percentages.
For example, earning 3% on a purchase does not make carrying an interest-bearing balance financially equivalent to receiving a 3% discount. Cash back and interest are separate calculations, and interest charges can outweigh rewards when balances remain unpaid.
Consumers who plan to carry balances should examine borrowing costs carefully rather than choosing a card primarily for cash back.
Use the Interest-Free Grace Period Correctly
CIBC states that the payment due date is at least 21 days after the statement date under its current disclosure. Eligible purchases can benefit from an interest-free grace period when payment requirements are met.
The grace period does not apply in the same manner to every type of credit-card transaction. In particular, cash advances and similar transactions can begin accruing interest without the purchase grace period.
This distinction matters because consumers sometimes treat cash withdrawals from a credit card like ordinary purchases. They are not financially equivalent.
Anyone using the card should review the statement balance, minimum payment, payment due date, and transaction type. Paying only the minimum required amount can keep an account current under applicable terms but may still result in substantial interest on the remaining balance.
The current CIBC cardholder agreement and rates-and-fees disclosure provide the controlling details.
Account for the Foreign Currency Conversion Fee
The CIBC Costco Mastercard is not marketed as a no-foreign-transaction-fee card. CIBC’s current disclosure applies a 2.5% foreign currency conversion fee to applicable converted foreign-currency transactions.
Suppose an international purchase converts to C$1,000 before the conversion fee.
A 2.5% fee would equal:
$1,000 × 2.5% = $25
That cost should be considered alongside any cash back earned on the transaction.
This is particularly relevant for frequent travellers and consumers who regularly purchase from foreign merchants. A reward rate should not be considered independently from transaction costs.
Exchange-rate calculations and the timing of currency conversion can also affect the final Canadian-dollar amount charged. Cardholders should consult CIBC’s current disclosure for the exact conversion methodology.
Review the Purchase Security Coverage
The CIBC Costco Mastercard includes Purchase Security insurance, subject to the applicable Certificate of Insurance.
CIBC’s insurance summary states that most eligible new personal property can receive coverage against qualifying loss, theft, or damage for 90 days from the purchase date, subject to exclusions, conditions, and coverage limits.
This protection can add value when purchasing items such as eligible electronics, household goods, or other personal property with the card.
However, insurance should not be described as covering every purchase. Certain property, events, circumstances, or transaction methods may be excluded. Claims also require supporting documentation and compliance with policy conditions.
Anyone relying on the insurance for an expensive purchase should review the current Certificate of Insurance before completing the transaction rather than relying solely on a short marketing summary.
Use the Extended Warranty Benefit
The card also includes Extended Warranty insurance for qualifying purchases.
According to CIBC’s insurance information, the benefit can double the original manufacturer’s warranty period for eligible items for up to one additional year, subject to the insurance contract.
For example, an eligible product with a one-year manufacturer’s warranty could potentially receive an additional year of coverage through the card’s insurance benefit if all policy requirements are satisfied.
The benefit does not automatically extend every warranty. Product eligibility, original warranty terms, purchase method, exclusions, documentation, and other requirements can affect coverage.
Cardholders should keep purchase receipts and warranty documentation for eligible products. These records may be required when making a claim.
Review the Mobile Device Insurance Benefit
The CIBC Costco Mastercard also includes Mobile Device Insurance for eligible devices.
CIBC’s published insurance summary lists coverage of up to $1,000 per occurrence, per insured person for qualifying loss, theft, or accidental damage involving an eligible mobile device.
Eligible devices can include smartphones, cell phones, and tablets when the purchase or financing arrangement meets the policy requirements.
The $1,000 amount is a maximum coverage figure, not a guaranteed reimbursement. Deductibles, depreciation, exclusions, claim documentation, and other policy conditions can reduce the amount payable.
Consumers purchasing an expensive smartphone specifically because of this benefit should read the full insurance certificate first. How the device is purchased or financed with the card can affect eligibility.
Use the CIBC Costco Mastercard Outside Costco
The CIBC Costco Mastercard can be used beyond Costco because it operates on the Mastercard network.
