今天帮主邀请来Yvonne老师为大家讲解Absorption costing和Marginal costing的区别,大家仔细听讲~
今天来总结一下Management Accounting里面的一大重难点,吸收成本法(Absorption costing)和边际成本法(Marginal costing)两者之间的主要区别和联系。

01利润计算方法
文字解释:
①COS: 按销量计算,卖掉多少减多少。
吸收成本法下计入产品成本的只有total production cost(fixed production overhead & variable production overhead),当期销售出去的存货成本结转到利润表,即total production cost of sales;
边际成本法下计入产品成本的只有total variable cost(variable production overhead & variable non-production overhead),当期销售出去的存货成本结转到利润表,即total variable cost of sales。
②Under/over absorption:吸收成本法特有的,边际成本法不存在OAR和Under/over absorption。
涉及的计算公式:
Under/over absorption=Actual overhead-Absorbed overhead
Absorbed overhead=OAR*Actual activity level
OAR=Budget production overhead/Budget activity level
③Sales - COS:
吸收成本法下的主营业务收入-主营业务成本叫做Gross profit毛利润;
边际成本法下的主营业务收入-主营业务成本叫做Contribution贡献。
④Period cost:当期发生多少减多少。
吸收成本法下包含total non-production cost;
边际成本法下包含total fixed cost
⑤Valuation of closing inventory:Absorption costing > Marginal costing。
吸收成本法存货计价:Direct material+Direct labour+Variable production overhead+Fixedproduction overhead;
边际成本法存货计价:Direct material+Direct labour+Variable production overhead;
02标准成本法中的差异
①Cost variance---fixed production overhead variance
Absorption costing:
A.fixed production overhead total variance=under/over absorbed overhead
B.fixed production overhead expenditure variance=budgeted overhead-actual overhead
C.fixed production overhead volume variance=budgeted units*OAR-actual units*OAR
D.fixed production overhead volume efficiency variance=(budgeted hours at actual output-actual hours)*standard production overhead per hour
E.fixed production overhead variance=(budgeted hours-actual hours)*standard production overhead per hour
Marginal costing:(因为MC法下不存在OAR,所以对于fixed production overhead variance只有expenditure variance)
fixed production overhead expenditure variance=budgeted overhead-actual overhead
②Sales variance---sales volume variance
Absorption costing:sales volume profit variance=(budgeted units-actual units)*standardprofit per units
Marginal costing:sales volume profit variance=(budgeted units-actual units)*standardcontribution per units
③Operating statement
03联系
利润差公式:MC+OAR*(closing inventory-opening inventory)=AC
注:1.此公式的利润指两种成本核算方法下的净利润,不是contribution和gross profit的比较;
2. Closing inventory-Opening inventory=Production units-Sales units
3. 此公式可以用于求OAR=(AC-MC)/(closing inventory-opening inventory)
以上便是吸收成本法(Absorption costing)和边际成本法(Marginal costing)之间的主要差异和联系了,你记住了吗~
