To calculate the NPV of the project, we need to find the cash inflows and outflows for each year and discount them back to their present value using the corporate discount rate of 15%.
Year 0:
Initial investment = 1,500 million VND
Working capital = -300 million VND
Year 1:
Revenue = 860 million VND
Variable costs = -344 million VND (40% of net sales)
Fixed costs = -250 million VND
Depreciation = -250 million VND (1,500 million VND / 6)
Operating income before taxes = 16 million VND (860 - 344 - 250 - 250)
Taxes = -3.2 million VND (20% of operating income before taxes)
Operating income after taxes = 12.8 million VND (16 - 3.2)
Add back depreciation = 250 million VND
Net cash flow = 262.8 million VND
Discounted cash flow = 228 million VND (262.8 / 1.15)
Year 2:
Revenue = 920 million VND
Variable costs = -368 million VND (40% of net sales)
Fixed costs = -250 million VND
Depreciation = -250 million VND (1,500 million VND / 6)
Operating income before taxes = 52 million VND (920 - 368 - 250 - 250)
Taxes = -10.4 million VND (20% of operating income before taxes)
Operating income after taxes = 41.6 million VND (52 - 10.4)
Add back depreciation = 250 million VND
Net cash flow = 291.6 million VND
Discounted cash flow = 231.9 million VND (291.6 / 1.15^2)
Year 3:
Revenue = 1,050 million VND
Variable costs = -420 million VND (40% of net sales)
Fixed costs = -250 million VND
Depreciation = -250 million VND (1,500 million VND / 6)
Operating income before taxes = 130 million VND (1,050 - 420 - 250 - 250)
Taxes = -26 million VND (20% of operating income before taxes)
Operating income after taxes = 104 million VND (130 - 26)
Add back depreciation = 250 million VND
Net cash flow = 354 million VND
Discounted cash flow = 255.3 million VND (354 / 1.15^3)
Year 4:
Revenue = 1,200 million VND
Variable costs = -480 million VND (40% of net sales)
Fixed costs = -250 million VND
Depreciation = -250 million VND (1,500 million VND / 6)
Operating income before taxes = 220 million VND (1,200 - 480 - 250 - 250)
Taxes = -44 million VND (20% of operating income before taxes)
Operating income after taxes = 176 million VND (220 - 44)
Add back depreciation = 250 million VND
Net cash flow = 426 million VND
Discounted cash flow = 286.6 million VND (426 / 1.15^4)
Year 5:
Revenue = 880 million VND
Variable costs = -352 million VND (40% of net sales)
Fixed costs = -250 million VND
Depreciation = -250 million VND (1,500 million VND / 6)
Operating income before taxes = 28 million VND
