Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| 700 abandoned out of 1,000 carts created | 70% abandonment rate | Abandonment rate = (700 ÷ 1,000) × 100 = 70%. |
| 450 abandoned out of 600 carts created | 75% abandonment rate | Abandonment rate = (450 ÷ 600) × 100 = 75%. |
The Cart Abandonment Formula
Abandonment rate = (carts abandoned / carts created) x 100, or equivalently, 100% minus your checkout completion rate. Estimated lost revenue can then be found by multiplying abandoned carts by your average order value, giving a rough sense of the revenue opportunity at stake.
Common Causes of Cart Abandonment
Frequently cited reasons include unexpected extra costs revealed at checkout (shipping, taxes, fees), a mandatory account creation requirement, a checkout process that's too long or complicated, and simple comparison shopping where the visitor never intended to complete the purchase on that visit.
