Always confirm current terms and conditions on the issuer’s official website before applying for any credit card. Consider your own financial situation carefully before making any credit decision.
Costco only accepts Visa cards at its U.S. warehouse locations — a policy that immediately eliminates Mastercard, Amex, and Discover from the in-store equation. This makes the credit card decision for Costco shoppers more focused than most: which Visa card earns the best rewards on your Costco purchases, and is the Costco co-branded card actually the best option or just the most obvious one?
The answer is nuanced. The Costco Anywhere Visa Card by Citi earns 5% at Costco gas stations and 4% on gas elsewhere — among the highest gas rates available — but earns only 2% on in-store Costco purchases. For a household spending $500/month inside Costco warehouses, a flat 2% card like the Wells Fargo Active Cash earns the same 2% with a much easier welcome offer and no Costco-specific redemption restrictions. Meanwhile, for non-Costco spending categories like dining and gas, the Costco Anywhere Visa’s 3% on restaurants and 4% on outside gas make it genuinely excellent beyond the warehouse walls.
The right Costco credit card strategy in 2026 depends on where you spend most: inside Costco (where any 2% Visa ties the co-branded card), at Costco gas stations (where the co-branded card wins at 5%), or split across both Costco and other everyday categories (where pairing two cards may earn more than any single card). This guide covers all five options with data verified from issuer websites as of August 2026.
Best Credit Cards for Costco 2026 — At a Glance
| Card | Best For | Annual Fee | In-Store Costco Rate | Costco Gas Rate | Visa? |

| Wells Fargo Active Cash | Best flat 2% on all Costco purchases, no restrictions | $0 | 2% | 2% | ✅ Visa |
| Chase Freedom Unlimited | Best for Costco + dining + drugstore combo | $0 | 1.5% | 1.5% | ✅ Visa |
| Capital One Venture X | Best premium Visa for Costco + travel rewards | $395 | 2x miles | 2x miles | ✅ Visa |

How We Ranked These Cards
CardRankr’s editorial team evaluated each card using five criteria specific to Costco shopping. No card issuer paid for placement or influenced our rankings.
- Visa network acceptance: Only Visa cards work at Costco U.S. warehouse locations. Every card on this list is Visa — the baseline requirement for in-store Costco use.
- In-store Costco earn rate: The cash back or rewards percentage earned on warehouse purchases and Costco.com. Most cards earn their standard rate since Costco is typically coded as a wholesale club or general merchandise retailer.
- Costco gas station earn rate: Costco gas stations are among the cheapest in most markets — the earn rate there is a separate and important consideration for households that fuel up at Costco regularly.
- Non-Costco earn rate: Since most cardholders use their card beyond Costco, the card’s rewards on dining, travel, and everyday spending matter for total annual value.
- Redemption flexibility: How and when you can access your rewards — the Costco Anywhere Visa’s annual certificate redemption model is a significant limitation compared to cards offering instant cash back or statement credits.
The 5 Best Cards for Costco: Full Reviews
1. Costco Anywhere Visa Card by Citi — Best Overall for Costco Members
| Annual fee | $0 (requires active Costco membership — Gold Star $65/yr, Executive $130/yr) |
| Welcome offer (Aug 2026) | None publicly advertised at this time |
| Top rewards | 5% at Costco gas stations worldwide · 4% other eligible gas + EV charging (up to $7,000/yr combined, then 1%) · 3% restaurants + eligible travel · 2% Costco and Costco.com · 1% all other · No foreign transaction fee |
The Costco Anywhere Visa Card by Citi is the natural first card to consider for any Costco member — and it earns its position honestly, though not without important caveats. Its headline benefit is the gas earn rate: 5% at Costco-branded gas stations and 4% at all other eligible gas stations and EV charging (up to $7,000/year combined). For a household fueling up twice a week at Costco gas — typically $80–$120 per fill-up for a full-size SUV — the 5% rate generates $200–$300 per year from gas alone. That is the highest gas earn rate of any card at Costco locations, and competitive with the best gas cards in the broader market.
The 3% on restaurants and eligible travel makes the Costco Anywhere Visa genuinely useful beyond the warehouse walls. A household spending $500/month on dining earns $180/year at 3% from that category. The card becomes most valuable when viewed as a full household card — not just a Costco card — covering gas, dining, travel, and Costco purchases across a single Visa that is accepted everywhere Visa is.
