3 Capital One Costco Mastercard pros

There are 3 things we like about the Capital One Mastercard.

1. High earn rates on restaurants and gas

For a credit card with no annual fee, this card has high earn rates for both restaurants and gas.

On these purchases, you’ll earn:

  • 3% on restaurants, and
  • 2% on gas.

Your rewards will add up quickly if you spend quite a bit eating out or getting gas.

2. Complimentary insurance coverage

The insurance coverage is also comprehensive when compared to other no annual fee cards.

You’ll get 6 types of insurance coverage included:

  • Extended warranty (up to 2 years instead of the usual 1)
  • Purchase protection (120 days instead of the usual 90)
  • Price protection
  • Travel accident (up to $250,000)
  • Baggage delay (up to $300)
  • Rental car theft & damage

The price protection is quite notable, and not many credit cards in Canada include it. In fact, only 6% of credit cards we track include it.

3. Doubles as your Costco membership card

You’ll be able to leave your Costco membership card at home if you have this credit card. That’s because it doubles as your membership card, picture and all, saving some room in your wallet.

4 Capital One Costco Mastercard cons

There are also some things we don’t like about the Capital One Costco Mastercard.

1. Base earn rate not as good as advertised

The base earn rate is less than what you can find on other no fee cards, and the marketing language makes it seem better than it is. It says you earn up to 1% back on all other purchases.

That “up to” part? The Capital One Costco Mastercard only earns 0.5% cash back on the first $3,000 in annual non-category spend, before jumping up to 1%. That means you’ll get $15 less than what you would be earning if the rate was just a flat 1%.

2. No special earn rates for shopping at Costco

Despite the fact it’s a Costco branded credit card, there’s no special earn rate when shopping at Costco.

Meaning, you’ll be earning between 0.5% to 1% on your Costco purchases with this card. That’s not that great considering top flat rate cash back credit cards will get you 2% back on all your Costco purchases.

3. Rewards paid out once per year as a Costco rebate coupon

Your rewards are only paid out once per year, and can only be used at a Costco warehouse in the form of a rebate coupon at the cash register.

There is the option to go to Costco and exchange it for cash if you like.

4. Not a real cash back credit card

Since your rewards are paid out as a Costco rebate coupon, the Capital One Costco Mastercard isn’t a real cash back credit card. That means you’re losing out on a major perk of cash back cards – the convenience of using your rewards on anything you buy. With this card, you’re limited to Costco purchases unless you go through the hassle of getting your coupon converted to cash at the store.

If you tend to carry a balance, this credit card will save you on interest, for a low annual fee of $25.

Packaged in there is one of the top travel insurance packages of any travel credit card in Canada, giving you 14 out of possible types of credit card insurance.

Finally, you get a complimentary membership for Mastercard Airport Experiences provided by LoungeKey and 2 free lounge passes that gives you access to some of the best airport lounges worldwide.

To get maximum value for your AIR MILES, you’ll need to redeem them for flights which do have highly variable value. If you choose AIR MILES Cash as your reward choice, you’ll get a value of 10.5 cents for each mile. But, if you look for reasonably high value flights, you should be able to score a higher value in the range of 17.2 cents.

Costco credit card FAQ

What credit cards does Costco Canada accept in store?

Costco exclusively accepts Mastercard branded credit cards at their warehouses in Canada. Surprisingly, in the USA, they exclusively take Visa and not Mastercard. Costco also accepts debit cards for payment.

What credit cards does Costco Canada accept online?

Shopping online at is not the same as shopping in-store. For online purchases, Costco accepts both Mastercard and Visa credit cards. That said, Costco no longer accepts American Express cards – even online.

Is the Capital One Costco credit card a good deal?

The Capital One Costco Mastercard exclusively for Costco members isn’t a bad deal because it gives you decent rewards for a no fee credit card and doubles as your Costco membership card reducing the clutter in your wallet.

On the flip side, you’ll only earn between 0.5% and 1% on your Costco purchases. There are credit cards in Canada (both premium and no fee) that can earn you between 1% and 2% cash back on all your purchases anywhere, including Costco. With the Costco Mastercard, you’re also locked into redeeming your “cash” rewards in-store, whereas other cards let you get your cash as a statement credit or even a cheque or direct deposit.

Does Costco count as a grocery store?

Many credit cards offer more rewards on grocery store purchases and many Canadians consider Costco to be a grocery store. Unfortunately, Costco is not categorized as a grocery store by the Mastercard network and therefore purchases made there are not eligible for grocery bonuses. In fact, there is no credit card bonus spending category that Costco qualifies for at all.
