What is the Net Present Value Rule?
Let me tell you directly: the net present value rule means that as a company manager or investor, you should only put money into projects or deals that show a positive net present value (NPV). You need to steer clear of anything with a negative NPV. This rule comes straight from net present value theory, and it's a straightforward way to make smart investment choices.
Understanding the Net Present Value Rule
Based on net present value theory, if you invest in something with an NPV above zero, it should logically boost your company's earnings. For investors, this means growing shareholder wealth. Sometimes companies go for projects with neutral NPV if they promise future benefits that are hard to measure right now, or if they open doors to more investments down the line.
That said, not every company sticks to this rule perfectly. If a company is buried in debt, it might skip or delay a project with positive NPV to handle the immediate financial pressure. Poor governance can also lead to ignoring or messing up NPV calculations.
How the Net Present Value Rule is Used
You see net present value often in capital budgeting, where it factors in the time value of money (TVM). This concept holds that money you have now is worth more than the same amount in the future because of what you can earn with it today. To apply this, a business runs a discounted cash flow (DCF) calculation to gauge how a project might change its wealth.
The calculation discounts projected cash flows back to their present value using the company's weighted average cost of capital (WACC). Essentially, a project's NPV is the present value of the net cash inflows it should generate minus the upfront capital needed.
In decision-making, like whether to acquire something, you use the net present value rule to evaluate. If the NPV comes out negative (less than zero), expect a net loss, so according to the rule, don't pursue it. A positive NPV (greater than zero) signals profit, so consider moving forward. For neutral NPV (equal to zero), there's no big gain or loss expected, and you weigh in non-monetary factors, like intangible benefits, to decide.
