Profit Margin Calculator

A simple, user-friendly calculator for retail stores (convenience stores, minimarts, gas stations and other retail outlets) to calculate the each item's cost including base price and other associated ancillary costs (shipping and handling, special taxes, like tobacco taxes - excluding sales taxes, admin fees, commissions), and then let the owner adjust the selling price after adding the desired percentage of profit margin on the item. Finally it provides the owner with the selling price and the net profit on that item and the owner can reset or readjust the selling price accordingly.
