What Does 30% DV Mean on a Nutrition Label?

October 28, 2025 •

3 min read

According to the U.S. Food and Drug Administration (FDA), a %DV of 20% or more for a nutrient is considered high. This simple percentage is a powerful tool on the Nutrition Facts label, guiding you to understand the nutritional contribution of a single food serving to your total daily diet, which is especially important for understanding what does 30% DV mean.

Quick Summary

This guide explains the meaning of 30% DV on nutrition labels, detailing how Daily Value percentages reflect a nutrient's contribution to a 2,000-calorie diet and how to use this information to compare products and manage dietary goals. It demystifies the 5/20 rule, high versus low percentages, and other key label elements for confident, informed food choices.

Key Points

Daily Value Basis: The 30% DV figure is based on a standard 2,000-calorie daily diet, used by the FDA to make nutrient information uniform across products.
High Nutrient Source: A 30% DV means a single serving of the food provides 30% of the recommended daily intake for that specific nutrient, making it a high source.
Use the '5/20' Rule: Remember that 20% DV or more is high for a nutrient, while 5% DV or less is low. You can quickly judge a food's nutritional value using this rule.
Evaluate the Nutrient: Whether 30% DV is 'good' or 'bad' depends on the nutrient. It's beneficial for fiber or calcium, but high for sodium or saturated fat.
Manage Your Diet: Use the %DV to make smart dietary trade-offs throughout the day, balancing high-nutrient foods with those you want to limit.

Demystifying the Percent Daily Value (%DV)

On a nutrition facts label, the Percent Daily Value (%DV) helps put a food's nutrient content into context relative to a standard 2,000-calorie diet, which is a general benchmark for nutrition advice. The %DV indicates what percentage of the recommended daily intake for a specific nutrient is provided in one serving. For example, 30% DV for calcium signifies that a single serving contributes 30% of the daily recommended calcium for someone following a 2,000-calorie diet. This high percentage suggests the food is a significant source of that nutrient. In contrast, 5% DV or less indicates a low amount of a nutrient.

The '5/20' Rule of Thumb

The FDA's '5/20' rule is a quick way to interpret %DV.

5% DV or Less is Low: A low %DV means a food contributes a small amount of a nutrient. This is desirable for nutrients to limit, such as saturated fat, sodium, and added sugars.
20% DV or More is High: A high %DV indicates a serving provides a significant amount of a nutrient. Aim for a high %DV for beneficial nutrients like dietary fiber, Vitamin D, calcium, iron, and potassium.

Comparing High vs. Low DV for Different Nutrients

The desirability of a high or low %DV depends on the nutrient. A high %DV for calcium is beneficial, while a high %DV for sodium is not. The label helps you make informed choices.

Nutrients to Get Less Of

Saturated Fat: Limit intake to reduce heart disease risk; aim for low %DV.
Sodium: High intake can raise blood pressure; look for low %DV.
Added Sugars: Limit intake to help meet nutrient needs within calorie limits; aim for low %DV.

Nutrients to Get More Of

Dietary Fiber: Important for digestive health; seek high %DV.
Vitamin D & Calcium: Essential for bone health; look for high %DV.
Iron & Potassium: Support various bodily functions; higher %DV is better.

How Your 30% DV Fits into the Bigger Picture

A 30% DV clearly shows a food's contribution to your daily nutrient intake. If it's a nutrient you need more of, like calcium, one serving covers a significant portion of your daily goal. If it's a nutrient to limit, such as sodium, that serving uses up a notable amount of your daily allowance. You can adjust other food choices accordingly to manage your overall intake.

A Practical Look at Using %DV

Using %DV is about making informed comparisons and dietary trade-offs, not strictly hitting 100% for every nutrient daily. It helps you align food choices with your nutritional goals. For example, if one meal is high in sodium, you can choose lower-sodium options later in the day. The %DV simplifies this balancing act. The 2,000-calorie basis provides a standard for comparing products and quickly identifying foods that are high or low in specific nutrients. By consistently applying the 5/20 rule, you can develop a more effective approach to reading labels and managing your diet.

Comparison of DV Percentages


%DV Range	Interpretation	Best For Nutrients Like...	Avoid For Nutrients Like...
0-5%	Low Source	Saturated Fat, Sodium, Added Sugars	Dietary Fiber, Vitamin D, Calcium
6-19%	Good Source	Dietary Fiber, Vitamins, Minerals	Saturated Fat, Sodium, Added Sugars
20%+	High Source	Dietary Fiber, Vitamin D, Calcium, Iron, Potassium	Saturated Fat, Sodium, Added Sugars

Conclusion

Understanding '30% DV' on a nutrition label provides a clear, standardized snapshot of a food's nutrient content relative to a 2,000-calorie diet. It's a key tool for guiding daily food choices. The '5/20' rule allows for quick assessment of whether a product is a high or low source of a nutrient. This knowledge enables you to balance your intake, prioritizing foods high in beneficial nutrients and limiting those high in components like saturated fat, sodium, and added sugars. Understanding what does 30% DV mean empowers you to make informed decisions for a healthier lifestyle.

Understanding food labels can greatly assist in dietary management.

Frequently Asked Questions

Yes, a 30% DV for a nutrient is considered a high amount. According to the FDA, anything with 20% DV or more is a high source of that nutrient.

The %DV is calculated by dividing the amount of a nutrient in one serving by its official Daily Value and multiplying by 100. For example, if the DV for calcium is 1,300mg, and a serving has 390mg, the %DV is (390/1300) x 100 = 30%.

The 5/20 rule is a quick way to interpret %DV: 5% DV or less is considered low, and 20% DV or more is considered high. Use this to identify foods that are high in beneficial nutrients and low in those you should limit.

No, the %DV is a general guide based on a standard 2,000-calorie diet. Your individual calorie and nutrient needs may differ based on age, gender, and activity level, but the %DV still serves as a useful benchmark.

You don't have to give it up entirely. Use the %DV to make dietary trade-offs. Balance that meal with other foods that are low in sodium during the rest of the day to stay within your daily limits.

Yes, some nutrients like Total Sugars and Trans Fats do not have a %DV because there are no established daily reference values for them. You should use the grams listed on the label instead and aim to limit these.

No. A food might be low in saturated fat and sodium (a good thing), but also low in beneficial nutrients like fiber and vitamins. It's important to look at the overall nutritional profile rather than just one value.
