Cost per active gram calculator
Normalize comparable assay-based prices and calculate ingredient mass for a formulation target.
Illustrative inputs, not supplier prices. Replace every assumption with your own quote. All costs are USD.
Cost per gram of the specified active
$0.50
Ingredient mass per unit: 200 mg · Ingredient cost per unit: $0.01
How to compare active-ingredient cost
Active grams per kg = 1,000 × assay% ÷ 100. Cost per active gram = price per kg ÷ active grams. Ingredient mg per unit = target mg ÷ (assay% ÷ 100).
Use a comparable assay percentage by mass for the same named analyte. Chromatographic area percent, dry-basis results, ester content, and a different marker total may need technical review before use here. The formulation target is your own input, not a recommended dose. The calculation excludes manufacturing loss, overage, excipients, packaging, and processing costs.
Example: a $50/kg ingredient at 10% comparable active content supplies 100 g of that active per kg, costing $0.50 per active gram. A user-entered 20 mg target requires 200 mg of this ingredient and costs $0.01 before other costs.
Use the ingredient sourcing guides to define comparable articles and the buyer document checklist to identify missing information.
