How Do I Calculate Cart Abandonment Rate?

Cart abandonment rate = (1 − completed purchases ÷ carts created) × 100

Say 1,000 shoppers created a cart and 300 of them bought:

1. 300 ÷ 1,000 = 0.3
2. 1 − 0.3 = 0.7
3. 0.7 × 100 = 70%

So 70% of carts were abandoned. Use the same date range and the same definition of a created cart each time you measure, or the trend won't tell you anything. Most store platforms report both numbers in their analytics.

To win some of those shoppers back, show a coupon when they go to leave. Build it as a Capture with the On Exit trigger, or start from our Shopping Cart Abandon template. Then measure again over the same length of time to see whether the rate moved.
