This document discusses methods for valuing goodwill of a business. It defines goodwill as the value of a firm's reputation that generates profits above normal levels, known as super profits. The value of goodwill is affected by factors like location, nature of business, management efficiency, time in business, market situation, and special advantages. Goodwill needs to be valued when partners join, retire, die, or the business dissolves. Common valuation methods include average profits, weighted average profits, super profits, capitalization of average/super profits, and present value of super profits. Illustrative examples are provided for each method.
