Of course, you also can have a try the method that uses from above to below, search the market total scale that sees your product to have to the net first how old, your set target, with year be an unit and need not be a month, with take division, advanced even algebra, target of the first year is occupational the market share of 15%, set breaks up every year one time (it is easy to such comparison, excel is pulled came out), the 2nd year 30%, the 3rd year 45%, the 4th year 60%......

当然，你也可以试试看用自上而下的方法，先到网上搜索一下看你产品的市场总规模有多大，你设定目标，以年为单位而不必是月，用乘除法，甚至高等代数，第一年的目标是占领15%的市场份额，设定每年翻一番(这样比较容易，Excel一拉就出来了)，第二年30%，第三年45%，第四年60%。。。。。。
