Seven out of ten shoppers who add items to their cart will never complete the purchase. That number is not a rough estimate. Baymard Institute calculated it from 49 different studies: the average cart abandonment rate is 70.19% (Baymard Institute, 2024).
Think about what that means in revenue terms. Baymard estimates that $260 billion in lost orders could be recovered through better checkout design alone (Baymard Institute, 2024). Not through better ads. Not through more traffic. Just by fixing what happens after someone decides to buy.
This post breaks down the reasons behind that 70.19%, the research on what actually reduces it, and a practical priority list for e-commerce teams.
Why Shoppers Abandon Carts
Baymard's research identifies clear categories. Each one represents a different failure in the checkout experience.
Surprise Fees: 39% of Abandonments
The single biggest reason shoppers leave is unexpected costs. Shipping fees, taxes, or service charges that appear late in checkout drive 39% of all abandonments (Baymard Institute, 2024).
This is not complicated to understand. A shopper sees a product for $45, adds it to their cart, reaches checkout, and discovers the real total is $58. The trust gap between what they expected and what they are asked to pay creates immediate friction. Many will leave rather than accept the surprise.
The fix: Show all costs upfront. Display shipping estimates on product pages. Use a shipping calculator before checkout begins. If you offer free shipping above a threshold, make that visible early.
Required Account Creation: 28%
Nearly three in ten shoppers abandon because they are forced to create an account. They came to buy a product, not to join a membership program.
The fix: Guest checkout should be the default path, not a hidden option beneath the login form. You can invite account creation after the purchase is complete, when the customer has already committed.
Slow or Complicated Checkout: 21%
One in five shoppers leave because the process takes too long. Too many pages, too many form fields, unclear progress indicators.
The fix: Reduce form fields to the minimum required for the transaction. Use a single-page checkout where possible. Show a progress bar. Auto-fill where the browser supports it. Every additional step is a point where someone can decide the purchase is not worth the effort.
The average cart abandonment rate across e-commerce is 70.19%, based on 49 studies (Baymard Institute, 2024). Better checkout UX alone can improve conversion by 35.26% (Baymard Institute, 2024). Those two numbers frame the entire conversation about e-commerce
There are 9.7 million registered third-party sellers on Amazon. Only 1.9 million of them are actively selling (Marketplace Pulse, 2025).
That gap tells a story. Nearly 8 million sellers signed up, listed products, and then stopped. Some ran out of inventory. S
The product page is where money is made or lost. Every ad click, every organic search visit, every email campaign lands somewhere. For e-commerce, that somewhere is usually a product page. And if that page does not do its job, everything upstream was wasted sp
Trust Concerns: 18%
Eighteen percent of shoppers do not trust the site with their payment information. This is a design and credibility problem, not a security infrastructure problem.
The fix: Display recognized trust badges (SSL certificates, payment processor logos, security seals). Show clear return policies. Use familiar payment methods. Sites that look outdated or unprofessional trigger trust concerns regardless of their actual security.
Complicated Checkout: 17%
A checkout flow that confuses the shopper, asks for unnecessary information, or presents unclear error messages costs conversions. When someone cannot figure out how to complete the form, they leave.
The fix: Test your checkout with real users. Watch where they hesitate, where they make errors, where they re-read instructions. Simplify error messages. Label form fields clearly. Remove anything that is not strictly necessary.
The 35.26% Improvement Opportunity
Here is the number that should get every e-commerce team's attention: Baymard's research shows that better checkout UX can improve conversion rates by 35.26% (Baymard Institute, 2024).
That is not a theoretical ceiling. It is the measured improvement from applying usability best practices to the checkout flow. For a store doing $10 million in annual revenue, a 35% conversion improvement represents a significant revenue gain with no additional marketing spend.
Mobile vs. Desktop: Where Abandonment Hits Hardest
Mobile traffic now accounts for the majority of e-commerce visits, but mobile checkout remains harder. Smaller screens make forms more difficult to complete. Typing payment details on a phone keyboard introduces friction that desktop users do not face.
The principles are the same, but the execution matters more on mobile. Autofill support, digital wallet integration (Apple Pay, Google Pay), and minimal form fields have a disproportionate impact on mobile conversion rates.
If your analytics show a large gap between mobile and desktop conversion rates, your checkout flow is the first place to investigate.
A/B Testing Your Checkout
The abandonment reasons above are averages across the entire e-commerce industry. Your specific checkout has its own friction points. The only way to find them is to test.
Start with these high-impact tests:
Guest checkout vs. required registration. Measure the conversion difference directly.
Shipping cost visibility. Show estimated shipping on the product page vs. revealing it at checkout.
Number of form fields. Remove optional fields and measure the impact.
Payment options. Add digital wallets and measure whether conversion improves.
Progress indicators. Test a progress bar against no progress indicator.
Each test isolates one variable. Run them sequentially, not simultaneously, so you can attribute results clearly.
Recovery Strategies: Email, Retargeting, and Incentives
Preventing abandonment is the first priority. Recovering abandoned carts is the second.
Abandonment emails. A well-timed email sent within one hour of cart abandonment can recover a portion of lost sales. The most effective recovery emails include the specific items left in the cart, a clear call to action, and sometimes a small incentive (free shipping or a modest discount). Three-email sequences, sent at one hour, 24 hours, and 72 hours, generally outperform single emails. For the full sequence structure, timing, and benchmarks, see our e-commerce email marketing guide.
Retargeting ads. Showing the abandoned product in display or social ads keeps it visible. This works best for considered purchases where the shopper is still in the decision process, not for impulse buys where the moment has passed.
Exit-intent interventions. Detecting when a user is about to leave the checkout page (mouse moving toward the browser's close button on desktop, or back-button behavior on mobile) and offering a reason to stay. This could be a discount code, free shipping, or simply a reminder of what is in the cart. Use sparingly. Overuse trains shoppers to abandon deliberately for discounts.
Beyond Checkout: The Full Conversion Picture
Cart abandonment is the most measurable part of a larger conversion problem. Shoppers also leave at the product page (unclear pricing, poor images, missing information) and during browsing (slow page loads, confusing navigation, poor search results).

Tools for Tracking and Reducing Abandonment
Understanding your specific abandonment patterns requires data. Ooty Analytics connects your e-commerce data to AI assistants like ChatGPT, Gemini, and Claude, so you can ask questions about your checkout funnel in plain language instead of clicking through dashboard menus.
For product page improvements, our free SEO analyzer identifies technical issues that affect page speed and user experience, both of which influence whether a shopper reaches checkout in the first place.
The Priority Framework
If you are deciding where to start, this is the order that typically produces the fastest revenue impact:
Remove surprise fees. Show all costs before checkout. This addresses the 39% problem.
Enable guest checkout. One change, 28% of abandonment addressed.
Optimize for mobile. Digital wallets, larger touch targets, minimal typing.
Each fix compounds with the others. The 35.26% improvement Baymard measured comes from applying all of these together, not from any single change.
The $260 billion in recoverable revenue is not locked behind expensive technology or complex strategy. It is sitting in checkout flows that ask too much, reveal costs too late, and make buying harder than it needs to be. The fixes are known. The question is whether you will implement them.
