What is checkout abandonment rate?

Checkout abandonment rate measures the percentage of visitors who begin checkout but do not complete payment. If 8,000 visitors started checkout and only 5,200 completed a purchase, the checkout abandonment rate is 35%.

This metric differs from cart abandonment rate in an important way. Cart abandonment captures all visitors who added items but did not buy, including those who were casually browsing. Checkout abandonment captures only those who took the deliberate step of entering the checkout flow, making it a more precise measure of friction at the final stage.

Visitors who abandon at checkout have demonstrated the strongest purchase intent possible without completing the transaction. The causes are typically specific and fixable: unexpected costs revealed at checkout, required account creation, limited payment options, a long or confusing form, payment failures, or security concerns. Each of these can be diagnosed with step-level analytics and addressed with targeted improvements.

Implement step-level tracking within your checkout flow. Knowing that 25% of abandonment happens at the shipping information step versus the payment step leads to entirely different optimisation priorities.

How to reduce checkout abandonment

  1. 1

    Offer guest checkout

    Forcing account creation before purchase is one of the top causes of checkout abandonment. Allow guest checkout and offer account creation after the purchase is complete, when the customer has already committed.

  2. 2

    Support digital wallets and express payment

    Apple Pay, Google Pay, and Shop Pay reduce the checkout form to a single authentication step. For mobile shoppers especially, digital wallets eliminate the friction of typing card numbers and addresses on a small screen.

  3. 3

    Display the total cost upfront

    Shipping costs, taxes, and fees revealed at the final checkout step are the leading cause of abandonment. Show estimated totals as early as possible so there are no surprises at the moment of payment.

  4. 4

    Reduce form fields to the minimum required

    Every additional field increases cognitive load and abandonment risk. Use address auto-complete, pre-fill data for returning customers, and remove optional fields unless they serve a critical purpose.

  5. 5

    Add trust and security signals at checkout

    Display security badges, SSL indicators, payment provider logos, and a clear return policy directly on the checkout page. Customers need reassurance at the point of entering payment details.

Checkout Conversion Rate = (Completed Purchases / Checkout Starts) x 100

Checkout conversion rate measures the percentage of users who begin the checkout process and successfully complete their purchase. It isolates the final stage of the buying funnel, from the moment a shopper initiates checkout to the order confirmation page. This metric is critical for e-commerce businesses because the checkout is where purchase intent is highest, and any friction at this stage directly destroys revenue that was nearly captured.
