Calories are important for fat loss or muscle gain — but they’re only part of the picture. The next step? Understanding your macronutrient breakdown: how much protein, carbs, and fat you should be eating each day.
That’s where our free Macro Split Calculator comes in. It takes your daily calorie goal and shows you exactly how to divide those calories into the macros your body needs to hit your goal — whether it’s fat loss, muscle gain, or maintenance.
⚖️ What Are Macros?
Macros (short for macronutrients) are the 3 main nutrients that supply calories:
| Macronutrient | Function | Calories/Gram |
|---|---|---|
| Protein | Builds & repairs muscle | 4 kcal |
| Carbs | Provides quick energy | 4 kcal |
| Fat | Supports hormones & satiety | 9 kcal |
The right balance of macros can make a big difference in your energy, recovery, and how your body responds to your diet.
🎯 Why Use a Macro Split Calculator?
Most people guess their macros — or follow a random diet plan they found on social media.
But this tool gives you personalized results based on:
- Your calorie goal
- Your fitness objective (fat loss, maintenance, or muscle gain)
- The macro split strategy you prefer (e.g., balanced, low-carb, high-protein)
No spreadsheets, no math — just smart nutrition made simple.

| Muscle Gain | 30% | 50% | 20% |
| Low-Carb | 40% | 20% | 40% |
You’ll see your daily grams of each macro, based on the percentage split and your calorie target.
