What Is Cart Abandonment?
Cart abandonment is one of the most studied problems in e-commerce. It describes the moment when a potential customer, having expressed clear purchase intent by adding a product to their shopping cart, navigates away from the site without completing their order.
The cart abandonment rate is calculated by dividing the number of completed purchases by the number of cart initiations, subtracting the result from one, and expressing it as a percentage.
Research consistently shows the global average abandonment rate is between 68% and 75%, meaning the majority of shopping sessions that progress to cart addition do not result in a sale.
For South African e-commerce businesses, this figure can be even higher due to factors specific to the local market, including high data costs on mobile devices, concerns about online payment security, limited payment method options (such as the absence of buy-now-pay-later solutions), and delivery costs that feel disproportionate relative to order values priced in rand.
Understanding why shoppers abandon carts is the first step to reducing the rate.
The most common reasons include unexpected shipping costs revealed at checkout, being required to create an account before purchasing, a slow or confusing checkout process, concerns about payment security, and simply using the cart as a wishlist without genuine intent to buy immediately.
Each of these causes has a specific fix, and addressing them systematically can meaningfully reduce abandonment and increase revenue without increasing advertising spend.
Cart abandonment data is tracked through analytics platforms such as Google Analytics 4, where e-commerce event tracking records add-to-cart and purchase events. The gap between these two events represents your abandonment. Segmenting abandonment data by device type, traffic source, and product category often reveals which audience segments or product lines have the worst abandonment and should be prioritised for improvement.
Cart Abandonment In Practice
A Pretoria-based online fashion retailer ran a three-month cart recovery programme after identifying that their abandonment rate was 74%, well above the industry average for apparel.
The programme included three components: an automated email sequence triggered one hour, 24 hours, and 72 hours after abandonment, retargeting ads on Meta showing the exact abandoned product, and an on-site exit-intent popup offering free delivery on orders over R800.
Within 90 days, the retailer recovered 12% of abandoned carts through the email sequence alone, with the retargeting campaigns adding another 4%. The combined effect added approximately R180,000 in monthly revenue that would previously have been lost.
Effective cart recovery relies on having the customer's email address or being able to identify them through cookies for retargeting. This is why many retailers now prompt for email early in the checkout process, even before the customer has filled in their full details.
Capturing the email address at step one of checkout means that even if the customer leaves at step two or three, the recovery sequence can still fire.
This single change, moving email capture to the very first checkout field, is one of the highest-impact optimisations available to any e-commerce business.
Common causes of cart abandonment
Most abandoned carts are not lost sales so much as interrupted ones, and the causes are predictable. The biggest is unexpected cost revealed late: delivery fees, taxes or surcharges that appear only at checkout. Others include being forced to create an account, a long or confusing checkout, limited or unfamiliar payment options, concerns about security, and slow pages, especially on mobile. Some abandonment is simply research, a shopper comparing before deciding. Knowing which cause dominates your store, usually visible in where people drop out, tells you what to fix first, because removing the single biggest friction point recovers more revenue than scattered tweaks.
How to reduce cart abandonment
Reducing abandonment means removing friction and rebuilding intent. Show all costs, including delivery, early rather than at the final step; offer guest checkout; keep the form short; and provide trusted, familiar payment options, which matters for South African shoppers weighing security. Make the page fast on mobile, where much abandonment happens. Then recover the carts you still lose: an abandoned-cart email sequence, reminding the shopper and sometimes offering help or an incentive, recovers a meaningful share of otherwise-lost sales. The order matters, fix the checkout friction first so fewer carts are abandoned, then use recovery emails to win back those that still are.
FAQ
What is a good cart abandonment rate?
The global average cart abandonment rate is approximately 70%, meaning only 3 in 10 shoppers who add to cart complete a purchase. Rates below 60% are considered strong for most retail categories. South African e-commerce sites often see higher rates due to shipping cost surprises and limited payment method options, so reducing abandonment is a major revenue opportunity.
How do you recover abandoned carts?
The most effective cart recovery methods are abandoned cart email sequences, SMS reminders, and browser push notifications sent within one to three hours of abandonment. Retargeting ads on Google and Meta showing the abandoned products also work well. Offering a small incentive, such as free shipping or a discount, in the follow-up can significantly improve recovery rates.
What is the average cart abandonment rate?
Across online retail it commonly sits around 70%, though it varies by device, product and price. A high rate is normal, since much of it is research rather than lost intent, so the goal is steady improvement against your own baseline rather than a universal target.
Do abandoned cart emails work?
Yes, they are among the highest-returning automated messages in ecommerce, because they reach a shopper who already chose a product. A short sequence, a reminder followed by help or a modest incentive, recovers a meaningful share of otherwise-lost sales.
