There are many methods for calculating market size but experience shows that, firstly, a fairly narrow number of methods are used in practice, and secondly, there is no universal method of calculating it for any market or segment - each field needs an individual approach. It should also be noted that market size is a calculated or predicted value and therefore may have inaccuracies. This value is calculated on the basis of certain assumptions and generalizations of various facts that took place in the past and not in the future. At the same time, the calculation of the market displays figures which are close to reality and which can and should be used in making strategic decisions.
