Cart Abandonment Rate
The percentage of eligible initiated carts that do not result in a completed order within the selected reporting window.
Business question
How often are eligible initiated carts left without a completed order?
Formula
Cart abandonment rate = initiated eligible carts that did not result in a completed order ÷ eligible initiated carts × 100.
Calculation notes
Define cart identity, the reporting window, what counts as a completed order, and how recovered carts are linked to the original cart. State whether the cohort is based on cart initiation or order completion date.
Edge-case guidance
Document cross-device limitations, duplicate carts, guest and signed-in identity matching, partial payment attempts, stock changes, and carts that remain open beyond the reporting window.

Interpretation
Use the measure to identify friction between product selection and purchase completion. Read it with payment, shipping, pricing, stock, device, and customer-intent context.
Caution
A lower abandonment rate may reflect a narrower or more motivated audience rather than a better overall customer experience. Do not infer the reason for abandonment without supporting evidence.
Implementation recommendation
Agree on a cart identity and recovery window, then segment the trend by device, payment path, shipping option, product group, and stock status where the data supports it.
Target guidance
Set the first target from comparable historical performance for cart abandonment rate, then adjust it for the business model, strategy, capacity, seasonality, data quality, and customer commitments. Review the direction with the accountable owner and consider this trade-off: reducing abandonment through aggressive incentives may weaken margin or attract orders that are costly to fulfill.
