Walk into any Costco warehouse, and you’ll see it. The "white wall." It’s that massive refrigerated section where the five-dozen packs of eggs sit stacked like construction materials. If you’re standing there wondering how much is 5 dozen eggs at Costco, you’re likely trying to balance your grocery budget against the reality of inflation. Honestly, the price isn't a static number. It fluctuates based on where you live, bird flu outbreaks, and whether you're looking at conventional or organic options.
Generally, you're looking at a price point between $12.00 and $18.00 for those 60-count flats of large white eggs.
Prices change. Fast. Just last year, during the height of the avian flu supply crunch, these same flats spiked to over $15 in many regions, leaving shoppers stunned. Now, things have leveled out a bit, but you won't find the $8 steals of 2019 anymore.
The Math Behind the 60-Count Flat
People buy in bulk to save. It’s the Costco way. But does the math actually hold up when you’re staring down five dozen eggs? If you buy a 60-count pack for $15.00, you are paying exactly **$0.25 per egg** or $3.00 per dozen. Compare that to a local supermarket where a single dozen might run you $4.50 or $5.00 for the exact same grade of large white eggs. The savings are real, but they require a commitment to eating five dozen eggs before they go south.
Most Costco locations sell the five-dozen pack as two separate 30-count flats shrink-wrapped together. This is actually a lifesaver for organization. You can stack them. You can split them with a neighbor. You can fit them on a standard fridge shelf without rearranging your entire life.
It's weirdly satisfying to see that much protein for under twenty bucks. Some weeks, the price drops to $11.89 in the Midwest or Texas, while shoppers in Hawaii or Alaska might see closer to $19.00. Shipping logistics matter. Regional grain costs matter. Even the cost of the cardboard packaging influences that final tally on your receipt.
Organic vs. Conventional: The Price Gap
Costco's Kirkland Signature brand is famous for quality. If you move away from the standard 60-count white eggs and look at the organic, pasture-raised, or cage-free options, the "5 dozen" math changes. Usually, the organic eggs aren't sold in a 60-count flat. Instead, they come in 2-dozen or 3-dozen packs.

If you tried to "bulk up" to 60 organic eggs by buying multiple smaller packs, you’d likely spend closer to $30.00 to $35.00. That’s a massive jump. Is it worth it? For some, the darker yolks and the lack of antibiotics are non-negotiables. For others, an egg is an egg, and the $14 conventional flat is the clear winner for the family breakfast scramble.
Why Do Prices Fluctuate So Much?
You might go to Costco on a Tuesday and pay $13.50, then go back two weeks later and see $15.25. It’s annoying. I get it. The primary driver here is the Commodity Egg Market. Eggs are traded like oil or gold. When a major producer in Iowa or Indiana has to cull a flock due to disease, the supply drops instantly. Demand doesn't change—people still want their omelets—so the price at the warehouse rises to reflect that scarcity.
Costco actually works on very slim margins. They aren't trying to gouge you on eggs. They use staples like milk, rotisserie chickens, and eggs as "loss leaders" or low-margin items to get you through the door. If the market price for eggs goes up, Costco often absorbs some of that cost before passing it on to you, but they can't hold the line forever.
Recent data from the USDA and Bureau of Labor Statistics shows that while general inflation has cooled, "food at home" costs remain sticky. Eggs are the poster child for this volatility.
Storage Realities: Can You Actually Use 60 Eggs?
Buying 60 eggs is a bold move for a two-person household. Let's talk shelf life. According to the USDA, eggs are generally good for 3 to 5 weeks in the refrigerator from the day you bring them home.
- The Float Test: If you're worried about an older egg, drop it in a bowl of water. If it sinks, it's fresh. If it stands on one end, it's getting old but still okay to cook. If it floats? Toss it.
- Baking: Large batches of cookies or cakes use up those 60 eggs faster than you’d think.
- Hard-Boiling: This is the secret weapon for Costco members. A dozen hard-boiled eggs in the fridge is the ultimate high-protein snack for the week.
If you aren't hitting the gym or feeding a small army, five dozen eggs is a lot of pressure. I’ve seen people buy the 60-count and end up throwing away the last dozen because they got "egg fatigue." At that point, the savings disappear. You’ve basically paid for the convenience of throwing food away.

Regional Variations: Not All Costcos Are Equal
Location is everything. If you’re shopping at the Costco in Brooklyn, New York, you’re going to pay a premium compared to someone at the warehouse in Springfield, Missouri.
In California, state laws regarding cage-free housing for hens (like Proposition 12) have historically pushed prices higher than in states with looser regulations. You might find that the "cheap" 60-count flat in a California Costco is actually a cage-free product because that's the legal baseline, which naturally raises the price floor.
I checked recent member reports from across the country. In early 2026, here is the rough landscape:
- Midwest (Ohio/Illinois): $12.99 - $14.50
- West Coast (California/Washington): $15.75 - $17.99
- Southeast (Florida/Georgia): $13.25 - $15.00
- Northeast (NJ/NY/MA): $14.80 - $16.50
These aren't guaranteed, but they give you a ballpark.
The "Member-Only" Value
Remember, you’re paying $65 or $120 a year for the privilege of buying these eggs. If you only go to Costco for eggs, the math is bad. You’d need to buy dozens upon dozens of flats to break even on the membership fee alone. But, if you’re already there for the $5 chicken and the cheap gas, adding the 5-dozen egg pack to your cart is one of the smartest moves you can make for your grocery budget.
The quality of Kirkland eggs is consistently high. They are Grade A or AA, meaning the whites are thick and the yolks are firm. Compare that to some "budget" eggs at discount grocers where the whites are watery and the shells are thin enough to shatter if you look at them wrong.

How to Maximize Your Egg Purchase
If you decide to pull the trigger on the 60-count, don't just shove them in the fridge and hope for the best.
Take them out of the plastic wrap. The shrink-wrap can trap moisture, which isn't great for the shells. Keep them in the original cardboard flats, though. The cardboard protects them from absorbing odors from other foods in your fridge (nobody wants a "leftover onion" flavored scrambled egg).
Put them on a shelf, not in the door. The temperature in the fridge door fluctuates every time you open it. For a bulk purchase like 60 eggs, you want them in the coldest, most stable part of the refrigerator—usually the back of the middle or bottom shelf.
Actionable Steps for Your Next Trip:
- Check the Julian Date: Look for the three-digit code on the side of the pack. It represents the day of the year the eggs were packed (001 is January 1st, 365 is December 31st). Choose the highest number for the freshest eggs.
- Inspect the Bottom: Carefully lift the 30-count flats to check for leaks. One cracked egg at the bottom of a 60-pack creates a sticky mess that glues the eggs to the carton.
- Compare the Per-Egg Cost: Use your phone's calculator. Sometimes the 2-pack of 18-count eggs (36 total) is on sale for a better price per unit than the 60-count flat. Don't assume the biggest box is always the cheapest.
- Plan Your Protein: If you buy 5 dozen, commit to a "big batch" activity like meal-prepping breakfast burritos or making a few quiches to freeze.
Costco's 5-dozen egg pack remains one of the best barometers for the US economy and a staple for anyone trying to eat healthy on a budget. It's simple, it's bulky, and as long as you have the fridge space, it's usually the right call.
Key Insights Summary:
- Expect to pay between $12 and $18 depending on your zip code.
- The price per egg is almost always lower than standard grocery stores, often by 30% or more.
- Always check the "Pack Date" (Julian Date) to ensure you can actually finish all 60 before they expire.
- Conventional white eggs are the volume leaders, but check the 24-count organic packs if quality is your priority over raw quantity.
