How It Works
Cart abandonment is the phenomenon where shoppers add items to their cart but leave without completing the purchase. The global average cart abandonment rate is approximately 70%, meaning 7 out of every 10 shoppers who express purchase intent do not buy. Recovering even a small percentage of these shoppers represents significant revenue with minimal incremental cost.
The Formula
Variables
- ATC Rate — Percentage of visitors who add at least one item to cart
- Abandonment Rate — Percentage of shoppers who add to cart but do not complete purchase
- ACV — Average value of abandoned carts
- Recovery Rate — Percentage of abandoned carts successfully converted through recovery tactics
Worked Example
Your store gets 10,000 visitors per month. 8% add to cart (800 carts), and 70% abandon (560 carts). At an average cart value of $85, you are losing $47,600 per month. If you implement abandoned cart emails with a 10% recovery rate, you would recover $4,760 per month or $57,120 per year — with software costs typically under $100/month.
Practical Tips
- A 3-email abandoned cart sequence outperforms a single email by 70% — send the first email within 1 hour, a second at 24 hours, and a third at 72 hours with a discount.
- The most common abandonment reasons are unexpected shipping costs, forced account creation, and a complicated checkout. Fix these before investing in recovery sequences.
- Exit-intent popups offering a small discount (5-10%) capture abandoners before they leave and typically convert at 3-7%.
- SMS abandoned cart messages have higher open rates than email (90%+ open rate) but should be used sparingly — get explicit opt-in.
- Retargeting ads on Facebook and Google can re-engage visitors who did not leave an email, typically at a CPM of $5-$15.
Frequently Asked Questions
What is the average cart abandonment rate?
The global average cart abandonment rate across industries is approximately 70-75%, according to Baymard Institute's research on over 40 published studies. Mobile cart abandonment is even higher at around 80-85%. If your rate is below 60%, you are performing above average.
What causes high cart abandonment?
The top reasons (per Baymard Institute): unexpected extra costs like shipping at checkout (48%), required account creation (24%), slow delivery (22%), site security concerns (18%), and complicated checkout (17%). Showing shipping costs early and offering guest checkout are the highest-impact fixes.
What is the best tool to recover abandoned carts?
Klaviyo, Omnisend, and Shopify's built-in abandoned checkout emails are the most popular options. For stores on Shopify, the built-in abandoned checkout email is free and easy to enable. Klaviyo offers more advanced segmentation and multi-step flows for higher recovery rates.
Should I always offer a discount in abandoned cart emails?
Not necessarily. Many shoppers abandon for non-price reasons and will return without a discount. Send the first email without a discount — just a reminder. Reserve the discount for the second or third follow-up to avoid training customers to abandon carts in expectation of a coupon.
How do I calculate add-to-cart rate?
Add-to-cart rate = sessions where a product is added to cart / total sessions × 100. In Google Analytics 4, this is tracked as an e-commerce event. Shopify Analytics shows it natively in the conversion funnel report. The average e-commerce add-to-cart rate is 6-10%.
