How percent daily value is calculated
Many of the nutrient amounts in the nutrition facts table are shown using % DV.
The current daily values are based on 2 sets of values. These include the:
- recommended daily intake (RDI) for vitamins and minerals
- reference standards for:
- saturated and trans fats
The % DV for a nutrient is calculated by:
- dividing the amount of a nutrient in a serving size by its daily value, then
- multiplying that number by 100
For example, a food product has 3 mg of iron. The daily value for iron is 14 mg. This means that the % DV for iron would be 21%.
If you would like to do your own calculation, use the equation below to help you.
(3 mg ÷ 14 mg) × 100 = 21% DV
|Nutrient||Daily Value (DV)|
|Note: RE = retinol equivalents|
|Saturated and trans fats||20 g|
|Vitamin A||1000 RE|
|Vitamin C||60 mg|
