Self-checkout loss facts and figures 2026

Self-checkout loss facts

• 54% of all transactions now pass through self-checkout.
• Losses increase by 22% in the year following self-checkout implementation.
• Stores with self-checkout record 33% higher losses.
• Missed scans occur in up to 4.8% of self-checkout transactions.
• Every 10,000 self-checkout transactions generate around 1,000 staff interventions.
• More than 80% of customers correct mistakes when prompted.
• Multiple technology interventions are associated with measurable reductions in loss.

Self-checkout now handles most customer transactions

Self-checkout has become the dominant payment channel in many retail environments. Across the retailers surveyed, 54% of transactions now pass through self-checkout systems, with some retailers reporting utilisation rates as high as 80%.

What began as a labour-saving technology is now a core part of the customer journey. Its scale means even small changes in performance, customer behaviour or loss rates can have a significant impact on profitability.

As self-checkout continues to expand, retailers increasingly need to treat it as a strategic business process rather than simply another checkout option.

Self-checkout increases losses by 22% in the first year

The report analysed data from more than 1,700 stores and found that introducing self-checkout increased losses by an average of 22% during the first year of operation.

On average, this represented a rise of 0.26 percentage points in store losses. While this may appear small, the cumulative financial impact can be substantial when applied across large store networks.

The findings suggest that self-checkout’s labour and convenience benefits need to be weighed against a measurable increase in retail loss.

Stores with self-checkout experience significantly higher losses

When stores operating self-checkout were compared with those that did not, losses were found to be 33% higher in self-checkout locations.

The report also found that self-checkout can account for a growing share of overall loss. One retailer reported that self-checkout was responsible for 28.5% of total retail loss, compared with 9.4% reported in earlier benchmark studies.

These findings suggest that self-checkout is becoming an increasingly important driver of retail loss and should be measured accordingly.

Missed scans remain the biggest source of self-checkout loss

Not all self-checkout losses are equal. The report found that missed scans occur in between 1% and 4.8% of transactions, making them the single most common source of self-checkout loss.

By comparison, walkaways are less frequent but significantly more expensive when they occur. A typical missed scan generates around €2.50 in loss, while a walkaway averages €88 per incident.

Understanding the difference between high-frequency and high-value losses is critical when designing effective interventions.

Self-checkout creates a hidden workload for store staff

Self-checkout is often viewed as a way to reduce labour costs, but it also creates new demands on store teams.

Analysis of 5.7 million transactions found that every additional 10,000 self-checkout transactions generated around:

• 1,000 customer help requests
• 100 payment-related interventions
• 90 walkaway incidents

As transaction volumes increased, staff response times also became slower, creating additional pressure on frontline teams.

Most customers correct mistakes when prompted

One of the report’s most encouraging findings is that many self-checkout losses can be prevented before they occur.

Between 3% and 10% of transactions triggered a customer intervention or “nudge”. When alerted to a missed item, between 80% and 97% of customers corrected the mistake immediately.

These findings suggest that a significant proportion of self-checkout losses stem from error rather than intent, and that well-designed interventions can recover losses without creating friction for customers.

Technology interventions can significantly reduce losses

The report found growing evidence that interventions such as exit gates, personal display monitors and missed-scan detection systems can all reduce self-checkout losses.

Conversely, retailers reported that disabling traditional controls, such as weight verification systems, often led to higher losses.

The findings suggest that retailers do not need to accept self-checkout losses as inevitable. Technology and design choices can materially improve outcomes.
