Let’s calculate the marginal cost at different capacities and then determine the estimated profit.
Given Data:
- Selling Price at 50% capacity = Rs. 200 per unit
- Cost per unit at 50% capacity = Rs. 180
- Material Cost at 50% capacity = Rs. 100
- Wages at 50% capacity = Rs. 30
- Factory Overheads at 50% capacity = Rs. 30 (40% fixed)
- Administrative Overheads at 50% capacity = Rs. 20 (50% fixed)
1. At 50% Capacity:
[ \text{Variable Cost per unit} = \text{Material Cost} + \text{Wages} + \text{Variable portion of Factory Overheads} + \text{Variable portion of Admin Overheads} ]
[ \text{Fixed Cost per unit} = \text{Fixed portion of Factory Overheads} + \text{Fixed portion of Admin Overheads} ]
[ \text{Total Cost per unit} = \text{Variable Cost per unit} + \text{Fixed Cost per unit} ]
[ \text{Contribution per unit} = \text{Selling Price} – \text{Total Cost per unit} ]
2. At 60% Capacity:
Increase in raw material cost by 2%, decrease in selling price by 2%.
[ \text{Variable Cost per unit (60%)} = \text{Material Cost (60%)} + \text{Wages} + \text{Variable portion of Factory Overheads} + \text{Variable portion of Admin Overheads} ]
[ \text{Fixed Cost per unit (60%)} = \text{Fixed portion of Factory Overheads} + \text{Fixed portion of Admin Overheads} ]
[ \text{Total Cost per unit (60%)} = \text{Variable Cost per unit (60%)} + \text{Fixed Cost per unit (60%)} ]
[ \text{Contribution per unit (60%)} = \text{Selling Price (60%)} – \text{Total Cost per unit (60%)} ]
3. At 80% Capacity:
Increase in raw material cost by 5%, decrease in selling price by 5%.
[ \text{Variable Cost per unit (80%)} = \text{Material Cost (80%)} + \text{Wages} + \text{Variable portion of Factory Overheads} + \text{Variable portion of Admin Overheads} ]
[ \text{Fixed Cost per unit (80%)} = \text{Fixed portion of Factory Overheads} + \text{Fixed portion of Admin Overheads} ]
[ \text{Total Cost per unit (80%)} = \text{Variable Cost per unit (80%)} + \text{Fixed Cost per unit (80%)} ]
[ \text{Contribution per unit (80%)} = \text{Selling Price (80%)} – \text{Total Cost per unit (80%)} ]
Now, calculate the estimated profit at 60% and 80% capacities using the contribution per unit figures. The profit is calculated as follows:
[ \text{Estimated Profit} = (\text{Contribution per unit} \times \text{Number of Units Produced}) – \text{Fixed Costs} ]
Ensure that all calculations are based on consistent units (e.g., lakhs or rupees).
