How it's calculated

Unit rate = price ÷ quantity
Saving = (higher rate − lower rate) ÷ higher rate

The unit rate is the price of one unit (a gram, a millilitre, a sheet), which makes different pack sizes comparable. Enter both quantities in the same unit. A bigger pack is not always cheaper per unit, which is why shelf labels show this number.
