IMPORTANT NOTES: OVERHEAD ALLOCATION* *scale 10 to 15...100% chances
*US CMA PART 1 Cost Management*
_By Prof. Mahaley | Gmsisuccess Mumbai_
Overhead = All indirect costs. You CANNOT trace them directly to 1 product. So we *ALLOCATE* them.
*1. THE 4-STEP OVERHEAD ALLOCATION PROCESS*
This is the foundation for CMA. 1-2 MCQs direct from this every exam.
**Step** **What We Do** **Example**
**1. Accumulate OH** Group all Mfg OH into Cost Pools Setup OH Pool, Inspection OH Pool
**2. Choose Allocation Base** Find Cost Driver that causes the OH Machine Hours, DL Hours, No. of Setups
**3. Calculate OH Rate** `OH Rate = Total OH in Pool / Total Driver Units` $50,000 / 10,000 MH = $5/MH
**4. Apply OH** `Applied OH = OH Rate x Actual Driver Used by Job` Job A used 200 MH x $5 = $1,000
---
*2. 3 MAIN METHODS OF OVERHEAD ALLOCATION*
*A. PLANTWIDE OVERHEAD RATE METHOD*
*Concept*: 1 Rate for whole factory. Simple but least accurate.
*Formula*: `Plantwide Rate = Total Mfg OH / Total Allocation Base`
*Base Used*: Usually DL Hours or Machine Hours
*Use When*: Only 1 product or all products use resources equally
*CMA Trap*: Causes *Cross-Cost Subsidization*. Overcosts simple products, Undercosts complex products.
*B. DEPARTMENTAL OVERHEAD RATE METHOD*
*Concept*: Different rate for each department. More accurate than plantwide.
*Formula*: `Dept Rate = Total OH of Dept / Total Driver of Dept`
*Base Used*: Machining Dept = Machine Hours. Assembly Dept = DL Hours
*Use When*: Departments are very different in technology
*CMA Favorite*: 2-Stage Allocation
Stage 1: Allocate Service Dept OH to Production Depts
Stage 2: Calculate rate for each Production Dept
*C. ACTIVITY BASED COSTING - ABC*
*Concept*: Most accurate. Allocate based on activities that actually cause cost.
*Formula*: `Activity Rate = Cost Pool / Total Cost Driver`
*Base Used*: Multiple Cost Drivers. Ex: No. of Setups, No. of Inspections, No. of POs
*Use When*: High OH, Diverse products, Complex operations
*Benefits*: Reduces Overcosting/Undercosting. Better product pricing decisions
*CMA Must Know*: ABC is NOT for external reporting. Used for internal decisions only.
---
*3. CHOOSING THE ALLOCATION BASE - COST DRIVER*
Good driver has *Cause & Effect* relationship.
*Common Drivers:*
1. *Volume Based*: DL Hours, Machine Hours, Units Produced - for traditional methods
2. *Activity Based*: No. of Setups, No. of Inspections, Square Feet - for ABC
*Rule for CMA*: If OH is related to machine use → Use Machine Hours. If related to labor → Use DL Hours.
---
*4. OVERAPPLIED vs UNDERAPPLIED OVERHEAD*
This comes EVERY exam. 2-3 MCQs.
`Applied OH = OH Rate x Actual Driver Used`
`Actual OH = Real OH Incurred`
**Case** **Meaning** **Balance** **3 Ways to Close**
**Overapplied** Applied > Actual Credit 1. Prorate to WIP, FG, COGS 2. Write-off to COGS 3. Carry forward
**Underapplied** Applied < Actual Debit Same 3 ways
*CMA Exam Rule*: If amount is *IMMATERIAL* → Close to COGS directly
*Journal*: Dr. Mfg OH Cr. COGS for Overapplied. Reverse for Underapplied
---
*5. ALLOCATION OF SERVICE DEPT COSTS*
Service Depts don't make product. Ex: Maintenance, HR, QC
*3 Methods - In order of Accuracy:*
1. *Direct Method*: Allocate Service Dept to Production Depts only. Ignore service-to-service. _Easiest_
2. *Step/Sequential Method*: Allocate in order. Once allocated, that dept gets no cost back. _Medium_
3. *Reciprocal Method*: Most accurate. Considers service-to-service. Uses equations/matrix. _Hardest - CMA rarely asks calculation_
*6. KEY CMA CONCEPTS & TRICKS*
1. *Overcosting vs Undercosting*
Plantwide rate → Complex products are *Undercosted*, Simple products are *Overcosted*. ABC fixes this.
