Cart Abandonment Rate Calculator

Cart abandonment rate is the share of shoppers who add at least one item to the cart but never complete an order. It captures intent that formed but did not convert — a wider net than checkout abandonment, which only counts shoppers who began the checkout itself.

Because the signal of intent is real (they built a cart), the gap between carts and orders is recoverable demand. Closing part of it is usually cheaper than acquiring fresh visits.

Here, lower is better — the verdict is read on the cart-to-order completion behind the number:

Low — abandonment well above the median; the cart-to-checkout path is leaking intent. Average — near the median; reminders and friction fixes pay off. Strong — abandonment at or below the median; the constraint has moved elsewhere.

Cart abandonment is the broad measure — everyone who added an item but did not buy. Checkout abandonment is the narrower, higher-intent slice who actually started checkout. Read them together: a high cart rate but a healthy checkout rate points to pre-checkout friction; the reverse points to friction at payment. The related tools cover both.

The reliable levers reduce surprise and friction and re-engage intent: show total cost (including shipping) early, persist carts across devices and sessions, send timely and well-targeted cart reminders, streamline the path from cart to checkout, and reassure on returns and delivery. Model each as a scenario above to see the revenue it recovers.

Not entirely. Many shoppers use the cart as a shortlist or price-check, so some abandonment is structural rather than friction. That is why the benchmark sits high — the goal is to beat your category median and recover the addressable share, not to chase zero. Pair this with revenue per visitor to keep the focus on recovered revenue, not just a lower percentage.
