Real-World Example
A small business owner is considering purchasing a new piece of equipment that will increase production efficiency. First, they calculate the NPV of the investment by estimating the future cash flows generated by the increased efficiency, discounting them at an appropriate rate, and comparing the result to the initial cost of the equipment. If the NPV is positive, the investment is profitable, and the business owner may purchase the equipment.
Formula Examples
Suppose an investor is considering an investment with the following cash flows and a required rate of return of 10%:
Year 1: $5,000
Year 2: $6,000
Year 3: $7,000
Initial Investment: $15,000
Step 1: Calculate the present value of each cash flow:
PV Year 0 = -$15,000 / (1 + 0.10)^0 = -$15,000
PV Year 1 = $5,000 / (1 + 0.10)^1 = $4,545.45
PV Year 2 = $6,000 / (1 + 0.10)^2 = $4,958.68
PV Year 3 = $7,000 / (1 + 0.10)^3 = $5,259.20
Step 2: Sum the present values of cash flows:
NPV = -$15,000 + $4,545.45 + $4,958.68 + $5,259.20 = -$236.67 US dollars
