Which category is driving up your average deviation?
Schedule a meetingDiscover our pricing optimization softwareThe price gap measures the difference between a product’s price at a retail outlet and a benchmark price—such as the average market price, the price of a direct competitor, the price of a substitute product, or the price from a previous period. It is expressed in euros or as a percentage and summarizes a product’s market position in a single figure.

The difference between your price and a reference price.
Pricing, sales management, finance, marketing.
Continuous monitoring; a 2-point deviation over the course of a month should raise a red flag.
By reference, category, and competitor.
Identify deviations and set measurable goals.
(Your price − reference price) ÷ reference price, as a percentage.
Because it summarizes the competitive position of a product or category in a single number that is easy for all departments to understand.
It is one of the most closely monitored pricing KPIs.
A gardening retailer with an average increase of 1.2% reports a 4.8% increase in power tools.

price difference in the power tools category, compared with a median increase of 1.2% across the entire basket.
Gap Narrowed in 3 Weeks Following a Targeted Repricing
Volume increased, with a margin cost of 0.4 points
Across 800 monitored products compared to 3 competitors, this high-traffic category negatively impacts price perception. Targeted repricing reduces the gap to +1.5% within three weeks, with a 0.4 percentage point margin offset by a 9% increase in volume.
In euros or as a percentage relative to a selected benchmark, then tracked over time by category.

| Difference in value | Your price − reference price |
| Percentage Difference | (Your price − reference price) ÷ reference price × 100 |
Reference prices are derived from your competitors’ price lists; our price optimization software calculates price discrepancies, alerts you to deviations, and simulates corrections. A price discrepancy does not need to be corrected if it is intentional (e.g., for service or brand reasons)—it simply needs to be justified.
Looking at the average alone, comparing different categories, or reacting to every change.
Short answers to the most frequently asked questions about price differences.
The price gap measures the difference between the price of a product at a retail outlet and a benchmark price: the average market price, the price of a direct competitor, the price of a substitute product, or the price from a previous period. It is expressed in euros or as a percentage.
By comparing the price of a product to that of a competitor's product or a target price, either in absolute terms (euros) or as a percentage of the reference price.
No. A price difference may be intentional to reflect better service, a stronger brand, or a move upmarket. The key is that every price difference be justified by a clear strategy.
They automate the collection of competitors' prices, product linking, and the calculation of price differences; they generate alerts in the event of significant changes and simulate possible adjustments.

Price perception is a subjective perception driven by flagship products (KVI), not by an overall statistical average. For the reader, mastering this lever makes it possible to build customer loyalty without sacrificing overall profitability. A key point? Only 2% of products account for 80% of a retailer’s price perception.
The goal of BOOPER’s Price Assessment is to objectively evaluate this perception rather than speculate about it: to thoroughly analyze your positioning relative to the competition, product by product.
A price-monitoring pipeline that continuously tracks competitors’ prices does not protect your price image if it is followed by a simple reflex: automatically aligning the entire catalog with the lowest price detected. This destroys both your margin and your price image, because customers actually compare only a small portion of the products—the showcase items (KVI).
Retailers that carefully curate their window displays rather than stocking their entire catalog gain an additional 1 to 2 percentage points in margin—without any loss in volume—and up to 2 percentage points at an Eastern European chain studied by McKinsey.

Strategic pricing defines long-term positioning to maximize profitability and price image, unlike daily operational adjustments. This framework structures range architecture and governance to prevent gut-feeling decisions. In retail, 62% of buyers prioritize price, making this compass essential for protecting margins against competition.
