Protein — FDA Daily Value
The FDA Daily Value for Protein is 50 g for adults and children 4 or more years of age — a Daily Reference Value (DRV) scaled to a 2,000-calorie diet. It changes by population group; see the exact numbers below.
Protein rounding rules
Amount
Protein is declared to the nearest 1g — measuring finer than that changes nothing on the label.
| Amount range | Rounding rule |
|---|---|
| 0 to <0.5 | declared as 0g |
| 0.5 to <1 | less than 1g |
| ≥1 | nearest 1g |

How much Protein is behind each %DV?
What a serving has to contain for a label to print each figure. The %DV is worked out from the actual amount, before that amount is rounded.

The rules are FDA's; the inversion is ours. Ranges are inclusive at the low end and exclusive at the high end, because an exact half rounds up.

Frequently asked questions
Every figure on this page traces to a paragraph of 21 CFR 101.9. These are those paragraphs, in full.
What is the FDA Daily Value for Protein?
The FDA Daily Value for Protein is 50 g for adults and children 4 years and older, per 21 CFR 101.9. On a Nutrition Facts label, a serving's %DV for protein is its amount divided by 50 g, times 100.
Is %DV calculated from the declared amount or the actual amount?
The percent shall be calculated by dividing either the amount declared on the label for each nutrient or the actual amount of each nutrient (i.e., before rounding) by the DRV for the nutrient, except that the percent for protein shall be calculated as specified in paragraph (c)(7)(ii) of this section.
How is protein rounded on a Nutrition Facts label?
A statement of the number of grams of protein in a serving, expressed to the nearest gram, except that if a serving contains less than 1 gram, the statement "Contains less than 1 gram" or "less than 1 gram" may be used as an alternative, and if the serving contains less than 0.5 gram, the content may be expressed as zero.
Where do the Daily Values for macronutrients come from?
The following DRVs, nomenclature, and units of measure are established for the following food components:
Note: The Daily Value itself is listed in the DRV table this paragraph introduces, not restated as prose.
How do I find out how much protein is in a food?
A Daily Value is a reference target, not a measurement of any particular food. To find the protein content of a specific ingredient or product, look it up in USDA FoodData Central, then use that amount here to see what a label would declare and what %DV it carries.
