Cigar Box CB5 provides a simple, one spreadsheet solution to calculate prices and margins for a single product in a supply chain. This example is taken from Afghan carpet production, exported through Pakistan. It gives margin information from the wool washers, spinners, weavers (usually women and children), traders, cutters/washers and the wholesalers who export the carpets.
CB5 also calculates who makes a profit and who does not earn enough to make a living. The system of Living Wage, used in the Fair Trade business, is used to compare earnings with the need of a person to make a living.
