What is Abandoned cart rate?

Abandoned Cart rate is a metric that measures the number of customers who added items to their cart, initiated the checkout process, but didn’t complete the purchase. This metric reflects the amount of money lost due to potential customers not buying any items and leaving. The formula to calculate Abandoned Cart rate is the number of Abandoned Carts divided by the total number of shoppers who add items to their cart. An example of an Abandoned Cart rate would be if 10 customers added items to their carts, but only 8 of them completed their purchases, the Abandoned Cart rate would be 10% (2/10).

Formula

Abandoned Cart rate = Number of Abandoned Carts/Number of Shoppers Who Added an Item to the Cart *100

Example

If 10 customers add items to their shopping cart and 2 of those customers don’t complete their purchase, then the Abandoned Cart rate would be: 2/10 * 100 = 20%.
