%DV Calculator (Percent Daily Value)

Select a nutrient from the drop-down box and enter the quantity into the calculator to determine the percent daily value (%DV).

Note: This calculator uses Daily Values (DV) used on FDA Nutrition Facts labels (generally for ages 4+ and many are based on a 2,000‑calorie diet). DVs are reference amounts for labeling—not personalized nutrition targets. The “Custom Daily Value” tab is a math helper for comparing to a limit/goal you choose; for individualized advice, consult a clinician or registered dietitian. For the official DV list and context, check the FDA website.

%DV Formula

The following formula is used to calculate a percentage daily value of a nutrient.

PDV = TC / DV *100

• Where PDV is the percentage of the Daily Value (DV) someone has consumed.
• TC is the total amount of the nutrient consumed
• DV is the Daily Value (DV) reference amount used on Nutrition Facts labels

To calculate a percent daily value, divide the total amount of nutrient consumed by the Daily Value reference amount, then multiply by 100.

Percent Daily Value Definition

A percent daily value, or %DV for short, is a term used to describe the ratio, in terms of a percent, of the total amount of a nutrient someone has consumed with respect to the Daily Value (DV) reference amount.
