Why customers abandon carts (and how to fix each reason)

Most cart abandonment isn’t random — it traces to a handful of specific frustrations. Here are the leading reasons (from Baymard Institute research) and the fix for each.

1. Unexpected extra costs — 39%

Shipping, tax and fees that appear only at checkout feel like a bait-and-switch. Fix: show costs on the product and cart pages, or use a free-shipping threshold above your average order value.

2. Slow or unclear delivery — 21%

“When will it arrive?” with no answer loses the sale. Fix: show a delivery estimate on the product page and offer one faster paid option.

3. Being forced to create an account — 19%

Sign-up walls add friction before the sale. Fix: turn on guest checkout — usually a single setting.

4. A long or complicated checkout — 18%

Every extra field loses people. Fix: cut optional fields, add address autocomplete, and enable express pay.

5. Not trusting the site with card details — 17%

If checkout doesn’t feel safe, people don’t enter a card. Fix: add recognisable payment logos, a security badge, and visible reviews.

The unavoidable ones

Around 43% of shoppers abandon because they were “just browsing” — comparing prices or saving for later. You won’t convert all of those, and that’s fine. Focus your energy on the fixable frictions above.
