Checkout Completion Rate by Device Benchmarks
On Shopify, 44% of mobile checkouts finish, against 49% on desktop (Littledata). This page covers top-decile targets, splits by vertical, and the friction points that make up most of the mobile gap.
Checkout Completion Rate by Device
The share of started checkouts that end in a placed order, reported separately for mobile, desktop and tablet sessions.
Checkout completion rate is orders divided by checkout starts. Splitting it by device shows whether shoppers struggle to reach checkout or struggle to finish it once they get there. On Shopify, Littledata's benchmark puts the average at 44% on mobile and 49% on desktop. The metric only counts shoppers who have already shown strong intent by starting checkout. That makes it a cleaner signal of checkout friction than overall conversion rate or cart abandonment, because those two also absorb browsing behaviour and traffic quality.
Checkout completion is the last stage of the cart abandonment funnel. Baymard Institute's meta-analysis of 49 studies puts average cart abandonment at 70.19%. That figure starts counting at add-to-cart, so it is a longer funnel than checkout start to order.
Most stores in the €1M to €15M band now get over three-quarters of their sessions from phones. In Dynamic Yield's 2024 dataset, mobile made up 75% of device usage. That means a 5 to 10 point mobile completion gap usually costs more than any desktop problem you could fix.

| Add-to-cart rate | 6.31% | 5.81% | 6.15% | Dynamic Yield, 2025 |
| Session conversion rate (global) | 2.88% | 2.37% | 2.85% | Dynamic Yield, rolling 12 months, 2026 |
| Session conversion rate (Shopify) | 1.2% | 1.9% | n/a | Littledata |
| Session conversion rate (cross-industry) | 2.0% | 3.4% | n/a | Contentsquare |
The pattern is consistent. Mobile shoppers add to cart as often as desktop shoppers, or more often: 6.31% vs 5.81% in Dynamic Yield's 2025 data. They then lose ground at checkout. On Shopify, the gap at checkout is about 5 points on average, and Cartylabs sees 10 to 15 points between devices within the same store.
The gap is shrinking. Cartylabs estimates that mobile conversion was a third of desktop's in 2021 and is now around half to two-thirds, mostly thanks to Shop Pay, Apple Pay and Shopify's mobile checkout updates. In Littledata's 2026 panel, the best stores actually complete more checkouts on mobile than on desktop.

The jump from average to top decile is bigger than the gap between devices. If your mobile completion is 44%, the 20+ points available from reaching top-decile execution matter far more than the 5 points needed to match your desktop rate.
Checkout completion by vertical and device
Vertical changes both the size of the gap and the cause. Replenishment categories like beauty, supplements and coffee have many returning buyers whose details are already saved, so the mobile gap is small. High-AOV categories like furniture, electronics and jewellery show the opposite: shoppers research on their phones and often finish on a laptop.
No public panel yet reports checkout completion by vertical and device together. The table below is our directional model built from the sourced device averages above. Use it to sense-check your own numbers, not as a citation.
Estimated checkout completion by vertical and device (Metricuno estimate modelled from the sources above, directional only)
| Vertical | Mobile share of sessions | Mobile completion | Desktop completion | Gap (pts) |
|---|---|---|---|---|
| Beauty and personal care | ~80% | 45 to 50% | 50 to 55% | ~5 |
| Food, drink and supplements | ~75% | 47 to 52% | 52 to 57% | ~5 |
| Fashion and apparel | ~78% | 40 to 45% | 48 to 53% | ~8 |
| Electronics and accessories | ~60% | 36 to 41% | 48 to 53% | ~12 |
| Home and furniture | ~65% | 34 to 39% | 46 to 51% | ~12 |
| Jewellery and luxury | ~70% | 31 to 36% | 44 to 49% | ~13 |
A rule of thumb: once AOV rises above roughly €150, expect the mobile gap to widen. People are reluctant to type card details on a phone for a big purchase, and they are more likely to switch devices before paying. That switch looks like mobile abandonment in GA4 unless you track users across devices.
