👉 Listing math, also known as price listing or unit pricing, is a method used to compare the cost-effectiveness of different products by calculating the price per unit of a specific item, such as weight, volume, or quantity. This involves determining the total cost of the product and dividing it by the unit size (e.g., grams, liters, or pieces), then presenting this figure to help consumers understand the value they are getting for their money. For example, if a package of 500g of rice costs $10 and another package of 250g costs $7, listing math would show that the 250g package is more cost-effective per gram ($4/gram) compared to the 500g package ($4/gram), making it a better value despite the higher initial price. This approach aids consumers in making informed purchasing decisions by highlighting the true cost per unit of each product.
