Final answer:
The accounting rate of return (ARR) is a financial ratio used to measure the profitability of an investment. In this case, the ARR for the equipment investment is 10.30%.
Step-by-step explanation:
The accounting rate of return (ARR) is a financial ratio used to measure the profitability of an investment.
To calculate the ARR, you need to divide the average annual net cash inflow by the initial investment cost and express it as a percentage.
In this case, the initial investment cost is $918,000, and the net cash inflows are $146,000 for the first five years and $114,000 for the last five years.
To calculate the ARR, find the average annual net cash inflow by summing the net cash inflows for each period and dividing by the total number of periods. Then divide the average annual net cash inflow by the initial investment cost and multiply by 100 to get the percentage. Finally, round the answer to two decimal places. The calculation would be:
((($146,000 x 5) + ($114,000 x 5)) / 10) / $918,000 x 100 = ARR%
Plugging in the numbers:
((($146,000 x 5) + ($114,000 x 5)) / 10) / $918,000 x 100 = 10.30%
Therefore, the accounting rate of return associated with the equipment investment is 10.30%.
