Roughly seven out of every ten online shopping carts are abandoned before purchase.
That number has barely moved in almost twenty years, which tells you the problem is not technology. It is human behavior, and a short list of avoidable friction.
TL;DR
- The average cart abandonment rate is 70.22 percent, based on Baymard Institute’s meta-analysis of 50 studies.
- The top actionable reason is unexpected extra costs like shipping, tax, and fees, cited by 39 percent of abandoning shoppers.
- Mobile abandonment rates are around 80 percent versus roughly 70 percent on desktop.
The abandonment figures here come from Baymard Institute, the most widely cited authority on checkout behavior.

Why people walk away
Extra costs are the top actionable cause, followed by slow delivery and trust or forced-account friction. Note the pattern: most of these are avoidable.
A surprise shipping fee at the final step, a forced account signup, or a checkout with too many fields each sends a ready-to-buy customer away.
Why the rate never improves
The striking fact is stability.
The 70 percent figure has stayed roughly the same since 2006, because better checkout technology has not fixed a problem rooted in buyer psychology.
Many abandonments are simply window shopping, people using the cart to check a total or save an item.
But a large, recoverable slice comes from fixable friction, which is why Baymard estimates better checkout design can lift conversion by around a third.
The single biggest lever is transparency on cost: surprise fees at checkout are the number one killer, which is why “free shipping” is not a giveaway but a conversion tool. The mobile gap matters too.
Since mobile drives most traffic in these markets but abandons at around 80 percent, the mobile checkout is where the most revenue leaks.
The durable insight is that cart abandonment is not a mystery; it is a predictable response to friction, and most of that friction is self-inflicted.

Most people who put something in an online cart do not buy it.
The biggest reason is being surprised by extra costs like shipping at the last moment.
This has been true for almost twenty years, because it is about how people feel, not about the technology.
