Cart Abandonment Rate Calculator

Cart abandonment rate measures the percentage of shoppers who add items to their cart but leave without completing the purchase. Calculate it by dividing abandoned carts by total carts initiated, then multiply by 100.

Baymard Institute's average of 50 studies is 70.22%, and Dynamic Yield's panel of 400+ brands measured 77.38% over the 12 months through September 2026. By category, Dynamic Yield puts pet care lowest at around 50% and beauty and personal care highest at around 80%. Mobile runs about 10 percentage points above desktop (79.53% against 69.56%). For the full breakdown, see our cart abandonment statistics.

In Baymard's 2026 survey of US online shoppers, the most common reason was just browsing or not being ready to buy (42%). Among fixable reasons, extra costs such as shipping, tax and fees led at 40%, followed by slow delivery (20%), not trusting the site with card details (19%) and being made to create an account (18%). Exit-intent surveys can help identify your specific friction points.

Show shipping costs early, offer guest checkout, simplify forms to essential fields only, display trust badges, and use exit-intent popups with incentives. In Klaviyo's October 2026 benchmark of more than 110,000 customers, abandoned cart emails averaged $6.77 in revenue per recipient, the highest of any Klaviyo flow.

Neither Shopify nor WooCommerce reports a cart abandonment rate directly. On Shopify, switch the Conversion rate breakdown report to the closed funnel (Open Funnel toggle off) and take 1 minus completed checkouts divided by sessions with cart additions. For checkout abandonment, use 100% minus Shopify's Checkout conversion rate. WooCommerce core Analytics has no cart or checkout report, so use a Google Analytics 4 funnel from add_to_cart to purchase (it counts users, not carts, so treat it as a proxy) or an extension that records carts.

Yes, include all visitors who initiated a cart, not just those who reached checkout. This gives you the true abandonment rate across the entire purchase funnel and shows where users drop off.

Monitor weekly trends but analyze monthly for actionable insights. Seasons and sales events move the rate for reasons unrelated to your checkout: in Dynamic Yield's latest data, December ran about five points below the rest of the year. Compare a month with the same month a year earlier.
