Protein Powder Cost per Gram Calculator
Compare protein powders by cost per serving, per gram of protein and per 25 g of protein. Enter protein grams, not the weight of the scoop.
Quick answer
Cost per protein gram = container price / (servings x protein grams per serving). A $40 container with 20 servings and 25 g protein per serving costs $0.08 per protein gram, or $2 per 25 g.
Enter protein grams from Nutrition Facts or Supplement Facts. A 30 g scoop does not necessarily contain 30 g of protein.
How to use the number
Cost per gram is useful, but it is not the whole product decision. Protein type, amino acid profile, sweeteners, third-party testing, serving size realism, and GI tolerance can matter as much as price.
Compare the supplement calculation with food-first breakfast protein examples before deciding whether powder is needed.
For collagen, compare collagen grams against collagen goals. Do not treat collagen as equivalent to a complete protein powder just because both labels list grams.
How this tool works
Use the serving count and the protein line from the same flavor and container size. Divide the price by servings for cost per serving, then divide by protein grams for cost per gram. Multiply that result by 25 for a standardized price comparison.
A common mix-up: a 30 g scoop containing 22 g protein must be entered as 22, not 30. Price, taste, allergens and how a product fits your diet still matter.
The 25 g amount is not a daily intake recommendation. Collagen and complete proteins do not have the same amino acid profile; see NIH ODS on protein and exercise.
