How to Calculate Percent Daily Value for a Nutrition Label

How to calculate percent Daily Value: the Daily Values for fat, sodium, fiber, protein, added sugars, calcium and iron, the formula, rounding, a calculator.

Percent Daily Value is the amount of a nutrient in a serving divided by its Daily Value, times 100. The Daily Values are set by FDA for adults and children 4 and older: total fat 78 g, saturated fat 20 g, cholesterol 300 mg, sodium 2,300 mg, total carbohydrate 275 g, dietary fiber 28 g, added sugars 50 g, protein 50 g, and for the four required minerals and vitamin, vitamin D 20 mcg, calcium 1,300 mg, iron 18 mg and potassium 4,700 mg. Macronutrients round to the nearest whole percent; vitamins and minerals round to the nearest 2% up to 10, 5% up to 50, and 10% above. Protein's %DV is optional unless you make a protein claim, and then it's corrected for protein quality. In the example below, a Wisconsin yogurt maker works out its labels.

The short version

  • %DV = amount in a serving ÷ Daily Value × 100.
  • Fat 78 g, saturated fat 20 g, sodium 2,300 mg, carbs 275 g, 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.
  • Macronutrients: nearest whole percent.
  • Vitamins and minerals: nearest 2% to 10, 5% to 50, 10% above.
  • Protein %DV is required with a protein claim, corrected for quality.
  • TaroStack keeps each recipe by weight, so a batch's ingredients are on record. More below.

The Daily Values

Nutrient Daily Value
Total fat 78 g
Saturated fat 20 g
Cholesterol 300 mg
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

What a %DV lets a label claim, such as "good source of calcium" at 10% to 19%, is in good source of calcium, and rounding the amounts first in nutrition label rounding rules.

The rules

Rule Where
Daily Reference Values Fat 78 g, saturated fat 20 g, cholesterol 300 mg, carbohydrate 275 g, sodium 2,300 mg, fiber 28 g, protein 50 g, added sugars 50 g (21 CFR 101.9(c)(9))
Reference Daily Intakes Vitamin D 20 mcg, calcium 1,300 mg, iron 18 mg, potassium 4,700 mg, among others (101.9(c)(8)(iv))
Vitamin and mineral rounding Nearest 2% up to and including 10%, nearest 5% above 10 up to 50, nearest 10% above 50 (101.9(c)(8)(iii))
Other nutrients Nearest whole percent, dividing the declared or the unrounded amount by the Daily Value (101.9(d)(7)(ii))

An example: a high-protein yogurt

Prairie Hollow Creamery, the made-up yogurt maker in Mount Horeb, Wisconsin, I use in these examples, worked out the %DV for a 170-gram cup of its new plain high-protein yogurt:

Nutrient Amount Daily Value %DV on the label
Total fat 4 g 78 g 5%
Saturated fat 2.5 g 20 g 13%
Cholesterol 15 mg 300 mg 5%
Sodium 65 mg 2,300 mg 3%
Total carbohydrate 7 g 275 g 3%
Added sugars 0 g 50 g 0%
Protein 17 g 50 g 34% before the quality correction
Calcium 200 mg 1,300 mg 15%
Potassium 240 mg 4,700 mg 6%

Calcium works out to 15.4%, which rounds to the nearest 5% above 10, so 15%; potassium is 5.1%, rounded to the nearest 2%, so 6%. Protein's %DV is shown because the cup says "high protein", and the 34% is corrected for protein quality before it goes on the label; milk protein scores near the top, so the correction is small. The yogurt's year is in yogurt business plan.

Download the percent Daily Value calculator. One sheet: each nutrient, its amount per serving, its Daily Value and whether it's a vitamin or mineral; the %DV and the rounded figure for the label fill in. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.

Where this stops working

The calculator divides what you give it. The amounts come from the recipe, and a recipe change from 2% milk to whole changes the fat line on every cup.

How TaroStack does it

TaroStack keeps each yogurt as a recipe by weight, so the ingredients behind its label are on record for every batch.

Recipes by weight. Each yogurt is a recipe by weight: milk, cultures and any fruit.

Batches from the recipe. Each batch records the recipe it followed and the ingredient lots it used.

Recalls. If a batch went out with the wrong label, one report shows every customer who got it.

Which recipe a batch followed Remembered Each batch from its recipe
A recipe change that alters the label Noticed late The recipe on record
Who got a mislabeled batch Invoices One recall report

Recipes, batches and recalls are on every plan, from $49 a month. The first 30 days are free, with no credit card. If you'd like a hand setting up, ask, and we'll do it with you.

Questions people also ask

How do you calculate percent Daily Value?

Divide the amount in a serving by the nutrient's Daily Value and multiply by 100.

What is the Daily Value for sodium?

2,300 milligrams for adults and children 4 and older.

How is %DV rounded for vitamins and minerals?

To the nearest 2% up to 10%, the nearest 5% up to 50%, and the nearest 10% above.

Is %DV for protein required?

Only when the label makes a protein claim, or the food is for young children; then it's corrected for protein quality.
