How to calculate the cart abandonment rate?
The cart abandonment rate is calculated using the formula: (carts created - carts completed) / carts created x 100. For example, if 1,000 carts are created and 300 are completed, the abandonment rate is 70%. The average cart abandonment rate in e-commerce is between 69% and 70%.
Understanding cart abandonment rate in detail
The cart abandonment rate measures the percentage of visitors who add products to their cart without completing the purchase. It is one of the most revealing indicators of e-commerce performance, as it highlights friction points in the buying journey. A high rate signals obstacles between purchase intent and final conversion, representing significant lost revenue for online merchants.
The formula is straightforward: (number of carts created - number of carts completed) / number of carts created x 100. This calculation gives you a percentage reflecting the proportion of visitors who abandoned their cart before placing an order. It is recommended to track this metric on a weekly or monthly basis to identify trends and measure the impact of your optimizations.
The main causes of cart abandonment are well documented: hidden fees that appear late in the checkout process, an overly complex checkout with too many steps, mandatory account creation to complete the purchase, and shipping times perceived as too long. Each of these friction points can be identified and addressed through detailed funnel analysis.
To effectively reduce your abandonment rate, it is essential to segment it by traffic source, device type, and product category. An e-commerce analytics tool like Fullmetrix allows you to visualize this data in real time, pinpoint friction points precisely, and measure the impact of each optimization on your overall conversion rate.
Worked example
An e-commerce site records 1,000 carts created over one month. Of these, 300 are completed with a purchase. The cart abandonment rate is therefore: (1,000 - 300) / 1,000 x 100 = 70%. This result is in line with the industry average (69-70%), but means that 700 carts were abandoned, potentially representing thousands of dollars in lost revenue.
