Macronutrient Calculator — Protein, Carbohydrates, Fat

The macro calculator determines the optimal calorie split between protein, carbs and fat for your goal.

What are macronutrients?

Macronutrients are the three main energy-providing nutrients: protein (4 kcal/g), carbohydrates (4 kcal/g) and fat (9 kcal/g). Knowing their split allows you to precisely control your diet.

MacronutrientRoleRecommended intake
ProteinMuscle building, satiety1.6–2.4 g/kg
CarbohydratesEnergy, training fuel3–5 g/kg
FatHormones, vitamins0.8–1.2 g/kg

How to use the macronutrient calculator?

First calculate your TDEE in the BMI calculator, then enter the result here. The calculator will automatically compute the optimal grams of protein, carbs and fat based on your goal.

FAQ

How much protein when cutting? Minimum 1.6 g/kg — higher protein intake (2.0–2.4 g/kg) protects muscle mass during a calorie deficit.

Should I count macros or calories? Counting macros is more precise — you automatically control both calories and diet composition. Also check the progress chart.

What is a Macronutrient Calculator?

A macronutrient calculator determines your optimal daily amounts of protein, carbohydrates and fat based on your caloric needs and goal. Tracking macros goes beyond calorie counting — it lets you control body composition, losing fat while preserving or building lean muscle.

Frequently Asked Questions

Is tracking macros better than counting calories?For body composition, yes. Same calories with different macro splits produce very different body composition outcomes.
Do I need to hit macros exactly every day?Aim for weekly averages rather than daily perfection. Flexibility improves long-term adherence.
How much protein do I actually need?1.6–2.2 g/kg/day for active adults. Up to 3 g/kg during aggressive cutting to preserve muscle.
