How the Citi Costco Credit Card Works and Costs

Overview of the Citi Costco Credit Card

The Citi Costco Credit Card is a co-branded rewards card issued by Citibank in partnership with Costco Wholesale. This card works primarily as a shopping tool for Costco members who want to earn rewards on their purchases. The card functions like a standard credit card—you use it to make purchases and pay back what you spend each billing cycle—but it offers special rewards that tie directly to Costco's membership structure.

The card comes in two main versions: the Costco Anywhere Visa Card for Costco members and the Costco Anywhere Visa Card for non-Costco members. However, the most common version requires an active Costco Gold Star membership or Executive membership. Without this membership, you cannot use the card at Costco, though you can use it elsewhere that Visa is accepted.

As of 2024, the card has no annual fee, which distinguishes it from many premium rewards cards on the market. This means you can hold the card without paying membership costs beyond what you already pay to Costco. The card's rewards structure is built around categories of spending, with different earning rates depending on where and how you shop.

The card operates on Visa's payment network, which means it's accepted wherever Visa cards are taken. This is important because it gives you the option to use the card both inside and outside of Costco locations. The rewards you earn are redeposited as Costco Cash—a form of store credit you can use on future Costco purchases or to pay your Costco membership renewal.

Practical Takeaway: Before considering this card, confirm you have or plan to maintain a Costco membership, as the primary rewards benefits center on Costco shopping. The card's main draw is the rewards structure, not convenience features or travel perks.

How the Rewards Program Works

The Citi Costco Credit Card operates on a tiered rewards system where you earn Costco Cash at different rates depending on your spending category. Costco Cash is a certificate of credit that appears in your Costco account and can be used like a store credit toward purchases or membership renewal. It typically expires 12 months from the issue date if unused.

At Costco warehouses, you earn 4% Cash back on eligible gas purchases at Costco gas stations (up to $7,000 per year, then 1% after that). This is one of the highest rates in the rewards program. You earn 3% Cash back on travel purchases made through Costco Travel, which includes airline tickets, hotel bookings, and vacation packages booked directly through Costco's travel platform. You earn 2% Cash back on purchases made at Costco warehouses and on Costco.com.

Outside of Costco, you earn 1% Cash back on all other purchases when using your Visa card at any merchant that accepts it. This baseline rate is modest compared to some other rewards cards but provides value on everyday spending like groceries at non-Costco stores, restaurants, and online shopping outside of Costco.

There is an important cap on the 4% gas rewards: once you've earned rewards on $7,000 in gas purchases in a calendar year, any additional gas purchases earn only 1% Cash back for the remainder of that year. For someone who fills up at Costco frequently, this cap means the 4% rate applies to roughly the first 50-70 fill-ups depending on tank size, then drops to 1%.

The rewards are not points—they're actual cash rewards that reduce the amount of money you need to spend at Costco. A $100 purchase at Costco warehouse with a 2% reward generates $2 in Costco Cash, which you can then apply to a future transaction or membership renewal.

Practical Takeaway: Calculate your expected spending to understand whether this card's rewards rates match your shopping patterns. The 4% gas rate is most valuable, but the $7,000 cap limits its benefit for high-volume gas purchasers.

Costs, Fees, and Annual Terms

The Citi Costco Credit Card carries no annual fee, which is significant in the credit card market where many premium rewards cards charge $95 to $550 per year. This means you can keep the card active indefinitely without paying a membership cost beyond your regular Costco warehouse membership.

However, there are several other fees to understand. If you make a purchase and don't pay your full balance by the due date, you'll pay interest on the remaining balance. The card's current annual percentage rate (APR) for regular purchases varies based on your creditworthiness but typically ranges from 18% to 28% depending on the market environment and your credit profile. This is important to understand because carrying a balance makes the rewards you earn worth significantly less than the interest you'll pay.

There are late payment fees if your payment arrives after the due date. As of 2024, Citibank charges up to $40 for a late payment. There are also penalty APR increases—if you make a late payment, your interest rate may increase to a higher penalty rate. Foreign transaction fees apply when you use the card outside the United States; typically this is 1% of the purchase amount in foreign currency.

Balance transfer fees, if you transfer debt from another card to this Costco card, are usually 3% of the transferred amount (with a minimum fee, often $5). Cash advance fees apply if you use the card to withdraw cash from an ATM—this is typically 3% of the amount withdrawn or a minimum amount like $2, whichever is greater. It's important to note that cash advances typically accrue interest immediately without a grace period.

There are also returned payment fees (around $40) if a check or automated payment bounces. Additionally, over-the-limit fees may apply if you exceed your credit limit, though these have become less common as card issuers moved toward declining transactions that would exceed limits.

Practical Takeaway: The zero annual fee is the card's main cost advantage. To make this card financially worthwhile, pay your full balance each month to avoid interest charges that would quickly erase any rewards earned.

Comparing the Costco Card to Competitor Cards

Several other credit cards target Costco shoppers or general warehouse club members, and understanding how the Costco card compares helps determine if it's the right choice for your spending.

The Capital One Walmart rewards card is comparable in structure—it offers no annual fee and provides rewards at different tiers based on where you shop. The Walmart card offers 5% cash back at Walmart and on Walmart.com, 2% at gas stations and restaurants, and 1% elsewhere. For Walmart shoppers, this beats the Costco card's rates. However, for Costco members, the Costco card's higher rates inside Costco warehouses make it more valuable at that specific retailer.

The Chase Sapphire Preferred is a premium travel and shopping rewards card with a $95 annual fee. It offers 5x points per dollar on travel booked through Chase and 2x points on dining and other travel-related purchases. It earns 1x point on other spending. This card appeals to frequent travelers but costs money annually and offers no special warehouse shopping rewards. For someone who shops at Costco but doesn't travel frequently, the Costco card's zero annual fee advantage is substantial.

The American Express Blue Cash card offers 3% cash back at US gas stations and transit, 1% at US supermarkets, and 1% on everything else. There's no annual fee. For someone who buys gas at multiple places (not just Costco), the Amex Blue might be competitive. However, Amex cards are not accepted at Costco warehouse locations, so if most of your shopping is at Costco, this card can't help you earn rewards there.

The key differentiator for the Costco card is that the 2% reward at Costco warehouses (where large purchases are common) combines with the 4% gas reward to create high total cash back for Costco-focused households. For households that spend $5,000 per year at Costco warehouse and $3,000 on Costco gas, the Costco card generates $140 in rewards ($100 at 2% + $40 at 4
