Adding value refers to the difference between the price received for a finished good or service and the costs of inputs required to produce it. This value added can be calculated by taking revenue and subtracting total costs. A business owner created Tyrrell's Potato Chips by taking potatoes, a commodity, and adding value through distinctive flavors, packaging, and hand-fried preparation to create a premium branded product. Businesses can add value through branding, customer service, product features, efficiency, convenience, and unique selling points. Signs that a small business is adding value include strong gross profit margins, repeat business from satisfied customers, and good brand recognition.
