How Macronutrient Percentages are Calculated

Each macronutrient provides a specific energy density per gram:

  • Protein: 4 calories per gram
  • Carbohydrates: 4 calories per gram
  • Dietary Fat: 9 calories per gram
Macro Percentage Formulas
Total Calories = (Protein × 4) + (Carbs × 4) + (Fat × 9)
% Protein = (Protein × 4 / Total Calories) × 100%
% Carbs = (Carbs × 4 / Total Calories) × 100%
% Fat = (Fat × 9 / Total Calories) × 100%
