What Is Shopping Cart Abandonment? A Straight Answer

Shopping cart abandonment is when a shopper adds items to an online cart but leaves before paying. It is measured as the share of created carts that never become orders. The documented average is 70.22% across 50 studies, so roughly 7 of every 10 carts are abandoned before checkout finishes.

That number has barely moved in a decade. The good news is that most of the lost orders trace back to a short list of fixable problems, and you can find which ones are hurting you without guessing.

How is the cart abandonment rate calculated?

Take the carts created in a period, subtract the ones that turned into completed purchases, and divide by the carts created. A store with 1,000 carts and 300 orders has a 70% abandonment rate.

The metric counts intent, not just browsing. A cart only exists once someone has chosen something and started toward buying it, which is what makes a 70% loss rate worth paying attention to. These are people who wanted the product enough to add it.

What is a good shopping cart abandonment rate?

Lower than your own last quarter is the only benchmark that matters, but context helps. Baymard's aggregate of 50 studies puts the average at 70.22%, so anything well below that is healthy.

No store reaches zero, and you should not aim for it. In Baymard's survey, 43% of shoppers who abandoned a cart said they were just browsing or not ready to buy. That share is mostly out of your hands. The reachable wins sit in the other group: people who tried to check out and ran into friction.

Why do people abandon their carts?

Among shoppers who abandoned for a reason other than browsing, Baymard found a clear ranking:

• Extra costs too high (shipping, tax, fees): 39%
• Delivery was too slow: 21%
• Did not trust the site with card details: 19%
• Site forced account creation: 19%
• Checkout was too long or complicated: 18%

The top cause has held first place for years. When shipping and fees only appear on the final step, the total jumps past what the shopper expected and they leave. The fix is usually nothing more than honesty earlier: show the full cost on the product or cart page, not after they have filled in an address.

Is cart abandonment the same as checkout abandonment?

No, though the terms get mixed up. Cart abandonment covers anyone who leaves after adding an item, including people who never start checkout. Checkout abandonment is the narrower slice: shoppers who began the checkout flow and quit partway through.

The distinction matters because the causes differ. Cart-stage drop-off often comes from price, indecision, or sticker shock at shipping. Checkout-stage drop-off points at the form itself: too many fields, a forced account, a card error, or a step that feels unsafe. If you only track one number, you cannot tell which problem you have. Reading the checkout abandonment rate separately tells you whether the leak is before or during payment.

How much does cart abandonment cost a store?

More than most owners assume, because the shoppers were already qualified. They picked a product and started to buy. Recovering even a few percentage points of a 70% loss rate is often the cheapest growth a store can find, since it converts demand you have already paid to attract instead of buying more traffic.

Work the math on your own numbers. If 39% of your reasoned abandonment is surprise costs, and a clear shipping line on the cart page recovers a slice of that, the gain compounds across every order for the rest of the year.

How do you reduce shopping cart abandonment?

The changes that move the needle most match the top reasons people leave:

• Show all costs early. Put shipping, tax, and fees on the cart page so nothing is a surprise at the end.
• Offer guest checkout. A forced account drove 19% of reasoned abandonment. Let people buy first and create an account after.
• Shorten the form. Baymard finds a guest checkout can run on as few as 6 to 8 form fields, far fewer than most sites ask for. Cut every field you do not truly need.
• Make trust visible. Familiar payment logos, a clear returns policy, and standard security cues address the 19% who hesitate over card safety.
• Test on a phone. Mobile checkouts abandon at higher rates than desktop, usually because small tap targets and long forms are harder on a small screen.

None of this requires a rebuild. Most abandonment fixes are edits to copy, field count, and where information appears.

How do you find what's driving abandonment on your own site?

Benchmarks tell you the average store loses 70% of carts. They do not tell you which step of your checkout is bleeding. For that you need to watch real attempts to buy.

The usual ways are slow: install analytics and wait for enough sessions, or recruit testers and schedule calls. CanaryUsers skips both. It sends a flock of lifelike AI users through your live checkout and reports exactly where they stall, from a confusing shipping line to a field that rejects valid input, each with a concrete fix. You do not need existing traffic or a recruiting budget. Run a free scan and see your funnel through a first-time buyer's eyes before the next shopper hits the same wall.