2. *Mfg OH vs Non-Mfg OH*
*Mfg OH* = Inventoriable. Goes to Inventory first. Ex: Factory Rent
*Non-Mfg OH* = Period Cost. Expensed immediately. Ex: Sales Manager Salary
3. *Capacity Levels for OH Rate*
`OH Rate = Budgeted OH / Capacity Level`
*Theoretical*: 100% capacity. No downtime
*Practical*: Max minus normal downtime. _Most used for budgeting_
*Normal*: Average over long term. _Used for product costing_
*Expected*: This year's budget.
Using higher capacity → Lower OH Rate per unit
4. *Proration Formula*
`Prorated Amount = Total Variance x (Account Balance / Total of WIP+FG+COGS)`
---
*7. QUICK FORMULAS TO MEMORIZE*
1. `Applied OH = Predetermined OH Rate x Actual Activity`
2. `Predetermined OH Rate = Budgeted OH / Budgeted Activity`
3. `COGM = Beg WIP + DM + DL + Applied OH - End WIP`
4. `Underapplied OH = Actual OH - Applied OH`
---
*CMA EXAM PATTERN*
1. *MCQ*: 50% on ABC vs Traditional. "Which product is overcosted?"
2. *Problem*: Calculate Departmental OH Rate + Apply to Job + Close Underapplied OH
3. *Essay*: Explain why ABC is better + limitations
*Golden Rule*: More cost pools + More cost drivers = More accurate = Less cross-subsidization
*Best Wishes 🍀*

*1-PAGE CHEAT SHEET: OVERHEAD ALLOCATION*
*US CMA PART 1* | _By Prof. Mahaley | Gmsisuccess Mumbai_
*A. 4-STEP PROCESS*
1. *Accumulate* OH into Cost Pools
2. *Select* Allocation Base / Cost Driver
3. *Calculate* Rate = `Budgeted OH / Budgeted Driver`
4. *Apply* OH = `Rate x Actual Driver Used`
*B. 3 METHODS*
**Method** **# of Rates** **Accuracy** **Best For** **CMA Key Point**
**Plantwide** 1 for whole plant Low Single product, similar products Causes Cross-Cost Subsidization
**Departmental** 1 per dept Medium Different depts like Machining vs Assembly 2-Stage: Service→Production→Product
**ABC** Many Activity Rates High Multiple products, High OH, Complex Uses Multiple Drivers. Reduces Over/Undercosting
*C. OVERAPPLIED / UNDERAPPLIED*
`Applied OH = Rate x Actual Activity`
`Variance = Actual OH - Applied OH`
**Variance** **Meaning** **Treatment**
**Overapplied** Applied > Actual Credit Balance. Dr Mfg OH Cr COGS
**Underapplied** Applied < Actual Debit Balance. Dr COGS Cr Mfg OH
*Rule*: If *Immaterial* → Close to COGS. If *Material* → Prorate to WIP, FG, COGS
*D. KEY FORMULAS*
1. `Dept OH Rate = Total Dept OH / Total Dept Driver`
2. `Activity Rate ABC = Cost Pool / Total Cost Driver`
3. `Proration = Total Variance x (Account Balance / Total WIP+FG+COGS)`
4. `COGM = Beg WIP + DM + DL + Applied OH - End WIP`
*E. CAPACITY LEVELS*
*Theoretical* > *Practical* > *Normal* > *Expected*
Higher Capacity used = Lower OH Rate per unit
