Laundry hidden inflation: +14.5% per unit vs +2.0% official inflation

By ShrinkRadar · Updated 2026-11-05 · Part of the ShrinkRadar Index, recomputed from the case library and official price data on every build

When a laundry pack shrinks, its price per unit jumps. In 33 documented laundry shrinks with shelf prices before and after and an official match (2020–2026), the median price per unit changed +14.5%. Official inflation for the same cases, matched to each one’s category, country and time, was +2.0%: official prices up 2.0%, the ShrinkRadar per-unit price up 14.5% over the same periods.

Laundry in one line

Each line is computed from the tables below. Copy one with its source.

1. Laundry: official prices were up 2.0% and the ShrinkRadar per-unit price up 14.5% over the same periods. Packs that shrank cost a median 14.5% more per unit than the pack they replaced, against 2.0% official inflation for the same category, country and time (33 priced cases with an official match, 2020–2026).

2. In 88% of those laundry cases (29 of 33), the price per unit rose more than official inflation for the same category, country and time.

3. Across all 96 documented laundry shrinks since 2018, the size cut alone raised the price per unit by a median 10.8%, before any change in the shelf price.

By country

The same comparison for laundry cases by the country they come from, each against its own statistics office. A country needs at least 5 priced cases with an official match; 7 of 10 countries have fewer, and the table says so instead of showing a figure.

By year

By the year the pack changed. A year needs at least 5 priced cases; thin years are marked. Comparisons spanning several years (5 laundry cases) are left out of this series but kept in the headline and the case list.

The 96 laundry cases

Which cases count. All 96 laundry cases that changed in 2018 or later are listed and count in the size-cut figure. The per-unit headline uses the 33 that have shelf prices before and after and an official match (listed first). Left out of the per-unit figure: 59 size-only cases (the source recorded no shelf prices; we never fill one in), and 4 priced cases without an official match. Cases without an official match: no official benchmark loaded for this country (44). Not listed: 4 older laundry cases that changed before 2018, outside the range of the official data.

Official series used

Each laundry case is matched to one official series for its country. A broad match means no series exists for exactly this category, so the nearest wider one is used.
