Step-by-Step Examples
Example 1
Typical Store
12,000 carts, 4,800 checkouts, 2,160 purchases, AOV 78, 12% recovery, 42% margin.
- Cart abandonment = 1 − (2,160 / 12,000) = 82.0%
- Cart to checkout drop-off = 60.0%
- Checkout abandonment = 1 − (2,160/4,800) = 55.0%
- Abandoned = 9,840 carts worth 767,520
- At 12% recovery: 1,181 orders, 92,102 gross, 38,683 contribution
✓ 82.0% abandonment, 38,683 recoverable contribution
Example 2
Checkout Problem
8,000 carts, 6,400 checkouts, 1,920 purchases.
- Cart abandonment = 76.0%
- Cart to checkout drop-off only 20.0%
- Checkout abandonment = 70.0%
- People reach checkout then leave — a friction or cost-disclosure problem
✓ 70.0% checkout abandonment
Example 3
Browsing Problem
20,000 carts, 3,000 checkouts, 2,100 purchases.
- Cart abandonment = 89.5%
- Cart to checkout drop-off = 85.0%
- Checkout abandonment only 30.0%
- Carts are being used as wishlists — checkout itself performs well
✓ 85.0% lost before checkout
Real-World Applications
Recoverable Revenue
Abandoned cart email and retargeting programmes routinely recover a meaningful share of otherwise lost orders.
Stage Diagnosis
Separating cart-to-checkout from checkout abandonment shows whether the problem is intent or friction.
Shipping Transparency
Unexpected shipping cost at checkout is consistently the most cited abandonment reason in industry surveys.
Benchmark Context
Ecommerce cart abandonment commonly runs around 70%, so a high rate is normal rather than alarming in itself.
Common Mistakes to Avoid
⚠️
Treating all abandonment as recoverable
Many carts are used as wishlists or price comparisons with no purchase intent. Recovery programmes address a subset, not the whole figure.
⚠️
Not separating cart from checkout abandonment
They have entirely different causes. Cart abandonment reflects intent; checkout abandonment reflects friction, cost surprises, or payment problems.
⚠️
Valuing abandoned carts at full revenue
Recovered orders should be valued at contribution margin, not gross revenue, and only the realistically recoverable share counts.
Frequently Asked Questions
What is a normal cart abandonment rate? ▾
Industry averages commonly sit around 70%, with mobile typically higher than desktop. Rates above 80% are common in some categories.
What causes cart abandonment? ▾
Unexpected shipping or fees at checkout, forced account creation, complex checkout flows, limited payment options, and simple comparison shopping.
How much can recovery emails recover? ▾
Well-executed abandoned cart email sequences commonly recover in the range of 5 to 15% of abandoned carts, varying by category and timing.
Should I distinguish cart from checkout abandonment? ▾
Yes. They point to entirely different fixes — cart abandonment suggests intent or pricing issues, checkout abandonment suggests friction.
How should recovered revenue be valued? ▾
At contribution margin rather than gross revenue, and net of any discount offered to incentivise the recovery.
