How the price of eggs has changed in supermarkets including Mercadona in 2026

Eggs, an infallible classic in the shopping basket, have been the subject of constant price changes over the past year. Mercadona, Carrefour, and other major chains show fluctuations that make any shopper wonder where the best deal is today.

These variations are not a whim but the result of factors ranging from logistics to production costs, including issues such as avian flu and energy. But if you've wondered what the exact situation is right now, you have a clear map below.

Price of eggs in major supermarkets in 2026

Comparison by formats and chains

Eggs in packs of 24 units, a less common but emblematic format for many families, sell at almost the same price at Mercadona and Carrefour: €5.60 and €5.59, respectively. But if we go down to twelve-unit formats, the story changes radically.

In the L (large) category, Alcampo offers the lowest price, €2.27, while Carrefour stands out with the highest price, €4.28. Mercadona remains at an intermediate level with €3.20.

Medium-sized eggs (M) reveal another panorama

Carrefour leads as the cheapest option at €2.60, while other chains move within a narrow range: from €2.98 at Alcampo up to €3.10 at Eroski. Mercadona sits right in the middle, at €3, reflecting stability in this segment.

Factors explaining the evolution of egg prices

Context of the past decade and avian pandemic

Egg prices have risen steadily since 2023, driven by increased energy costs and health problems such as avian flu that impacted production. 2025 marked the peak with prices nearing €4 per dozen in many supermarkets, especially for free-range and large formats.

2026, on the other hand, started with slight stabilization and some decreases, although without returning to pre-spike levels.

VAT and its role in the final price

Eggs are taxed at the reduced 4% VAT rate because they are a basic food item. During the price crisis, this tax was temporarily reduced to 0%, but since 2025 it remains at 4%. In 2026, there have been occasional proposals to reduce it again, but with no general application.

Price details by supermarkets and formats

Mercadona and its most complete offer

Mercadona offers a wide range, from super large XL eggs (€4.30 per 12 units) to free-range ones (€3.50 per dozen). There is also a notable variety of small formats such as 6-unit packs at €2.10.

Prices and options at Carrefour, Alcampo, Eroski, and Hipercor

Carrefour adjusts in the medium segment with €2.60 and has the highest price for large L eggs. Alcampo is the best option for large eggs at €2.27, while Eroski and Hipercor move at slightly higher prices, especially for free-range eggs.

The FACUA website provides daily updates confirming this price trend, which, as you can see, is not uniform and depends greatly on the chain and chosen format. This makes it interesting to compare before buying and to pay attention to details such as size class and egg type.

By the way, if you’re interested in seeing how milk prices have changed or how Mercadona has adjusted the prices of many basic products, you will find updated and useful information.

The reality is that although eggs remain an affordable food, their price fluctuations require attention from vigilant consumers, especially when it comes to choosing format and supermarket chain.
