Based on the fundamentals, the investor will project the future cash flows and discount them using the WAC; with that, the value of the firm can be calculated. From the Value of Firm, value of debt will be deducted to find the value of equity. Value of equity will be divided by the number of equity shares , leading to the per-share value of the company.

One can simply compare this value and the current market price CMP of the company to decide whether it is worth the investment or not. Some important inferences from WACC can be drawn to understand various important issues that the management of the company should address. Thus, the WACC can be optimized by adjusting the debt component of the capital structure.

The lower the WACC, the higher the valuations of the company. A lower WACC also widens the scope of the company by allowing it to accept low return projects and still create value. The increase in the magnitude of capital also tends to increase the WACC. With the help of a WACC schedule and project schedule, an optimal capital budget can be worked out for the company.

## What is the Formula for Weighted Average Cost of Capital (WACC)?

WACC is an important metric used for various purposes, but it must be used very carefully. The market values should be determined carefully and accurately. Faulty calculations of WACC will also result in faulty investment decisions. There are other issues, such as no consideration given to the floatation cost, which should not be ignored.

The complications increase if the capital consists of callable, puttable or convertible instruments, warrants , etc. He is passionate about keeping and making things simple and easy. Running this blog since and trying to explain "Financial Management Concepts in Layman's Terms". We simply use the market interest rate or the actual interest rate that the company is currently paying on its obligations.

Keep in mind, that interest expenses have additional tax implications. Interest is typically deductible, so we also take into account the amount of tax savings the company will be able to take advantage of by making its interest payments, represented in our equation Rd 1 — Tc.

## Importance and Use of Weighted Average Cost of Capital (WACC)

To put it simply, the weighted average cost of capital formula helps management evaluate whether the company should finance the purchase of new assets with debt or equity by comparing the cost of both options. Financing new purchases with debt or equity can make a big impact on the profitability of a company and the overall stock price. Executives and the board of directors use weighted average to judge whether a merger is appropriate or not. Investors and creditors, on the other hand, use WACC to evaluate whether the company is worth investing in or loaning money to. As the weighted average cost of capital increases, the company is less likely to create value and investors and creditors tend to look for other opportunities.

You can think of this as a risk measurement. Investors use a WACC calculator to compute the minimum acceptable rate of return. An investor would view this as the company generating 10 cents of value for every dollar invested. This cent value can be distributed to shareholders or used to pay off debt. This means the company is losing 5 cents on every dollar it invests because its costs are higher than its returns. No investor would be attracted to a company like this. We will now look at some of the practical problems in applying that formula. But where do you get the data? A little work and a dash of judgment are needed to go from one to the other.

Table 4. These bonds have a coupon rate of 8 percent and mature at the end of 12 years. The figures shown in Table 4. Sometimes the differences between book values and market values are negligible. The interest rate on bank loans is usually linked to the general level of interest rates. Most financial managers most of the time are willing to accept the book value of bank debt as a fair approximation of its market value.

## Importance and Use of Weighted Average Cost of Capital (WACC)

Since the bonds were originally issued, long term interest rates have risen to 9 percent. The really big errors are likely to arise if you use the book value of equity rather than its market value. But perhaps Big Oil has been able to find projects that were worth more than they originally cost or perhaps the value of the assets has increased with inflation. Perhaps investors see great future investment opportunities for the company. You can see that debt accounts for These are the proportions to use when calculating the weighted-average cost of capital.

Notice that if you looked only at the book values shown in the company accounts, you would mistakenly conclude that debt and equity each accounted for 50 percent of value. If there is any chance that the firm may be unable to repay the debt, however, the yield to maturity of 9 percent represents the most favorable outcome and the expected return is lower than 9 percent. For most large and healthy firms, the probability of bankruptcy is sufficiently low that financial managers are content to take the promised yield to maturity on the bonds as a measure of the expected return.

But beware of assuming that the yield offered on the bonds of Fly-by-Night Corporation is the return that investors could expect to receive. Earlier we showed you how to use the capital asset pricing model to estimate the expected rate of return on common stock. The capital asset pricing model tells us that investors demand a higher rate of return from stocks with high betas. To measure the expected market risk premium, they usually look back at capital market history, which suggests that investors have received an extra 8 to 9 percent a year from investing in common stocks rather than Treasury bills.

Yet wise financial managers use this evidence with considerable humility, for who is to say whether investors in the past received more or less than they expected, or whether investors today require a higher or lower reward for risk than their parents did? Whenever you are given an estimate of the expected return on a common stock, always look for ways to check whether it is reasonable. This constant-growth dividend discount model is widely used in estimating expected rates of return on common stocks of public utilities.

Utility stocks have a fairly stable growth pattern and are therefore tailor-made for the constant-growth formula. Remember that the constant-growth formula will get you into trouble if you apply it to firms with very high current rates of growth. Such growth cannot be sustained indefinitely. Using the formula in these circumstances will lead to an overestimate of the expected return. Beware of False Precision. Do not expect estimates of the cost of equity to be precise.

Even if your formulas were right, the required inputs would be noisy and subject to error. Thus a financial analyst who can confidently locate the cost of equity in a band of two or three percentage points is doing pretty well. Or suppose that Geothermal is contemplating investment in oil refining. It could therefore try to estimate WACC for a sample of oil refining companies. We report estimates of oil industry WACCs at the end of the next section.

Now all you need to do is plug the data in Table 4. The Figure 4. The latest estimates seem to fall below 10 percent, less than our hypothetical figure for Big Oil. Some of that decline can be attributed to a decline in interest rates over the s and early s. We have included a plot of the risk-free rate rf in Figure 4.

However, the spread between the WACC estimates and these interest rates has also narrowed, suggesting that investors viewed the oil business as less risky in the early s than a decade earlier.

The large oil companies sampled are involved in some risky activities, such as exploration, and some relatively safe activities, such as franchising retail gas stations. The industry average will not be right for everything the industry does. The weighted-average cost of capital formula solves those problems.

The weighted-average cost of capital is the rate of return that the firm must expect to earn on its average-risk investments in order to provide a fair expected return to all its security holders. We use it to value new assets that have the same risk as the old ones and that support the same ratio of debt.

But often it is used as a companywide benchmark discount rate; the benchmark is adjusted upward for unusually risky projects and downward for unusually safe ones.

There is a good musical analogy here. Most of us, lacking perfect pitch, need a welldefined reference point, like middle C, before we can sing on key. But anyone who can carry a tune gets relative pitches right.
