- Calculate the share of initiated shopping carts that do not convert.
- Use the result with the recorded inputs: Initiated carts, Completed purchases.
- Compare multiple scenarios before making a ecommerce decision.

How to interpret the result
Inspect device, channel, shipping surprise, errors, and measurement gaps before changing checkout.
Use the result as a decision aid rather than a standalone conclusion. Compare trends and scenarios using unchanged definitions.
Assumptions and limitations
