Answer:
1)
Payback period = Initial investment / Annul cash flow
Payback period = 1,880,000 / 480,000
Payback period = 3.92 years
2)
Accounting rate of return = Average cash flow / ( initial investment - book value) / 2
Accounting rate of return = 480,000 / ( 1,880,000 - 0)/2
Accounting rate of return = 0.5106 or 51.06%
3)
NPV = Present value of cash inflows - present value of cash outflows
NPV = 480,000 * 4.968 - 1,880,000
NPV = $504,640
4)
IRR is the rate of return that makes NPV equal to 0
NPV = Annuity * [ 1 - 1 / ( 1 + R)n] / R - initial investment
NPV = 480,000 * [ 1 - 1 / ( 1 + R)8] / R - 1,880,000
Using trial and error method, i.e, after using various values for R, let's try R as 19.32%
NPV = 480,000 * [ 1 - 1 / ( 1 + 0.1932)8] / 0.1932 - 1,880,000
NPV = 0
Therefore, IRR is 19.32%
Splash world should invest in the project as it has a positive NPV and and IRR greater than cost of capital
