Shrinkflation Tracker Australia
Shrinkflation is when a product’s pack size is reduced without a corresponding cut in price, quietly raising the per unit cost. ShopHop tracks size and weight across Woolworths, Coles and Aldi and flags products where the unit price has risen because the pack got smaller.

Every product ShopHop tracks has its pack size and unit price recorded over time. When a size reduction pushes the per unit cost up, that change is highlighted, so a smaller pack at the same shelf price is recognised for what it is, a price rise per unit.
Why unit price is what matters
Comparing shelf prices alone can be misleading when pack sizes differ. ShopHop normalises to a per unit basis, such as per 100g or per litre, so you can compare value honestly. Read about unit pricing →
Frequently asked questions
Shrinkflation is when a product’s pack size is reduced without a matching reduction in price, so you pay more per unit for the same product. The shelf price can look unchanged even though the product got smaller.
