What is Cart Abandonment Rate?
Cart abandonment rate measures the percentage of shoppers who add items to their online cart but leave without completing the purchase. It's one of the most critical e-commerce metrics because it reveals how much potential revenue slips away at the final step. High abandonment often signals checkout friction, unexpected costs, or trust issues.
Formula
Cart Abandonment Rate = (1 - (Completed Purchases ÷ Carts Created)) × 100
Alternative formula:
Cart Abandonment Rate = (Abandoned Carts ÷ Carts Created) × 100
Understanding Results
| Abandonment Rate | Interpretation |
|---|---|
| Below 50% | Excellent—highly optimized checkout |
| 50-60% | Good—better than average |
| 60-70% | Average—room for improvement |
| 70-80% | Below average—needs attention |
| Above 80% | Critical—immediate optimization required |
Industry average hovers around 70%, according to Baymard Institute research.
When to Calculate
Track cart abandonment monthly as a baseline. Also calculate after redesigning checkout flow, changing shipping rates or payment options, running promotions or sales, and when comparing mobile vs. desktop performance.
How to Calculate with Example
Scenario: Online retailer analyzing monthly performance
Inputs:
- Shopping carts created: 2,000
- Completed purchases: 600
Calculation: Cart Abandonment Rate = (1 - (600 ÷ 2,000)) × 100 Cart Abandonment Rate = (1 - 0.30) × 100 = 70%
This means 70% of shoppers who added items to their cart left without buying—1,400 potential orders lost.
How to Improve
- Show all costs upfront — Unexpected shipping and fees cause 48% of abandonments
- Offer guest checkout — Don't force account creation before purchase
- Simplify the checkout — Reduce form fields and steps to minimum
- Add multiple payment options — Include PayPal, Apple Pay, buy-now-pay-later
- Send recovery emails — Abandoned cart emails recover 5-11% of lost sales
