Macro Calculator TDEE: Split Calories into Protein, Carbs & Fat

A macro calculator TDEE pairing is the bridge between knowing how much to eat and knowing what to eat. Your TDEE tells you your daily calorie target; a macro calculator splits those calories into the optimal balance of protein, carbohydrates, and fat.

For weight loss, a common split is 40% protein, 30% carbs, and 30% fat. This higher protein intake preserves muscle while you cut calories. For muscle gain, a 30% protein, 50% carbs, and 20% fat split provides the fuel needed for intense training and recovery. For maintenance, a balanced 30–35% protein, 40% carbs, and 25–30% fat works well for most people.
