Example Calculation with the Macronutrient Calculator
Imagine your diet is 2,000 calories a day with a distribution of 40% carbohydrates, 30% proteins and 30% fats.
Total calories: 2,000
Protein percentage: 30%
Carbohydrate percentage: 40%
Fat percentage: 30%
📐 Applied formulas:
- Protein = (30% of 2,000) / 4 = 150 g
- Carbohydrates = (40% of 2,000) / 4 = 200 g
- Fats = (30% of 2,000) / 9 = 66.67 g
📊 Result: 150 g of protein, 200 g of carbohydrates, 66.67 g of fat daily
This means you can easily structure your meals based on these values.

How Does Our Macronutrient Calculator Work?
Our calculator follows a simple three-step process:
1️⃣ Data Entry
Total calories 🔥 They are the basis for calculating macronutrient distribution.
Protein Percentage 💪 Defines your muscle building and repair needs.
Carbohydrate Percentage 🍞 Determines your daily available energy.
Fat percentage 🥑 Provides hormonal functions and nutrient absorption.
Why is it important?
Being clear about the exact grams of macros prevents dietary mistakes and accelerates your physical or health results.
2️⃣ Automatic Calculation
We use these standard formulas:
📐
- Protein = (% cal / 100 × total cal) / 4
- Carbohydrates = (% cal / 100 × total cal) / 4
- Fats = (% cal / 100 × total cal) / 9
This gives you the amount of macronutrients in grams to follow a balanced diet.
3️⃣ Results and Recommendations
🔹 If the result fits your goals, maintain your distribution and measure weekly results.
🔹 If you need to improve your performance or health, adjust the percentages based on your activity or professional advice.
