Guide
Updated September 2026: a 50-wash bottle and a 20-wash box only become comparable once you divide the pack price by the wash count. This guide shows how to do that, where powder, liquid and capsules each do well, and when an own brand or a branded detergent on promotion is worth it.
Laundry detergent is one of those quiet household costs that adds up over a year, and the headline price on the shelf almost never tells you what a wash actually costs. A big bottle can look dear next to a small box and still be cheaper to use, because what matters is the price per wash, not the price per pack. In Switzerland you can buy detergent at every chain and discounter, in powder, liquid and capsule formats, as branded products like Persil, Ariel and Total or as own brands like M-Budget, Prix Garantie, Oecoplan, Aldi's Tandil and Lidl's Formil. This guide explains how to find the cheapest option that still washes well, and how to compare like with like.
Sources checked regularly: Swiss consumer-test publications K-Tipp, Kassensturz (SRF) and saldo for blind detergent tests across powder, liquid and capsule formats and for own-brand results; the retailers' own published assortments and pack sizes (Migros, Coop, Aldi, Lidl, Denner, Otto's); and international consumer bodies (UFC-Que Choisir, Altroconsumo) for format comparisons. Specific prices, pack sizes and promotions change constantly, so this guide explains how to judge value rather than quoting figures that go stale; check live prices and the price per wash in the Rappn app.
Rappn is an independent grocery price comparison app in Switzerland, with no commercial agreements with any retailer or brand. We are not paid by Coop, Migros, Aldi, Lidl, Denner, Aligro or Otto's, nor by Persil, Ariel or any detergent maker, to rank them, and nothing below is sponsored.
The only number that matters: price per wash
The single most useful habit when buying detergent is to ignore the pack price and work out the price per wash. Every pack states how many wash cycles it is dosed for, so you simply divide the price by that number of washes. A 50-wash bottle at one price and a 20-wash box at another are impossible to compare any other way, and the bigger or more expensive-looking pack is often the cheaper one per load. Capsules make this trickier because the convenience is baked into the price, and powder is usually the lowest cost per wash because you control the dose. Get into the habit of reading the wash count, and you will see through a lot of shelf-edge illusions.
Laundry detergent only compares fairly per wash, since pack size, dose and format all change the real cost. Rappn lines up the detergent offers across chains with the unit price, so you can work out the cost per wash before you choose a pack.

Offers
Powder, liquid or capsules: which format to buy
| Format | Price per wash | Best for | Watch out for |
|---|---|---|---|
| Powder (heavy-duty / Vollwaschmittel) | Usually lowest | Whites, tough stains, value buyers; you set the dose | Can leave residue on dark fabrics; less convenient |
| Liquid | Middle | Colours, frequent washing, gentle care; no whitener | Easy to over-dose, which wastes money |
| Capsules / pods | Usually highest | Convenience, no measuring, no spills | Fixed dose; you pay a premium per wash |
| Discounter own brand (any format) | Often very low | Stretching the budget without dropping much quality | Fewer fragrance and specialist options |
Own brand vs branded: compare the cost per wash
The biggest lever on a detergent bill is usually switching from a name brand to an own brand. Branded heavyweights like Persil, Ariel and Total are reliable and heavily advertised, but the own-brand lines from the Swiss chains, M-Budget at Migros, Prix Garantie and Oecoplan at Coop, plus discounter brands such as Aldi's Tandil and Lidl's Formil, cost noticeably less per wash. Swiss and European consumer testers, including K-Tipp, Kassensturz, saldo, the FRC, UFC-Que Choisir and Altroconsumo, repeatedly find that several discounter and own-brand detergents wash as well as or better than far pricier branded products in blind tests, with powder formats generally leading on stain removal. The practical takeaway is that trading down is frequently a free saving, especially on everyday loads.

