Cart Abandonment Rate

The frequency in which customers add items to the online shopping cart, but do not complete their purchase. This can be calculated by dividing the total number of completed transactions by the number of initiated sales. Subtract the product from one and then multiply that by 100 to determine your abandonment rate (as a percentage). If an e-commerce store posted 5,000 sales in the last month and had 25,000 initiated shopping carts that did not result in a purchase, the result would be a 20% completion rate and an 80% cart abandonment rate.
