The Costco Visa card gives you cash back on purchases, extended warranties on may be able to access items, and travel protections — but the rewards structure and coverage limits depend on where you shop and what you buy

The Costco Visa is a co-branded card issued by Citi, available only to Costco members. It earns cash back at different rates depending on the category: 4% at Costco gas stations and Costco.com, 3% at Costco warehouses, 2% on travel (including flights, hotels, rental cars, and parking), and 1% everywhere else. The cash back posts as an annual reward certificate to your Costco account, not as a statement credit or direct deposit.

The card also includes purchase protections, extended warranties, and travel benefits that are built into the card itself — you do not pay extra for these. Understanding what is actually covered, and what is not, matters because the limits are real and the exclusions are specific.

Key Takeaways

  • Cash back is paid as an annual Costco reward certificate, not as cash or a statement credit, and you must have an active Costco membership to use it.
  • The 4% rate applies only at Costco gas stations and Costco.com; in-warehouse purchases earn 3%, and the 1% category is everything outside Costco.
  • Extended warranty coverage doubles the manufacturer's warranty up to a maximum of five additional years, but excludes items like cars, boats, and items used for business.
  • Travel accident insurance covers emergency medical and dental expenses while traveling, but only if the trip was charged to the card and the coverage limits are modest.
  • The card has no annual fee, but you must maintain an active Costco membership to hold it.

How the cash back reward works

The Costco Visa does not deposit cash back into your bank account or credit your statement. Instead, Citi calculates your annual cash back total and issues it as a Costco reward certificate. This certificate appears in your Costco account and can be used like a gift card at any Costco warehouse or on Costco.com. The certificate is valid for one year from the issue date.

The cash back rate varies by where you use the card. At Costco gas stations and Costco.com, you earn 4%. Inside Costco warehouses, you earn 3%. On travel purchases — flights, hotels, rental cars, parking, and tolls — you earn 2%. Everything else earns 1%. The card does not offer bonus categories outside these four, and there is no sign-up bonus.

If you let your Costco membership lapse, you lose access to the reward certificate, even if you still hold the card. This is a real constraint if you are considering downgrading your membership or taking a break from shopping there.

Purchase protection and extended warranty coverage

The Costco Visa includes purchase protection that covers items you buy with the card against damage or theft for 120 days from the purchase date. The coverage limit is $10,000 per claim and $50,000 per account per year. This is useful for high-value purchases, but the 120-day window is shorter than some competitors offer.

Extended warranty coverage doubles the manufacturer's warranty on may be able to access items, up to a maximum of five additional years. So if an item comes with a one-year warranty, the card extends it to two years; a two-year warranty becomes four years. The maximum total coverage is five years from the original purchase date. This applies to appliances, electronics, and most household goods, but excludes cars, boats, jewelry, art, items used for business, and items with a manufacturer's warranty longer than five years.

To use extended warranty coverage, you typically need to register the item with Citi and provide proof of the original manufacturer's warranty. The process is straightforward but requires you to keep your receipt and the warranty documentation.

Travel protections and emergency medical coverage

The card includes travel accident insurance that covers emergency medical and dental expenses if you are injured or become ill while traveling more than 100 miles from home. The coverage limit is $250,000 for medical expenses and $500 for dental. The trip must be charged to the Costco Visa for the coverage to explore, and the coverage is secondary — it pays after your health insurance.

The card also includes trip cancellation and trip interruption insurance. If you cancel a prepaid trip for a covered reason (illness, injury, or death of a family member), or if your trip is interrupted by one of these events, the card reimburses prepaid, non-refundable costs up to $10,000 per person and $20,000 per trip. Again, the trip must have been charged to the card.

Lost luggage reimbursement covers baggage and personal belongings lost or damaged by a carrier, up to $2,500 per person. You must report the loss to the carrier and file a claim with Citi within a set timeframe, usually 90 days.

What the card does not cover

The extended warranty does not explore to items used for business purposes, even if you use them occasionally. It also does not cover items with a manufacturer's warranty longer than five years, jewelry, art, antiques, or items purchased secondhand. Vehicles, boats, and motorized equipment are excluded entirely.

The travel protections require that the trip or the specific expense be charged to the Costco Visa. If you book a flight with the card but pay for the hotel with a different card, the hotel is not covered under trip cancellation insurance. This matters if you split payments across multiple cards.

The card has no rental car damage waiver, no roadside information, and no concierge service. If you are comparing it to premium travel cards, those gaps are worth noting.

Annual fee and membership requirements

The Costco Visa has no annual fee. However, you must maintain an active Costco membership to hold the card. Costco membership costs $60 per year for a Gold Star membership or $120 per year for an Executive membership. If your membership lapses, Citi will close the card.

This is different from most credit cards, which do not require membership in a separate organization. It means the true cost of the card is the membership fee, not the card itself. If you are already a Costco member, the card adds no cost. If you are not, you need to factor in the membership fee when deciding whether the rewards are worth it.

Comparing the cash back to other cards

The 4% cash back at Costco gas and Costco.com is competitive with other premium cards, but the 3% in-warehouse rate is lower than some alternatives. The American Express Blue Business Plus, for example, offers 3% cash back on internet, cable, and phone services, and some cards offer 3% or higher on groceries or gas outside Costco.

The 2% on travel is standard but not exceptional. Many cards offer 2% or higher on travel, and some offer higher rates if you book through their travel portal. The 1% catch-all category is below average — most cards offer 1.5% or higher on everything.

The real advantage of the Costco card is the combination of rewards, protections, and the fact that there is no annual fee. If you spend heavily at Costco and use the card for travel, the 4% and 2% rates add up. If you shop elsewhere most of the time, a different card may earn you more.

How to use the reward certificate

Your annual cash back reward certificate is issued once per year and appears in your Costco account online or in the Costco app. You can use it at any Costco warehouse or on Costco.com. The certificate is treated like a gift card — you scan it or enter the number at checkout, and the balance is deducted from your purchase.

The certificate is valid for one year from the issue date. If you do not use it within that year, it expires and you lose the balance. Costco does not roll over unused balances or issue refunds, so marking the expiration date on your calendar is worth doing if you receive a large certificate.

If you close your Costco membership, any unused reward certificate becomes invalid. This is another reason to keep your membership active if you have a pending certificate balance.

Frequently Asked Questions

Can I get cash back instead of a Costco reward certificate?

No. The Costco Visa only issues cash back as a Costco reward certificate. You cannot request a direct deposit, statement credit, or check. If you prefer cash back in your bank account, a different card would be a better fit.

Does the extended warranty cover accidental damage?

No. Extended warranty coverage protects against manufacturer defects and mechanical failure, not accidental damage. If you drop an item or spill liquid on it, the extended warranty does not cover the repair or replacement.

What happens to my card if I downgrade my Costco membership?

Citi will close your Costco Visa if your membership lapses. You can reopen the card if you renew your membership, but you will need to reapply. Any unused reward certificate will expire when your membership ends.

Does the 2% travel rate include booking through Costco Travel?

Yes. Purchases through Costco Travel, which offers discounted vacation packages and travel services, earn the 2% travel rate. You must be a Costco member to use Costco Travel.

Is the card worth it if I only shop at Costco occasionally?

That depends on your membership tier and how much you spend elsewhere. If you have a Gold Star membership ($60 per year) and spend less than $1,500 annually at Costco, the 3% cash back may not cover the membership cost. An Executive membership ($120 per year) includes a 2% annual reward on all Costco purchases, which can offset the higher fee if you spend more.
