The document provides an overview of manufacturing cost accounting concepts and calculations including job order costing, activity based costing, standard costs, and flexible budgets. It discusses calculating product costs, contribution margin, breakeven analysis, master budget components including direct materials budget, labor variances, and flexible budget performance reports. The key information covered relates to accounting for costs in a manufacturing environment.
2. Outline
Cost Terms, Concepts, and
Classifications
Job Order Costing
Cost Behavior
Cost – Volume – Profit
Activity Based Costing
Profit Planning
Standard Costs
Flexible Budgets and Overhead
3. Product Costs - A Closer
Look
Manufacturing Work
Raw Materials Costs In Process
Beginning raw Direct materials Beginning work in
materials inventory + Direct labor process inventory
+ Raw materials + Mfg. overhead + Total manufacturing
purchased = Total manufacturing costs
= Raw materials costs = Total work in
available for use process for the
in production period
Costs associated with the goods that – Ending work in
are completed during the period are process inventory
transferred to finished goods = Cost of goods
inventory. manufactured.
4. The Contribution Format
Total Unit
Sales Revenue $ 100,000 $ 50
Less: Variable costs 60,000 30
Contribution margin $ 40,000 $ 20
Less: Fixed costs 30,000
Net income $ 10,000
The contribution margin format emphasizes cost
behavior. Contribution margin covers fixed costs
and provides for income.
5. Calculating Breakeven in
Units
Here is the information from Wind
Bicycle Co.:
Total Per Unit Percent
Sales (500 bikes) $250,000 $ 500 100%
Less: variable expenses 150,000 300 60%
Contribution margin $100,000 $ 200 40%
Less: fixed expenses 80,000
Net income $ 20,000

10. Utilization of a Constrained
Resource
Let’s calculate the contribution margin
per unit of the scarce resource,
machine A1.
If there are no other considerations, the best
plan would be to produce to meet current
demand for Product 2 and then use remaining
capacity to make Product 1.
