Is Aldi cheaper than Walmart in the USA?

Usually, yes: Aldi is often cheaper than Walmart in the USA for a typical grocery basket, especially if you compare Aldi’s store-brand items with Walmart’s comparable store-brand items.

That said, the gap is not fixed. Depending on your region and the specific items you buy, Walmart can match or beat Aldi on some products—especially name brands, larger package sizes, and non-grocery items.

A practical rule of thumb:

• Aldi is often best for basic groceries and store-brand staples.
• Walmart is often better if you want a wider selection, more name brands, or to combine groceries with household, pharmacy, or general merchandise purchases.

Aldi’s low prices come with tradeoffs like fewer choices, a heavy emphasis on private-label products, and a smaller-store format. Aldi also commonly uses a cart-deposit system and self-bagging, which helps keep costs down.