Check your measurement before you fix your checkout
Express wallets such as Shop Pay, Apple Pay and PayPal can skip the begin_checkout event, which inflates completion rates. Some analytics setups count iPads as desktop, and a missing GA4 consent signal can hide whole device segments. Dynamic Yield's global data even shows mobile converting better than desktop by session (2.88% vs 2.37%), while Shopify data shows the reverse (1.2% vs 1.9%). Definitions matter as much as performance, so compare like for like.
The friction points behind the mobile gap
Surprise costs come first. In Baymard's 2024 survey, 48% of shoppers who abandoned blamed extra costs such as shipping, taxes and fees. On a phone, the order summary is often collapsed, so the first time shoppers see the full total is at the payment step.
Forced account creation (26% in Baymard's survey) and a long or complicated checkout (22%) hurt more on mobile, where every extra field is another keyboard switch. Missing autofill attributes, address lookup that doesn't work, and numeric fields that open a text keyboard all add to the drop-off.
Payment is the biggest lever. Typing a 16-digit card number with a CVC on a phone is where mobile shoppers drop out, and this is why express wallets have narrowed the gap. If Apple Pay or Shop Pay only appears below the fold at the payment step, you're throwing away most of that benefit.
Speed adds to all of this. A widely cited Google finding is that 53% of mobile visitors leave a page that takes over 3 seconds to load. Third-party scripts from heatmaps, A/B testing tools and review widgets often load on checkout-adjacent pages, and they hurt slower phones much more than desktop.
What good looks like for your store
For a Shopify store doing €1M to €15M, aim for at least 50% blended completion, keep mobile within 5 points of desktop, and treat mobile above 60% as a top-quintile result. If mobile is below 40%, you have a fixable checkout problem rather than a traffic problem.
To find the leak, break the funnel into steps (information, shipping, payment) for each device, then look at the step where mobile drops most compared with desktop. Importing your historical GA4 data lets you set this baseline on day one, without waiting weeks for new data.
Checkout completion rate by device: FAQ
On Shopify, Littledata's average is 44% on mobile, and the top 10% of stores exceed 64%. In Littledata's 2026 panel, the top decile reached 82%. If you're above 55% on mobile, you're doing well. Below 40%, start with payment and form friction.
Mobile shoppers face harder form entry, card numbers typed on small keyboards, collapsed order summaries that hide the total, and slower page loads. Many also research on a phone and then buy on a laptop, which shows up as mobile abandonment unless you track users across devices.
Cart abandonment starts at add-to-cart and averages 70.19% (Baymard). Checkout completion starts at checkout start and averages about 45% on Shopify (Littledata). Completion measures checkout friction alone, while abandonment also includes shoppers who were never really ready to buy.
Divide purchases by begin_checkout events for each device category over the same period. In GA4, build a funnel exploration with device category as a breakdown. Make sure express-wallet purchases fire both events, or your figures will be inflated.
Tablets usually bring in less than 10% of sessions, and their completion rates sit close to desktop: 45 to 55% in Cartylabs' 2026 ranges. Check whether your analytics labels iPads as desktop. Otherwise, they rarely deserve their own optimisation work.
Yes. Express wallets are the main reason Cartylabs estimates the mobile conversion gap has shrunk from about 3x in 2021 to 1.5 to 2x. They work best when they appear at the top of the first checkout step and on the cart, not only at payment.
High-AOV categories such as jewellery, furniture and electronics show the widest gaps, because shoppers often switch to desktop for big purchases. Replenishment categories such as beauty and supplements show the smallest, because returning customers have their details saved.
Usually, yes. In Baymard's 2024 survey, 26% of shoppers who abandoned said a forced account was the reason. Offer guest checkout by default, and ask shoppers to create an account on the order confirmation page instead.
They can. Every third-party script adds to load time, and mid-range phones feel it most. Audit what loads on the cart and checkout pages, and combine tools where you can so you load one lightweight snippet rather than several.
Fewer shoppers reach checkout than visit product pages, so tests take longer to reach significance. A store with 2,000 mobile checkout starts per week usually needs 3 to 4 weeks to detect a 5% relative lift. Test bigger changes, such as wallet placement, rather than small copy tweaks.
