Your bounce rate is lying: how inaccessible checkouts quietly cost £17 billion

Published 5 July 2026

The real cost of an inaccessible website is not a fine or a lawsuit. It is revenue you never see leaving. Disabled shoppers rarely complain when a checkout fights them. They just go, and your analytics log it as an ordinary bounce. The Click-Away Pound survey found that 69% of disabled online shoppers "click away" from sites they find hard to use, and that UK retailers lose an estimated £17.1 billion a year as a result (clickawaypound.com; AbilityNet).

If you run an online shop, that is the number to sit with. Not because a regulator is coming, but because the money already is going, and nothing in your dashboard tells you why.

What does an inaccessible website actually cost you?

Start with the headline figure. Across the UK, businesses lose an estimated £17.1 billion a year by failing to meet the online needs of disabled customers (AbilityNet). That is not a projection of possible penalties. It is spending that reached a competitor instead, quietly, order by order.

This is not a wobbling one-off statistic either. The earlier 2016 Click-Away Pound survey found that more than 4 million people abandoned retail sites they found difficult to use, taking roughly £11.75 billion in spending with them (clickawaypound.com). The 2019 figure is higher. The trend is going the wrong way for anyone who ignores it, which makes sense: more of retail moves online every year, so more of the friction moves online too.

Why your bounce rate hides all of this

Here is the trap. A bounce looks the same in your analytics whether a visitor lost interest or hit a wall they physically could not climb. A screen reader user who reaches a checkout field announced only as "edit text", with no label telling them what to type, does not send you an angry email. They abandon the cart. In your reports that session is indistinguishable from someone who wandered off to make a cup of tea.

So the cost is invisible by design. You cannot A/B test your way out of a problem your instrumentation cannot detect, and you will never see the drop-off attributed to its real cause. The only way to find it is to test the site the way these customers experience it, with a keyboard and a screen reader, rather than trusting a funnel chart that averages everyone together.

Is this really a large enough group to matter?

Yes, and it is not close. The World Health Organization estimates that about 1.3 billion people, roughly 16% of the world's population or one in six of us, live with a significant disability (WHO, 2023). That is not a rounding error at the edge of your market. It is a share of every market.

And this group spends. Widely-cited estimates put the global disability market, meaning people with disabilities together with their friends and families, at over $18 trillion in disposable income, with the UK "Purple Pound" (the spending power of disabled households) at around £274 billion (W3C WAI, Business Case for Digital Accessibility). Treat the exact totals as estimates rather than accountancy, but the order of magnitude is the point: this is a mainstream customer base, not a charitable afterthought. We dig into those numbers in more depth in 1 in 6 people, trillions in spending.

What actually makes a disabled shopper click away?

It is worth being concrete, because "accessibility" sounds abstract until you watch it break a sale. A landmark study of 100 blind screen reader users catalogued their most common frustrations on the web: confusing page layout and screen-reader feedback, conflicts between the screen reader and the web application, poorly designed or unlabelled forms, images with no alternative text, and misleading link text (Lazar et al., 2007).

Look at that list through a retailer's eyes. Unlabelled forms are your checkout. Missing alt text is your product photography. Misleading links are your "add to basket" and your filters. These are not exotic edge cases in some corner of the site. They sit directly on the path to purchase, which is exactly why they cost you sales rather than mild annoyance. If you want the fastest wins, most of them cluster into six common errors that are cheap to fix once you can see them.

The loss compounds beyond the single lost sale

Two more findings from Click-Away Pound are worth naming, because they change the maths from "one missed order" to "a customer gone for good". First, 83% of shoppers with access needs limit their shopping to sites they already know are accessible (AbilityNet). A checkout that fails once does not just lose today's basket. It removes you from the shortlist for every future basket, because these shoppers plan around the sites that do not let them down.

Second, and this surprises people every time: 86% of disabled shoppers say they would spend more on an accessible site than buy the same thing cheaper on one that is harder to use (AbilityNet). Accessibility is not only a cost of compliance. For a real slice of the market it is a reason to choose you over a cheaper rival, which is about as close to a free margin as retail gets.

Put it together and the pattern is defensive loyalty. A shopper who hits a wall at your checkout has learned something about your brand, and next time they go straight to the competitor that worked. You never witness the moment you lost them, and that invisibility is precisely what makes the £17.1 billion so easy to keep losing.

Common questions

How do I know if my own site is costing me sales this way?

You test the buying journey with assistive technology, not just eyeballs. Run an automated scan to catch the obvious machine-detectable failures, then have someone drive the checkout with a keyboard and a screen reader to catch the ones a scanner misses. The two together tell you where the leak is.

Is fixing accessibility expensive?

Usually far less than the revenue it protects. Many of the highest-impact issues, like unlabelled fields and missing alt text, are small code changes rather than redesigns. The expensive option is leaving a compounding loss in place because it does not show up on a chart.

The way we approach this at AccessPatched is to audit your buying journey against WCAG-EM, test it manually with a screen reader the way your customers do, ship the fixes back to you as pull requests your developers can review and merge, and give you an EN 301 549 conformance statement at the end. If you would rather just start by seeing the damage, the scan below is free. More broadly, this is what our accessibility services are built to fix.

See where your own shop stands. Our free scan runs the same automated checks a regulator's tester starts with, then a human goes through your site with a screen reader and emails you the findings, in plain language. If your shop passes, we say so.
