Wardrobe Costing
1. **Problem Statement:** Prepare the Actual Statement of Comprehensive Income for Good-Quality-Wardrobes for the year ended 31 December 2024 using direct costing principles, calculate over/under recovered fixed manufacturing overheads, prepare the journal entry, and differentiate costing systems.
2. **Calculate Raw Material Cost per Wardrobe:**
Melamine Board cost per wardrobe = R3750
Box of nails and handles = R200
Varnish Paint = R350
Total raw material cost = R3750 + R200 + R350 = R4300
3. **Calculate Labour Cost:**
- Employees: 4 employees, 40 hours/week, 52 weeks - 3 weeks leave = 49 weeks
- Normal hours per employee = 40 * 49 = 1960 hours
- Overtime hours per employee = 10
- Normal labour rate = R16/hour
- Overtime labour rate = 2 * 16 = R32/hour
- Labour cost per employee = (1960 * 16) + (10 * 32) = 31360 + 320 = R31680
- Total labour for 4 employees = 4 * 31680 = R126720
- Supervisor: 1 supervisor, same hours
- Normal hours = 1960, overtime = 10
- Supervisor rate = R21/hour, overtime = 2 * 21 = R42/hour
- Supervisor labour cost = (1960 * 21) + (10 * 42) = 41160 + 420 = R41580
- Total labour cost = 126720 + 41580 = R168300
- Labour cost per wardrobe = R168300 / 195 wardrobes = R862.05
4. **Manufacturing Overheads:**
- Variable electricity cost per wardrobe = R200
- Fixed depreciation per month = R5000
- Annual depreciation = 5000 * 12 = R60000
- Fixed overhead per wardrobe = R60000 / 195 = R307.69
5. **Calculate Variable Manufacturing Cost per Wardrobe:**
= Raw material + Labour + Variable overhead
= 4300 + 862.05 + 200 = R5362.05
6. **Calculate Contribution Margin:**
Selling price per wardrobe = R8500
Variable cost per wardrobe = R5362.05
Contribution margin per wardrobe = 8500 - 5362.05 = R3137.95
7. **Calculate Total Contribution Margin:**
Wardrobes sold = 200
Total contribution margin = 200 * 3137.95 = R627590
8. **Calculate Fixed Costs:**
- Fixed manufacturing overhead = R60000
- Administrative expenses = R3000 per month, 40% variable
Variable admin = 0.4 * 3000 = 1200 per month
Fixed admin = 3000 - 1200 = 1800 per month
Annual fixed admin = 1800 * 12 = R21600
- Advertising expenses = R1000 per month, 50% variable
Variable advertising = 0.5 * 1000 = 500 per month
Fixed advertising = 1000 - 500 = 500 per month
Annual fixed advertising = 500 * 12 = R6000
- Total fixed costs = 60000 + 21600 + 6000 = R87600
9. **Calculate Variable Expenses:**
- Variable admin = 1200 * 12 = R14400
- Variable advertising = 500 * 12 = R6000
- Total variable expenses = 14400 + 6000 = R20400
10. **Calculate Variable Cost of Goods Sold:**
- Opening inventory = 10 wardrobes at R60000 total = R6000 per wardrobe
- Manufactured = 195 wardrobes
- Sold = 200 wardrobes
- Closing inventory = 10 + 195 - 200 = 5 wardrobes
- Variable cost per wardrobe = R5362.05
- Closing inventory value = 5 * 5362.05 = R26810.25
- Variable cost of goods sold = (10 * 6000) + (195 * 5362.05) - 26810.25 = 60000 + 1045600 - 26810.25 = R1086789.75
11. **Prepare Statement of Comprehensive Income (Direct Costing):**
- Sales = 200 * 8500 = R1700000
- Variable cost of goods sold = R1086789.75
- Variable expenses = R20400
- Contribution margin = 1700000 - 1086789.75 - 20400 = R589810.25
- Fixed costs = R87600
- Net profit = 589810.25 - 87600 = R502210.25
12. **(b)(i) Calculate Over/Under Recovered Fixed Manufacturing Overheads:**
- Applied fixed overhead = R100000
- Actual fixed overhead = R60000
- Over recovered overhead = 100000 - 60000 = R40000
13. **(b)(ii) Journal Entry for Over Recovered Overhead:**
- Debit Manufacturing Overhead R40000
- Credit Cost of Goods Sold R40000
14. **(c) Differentiate Direct Costing and Absorption Costing:**
- Direct costing includes only variable manufacturing costs in product cost; fixed manufacturing overhead is treated as a period expense.
- Absorption costing includes both variable and fixed manufacturing overheads in product cost.
**Final answers:**
- Statement of Comprehensive Income net profit = R502210.25
- Over recovered fixed overhead = R40000
- Journal entry: Debit Manufacturing Overhead R40000, Credit Cost of Goods Sold R40000
- Difference: Direct costing treats fixed overhead as period cost; absorption costing includes it in product cost.