That means the card can generally be used at merchants accepting Mastercard, subject to merchant, account, and network restrictions. Cardholders can use it for restaurants, fuel, retail purchases, online shopping, subscriptions, and many other types of spending.
Cash back continues to depend on the transaction category. A qualifying restaurant can receive 3%, an eligible non-Costco gas transaction can receive 2% within the applicable threshold, and ordinary qualifying purchases generally receive 1%.
This makes the card a general-purpose credit card rather than a payment product that works only at Costco.
Consumers should still compare its category rates with their actual spending. A card can be useful for one category without necessarily providing the strongest reward rate for every transaction.
Use the Card at Costco Canada Warehouses

The CIBC Costco Mastercard can be used for purchases at Costco Canada warehouses.
Costco Canada’s payment policies identify Mastercard as an accepted credit-card network at Canadian warehouses. This is an important geographic distinction because Costco payment methods are not identical in every country.
Canadian shoppers should therefore rely on Costco Canada’s official payment information rather than applying U.S. Costco payment rules to Canadian warehouses.
Payment options can also vary among Costco warehouses, Costco gas stations, and Costco.ca. A payment method accepted online may not necessarily be accepted in exactly the same way at every other Costco sales channel.
The CIBC Costco Mastercard is specifically designed around Costco’s Canadian membership ecosystem and should be evaluated according to Canadian terms.
Redeem CIBC Costco Mastercard Cash Back
Cash back earned through the CIBC Costco Mastercard is accumulated according to CIBC’s rewards terms rather than deducted instantly from each purchase.
For example, a $100 eligible restaurant transaction that earns 3% still appears as a $100 purchase. The $3 reward is calculated separately through the cash back program.
This distinction is important because cash back is not the same as an immediate point-of-sale discount.
Cardholders should also distinguish CIBC cash back from any reward associated with an eligible Costco Executive Membership. The credit-card reward belongs to the CIBC program, while Costco membership rewards operate according to Costco’s separate conditions.
The current CIBC benefit guide and account information should be used to confirm certificate issuance, redemption procedures, timing, and other cash back rules because these details can change.
Compare the CIBC Costco Mastercard With the Costco World Mastercard
Consumers may encounter both the CIBC Costco Mastercard and CIBC Costco World Mastercard while researching the card.
The two products are related, and CIBC’s published documentation covers several common features. However, consumers should check which version they qualify for and which card is actually being offered during the application process.
CIBC currently lists no annual card fee for the Costco Mastercard and Costco World Mastercard. Its published rates-and-fees document also provides applicable interest-rate information for both products.
Insurance documentation can likewise cover both versions.
The safest approach is to read the documentation attached to the specific account rather than assuming that every benefit mentioned for one Costco-branded CIBC product automatically applies identically to another.
Separate the Personal Card From the CIBC Costco Business Mastercard
The CIBC Costco Business Mastercard is different from the personal CIBC Costco Mastercard.
The business product is intended for eligible Costco members seeking a card for business-related spending. CIBC publishes a separate reward structure and benefits for that product.
Depending on current terms, business-card categories can include Costco gas, restaurants, Costco.ca, Costcobusinesscentre.ca, shipping, insurance services, other eligible gas, and EV charging.
This distinction is important when reading online comparisons. A benefit advertised for the business card should not automatically be attributed to the personal card.
Consumers should confirm the full product name whenever comparing rewards, welcome offers, insurance, interest rates, and eligibility conditions.
Evaluate Whether the CIBC Costco Mastercard Fits Your Spending
The usefulness of the CIBC Costco Mastercard depends heavily on where a household spends money.
A member who regularly buys Costco gas and frequently eats at qualifying restaurants may benefit substantially from the 3% categories. Someone who makes significant eligible purchases through Costco.ca can benefit from its 2% rate within the annual threshold.
A consumer who primarily shops for merchandise inside Costco warehouses should recognize that those regular purchases generally earn 1% through the credit card.
Consider two hypothetical Costco members.
Member A spends heavily at restaurants, Costco gas, and Costco.ca. A larger percentage of Member A’s spending falls into 2% and 3% categories.
Member B spends almost exclusively on merchandise inside Costco warehouses. Most of Member B’s spending earns the standard 1% rate.
