What Is an Abandoned Cart? Reasons, Recovery, and Mistakes to Avoid
Sirazum Monir Osmani
An abandoned cart basically means a shopper adds products to their online cart but leaves without buying them.
Cart abandonment is a common challenge for eCommerce businesses. Shoppers may abandon their carts because of unexpected shipping costs, complicated checkout processes, slow delivery, payment failures, or concerns about purchasing from an unfamiliar store. Others may simply be comparing products without intending to buy immediately.
According to Baymard Institute's cart abandonment research, the average cart abandonment rate is approximately 70%. However, not every abandoned cart represents a customer who was ready to purchase.
For eCommerce businesses, the challenge is understanding which shoppers can be encouraged to complete their purchases and which problems are preventing them from doing so. By identifying the reasons behind cart abandonment, improving the checkout experience, and implementing targeted recovery strategies, online retailers can reduce lost sales and improve conversion rates.
What Is Cart Abandonment?
Cart abandonment is when a shopper adds products to an online shopping cart but leaves without completing a purchase, creating a gap between shopping interest and sales.
An abandoned cart can occur at any point after a customer adds an item to their cart. However, an abandoned checkout occurs when a shopper begins the checkout process but leaves before completing payment.
This distinction matters because customers who reach checkout have progressed further through the purchase journey. Their reasons for leaving may also be different from those of someone who abandoned a cart before reviewing shipping or payment details.
The cart abandonment rate measures the percentage of created shopping carts that do not result in completed purchases. It is calculated by subtracting completed purchases from created carts, dividing the result by created carts, and multiplying by 100.
For eCommerce marketers, monitoring cart abandonment alongside checkout completion and eCommerce conversion rates helps identify where potential customers are dropping off. Understanding the main causes of cart abandonment is the next step toward improving those metrics.
What Are the Reasons for Cart Abandonment?
Reasons for cart abandonment include unexpected charges, frustrating checkout steps, unclear delivery terms, payment trouble, technical errors, and trust concerns that interrupt the decision to buy.
The main reasons for cart abandonment are listed below:
Unexpected Extra Costs
Complicated Checkout
Forced Account Creation
Delivery Problems
Unclear Shipping Information
Security, Trust, and Return Policy Concerns
Payment Failures
Website Errors
Bad Return Policies
Declined Cards
Unexpected Extra Costs
Unexpected costs and high shipping fees cause cart abandonment by making the final price feel higher than expected, especially when taxes and service charges appear late.
Customers generally evaluate products based on their displayed prices. When shipping fees, taxes, or additional service charges appear only at the final checkout step, the resulting price difference can discourage them from completing their purchases.
This makes price transparency important throughout the shopping journey. Your eCommerce store should communicate the estimated total order cost as early as possible, rather than introducing additional charges immediately before payment.
If your store offers free shipping above a certain order value, display the free-shipping threshold clearly on product and cart pages. This helps shoppers understand their options before proceeding to checkout.
Complicated Checkout
A complicated checkout and forced account creation cause cart abandonment by making shoppers complete unnecessary tasks before payment, especially when the checkout flow feels slow or confusing.
Excessive checkout steps, unnecessary form fields, and confusing navigation can turn a straightforward purchase into a frustrating experience.
The problem becomes more noticeable during mobile checkout, where customers must complete forms on smaller screens. Checkout flows that offer very few payment options can create additional obstacles.
For eCommerce businesses, simplifying the checkout flow means removing unnecessary steps, keeping instructions clear, and making the purchase process easy to complete.
Providing guest checkout, express payment options, and a consistent mobile experience can help customers move from cart to payment with fewer interruptions.
Forced Account Creation
Forced account creation causes cart abandonment by asking shoppers to register before purchasing, adding an unwanted commitment when they may only want to place a single order.
A customer who is ready to buy a product may not want to create a password, verify an email address, or complete a registration process before making the purchase.
Forced registration introduces an additional requirement that is separate from the customer's original intention.
Offering guest checkout allows shoppers to complete their purchases without creating an account. Retailers can still invite customers to register after checkout, when doing so will no longer interrupt the immediate purchasing decision.
