The number of servings per container is the first line on a Nutrition Facts panel unless it is a single serving, which allows omitting that information. Determining the number of servings per container is straightforward, but there are nuances when rounding is applied. 

Basic rounding rules apply to the servings per container on a Nutrition Facts panel if the number of servings isn’t an exact whole number. 

Whole number rounding applies when there are less than two or greater than five servings per container. Below are examples of how to follow whole-number rounding.

• .5 to 1.49 round to 1
• 1.5 to 2.49 round to 2
• 4.5 to 5.49 round to 5
• 5.5 to 6.49 round to 6

Half-number rounding applies when the number of servings is between two and five. Below are examples of how to follow half-number rounding.

• 2.25 to 2.74 round to 2.5
•  2.75 to 3.24 round to 3
• 3.25 to 3.74 round to 3.5
• 3.75 to 4.24 round to 4

Use “about” on the servings per container when applying half-number rounding rules. For example, “about 2.5 servings per container.”

For more details on the servings per container, refer to the FDA Title 21 CFR and search 101.9 (8)(i).
