FDA rounding rules for nutrition labels

Work out the real number first, then round it by these rules. Never round before you add. Every nutrient has its own floor, and most small amounts become 0.

The rules in one table

Calories, fat, cholesterol, sodium, carbohydrate and protein.

NutrientUnder the floorMiddle rangeUpper range
Caloriesunder 5: can be listed as 05 to 50: nearest 5over 50: nearest 10
Total fat, saturated fatunder 0.5 g: must be 0under 5 g: nearest 0.5 g5 g or more: nearest 1 g
Cholesterolunder 2 mg: can be listed as 0 (or left off if there is no fat or cholesterol claim, with "Not a significant source of cholesterol")2 to 5 mg: can be stated as "less than 5 mg"over 5 mg: nearest 5 mg
Sodiumunder 5 mg: 05 to 140 mg: nearest 5 mgover 140 mg: nearest 10 mg
Total carbohydrateunder 0.5 g: can be listed as 0under 1 g: can say "less than 1 gram"1 g or more: nearest 1 g
Proteinunder 0.5 g: can be listed as 0under 1 g: can say "less than 1 gram"1 g or more: nearest 1 g
Protein has one extra rule: a food with low-quality protein must add "not a significant source of protein" or a corrected % Daily Value (21 CFR 101.9(c)(7)). Most small-batch foods are not affected.
