About This Tool

Estimate the percentage of shopping carts that were created but did not result in completed purchases. This metric can help ecommerce teams investigate checkout friction, payment problems and other conversion barriers.

How to Use It

Enter the number of carts or checkout sessions created and the number of completed purchases for the same reporting period. The calculator returns the corresponding abandonment rate.

How the Calculation or Check Works

A common calculation is (carts created − completed purchases) ÷ carts created × 100. The exact definition should match the analytics platform and reporting events used by your store.

Practical Example

If 1,000 carts are created and 250 purchases are completed, 750 carts did not convert, producing a 75% abandonment rate under this definition.

Frequently Asked Questions

Is cart abandonment the same as checkout abandonment? Not necessarily. Different analytics systems define cart and checkout events differently.

Why should I compare periods consistently? Changes in tracking definitions, traffic mix or attribution can make percentages misleading.

Does a high abandonment rate identify one specific problem? No. It is a signal that should be investigated alongside device, payment, shipping and funnel data.
