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.

When analyzing a business project or investment:
- NPV (Net Present Value): Gives you a concrete dollar figure of expected profit (or loss) in today's money. An NPV > 0 implies a profitable investment.
- IRR (Internal Rate of Return): The exact discount rate that makes the NPV equal to zero. If the IRR exceeds your required rate of return (hurdle rate), the project is generally acceptable.
- Profitability Index (PI): Shows the ratio of value created to the initial investment (PV of future cash flows / Initial Cost). A PI > 1.0 means the project destroys value.
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.
