Cart Retention Rate measures the percentage of online shoppers who add items to their cart and return later to complete the purchase, even if they initially leave without buying. It’s a key eCommerce metric for understanding how well your business re-engages customers and recovers potentially lost sales.
How to Calculate Cart Retention Rate
The formula for Cart Retention Rate is:
Cart Retention Rate (%) = (Number of carts recovered / Number of abandoned carts) × 100
- Identify abandoned carts: Track users who added items to their cart but left without purchasing.
- Track recoveries: Measure how many of those users return and purchase within a set time frame.
- Calculate the percentage: Divide recovered carts by abandoned carts and multiply by 100.
- Use time windows: Often calculated over 7, 14, or 30 days for accuracy.
- Segment results: Compare retention across products, campaigns, and customer segments.
