About Daily Value Percentage Calculator

Percent daily value is the amount in a serving divided by the reference daily value; multiplying by the servings actually eaten gives the real contribution. Labels report per serving, so eating two servings of a 'good source' food quietly doubles the percentage, which is where sodium and saturated fat targets get missed.

Formulas

Percent DV

% DV = amount per serving / reference daily value x 100

Actual intake

total % = % DV x servings eaten

  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
