Cart Abandonment Rate Calculator
Measure the share of created carts that never complete checkout, where lower is better.
About Cart Abandonment Rate Calculator
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.
