- The mayonnaise-based meal averages €7.10 for four people, about 3% lower than 2024, while the vinegar-and-oil version is €5.93, down roughly 5%.

- IW economist Christoph Schröder reports pre-Christmas food prices have barely risen year-on-year, with vegetables, fruit, and meat even cheaper, easing the cost of homemade potato salad.
- The Kartoffelsalat-Index uses Rewe data and standardized four-person recipes for both styles, offering a simple benchmark that does not capture other retailers or recipe variations.
- Despite the dip from last year, costs remain above 2021 levels, and surveys show the dish remains the holiday favorite, cited by roughly a quarter to a third of respondents.
