What does this tool do?
Unit price divides the package price by its size, making different formats comparable. It is the fairest way to compare value when the packaging differs.
The Formula
Unit price = Package price ÷ Package sizeFrequently Asked Questions
Is a bigger package always cheaper per unit?
No. Discounts and promotions can make a smaller pack cheaper per unit, so check the figure rather than the pack size.
What if the sizes use different units?
Convert them to a common unit first, for example 1 lb = 16 oz. The calculator does not convert between unit types.
