解释:
老师好,请教下,如果用一种在实务中经常毛估估用的方法来计算,答案是不对,能不能帮忙讲下是哪里不对。
我的方法是:COGS 中占比4%的metal的成本增加了20%,那么总的COGS增加了4%*20%=0.8pct,那么gross profit margin 就下降了0.8pct。
请教下怎么去理解这样做是不对的呢?我错在了哪里呢?

NO.PZ201512300100000705 The sensitivity analysis consists of increase of 20% in the priof input thconstitutes 4% of cost of sales. Change in grossprofit margin because of thincrease is calculatethe change in cost of sales because of priincrease visales: = (Cost of sales × 0.04 × 0.2)/Sales = (105.38 × 0.04 × 0.2)/152.38 = 0.0055 为什么不是*1.2*(1-4%)
NO.PZ201512300100000705 老师好 为什么 这里分母不是乘以 1.2 而是乘以0.2 “(Cost of sales × 0.04 × 0.2)/Sales” 谢谢 , 讲义里 有总结过 increase xx from xx , 是 + x%; increase x%是指 G *(1+x%)。 题中”increase “ 该怎么理解 是和incease X% 的意思不同的,是吗?
NO.PZ201512300100000705 老师好,我把计算步骤列出来了,带一撇的是变化后的意思,谢谢老师。
NO.PZ201512300100000705 0.80 percentage points. 3.32 percentage points. A is correct. The sensitivity analysis consists of increase of 20% in the priof input thconstitutes 4% of cost of sales. Change in grossprofit margin because of thincrease is calculatethe change in cost of sales because of priincrease visales: = (Cost of sales × 0.04 × 0.2)/Sales = (105.38 × 0.04 × 0.2)/152.38 = 0.0055Profit margin的计算不是应该为SALES-COGS/SALES,而答案用COGS/SALES?
