# Cart Abandonment

Cart abandonment is the share of shoppers who add items to a basket and leave without completing the purchase — around 70% across e-commerce by most studies — of which a meaningful part happens at the payment step: a forced account, a missing payment method, a clumsy authentication, a decline, a form that fails on a phone. Payments teams own that part, measure it as checkout abandonment, and recover it with guest checkout, wallets, local methods, frictionless authentication and retries.

**Also known as:** Checkout abandonment, Basket abandonment, Abandoned carts

## Key facts

- **Used at:** every e-commerce funnel analysis; the payments team's slice is the checkout-to-payment-success rate, the metric that PSPs, checkout vendors and orchestration platforms sell against
- **Binding:** no rule — but SCA in Europe made authentication abandonment a regulated cost, and the exemptions the answer
- **Typical figures:** overall cart abandonment 65–75% (Baymard's long-running average is about 70%); of shoppers who reach the payment page, 10–25% abandon; surveyed reasons include extra costs shown late, being forced to create an account, a long form, no trusted payment method, a declined card, and a checkout that fails on mobile
- **Typical payments levers:** guest checkout, saved cards and wallets (one tap instead of a form), local payment methods per market, 3DS 2 with exemptions and full data (frictionless rates up, challenge abandonment down), instant retry on soft declines, address autofill, a mobile-first form
- **Parties:** the merchant's product and payments teams, the PSP or checkout vendor, the issuers (whose challenges and declines are part of it), and the shopper who leaves

## How cart abandonment works in practice

Ten thousand shoppers add to basket. Seven thousand leave before checkout — browsing, comparing, distracted; not the payments team's problem. Three thousand start checkout. Four hundred leave at the account-creation wall; two hundred at a form that asks for a phone number and a company name; three hundred at a payment page that offers only cards in a market that pays by bank transfer; one hundred and fifty at a 3-D Secure challenge that redirected them to a page their bank's app never opened; one hundred at a decline the merchant did not retry. Eighteen hundred and fifty pay. The payments team's abandonment is 38% of those who started checkout, and every one of those reasons has a fix.

The fixes are known and cumulative. Guest checkout removes the wall. Wallets — Apple Pay, Google Pay, PayPal — turn a form into a tap. Local methods give each market what it uses. Authentication with full data and exemptions cuts challenges; in-app challenges cut the abandonment on those that remain. Retry logic and cascading recover declines that were not the customer's fault. A checkout tested on a three-year-old phone on a slow connection catches the rest. Each is worth points, and points on a large funnel are millions.

For a payments company the checkout conversion it delivers is the product; for a buyer of an e-commerce business, checkout abandonment against the category's norm is a line in commercial diligence.

## Example

A fashion retailer's checkout converts 62% of shoppers who start it. Its payments and product teams run a programme over two quarters: guest checkout (+5 points), Apple Pay and Google Pay (+4), local methods in three markets (+3 in those markets), 3DS 2 with full data and TRA exemptions (+3, as challenges fall from 40% to 15%), instant retry on soft declines (+1), address autofill and a mobile form rebuild (+2). Checkout conversion reaches 79%. On €50m of prior sales, the uplift is worth about €13m a year at the same traffic, for a programme that cost €400,000 and a PSP fee increase of 0.05%. The marketing team's budget for the same €13m of sales would have been €4m.

## Common mistakes

- Measuring cart abandonment as one number and never splitting the checkout step by cause.
- Forcing account creation before payment.
- A single payment method in markets that use others.
- Treating authentication abandonment as the regulator's fault when the data population and exemptions are the merchant's.
- Optimising checkout on the desktop the product team uses rather than the phones the customers do.
