Macronutrient Calculator Formula / How It Works

The calculator distributes target calories by ratio percentages, converting protein/carbs at 4 calories/gram and fats at 9 calories/gram.

Formula:Protein: 4 kcal/g. Carbs: 4 kcal/g. Fat: 9 kcal/g. Grams = (Calorie * ratio) / kcal_per_gram.
Example Calculation:

For example, let's look at a daily target of 2,000 calories with a balanced macro ratio (40% carbs, 30% protein, 30% fat). By entering these values into the tool, you will get daily macronutrient goals of 200g of carbohydrates, 150g of protein, and 67g of dietary fat instantly.
