1. What is Net Present Value (NPV)?

Net Present Value (NPV) is a core financial metric used in capital budgeting and investment planning to analyze the profitability of a projected investment. It calculates the difference between the present value of cash inflows and the present value of cash outflows over a period of time. Because of the "time value of money", a dollar earned in the future is worth less than a dollar today.

3. Incorporating Taxes & Terminal Value

Real-world projects don't exist in a vacuum. Most business cash flows are subject to corporate tax rates, reducing the net inflow. Additionally, at the end of a project's life, equipment may be sold or an asset liquidated, providing a final lump sum known as the Salvage or Terminal Value. Our calculator lets you seamlessly overlay these advanced variables onto your uniform or variable cash flows.

Frequently Asked Questions

What does a Negative NPV indicate?

A negative NPV means that the discounted present value of all future cash inflows is less than your initial investment. Financially, undertaking the project will result in a net loss in value based on your specified discount rate.

How do I choose a Discount Rate?

The discount rate (often called the hurdle rate or cost of capital) usually represents the rate of return you could earn on an alternative investment of similar risk. For corporations, it is typically their Weighted Average Cost of Capital (WACC).

What is the Payback Period?

The payback period tells you exactly how many years it will take for your accumulated net cash inflows to equal your initial investment cost, essentially telling you when you "break even". (Note: standard payback period does not discount the cash flows).
