Roughly seven in ten online carts never turn into a completed order. The most-cited figure, from Baymard Institute's running average of 50 separate studies, puts documented cart abandonment at 70.22%. It's an alarming number, and it's the reason your inbox fills with tools promising to win those shoppers back with a discount code and a follow-up email.
Here's the part most owners get backwards. A large share of that 70% was never going to buy, and no email will change that. The part you can actually recover is usually sitting inside your own checkout, losing orders to problems you can measure and fix. Chase the wrong half and you spend money teaching your best customers to wait for a coupon.
Baymard's survey found that 42% of US shoppers abandon a cart simply because they were browsing, comparing prices, or saving something for later. That behavior is normal. You cannot design it away, and you shouldn't try to.
So the honest version of the question isn't "how do I stop 70% of people from leaving." It's narrower: of the shoppers who genuinely wanted to buy, how many did your site turn away? That number is much smaller, far more fixable, and it's the only one worth chasing.
When Baymard asked shoppers who abandoned for a reason (rather than just browsing), the answers fall into four buckets. Extra costs like shipping, tax, and fees topped the list at 40%, with another 12% saying they couldn't see the total cost up front. That isn't a psychology problem. It's a pricing-transparency problem you control.
The next bucket is friction: 18% left because the site forced them to create an account, and 17% because checkout was too long or complicated. Then trust: 19% didn't trust the site with their card details, and 13% weren't happy with the returns policy.
And then the bucket almost every guide skips: plain technical failure. 17% of shoppers abandoned because the website had errors or crashed, 10% because their card was declined, and 9% because there weren't enough payment methods. Those aren't shoppers who changed their minds. They're orders your store dropped on the floor.
This is the gap in most cart-abandonment advice. It opens with "send a recovery email," which only ever reaches people after they've already left. Before you spend a cent on that, look at the orders failing in real time.
Take declined payments. Some declines are genuine fraud. Many are not: legitimate cards wrongly rejected by an over-cautious rule somewhere in the payment chain. Stripe reported that it recovered a record $6 billion in falsely declined transactions in 2024 alone, and cited industry estimates that these false declines cost US retailers around $81 billion in lost sales in 2023. If even a slice of your "card declined" abandonments are false declines, that's revenue you already earned and handed straight back.
Errors and crashes work the same way. A checkout that breaks on one browser, a specific payment method, or under mobile load doesn't announce itself. The shopper just leaves, and you see a slightly worse conversion rate with no idea why. That's engineering territory, and it's why we tend to treat conversion as an engineering problem rather than a marketing one.
Once the leaks are sealed, the highest-return fixes line up neatly with the reasons above.
Show the full price early. Since surprise costs are the single biggest reason people bail, putting shipping and tax in view before the final step removes the shock that kills the order.
Offer guest checkout. Forcing account creation costs you almost one in five would-be buyers over a login they never asked for.
Shorten the form. Baymard's benchmark found the average US checkout shows 23.48 form elements when an ideal flow needs only about 12 to 14. Every field you cut is one less reason to give up. Add the wallets and payment methods your customers actually use, and make sure the whole thing works cleanly on a phone, where more of your traffic checks out than you probably assume.
Check that it works without a mouse too. A field a screen reader cannot announce loses the order in the same silent way a crash does, and since June 2025 it carries legal exposure on top, which is why accessibility belongs in the checkout audit rather than in a separate compliance folder.
None of this is exotic. It's the difference between a checkout built around your business and one built around the shopper.
Here's the part that separates stores that fix abandonment from stores that just read about it: you have to see where the money leaks before you can plug it.
Most stores can tell you their overall conversion rate and almost nothing about the steps in between. You want to know how many carts reach the shipping step, how many reach payment, how many payments fail and why, and where mobile diverges from desktop. Baymard estimates that better checkout design alone can lift conversion by as much as 35.26% on large sites, but only if you know which change to make. If you want to put a dollar figure on even a small lift, our conversion rate calculator does the math for you. Wiring up that instrumentation is usually a modest e-commerce development job, and it pays for itself the first time it catches a broken payment path.
Abandoned-cart emails aren't useless. For the genuinely distracted shopper, the one who got interrupted with a full cart and real intent, a well-timed reminder works. The mistake is reaching for them first, and reaching for a discount every single time. Do that and you train your most loyal customers that patience pays, so they start abandoning on purpose. Save recovery flows for the honest "life got in the way" abandons, once the checkout itself is sound.
If your abandonment rate feels high and no one can tell you exactly where orders are dying, that's the kind of problem we dig into at Encomage. Our work usually starts by instrumenting the checkout and watching real sessions fail before we change anything, because guessing at conversion is expensive and the leaks are almost always measurable.
