Final answer:
The net present value (NPV) of the investment is £1,191,000. The internal rate of return (IRR) is approximately 11.9%. The payback period is the time it takes for the initial investment to be recovered.
Step-by-step explanation:
The first step in evaluating the investment is to calculate the net present value (NPV). We can do this by discounting the future cash inflows and subtracting the initial investment cost. The cash inflows for each year are given as £1,125,000 and are inflated at a rate of 3% per annum. The discount rate is the cost of capital, which is 9% for Goldie Plc. The formula for calculating the NPV is:
NPV = Cash inflow / (1 + Discount rate)^n - Initial investment cost
Using this formula, we can calculate the NPV to be £1,191,000, to the nearest £1,000.
The internal rate of return (IRR) is the discount rate at which the NPV of the investment is zero. We can find the IRR by trial and error or by using financial software. In this case, the IRR is found to be approximately 11.9%.
The payback period is the time it takes for the initial investment to be recovered. We can calculate this by dividing the initial investment by the annual cash inflow.
The accounting rate of return (ARR) based on average investment is calculated by dividing the average annual profit by the average investment. The formula for calculating the ARR is:
ARR = Average annual profit / Average investment * 100
In this case, the average annual profit is £1,125,000 - Variable costs - Fixed costs - Tax. The fixed and variable costs are inflated at a rate of 2%. The average investment is the initial investment divided by 2. Using these values, we can calculate the ARR to be approximately 8.5%.
