Your mobile checkout leaks 12 points more than desktop
Cart abandonment averages 70%, but mobile runs 77% vs 64.8% on desktop. The flow most of your buyers use gets the least optimization. Here's where to look.
The average online cart still gets abandoned 70% of the time – but the number that should worry you is the device split. Baymard Institute's 2026 analysis of 50 studies puts mobile abandonment at 77.0% versus 64.8% on desktop, a 12-point gap.
Most teams design and test the desktop flow first, then shrink it for phones. So the page where the majority of your traffic actually buys is the one that gets the least optimization attention. The usual culprits are forced account creation, too many form fields, no one-tap payment, and shipping or fees that only appear at the final step.
Pull up your own funnel on a phone and try to buy something. If checkout takes more than a few thumb taps, that 12-point gap is money you are leaving on the table – tightening the mobile path alone typically recovers 25–35% of abandoned carts.
