How is the Nutri-Score A–E rating calculated?
Key takeaway: The rating balances nutrients and ingredients to limit against nutritionally favourable components, normally using values per 100 g or 100 ml.
Nutri-Score is calculated using a points-based nutrient-profiling algorithm. The calculation generally assigns unfavourable points for components whose intake should be limited and favourable points for selected nutrients or ingredients.
Components that can worsen the score
Depending on the product category, the calculation considers:
Components that can improve the score
The calculation may award favourable points for:
The relevant points are combined, and the final numerical result is converted into an A–E classification. The calculation is normally based on the product as sold and expressed per 100 g or 100 ml, rather than relying only on a manufacturer-defined serving size. (Santé Publique France)

A Nutri-Score calculation should not be reconstructed from a package image or marketing claim alone. Businesses need verified recipe, ingredient and nutrition data, together with the correct algorithm for the product category.
For the underlying mandatory values, see the separate guide to the EU nutrition declaration.
What changed in the 2023 algorithm and the 2026 update?
Key takeaway: The algorithm was finalised in 2023; 2026 is primarily an implementation deadline for products using Nutri-Score in Spain, not the date of a new EU-wide algorithm.
The expression “2026 Nutri-Score update” can be misleading. The scientific revision was completed through recommendations adopted for foods in 2022 and beverages in 2023. Spain made the updated calculation applicable from 1 January 2024 and allowed a two-year transition for products already on the market. From 1 January 2026, products sold in Spain that carry Nutri-Score must use the updated algorithm. (Aesan)
Changes affecting general foods
The updated method revised the point scales and rules for several components, including:
It also introduced or refined category-specific treatment for fats, oils, nuts and seeds. Red meat products are subject to a lower maximum protein contribution, intended to align the classification more closely with participating countries’ dietary guidance.
Changes affecting beverages
The revised beverage algorithm:
-
Brings milk-based, fermented milk-based and plant-based drinks into the beverage category.
-
differentiates drinks more closely according to sugar content.
-
Adds unfavourable points where non-nutritive sweeteners are present.
-
Revises the energy, sugar, protein and fruit-and-vegetable components.
-
Changes the thresholds between selected grades.
The scientific committee stated that these changes were intended to improve the classification of low-sugar drinks, sweetened milk-based drinks and beverages containing non-nutritive sweeteners.

Why a product’s grade may have changed
A product that previously carried an A or B may receive a different grade under the revised calculation even when its recipe has not changed. That does not necessarily mean the product itself became less nutritious overnight. It means the method used to assess its nutritional profile changed.
Food businesses should not reuse an old Nutri-Score graphic without recalculating the product. The revised algorithm may affect packaging artwork, product databases, retailer feeds and marketing materials.
Which countries use Nutri-Score?
Key takeaway: Seven European countries participate in Nutri-Score governance, but national implementation dates and administrative procedures are not identical.
The participating countries are:
-
France
-
Belgium
-
Germany
-
Luxembourg
-
Spain
-
The Netherlands
-
Switzerland
Switzerland is not an EU Member State, although it participates in the transnational Nutri-Score governance structure. Santé publique France reports that the updated algorithm took effect in Germany, Belgium, Switzerland and the Netherlands on 1 January 2024, in Luxembourg on 5 March 2024 and in France on 16 March 2025. Spain applied the updated method from 1 January 2024, with its transition ending on 1 January 2026.
Country variations: Nutri-Score registration, notification, transition arrangements and permitted implementation procedures can differ. Businesses selling into several markets should check each competent national authority rather than assuming that one country’s process applies everywhere.
In Spain, the Agencia Española de Seguridad Alimentaria y Nutrición advises operators using or intending to use Nutri-Score to submit the relevant notification and product information through its stated procedure.

