“The package looks the same. The price is the same. But there's less inside. That's shrinkflation.”
What is shrinkflation?
Shrinkflation is when a manufacturer reduces the amount of product in a package while keeping the shelf price the same. A bag of chips that was 10 ounces is now 9.5 ounces — same bag design, same price, 5% less food. It's a form of inflation that doesn't show up in the sticker price.
Why manufacturers do it
When input costs rise — ingredients, packaging, labor, fuel — manufacturers face a choice: raise the price or shrink the product. Consumer psychology research shows shoppers are more sensitive to price changes than to size changes. A bag that costs $4.99 stays $4.99; most people don't notice it now holds less.
How to spot it
Compare the unit price (price per ounce or per pound) on shelf labels over time. If the unit price rises but the sticker price stays flat, the product has shrunk. TALLY's Shrinkflation Observatory tracks documented size changes across grocery categories.
