While specific data on the average checkout abandonment rate for Shopify stores is not publicly available, industry research indicates that the average cart abandonment rate across e-commerce is approximately 70%.
This figure encompasses both cart and checkout abandonment, as many studies do not differentiate between the two stages. It's important to note that abandonment rates can vary based on factors such as device type, with mobile users exhibiting higher rates than desktop users.
To gain a more accurate understanding of your store's performance, it's advisable to monitor your own checkout abandonment metrics within Shopify's analytics tools.
