1. What is NPV Using WACC?

Net Present Value (NPV) using Weighted Average Cost of Capital (WACC) is a financial metric that calculates the present value of future cash flows discounted at the company's WACC, minus the initial investment. It helps in evaluating the profitability of an investment or project.

2. How Does the Calculator Work?

The calculator uses the NPV formula:

\[ NPV = \sum_{t=1}^{n} \frac{CF_t}{(1 + WACC)^t} - \text{Initial Investment} \]

Where:

\( CF_t \) — Cash flow at time period t (currency)
\( WACC \) — Weighted Average Cost of Capital (decimal)
\( t \) — Time period
\( n \) — Total number of periods
Initial Investment — Initial cash outflow (currency)

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

3. Importance of NPV Calculation

Details: NPV is a crucial capital budgeting tool that helps businesses determine whether an investment will generate positive returns. A positive NPV indicates a profitable investment, while a negative NPV suggests the investment may not be worthwhile.

4. Using the Calculator

Tips: Enter the initial investment amount, WACC as a decimal (e.g., 0.08 for 8%), number of periods, and the expected cash flows for each period. All values must be valid (non-negative numbers).

5. Frequently Asked Questions (FAQ)

Q1: What is a good NPV value?
A: A positive NPV indicates that the investment is expected to generate value above the cost of capital. The higher the positive NPV, the better the investment.

Q2: How does WACC affect NPV?
A: Higher WACC decreases the present value of future cash flows, resulting in a lower NPV. Lower WACC increases NPV.

Q3: Can NPV be negative?
A: Yes, a negative NPV indicates that the investment is expected to destroy value and not meet the required rate of return.

Q4: What are the limitations of NPV?
A: NPV relies on accurate cash flow projections and appropriate WACC estimation. It doesn't account for intangible benefits or strategic value.

Q5: How is WACC calculated?
A: WACC = (E/V × Re) + (D/V × Rd × (1 - Tc)), where E is equity, D is debt, V is total capital, Re is cost of equity, Rd is cost of debt, and Tc is corporate tax rate.
