Eggs, a product that seems simple but actually hides a lot of underlying movements, are starring this May in a price dance that leaves no one indifferent. Among the shelves of Mercadona and Carrefour, the perception of daily shopping changes depending on the format and the chain.

Meanwhile, the organization FACUA offers detailed monitoring that reveals a certain balance but also small occasional drops in chains like Carrefour. This makes buying eggs not only a matter of taste but also of economic strategy.

📍 Analyzed supermarkets: Mercadona, Carrefour, Alcampo, Consum, Dia, Eroski, and Hipercor
🔥 Most common formats: 24 units (M/L), 12 units (L), and 12 units (M)
⏱️ Study date: May 11, 2026

Current price comparison

The panorama shows that Alcampo takes the medal for the lowest price in the 24-egg format, with a cost of 4.39 euros, well below Mercadona or Carrefour’s 5.60 euros. These last two chains are almost tied, keeping prices around 5.60 euros.

In the case of 12-unit size L eggs, the gap is even more evident: Alcampo offers the best option at 2.27 euros, followed by Carrefour at 3.19 euros and Mercadona at 3.20 euros. This difference may seem small but adds up a lot in regular shopping.

Variations in size M eggs

As for 12-unit size M eggs, Carrefour sets the most competitive price at 2.60 euros. The rest of the chains remain fairly clustered between 2.90 and 3.10 euros, a fairly tight range that makes choosing only based on price difficult.

Factors impacting egg prices

Logistical and production context

The volatility observed in egg prices during the past year is related to multiple factors, among which energy costs, logistical problems, and avian flu stand out. These variables caused prices to reach unexpected levels, especially during 2025, when the dozen almost touched 4 euros.

After this rise, the market now shows some stabilization, although prices remain higher than before the crisis. This balance is good news for consumers, but the evolution must be closely monitored.

Impact of VAT and regulations

Eggs are taxed with a super-reduced rate of 4%, considered a basic food. This VAT was temporarily reduced to 0% during the crisis between 2022 and 2024 but returned to 4% in 2025. This change has played a key role in price evolution, especially when production cost pressure was greater.

The current consumer perceives the effect of these policies and adjustments, which directly influence the final price at Mercadona, Carrefour, and other chains.
