When costs change, the first instinct might be to try to pass them on in retail prices. However, the latest data show just how much more complex this equation has become.
In August 2026, according to INSEE, the purchase prices for agricultural inputs rose by 8.2% year-over-year. The increase amounted to 10.0% for intermediate consumption and 50.5% for energy. These indicators measure changes in the prices of goods and services used by farmers and thus provide insight into upstream price pressures.
At the same time, agricultural producer prices showed very mixed trends across different categories: +22.1% for grains, +18.0% for fresh vegetables , and +38.0% for corn, while milk fell by 10.0% and those for adult cattle by 4.0%.
These developments illustrate a key reality: cost pressures upstream do not lead to identical price dynamics across categories, nor do they necessarily result in the same pricing decision for a retailer.
Passing on a cost increase is not an automatic decision
An increase in purchase costs automatically puts pressure on margins. But adjusting a selling price requires looking well beyond just the cost.
How price-sensitive are consumers to this product? How does the retailer compare to its competitors? Does the product play an important role in the price image? Is there a risk that a price increase could cause customers to switch to another product or another retailer?
Two products facing the same increase in costs may therefore require very different pricing decisions.
A 5% increase in costs therefore does not necessarily lead to a uniform 5% increase in prices. A retailer may choose to pass on a larger portion of the increase to certain items that are less price-sensitive, maintain prices on key products that are critical to its price image, and temporarily accept pressure on margins for certain items that are particularly exposed to competition.
The decision involves balancing several objectives
Pricing is precisely about striking a balance between several factors that are sometimes contradictory:
preserve the margin, without causing an excessive decline in sales volume;
maintain its competitiveness, without systematically adopting an approach of alignment;
protect its price image, particularly for products that are highly visible or frequently compared;
take demand into account, since not all categories exhibit the same elasticity;
anticipate competitors’ reactions, rather than making a decision based solely on internal costs.
Cost is therefore an important factor, but it cannot be the sole factor in determining pricing.
A rise in costs should therefore not be interpreted as an automatic signal to raise prices. It is, above all, a signal that must be analyzed in light of other factors: profit margins, demand sensitivity, competitive positioning, the role of the benchmark in price perception, and business objectives.
In other words, a cost increase is a pricing signal, not automatically a price increase. Decisions must continue to be tailored to specific products, categories, and related issues.
Price, Margin, and Competition: How to Balance Them?
In a volatile environment, pricing performance therefore depends less on the ability to react quickly to rising costs than on the ability to strike the right balance in terms of granularity.
The same change in cost does not necessarily justify the same decision across different categories and product lines. Purchase costs, margin, competitors’ prices, sales history, price elasticity, and the product’s role in price perception must all be analyzed together.
Today, pricing tools make it possible to consolidate this data, identify products that require a decision, and—when the data allows—simulate different price, margin, and volume scenarios.
So the question is no longer just:
“By how much should we raise our prices?”
It becomes:
“Which products should we focus on, to what extent, and what impact can we expect on margins, volumes, and our competitive positioning?”
