Shrinkflation Check Guide

Your favourite cereal, coffee, or snack feels lighter than it used to be — but the price is the same. That's shrinkflation: a quiet price hike hidden inside the pack. This tool quantifies exactly how much you're losing.

How to use it

  1. Old pack — the price, quantity, and unit of the product as it used to be. Check old receipts, old photos of the pack, or ask around.
  2. New pack — the price, quantity, and unit of the product as it is now. Read it off the current pack.
  3. If the price hasn't changed, enter the same number in both price fields.

Real example — Cereal shrinkflation

Old pack (last year):
Cereal 500g at $4.99
New pack (now):
Cereal 425g at $4.99
  1. Old price: 4.99, New price: 4.99
  2. Old quantity: 500, New quantity: 425
  3. Both units: g
LootLens tells you:
Old PPU: $0.010/g → New PPU: $0.012/g Hidden hike: +17.6% — you're paying 18% more per gram.
Pro tip: The most common shrinkflation trick is keeping the pack dimensions the same but reducing the fill level. Weigh it on a kitchen scale if you suspect foul play. Common offenders: cereal, coffee, snacks, detergent, chips.