Promotions, pack size and the eco question
Detergent is a classic promotion item, so the cheapest detergent this week is often whichever brand is on a deep Aktion, not the one that is normally cheapest. Large packs usually cut the price per wash further, but only buy a giant box if you have the space and will actually use it before it cakes or the fragrance fades. On the eco side, concentrated detergents, refill pouches and ecolabel powders can lower both cost and packaging, though some testers note that the gentlest ecological formulas can be a touch weaker on stubborn stains, so match them to lightly soiled loads. If you compare total household value rather than a single product, our best value supermarket guide weighs price against quality across the shop.
How to find today's detergent deals
Because formats, pack sizes and promotions all move at once, no static article can tell you the cheapest detergent for your machine this week. Live prices can. This is exactly what Rappn does: you search a product, for example a heavy-duty powder or a pack of capsules, and see every active offer across Coop, Migros, Aldi, Lidl, Denner, Otto's and Aligro at once, with the discount and the store. The unit price, per kilo, per litre or per wash, sits next to the shelf price, which is the only honest way to compare a big bottle against a small box. Everything is filtered to your canton, and you can set an alert so you are told when the detergent you buy regularly goes on offer. It is free, and it has no commercial deal with any retailer or brand. If you tend to stock up, our guide to bulk buying in Switzerland pairs naturally with detergent.
So what is the cheapest laundry detergent in Switzerland?
The neutral answer: for most households it is an own-brand or discounter powder bought in a larger pack and dosed correctly, with the lowest price per wash, topped up by whatever branded detergent happens to be on a strong promotion that week. Capsules cost more per wash and are worth it only if you value the convenience. There is no detergent that is "always cheapest", and which one is on promotion changes every week, so compare the current offers and the price per wash side by side. That is the whole reason Rappn exists.

Frequently Asked Questions
What is the cheapest laundry detergent in Switzerland?
For most households the lowest cost per wash comes from an own-brand or discounter powder, such as M-Budget or Prix Garantie at the big chains, or Tandil at Aldi and Formil at Lidl, bought in a larger pack and dosed correctly. Branded detergents like Persil, Ariel and Total become competitive mainly when they are on a deep promotion. No single detergent is always cheapest, because pack sizes and Aktionen change every week, so the reliable method is to compare the price per wash across chains rather than the price on the shelf.
How do I compare laundry detergent prices fairly?
Compare the price per wash, not the price per pack. Every pack states the number of wash cycles it is dosed for, so divide the pack price by that number. A large bottle can look expensive next to a small box and still be cheaper per load. Capsules usually cost the most per wash because the convenience is built in, and powder is often the cheapest because you control the dose. In the Rappn app the unit price, including per wash where available, is shown next to the shelf price so you can compare like with like.
Is powder, liquid or capsule detergent the best value?
Powder is usually the lowest cost per wash and Swiss and European consumer tests find it strongest on whites and tough stains, though it can leave residue on dark fabrics. Liquid sits in the middle on price and is gentler on colours and good for frequent washing, but has no whitening agent. Capsules are the most convenient and typically the most expensive per wash, with a fixed dose you cannot adjust. Match the format to the load: powder for value and whites, liquid for colours, capsules only if you are paying for convenience.
Are own-brand detergents as good as Persil or Ariel?
Often yes for everyday washing. Swiss and European consumer testers, including K-Tipp, Kassensturz, saldo, the FRC and UFC-Que Choisir, repeatedly find that several discounter and own-brand detergents wash as well as or better than far pricier branded products in blind tests, with powder formats generally leading on stain removal. Branded detergents remain reliable and offer more fragrance and specialist options, but for ordinary loads trading down to an own brand is frequently a free saving. The honest test is to compare the price per wash and try one on your own laundry.
How can I tell which detergent is cheapest this week?
Use Rappn. You search a product and see every current offer across Coop, Migros, Aldi, Lidl, Denner, Otto's and Aligro at once, with the unit price, including per wash where available, next to the shelf price. Everything is filtered to your canton, you can set price alerts so you are told when a detergent goes on offer, and the app is free and neutral, with no commercial deals with retailers or brands. Since detergent is a frequent promotion item, checking live each week is the only reliable way to catch the lowest price.
