About the Macro Calculator
Turn a daily calorie target into macros free — grams of protein, carbs, and fat. Enter your calories and choose a split (balanced, high-protein, low-carb, or keto) and the calculator does the math: protein and carbs at 4 calories per gram, fat at 9. It's the companion to a calorie (TDEE) calculator — once you know how much to eat, this tells you what those calories should be made of for your goal, whether that's building muscle, cutting, or keto.

How do I find my calorie target?
Use a calorie (TDEE) calculator first to estimate your daily needs, then split those calories into macros here.
What's a good macro split for building muscle?
A higher-protein split (around 40% protein) supports muscle growth. For fat loss, keep protein high to preserve muscle in a calorie deficit.
