For example, a consumer buys a PC from Samsung at $2,500, which indicates the revenue supply chain achieved. All the stages incur costs to ensure the efficient transfer of funds, information, storage of the product and transportation to the final consumer. The difference between revenue from selling the PC and the supply chain cost represents the supply chain surplus or supply chain profitability. Supply chain surplus is the total profit shared by all the stages and intermediaries. The greater the supply chain surplus, the more successful the supply chain. The success of supply chain calculated by its overall surplus not by the profit at each part of stages.
