There exist a number of commercially-available cost modeling tools to assist the NASA cost estimator develop realistic cost estimates. The NASA estimates are primarily based on NAFCOM (NASA-Air Force Cost Model). NAFCOM is an automated parametric cost estimating tool that uses historical space data to predict the development and production costs of new space programs. It uses parametric relationships to estimate subsystem- and component-level costs for aerospace hardware‚ including Earth-orbiting
