PRICE GAP
Price gap
Price variance measures the difference between a product's price in a retail banner and a reference price: market average, direct competitor price, substitutable reference price, or historical period price.
It is expressed in absolute value (in currency units) or as a percentage. It is one of the most closely monitored Pricing KPIs because it consolidates competitive positioning or product evolution into a single metric.
An average gap that masks a category that falls outside the norm
Gardening — 800 products tracked compared to 3 competitors
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
Why is this important to know?
- Synthesize competitive positioning: evaluate a category into a single metric easily understood by all departments (sales, finance, marketing).
- Detect pricing drifts rapidly: a gap widening by 2 points within a month should trigger an in-depth analysis or corrective action.
- Support commercial commitments: maintaining "a maximum price gap of -3% vs competitor A" establishes a measurable target.
- Alimenter l'index prix : agrégé sur un panier de références, l'écart de prix calculé produit par produit est la brique de base de l'index prix global de l'enseigne.
Example
A garden center tracks its price variance across 800 core SKUs against three competitors. The median variance is +1.2% (indicating the retailer is slightly higher priced).
In the "power tools" category, the variance climbs to +4.8%, degrading price perception on a high-traffic category.
A targeted repricing action brings the variance back to +1.5% within three weeks, with an estimated margin cost of 0.4 pts on the category, offset by a 9% volume increase.
Common pitfalls to avoid:
- Relying solely on averages: which can mask problematic extreme variances on Key Value Items (KVIs).
- Comparing gaps across categories: without accounting for differing price sensitivities (a 5% shift in staple groceries is more problematic than a 5% shift in apparel).
- Reacting to every fluctuation: without examining the root cause (a competitor's temporary promotion does not justify permanent alignment).
FAQ
Price variance corresponds to the observed price difference between a product and a competitor's, or between two comparable products
This metric evaluates a retailer's pricing positioning and identifies adjustment opportunities to enhance competitiveness or profitability.
Price variance can be expressed in absolute value (in currency) or as a percentage
It is calculated by comparing a product's price against a competing reference or target price
This measurement allows for precise tracking of positioning gaps in a given market.
Monitoring price variances helps pricing teams preserve their competitiveness on strategic products, detect competitor movements, and adjust pricing policies
It also contributes to maintaining a consistent price image among consumers.
No
A price variance may be intentional to reflect a higher level of service, a stronger brand equity, or an upmarket strategy
The objective is not to systematically match competitor prices, but to justify each variance with a clear commercial strategy.
Pricing solutions automate competitor price scraping, product matching, and price variance calculations
They generate alerts for significant fluctuations and provide simulations to assist pricing teams in making rapid, data-driven decisions.

Price perception is a subjective view shaped by a brand’s key 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? Just 2% of a brand’s products account for 80% of its price perception.
A price-monitoring pipeline that continuously tracks competitors’ prices does not protect the price image if it is followed by a simple reflex:automatically aligning the entire catalog with the lowest price detected. This destroys both the margin and the price image, because customers actually compare only a small portion of the products—the showcase products (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 losing sales volume —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.
