## Total Market Potential

Total market potential is the maximum amount of sales that might be available to all the firms in an industry during a given period under a given level of industry marketing effort and given environmental conditions. A common way to estimate total market potential is as follows: Estimate the potential number of buyers times the average quantity purchased by a buyer times the price.

A variation on this method is the chain-ratio method. It involves multiplying a base number by several adjusting percentages. Suppose a brewery is interested in estimating the market potential for a new light beer. An estimate can be made by the following calculation:34

Demand for the new light beer = Population x personal discretionary income per capita x average percentage of discretionary income spent on food x average percentage of amount spent on food that is spent on beverages x average percentage of amount spent on beverages that is spent on alcoholic beverages x average percentage of amount spent on alcoholic beverages that is spent on beer x expected percentage of amount spent on beer that will be spent on light beer
