What is the Unit Price Index?
The Unit Price Index is a monthly view of the best recorded unit price for everyday staples. It makes package sizes easier to compare on the same basis.
How is the Unit Price Index calculated?
For each staple, Dealophant takes every product in that category with a confident unit count that it recorded a price for during the month, measures all of them in the category's usual unit, and reports the lowest price per unit. The change compares that figure with the previous month and is shown only when both months have at least three comparable products in the same unit.
