Cheapest Supermarket in Switzerland: The Definitive Ranking
We analysed every major independent test, real prices and data from 5 chains to give you an honest answer. With comparison table and final scores.
It's the question everyone living in Switzerland asks sooner or later: where should you do your grocery shopping?
The short answer is that there is no single cheapest supermarket. It depends on what you buy, which week you buy it and whether you use promotions. But when you put together the results from K-Tipp, RTS "A Bon Entendeur", bonus.ch and Beobachter, a fairly clear picture emerges.
Here we compare the five major Swiss supermarkets – Migros, Coop, Aldi, Lidl and Denner – on everything that matters: basket price, range, store count, loyalty cards, promotions, alcohol, online shopping and more.
Not a sponsored comparison. Rappn has no commercial agreements with any retailer.
The price ranking: numbers from independent tests
K-Tipp, 100 everyday products (August 2025):
| Rank | Supermarket | Total cost | Difference from Aldi |
|---|---|---|---|
| 1 1st | Aldi | CHF 230.94 | — |
| 2 2nd | Lidl | CHF 232.83 | +0.8% |
| 3 3rd | Migros | CHF 243.54 | +5.5% |
| 4th | Coop | CHF 250.70 | +8.6% |
K-Tipp confirmed that M-Budget and Prix Garantie are now priced at discount level on many everyday items. The catch is availability: in smaller stores, those cheapest products are not always on the shelf.
RTS "A Bon Entendeur", 30 basic products (2024):
| Rank | Supermarket | Total cost | Difference from Lidl |
|---|---|---|---|
| 1 1st | Lidl | CHF 162.05 | — |
| 2 2nd | Aldi | CHF 166.59 | +2.8% |
| 3 3rd | Coop | CHF 167.82 | +3.6% |
| 4th | Migros | CHF 170.37 | +5.1% |
| 5th | Denner | CHF 181.67 | +12.1% |
The surprise was Denner: the discounter came last. The reason is structural. It has no real budget line and for some products the cheapest available option is still the standard branded item.
The overall conclusion is consistent: Lidl and Aldi are usually cheapest. Migros gets surprisingly close thanks to M-Budget. Coop is often the most expensive on basics, but makes up for it with strong weekly promotions. Denner has lost its cheapest-discounter status since 2024.
From bonus.ch in August 2025: branded products like Nutella, Barilla and Coca-Cola are priced almost identically across Swiss supermarkets. The meaningful differences are on budget lines, own brands and promotions.
The 5 supermarkets, one by one
Lidl wins most independent comparisons. It combines aggressive base prices with a strong in-store bakery and the Lidl Plus app, which is the only true loyalty programme among Swiss discounters.
Aldi is almost identical on price. Its strength is simplicity: no card, no coupons, no app required. Since 2025 Aldi has started closing some city-centre stores, but it remains one of the best-value chains in the country.
Migros invested CHF 500 million in price cuts in 2025. M-Budget is now at or near discount level for many staples. Add a huge range and the Cumulus programme, and Migros becomes the best all-round option for many families.
Coop has the biggest network, the strongest organic range and the best online platform in Switzerland. It is often pricier on basics, but its promotions are among the most aggressive in the market.
Denner has the densest discount network and is excellent for promotions on coffee, wine and chocolate. But because it lacks a true budget line, it performs worse in standardised basket tests than many shoppers expect.

The expert tip
The biggest savings do not come from choosing one supermarket. They come from combining them: staples on budget lines, pantry items only on promotion, meat at Prix Garantie or during promo weeks, coffee and wine at Denner.
For a Swiss family, that strategy can realistically save CHF 200 to 400 per month.

Frequently Asked Questions
What is the cheapest supermarket in Switzerland?
In independent tests, Lidl and Aldi come out cheapest most often. Migros gets close thanks to M-Budget. Coop is pricier on basics but stronger on promotions, while Denner is best for targeted deals on coffee, wine and chocolate.
How much can you save?
The gap between Coop and Lidl or Aldi is often around 8 to 10% on a standard basket. With a smart mix of discounters and promotions, a family can save CHF 200 to 400 per month.
Is M-Budget as cheap as Aldi?
Mostly yes. K-Tipp confirmed in August 2025 that M-Budget and Prix Garantie are priced at discount level on many staples. The main issue is that they are not always available in smaller stores.
Why is Denner more expensive than Migros?
Because Denner has no true budget line. Standardised tests pick the cheapest available item, and at Denner that is often still the standard product rather than a lower-cost private-label option.