Delivery Problems
Delivery problems and unclear shipping information cause cart abandonment by leaving shoppers uncertain about arrival dates, shipping options, or whether their order will arrive when needed.
Slow delivery times can discourage customers who need products within a particular timeframe. This is especially relevant for seasonal purchases, gifts, and products associated with time-sensitive occasions.
Customers may also abandon their carts when estimated delivery dates are unavailable or when the available shipping options cannot meet their expectations.
Providing a realistic shipping estimate helps shoppers evaluate whether the purchase suits their needs. Your shipping policy should also explain applicable fulfillment timelines, delivery methods, and possible delays before customers reach the payment stage.
Unclear Shipping Information
Unclear shipping information causes cart abandonment by hiding delivery charges, geographic restrictions, or estimated arrival dates until shoppers have already invested time in the checkout process.
Even when delivery itself is reliable, missing information can create uncertainty.
For example, shoppers may want to know whether their location is eligible for delivery, if shipping charges vary by region, or whether their order qualifies for free shipping.
When these details remain unclear, customers may hesitate to proceed because they cannot confidently evaluate the final purchase.
eCommerce stores should make shipping information accessible from product pages and shopping carts, with updated delivery estimates wherever the customer's location is known.
Security, Trust, and Return Policy Concerns
Security, trust, and return policy concerns cause cart abandonment by making shoppers question whether their payment details, personal information, or purchase will be handled responsibly.
Online shoppers must trust a store before sharing sensitive information or completing a transaction. This can be particularly challenging for unfamiliar brands without an established customer relationship.
Missing contact information, unclear privacy practices, questionable reviews, or unfamiliar payment interfaces can increase these concerns.
Displaying genuine customer reviews, recognizable trust badges, and clear contact information can help establish credibility. Stores should also use secure payment systems and explain how customer information is protected.
Transparent return policies provide additional reassurance by clarifying what happens if a product does not meet expectations.
Payment Failures
Payment failures cause cart abandonment by blocking otherwise willing buyers at the final step, often because of payment gateway errors, timeouts, or unsupported payment methods.
A customer may have already selected products, entered delivery information, and attempted payment when the transaction fails.
Possible causes include an unresponsive payment gateway, slow page speed, interrupted network connections, or temporary payment processing errors.
These issues require technical attention because abandoned-cart messages cannot resolve an underlying checkout malfunction.
Retailers should monitor payment success rates, investigate recurring failures, and offer alternative options such as digital wallets where appropriate.
Giving shoppers a reliable alternative can help them complete the purchase without restarting the entire checkout process.
Website Errors
Website errors cause cart abandonment by preventing customers from navigating to checkout, reviewing product details, or submitting orders when pages freeze or important elements stop working.
Broken links, unexpected error messages, missing product information, and malfunctioning checkout buttons can prevent customers from completing transactions.
These problems may affect certain devices, browsers, or payment methods, making them difficult to identify without regular testing.
Poor website performance can also increase abandonment when pages load slowly or become unresponsive during checkout.
eCommerce teams should review checkout errors, monitor website performance, and test purchasing journeys across different devices. Recurring technical problems should be corrected at their source rather than addressed solely through abandoned-cart emails.
Bad Return Policies
Bad return policies cause cart abandonment by increasing the perceived risk of buying, particularly when eligibility rules, return costs, or refund timelines are difficult to understand.
Customers may hesitate to buy clothing, electronics, cosmetics, or other products when they are unsure what will happen if an item is unsuitable.
A restrictive return policy can make that hesitation stronger, particularly when the customer must pay expensive return shipping fees or navigate a complicated approval process.
To reduce uncertainty, communicate the return window, product eligibility, return conditions, and associated costs clearly.
Your refund policy should also explain how refunds are processed and when customers can expect their money to be returned.
Declined Cards
Declined cards cause cart abandonment by interrupting payment despite clear purchase intent, sometimes because of outdated card details, bank restrictions, or automated fraud checks.
A customer might encounter a "card declined" message because of an incorrect card number, expired card, insufficient funds, or restrictions imposed by their bank.
