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

## %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 recommended daily amount of a nutrient someone has consumed.
- TC is the total amount of the nutrient consumed
- DV is the recommended daily value

To calculate a percent daily value, divide the total amount of nutrient consumed by the recommended daily value, 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 recommended daily amount.

## Recommended Daily Nutrient Values

The following table outlines the current recommended daily values of common nutrients.

Nutrient | Daily Amount |

Carbohydrates | 275g |

Fat | 78g |

Protein | 50g |

Sodium | 2300mg |

Sugars | 50g |

Vitamin C | 90mg |

Vitamin D | 20mcg |

Vitamin B6 | 1.7mg |

Zinc | 11mg |

## Example Problem

How to calculate %DV?

**First, determine the total recommended daily value.**For this example, we are looking at carbohydrates, which have a recommended daily value of 275g.

**Next, determine the total amount consumed.**In this case, the person has consumed 300 grams of carbohydrates.

**Finally, calculate the percentage daily value.**Using the formula above, the percent daily value is calculated as:

%DV = TC/DV *100

%DV = 300/275 *100

%DV = %109.1
