The business will qualify to receive a New Innovators Economic subsidy to the value of $20 000 from the municipality in Year 6.
Capital equipment is depreciated at 20% per annum on the straight-line method.
In both scenarios, assume a discount rate of 10%. Which option should you choose based on the NPV method ?
NPV = Cash Flow / (1 + i) ^ t - Initial Investment
Suggested Solution


Based on the NPV calculations, both product options show a positive NPV. Either product line can be accepted because both will generate positive value for the business.
Given that only one choice is available, it is better to choose Product B because it has a higher net present value.
