How It Works

How to Calculate Cart Abandonment Rate

Formula

Abandonment Rate = ((Carts Created - Purchases Completed) / Carts Created) x 100

Cart abandonment is e-commerce's biggest revenue leak. The global average abandonment rate hovers around 70%, meaning seven out of ten shoppers who add items to their cart never buy. Each abandoned cart represents intent that was not converted. Recovering even a small fraction of abandoned carts through retargeting emails and checkout optimization can dramatically boost revenue.

Worked Example

10,000 shopping carts were created and 3,000 purchases were completed.

carts_created = 10000purchases_completed = 3000
  1. 01Abandoned Carts = 10,000 - 3,000 = 7,000
  2. 02Abandonment Rate = (7,000 / 10,000) x 100 = 70%
  3. 03Completion Rate = (3,000 / 10,000) x 100 = 30%
