## Total Product:

Total product is a term used in economics. It tells analysts how much output (quantity) a company can produce when considering the law of diminishing marginal returns. It is calculated as follows:

Total Product = Average Product * Number of units of a factor employed

Total product is the overall quantity of output that a firm produces, usually specified in relation to a variable input. Total product is the starting point for the analysis of short-run production. It indicates how much output a firm can produce according to the law of diminishing marginal returns
