Cart Abandonment
When an e-commerce shopper adds items to their cart but leaves without completing the purchase.
Cart abandonment is the e-commerce phenomenon where a shopper adds products to their shopping cart but leaves the website without completing the purchase. It is one of the most costly and most fixable revenue leaks in e-commerce.
Cart Abandonment Rate = (1 − Completed Purchases ÷ Cart Additions) × 100
At a global average of approximately 70%, cart abandonment is not a niche problem — it’s the default state of e-commerce. For every 10 shoppers who add to cart, 7 leave without buying. The question is never whether abandonment happens, but how much of it is avoidable.
Cart Abandonment Rate Benchmarks
| Segment | Average Abandonment Rate |
|---|---|
| Global average (all devices) | 70–71% |
| Mobile | 84–86% |
| Tablet | 80–81% |
| Desktop | 68–73% |
| Top-performing stores | 55–65% |
Mobile abandonment is dramatically higher than desktop — not because mobile shoppers are less willing to buy, but because mobile checkout has more friction: manual card entry, small form fields, and slower page loads on cellular connections.
By Industry
Abandonment rates vary significantly by product category:
| Industry | Abandonment Rate |
|---|---|
| Cruise / Ferry | ~98% |
| Finance / Insurance | ~83% |
| Non-profit donations | ~83% |
| Travel | ~82% |
| Fashion | ~68–72% |
| Consumer electronics | ~74% |
| Beauty & personal care | ~70% |
| Pet care | ~53% |
High-consideration, high-price categories (travel, electronics, finance) abandon more because the decision genuinely requires more time and research. Low-consideration, habitual purchase categories (pet food, beauty) abandon less. This matters for benchmarking: a 75% abandonment rate in travel is normal; in pet care it would warrant urgent investigation.
Why Shoppers Abandon Carts
Baymard Institute research across 2,000+ US consumers identifies these primary causes:
| Reason | % of Abandoners |
|---|---|
| Unexpected shipping / tax costs at checkout | 48% |
| “Just browsing, not ready to buy” | 43% |
| Site required account creation | 24–35% |
| Checkout process too long or complex | 18–27% |
| Couldn’t trust site with credit card info | 19% |
| Couldn’t see total order cost upfront | 14–17% |
| Website errors or crashes | 13–17% |
| Unsatisfactory returns policy | 15% |
| Insufficient payment options | 7–10% |
The first cause — unexpected costs — is a design choice, not a customer behaviour problem. Showing shipping costs on the product page or providing a shipping calculator in the cart eliminates the surprise entirely.
The second cause — “just browsing” — represents genuine research behaviour and is not fully recoverable. However, cart recovery emails convert a meaningful slice of these “not yet” visitors into buyers within 72 hours.
Cart Abandonment vs Checkout Abandonment
These are related but distinct metrics:
- Cart abandonment: Shopper adds to cart, never reaches checkout
- Checkout abandonment: Shopper reaches checkout, doesn’t complete payment
Checkout abandonment rates are typically lower (50–60%) but represent higher-intent visitors — they’ve invested time to begin the checkout process. Checkout abandonment is often more fixable through trust signals, payment option expansion, and form simplification.
Track both separately in your analytics. A high cart abandonment rate with a low checkout abandonment rate indicates the problem is before checkout (pricing, trust, urgency). High checkout abandonment with moderate cart abandonment points to friction within the checkout flow itself.
How to Reduce Cart Abandonment
Immediate wins (no A/B test required)
Show total cost before checkout. Display shipping costs on the product page or cart page — not only at the final checkout step. A “free shipping over $X” calculator on the cart page eliminates the most common cause of abandonment before it can occur.
Enable guest checkout. Forced account creation before purchase increases abandonment by 24–35%. Allow purchase as a guest; offer account creation post-purchase when the buyer already has a positive transaction experience.
Add Apple Pay and Google Pay. One-tap checkout eliminates the biggest friction point in mobile checkout — manual card entry. Stripe and PayPal data consistently shows 20–40% higher checkout completion rates when one-tap payment methods are available. On mobile, this is the single highest-ROI checkout fix.
Display trust signals at the payment step. An SSL badge, accepted payment logos (Visa / Mastercard / PayPal / Amex), and a visible money-back guarantee placed near the payment form directly address the “can I trust this site with my card?” hesitation.
Reduce checkout form fields. The average checkout form has 14.88 fields — the recommended minimum is 7–8. Audit every field: is it genuinely required to process the order? Address lookup (autocomplete from postcode) eliminates manual entry of the longest section.
