Costing Applications (Copy)

Absorption Costing:
- Allocates both fixed and variable costs to products.
- Full Costing: Includes both variable and fixed costs in the cost per unit.
- Formula for Unit Cost:
```
Total Cost per Unit = Variable Cost per Unit + (Fixed Manufacturing Costs / Total Units Produced)
```
- Example:
  - Variable Cost per Unit: $20
  - Fixed Manufacturing Costs: $100,000
  - Total Units Produced: 5,000 units
  - Absorption Cost per Unit:
```
Absorption Cost per Unit = 20 + (100,000 / 5,000) = 20 + 20 = 40
```
Marginal Costing:
- Assigns only variable costs to the product, treating fixed costs as period costs.
- Contribution Margin: The difference between sales price and variable cost.
- Formula for Contribution per Unit:
```
Contribution per Unit = Sales Price per Unit - Variable Cost per Unit
```
- Example:
  - Sales Price per Unit: $50
  - Variable Cost per Unit: $30
  - Contribution per Unit:
```
Contribution per Unit = 50 - 30 = 20
```

Unit Costing:
- Used for businesses that produce large volumes of identical products.
- Formula:
```
Unit Cost = Total Cost of Production / Total Units Produced
```
- Example:
  - Total Costs: $50,000
  - Total Units Produced: 1,000 units
  - Unit Cost:
```
Unit Cost = 50,000 / 1,000 = 50 per unit
```
Job Costing:
- Used for unique or customized products/services.
- Allocates direct materials, direct labor, and allocated overhead.
- Formula for Job Cost:
```
Job Cost = Direct Materials + Direct Labour + Allocated Overhead
```
- Example:
  - Direct Materials: $5,000
  - Direct Labour: $3,000
  - Allocated Overhead: $2,000
  - Total Job Cost:
```
Job Cost = 5,000 + 3,000 + 2,000 = 10,000
```
Batch Costing:
- Used when products are produced in batches.
- Formula for Cost per Batch:
```
Cost per Batch = Total Cost for the Batch / Number of Units in the Batch
```
- Example:
  - Total Cost for Batch: $2,000
  - Number of Units in Batch: 200
  - Cost per Unit:
```
Cost per Unit = 2,000 / 200 = 10 per unit
```

Feature	Absorption Costing	Marginal Costing
Fixed Costs	Allocated to products	Treated as period costs
Focus	Long-term pricing and profitability	Short-term decision-making
Costing Treatment	Full costing (variable + fixed)	Only variable costs are included
Suitability	Suitable for external reporting	Suitable for internal decision-making
Complexity	More complex due to fixed cost allocation	Simpler to use and interpret

Absorption Costing:
- Useful for long-term pricing decisions and profitability analysis.
- Required for external reporting to meet financial reporting standards.
Marginal Costing:
- Suitable for short-term pricing decisions, break-even analysis, and special order decisions.
- Helps in analyzing the contribution margin to cover fixed costs and generate profits.

Contribution Margin:

Contribution Margin = Sales Price per Unit - Variable Cost per Unit

Break-even Point:

Break-even Point = Fixed Costs / Contribution per Unit

Margin of Safety:

Margin of Safety = Actual Sales - Break-even Sales

Profitability Ratios (e.g., Net Profit Margin, Return on Investment):
- Net Profit Margin:
```
Net Profit Margin = (Net Profit / Sales Revenue) * 100
```

Absorption Costing:
- Can distort unit cost in fluctuating production volumes.
- Fixed costs may not be accurately represented when production is low.
Marginal Costing:
- Excludes fixed costs from product costs, which may lead to underpricing in some cases.
- Not suitable for long-term pricing strategies as it ignores fixed costs.

Absorption Costing: Full costing method, used for external reporting and long-term pricing decisions.
Marginal Costing: Focuses on variable costs, used for short-term decision-making and internal management.
Unit Costing, Job Costing, and Batch Costing: Applied based on production types and business needs.
