Target costing is a cost management tool used to reduce the overall cost of a product over its lifecycle. It was developed by Toyota in 1965 in response to rising costs and fewer opportunities for cost reductions late in development. The target costing process involves determining a target price based on market research, then working backwards to establish a target cost per unit by determining required profit levels. The goal is to motivate cross-functional teams to innovatively design products that meet cost targets and ensure planned profit levels.
