How to use this calculator

Enter your total daily calorie intake in the calculator
Click "Calculate" to see your recommended macronutrient breakdown
Review the results and adjust your diet accordingly

The calculator will show you how many grams of protein, carbohydrates, and fat you should consume each day based on your calorie intake.

Formula used

Protein: (Total Calories × 0.10) ÷ 4

Carbohydrates: (Total Calories × 0.59) ÷ 4

Fat: (Total Calories × 0.15) ÷ 9

Where:

4 is the number of calories per gram of protein and carbohydrates
9 is the number of calories per gram of fat

Worked example

If you consume 2,000 calories per day:

Protein: (2,000 × 0.10) ÷ 4 = 50 grams
Carbohydrates: (2,000 × 0.59) ÷ 4 = 295 grams
Fat: (2,000 × 0.15) ÷ 9 ≈ 33 grams

This gives you a daily macronutrient breakdown of 50g protein, 295g carbohydrates, and 33g fat.
