Abs tract: This paper ananlyses the enterprise earnings uncertainty in three differenctways, and discovers
that themain factors of influencing the enterprise earningsuncertainty are the volume of sales, the standard devia-
tion coefficient of the sales volume, the period cost, the unit contributionmargin and the bond interest. When the
enterprisehas earned surplus, the good sales stale, the lower break- even point and bond interest can reduce the
enterprise earningsuncertainty.
K ey words: volume of sales; earnings before interest and tax; earnings per share; standard deviation coeff-i
