Cart abandonment rate
Cart abandonment rate is the percentage of online shopping sessions in which a visitor adds at least one item to the cart but leaves without completing an order.
Also known as: shopping cart abandonment, checkout abandonment rate, basket abandonment
Cart abandonment rate measures how many shoppers who show buying intent — by putting something in the cart — do not finish the purchase. It is one of the most watched metrics in e-commerce because it sits right at the end of the funnel: these visitors have already been acquired, have found a product and have started to buy.
The most widely cited benchmark comes from the Baymard Institute, which averages documented abandonment rates from 50 different studies. Its figure is 70.22%, meaning roughly two in three shoppers who add to cart leave without ordering. The individual studies in that average range from 57.6% to 81.1%, a spread that shows how much the number depends on industry, device, traffic mix and how the metric is measured.
Not all abandonment is a problem to solve. Many visitors use the cart as a wish list, compare prices or are simply browsing. The goal is therefore not zero abandonment but removing the avoidable reasons — surprise costs, forced account creation, a long or confusing checkout — that turn ready buyers away.

The standard formula is: cart abandonment rate = (1 − completed orders ÷ sessions with an add-to-cart) × 100. If 1,000 sessions added an item to the cart and 280 resulted in an order, the abandonment rate is (1 − 280 ÷ 1,000) × 100 = 72%.
Definitions vary in two important ways. First, some tools count carts created rather than sessions, so a returning visitor who completes a purchase on a second visit may count as both an abandoned and a converted cart. Second, “checkout abandonment” is a narrower measure that starts when a visitor begins the checkout, not when they add to cart. Checkout abandonment is lower than cart abandonment and is more directly influenced by the checkout design. Always state which definition you use when comparing to benchmarks.
Why shoppers abandon
Baymard's survey research separates shoppers who were “just browsing” from those who intended to buy, and asks the latter why they left. The recurring reasons are extra costs that appear late (shipping, taxes and fees), being required to create an account, slow delivery, not trusting the site with card details, a long or complicated checkout, not being able to see the total cost up front, website errors, and an unsatisfactory returns policy.
These reasons are notable because most of them are design and policy decisions the store controls. Baymard's large-scale usability testing finds that the average checkout contains more form fields than needed and that many sites still fail basic usability guidelines, which is part of why the global average has barely moved over 14 years of tracking.
Benchmarks: use them carefully
The 70.22% benchmark is an average of averages. It is useful as a sanity check — if your rate is 40% you may be measuring differently, and if it is 90% something may be broken — but it is not a target. Mobile traffic usually abandons more than desktop; high-consideration purchases such as travel and furniture abandon more than low-cost repeat purchases; and stores with heavy social-media traffic see more casual browsing.
The most reliable benchmark is your own history. Track the rate weekly by device and traffic source, and measure changes after each checkout improvement. A drop of a few percentage points on a large store can be worth far more than a new acquisition campaign.
Recovering abandoned carts
Two complementary approaches exist. Prevention improves the checkout so fewer people leave: showing total costs early, offering guest checkout, reducing form fields, displaying trust signals and supporting common payment methods and wallets. Recovery brings people back after they leave: reminder emails for known customers, retargeting ads, and saved carts across devices.
Recovery emails work only when the shopper has given an email address and consent rules allow contact, which in Europe usually means GDPR and ePrivacy requirements apply. Prevention scales to every visitor and is usually the better first investment.
Connecting the metric to revenue
To make the metric meaningful for management, translate it into money. Multiply the number of sessions with an add-to-cart by the average order value and by the percentage-point improvement you expect. For example, a store with 20,000 add-to-cart sessions a month, an average order value of €60 and a two-point reduction in abandonment would gain about 400 orders, or roughly €24,000 a month. State the assumptions explicitly, since this is an estimate rather than a measured result.
Mistakes to avoid when tracking abandonment
The most common mistake is changing the definition halfway through a reporting period, for example switching analytics tools or moving from cart-based to session-based counting. The rate will jump or fall for reasons that have nothing to do with shoppers. Keep a written definition and annotate any tracking change on your dashboard.
A second mistake is reading the rate without volume. If a new social campaign brings many casual browsers, abandonment rises even though the checkout did not get worse, and total orders may actually increase. Always review abandonment next to add-to-cart sessions, orders and revenue.
A third mistake is treating every abandoned cart as lost revenue. Some shoppers return later on another device or buy in a physical store. Recovery and prevention efforts should be judged by the change in completed orders, not by the theoretical value of all abandoned carts.

Conversion rate: the share of all sessions that end in an order. Average order value: revenue divided by the number of orders. Guest checkout: buying without creating an account. Recovery email: a reminder sent to a known shopper who left items in the cart, subject to consent rules.
How this glossary entry was compiled
Every number on this page links to the organisation that published it: an independent research firm, an official product or pricing page, a public filing, or official documentation. We do not publish our own estimates as facts, and where a figure is reported by the company it describes, it is labelled company-reported. Prices are taken from official vendor pages and change often, so open the linked source before relying on one. If a widely repeated figure could not be traced to a primary source, we left it out. Entries are reviewed when the underlying sources publish new editions, and the update date at the top of the page shows the latest review.
Examples
Fashion store with late shipping fees
Shipping appears only on the final step. Showing a shipping estimate on the product page and in the cart removes the most common surprise-cost reason for leaving.
Electronics shop requiring accounts
Every buyer must register before paying. Adding guest checkout, with an optional account after the order, addresses one of the top abandonment reasons in Baymard's surveys.
Mobile-heavy beauty brand
Most traffic comes from social apps on phones. Adding wallet payments and shortening the address form reduces typing on small screens.
How to reduce cart abandonment
A practical sequence from measurement to testing.
- 1Measure consistently. Pick one definition (cart or checkout abandonment) and track it weekly by device and traffic source.
- 2Find where people leave. Use funnel reports to see which checkout step loses most visitors.
- 3Show total cost early. Display shipping, taxes and fees in the cart, not only on the last step.
- 4Offer guest checkout. Let first-time buyers pay without creating an account.
- 5Cut form fields. Remove optional fields, combine name fields and use address autocomplete.
- 6Add payment options and trust signals. Support popular cards and wallets, and show security and returns information near the payment button.
- 7Test and recover. A/B test each change and set up consented reminder emails for known customers who leave.
Frequently asked questions
What is a good cart abandonment rate?
There is no universal target. Baymard's 70.22% average is a reference point; compare mainly against your own history by device and channel.
Is cart abandonment the same as checkout abandonment?
No. Checkout abandonment starts when a shopper begins checkout and is usually lower than cart abandonment.
What is the main cause of cart abandonment?
Among shoppers intending to buy, unexpected extra costs such as shipping and fees are consistently the most cited reason in Baymard's surveys.
