Measure the share of created carts that never complete checkout, where lower is better.
The abandonment rate is the share of carts created that carts abandoned represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where lower is better.
