Cart abandonment occurs when a shopper adds items to an online shopping cart but leaves the website before finishing the transaction. This metric helps retailers understand purchase intent and identifies friction points in the checkout experience. Reducing this rate directly increases revenue without requiring additional marketing spend on new traffic.
What is cart abandonment?
Cart abandonment is the failure of a potential customer to complete a purchase after starting the checkout process. In ecommerce, any item placed in a virtual basket that does not result in a finished transaction is considered abandoned. High abandonment rates often indicate a broken sales funnel or a poor user experience on mobile and desktop devices.
To measure this, retailers use the Cart Abandonment Rate. This is calculated by dividing the total number of completed transactions by the total number of initiated transactions. Marketers may also define it as [the ratio of abandoned carts to initiated transactions] (Wikipedia).
Why cart abandonment matters
Monitoring this metric is essential for diagnosing the health of an ecommerce site. While some abandonment is natural, high rates suggest deep-seated issues with site performance or pricing strategy.
- Identifies revenue leaks: Most large-sized ecommerce sites can achieve a [35.26% increase in conversion rates] (Baymard Institute) by improving checkout design.
- Signals user experience flaws: Frequent drop-offs on specific pages, like the shipping information screen, highlight technical bugs or confusing layouts.
- Reveals market competitiveness: Online shoppers often compare at least five different websites and [consult 10 different information sources] (Muster, R. F. / Wikipedia) before making a final decision.
- Measures massive financial impact: Across the US and EU, poorly designed checkouts contribute to roughly [$260 billion in recoverable lost orders] (Baymard Institute).
How to reduce cart abandonment
Reducing abandonment is an iterative process of testing and optimization rather than a one-time fix.
- Analyze drop-off points: Use web analytics to see exactly where users leave the funnel. If 25% of users drop off on the second page of a cart, that page likely contains a friction point like high order values or complex forms.
- Create a hypothesis: Determine why the user left. Is it a lack of trust, high costs, or a technical error?
- Implement A/B testing: Use experimentation tools to test solutions. You can show half your visitors the original page and the other half a version with a progress bar or guest checkout to see which version completes more sales.
- Monitor benchmarks: While site-specific goals are best, it is helpful to know that [the average documented online cart abandonment rate is 70.22%] (Baymard Institute).
Common reasons for abandonment
The reasons for walking away from a cart fall into two categories: natural browsing behavior and checkout friction. [Around 43% of US online shoppers abandon] (Baymard Institute) simply because they were window shopping or not ready to buy.
Beyond "just browsing," the main causes include:
- High extra costs: Unexpected shipping, taxes, or fees are the top reason for abandonment, driving away [39% of shoppers] (Baymard Institute).
- Forced account creation: Many users feel pressured to sign up and will leave if a guest checkout option is unavailable.
- Checkout complexity: Complicated processes frustrate users with short attention spans. The [average US checkout contains 23.48 form elements] (Baymard Institute), which is significantly higher than the ideal 12 to 14.
- Lack of trust: Shoppers often hesitate to provide credit card info to unfamiliar sites without clear security indicators or social proof.
- Password fatigue: A study found that [one-third of online purchases were abandoned] (MasterCard / University of Oxford) because customers could not remember their account passwords.
Best practices
Implement these strategies to keep shoppers in the funnel and improve overall throughput.
- Show total costs upfront: Avoid sticker shock by displaying shipping fees and taxes early in the process.
- Minimize form fields: Reduce the number of required form elements by 20% to 60% to speed up the process.
- Provide guest checkout: Allow users to finish their purchase without the commitment of creating a permanent account.
- Add social proof: Include reviews, testimonials, and trust seals on product and checkout pages to build credibility.
- Offer multiple payment methods: Ensure popular options like PayPal or Amex are available to cater to local and personal preferences.
- Improve site speed: Optimize checkout code to ensure pages load quickly, preventing technical frustration.
Shopping cart recovery
Recovery strategies aim to bring customers back after they have left the site. Even with a well-optimized checkout, [typical abandonment rates remain between 60% and 80%] (Dynamic Yield).
Abandoned cart emails
If a user provided their email address before leaving, you can send an automated reminder. These emails often include a coupon code or a limited-time offer to incentivize the shopper to return.
Retargeting ads
Retargeting uses an ad pixel on the checkout page to show ads to the shopper as they browse other sites or social media. This keeps your brand top-of-mind even if you do not have the user's email address.
Common mistakes
Mistake: Hiding shipping costs until the final step. Fix: Offer flat-rate shipping or a shipping calculator early in the cart experience.
Mistake: Requiring a complex registration process to buy. Fix: Implement a "Guest Checkout" or social login to reduce friction.
Mistake: Ignoring technical performance on mobile devices. Fix: Regularly audit the mobile checkout flow for bugs, crashing, and slow-loading scripts.
Mistake: Assuming all abandoned carts are lost sales. Fix: View some abandoned carts as "wish lists" or research tools, then use that data to retarget the visitor later.
FAQ
How do you calculate the cart abandonment rate? You divide the total number of completed sales by the total number of initiated checkouts. For example, if 500 people start a checkout and 100 finish, the completion rate is 20% and the abandonment rate is 80%.
What is a good cart abandonment rate? While the industry average is over 70%, [the best-optimized checkout processes achieve a rate of 20%] (Saleh and Shukairy). Each site has a unique audience, so you should focus on improving your own baseline.
Do "just browsing" customers count as abandonment? Yes, they are included in the metric. However, because [43% of shoppers are only researching] (Baymard Institute), you cannot eliminate abandonment entirely. Marketers should focus on the issues they can control, like price transparency and site design.
Can A/B testing help with abandonment? A/B testing is the primary way to reduce abandonment. By testing changes like adding a progress bar or changing the color of the "Buy Now" button, you can use math to prove which version results in fewer abandoned carts.
Why do users add items to a cart if they don't intend to buy? Many users use the cart as a comparison tool to see the total price with shipping or as a way to organize items they want to save for later. Some also do it for "entertainment value" or boredom.
