Macronutrient Calculator — Overview

The Macronutrient Calculator helps you estimate the ideal daily intake of proteins, carbohydrates, and fats based on your fitness goals, whether it’s weight loss, weight maintenance, or muscle gain. This tool provides a structured approach to nutrition, making it easier to plan meals and meet your dietary targets.

How is it calculated?

The calculator first estimates your total daily calorie requirements based on factors like age, weight, height, gender, and activity level. Then, it distributes these calories among the three macronutrients according to the ratio suited to your chosen goal:


  • Weight loss: Slightly higher protein, moderate carbs, lower fat.
  • Maintenance: Balanced protein, carbs, and fats to sustain current weight.
  • Muscle gain: Higher protein and carbohydrates to support growth, moderate fat.

The calculator outputs your daily target in grams for each macronutrient, making it easy to plan meals.