Mid-term wins (A/B testing recommended)
- One-page vs. multi-step checkout (test by device — mobile and desktop often prefer different formats)
- Progress indicator display and wording
- Order summary visibility and placement during checkout
- Urgency signals: stock level, delivery date estimate, sale end countdown
- Payment method order and visual prominence
- Express checkout placement (above vs. below standard form)
Recovery tactics
Cart abandonment email sequence. A 3-email sequence (1 hour, 24 hours, 72 hours post-abandonment) typically recovers 5–15% of abandoned carts. The first email — sent within 60 minutes — is the most effective and requires no discount. Just a reminder. Emails 2 and 3 can introduce incremental incentives (free shipping, 10% off) to convert the more hesitant segment. Multi-email sequences generate 69% more orders than single messages.
Exit-intent popups. Triggered when cursor movement indicates imminent exit, a well-timed popup with a relevant offer (free shipping, a discount, or simply a reminder of what’s in the cart) recovers 3–7% of about-to-leave visitors. Best applied to new visitors; suppress for logged-in or repeat customers who find it intrusive.
Retargeting ads. 38% of abandoners report that they appreciate reminder ads after leaving a cart. Dynamic retargeting — showing the exact products left in the cart — outperforms generic brand ads by a significant margin for recovery intent.

The Financial Case for Fixing Cart Abandonment
At 70% average abandonment, checkout optimisation has an asymmetric ROI: traffic is already acquired, the shopper has already demonstrated purchase intent, and the fixes are specific and testable.
Example: A store doing $500,000/month in revenue with a 72% cart abandonment rate and $80 average order value. Reducing abandonment to 65% through checkout optimisation adds approximately $50,000/month in revenue from the same traffic — without increasing ad spend.
The Baymard Institute estimates that $260 billion in online orders are recoverable globally each year through better checkout design. This is not a small optimisation — it’s one of the highest-leverage activities in e-commerce CRO.
Checkout optimisation is among the highest-ROI work in a CRO programme. For a full checklist of what to audit, see Conversion Rate Benchmarks by Industry and Mobile Conversion Rate Optimization for mobile-specific checkout fixes.
Frequently Asked Questions
What is cart abandonment?
Cart abandonment occurs when an e-commerce shopper adds one or more products to their shopping cart but leaves the website before completing the purchase. The cart abandonment rate formula is: (1 - Purchases ÷ Cart Additions) × 100. The global average cart abandonment rate is approximately 70–71%, meaning 7 in 10 shoppers who add to cart do not buy.
What is a good cart abandonment rate?
The global average cart abandonment rate is 69–75% across e-commerce. Top-performing e-commerce stores achieve 55–65% abandonment rates through optimised checkout flows, trust signals, and friction reduction. If your cart abandonment rate exceeds 75%, checkout optimisation should be the first priority in your CRO programme.
What is the most common reason for cart abandonment?
Unexpected costs at checkout — primarily shipping fees and taxes not shown earlier in the flow — are the #1 reason for cart abandonment, cited by 48% of shoppers according to Baymard Institute research. The second most common reason is mandatory account creation before purchase (cited by 24–35% of abandoners), which is entirely preventable by enabling guest checkout.
How do you reduce cart abandonment?
The highest-impact cart abandonment reduction strategies are: (1) show total cost — including shipping and taxes — before checkout, (2) enable guest checkout and remove mandatory account creation, (3) reduce checkout form fields to the minimum required, (4) add trust signals at the payment step (security badge, accepted payment logos, money-back guarantee), (5) add Apple Pay and Google Pay to eliminate manual card entry on mobile, (6) send a 3-email cart recovery sequence at 1 hour, 24 hours, and 72 hours post-abandonment.
What is the cart abandonment rate on mobile?
Mobile cart abandonment rates average 84–86%, compared to 68–73% on desktop. The primary drivers of the mobile gap are manual card entry friction (eliminated by Apple Pay and Google Pay), small touch targets on checkout forms, and slower page load times on cellular connections. Adding one-tap payment methods is consistently the highest-ROI single fix for mobile checkout abandonment.
How much revenue is lost to cart abandonment?
Globally, cart abandonment represents approximately $260 billion in recoverable lost orders annually (Baymard Institute). For an individual store, calculate your recoverable opportunity as: (monthly cart additions × abandonment rate × average order value × realistic recovery rate of 5–15%). A store with 5,000 monthly cart additions, 72% abandonment, $80 AOV, and 10% recovery rate has $28,800/month in recoverable revenue.
