Calculation in kind or calculation in-natura is a way of valuating resources and a system of accounting that uses disaggregated physical magnitudes as opposed to a common unit of calculation. As the basis for a socialist economy, it was proposed to replace money and financial calculation. In an in-kind economy, products are produced for their use values (their utility) and accounted in physical terms. By contrast, in money-based economies, commodities are produced for their exchange value and accounted in monetary terms.
Calculation in kind would quantify the utility of an object directly without recourse to a general unit of calculation. This differs from other proposed methods of socialist calculation, such as Taylor-Lange accounting prices, and the use of labor time as a measure of cost.
