400 products had sales in your analysis period, but were not sold in the same period the previous year, these 400 products represent the innovation of the assortment.
Innovation rate = 25% = (400 / 1,600)
The range innovation rate indicator can be translated into English as "Innovation rate" or IPA Rate.
