Abstract: The present method and system relates to processor-based valuations of an entity, such as a business, comprising a best value mode for iteratively generating optimized input elements and calculating an output data set from the optimized input elements that meet the conditions of the parties interested in the valuation, an interactive mode enabling a user to modify the input elements to determine how the modified elements affect the financial output of the valuation, and a module enabling the user to switch between the best value and interactive modes.