The critical caveat is the in-store Costco earn rate: 2%. That is competitive with flat-rate no-fee cards but not exceptional — you earn the same 2% from the Wells Fargo Active Cash on every Costco warehouse purchase. For Executive members, Costco itself pays an additional 2% Executive Reward on purchases, which stacks with the card’s 2% for an effective 4% on in-store Costco purchases — a meaningful benefit that makes the Costco card significantly more valuable for Executive-level members than Gold Star members.
The most significant limitation of the Costco Anywhere Visa is its redemption structure. Rewards do not post as flexible cash back — they accumulate throughout the year and are paid once annually in February as a Costco reward certificate. That certificate must be redeemed in person at a Costco warehouse location or Costco.com — it cannot be deposited to a bank account or applied as a statement credit. For cardholders who shop at Costco regularly, this is a minor inconvenience. For those who move or stop their membership before February, it can mean forfeiting rewards.
Who it’s for: Active Costco members — especially Executive members — who fill up at Costco gas stations regularly and also use the card for dining and travel outside Costco. The card delivers the most value to households where gas (5%), restaurants (3%), and regular Costco shopping (2% + Executive 2%) all run through the same card. Requires excellent credit — FICO 720 or above for the best approval odds.
Watch-outs: No welcome bonus — a significant disadvantage versus competitors. Rewards only accessible once per year as a Costco certificate, not flexible cash. The 2% on in-store Costco purchases is matched by flat-rate cards with better redemption options. The $7,000 annual cap on the 4–5% gas rate may be a real constraint for households with multiple vehicles or very high gas spend. Gas earned at superstores, supermarkets, and convenience stores earns only 1%.
2. Wells Fargo Active Cash Card — Best Flat 2% on All Costco Purchases
| Annual fee | $0 |
| Welcome offer (Aug 2026) | $200 cash rewards after $500 spend in 3 months |
| Top rewards | 2% cash rewards on all purchases (unlimited, no categories, no caps) · Cell phone protection ($600/claim, $25 deductible) · No foreign transaction fee · Visa network |
The Wells Fargo Active Cash earns 2% on every Costco purchase — in-store, Costco.com, gas, pharmacy, food court, optical — with no categories, no caps, and no annual redemption restrictions. Where the Costco Anywhere Visa earns 2% on warehouse purchases but locks rewards in an annual certificate, the Active Cash earns the same 2% as flexible cash rewards redeemable anytime as statement credits, direct deposit, or ATM withdrawal. For households who primarily shop inside Costco warehouses rather than at Costco gas stations, the Active Cash delivers the same in-store earn rate with significantly more redemption flexibility.
The $200 welcome offer after just $500 in spending — achievable in a single Costco run — is a meaningful first-year advantage over the Costco Anywhere Visa, which typically offers no welcome bonus. Cell phone protection ($600 per claim, $25 deductible) adds practical value. For Executive Costco members, the Active Cash’s 2% stacks with the Executive’s own 2% reward — same as the Costco card — making the Active Cash equally effective for in-store Costco shopping for Executive members, with better redemption flexibility. For a full comparison of the Active Cash as an everyday card, see our guide Best Cash Back Credit Cards of 2026: Top 7 Picks Compared.
Who it’s for: Costco members who do most of their Costco spending inside the warehouse (not primarily at Costco gas) and want instant, flexible cash back rather than an annual Costco certificate. Also the best card for Costco members who don’t fill up at Costco gas — the Costco Anywhere Visa’s gas advantage doesn’t apply if you fill up elsewhere.
Watch-outs: The 2% flat rate does not beat the Costco card’s 5% at Costco gas stations — if you fill up at Costco regularly, the co-branded card earns more on gas. No bonus categories — dining, travel, and other spending all earn the same 2% with no premium earn potential.
3. Chase Freedom Unlimited — Best for Costco + Dining + Everyday Spending
| Annual fee | $0 |
| Welcome offer (Aug 2026) | $200 cash back after $500 spend in 3 months |
| Top rewards | 5% Chase Travel · 3% dining worldwide and drugstores · 1.5% all other purchases including Costco · Primary rental car CDW · 0% intro APR 15 months |
The Chase Freedom Unlimited earns 1.5% on Costco warehouse purchases — below the 2% of the Active Cash and Costco Anywhere Visa for in-store Costco spending. However, for households where Costco is just one of many spending categories, the Freedom Unlimited’s 3% on dining worldwide and 1.5% floor on everything else can generate more total annual rewards than a flat 2% card, depending on dining spend. A household spending $500/month at Costco (1.5% = $90/year) and $600/month on dining (3% = $216/year) earns $306/year from those two categories on the Freedom Unlimited — versus $264/year at 2% flat on the same combined spending.
