Value market share, also known as value market share, represents the share of a product measured in monetary terms rather than by volume. It is a key indicator for assessing a player’s performance in the market. When products vary in price, value market share provides a more accurate measure of a company’s economic impact. For example, Champagne’s value market share is more than twice its volume market share in the sparkling wine market because its average selling price is significantly higher than that of other products in the same category.
