Price-Per-Nutrient Food Value Finder

Enter the package price, package size, and the nutrient amount (e.g., grams protein) per serving. The calculator estimates the nutrient total in the whole package, then computes price per nutrient (e.g., dollars per gram of protein) and also nutrient per dollar (e.g., grams of protein per dollar). It ranks foods so the best value is the lowest price-per-nutrient for your selected metric.

The “best value” depends entirely on the nutrient you choose—calories aren’t the same as protein, and fiber isn’t the same as fat. Label values are treated as uniform across the package, so differences in serving size accuracy, cooking loss, or portion variability aren’t modeled. If a product has near-zero amounts of the selected nutrient, it may be flagged as not comparable.

Make sure package size and nutrient units match what you intended (e.g., don’t enter calories as grams). Package price must be greater than 0 and package size must be greater than 0; otherwise the per-nutrient math can’t be computed. Also remember this tool compares value by the selected nutrient only—it won’t assess overall diet quality, micronutrients, or satiety.

If the selected nutrient is 0, the calculator avoids divide-by-zero and marks the result as not comparable or very poor value. Very small nutrient amounts can produce extreme “price per nutrient” numbers—interpret these as “not economical” rather than precise nutrition economics. Large package sizes are fine as long as the package price and nutrient inputs are consistent and correctly scaled.