The Freedom Unlimited’s primary rental car CDW coverage and 0% intro APR on purchases for 15 months add meaningful utility beyond rewards. As part of the Chase Ultimate Rewards ecosystem, it pairs naturally with a Sapphire Preferred or Reserve to unlock airline and hotel transfer partners. For a comparison of the Freedom Unlimited against other Chase no-fee options, see our article Chase Freedom Unlimited vs. Chase Freedom Flex (2026): Which Card Wins?
Who it’s for: Costco members who also spend heavily on dining and want a single no-fee Visa that earns competitively across Costco, restaurants, and everyday spending — with the option to build Chase Ultimate Rewards points for travel.
Watch-outs: The 1.5% on Costco purchases trails the 2% of the Active Cash and Costco card for in-store warehouse spending. A 3% foreign transaction fee applies. Chase’s 5/24 rule: five or more new card accounts in 24 months typically results in denial.
4. Capital One Venture X — Best Premium Visa for Costco + Travel
| Annual fee | $395 (effective ~$0 after $300 travel credit + 10K anniversary miles) |
| Welcome offer (Aug 2026) | 75,000 miles after $4,000 spend in 3 months (~$1,350 at TPG valuations) |
| Top rewards | 2x miles on all purchases including Costco · 10x hotels + rental cars via C1 Travel · 5x flights via C1 Travel · Priority Pass + Capital One Lounges · No foreign transaction fee · Visa network |
The Capital One Venture X earns 2x miles on every Costco purchase — in-store, Costco.com, gas, and all other spending — with no caps and no annual certificate redemption structure. Miles are immediately accessible, transferable to 15+ airline partners, and usable through the Capital One Travel portal. For Costco-shopping frequent travelers who want a premium card that works universally at Costco (Visa) and everywhere else, the Venture X is the strongest all-in-one option at the $395 annual fee tier.
The $300 Capital One Travel credit and 10,000 anniversary miles together offset $400 of the annual fee — bringing the effective cost to approximately $0 for active travelers. Priority Pass Select (1,300+ lounges globally) and Capital One Lounge access add substantial travel value on top of the Costco earn rate. For a full standalone review, see our article Is the Capital One Venture X Worth It? (2026 Honest Review).
Who it’s for: Costco members who also travel frequently and want a premium card that earns 2x miles on all Costco spending (redeemable for flights and hotels) alongside lounge access and travel credits. The best single card for the frequent-traveler Costco household.
Watch-outs: The $395 annual fee requires meaningful travel to justify via credits and lounge access. Capital One pulls all three credit bureaus at application.
5. U.S. Bank Smartly Visa Signature Card — Best for U.S. Bank Customers
| Annual fee | $0 |
| Welcome offer (Aug 2026) | Varies — check usbank.com for current offer |
| Top rewards | 2% on all purchases baseline · Up to 4% on all purchases for Smartly members with $100,000+ in U.S. Bank accounts · Visa network · No foreign transaction fee |
The U.S. Bank Smartly Visa Signature is the most powerful Costco card for existing U.S. Bank customers with significant deposits. Its base rate of 2% on all purchases — including all Costco warehouse purchases — matches the Costco Anywhere Visa and Active Cash. But for U.S. Bank Smartly members with $100,000 or more across eligible U.S. Bank accounts, the earn rate boosts to 4% on all purchases with no category restrictions and no caps. At 4% on Costco warehouse spending, it outperforms every other card on this list for in-store Costco purchases — including the Costco Anywhere Visa’s 2% on warehouse shopping.
Even at the more accessible $10,000 deposit threshold, the Smartly earns 2.5% — still ahead of the Costco card’s 2% on warehouse purchases. For existing U.S. Bank customers who shop at Costco regularly and maintain meaningful deposits, the Smartly is the best flat-rate Visa for Costco that requires no Costco membership-specific commitment and offers fully flexible cash redemptions.
Who it’s for: Existing U.S. Bank customers with $10,000+ in eligible accounts who want a flexible high-rate Visa for Costco and all other spending. The best card for heavy in-store Costco shoppers who don’t primarily fill up at Costco gas.
Watch-outs: The enhanced earn rates require maintaining significant U.S. Bank deposit balances. At the baseline (under $10,000 in deposits), the card earns only 2% — equal to the Active Cash and Costco card on warehouse purchases, with no advantages. Approval odds are strongest for existing U.S. Bank customers.

How to Choose Your Costco Credit Card Strategy
If you fill up at Costco gas regularly — get the Costco Anywhere Visa
The co-branded card’s 5% at Costco gas stations is its clearest, most unambiguous advantage. A household filling two vehicles weekly at Costco gas, spending $400/month total, earns $240/year from gas alone at 5% — versus $96 on the same spending at a flat 2% card. If Costco gas is a regular habit, the Costco Anywhere Visa pays for itself through gas rewards alone, regardless of the annual certificate redemption structure.
