What Is Cart Abandonment? Definition, Causes and What You Can Fix

Cart abandonment happens when a shopper adds items to a cart but leaves without completing the purchase. The average cart abandonment rate is 70.22% across 50 studies (Baymard Institute, 2025), so an unfinished cart is common rather than proof that your store failed.

The cart can be part of shopping rather than a commitment to buy. Someone may be comparing delivery costs, checking a product combination or saving items for later, so the cart's value is not automatically revenue you could have collected.

That distinction matters when deciding what to repair and whom to contact. An anonymous cart gives you a behavior to study, while a checkout with contact information may give you a practical recovery opportunity.

Checkout abandonment concerns a shopper who began the checkout process but did not complete the order. It is a narrower stage than adding to cart, and its denominator should be checkout starts rather than all carts.

An abandoned checkout is incomplete for more than ten minutes after the customer entered an email (Shopify Help Center, 2026). That definition connects the record to an identifiable checkout, not every visitor who selected an item.

Do not mix a cart abandonment rate from an analytics tool with a count of abandoned checkout records in Shopify. They can differ because they cover different behaviors, use different identities and close the measurement window differently.

Choose the definition before comparing periods. If your team switches from carts to checkouts halfway through a report, a change in the rate can reflect measurement rather than a change in shopping behavior.

42% of US online shoppers abandoned because they were just browsing or not ready to buy (Baymard Institute, 2025). A follow-up cannot assume that every one of those people wanted the purchase immediately.

Soft intent means the shopper is still considering the product or using the cart to collect information. Harder intent appears when someone reaches shipping or payment, returns to an unfinished purchase, or is an existing customer evaluating a familiar product.

Use those signals to prioritize which checkout to review first. A payment-stage exit may be a card failure, an unwanted charge or simply an interruption; inspect the checkout context before choosing the message.

Intent also does not establish calling permission. If you consider a voice follow-up, use the calling consent guide and keep the permission decision separate from your commercial assessment.

Excluding just browsing, extra costs are a reason for 40% of surveyed US shoppers, slow delivery for 20%, lack of trust with card details for 19%, and account creation for 18% (Baymard Institute, 2025). Show the payable total earlier, clarify arrival expectations, make business and payment information credible, and provide guest checkout.

Long or complicated checkout accounts for 17% and website errors or crashes for 17% (Baymard Institute, 2025). Remove unnecessary questions, preserve entered information after an error and test the complete checkout with the payment options you offer.

An unsatisfactory returns policy appears at 13%, inability to calculate the total up front at 12%, a declined card at 10%, and insufficient payment methods at 9% (Baymard Institute, 2025). Explain the actual returns terms, display costs clearly and provide useful payment-failure guidance instead of making the shopper start again.

These responses should guide investigation rather than be added into a prediction. The reduce abandoned carts guide translates the reasons into checkout fixes and a follow-up plan.

A recoverable checkout needs a remaining reason to buy, a way to reach the shopper appropriately, and a purchase your store can still fulfill. Product availability, delivery requirements and contribution margin all matter before you pay for another contact.

A product question or interruption may be resolved with useful information and a checkout link. A customer who cannot accept the delivery time or does not want the item may not be recoverable without changing the underlying offer.

Start with email where an address was supplied, and reserve SMS for opted-in shoppers. Calls can make sense for higher-intent checkouts when the expected additional margin covers an answered conversation, not because every cart above an arbitrary dollar amount should receive a call.

Never report all unfinished cart value as recoverable revenue. Some carts represent browsing, some contain unavailable products, and some would complete without intervention; recovery measurement should distinguish attributed purchases from the additional orders the follow-up actually caused.

Keep checkout starts, completed orders and unfinished checkouts as separate measures. Record the reason when a customer explains it, without treating silence as a particular objection.

Check that a later purchase closes the abandoned checkout in your operational process. If separate tools keep sending reminders after an order, shoppers receive outdated requests and your team loses a clear view of what is still unfinished.

Review returns, incentives and fulfillment costs alongside recovered revenue. A sale can be attributed to recovery but contribute little margin, so the commercial result is not established by the checkout total alone.

Use a stable reporting period and a consistent definition of a completed purchase. This makes checkout repairs, message changes and acquisition changes easier to distinguish instead of combining them into a single unexplained rate.
