Cart Abandonment Rate

Quick Definition

The percentage of online shoppers who add items to their cart but leave without completing the purchase.

What is Cart Abandonment Rate?

Cart abandonment rate is the percentage of shoppers who add items to their cart but leave without completing the purchase. It's one of the biggest revenue leaks in ecommerce.

The average cart abandonment rate is around 70%, meaning 7 out of 10 shoppers who add something to their cart don't buy. That's an enormous opportunity for recovery.

Why Cart Abandonment Happens

• Unexpected shipping costs
• Complicated checkout process
• Required account creation
• Security concerns
• Comparison shopping
• Distraction or decision fatigue
• Price shock at checkout
• Limited payment options

Reducing Cart Abandonment

• Show shipping costs early
• Simplify checkout to fewer steps
• Offer guest checkout
• Display security badges
• Send abandonment emails (recover 5-15%)
• Add exit-intent popups
• Offer multiple payment methods including buy-now-pay-later

Cart Abandonment Recovery

Abandoned cart email sequences can recover 5-15% of abandoned carts. These are high-intent prospects who just need a nudge. Send the first email within an hour of abandonment.

How to Calculate Cart Abandonment Rate Step by Step

Step 1: Pull cart and checkout data from your analytics.

• Carts created (sessions with add-to-cart): 3,200
• Completed purchases: 850

Step 2: Calculate.

• Abandoned carts = 3,200 - 850 = 2,350
• Abandonment Rate = 2,350 ÷ 3,200 = 73.4%

Nearly 3 out of 4 shoppers who add items to cart leave without purchasing. Industry average is 70%, so this is typical but improvable.

Step 3: Calculate the revenue opportunity. If the average abandoned cart value is $72:

• Lost revenue potential: 2,350 × $72 = $169,200
• At 10% recovery rate from emails: $16,920 recoverable revenue/month

Step 4: Identify where in checkout they drop off. Cart page → shipping info (85% proceed) → payment (70% proceed) → confirmation (95% proceed). The biggest drop is at payment — investigate: unexpected costs? Complex form? Limited payment options?

Common mistakes founders make:

• Panicking over 70% abandonment (it's normal — many carts are "window shopping")
• Not implementing abandoned cart email recovery (the single highest-ROI fix)
• Comparing to other industries (physical products have different benchmarks than digital)
• Not separating "abandoned cart" from "abandoned checkout" (different stages, different fixes)

Formula

Cart Abandonment Rate = (Abandoned Carts ÷ Total Carts Created) × 100

Or: 1 - (Completed Purchases ÷ Carts Created)

Example

Checkout funnel:

• Carts created: 10,000
• Checkouts completed: 3,000
• Carts abandoned: 7,000

Cart Abandonment Rate = 7,000 ÷ 10,000 = 70%

If your AOV is $80, that's $560,000 in abandoned carts. Even recovering 10% through email sequences means $56,000 in recaptured revenue.
