You’re halfway through the week, you just realized you're out of the giant pack of Kirkland paper towels, and you’re wondering if you can make it before the doors lock. We've all been there. Trying to figure out costco what time do they close isn't as straightforward as a quick Google search might make it seem, because "closing time" depends heavily on which day it is and what exactly you’re trying to do.
Honestly, it's a bit of a dance. If you’re just hitting the main warehouse for a rotisserie chicken, that’s one thing. If you need a tire rotation or a prescription filled, you’re looking at an entirely different set of rules.
The Standard Weekday Rush
Most Costco warehouses across the country follow a pretty rigid schedule from Monday to Friday. Usually, the doors swing shut at 8:30 PM.
This gives most people a decent window after work to get their shopping done, but don’t expect to roll in at 8:25 PM and have a leisurely stroll. The staff starts "sweeping" the aisles toward the front around 15 minutes before closing. If you’re a Gold Star or Business member, your shopping window technically starts at 10:00 AM, but many locations actually let people in a few minutes early if the registers are ready.
Executive Members Get an Edge
One thing many people miss is the early access for Executive Members. While the official "close" is the same for everyone, Executive Members often get in at 9:00 AM on weekdays. That extra hour in the morning is a game-changer if you want to avoid the 6:00 PM chaos when everyone else is frantically grabbing dinner.
The Weekend Shift: Saturday and Sunday
Weekends are where the schedule really tightens up. It's a common mistake to think Costco stays open late on Saturdays. It doesn't.
On Saturdays, most locations close their doors at 7:00 PM.
Sundays are even shorter. You’re looking at a 6:00 PM closing time. If you’re planning a Sunday afternoon trip, you’ve basically got to be out of there by late afternoon, or you’ll find yourself staring at those massive metal gates coming down.
What About the Gas Station and Pharmacy?
This is where the confusion usually starts. The services inside and outside the warehouse don't play by the same rules as the main floor.
- Costco Gas Stations: These are the early birds. Most open as early as 6:00 AM. They also stay open later than the warehouse. On weekdays, you can usually pump gas until 10:00 PM. On Saturdays, they often close around 8:30 PM, and Sundays around 7:30 PM.
- Costco Pharmacy: The pharmacy usually has much shorter hours. They often close by 7:00 PM on weekdays and 6:00 PM on Saturdays. The biggest kicker? The pharmacy is almost always closed on Sundays. Don't show up with a prescription on a Sunday expecting to get it filled; you'll be disappointed.
- Tire Center: Usually follows the warehouse hours (8:30 PM weekdays), but they stop taking new walk-ins much earlier. If you aren't there by 6:00 PM or 7:00 PM, they likely won't have time to touch your car.
Business Centers Are a Different Beast
If you happen to shop at a Costco Business Center—which are different from the regular warehouses—the schedule is flipped. These locations are designed for restaurant owners and small businesses.
They open incredibly early, sometimes at 7:00 AM, but they also close early. Most Business Centers wrap up by 6:00 PM on weekdays and might even be closed or have very limited hours on Sundays. If you’re looking for a "regular" Costco experience with a food court and clothing, the Business Center isn't your spot anyway.
Holiday Closures to Watch for in 2026
Costco is famous for being one of the few major retailers that actually shuts down for holidays to give their employees a break. In 2026, you can count on them being closed entirely on:
- New Year’s Day
- Easter Sunday
- Memorial Day
- Independence Day (July 4th)
- Labor Day
- Thanksgiving Day
- Christmas Day
They do usually stay open on Martin Luther King Jr. Day and Presidents' Day, but it's always worth a quick check on the app if you're driving from far away.
Pro Tips for Beating the Clock
If you're heading there near closing time, keep these bits of insider info in mind. The "best" time to shop to avoid the crowds is actually Tuesday or Wednesday evening around 7:30 PM. The post-work rush has died down, and you still have an hour before the 8:30 PM cutoff.
Also, remember that the food court often stops taking orders for whole pizzas about 30 minutes before the warehouse closes. If you want a $9.99 pepperoni pizza for dinner, don't wait until 8:29 PM to try and order it.
Actionable Next Steps
- Check the App: Use the "Warehouse Locator" in the Costco app to confirm if your specific location has "Executive Hours" starting at 9:00 AM.
- Gas First: If you need gas and groceries, hit the warehouse first. The gas station stays open later, so you don't need to rush the pumps before they close the main doors.
- Pharmacy Prep: Call ahead for prescriptions, especially if it’s a Saturday, as they will not be there to help you on Sunday morning.
- Watch the Clock on Saturdays: Set a reminder for 6:00 PM on Saturdays. It’s easy to lose track of time and arrive just as they are locking up at 7:00 PM.
