Calories & Nutrition
Macro Calculator
Split your daily calorie target across protein, carbohydrates, and fat using sensible preset ratios.
What your result means
None of the splits is uniquely 'correct'. Pick one that matches your preferences and training style and stay consistent.
How we calculate this
Each macro's calorie share is divided by 4 (protein and carbs) or 9 (fat) to get grams.
Limitations
Macro tracking is a tool, not the goal. Aim for ±10 g per macro day to day.
