Installed base

Installed base of a product is the number of units that are currently in use by customers. It provides a measurement of a company's existing customer base and the extent of their investment in a particular product or technology. In contrast to market share, which only reflects sales over a specific period and relative to the total market, the installed base represents the number of units currently in use. This information can be used to evaluate a company's customer base, investment, and market position.

The installed base plays a significant role in various industries, including computing, automotive, medical devices, and home appliances. It can impact the level of support, availability of replacement parts, and other factors. Some companies that have leveraged their installed base include Apple, Microsoft, Nintendo in the computing industry, and Tesla in the automotive industry.

Significance of Installed Base
The installed base of company's products represents a valuable customer base that is already using their products, services or systems. This provides companies with an opportunity to upsell and cross-sell their products to existing customers, as well as to use the information about their customer base to inform future product development and marketing efforts. Companies can use their installed base to determine the average lifespan of their products, which can inform product development and planning, as well as to assess their market position and to track the success of their product over time.
