Price premium, or relative price, is the percentage by which a product's selling price exceeds (or falls short of) a benchmark price. Marketers need to monitor price premiums as early indicators of competitive pricing strategies. Changes in price premiums can also be signs of product shortages, excess inventories, or other changes in the relationships between supply and demand. In a survey of nearly 200 senior marketing managers, 54 percent responded that they found the "price premium" metric very useful.
