Use this calculator to calculate and compare the price per unit of a nutrient between two products. Enter price, servings, and units per serving for each product. Click compare. The product with the lower price per unit is the better value.
Products may include food, supplements, or medications. Units may include any value (eg: mcg, mg, grams, IU, ounces, pounds, kg, metric tons, etc.). If the value of two products are being compared, the units for each need to be measured (eg: mg vs mg). Values for a single item can also be entered and calculated.
Servings (per container) and Units per Serving (for the nutrient of interest) can often be found on the Nutrition Fact or Supplement Facts label. For the price, do not include the currency symbol. However, we've included it in the example below for clarity of the numbers.
