In a strategic move that comes at an opportune time for budget-conscious shoppers, Costco has officially launched its partnership with Affirm, giving members a new way to finance larger purchases through flexible payment plans.

The collaboration, formally announced by Affirm on May 14, allows Costco.com shoppers to check their eligibility in real time and, if approved, choose payment plans for purchases ranging from $500 to $17,500 — potentially making those big-ticket items more accessible to members watching their spending.

A new payment option when consumers need it most

The timing couldn’t be better. Consumer spending has been slowing across all income levels since January, with the most significant decline among lower-income households.

With economic uncertainty and concerns about rising costs, many shoppers are becoming increasingly cautious with their spending habits, particularly on more expensive items.

“As summer approaches, we’re seeing more consumers turn to Affirm to prepare for the season ahead — whether it’s outdoor entertaining essentials, like a new barbecue or patio furniture, a storage shed, or a new set of appliances,” said Pat Suh, Affirm’s senior vice president of revenue.

Expanding payment flexibility beyond credit card holders

Costco previously offered a buy-now, pay-later option called Flex Pay through its partnership with Citibank, but that service is limited to Costco Anywhere Visa Card members.

The new Affirm partnership broadens this flexibility to all Costco customers, making financing options more widely available across its growing membership base.

This broader accessibility comes as Costco’s paid household membership has grown to 78.4 million, a 6.8% increase compared to last year. The warehouse giant has effectively captured a growing audience that’s willing to pay for warehouse access while still hunting for value.

Meeting evolving payment preferences

Costco appears to be responding to changing consumer payment behaviors, noting in the announcement that the increasing popularity of pay-over-time services influenced its decision to formalize the Affirm partnership.

The warehouse retailer, which had previously mentioned the partnership in a shareholder letter without confirming a launch date, is making a calculated move to maintain its strong performance while helping members navigate uncertain economic times.

Unlike many other retailers facing financial pressures, this partnership represents Costco’s strategic effort to keep members engaged and spending, even as consumers broadly pull back on discretionary purchases.

A balanced approach in uncertain times

Research shows approximately 30% of people have already tried a pay-over-time service. Costco’s partnership with Affirm reflects a thoughtful approach to meeting consumer needs without pushing members toward unnecessary spending.

By offering more payment flexibility for items members may genuinely need — like appliance upgrades or seasonal purchases — Costco strikes that balance of supporting business growth while demonstrating understanding of the economic pressures many households currently face.

For members planning bigger purchases in the coming months, this new payment option might be exactly what they need to make those investments more manageable in today’s challenging economic landscape.
