Embodiments are directed toward unified modeling of technology towers. Template information that corresponds to a technology tower may be selected by a user such that the template information identifies cost items, cost pools, and cost drivers. Cost information corresponding to the cost items may be determined from a dataset and mapped to the cost pools based on the template information. Cost driver information for the cost drivers may be determined from the information that was included in the dataset. A technology tower may be generated based on the cost pools and the cost drivers such that the cost pools and cost drivers correspond to the cost items. The technology tower may be provided to an application for generating one or more financial models. Key performance indicators for cost items may be generated based on the cost pools and the cost drivers.
