Calculate the NPV of a machine that is bought for $5,000, sold at the end of year 5 for $2,500, and produces the following cash flows: year 1) +$700; year 2) +$600; year 3) +$500; year 4) +$400; year 5) +300, assuming the cost of capital is 6%.

I am using excel to solve the problem, I have the cash flows set up as follows

year	$
0	5000
1	700
2	600
3	500
4	400
5	300

I calculated the NPV using the excel formula (2,155.20) but where do I go from here and how does the 5000 factor in? Do I subtract it from the NPV total?
