Why It's Important to Unlever the Beta When Making WACC Calculations (2024)

Companies and investors review the weighted average cost of capital (WACC) to evaluate the returns that a firm needs to realize to meet all of its capital obligations, including those of creditors and stockholders. Beta is critical to WACC calculations, where it helps 'weight' the cost of equity by accounting for risk. WACC is calculated as:

WACC = (weight of equity) x (cost of equity) + (weight of debt) x (cost of debt).

However, since not all capital obligations involve debt (and therefore default or bankruptcy risk), comparisons between different obligations require a beta calculation that is stripped of the impact of debt. This process is called "unlevering the beta."

What Is Levered Beta?

The equity beta is the volatility of a company’s stock compared to the broader market. A beta of 2 theoretically means a company’s stock is twice as volatile as the broader market. The number that shows up on most financial sites, such as Yahoo! or Google Finance, is the levered beta.

Levered beta is characterized by two components of risk: business and financial. Business risk includes company-specific issues, while the financial risk is debt or leverage related. If the company has zero debt, then unlevered and levered beta are the same.

Unlevering the Beta

WACC calculations incorporate levered and unlevered beta, but it does so at different stages when being calculated. Unlevered beta shows the volatility of returns without financial leverage. Unlevered beta is known as asset beta, while the levered beta is known as equity beta. Unlevered beta is calculated as:

Unlevered beta = Levered beta / [1 + (1 - Tax rate) * (Debt / Equity)]

Unlevered beta is essentially the unlevered weighted average cost. This is what the average cost would be without using debt or leverage. To account for companies with different debts and capital structure, it’s necessary to unlever the beta. That number is then used to find the cost of equity.

To calculate the unlevered beta, an investor must gather a list of comparable company betas, take the average and re-lever it based on the company’s capital structure that they’re analyzing.

Re-Levering the Beta

After finding an unlevered beta, WACC then re-levers beta to the real or ideal capital structure. The ideal capital structure comes into play when looking to purchase the company, meaning the capital structure will change. Re-levering the beta is done as follows:

Levered beta = Unlevered beta * [1 + (1 - Tax rate) * (Debt / Equity)]

In a sense, the calculations have taken apart all of the capital obligations for a firm and then reassembled them to understand each part's relative impact. This allows the company to understand the cost of equity, showing how much interest the company is required to pay per dollar of finance. WACC is very useful in determining the feasibility of future capital expansion.

Unlevered Beta Example

Company ABC is looking to figure out its cost of equity. The company operates in the construction business where, based on a list of comparable firms, the average beta is 0.9. The comparable firms have an average debt-to-equity ratio of 0.5. Company ABC has a debt-to-equity ratio of 0.25 and a 30% tax rate.

The unlevered beta is calculated as follows:

0.67 = 0.9 / [1 + (1 - 0.3) * (0.5)]

Then to re-lever the beta we calculate the levered beta using the unlevered beta above and the company’s debt-to-equity ratio:

0.79 = 0.67 *[1 + (1 - 0.3) * (0.25)]

Now, the company would use the levered beta figure above, along with the risk-free rate and the market risk premium, to calculate its cost of equity.

Unlevered beta

Unlevered beta
Unlevered beta (or asset beta) measures the market risk of the company without the impact of debt. 'Unlevering' a beta removes the financial effects of leverage thus isolating the risk due solely to company assets. In other words, how much did the company's equity contribute to its risk profile.

Why is it important to unlever beta? ›

Unlevered beta removes any beneficial or detrimental effects gained by adding debt to the firm's capital structure. Comparing companies' unlevered betas give an investor clarity on the composition of risk being assumed when purchasing the stock.

What is the impact of beta in WACC? ›

The higher the beta, the higher the the required return on capital, according to the capital asset pricing model. In other words, the opportunity cost of capital is higher. Since WACC measures the opportunity cost of capital for a firm, it follows that the higher the beta, the higher the WACC.

Should I use levered or unlevered beta? ›

Unlevered beta is used when an investor wants to measure the performance of a stock, which is publicly traded, concerning market movements without the positive effect of debt taken up by the company. A levered beta indicates a company's stock price sensitivity to overall market movements.

What is unlevered or levered beta in WACC? ›

Levered beta includes both business risk and the risk that comes from taking on debt. However, since different firms have different capital structures, unlevered beta (asset beta) is calculated to remove additional risk from debt in order to view pure business risk.

How do you unlever a company's beta? ›

To calculate unlevered beta, you need to remove the effect of debt from levered beta. The effect of debt is calculated by multiplying the debt-equity ratio (DE ratio) with (1 - tax rate) and then adding 1 to this value. You can then calculate the unlevered beta by dividing the levered beta by the effect.

How does beta affect valuation? ›

Beta is a concept that measures the expected move in a stock relative to movements in the overall market. A beta greater than 1.0 suggests that the stock is more volatile than the broader market, and a beta less than 1.0 indicates a stock with lower volatility.

How does beta affect cost of capital? ›

In contrast, the unlevered cost implies the firm is 100% equity funded.

Why is beta important in CAPM? ›

Beta is useful in determining a security's short-term risk, and for analyzing volatility to arrive at equity costs when using the CAPM. However, since beta is calculated using historical data points, it becomes less meaningful for investors looking to predict a stock's future movements.

What affects levered beta? ›

Debt affects a company's levered beta in that increasing the total amount of a company's debt will increase the value of its levered beta. Debt does not affect a company's unlevered beta, which by its nature does not take debt or its effects into account.

What is the difference between levered IRR and WACC? ›

The primary difference between WACC and IRR is that where WACC is the expected average future costs of funds (from both debt and equity sources), IRR is an investment analysis technique used by companies to decide if a project should be undertaken.