Is Nutri-Score mandatory in the European Union?
Key takeaway: Nutri-Score remains voluntary under current EU food-information rules, although businesses choosing to use it must apply the relevant rules accurately.
Nutri-Score is not a mandatory EU-wide food label. Regulation (EU) No 1169/2011 permits additional forms of expression or presentation for nutrition information when the applicable conditions are met, but it does not require every food business to display Nutri-Score.
The European Commission confirms that front-of-pack nutrition information remains voluntary under the current EU framework. It has considered harmonised mandatory front-of-pack labelling as part of a possible revision of the Food Information to Consumers Regulation, but a proposal or policy intention should not be treated as an existing legal obligation. (Food Safety)
The distinction is important:
|
Question
|
Answer
|
|
Must every packaged food in the EU carry Nutri-Score?
|
No
|
|
Can Member States recommend Nutri-Score?
|
Yes
|
|
Can a manufacturer use it voluntarily in participating markets?
|
Yes, subject to the applicable conditions
|
|
Does Nutri-Score replace the mandatory nutrition declaration?
|
No
|
|
Can the displayed grade be approximate?
|
No; it should be calculated using the authorised method
|
|
Does an A grade authorise a nutrition or health claim?
|
No
|
Nutri-Score and promotional claims are separate compliance matters. An A or B grade does not automatically permit wording such as “healthy”, “supports immunity” or “good for your heart”. Claims must be checked independently under Regulation (EC) No 1924/2006, as explained in the guide to nutrition and health claims on food.
What are the benefits and limitations of Nutri-Score?
Key takeaway: Nutri-Score can support rapid comparison, but it is not a complete assessment of health, processing, sustainability or suitability for an individual diet.
Potential benefits
Nutri-Score offers several practical advantages:
-
It turns complex nutrition information into a visible A–E indicator.
-
It supports comparison between similar packaged products.
-
It may encourage product reformulation.
-
It uses a standardised per-100 g or per-100 ml basis.
-
Letters accompany colours, improving usability where colour perception differs.
The European Commission’s review of front-of-pack schemes found that evaluative, colour-coded formats appear promising for helping consumers identify more nutritionally favourable choices. (Food Safety)
Important limitations
Nutri-Score does not measure every characteristic relevant to a purchasing decision. It does not, by itself, indicate:
-
Whether a product is highly processed
-
The environmental impact of production
-
The product’s origin
-
Whether allergens are present
-
Whether a food is suitable for a medical diet
-
The actual quantity a particular consumer will eat
-
The overall balance of a person’s diet
AESAN describes Nutri-Score as a tool for comparing the nutritional composition of similar products and stresses that it does not cover matters such as processing, environmental impact or origin. (Aesan)
The label should therefore be interpreted as a nutritional comparison aid, not as a universal verdict that an A product is always “healthy” or an E product is forbidden.
How should food businesses implement the updated Nutri-Score?
Key takeaway: Implementation requires controlled data, documented calculation, artwork approval and market-specific verification.
A reliable implementation process should include the following steps.
1. Confirm whether Nutri-Score will be used
Document the markets, brands and product groups covered by the decision. Voluntary use should still be governed through a formal internal policy.
2. Verify the product category
Determine whether the general food, beverage, fats-and-oils or another applicable calculation route applies. Incorrect categorisation can change the result.
3. Validate the source data
Use approved specifications, recipe data, ingredient percentages and nutrition values. Check that all values relate to the same product state and measurement basis.
4. Apply the updated algorithm
Do not rely on a historic score, an unofficial online calculator or a competitor’s comparable product. Retain the calculation record and version used.
5. Complete national procedures
Check registration or notification requirements in every country where the product will display Nutri-Score. For products sold in Spain, ensure the post-transition 2026 requirements are met.
6. Control the packaging artwork
Verify that the correct grade, authorised graphic and placement appear on every relevant artwork version. Check digital product listings and retailer data as well as printed packaging.
7. Recalculate after relevant changes
Recipe reformulation, supplier changes, amended nutrition values or an algorithm revision may require recalculation and new artwork approval.
A practical sign-off record should identify the calculation owner, data sources, algorithm version, approval date, target countries and packaging references. This creates evidence that the displayed grade was not selected casually.

Strengthen your food labelling decisions
Key takeaway: Nutri-Score should sit within a wider, documented food labelling approval system.
Understanding front-of-pack ratings is useful, but compliant packaging also depends on mandatory particulars, ingredient declarations, allergens, date marking, nutrition information, origin statements and claims.
