Cost Accounting
calculation of the cost of manufactured inventory
Prime Costs
DM + DL
Conversion Costs
DL + OH
Raw Material vs Direct Materials
Direct Materials are the materials physically included in the FINAL manufactured product
Normal Cost Systems
2. Manufacturing OH is based on standard
Applied Overhead Formula
(Estimated OH Costs / Estimated Direct Labor Costs or Hours) * Actual Production
Predetermined OH Rate
Estimated OH Costs / Estimated Direct Labor Costs or Hours

How do Variable & Absorption costing methods of accounting differ for fixed mfg overhead differ?
Variable: Fixed MFG OH is expensed in the period incurred
Absorption: Fixed MFG OH is treated as a product cost (inventoried) and expensed when sold
Operating Income under Absorption Costing
Sales
- Cost of Sales
= GROSS PROFIT
Operating Income under Direct Costing (Variable Costing)
Sales
- Variable Costs
= CONTRIBUTION MARGIN
PSA Mnemonic
Production>Sales —- Absorption
If ending inventory is greater than beginning inventory, then Absorption Operating Income is greater than Variable Operating Income
Variable vs Absorption
Difference in Operating Income Calculation
Fixed MFG OH per unit * Change in # of Units in Inventory
Cost-Volume-Profit
Breakeven in Units Formula
[Total Fixed Costs – Profit (loss)] / (SP per unit – VC per unit)
*SP-VC=CM per unit
Breakeven in Sales Dollars
[Total Fixed Costs – Profit (loss)] / (CM per unit / Sales Price per unit)
*CM/SP = CM Ratio = (SP-VC)/(SP)
What is the operating profit at breakeven point?
Operating Profit = $0
Desired Profit (Cost Volume Profit)
Add DESIRED PROFIT to Total Fixed Costs Numerator
(Total Fixed Costs + Desired Profit) / CM Per Unit
Desired Return on Sales (Cost Volume Profit)
(Total Fixed Costs + Desired Profit x Return on Sales%) / CM RATIO = Sales
Explain Margin of Safety
Margin of Safety in Dollars
Total Sales – Breakeven Sales
Margin of Safety Ratio
Margin of Sales in Dollars / Total Sales
