The Quick Answer
Cart abandonment rate is the percentage of online shoppers who add items to their cart but leave the site without completing the purchase.
Cart abandonment rate is a conversion metric that measures how many potential sales are lost between the "add to cart" action and the completed order. It is one of the most important metrics in e-commerce because it directly quantifies lost revenue.
The formula is:
Cart Abandonment Rate = (Carts Created - Completed Purchases) / Carts Created x 100
If 5,000 shopping sessions created a cart this month and 1,350 resulted in completed purchases, your abandonment rate is (5,000 - 1,350) / 5,000 x 100 = 73%. That means nearly 3 out of 4 shoppers who showed buying intent walked away.
Industry Benchmarks
The average cart abandonment rate across all e-commerce is approximately 69.82%, based on Baymard Institute's meta-analysis of 49 different studies spanning multiple years and markets. This is the most widely cited figure in the industry.
Abandonment rates vary by sector and device:
| Segment | Typical Abandonment Rate |
|---|---|
| All e-commerce (average) | 69-70% |
| Fashion / apparel | 68-74% |
| Travel | 80-85% |
| Airlines | 87-90% |
| Finance / insurance | 75-80% |
| Non-profit / charity | 60-65% |
| Desktop | 65-70% |
| Tablet | 70-75% |
| Mobile | 75-85% |
Travel and airline sites have the highest rates because shoppers frequently compare prices across multiple sites before booking. Non-profits have the lowest because donors who reach the payment page have strong intent.
Worked Example: Calculating Abandonment and Revenue Impact
An online home goods store has the following monthly data:
| Metric | Value |
|---|---|
| Shopping carts created | 5,000 |
| Completed purchases | 1,350 |
| Average cart value | $85 |
Cart Abandonment Rate = (5,000 - 1,350) / 5,000 x 100 = 73%
Abandoned carts = 5,000 - 1,350 = 3,650
Potential lost revenue = 3,650 x $85 = $310,250
Result: 73% abandonment rate with $310,250 in potential lost revenue.
Now calculate the impact of recovering just a fraction:
| Recovery Rate | Recovered Carts | Additional Revenue |
|---|---|---|
| 5% | 183 | $15,555 |
| 10% | 365 | $31,025 |
| 15% | 548 | $46,580 |
| 20% | 730 | $62,050 |
Even a modest 10% recovery rate -- achievable with abandoned cart emails and checkout optimization -- adds $31,025 per month in revenue. Annually, that is $372,300 from a relatively straightforward set of improvements.
Why Shoppers Abandon: The Data
Baymard Institute's checkout usability research identifies the top reasons shoppers give for abandoning during checkout. The percentages represent how often each reason is cited (respondents could select multiple reasons):
| Reason | Frequency |
|---|---|
| Extra costs too high (shipping, tax, fees) | 48% |
| Site required creating an account | 26% |
| Checkout process too long or complicated | 22% |
| Could not see or calculate total order cost upfront | 21% |
| Delivery was too slow | 18% |
| Did not trust the site with credit card information | 17% |
| Returns policy was unsatisfactory | 12% |
| Not enough payment methods | 11% |
| Credit card was declined | 4% |
The single biggest cause -- unexpected costs -- is responsible for nearly half of all abandonment. This is a solvable problem. Showing shipping costs, taxes, and fees early in the browsing experience (not just at the final checkout step) removes the sticker shock that drives shoppers away.
Recovery Strategy 1: Abandoned Cart Emails
Abandoned cart email sequences are the most proven recovery tactic. Data from email platforms like Klaviyo and Omnisend shows:
- Open rate: 40-45% (vs. 15-20% for standard marketing emails)
- Click-through rate: 10-15%
- Recovery rate: 5-15% of abandoned carts
Recommended Sequence
Email 1 (1 hour after abandonment): Simple reminder. "You left something in your cart." Include cart contents with images and a direct link back to checkout. No discount yet.
Email 2 (24 hours): Address common objections. Highlight free returns, customer reviews, or shipping policy. Still no discount.
Email 3 (72 hours): Final reminder. If appropriate, offer a small incentive (5-10% off or free shipping). Create mild urgency ("Your cart will expire soon").
This three-email sequence typically recovers 2-3x more carts than a single email. The first email captures high-intent shoppers who got distracted. The second and third catch those who need more convincing.
Recovery Strategy 2: Checkout Optimization
Address the structural causes of abandonment:
Offer Guest Checkout
Forced account creation causes 26% of abandonment. Always offer guest checkout. You can invite customers to create an account after purchase, when the friction cost is lower.
Show All Costs Upfront
Display shipping estimates on product pages or in the cart -- not just at the final checkout step. "Free shipping on orders over $50" works as both a cost-transparency measure and an average-order-value booster.
Simplify the Checkout Flow
Baymard Institute's research found the average e-commerce checkout has 23 form elements, but only about 12 are necessary. Every unnecessary field increases abandonment. Use autofill, smart defaults, and address lookup to minimize typing.
Offer Multiple Payment Methods
11% of shoppers abandon because their preferred payment method is not available. At minimum, offer credit cards, PayPal, and mobile wallets (Apple Pay, Google Pay). Buy-now-pay-later options like Klarna or Afterpay can reduce abandonment for higher-priced items.
