The 70% Problem: What a Decade of Research Found About the Cart Abandonment Rate
The average cart abandonment rate sits near 70 percent, and the most-cited body of research on why treats it as a solvable engineering problem rather than a persuasion failure. Aggregating fifty separate abandonment studies, the Baymard Institute puts the mean rate at roughly 70.22 percent; its own reason survey finds that unexpected costs revealed late in checkout (shipping, tax, and fees) are named by about 39 percent of abandoners, and being forced to create an account by about 24 percent. Read together, those two findings reframe the problem. The dominant causes of a high cart abandonment rate are not that the price is too high or the copy too weak. They are that the true total was disclosed too late and the funnel demanded too much before it let the buyer pay. That makes checkout a disclosure-and-sequencing problem, and disclosure-and-sequencing problems are diagnosable, prioritizable, and fixable in ways that a redesign on a hunch is not.
The 70 percent figure is real, but it is not one number
The headline statistic that circulates in conversion writing is a genuine aggregate, not a marketing invention. The Baymard Institute maintains an ongoing meta-analysis that pools fifty independently conducted cart-abandonment studies; the mean across that corpus is approximately 70.22 percent, meaning that of every ten shoppers who add an item and begin a purchase, roughly seven leave before completing it.
Two cautions belong next to that number before it is used. First, an average pooled across fifty studies with different populations, devices, and definitions is a central tendency, not a benchmark any single store should expect to match. A business with a returning, high-intent audience will sit well below it; a store driven by cold discovery traffic may sit above. Second, the figure conflates shoppers who never intended to buy in this session, the price-comparers and the list-savers, with shoppers who intended to buy and were stopped by the funnel itself. The research that matters is not the aggregate rate but the second group, because only that group is recoverable through better design.
What the checkout abandonment reasons actually are
The reframe comes from the reason taxonomy, not the rate. When Baymard surveys shoppers who abandoned a purchase they intended to make, the causes cluster, and they cluster away from price. The single most-cited reason is that extra costs, shipping, tax, and fees, appeared too high or too late at checkout, named by roughly 39 percent of respondents. The next structural cause is that the site required the shopper to create an account before buying, named by roughly 24 percent.
The precise wording of the leading reason matters. It is not "the price was too high." It is that the total was unexpected, disclosed after the shopper had already committed attention and effort. That is a statement about sequencing and honesty, not about willingness to pay. A shopper who would have paid the full amount had it been shown on the product page abandons when the same amount is revealed on the final screen, because the late reveal reads as a bait, and because it forces a re-decision at the moment of highest friction.
Why this is a disclosure problem, not a persuasion problem
The two dominant reasons share a structure. Undisclosed cost is a failure to state the truth early. Forced account creation is a demand for commitment before value has been exchanged. Neither is solved by more persuasive copy, a stronger guarantee, or a manufactured sense of urgency. They are solved by telling the buyer the whole price sooner and by removing the gate that stands between an intent-to-buy and a completed payment.
This is why the evidence quietly argues against the reflex most stores reach for first. Swapping a button color, adding a countdown timer, or rewriting a headline addresses persuasion. The data says the larger, more reliable losses are mechanical: a cost surprise and a mandatory account. Fixing the mechanical causes does not require guessing at a buyer's psychology; it requires auditing the funnel against what the research already names.
Checkout optimization is mostly the removal of steps
Baymard's second research asset, its Checkout Usability program, gives the constructive half of the picture. Built on more than 300,000 hours of large-scale usability testing since 2011, the program's central quantitative finding is that the average large ecommerce site can gain roughly a 35.26 percent increase in conversion rate from checkout-usability improvements alone, before a single change to traffic, price, or product.
That gain is a corpus-level estimate from one research organization, not a promise for any individual store, and it should be read as directional evidence that the ceiling on checkout improvement is high, not as a figure to forecast against. What gives it credibility is the mechanism the same program identifies: most of the recoverable loss traces to funnels that ask for far more than the transaction requires. Baymard finds that a well-designed checkout can be built from as few as 12 to 14 form elements, of which only 7 to 8 are true input fields, against the 20-plus elements typical on sites that have never been audited. Checkout optimization, in this evidence, is less about adding conviction and more about deleting steps.
How to reduce cart abandonment: sequence and disclose
If the leading causes are late cost and forced accounts, the highest-impact corrections follow directly from the taxonomy rather than from tactics. To reduce cart abandonment in a way the research supports, the moves are structural.
- Disclose the full landed cost early. Show shipping, tax, and fees on the product or cart page, or make them estimable before the final step, so the total the buyer commits to is the total they see at payment. This directly addresses the roughly 39 percent who abandon over unexpected cost.
- Offer a genuine guest checkout. Let a first-time buyer pay without creating an account, and offer account creation after the purchase, not before it. This addresses the roughly 24 percent who abandon over forced registration.
- Cut the form to the fields the transaction needs. Move from a 20-plus-element checkout toward the 12-to-14-element shape the usability corpus describes, removing optional fields and inferring what can be inferred.
