What Is Cart Abandonment Rate?

Cart abandonment rate measures the percentage of shoppers who add items to their cart but leave without completing a purchase. Learn how to calculate and reduce it.

Key Takeaways

  • Cart abandonment rate is calculated by dividing incomplete transactions by total carts created, multiplied by 100.
  • The global average cart abandonment rate is approximately 70%, meaning most potential sales are lost at checkout.
  • The top causes are unexpected costs, complicated checkout processes, and mandatory account creation.

How to calculate it

Cart abandonment rate equals the number of completed purchases divided by the number of shopping carts created, subtracted from one, then multiplied by 100. If 1,000 shoppers add items to their cart and 300 complete a purchase, your abandonment rate is 70%. This metric directly quantifies revenue leakage at the final stage of the buying journey. Even small improvements in abandonment rate can significantly impact total revenue.

Why shoppers abandon carts

Research consistently identifies the same causes. Unexpected shipping costs are the leading factor — customers feel deceived when costs appear only at checkout. Complicated checkout requiring too many steps or mandatory account creation drives exits. Slow page load times, limited payment options, and security concerns also contribute. In African markets, lack of familiar payment methods like mobile money and cash-on-delivery options disproportionately increases abandonment.

Reducing abandonment

Display total costs including shipping early in the browsing experience. Offer guest checkout. Reduce checkout to three steps or fewer. Provide multiple payment options — in African markets, integrate M-Pesa, Paystack, and card payments alongside cash-on-delivery. Send abandoned cart recovery emails within one hour. Offer incentives like free shipping thresholds. Nigerian ecommerce platforms that added Paystack express checkout reported abandonment reductions of 15 to 25 percentage points.

Benchmarking your rate

Average abandonment rates vary by industry: travel (82%), fashion (68%), electronics (74%), and grocery (51%). Mobile abandonment rates are typically 10 to 15 percentage points higher than desktop. Compare your rate against your specific industry and device breakdown rather than a single global average. Track the metric weekly, segmented by traffic source and device type, to identify which customer segments need the most checkout optimization.
