Discount statistics: how big are promotional discounts?
Since 2017 we have recorded 43,803 offers with an original price. The typical discount (median) against the original price is 33.3%. Of all offers recorded since 2017, 11.2% showed an original price. The archive holds 581,159 offers, the first one was recorded on 31 May 2015.
These are published offer prices from leaflets and retailer websites, not shelf prices and not a measure of general price changes.
Calculated on 4 November 2026. Newest recorded entry: 2 November 2026.
Discounts by sector and year
Typical discount (median) of offers with an original price, as a percentage of the original price. A value is shown only when the cell rests on at least 30 offers from at least 3 retailers and no retailer dominates, otherwise a dash is shown.

We analyse by the sector of the retailer because it is known for every offer. Product categories exist for only a small part of the offers and are not suitable for a discount statistic.
2026 is the current year, data as of 2 November 2026.

How the figures are made
What the figures are: published offer prices from leaflets and retailer websites, as we recorded them automatically. The discount is the difference between the crossed-out original price and the offer price, as a percentage of the original price.
What they are not: not shelf prices, not prices outside promotions and not a measure of inflation or price rises. We cannot check whether an original price was actually charged before.
We leave out offers with a discount below 1% or above 90%, because such extreme values could distort the result. This affects 83 of 43,886 offers with an original price.
A value is published only when it rests on at least 30 offers from at least 3 retailers (each with at least 5 offers and 2% of the cell) and no retailer accounts for more than 80% of the offers. Individual retailers are never named or compared.
The year is the year in which we recorded an offer. The retailers we record change from year to year, so differences between years do not show how retailer prices developed. Hidden entries and duplicate offers are not counted.
The full description is on the page Methodology.
For context, see the official consumer price index: CSO. We quote no figures from it and do not compare our values with it.
