Cart Abandonment vs Checkout Abandonment: What's the Difference?

Cart abandonment occurs when a shopper adds an item to their cart but leaves the site without ever starting the checkout process - the drop-off happens at the browsing and consideration stage, before any purchase details are entered.

Checkout abandonment occurs when a shopper has already started checkout - sometimes entering shipping or payment information - but leaves before completing the purchase, meaning the drop-off happens further along, inside the actual payment flow.

The difference matters because a combined abandonment number blends together two problems with completely different causes and fixes. Cart abandonment tends to have a larger total volume, since it captures anyone who showed even passing purchase intent, and its causes are usually upstream of pricing and product fit - unexpected costs discovered on the next screen, comparison shopping, or simply browsing without buying intent yet. Checkout abandonment represents a smaller but higher-intent group, since these are shoppers who had already committed enough to begin entering information, which is why checkout abandonment recovery flows typically convert at a higher rate per recipient than cart abandonment flows do. Diagnosing cart abandonment points toward fixing earlier-stage friction - shipping cost transparency, product page trust signals - while diagnosing checkout abandonment specifically points toward the payment flow itself: too many required fields, missing payment methods, or an unexpectedly long process once someone has already decided to buy.
