Calories Per 100g Protein
This measures protein purity. Pure protein contains 400 calories per 100g. Anything above that indicates additional calories from fats, carbs, or fillers. Lower is generally better if you're maximizing protein intake while controlling calories.

Frequently Asked Questions
How do I calculate price per 100g protein?
Use this formula: (Container price ÷ total protein grams) × 100. First calculate total protein by multiplying protein per serving by servings per container. Then divide the price by that number and multiply by 100.
What is a good price per 100g protein benchmark?
Under $6/100g is good value, under $5.50/100g is excellent. Between $6-8/100g is average. Over $9/100g is poor value unless you have specific dietary requirements like vegan protein.
Why does serving size matter for protein value?
Brands choose serving sizes arbitrarily. One brand might use a 20g scoop while another uses 35g—making the 'per serving' comparison meaningless. Price per 100g protein standardizes this across all products.
Does protein calculator work for plant-based protein?
Yes, the same calculation applies to all protein types. Plant proteins typically cost $2-4 more per 100g than whey due to more expensive raw materials and processing.
What about calories per 100g protein?
That's a separate metric measuring protein purity. Pure protein is 400 calories per 100g—anything above that comes from fats and carbs. Calculate it: (calories per serving ÷ protein per serving) × 100.
