When the expenditures or value of production of an item is divided by the quantity, the result is known as a unit value.

The unit value of a set of homogeneous products is the total value of the purchases / sales divided by the sum of the quantities. It is therefore a quantity-weighted average of the different prices at which the product is purchased / sold. Unit values may change over time as a result of a change in the mix of the products sold at different prices, even if the prices do not change.
