Costco Citi Card Benefits and Cash Back Explained
The Costco Citi Card gives Costco members a simple way to earn cash back on everyday spending.
It offers 5% back on gas at Costco, 4% at other gas and EV charging stations, 3% on restaurants and travel, 2% at Costco and Costco.com, and 1% on everything else.
This is a pretty good deal if you shop at Costco and want rewards without paying extra fees beyond your Costco membership.
No foreign transaction fees here, so it works well for travel too. But just a heads-up: that 5% back on gas only applies to the first $7,000 per year (combined with the 4% gas and EV rate), and rewards show up as an annual coupon you can use at Costco.
Knowing these quirks helps you figure out if the card fits your budget and shopping style. All rates and fees below are current as of July 2026.
How the Costco Citi Card Works
The Costco Citi Card keeps things pretty straightforward. You’ll need an active Costco membership and can apply through Citi with a quick online form or a phone call.
The card doubles as your Costco membership ID. That means you can use it for both paying and verifying your membership at checkout, which is honestly pretty convenient. It’s also worth knowing Costco only takes Visa at the register, so this card sidesteps that limit built right in.
Eligibility and Application Process
You have to be at least 18 and meet Citi’s credit requirements. They’ll look at your credit score, income, and payment history.
Approval is usually fast, and once you’re in, you can start racking up rewards right away. There’s no extra annual fee for the card, but you do have to keep your Costco membership active to keep the benefits coming.
Linking Your Card to Your Costco Membership
Your Costco Citi Card is automatically linked to your membership. Using it at Costco or on Costco.com ties your purchases to your account without any extra steps.
Add authorized users if you want your family to earn cash back too. It’s all tracked under one account, which keeps things tidy.
Using the card with your membership lets you tap into perks like digital wallet compatibility and purchase protection.
Cash Back Rewards Structure
The Costco Anywhere Visa® Card by Citi splits cash back into five tiers. You’ll get the best rewards for gas, dining, travel, and Costco shopping.
| Purchase category | Cash back |
|---|---|
| Gas at Costco | 5% |
| Other gas and EV charging | 4% |
| Restaurants and eligible travel | 3% |
| Costco and Costco.com | 2% |
| Everything else | 1% |
5% Cash Back at Costco Gas Stations
With this card, you get 5% cash back on gas at Costco gas stations. That’s one of the highest rates you’ll find for gas anywhere.
➤ The 5% applies only to gas bought at Costco, and it shares a $7,000 yearly cap with the 4% gas and EV rate. After you hit $7,000 combined, you drop to 1% on gas.
4% Cash Back on Eligible Gas and EV Charging
For gas and EV charging outside of Costco, you get 4% cash back. This rate counts toward the same combined $7,000 yearly cap as your Costco gas.
Once you hit that limit, it’s back to 1% for the rest of the year. So if you drive a lot or have an EV, you can still get decent rewards even when you’re not at Costco. For most drivers, $7,000 a year is roughly $135 a week in fuel, so you’d have to fill up hard to max it out.
3% Cash Back on Restaurants and Travel
Dining out or booking travel? You’ll get 3% cash back at restaurants and on eligible travel, including bookings through Costco Travel.
This covers all sorts of travel expenses, think airfare, hotels, car rentals, and cruises. Eating out and traveling can add up, so this perk is nice if you do either regularly. Unlike the gas rate, the 3% has no annual cap.
2% and 1% Cash Back on Costco and Everyday Purchases
Shopping at Costco gets you 2% cash back on everything else. That goes for groceries, electronics, household goods, and more.
Sign-Up Bonus
The Costco Anywhere Visa has no sign-up bonus as of July 2026. There’s no spending target to hit and no welcome offer, so don’t apply expecting a chunk of intro rewards.
The value here is all in the ongoing cash back, not a one-time carrot. If a welcome bonus is what you’re after, a different card will serve you better, but few of those can be used at the Costco register.
Redeeming Costco Cash Rewards
Cash back from your Costco Citi Card comes as an annual certificate. You can redeem it at Costco warehouses for cash or merchandise, or direct-deposit it to your bank if it’s $300 or more.
Annual Reward Certificate Process
Every February, you’ll get a reward certificate when your billing statement closes. It totals up everything you earned in the past year.
Certificates are sent by mail, email (if you’re paperless), or you can grab it from the Citi app. You’ll need to keep your Costco membership active and the card open to get your rewards.
➤ Certificates expire December 31st of the year they’re issued, so use them before the year’s up. Wouldn’t want to lose out just because you forgot.
