Calculate ingredient cost from actual purchasing data

Shrimp, chicken, and apple tart have different cost drivers. A useful calculation requires current supplier prices and the correct unit basis. The recipe data does not contain verified current restaurant purchasing prices, so it cannot promise a fixed margin.

What matters in the kitchen

Match each purchasing line to the product actually used. Keep package weight, price basis, gross quantity, and usable yield separate. A lower price per pound may still produce a different cost per serving when the cut or yield changes. Garnish, sauce, and small ingredients belong in the record too.

Putting it into practice

Attach the calculation to a recipe version and date so price or product changes can be reviewed selectively. Labor, energy, packaging, and other operating costs are additional items. Ingredient cost alone is neither a complete selling price nor a guarantee of profitability.
