How to Read % Daily Value on Nutrition Labels

Quick Answer

Percent Daily Value (% DV) on a nutrition label shows how much of each nutrient one serving contributes to a 2,000-calorie reference diet. The FDA uses a simple interpretation guide: 5% DV or less is "low" for a nutrient; 20% DV or more is "high." For nutrients you want more of (fiber, vitamin D, calcium, iron, potassium), higher % DV is better. For nutrients you want less of (saturated fat, sodium, added sugars), lower % DV is better. Some nutrients (trans fat, total sugars, protein) lack established Daily Values and show no % DV column.

Most people see "% Daily Value" on every food label they read — and most don\'t know how to use it. The FDA designed % DV as a quick-glance tool to compare products and identify what to consume more of and less of. This short guide explains how it works and how to apply it.

The 5% / 20% Rule

The FDA\'s standard interpretation:

5% DV or less per serving = "low" in that nutrient. Useful for limit nutrients (sodium, saturated fat, cholesterol, added sugars).
20% DV or more per serving = "high" in that nutrient. Useful for nutrients to maximize (dietary fiber, vitamin D, calcium, iron, potassium).
Between 5% and 20% = "moderate" — not particularly notable in either direction.

The 2,000-Calorie Reference Diet

All % DVs are based on a 2,000-calorie reference diet. The FDA acknowledges that caloric needs vary by age, sex, activity level, and other factors — but standardizes on 2,000 for label calculations to enable cross-product comparison.

Daily Values for the major nutrients:

Nutrient	Daily Value	Goal
Total Fat	78 g	Limit
Saturated Fat	20 g	Limit
Sodium	2,300 mg	Limit
Dietary Fiber	28 g	Maximize
Added Sugars	50 g	Limit
Calcium	1,300 mg	Maximize
Vitamin D	20 mcg	Maximize
Iron	18 mg	Maximize
Potassium	4,700 mg	Maximize

Why Some Nutrients Have No % DV

Three categories of nutrients lack established Daily Values:

Trans Fat — the goal is zero consumption, so no DV is meaningful. The label shows grams only.
Total Sugars — the FDA decided a single DV would be misleading because sugars from whole fruit are nutritionally different from added sugars. Total Sugars shows grams only; Added Sugars (separate line) has a DV of 50g.
Protein — typically shown without % DV unless a protein claim is made. The FDA reasoned that protein intake is rarely deficient in the U.S., so a % DV was unnecessary for everyday labeling.
Botanicals and herbs on Supplement Facts panels — DV not established for most herbs, marked with † symbol.

Calculating % DV for Your Product

Simple formula: (amount per serving ÷ Daily Value) × 100, rounded to nearest whole percent.

Example: 850 mg sodium per serving = (850 ÷ 2,300) × 100 = 36.96%, rounded to 37% DV.

Frequently Asked Questions

What does 5% DV vs 20% DV mean?

5% DV or less per serving means the food is a "low" source of that nutrient — useful for tracking limits (sodium, sat fat). 20% DV or more per serving means the food is a "high" source — useful for tracking nutrients you want more of (fiber, calcium, iron). The 5/20 rule is the FDA's standard interpretation framework communicated in consumer education materials.

How is % Daily Value calculated?

For each nutrient, divide the per-serving amount by the FDA Daily Value reference, multiply by 100, and round to the nearest whole percent. Example: 12g fat per serving = (12 ÷ 78) × 100 = 15.4%, rounded to 15% DV. The 78g reference is the FDA Daily Value for total fat (updated in 2020 from 65g).

Why do some nutrients lack % DV?

The FDA hasn't established Daily Values for all nutrients. Trans fat has no DV (the goal is to consume zero). Total sugars has no DV (the FDA reasoned that some sources are healthy and some aren't, so a single value isn't meaningful). Protein has no DV unless a protein claim is made on the label. Most herbs and amino acids on Supplement Facts panels also lack DVs (marked with †).

Is % DV based on my actual diet or a reference?

A 2,000-calorie reference diet. The FDA notes that "calorie needs vary" but standardizes on 2,000 for label calculations. Children, athletes, elderly adults, and others with different caloric needs would need to scale % DV up or down for personal use — but the label cannot be customized.

Should I aim for 100% DV daily for each nutrient?

For "good" nutrients (fiber, vitamins, minerals) — yes, reaching 100% across all your food is a reasonable target. For "limit" nutrients (saturated fat, sodium, added sugars) — staying under 100% is the goal, not reaching it. Sodium's 100% DV is 2,300 mg — exceeding that daily is associated with elevated blood pressure.

How accurate are % DVs on labels?

They're directly calculated from declared nutrient amounts, so accuracy depends on the accuracy of the underlying values. FDA tolerance is typically ±20% for declared amounts, which translates to ±20% on % DV calculations. For products using lab-tested values, % DV accuracy is ±2-5%. For products using calculated USDA database values, ±5-15% for macronutrient DVs.
