What Is This Calculator?

Cart abandonment rate measures the percentage of online shoppers who add items to their cart but leave without purchasing. The global average is around 70%. Common reasons include unexpected shipping costs, required account creation, and complicated checkout processes.

How to Calculate

To calculate cart abandonment rate: 1) Count total shopping carts created. 2) Count completed purchases. 3) Subtract completions from carts. 4) Divide by total carts. 5) Multiply by 100. Formula: Abandonment Rate = (1 − Completed / Created) × 100.

Examples

Example: 1,000 carts created, 300 completed. Abandonment Rate = (1 − 300/1,000) × 100 = 70%. If AOV is $50, lost revenue = 700 × $50 = $35,000.
