The cart abandonment rate shows the percentage of abandoned shopping carts before completing a purchase. It indicates the correlation between the number of abandoned shopping carts and the number of initiated transactions. This metric helps marketers understand the behavior of visitors on a particular website.
It is calculated by dividing the total number of completed transactions by the total number of initiated transactions. This rate will identify what percentage of visitors add an item to the cart but don’t complete the purchase.
