How to Use This Calculator
  1. Enter grams of protein, fat, total carbohydrate, dietary fiber, and alcohol per serving.
  2. Set serving size in grams and number of servings per container.
  3. The calculator shows total calories per serving, calorie breakdown by macronutrient, calorie density, total container calories, and % Daily Values for fat, protein, and fiber.
  4. Use the % DV values to verify compliance with FDA nutrition label regulations before printing.

Percentage of total calories contributed by protein.
% calories from fat
Percentage of total calories contributed by fat.
% calories from carbs
Percentage of total calories contributed by carbohydrates.
Calorie density (kcal/g)
Energy density — kcal per gram of food. <1.5 low, 1.5–2.5 medium, >4 very high.
Calories per container
Total calories for the entire container.
% DV fat
Percentage of FDA Daily Value for total fat (78 g reference).
% DV protein
Percentage of FDA Daily Value for protein (50 g reference).
% DV fiber

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Protein per serving (g) = 25, Total fat per serving (g) = 10, Total carbohydrate per serving (g) = 40, Dietary fiber per serving (g) = 5 = 7 input(s) provided
  2. Calculate Calories per serving
    Calories per serving = proteinCal + fatCal + netCarbCal + fiberCal + alcoholCal
    340 = 340
  3. Calculate % calories from protein
    29.4 = 29.4
  4. Calculate % calories from fat
    26.5 = 26.5
