The largest drop is between shipping to payment, losing 330 people. Shipping-cost shock is the most common cause of a drop at the shipping step, and it is fixable by showing the cost earlier rather than by lowering it.

How the Checkout Completion Rate Calculator works

Shipping-cost shock is the most common cause of a drop at the shipping step, and it is fixed by showing the cost earlier rather than by lowering it. Knowing which step loses the most people is what turns checkout work from guesswork into a queue.

Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.

Frequently asked questions

What is a good checkout completion rate?

Commonly 55% to 75% of started checkouts, with wide variation. The step-level breakdown is far more useful than the overall figure.

Where do most people drop out?

Usually at the shipping step, when total cost becomes visible for the first time. Payment step drops are more often technical — declined cards, failed validation, unsupported methods.

How do I reduce shipping-step drop-off?

Show shipping cost on the product page or in the cart. The people who leave were going to leave; showing them earlier means they do not consume a checkout slot and a support ticket.

What causes payment step failures?

Declined cards, 3D Secure friction, and missing local payment methods. Adding wallets and the payment methods your customers actually use addresses most of it.
