Sodium — FDA Daily Value
The FDA Daily Value for Sodium is 2,300 mg 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.
A serving with 690 mg of sodium provides 690 ÷ 2,300 × 100 = 30% DV (High).

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 Sodium?
The FDA Daily Value for Sodium is 2,300 mg for adults and children 4 years and older, per 21 CFR 101.9. On a Nutrition Facts label, a serving's %DV for sodium is its amount divided by 2,300 mg, 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 sodium rounded, and when is it declared as zero?
A statement of the number of milligrams of sodium in a specified serving of food expressed as zero when the serving contains less than 5 milligrams of sodium, to the nearest 5-milligram increment when the serving contains 5 to 140 milligrams of sodium, and to the nearest 10-milligram increment when the serving contains greater than 140 milligrams.
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 sodium is in a food?
A Daily Value is a reference target, not a measurement of any particular food. To find the sodium 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.
