How Do You Calculate Cart Abandonment Rate?
Divide the number of completed purchases by the number of shopping carts created, subtract from 1, and multiply by 100.

Mobile abandonment typically runs 10 to 15 percentage points higher than desktop, which means a blended rate can hide a serious mobile problem.