Redemption at Costco Warehouses
To redeem in person, bring the original certificate to a Costco warehouse in the U.S., including Puerto Rico. Hand it in at the membership counter or register, and you can put it toward merchandise or ask for cash.
If your certificate is $300 or more, you can skip the trip and direct-deposit it to a bank account through Citi.com or the Citi app. Anything under $300 has to be redeemed at a warehouse, since the direct-deposit option won’t even show up in your account.
One thing people mix up: this Citi certificate is separate from the Costco Executive 2% reward. If you have an Executive membership, you get both, and they don’t affect each other.
Key Cardholder Benefits
The Costco Citi Card comes with some helpful protections and perks. You’ll feel a bit more secure when shopping or traveling, and you can skip some of those annoying extra fees.
Purchase Protection Coverage
There’s damage and theft purchase protection on new items, covering you for 120 days after you buy (90 days if you live in New York). If something is damaged or stolen in that window, you might get repairs or reimbursement.
There are limits per claim and per year, so check the fine print. If you need to make a claim, hang onto your receipts and act fast.
No Foreign Transaction Fees
Travelers will like that there are no foreign transaction fees with this card. That’s 3% saved on every overseas purchase compared to many other cards.
It’s also handy if you shop on international websites. You just pay the purchase price, no hidden extras.
Travel and Emergency Assistance
The card gives you access to travel and emergency assistance services. If you need help with medical referrals, legal stuff, or urgent travel arrangements, you’ve got someone to call.
They don’t cover the service costs, but they’ll connect you to the right people. It’s available 24/7, which is reassuring when you’re far from home.
Car Rental Insurance and Added Perks
When you rent a car and pay with this card, you get car rental insurance for damage or theft. That means you can skip the rental agency’s insurance and save some cash.
This usually works for most rentals, whether you’re traveling for work or fun. Just remember to decline the agency’s collision coverage to use it.
You might also get roadside assistance and extended warranty protection. These little extras can add up in value over time.
Costs, Fees, and Important Terms
The Costco Citi Card has a few costs and terms you’ll want to know about, like interest rates, fees, and payment rules. Here’s the quick version, current as of early 2026.
| Fee or rate | Amount |
|---|---|
| Purchase APR (variable) | 18.74% to 26.74% |
| Cash advance APR (variable) | 28.74% |
| Penalty APR | up to 29.99% |
| Foreign transaction fee | None |
| Cash advance fee | $10 or 5%, whichever is greater |
| Balance transfer fee | $5 or 5%, whichever is greater |
| Annual fee | $0 with paid Costco membership |
Variable APR and Interest Charges
The card has a variable APR that shifts with market conditions and your credit profile. As of early 2026, purchases run 18.74% to 26.74%, and the rate covers balance transfers and Citi Flex Plans too.
If you miss a payment or one bounces, you might get hit with a penalty APR of up to 29.99%. Interest starts piling up daily on any balance you don’t pay off by the due date, and there’s a minimum charge of $0.50 even when the math is tiny.
No extra fees for foreign transactions, which is a nice perk if you travel. You’ll see your exact APR when you apply, and honestly, those rates can swing a bit.
Balance Transfers and Cash Advances
Balance transfers come with a fee of $5 or 5% of what you move, whichever is more. It’s tempting to consolidate debt, but those costs add up if you’re not careful.
➤ Cash advances work about the same, except pricier. The APR is 28.74%, the fee is $10 or 5% whichever is greater, and interest starts right away with no grace period.
Pulling cash from your card is expensive, so it’s best saved for real emergencies. Most folks try to avoid it unless there’s no other option.
No Annual Fee Requirement
This card doesn’t charge an annual fee, aside from the paid Costco membership. A Gold Star membership runs $65 a year as of July 2026, and the Executive tier costs more but adds that separate 2% reward.
The card itself has no extra yearly charge. It’s a pretty simple deal for Costco members, honestly.
Cardholders do need to keep their Costco membership active to use the card. If your membership lapses, the card stops working and you’d lose out on the perks.
Is the Costco Citi Card Worth It
For anyone who already pays for a Costco membership, the card is worth it since it costs nothing extra and the 2% back at Costco alone pays for itself fast. The gas and dining rates are where it really earns its keep.
My honest take: the once-a-year payout is the real catch. If you want cash back hitting your account every month, this isn’t your card. But if you can wait until February for a lump sum and you shop Costco anyway, few cards beat it, and it verifies your membership at checkout as a bonus.
