Final answer:
To calculate the EAC for machine A, we need to find the present value of the cash flows associated with the machine over its useful life. The annual cash flow is calculated as the sales minus variable costs minus fixed costs. The present value is then divided by the annuity factor to find the EAC.
Step-by-step explanation:
To calculate the EAC (Equivalent Annual Cost) for machine A, we need to find the present value of the cash flows associated with the machine over its useful life. First, we calculate the annual cash flow, which is the sales minus variable costs minus fixed costs. Then, we calculate the present value of the cash flows using the required return rate as the discount rate. Finally, we divide the present value by the annuity factor to find the EAC.
The annual cash flow for machine A is calculated as follows:
Sales: $10 million
Variable costs: 31% of sales = 0.31 x $10 million = $3.1 million
Fixed costs: $1,960,702
Annual cash flow: $10 million - $3.1 million - $1,960,702 = $5,939,298
The present value of the annual cash flows is calculated using the formula:
Present value = Annual cash flow / ((1 + required return rate) ^ useful life)
Present value = $5,939,298 / ((1 + 0.07) ^ 6) = $4,525,709.79
Finally, we divide the present value by the annuity factor:
EAC = Present value / annuity factor
Annuity factor = ((1 - (1 / ((1 + required return rate) ^ useful life))) / required return rate)
Annuity factor = ((1 - (1 / ((1 + 0.07) ^ 6))) / 0.07) = 4.818769436
EAC = $4,525,709.79 / 4.818769436 = $938,555.49