Although some declined transactions cannot be resolved by the merchant, the checkout experience can still help customers understand what to do next.
Clear error messages, opportunities to correct payment details, and alternative payment methods can help shoppers continue without unnecessary frustration.
For eCommerce retailers, providing payment flexibility is an important part of reducing cart abandonment caused by otherwise avoidable transaction problems.
Is It Possible to Reduce Cart Abandonment Before It Happens?
Yes, it is possible to reduce cart abandonment before it happens by clarifying costs and delivery, simplifying checkout, supporting convenient payments, and improving mobile usability.
Effective checkout optimization focuses on removing the obstacles customers encounter while making a purchase.
Transparent pricing, guest checkout, simplified forms, reliable delivery information, and visible trust signals can improve checkout completion. Express checkout and mobile optimization can further reduce the time and effort required to place an order.
However, prevention and recovery serve different purposes.
Prevention improves the shopping experience so fewer customers leave unnecessarily. Recovering abandoned carts, on the other hand, focuses on reconnecting with customers who have already left.
eCommerce businesses benefit from combining both approaches rather than relying exclusively on recovery campaigns to compensate for checkout problems.
How to Recover Abandoned Carts?
You can recover abandoned carts without discounts by addressing the likely objection, reinforcing product value, reassuring shoppers about delivery or security, and simplifying their return to checkout.
Abandoned cart recovery involves encouraging shoppers who left without purchasing to return and complete their orders.
However, offering discounts immediately is not always necessary. Some customers simply need delivery reassurance, stronger social proof, greater payment flexibility, or help resolving a technical problem.
The most effective approach combines improvements to the shopping experience with relevant follow-up communication.
The following practices can help your eCommerce business prevent avoidable abandonment and recover more purchases.
Show Shipping, Taxes, Fees, and Other Charges Before Checkout
This means presenting the estimated total purchase cost before the final payment stage. Transparent pricing prevents unexpected charges from discouraging customers, while measuring checkout completion before and after pricing changes helps retailers evaluate their effectiveness.
Reduce the Number of Checkout Steps and Enable Guest Checkout
Shorten the purchasing process by removing unnecessary pages and decisions. A streamlined checkout with an accessible guest option allows customers to complete orders without registration or unnecessary navigation.
Minimize Form Fields and Add Autofill
Ask customers only for the information necessary to process their orders. Browser autofill, address suggestions, and appropriate field validation can reduce typing effort and prevent errors, particularly among mobile shoppers.
Offer Multiple Payment Options
Provide payment methods that match customer preferences and regional availability. Depending on your market, these may include credit cards, debit cards, digital wallets, and other locally supported methods, giving customers alternatives when their preferred method is unavailable.
Display Estimated Delivery Dates and Shipping Costs
Show realistic delivery dates and available shipping options before payment. Providing this information helps shoppers evaluate the purchase and prevents disappointment when delivery expectations do not match their needs.
Make Account Creation Optional
Allow customers to finish their purchases without registering for an account. You can encourage account creation after purchase by explaining benefits such as easier order tracking, saved addresses, and faster future checkouts.
Add Recognizable Payment-Security Indicators
Display legitimate security indicators and familiar payment provider information where customers enter payment details. These signals can increase confidence in the checkout process, particularly for first-time buyers who are unfamiliar with your store.
Clearly Explain Returns, Refunds, and Payment Security
Make your return policy, refund timelines, and payment security information easy to find. Clear explanations reduce purchase uncertainty and reassure customers who might otherwise leave to investigate these details elsewhere.
Automatically Preserve Cart Contents After Payment or Website Errors
Configure your eCommerce platform to retain or restore cart information whenever technically possible. Preserving selected products and applicable checkout details helps customers resume purchasing without repeating earlier steps after an unexpected interruption.
Send Cart-Recovery Messages With a Direct Link Back to Checkout
Use automated email, SMS, WhatsApp, or other appropriate channels to reconnect with shoppers who have abandoned their carts. Personalize messages with relevant product information, address likely objections, and include a direct link to the saved cart or checkout so customers can return with minimal effort.
