Starting today, Costco is implementing a new schedule that includes exclusive hours for Executive members.
The timetable was first disclosed in an email sent to members earlier this month, in which the big-box warehouse club detailed plans to change its operating hours in order to add some appealing new amenities for its highest-paying members. The initiative follows a solid financial quarter for Costco. According to its third quarter 2025 financial report, the company’s sales increased 8% year on year, from $57.39 billion last year to $61.96 billion this year.
Here’s all you need to know about the modified schedule.

How are the hours and membership benefits changing?
Previously, most Costco locations were open from 10 a.m. to 8 p.m. on weekdays, 9:30 a.m. to 6 p.m. on Saturday, and 10 a.m. to 6 p.m. on Sunday.
Today, the company introduced an earlier start time for each day, which is only available to its Executive tier. Throughout the week, Costco will now open at 9 a.m. for Executive members, providing them an extra hour of shopping Sunday through Friday and 30 minutes on Saturday. In addition, Costco will provide Executive members with a monthly $10 credit for orders totaling $150 placed through the company’s “Same-Day” service or Instacart.
Aside from these Executive tier options, Costco plans to extend its Saturday hours to a 7 p.m. closing time for all members beginning July 5.

Why is Costco implementing these changes?
To buy at Costco, users must first purchase one of two membership plans: the ordinary Gold Star Membership ($65 per year) or the Executive Membership ($130 per year).

Previously, Costco’s most loyal customers were drawn to the pricier Executive Membership, which offers an annual 2% incentive on qualified purchases and can earn up to $1,250 in cash back each year. Now, the corporation is attempting to sweeten the bargain by offering a special shopping experience—a tactic already in place at Sam’s Club, the retailer’s major competitor.

Costco’s adoption of the notion makes logical, given how important Executive members have become to the company’s overall financial health. On a May 29 earnings call, Gary Millerchip, Costco’s senior vice president and CFO, announced that the firm currently had 37.6 million senior members, a 9% increase from the same quarter in 2024. He also stated that at the end of the third quarter 2025, executive members represented for 47.3% of paying members but 73.1% of global revenues. Early access to the club’s inventory (and famed food court) is one way Costco keeps its most loyal customers coming back for more.
