Investment goods or Capital goods are physical assets that a company uses in the manufacturing process to create products and services that consumers will use in the future. Buildings, machinery, equipment, vehicles, and tools are examples of capital goods. Investment goods are not finished goods; rather, they are used in the production of finished goods.
Investment goods, such as machinery and manufacturing equipment, are not always fixed assets. The industrial electronics industry manufactures a wide range of capital goods. Small wire harness assemblies to air-purifying respirators and high-resolution digital imaging systems are examples. Investment goods are also manufactured for service industries.