For example, a shopper who leaves after reviewing delivery options may respond better to shipping reassurance than a discount. Another shopper who encountered a payment error may benefit more from a reminder highlighting an alternative payment method.
This is why recovery messages should reflect available customer behavior and context rather than applying the same incentive to every abandoned cart.
How to Measure Cart Abandonment and Recovery?
Cart abandonment and recovery are measured using cart creation, completed purchases, eligible abandoned carts, and recovered orders, with revenue metrics showing whether recovery efforts produce value.
Measuring cart abandonment helps eCommerce businesses understand how many shopping journeys fail to result in purchases. Recovery measurement evaluates how many of those abandoned carts eventually convert.
Although related, these metrics answer different questions.
Cart Abandonment Rate Formula
Cart Abandonment Rate (%) = [(Created Carts − Completed Purchases) ÷ Created Carts] × 100
For example, suppose your online store records 1,000 created carts and 300 completed purchases during a defined measurement period.
Cart Abandonment Rate = [(1,000 − 300) ÷ 1,000] × 100 = 70%
This means 70% of the measured carts did not result in completed purchases.
To calculate the rate accurately, track unique carts and the purchases associated with them using consistent measurement rules. Exclude invalid activity, such as bot-generated carts, where identifiable.
Cart Recovery Rate Formula
Cart Recovery Rate (%) = (Recovered Abandoned Carts ÷ Eligible Abandoned Carts) × 100
For example, if your business identifies 500 eligible abandoned carts and successfully recovers 75 of them:
Cart Recovery Rate = (75 ÷ 500) × 100 = 15%
The recovery rate indicates the proportion of eligible abandoned carts that eventually result in recovered orders.
Eligible carts should be defined consistently based on factors such as the abandonment window, customer reachability, and recovery eligibility.
Beyond these two metrics, eCommerce marketers should monitor the financial contribution of recovery activities.
Revenue per recovered cart measures the revenue generated from recovered purchases divided by the number of carts successfully recovered. It helps businesses understand the value of recovery rather than evaluating performance solely through the number of completed orders.
Campaign ROI evaluates whether the incremental financial contribution from recovery activities justifies their costs. When calculating ROI, consider messaging expenses, discounts, software fees, and the potential impact on profit margins.
Other useful indicators include checkout completion rate, recovery-message click-through rate, purchase conversion after engagement, and revenue attributed to each marketing channel.
For accurate performance reporting, distinguish orders that were genuinely influenced by recovery campaigns from customers who may have returned and purchased independently.
Tracking these metrics over time helps your CRM and lifecycle marketing teams identify which recovery approaches are effective, where further optimization is necessary, and how to avoid mistakes that reduce profitability.
What Mistakes to Avoid While Recovering Abandoned Carts?
Mistakes to avoid while recovering abandoned carts include sending generic reminders, relying excessively on discounts, contacting customers too frequently, ignoring technical problems, and measuring recovery performance incorrectly.
The following mistakes can limit the effectiveness of abandoned cart recovery campaigns:
Sending the Same Message to Every Customer: Generic recovery messages ignore differences in customer behavior, purchase intent, and possible reasons for abandonment. Personalize communication based on available cart information, customer history, and the stage at which the shopper exited.
Offering Discounts Too Early: Automatically offering discounts can reduce profit margins and encourage customers to delay purchases in anticipation of future offers. Start with relevant product information, reassurance, or assistance before considering whether an incentive is necessary.
Sending Too Many Recovery Messages: Excessive reminders across email, SMS, and other channels can frustrate customers and lead to unsubscribes. Establish reasonable contact limits, coordinate communication across channels, and stop recovery messages once a purchase is completed.
Ignoring the Reasons Behind Cart Abandonment: Sending reminders without finding why a customer abandoned a cart can leave the original purchasing obstacle unresolved. Analyze checkout behavior, payment failures, delivery concerns, and customer feedback to identify issues your business can address.
Using Broken Recovery Links: A recovery message loses much of its value if customers cannot return to their carts or must repeat the entire checkout process. Test recovery links regularly and ensure they direct shoppers to an accessible cart or checkout whenever supported by your platform.
