Nutri-Score Calculator

Grade a product A to E using the updated 2023 algorithm adopted by the Nutri-Score Scientific Committee, not the superseded 2017 version. Enter the values per 100 g or 100 mL.

Nutri-Score is voluntary and adoption of the 2023 algorithm varies by country, so a product on shelf may still show a 2017 grade during transition. This is a calculation aid, not regulatory approval.

How Nutri-Score is calculated

The basic mechanism

Nutri-Score converts a product's nutrition per 100 g or 100 ml into a single letter from A to E, colour-coded dark green through dark orange. It is a front-of-pack summary intended to let a shopper compare two products in the same category at a glance.

The calculation works by scoring components to limit - energy, saturated fat, sugars and salt - as negative points, then subtracting positive points for components to encourage, such as fibre, protein, and the fruit, vegetable, pulse and nut content. The resulting number falls into a band, and the band is the letter.

The updated algorithm changed the answers

The algorithm was updated for foods in 2022 and for beverages in 2023, and the revision was not cosmetic. Products can and did move grades - the treatment of sugars and salt was tightened, and the handling of certain categories changed materially.

If you calculated a score before the revision and have not recalculated since, do not assume it still holds. This tool implements the updated algorithm.

Separate scales for different products

Beverages, fats and oils, cheeses, and general foods do not all run on the same scale. Beverages in particular have their own stricter thresholds, which is why a drink and a solid food with similar figures can land on very different letters.

Applying the general food scale to a beverage is the most common way of computing a Nutri-Score that looks right and is wrong.

Where it is used, and where it is not

Nutri-Score is voluntary in the countries that have adopted it - France, Belgium, Germany, Spain, the Netherlands, Switzerland, Luxembourg and others. It is not an EU-wide mandate, and it has no standing in the United States.

Because it is voluntary, adopting it is a commercial decision. A product scoring A or B benefits from displaying it; a product scoring D or E generally does not, and no rule compels you to.

Not the same as a warning label

Nutri-Score is a graded comparative scale. The Latin American warning schemes - Mexico's black octagons, Chile's ALTO EN - are mandatory binary marks that appear when a threshold is crossed, and they carry no positive grade at all.

Confusing the two leads brands to assume a good Nutri-Score protects them in a warning-label market. It does not. If you sell into both, calculate both.

Reference information, not legal advice. Requirements change and turn on facts specific to your product - confirm against the current regulation before relying on it.

Common questions

Is Nutri-Score mandatory anywhere?

No. It is voluntary everywhere it is used. France, Belgium, Germany, Spain, Portugal, the Netherlands, Luxembourg and Switzerland officially recommend it; Italy and Poland have opposed it. The European Commission was expected to propose a harmonised mandatory front-of-pack scheme in 2023, but it left the work programme and has not returned, so there is currently no EU-wide requirement.

Which algorithm does this use?

The updated algorithm from the Scientific Committee reports adopted in 2022 for foods and 2023 for beverages. It differs materially from the 2017 original: salt replaces sodium, the sugars and protein scales changed, milk and plant drinks are treated as beverages, nuts and seeds as fats, and sweeteners add a flat penalty to beverages. Adoption of the updated version varies by country, so check which one a given market expects.

Why did my grade get worse under the new algorithm?

That is the expected direction for several categories. The update was designed to be stricter on sugary drinks, on products high in salt, and on some fats and sweetened dairy, and to reward fibre and protein differently. A product that scored well in 2017 and worse now has usually not changed; the scale has.

Do beverages score differently from foods?

Yes, substantially. Beverages have their own scale and their own grade boundaries, water is the only drink that can reach A, and sweeteners add a fixed penalty. Milk and plant-based drinks are assessed as beverages under the updated algorithm, having previously been treated as foods, which moved a lot of grades on its own.

Is a good grade a health claim?

No, and it must not be presented as one. Nutri-Score compares products within the food supply on a fixed formula. It is not a nutrition or health claim under Regulation 1924/2006, it is not a recommendation, and pairing the letter with claim-like wording risks turning a voluntary mark into a regulated statement.
