What the % Daily Value on a Food Label Means
The % Daily Value shows how much one serving adds toward a day's nutrient amount on a 2,000-calorie diet. 5% or less is low, 20% or more is high. How to use it.

The % Daily Value, or %DV, tells you how much one serving of a food contributes toward a full day’s amount of a nutrient, based on a 2,000-calorie diet. FDA’s rule of thumb is simple: 5% DV or less is low, and 20% DV or more is high. You don’t have to do any math to use it; just glance down the right-hand column.
Where the numbers come from
FDA sets a reference amount, called a Daily Value, for each nutrient on the label. The %DV is one serving’s share of that amount. For adults and children 4 and older, the Daily Values include:
| Nutrient | Daily Value |
|---|---|
| Saturated fat | 20 g |
| Sodium | 2,300 mg |
| Total carbohydrate | 275 g |
| Dietary fiber | 28 g |
| Added sugars | 50 g |
| Protein | 50 g |
| Vitamin D | 20 mcg |
| Calcium | 1,300 mg |
| Iron | 18 mg |
| Potassium | 4,700 mg |
Daily Values are not personal targets. They’re a shared yardstick so that a box of crackers and a can of soup can be measured against the same scale. Some, like sodium, are upper limits to stay under; others, like fiber and calcium, are amounts to reach.
The 5–20 rule in practice
Use the two markers depending on the nutrient.
Aim higher (closer to 20% DV or more) for:
- Dietary fiber
- Vitamin D
- Calcium
- Iron
- Potassium
Aim lower (closer to 5% DV or less) for:
- Saturated fat
- Sodium
- Added sugars
The Dietary Guidelines have flagged fiber, calcium, vitamin D and potassium as nutrients many Americans don’t get enough of, and all four are required on the label.
Comparing two products
Say two jars of pasta sauce sit side by side. One lists 20% DV for sodium per half-cup; the other lists 12% (numbers here are just for illustration). With the same serving size, the second jar gives you noticeably less sodium per bowl of pasta. That’s the real strength of %DV: quick, fair comparisons within the same aisle.
The same trick works for nutrients you want more of. A cereal that provides 20% DV for fiber per serving is a high-fiber pick; one at 4% is low. A yogurt with 25% DV for calcium is doing far more for your bones than a dessert cup at 6%.
The catch is that the serving sizes have to match. If one cereal’s serving is ¾ cup and another’s is 1¼ cups, the percentages aren’t describing the same amount of food. Check the serving line first, then compare.
%DV also helps with trade-offs during the day. If lunch was a high-sodium sandwich at 40% DV, a dinner built on fresh vegetables and plain grains keeps the day in balance.
What the %DV doesn’t tell you
- Trans fat and total sugars have no %DV. Total sugars include the natural sugar in milk and fruit; the “Includes Added Sugars” line beneath it does carry a %DV.
- Protein is usually shown in grams only. A %DV is required when the package makes a protein claim or the food is meant for children under 4.
- Your personal needs. A teenager, a pregnant woman and a 75-year-old man need different amounts of many nutrients. The DV is an average reference.
- Every vitamin and mineral. Only vitamin D, calcium, iron and potassium are required. Others, such as vitamins A and C, appear when a company chooses to list them, adds them to the food or makes a claim about them.
- What the food is made of. The panel won’t tell you whether the flour is whole grain or what kind of sweetener was used. That’s the job of the ingredient list, covered in our guide to reading an ingredient list.
If you eat more or less than 2,000 calories
The 5% and 20% markers still work for comparing foods no matter how much you eat. What changes is the share of your own day. For nutrients tied to calories, such as total fat, saturated fat, carbohydrate and added sugars, a smaller eater’s day holds less, so each percentage point takes up a bigger slice. A larger, very active person has more room. Sodium is different: its Daily Value is a fixed limit that doesn’t rise with calories.
A 20-second label routine
- Read the serving size and the number of servings in the package.
- Note the calories per serving.
- Run your eye down the %DV column, looking for anything at 5% or below and 20% or above.
- Check saturated fat, sodium and added sugars against the low end.
- Check fiber, vitamin D, calcium, iron and potassium against the high end.
If added sugars stand out, our list of the names for added sugar shows where they hide in the ingredients.
Remember 5 and 20
You don’t need to memorize every Daily Value. Hold on to two numbers: 5% is low, 20% is high. Match serving sizes before comparing, and use the ingredient list to fill in what the numbers can’t show.
Common questions
Why is the %DV based on 2,000 calories?
It's a round reference figure FDA uses so every label works the same way and products are easy to compare. Your own needs may be higher or lower, but the percentages still tell you whether a food is relatively high or low in a nutrient.
Is 20% DV of sodium in one serving a lot?
By FDA's rule of thumb, yes: anything at 20% DV or more counts as high. One serving at that level uses a fifth of the day's sodium limit, so it helps to keep other meals that day on the lighter side.
Can I add up %DV across the day?
As a rough check, you can. Keeping the daily total under 100% for sodium, saturated fat and added sugars keeps you within those limits. For fiber, calcium, potassium and other nutrients you want more of, higher totals are generally better, though individual needs differ.
