Protein Value Calculator
A low package price is not always a low price per usable serving. Compare foods on one transparent metric, then consider the rest of the meal.
Compare protein value
Enter package price, servings per package, and protein per serving for two foods. The tool compares cost per 25 g protein and shows the limits of that comparison.
—Food A per 25 g protein
—Food B per 25 g protein
Price is not nutritional quality
This calculator answers one narrow question: cost per 25 grams of listed protein. It does not rank foods overall. Beans may contribute fiber; dairy may contribute calcium; fish may contribute omega-3 fats; and preparation time or waste may decide what is actually affordable.
