If there's one grocery item that's had a wild ride lately, it's eggs. After months of sky-high prices driven by bird flu outbreaks, egg prices have finally started coming down again in 2026 — and the battle between Costco and Walmart over who sells them cheapest has gotten genuinely interesting.
So let's just look at the numbers.
If you haven't read the full series yet, start with our Costco vs. Walmart 2026 overview — it covers the big picture before we get into the details.
The Current Numbers (April 2026)
Here's what eggs actually cost right now, broken down by what actually matters — price per egg, not the sticker price on the package.
| Store | Package Size | Price | Price Per Egg |
|---|---|---|---|
| Walmart (Great Value) | 12 count (1 dozen) | ~$4.47 | 37.3¢ |
| Costco (Kirkland Organic) | 24 count (2 dozen) | $8.59 | 35.8¢ |
| Costco (bulk pack) | 60 count (5 dozen) | $14.92 | 24.9¢ |
*Costco 24-count price from Chicagoland area, April 7, 2026. Walmart reflects current Great Value conventional large egg pricing. Prices vary by region.
That 60-count Costco pack is genuinely hard to beat on a per-egg basis. You're saving about 12 cents per egg compared to a Walmart dozen — which sounds small, but if your household goes through 2 dozen a week, that adds up to roughly $75 in savings per year.
Why Walmart Still Wins for a Lot of People
Here's the thing about eggs: they expire. And unlike toilet paper or laundry detergent, you can't just stack 60 eggs in a closet and forget about them for three months.
For a single person or a couple, buying 60 eggs at once is a real gamble. If you end up throwing away even 20 of them because they went bad before you could use them, here's what happens to your math:
| Scenario | Eggs Wasted | Effective Price Per Egg |
|---|---|---|
| Use all 60 | 0 | 24.9¢ ✅ |
| Waste 10 | 10 | 29.9¢ |
| Waste 20 | 20 | 37.4¢ — same as Walmart |
| Waste 25+ | 25+ | More expensive than Walmart ❌ |
Waste 20 eggs and you've completely erased the Costco advantage. Waste more than that and you're paying more than if you'd just grabbed a Walmart dozen every week. That's the "Waste Tax" in action — and it's the number one reason people think they're saving at Costco when they're actually not.
A Note on Egg Quality
This comparison isn't perfectly apples-to-apples. Walmart's cheapest eggs are typically Grade A conventional. Costco's Kirkland Signature eggs are usually Grade AA — a small but genuine step up, with firmer whites and more defined yolks.
If you're buying organic, Costco pulls even further ahead. Their organic free-range eggs frequently run 30–40% cheaper per dozen than premium brands like Vital Farms at Walmart. So if you care about egg quality, the Costco advantage is even stronger than the raw numbers suggest.
So Which Store Should You Buy Eggs From?
Here's the honest decision guide:
Buy at Costco if:
- You have a household of 3 or more people
- You cook or bake with eggs regularly
- You realistically go through 2+ dozen eggs per week
- You prefer Grade AA or organic quality
Buy at Walmart if:
- You live alone or with one other person
- You don't cook eggs frequently enough to justify bulk
- You want the lowest upfront cost with zero waste risk
Final Thought
The Costco bulk pack math is genuinely compelling for the right household. But "cheaper per egg" only matters if you eat every egg you buy. If your fridge regularly sees a few eggs go bad before the carton runs out, stick with Walmart's smaller packs — your wallet will actually come out ahead.
