Aldi vs Migros Prices in Switzerland: The 2026 Head-to-Head

On a comparable everyday basket, Aldi Suisse comes out cheaper than Migros in every K-Tipp basket test, by about 11 percent in the 53-item basket of June 2022 and by a little over 5 percent in the 100-item basket of 28 August 2025. That gap closes to near-parity when Migros M-Budget is the comparison line, and reverses when Migros runs a strong Aktion week. The honest answer: there is no single winner. Aldi's strength is permanent low prices on shelf-stable basics. Migros's strengths are assortment, fresh selection, weekly promotions and the M-Budget line. Real Swiss households shop at both. This guide gives the actual price gaps by category, the K-Tipp and RTS data, and the household-by-household split that gets the lowest annual grocery bill.

Sources checked regularly. Data from K-Tipp comparative basket tests, RTS A Bon Entendeur basket test of April 2024, Saldo, bonus.ch, and direct verification at migros.ch and aldi-suisse.ch. Current offers in the Rappn app, updated daily.

The price gap, in real numbers

The takeaway is structural. M-Budget is Migros's permanent answer to the discounters; on the 200+ products M-Budget covers, the price gap to Aldi is small. Outside M-Budget, the gap widens to discounter-typical levels. The full discounter-vs-discounter view is in Lidl vs Aldi Switzerland.

August 2026 update: ALDI put exactly this comparison on the front pages, claiming up to 32% savings over Migros with two printed receipts, and Migros filed a formal complaint. We re-ran every printed line against our price database and real user receipts: across 15 like-for-like products the gap was 12 centimes. The full analysis is in our Aldi receipt-ad fact-check.

Category by category, where each is strong

Aldi is consistently strong on:

Branded packaged goods that Aldi stocks (Nutella, Kellogg's, Coca-Cola, Barilla), although bonus.ch found branded prices mostly identical across the big chains in August 2025. Own-brand organic products under "retour aux sources" (organic milk CHF 1.80/L vs Migros Bio CHF 1.85). Wine, beer and spirits, Aldi sells alcohol; Migros does not. Meat in the discount tier. Household basics: detergent, dishwasher tablets, toilet paper. Convenience and frozen ranges.

Migros is consistently strong on:

M-Budget on covered staples. On the 200+ products M-Budget covers (milk, pasta, rice, oil, bread, cheese, eggs), prices are at discounter level. Fresh selection breadth, a mid-sized Migros carries 20,000-30,000 SKUs versus 1,500-2,000 at Aldi. Aktion-week items: 30-50% off a specific item can undercut Aldi's everyday price. The 5 February 2026 calendar shift to Thursday-Wednesday Aktion windows aligned this with Aldi Suisse, sharpening the competition. Migros Bio on premium organic, prepared foods (sushi, fresh-baked bakery, cheese counter), and the Cumulus loyalty card (1% back plus personalised vouchers, Aldi has no loyalty programme; full breakdown in Swiss loyalty card wallet).

Practical differences beyond price

Store coverage. Aldi Suisse operates around 244 stores across Switzerland (February 2026); Migros runs 659 M, MM and MMM supermarkets (end of 2025), or 707 sales points once teo, Alnatura and outlet formats are counted in, on top of the separate Migrolino network. Outside major cities, a Migros is far more likely to be the nearest option. Aldi's network is densest in the Mittelland, Romandie and major German-speaking cantons; sparse in Ticino and the Alpine cantons.

Store experience. A Migros M is a destination-format hypermarket with full bakery, butcher, fishmonger, prepared-food bar. An Aldi Suisse store is a 1,000-1,500 m² no-frills format: pallets, cardboard cuts, fewer staff, faster checkout.

Opening hours. Migros Bahnhofplatz Zürich (Mon-Fri 06:30-22:00, Sat 07:00-22:00, Sun open). Aldi central Zürich (Mon-Sat 07:00-21:00, Sun closed). For Sunday shopping, only Migros station branches and the airport are realistic. The full Sunday/holiday picture is in Easter grocery shopping Switzerland.

Online shopping. Migros Online and migros.ch deliver groceries nationwide. Aldi Suisse closed its own delivery service, ALDI now, in 2026 (20 Minuten and Blick, both 23 August 2026), and it never offered click and collect. For households that depend on delivery, only Migros of the two delivers groceries.

Loyalty. Cumulus at Migros (1% + personalised vouchers). Aldi has no loyalty programme. The Cumulus value is roughly CHF 120-300/year on a CHF 1,000/month Migros basket.

Alcohol. Migros does not sell alcohol in its supermarkets. Aldi sells wine, beer, and spirits. Denner inside the Migros Group sells alcohol and is the typical workaround.

Range depth. A mid-sized Migros: 20,000-30,000 SKUs. A typical Aldi Suisse: 1,500-2,000 SKUs. For specific brands, regional products, ethnic ingredients, baby food specialties, the Migros range is several times deeper.

The smart household split

The wrong question is "Aldi or Migros?" The right question is "what should I buy where?"

Buy at Aldi: Branded packaged goods Aldi stocks (Nutella, cereals, Coca-Cola), wine/beer/spirits, everyday meat (especially poultry and frozen lamb), organic milk, eggs and basic vegetables under retour aux sources, household basics (detergent, paper goods), fresh fruit and vegetables when carried, coffee beans, oil, basic pasta and rice (on weeks Migros has no Aktion).

Buy at Migros: M-Budget staples in 2L milk, large pasta packs, eggs (price parity with Aldi, often-broader selection); Aktion-week items at 25-50% off; specific brands and regional products Aldi doesn't stock; fresh meat from the counter; Migros-Bio specialty organic items; prepared meals, sushi, fresh-baked bakery; anything you would otherwise need to drive elsewhere for.

How much this split saves depends on your basket and on the week's Aktionen, so we put no franc figure on it. The full breakdown of how to combine cross-store shopping with the new Thursday-Wednesday Aktion calendar is in how Swiss Aktionen work.
