How It Works

How It Works

This calculator finds the percentage of your total daily calories that come from protein. Since each gram of protein provides 4 calories, we first convert protein grams into calories.

Then, we compare those protein calories to your total daily calories. The result shows what portion of your total energy intake comes from protein.

  • Each gram of protein provides 4 calories
  • Protein calories = protein grams × 4
  • Divide protein calories by total daily calories
  • Multiply by 100 to convert to a percentage

Understanding the Results

The final number shows what percentage of your daily calories comes from protein. For example, if the result is 25%, that means one-quarter of your daily calories are from protein.

Higher percentages mean more of your energy intake comes from protein, while lower percentages mean protein makes up a smaller part of your daily calories.

  • 20–30% is common in balanced diets
  • Higher percentages are typical in high-protein diets
  • Lower percentages may indicate more carbs or fats in the diet
  • The result helps you compare your intake to your nutrition goals
