Daily Value Formula:
| From: | To: |
The Daily Value Calculator 2025 calculates the percentage of the recommended daily amount (%DV) of a nutrient based on the updated 2025 Recommended Dietary Allowance (RDA) values. This helps individuals understand how much a serving of food contributes to their daily nutrient requirements.
The calculator uses the Daily Value formula:
Where:
Explanation: The equation calculates what percentage of the daily recommended amount is provided by a specific quantity of a nutrient.
Details: Calculating %DV helps consumers make informed food choices, understand nutritional content, and maintain balanced diets according to the latest nutritional guidelines.
Tips: Enter the nutrient amount in mg and the updated 2025 RDA value in mg. Both values must be positive numbers.
Q1: What is the difference between DV and RDA?
A: RDA (Recommended Dietary Allowance) is the daily intake level sufficient to meet nutrient requirements, while DV (Daily Value) is the percentage of that requirement provided by a food serving.
Q2: Why are RDA values updated?
A: RDA values are periodically updated based on new nutritional research, changing dietary patterns, and improved understanding of human nutritional requirements.
Q3: How often are RDA values revised?
A: RDA values are typically reviewed and updated every 5-10 years by health authorities to reflect current scientific knowledge.
Q4: Are Daily Values the same for all nutrients?
A: No, Daily Values vary by nutrient type. Different vitamins, minerals, and macronutrients have different recommended daily amounts.
Q5: Can Daily Value exceed 100%?
A: Yes, it's possible for a food to provide more than 100% of the Daily Value for certain nutrients, especially in fortified foods or supplements.
