Protein powder cost per gram calculator
Turn a protein or collagen label into cost per gram and cost per 25 grams.
Enter the values above to see the decision math.
For collagen, compare cost per useful collagen grams separately from complete protein value.
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.
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.