Even if both spend the same amount annually, their cash back totals can be different.
This is why evaluating personal spending patterns provides more useful information than looking only at the maximum advertised reward rate.
Apply for the CIBC Costco Mastercard Safely
Eligible Costco members can apply for the CIBC Costco Mastercard through CIBC, subject to approval.
Before submitting an application, verify the current annual fee, interest rates, reward rates, category thresholds, insurance benefits, eligibility criteria, and promotional offers directly with CIBC.
Applicants should also understand that credit-card applications can involve a credit assessment. Costco membership alone does not guarantee approval.
Use CIBC’s official website or an authorized CIBC application channel rather than entering financial information into an unfamiliar third-party website.
Never provide online banking passwords, one-time security codes, or other sensitive authentication information to someone claiming they can guarantee approval.
CIBC’s official Costco credit-card page contains the current product information and application process.
Manage the CIBC Costco Mastercard Account
CIBC manages the credit portion of the CIBC Costco Mastercard. Cardholders can use CIBC’s supported banking channels to handle account functions such as reviewing transactions, checking statements, making payments, and accessing other available card services.
The card must be activated after it is received before normal use. Cardholders should follow the activation instructions supplied with the card or use an official CIBC activation channel.
Costco and CIBC have different responsibilities. CIBC generally handles the credit-card account, while Costco handles membership-related matters.
Recognizing this distinction can save time when seeking assistance. A billing dispute or credit-card payment question belongs with the issuer, whereas a Costco membership-status issue belongs with Costco.
Cardholders should use the current contact information printed on their card, statement, or official CIBC website when account-specific assistance is required.
Protect the Value of Your Cash Back Rewards
Cash back is most valuable when reward earnings are not overwhelmed by avoidable borrowing costs.
Consider a cardholder who earns $300 in cash back over a year. If that person simultaneously pays hundreds of dollars in purchase interest, the rewards alone do not show the complete financial result of using the card.
The same principle applies to foreign currency fees and cash advances.
The card’s highest standard advertised cash back rate is 3%, while CIBC’s published purchase interest rate is considerably higher on an annual basis. These percentages measure different things and should not be directly treated as equivalents, but the comparison illustrates why borrowing costs deserve attention.
Consumers should therefore evaluate a rewards card using four factors together: cash back earned, annual card costs, transaction fees, and interest paid.
This provides a more accurate measure of actual card value than reward percentages alone.
Verify Current CIBC Costco Mastercard Terms Before Applying
Credit-card terms can change. A review written today can become outdated if CIBC modifies an interest rate, reward category, insurance benefit, spending threshold, promotional offer, or eligibility requirement.
For that reason, consumers should use independent articles for explanation and use CIBC’s official disclosure documents for the final financial decision.
Key documents to verify include the current rates-and-fees summary, CIBC Costco Mastercard benefits guide, cardholder agreement, and applicable Certificate of Insurance.
Costco Canada’s official customer-service resources should be used for questions about Costco membership and accepted payment methods.
This approach provides stronger protection against outdated information than relying on copied credit-card summaries or social-media posts.
Review the CIBC Costco Mastercard Before Making a Decision
The CIBC Costco Mastercard offers a straightforward combination of Costco membership integration, Mastercard acceptance, and category-based cash back without an annual credit-card fee.
Its strongest advertised categories include 3% cash back at eligible restaurants and Costco gas in Canada, followed by 2% at other eligible gas stations, qualifying EV charging merchants, and Costco.ca, subject to applicable spending thresholds. Other qualifying purchases generally earn 1%.
For Costco shoppers, the most important point is that regular Costco warehouse merchandise purchases generally earn 1% through the credit card. The Costco branding does not create a universal 3% reward on Costco spending.
The card also provides insurance benefits that can include Purchase Security, Extended Warranty, and Mobile Device Insurance, subject to the full policy conditions. At the same time, consumers should account for purchase interest, foreign currency conversion fees, and other possible account charges.
Ultimately, the card’s practical value depends on the cardholder’s spending pattern and account management. Before applying, verify all current rates, rewards, insurance coverage, fees, and eligibility requirements through CIBC’s official documentation.