- Reduce the mobile penalty. A checkout that is longer or more hostile on a phone abandons more, because that is where a growing share of the traffic decides. Parity between mobile and desktop friction is part of the fix, not an afterthought.
Checkout usability is now a compliance surface too
The disclosure finding has acquired a second dimension since Baymard first quantified it. In its 2022 staff report "Bringing Dark Patterns to Light," the Federal Trade Commission named buried or hidden fees, sometimes called junk fees, as one of four recurring patterns it treats as potentially actionable under Section 5 of the FTC Act. The tactic the research identifies as the top abandonment cause is the same tactic a regulator has flagged as a legal exposure.
The practical consequence is that early, honest cost disclosure is no longer only a conversion tactic; it is the low-risk position on a live compliance question. A store that reveals the full price early both recovers the largest named source of abandonment and stays clear of the pattern the FTC has singled out. Honest sequencing and defensible design point in the same direction here, which is rarely the case and worth stating plainly.
Reading the evidence carefully
The Baymard figures are the strongest public dataset on this question, and they still deserve careful handling. Baymard is a commercially interested party: it sells checkout research and auditing, so its point estimates should be treated as directional rather than as universal constants. The 70.22 percent aggregate pools studies with differing methods. The 35.26 percent conversion-gain figure is an average across the sites in its corpus, not a lift any specific site is guaranteed. The reason percentages come from Baymard's own survey instrument, with the sampling and question wording that implies.
None of that undermines the core claim, because the core claim does not depend on any single decimal. Across independent restatements, the direction is stable: abandonment is high, and the largest recoverable share of it is structural friction, cost surprise, forced accounts, and excess form length, rather than price or persuasion. The right way to use this research is as a diagnostic lens that tells you where to look on your own funnel, followed by measurement on your own store, not as a set of numbers to quote as if they were your results.
From a statistic to a diagnosis
The gap between the research and a decision is specificity. Knowing that the average cart abandonment rate is near 70 percent, and that cost surprise and forced accounts lead the reasons, tells you what to suspect. It does not tell you which of those causes is active on your store, how much each is costing, or which one to fix first. That requires walking your real purchase path, on the devices your buyers actually use, and locating where intent-to-buy turns into abandonment.
This is the difference between a benchmark and a diagnosis. A benchmark is a number you compare yourself to. A diagnosis is a ranked map of the specific leaks on your specific funnel, ordered by revenue at risk against effort to fix, with the reasoning behind each priority. The research in this article is the map legend. The territory is your checkout, and the only way to read it is to measure it.

Glossary
- Cart abandonment rate
- The share of shopping sessions that add an item and begin a purchase but leave before completing it. The documented average across pooled studies is near 70 percent.
- Checkout usability
- The measurable ease with which a shopper can complete a purchase, studied through large-scale task-based usability testing. Poor usability, not price, drives most recoverable abandonment.
- Forced account creation
- Requiring a shopper to register before they can pay. It is the second most-cited abandonment reason and is removed by offering a genuine guest checkout.
- Junk fees
- Mandatory costs disclosed late in checkout rather than up front. Named as the top abandonment reason and flagged by the FTC as a potentially actionable dark pattern.
- Disclosure sequencing
- The order in which a funnel reveals price and asks for commitment. Honest early disclosure of the full total is the highest-impact correction the research supports.
Straight answers
Frequently asked questions
What is a normal cart abandonment rate?
The most-cited public figure is an average of roughly 70.22 percent, aggregated by the Baymard Institute across fifty separate studies. It is a central tendency, not a target: a returning high-intent audience sits well below it, and cold discovery traffic can sit above it. Your own rate is only meaningful against your own funnel, not against the pooled average.
Why do most shoppers abandon their carts?
The research does not point to price. The single most-cited reason, named by about 39 percent of shoppers, is unexpected extra costs (shipping, tax, and fees) revealed too late in checkout. The second, at about 24 percent, is being forced to create an account before buying. Both are disclosure and sequencing failures, not persuasion failures.
How do I reduce cart abandonment without discounting?
Address the named structural causes rather than the price. Disclose the full landed cost early so there is no surprise at payment, offer a real guest checkout so first-time buyers can pay without registering, and cut the checkout form toward the 12-to-14-element shape the usability research describes. These target the mechanics that the evidence says drive most recoverable loss.
Is checkout optimization worth it for a small business?
The upside ceiling is high, but it should be measured, not assumed. Baymard reports the average large site can gain roughly 35.26 percent in conversion from checkout-usability fixes alone, which is a directional corpus average rather than a guarantee for any one store. The right approach is to diagnose your own funnel first, find the specific leaks, and fix the ones that carry the most revenue.
Are hidden fees a legal risk as well as a conversion problem?
They can be. The FTC named buried or hidden fees as one of four recurring dark-pattern tactics it treats as potentially actionable under Section 5 of the FTC Act in its 2022 staff report. Disclosing the full price early both recovers the largest source of abandonment and stays clear of the pattern the regulator has flagged.
