What are FDA rounding rules for nutrition labels?

FDA rounding rules (21 CFR 101.9(c)) specify how nutrient values must be rounded on Nutrition Facts labels. For example, calories below 5 are declared as zero, values between 5-50 are rounded to the nearest 5, and values above 50 are rounded to the nearest 10. Fat below 0.5g is declared as zero, and cholesterol between 2-5mg is declared as "less than 5mg". This calculator applies all FDA rounding rules automatically.

What are the 9 major FDA allergens?

The FDA requires declaration of 9 major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Sesame was added as the 9th major allergen by the FASTER Act of 2021, effective January 1, 2023. This calculator automatically detects these allergens from your ingredient list.

How accurate is this nutrition facts calculator?

This calculator uses nutrient data from the USDA FoodData Central database and applies FDA rounding rules per 21 CFR 101.9(c). However, for commercial food products, FDA requires laboratory analysis (not database calculations) for the Nutrition Facts panel. This tool is designed for preliminary estimation, recipe development, and educational purposes.

Do I need a Nutrition Facts label for my food product?

Most packaged food products sold in the United States require a Nutrition Facts label per FDA regulations. Exemptions may apply for small businesses, certain food service establishments, and foods sold at farmers markets. Consult the FDA website or a regulatory consultant for your specific situation.
