Calculating Net Present Value (NPV) and Weighted Average Cost of Capital (WACC) is an important part of any financial analysis project. Both of these financial metrics are used by businesses and investors to assess the value of investments, and to compare the profitability of different proposals. In this blog post, we’ll explore how to calculate NPV with WACC, and why this is a valuable tool for any analyst. We’ll outline the steps necessary to calculate NPV with WACC, and discuss the importance of understanding this metric and its application in the investment process. Additionally, we’ll review the advantages of using this approach to financial analysis, and discuss the importance of understanding the risks associated with any investment. By the end of this post, you’ll have a better understanding of how to calculate NPV with WACC and why it’s an important tool for making informed decisions in the investment process.
What is WACC?
The blended cost of capital from all sources is represented by the weighted average cost of capital (WACC). WACC, on the other hand, considers the cost of each type of capital in accordance with its overall percentage of total capital, then adds the sums. It may include types of debt and equity, such as:
WACC is useful for estimating the cost of each component of a company’s capital structure based on the ratio of its debt to equity and preferred stock. When calculating NPV in financial modeling, it is frequently used as a discount rate. Heres the formula to use to calculate WACC:
(Percentage of capital that is equity x cost of equity) [(Percentage of capital that is debt x cost of debt) x (1 – tax rate)] = Weighted Average Cost of Capital
What is NPV?
The difference between an organization’s cash inflows and outflows over a given period of time is known as net present value (NPV). Inflation and returns are taken into account by NPV, which is frequently advantageous for capital budgeting and investment planning. It enables you to assess the advantages, expenses, and profitability of a potential investment.
Heres the formula to use for calculating NPV:
Net present value is equal to the initial investment’s cost less the first year’s cash flow (1 discount rate), the second year’s cash flow (1 discount rate), and the third year’s cash flow (1 discount rate).
How to calculate NPV with WACC
The procedures to be used for calculating NPV with WACC are as follows:
1. Gather the information
Gather the data required to calculate the NPV and WACC before starting your calculations. This may include information about cash flows, debts and equity. All information should be available in your organizations financial information.
2. Determine the WACC
To calculate the NPV, determine the WACC and use that as the discount rate. Start by dividing the cost of equity by the proportion of capital that is equity. For example, if 40% of the capital is equity and the cost of equity is 11%, you can multiply 40 by 0 11.
Similarly, multiply the cost of debt by the proportion of capital that is debt. If the cost of borrowing is before taxes, divide the result by one less the applicable tax rate. On the other hand, you can omit this additional calculation if the cost of debt is after taxes. Add the outcomes of the two calculation sets together to get the WACC.
3. Calculate the individual present values
It’s crucial to determine the individual present values for each period, such as each month, quarter, or year, before beginning to calculate NPV. WACC should be multiplied by one and converted from a percentage to a decimal. Next, divide the period’s cash flow by the outcome.
Continue this for each period of time until complete. For each additional time period, you can multiply the WACC plus one calculation by itself. For instance, to determine the value for the second month, multiply the value by one plus the WACC, square the result, and then divide the cash flow for the second month by the result.
4. Complete the NPV calculation
Once you calculate all individual present values, add them together. Add the initial investment as a negative amount, or deduct the initial investment from this sum. The final result is your NPV. A positive result means a successful financial outcome and a wise investment, while a negative result means a loss and probably a bad choice.
Example of calculating NPV with WACC
To better understand how to calculate NPV with WACC, use the following example:
Before pursuing another expansion, the owner of OCallaghan Automotive wants to calculate the NPV of their garage expansion to see if it was beneficial. Five years ago, they finished the expansion, and the initial outlay was $500,000 Here’s how they determined the NPV, calculated the WACC, and assessed the outcomes:
WACC calculation
OCallaghan Automotives finances comprise 50% equity and 50% debt. However, the cost of its equity is 13%, and the cost of the debt after tax is 16% Heres the calculation the owner completes to determine the WACC:
(50 x 0. 13) + (50 x . 16) = 6. 5 + 8 = 14. 5% WACC.
NPV calculation
To illustrate the NPV of the garage expansion, the owner makes the following table:
*WACC = 14.5**Year*
*PV formula****Present value**2016**

$159,493.24### Results
According to the calculations, the NPV of the garage investment is $159,493. 24. Although the outcome is favorable and the initial investment has been repaid, the owner is aware that paying off a subsequent expansion may take some time. They consequently opt to postpone finishing a further garage expansion.

FAQ
Is WACC used to calculate NPV?
What is the purpose of WACC? The Weighted Average Cost of Capital (WACC) is the discount rate used to determine a business’s Net Present Value (NPV). As it is thought to represent the company’s opportunity cost, it is also used to assess investment opportunities.
How do you calculate NPV using WACC in Excel?
- NPV is equal to the cash flow / the initial investment, (1 i)t.
- NPV is equal to the difference between the cash invested today and the expected cash flows today.
- ROI = (Total benefits – total costs) / total costs.
How do you calculate NPV and IRR from WACC?
- NPV is equal to the cash flow / the initial investment, (1 i)t.
- NPV is equal to the difference between the cash invested today and the expected cash flows today.
- ROI = (Total benefits – total costs) / total costs.
