As purchased to edible portion calculator.

Account for trim loss when finding the usable cost of an ingredient.

Last checked

Starting values are an illustrative example. Replace them with your own figures.

Cost per edible kg$5.00

How the calculation works

AP is the product as purchased. EP is the portion left after a specified preparation. Divide usable weight by purchased weight to measure yield. Apply a trim factor only once.

Formula: Purchase cost per kg ÷ (edible yield ÷ 100).

Worked example

The starting inputs are illustrative assumptions: Purchase cost per kg ($): 4; Edible yield (%): 80. They produce 5.00$. These inputs are editable and are not market prices or industry benchmarks.

Use the result

A cooked yield and a trimming yield describe different stages. Keep each stage visible and do not apply a whole-product yield to a pack already trimmed by the supplier.

Keep the period, unit and currency consistent across the inputs. A calculator cannot identify a missing cost from the figures you provide. Retain an invoice or stock-count record for the inputs, and use the result as a check on your operating decision.
