1. What is Net Present Value (NPV)?

Net Present Value (NPV) is a financial metric used to evaluate the profitability of an investment or project. It represents the difference between the present value of cash inflows and the present value of cash outflows over a period of time.

2. How Does the Calculator Work?

The calculator uses the NPV formula:

\[ NPV = \sum_{t=1}^{n} \left[ \frac{Cash\ Flow_t}{(1 + r)^t} \right] - Initial\ Investment \]

Where:

\( Cash\ Flow_t \) — Cash flow at time period t (USD)
\( r \) — Discount rate (decimal)
\( t \) — Time period (years)
\( n \) — Total number of periods
\( Initial\ Investment \) — Initial cash outflow (USD)

Explanation: The formula discounts future cash flows to their present value using the discount rate, then subtracts the initial investment to determine the net value.

3. Importance of NPV Calculation

Details: NPV is crucial for capital budgeting decisions. A positive NPV indicates that the projected earnings exceed the anticipated costs, making it a profitable investment. NPV accounts for the time value of money, making it superior to simple payback period calculations.

4. Using the Calculator

Tips: Enter initial investment as a positive number, discount rate as a decimal (e.g., 0.10 for 10%), number of periods, and cash flows for each period. Negative cash flows represent costs, positive cash flows represent revenues.

5. Frequently Asked Questions (FAQ)

Q1: What does a positive NPV mean?
A: A positive NPV indicates that the investment is expected to generate more value than it costs, making it a financially viable project.

Q2: How do I choose the discount rate?
A: The discount rate should reflect the risk of the investment. Common choices include the company's cost of capital, weighted average cost of capital (WACC), or a risk-adjusted rate.

Q3: What is the difference between NPV and IRR?
A: NPV calculates the absolute dollar value of an investment, while IRR (Internal Rate of Return) calculates the percentage return that makes NPV equal to zero.

Q4: Can NPV be negative?
A: Yes, a negative NPV means the investment is expected to lose money and should typically be rejected.

Q5: What are the limitations of NPV?
A: NPV relies on accurate cash flow projections and appropriate discount rate selection. It doesn't account for non-financial factors and may be less useful for comparing projects of different sizes.