If you primarily shop inside the warehouse — consider the Active Cash instead
The Costco Anywhere Visa earns only 2% on in-store purchases — identical to the Wells Fargo Active Cash’s flat rate. If your Costco spending is warehouse-focused rather than gas-focused, the Active Cash earns the same on your primary Costco category with better redemption flexibility (anytime, any amount, as cash) and a $200 welcome offer the Costco card doesn’t offer. The Active Cash is the better card for warehouse-dominant Costco shoppers.
The optimal two-card strategy for heavy Costco users
The highest-earning setup for heavy Costco members: Costco Anywhere Visa for gas (5% Costco, 4% elsewhere) and dining (3%). Wells Fargo Active Cash for all in-store Costco warehouse purchases and all other spending (2% flat). This two-card approach earns more total annual rewards than either card alone — the Costco card handles its best categories at maximum rates, the Active Cash captures everything else at 2% with instant flexible redemptions. Combined annual fee: $0 (plus Costco membership you’d have regardless).
Remember: Costco only accepts Visa in-store
This is the non-negotiable constraint of the entire comparison. Mastercard, American Express, and Discover are not accepted at U.S. Costco warehouse locations. All five cards on this list are Visa — but if you are considering any other card for Costco spending, confirm it runs on Visa before applying. Costco.com accepts all major credit cards, so non-Visa cards can be used for online Costco purchases only.
Frequently Asked Questions
What is the best credit card to use at Costco in 2026?
For most Costco members, the best single card is the Costco Anywhere Visa by Citi — earning 5% at Costco gas stations, 4% on other eligible gas and EV charging, 3% at restaurants and eligible travel, and 2% on all Costco warehouse purchases. For members who don’t fill up at Costco gas regularly, the Wells Fargo Active Cash (2% flat, instant cash redemption, $200 welcome offer) is the better choice for in-store Costco shopping. For heavy Costco users who also travel, the Capital One Venture X ($395, effective ~$0 after credits) earns 2x miles on all Costco purchases with no category restrictions.
Does Costco accept Mastercard, Amex, or Discover?
No — Costco U.S. warehouse locations only accept Visa credit cards, along with cash, debit cards, EBT, and Costco Shop Cards. Mastercard, American Express, and Discover are not accepted in Costco stores. Costco.com does accept Visa, Mastercard, and Discover for online orders. If you hold a non-Visa rewards card, you can only earn rewards on Costco purchases made online, not in-store.
Is the Costco Anywhere Visa worth it in 2026?
Yes — for members who regularly fill up at Costco gas stations and use the card for dining and travel. The 5% at Costco gas and 4% on other gas represent the highest gas earn rates of any widely available general-purpose card, and the 3% on restaurants is competitive with the best dining cards. The card becomes less compelling if you don’t fill up at Costco gas (the in-store 2% is matched by flat-rate cards) and if the annual certificate redemption structure doesn’t fit your habits. For Executive Costco members, the additional 2% Executive Reward stacks with the card’s 2% for 4% on in-store purchases, significantly increasing its value.
What credit score do I need for the Costco Anywhere Visa?
The Costco Anywhere Visa by Citi requires excellent credit — most approved applicants have a FICO score of 720 or above. This is a higher bar than most other cards on this list. The Wells Fargo Active Cash and Chase Freedom Unlimited require good to excellent credit (670+). The Capital One Venture X requires excellent credit (720+) and Capital One pulls all three credit bureaus at application. The U.S. Bank Smartly requires good to excellent credit with stronger odds for existing U.S. Bank customers.
Can I use a non-Visa credit card at Costco?
Not in-store. Costco U.S. warehouse locations accept only Visa credit cards. Non-Visa cards (Mastercard, Amex, Discover) can be used at Costco.com for online purchases. If your primary rewards card is a Mastercard or Amex, you have two options: use a Visa debit card in-store (no rewards), or carry a separate Visa credit card specifically for Costco in-store purchases while using your preferred card for Costco.com orders.
Does the Costco Anywhere Visa earn 5% on all gas?
No — the 5% rate applies only to gas purchased at Costco-branded gas stations. All other eligible gas stations earn 4% (not 5%). Both the 5% Costco gas rate and 4% other gas rate apply to a combined $7,000 cap per year, then drop to 1%. Additionally, gas purchases at superstores, supermarkets, convenience stores, and non-Costco warehouse clubs earn only 1%.