Display Trust Signals
17% of shoppers cite payment security concerns. SSL badges, recognizable payment logos, customer reviews, and clear contact information build trust. These elements matter more for lesser-known brands than for established retailers.
Recovery Strategy 3: Exit-Intent Offers
Exit-intent popups detect when a user's cursor moves toward the browser's close button and display a message. Common approaches:
- Offer free shipping or a small discount
- Remind the user of items in their cart
- Show limited-time availability
- Collect email for a cart recovery sequence
Exit-intent offers typically recover 3-5% of abandoning visitors. They are less effective on mobile (where cursor tracking is not possible), but equivalent techniques like back-button triggers can serve a similar purpose.
Reducing Abandonment by Device
Mobile deserves special attention because it accounts for a growing share of e-commerce traffic but has significantly higher abandonment rates (75-85% vs. 65-70% on desktop).
Mobile-specific optimizations:
- Larger tap targets -- buttons and form fields should be at least 44x44 pixels
- Mobile wallet support -- Apple Pay and Google Pay reduce checkout to a single tap
- Autofill and address autocomplete -- minimize keyboard input
- Progress indicators -- show users where they are in the checkout flow
- Fast page load -- every additional second of load time increases mobile abandonment. Google research found that mobile pages taking over 3 seconds to load see significantly higher bounce rates.
Measuring Progress
Track abandonment rate weekly or monthly alongside these supporting metrics:
- Checkout start rate -- percentage of visitors who begin checkout (vs. just adding to cart)
- Checkout completion rate -- the inverse of abandonment rate at the checkout stage
- Cart recovery rate -- percentage of abandoned carts recovered via emails or retargeting
- Revenue per visitor -- combines traffic, conversion, and average order value into a single number
Improvements compound. Reducing abandonment from 73% to 68% on 5,000 monthly carts with an $85 average value means 250 additional completed orders -- an extra $21,250 per month.
FAQ
What is a normal cart abandonment rate?
The average cart abandonment rate across all e-commerce is approximately 69-70%, according to Baymard Institute's meta-analysis of 49 different studies. This means roughly 7 out of 10 shoppers who add items to their cart leave without completing the purchase. Rates vary by industry and device, with mobile abandonment rates typically 5-10 percentage points higher than desktop.
How do I reduce cart abandonment?
The most effective strategies are: offer guest checkout (forced account creation causes 26% of abandonments), show all costs upfront including shipping and taxes, simplify the checkout to fewer steps, offer multiple payment methods, display trust signals like SSL badges and reviews, and send abandoned cart recovery emails. Addressing hidden costs alone can significantly reduce abandonment.
Do abandoned cart emails work?
Yes. According to data from email marketing platforms like Klaviyo and Omnisend, abandoned cart emails achieve open rates of 40-45% and click rates of 10-15%, far above standard marketing emails. Recovery rates of 5-15% of abandoned carts are typical. A three-email sequence (sent at 1 hour, 24 hours, and 72 hours after abandonment) tends to perform best.
Why is cart abandonment so high?
Many shoppers use the cart as a browsing and comparison tool rather than a commitment to purchase. Beyond this browsing behavior, the top actionable reasons include unexpected costs at checkout (shipping, taxes, fees), required account creation, complex checkout processes, concerns about payment security, and slow delivery options.
How do I calculate cart abandonment rate?
Cart Abandonment Rate = (Carts Created - Completed Purchases) / Carts Created x 100. If 5,000 shopping carts were created in a month and 1,350 resulted in completed purchases, the abandonment rate is (5,000 - 1,350) / 5,000 x 100 = 73%.
Does free shipping reduce cart abandonment?
Yes, significantly. Unexpected shipping costs are the number one reason for cart abandonment, cited by about 48% of shoppers who abandon. Offering free shipping -- even with a minimum order threshold -- directly addresses this. If free shipping is not feasible, showing shipping costs early in the browsing experience reduces sticker shock at checkout.
What is the revenue impact of cart abandonment?
The impact is substantial. If a store has 5,000 abandoned carts per month with an average cart value of $85, that represents $425,000 in potential lost revenue. Even recovering 10% of those carts would add $42,500 per month. Globally, cart abandonment represents an estimated $4+ trillion in lost e-commerce revenue annually.
Is mobile cart abandonment higher than desktop?
Yes. Mobile cart abandonment rates are typically 75-85%, compared to 65-70% on desktop. Smaller screens, harder form entry, slower page loads, and less trust in mobile payment security all contribute. Optimizing the mobile checkout experience -- larger buttons, autofill, mobile wallets like Apple Pay -- can reduce the gap.
Should I offer a discount to recover abandoned carts?
Use discounts cautiously. A small discount (5-10%) in the second or third recovery email can help convert price-sensitive shoppers. However, routine discounts train customers to abandon on purpose to receive a coupon. Reserve discounts for genuinely at-risk orders and focus first on removing friction rather than adding incentives.
How does checkout length affect cart abandonment?
Complex or lengthy checkouts cause about 22% of abandonment according to Baymard Institute research. The average large e-commerce checkout has 23 form elements, but only about 12 are actually necessary. Reducing form fields, enabling autofill, and offering one-page checkout can meaningfully reduce abandonment from this cause.
