Macros Split Calculator

Macros Split Calculator helps you determine your daily macronutrient intake (carbohydrates, proteins, and fats) based on your total daily calorie goal and desired percentage split. Enter your calories and macro percentages, then click “Calculate Macros” to see the grams needed for each macronutrient.

How to Use Macros Split Calculator:

1. Enter your total daily calorie goal in kilocalories (kcal).
2. Enter the desired percentage for carbohydrates, proteins, and fats (must sum to 100%).
3. Click “Calculate Macros” to see the grams and calories for each macronutrient.
4. Use “Share Result” or “Copy Result” to share or copy the output.

Calculation Details:

The calculator computes grams of each macronutrient using:

• Carbohydrates: \\(\text{Grams} = \frac{\text{Calories} \times \text{Carb \%}}{4}\\), (4 kcal/g)
• Proteins: \\(\text{Grams} = \frac{\text{Calories} \times \text{Protein \%}}{4}\\), (4 kcal/g)
• Fats: \\(\text{Grams} = \frac{\text{Calories} \times \text{Fat \%}}{9}\\), (9 kcal/g)
• Total Calories: \\(\text{Carb Grams} \times 4 + \text{Protein Grams} \times 4 + \text{Fat Grams} \times 9\\)

Note: Percentages must sum to 100%. Consult a nutritionist for personalized macro goals.

Important Notes:

• Caloric values are standard: 4 kcal/g for carbs and proteins, 9 kcal/g for fats.
• Macro needs vary based on activity level, goals (e.g., weight loss, muscle gain), and health conditions.
• Clipboard access requires HTTPS. If copying fails, try accessing over HTTPS or copy manually.
