Nutri-Score Calculator
Enter a food's nutritional values (per 100 g or 100 mL) and find out its Nutri-Score, from A to E. The calculation follows the updated 2023 algorithm.
Calculator
Default setting for most solid foods.
Enter the values shown on the label per 100 g (or 100 mL for beverages).
Your Nutri-Score
Grade A · score 0
A points (to limit): 0 · C points (favorable): 0
Nutri-Score ranges from A (most favorable choice) to E, always calculated on values per 100 g / 100 mL. It's an indicator of overall nutritional quality, not a verdict on a single food within your diet.
What is Nutri-Score
Nutri-Score is a front-of-pack nutrition label that summarizes a food's overall nutritional quality on a single five-level scale, from A (most favorable choice) to E. It originated in France and has since been adopted by several European countries as a voluntary labeling tool, designed to let shoppers compare products in the same category at a glance.
The grade is always calculated on nutritional values per 100 g or 100 mL, making products comparable regardless of serving size. It's an indicator of average nutritional quality, not an absolute verdict: a food with a low grade can still fit into a balanced diet if eaten in the right amounts.
The A–E scale
- AMost favorable nutritional quality.
- BGood nutritional quality.
- CIntermediate nutritional quality.
- DNutritional quality to watch.
- ELeast favorable nutritional quality.
How it's calculated
The score comes from the difference between two groups of components:
- A points (to limit): energy, sugars, saturated fat and salt. The higher these are, the worse the grade.
- C points (favorable): protein, fiber and the percentage of fruit, vegetables and legumes (F&V). These improve the grade.
In short, the final score is A points − C points, with a few specific rules: when the negative points are high, protein is excluded from the count (so as not to "reward" products that are too salty or calorie-dense). The resulting value is then translated into a letter grade using the category's thresholds.
The categories
Thresholds aren't the same for every food: Nutri-Score uses five different tables depending on the category.
- General: all common solid foods.
- Red meat and cold cuts: protein counts for a maximum of 2 points.
- Cheeses: protein always counts.
- Beverages: dedicated tables; the best possible grade is B, only plain water gets an A.
- Oils, fats, nuts and seeds: based on energy from saturated fat and the ratio between saturated and total fat.
Alcoholic beverages are outside the scope of Nutri-Score and get no grade.
Sodium or salt?
Labels may show either sodium (the mineral, in mg) or salt (sodium chloride, in g). The two are linked by salt = sodium × 2.5 (for example, 400 mg of sodium equals 1 g of salt). In the calculator you can enter either one: the conversion is automatic.
The F&V percentage
F&V is the share of fruit, vegetables, legumes, nuts and rapeseed/walnut/olive oil in the product: a favorable component that raises the grade. It's derived from the ingredients list and entered as a percentage (0–100). Note: potatoes and other tubers don't count as vegetables. If you don't know the figure, leave it at 0.
Frequently asked questions
- What is Nutri-Score?
- Nutri-Score is a nutrition label that converts nutritional values into a simple code of five letters (A to E) and matching colors, from dark green for A to red for E.
- How is Nutri-Score calculated?
- The score is worked out by subtracting favorable points (fiber, protein, fruit and vegetables) from points to limit (energy, sugars, saturated fat and salt).
- Which countries use Nutri-Score?
- Nutri-Score has been officially adopted in France, Belgium, Spain, Germany, the Netherlands, Luxembourg and Switzerland.
- How accurate is this tool?
- This calculator follows the official Nutri-Score algorithm published by Santé publique France, including all the special rules for the beverages, fats and red meat categories.
- Can I use this for commercial products?
- Yes: the tool applies the same calculations used for official Nutri-Score labeling, which also makes it useful for quality assurance teams and food industry professionals.
- What does it take to get an A?
- Products high in fiber, protein and fruit/vegetables, while being low in energy, sugars, saturated fat and salt, typically achieve an A or B.
- Why do some categories have different rules?
- Categories such as beverages, fats, cheese and red meat follow dedicated calculation rules that account for their nutritional profile and how they're typically consumed.
- What are the point thresholds for each grade?
- Thresholds vary by category: general foods range from under 1 point (A) to 19 or more (E), beverages use their own thresholds, and plain water automatically gets an A.
