Understanding cart abandonment

The average cart abandonment rate across eCommerce is around 70%. That means 7 out of 10 shoppers who add items to their cart leave without buying. Even reducing abandonment by 5–10 percentage points can mean a massive revenue increase.

Formula: Cart Abandonment Rate = ((Carts Created − Completed Purchases) / Carts Created) × 100

Top reasons for cart abandonment

Unexpected costs

Shipping fees, taxes, and handling charges shown at checkout are the #1 reason shoppers abandon. Show total cost as early as possible.

Forced account creation

Requiring signup before purchase kills conversions. Always offer guest checkout – you can ask for account creation post-purchase.

Complex checkout flow

Every extra step in checkout loses ~10% of shoppers. The best checkouts are 1–2 steps max with progress indicators.
