How the Cart Abandonment Calculator Works
What is Cart Abandonment?
Cart abandonment occurs when shoppers add products to their online shopping cart but leave the website without completing the purchase. It's calculated as: Cart Abandonment Rate = (Abandoned Carts ÷ Total Carts) × 100%. For example, if 1,000 carts were created and 300 resulted in purchases, you had 700 abandoned carts and a 70% abandonment rate. The inverse— completion rate—would be 30%. Cart abandonment is one of the most critical eCommerce metrics because it directly impacts revenue and reveals friction in the checkout process.
Why Cart Abandonment Matters for eCommerce
Cart abandonment represents massive lost revenue opportunity for online stores. With average abandonment rates around 70%, most eCommerce businesses lose more than two-thirds of potential sales at the final step. Understanding abandonment matters because: (1) It reveals checkout friction—high abandonment signals problems with user experience, trust, or pricing transparency. (2) It quantifies recoverable revenue— many abandoned carts can be recovered through email campaigns, retargeting, or checkout optimization. (3) It benchmarks performance—comparing your rate to industry standards identifies competitive gaps. (4) It prioritizes optimization— reducing abandonment by even 5-10% can generate significant additional revenue without increasing traffic. (5) It improves customer experience—addressing abandonment drivers makes shopping easier for all customers, not just recoveries.

Example Scenario
Inputs:
- Total carts: 1,000
- Completed purchases: 300
- Average order value: $75
Results:
- Abandoned carts: 700
- Abandonment rate: 70%
- Completion rate: 30%
- Estimated lost revenue: $52,500
This store has average abandonment (70%), with 700 out of 1,000 carts not converting to purchases. At $75 average order value, this represents $52,500 in at-risk monthly revenue. Implementing abandoned cart emails and checkout optimization to recover just 15% of abandoners (105 carts) would generate an additional $7,875 in monthly revenue—$94,500 annually.