Failing to Address Technical Checkout Problems: Recovery campaigns cannot compensate for persistent payment errors, broken checkout buttons, or an unreliable website. Resolve these problems first so returning customers can successfully complete the purchases they previously attempted.
Ignoring Customer Consent and Preferences: Contacting shoppers through channels they have not agreed to use can damage trust and create compliance risks. Respect applicable consent requirements, communication preferences, and opt-out requests when configuring recovery campaigns.
Measuring Every Returning Purchase as Recovered Revenue: Not every shopper who returns after abandoning a cart does so because of a recovery message. Use consistent attribution rules and, where practical, controlled comparisons to estimate the actual contribution of recovery campaigns.
Avoiding these mistakes requires businesses to understand customer behavior before deciding how, when, and whether to intervene.
How to Find Out Why a Customer Abandoned a Cart?
To find out why a customer abandoned a cart, examine checkout behavior, compare customer segments, investigate error logs, and collect feedback rather than relying on assumptions.
Start by analyzing the checkout funnel to identify where customers stop progressing toward a purchase.
For example, a high drop-off rate immediately after shipping costs appear may indicate pricing or delivery concerns. A sharp increase in abandonment at the payment stage may suggest payment failures, limited payment methods, or trust-related hesitation.
However, behavioral patterns provide clues rather than definitive explanations. A customer leaving after viewing shipping information does not necessarily mean that shipping costs caused the abandonment.
To develop a clearer understanding, segment your conversion funnel by device type, traffic source, product category, customer type, cart value, and checkout stage.
These segments can reveal differences that overall cart abandonment figures may conceal.
For instance, if mobile customers abandon checkout more frequently than desktop users, your team should investigate form usability, page loading times, and mobile payment experiences.
Similarly, if first-time buyers abandon their carts more often than returning customers, reviewing trust signals, delivery information, and registration requirements may help identify possible barriers.
Use eCommerce analytics to examine these patterns. Platforms such as Google Analytics 4 support events including add_to_cart, begin_checkout, and purchase, allowing businesses to analyze progression through the purchasing journey when tracking is configured correctly.
Combine this information with payment gateway logs, website error reports, customer support queries, and direct feedback.
Customer engagement platforms like Markopolo AI can also use shopping activity and behavioral information to support more contextual recovery communication.
For eCommerce managers, the objective is to move beyond identifying how many carts were abandoned and understand which abandonment patterns can be addressed through better checkout experiences or more relevant customer engagement.
How Does Markopolo AI Help With Abandoned Cart Recovery?
Markopolo AI helps with abandoned cart recovery by detecting abandonment events in real time, using cart contents and customer behavior to personalize recovery messages, and automating follow-ups across multiple marketing channels.
The platform uses first-party customer data and behavioral signals to help eCommerce businesses understand shopping activity and deliver more relevant communication when a customer leaves without purchasing.
Once abandonment is identified, Markopolo AI can activate automated recovery journeys across email, SMS, WhatsApp, push notifications, and AI voice, depending on the store's integration and available customer contact information.
Instead of treating every abandoned cart as the same event, these journeys can account for the products customers considered, their engagement history, and available behavioral context.
For example, a returning customer who abandons checkout after reviewing a product may receive communication that reinforces product value or provides useful purchase information. Another customer experiencing payment difficulties may benefit from a recovery message that explains available payment options and directs them back to checkout.
This approach supports both cart recovery and abandoned checkout recovery without requiring every shopper to receive the same sequence of messages.
Markopolo AI can also help eCommerce teams automate lifecycle communication and track revenue attribution across marketing channels. These capabilities make it easier to evaluate recovery performance alongside broader customer engagement efforts.
However, successful recovery still depends on resolving the underlying reasons for abandoned carts. A personalized message cannot fix an unreliable payment gateway, an unnecessarily complicated checkout, or unclear delivery policies.
For eCommerce businesses, reducing cart abandonment requires a combination of checkout improvements, customer understanding, and relevant recovery communication. Addressing these areas together can improve purchase completion while protecting the customer experience and the profitability of recovered sales.
