What Is the Connection between Return on Equity and Cost of Equity?

Return on equity (ROE) and cost of equity (COE) are used to calculate the efficiency of a company’s management. The ROE and COE are also used as inputs for financial ratios such as return on investment (ROI) and economic profit margin.

In this post, I explain why return on equity (ROE) is an important metric for investors. The connection between return on equity and cost of equity.

Understanding Cost of Equity

What is Cost of Equity?

The company’s cost of equity is the amount paid out to equity investors. The cost of equity of a corporation is used to rate the profitability of various investment options, both internally and externally.

Because equity capital is more expensive for enterprises, it is frequently used to complement borrowed funds. ​

What the Cost of Equity Can Tell You

Depending on who you ask, the term “cost of equity” might signify two distinct things. The cost of equity for an investor is the expected rate of return on equity investments. If you are the firm, the cost of equity determines the required rate of return on a project or investment.

What Is the Connection between Return on Equity and Cost of Equity?

Financial resources may be obtained in two ways: by loan or through equity. Debt is less expensive, but it must be repaid by the firm.

Although equity does not demand repayment, it is usually more expensive than debt capital due to the tax advantages of interest payments. Because the cost of equity is higher, the return on equity is frequently higher than the return on debt.

Special Considerations

However, the firm must issue dividends in order to use the dividend capitalization model to calculate the cost of equity. The computation includes future payouts.

According to the rationale behind the calculation, the dividend obligation is the cost of paying shareholders and, by extension, the cost of equity. This strategy has significant drawbacks due to its basic pricing methodology.

The capital asset pricing model may be used to evaluate any stock, regardless of whether or not the company pays dividends. Nonetheless, CAPM theory is more complex. Stocks having higher degrees of volatility and risk, according to this theory, are more costly than the market as a whole.

The CAPM Formula is

Cost of Equity = Risk-Free Rate of Return + Beta × (Market Rate of Return – Risk-Free Rate of Return)

In this calculation, the risk-free rate indicates the return on entirely risk-free investments such as Treasuries. Beta, which is computed by a regression study of the stock price, quantifies risk. When volatility grows, so do the beta and relative risk to the market.

The market rate of return is the average market rate. Higher beta companies often have a higher cost of equity.

Depending on who is speaking, equity cost might have two separate meanings. It serves as a benchmark against which equity investments may be evaluated, and it is also used by businesses to assess the feasibility of initiatives and investments.

How Do You Calculate the Cost of Equity?

The cost of equity can be calculated in two ways. The dividend capitalization model employs the following formula to calculate the cost of equity:

What Is the Connection between Return on Equity and Cost of Equity?

Cost of Equity = DPS CMV + GRD, where DPS is the projected dividend per share for the future year and CMV is the company’s current market value.

The capital asset pricing model (CAPM), on the other hand, analyzes whether or not an investment is appropriately valued in light of its risk, time value of money, and predicted return.

Under this concept, the cost of equity equals the risk-free rate of return plus the beta (Market Rate of Return – Risk-Free Rate of Return).

What Is an Example of Cost of Equity?

Consider the Corporation A invests in the S&P 500, which yields 10% each year. With a beta of 1.1, it is just slightly more volatile than the market as a whole. The current risk-free rate is 1%, as measured by the T-bill.

According to the capital asset pricing model, our cost of equity financing is 1 + 1.1 (10-1) = 10.9 percent when we use the formula Cost of Equity = Risk-Free Rate of Return + Beta (Market Rate of Return – Risk-Free Rate of Return) (CAPM).

Cost of Equity in Financial Modeling

The WACC is commonly used to discount unlevered free cash flow (FCFF). When discounting the FCFF, which is the entire free cash flow available to the firm, the WACC may be used because it considers both stock and debt costs. Discount it at the rate required to fund it (WACC).

To arrive at a discount rate, leveraged free cash flow can be combined with the cost of equity (FCFE). Because FCFE represents the cash available to equity investors, it is permissible to discount it by the cost of equity, which is the cost of obtaining money from equity investors.

Understanding Return on Equity

What is Return on Equity (ROE)?

ROE may be computed by dividing a company’s yearly return (net income) by the entire amount of its shareholders’ equity and expressing the result as a percentage (e.g., 12 percent ).

ROE may also be determined by dividing the company’s dividend growth rate by the rate at which earnings are retained (1 minus the dividend payout ratio).

Return on equity is the ratio of a company’s earnings to its shareholders’ equity, and it is computed using data from both the income statement and the balance sheet.

What Is the Connection between Return on Equity and Cost of Equity?

Return on equity capital is a metric that measures a company’s profitability in relation to the amount of equity capital invested. Profit margin is the amount of profit generated by a corporation for every dollar invested by shareholders.

Return on Equity Formula

The following is the ROE equation:

ROE = Net Income / Shareholders’ Equity 

Return on equity (ROE) is an important metric of an investment’s profitability. By comparing a company’s return on equity (ROE) to the industry average, you might learn something about its competitive advantage.

The return on equity (ROE) may also give information about how the company’s management distributes equity capital for development.

A increasing and constant return on equity (ROE) over time indicates a company that is competent at optimizing returns for its shareholders by reinvesting cash flow in ways that increase output and revenue.

However, if ROE is decreasing, it might be because the company’s management are investing in wasteful ventures.

ROE Formula Drivers

The simplest calculation for return on equity is net income divided by shareholder equity, however this may be broken down further. ROE is determined using a mix of the firm’s ROA and financial leverage, as shown in the image below.

Why is ROE Important?

The Return on Equity (ROE) ratio is a measure of a company’s profitability as evaluated by its owners and investors, with net income serving as the numerator.

The amount of earnings left over after satisfying all tax and regulatory requirements and supporting expansion efforts is reflected in the dividend paid to investors, which is an essential sign of the company’s financial health.

Why Use the Return on Equity Metric?

Return on equity (ROE) is a basic yet useful indicator that both investors and businesses may use to determine whether or not their capital is being properly invested.

Return on equity (ROE) is meaningless in isolation and must be compared to both the company’s historical ROE and the industry ROE average. More financial variables can be reviewed to offer a more sophisticated knowledge of the institution being evaluated.

For a corporation to be appealing to investors, its return on equity (ROE) must be larger than the return on a safer investment.

Effect of Leverage

If a company has a high return on equity, it may imply that it can create profits on its own. However, it understates the risks that must be taken to obtain that return. A firm may employ significant amounts of debt to boost net profit and, by extension, return on equity.

What Is the Connection between Return on Equity and Cost of Equity?

Assume a company has $150,000 in equity and $800,000 in debt; their total capital employed is $1,000,000. The number of assets in use remains constant. The annual interest on such a debt, at 5%, comes to $42,000.

After paying the interest, the business would have a net profit of $78,000, which if reinvested would increase equity by more than 50%. This assumes that the corporation gets a 12 percent return on capital employed (ROCE). Debt, as can be seen, raises the return on equity.

Drawbacks of ROE

Another technique to artificially inflate a company’s ROE is to buy back stock. When management buys back stock on the open market, the number of issued shares is lowered. Return on equity rises as the denominator falls.

Another problem was that intangible assets could not be included in shareholders’ equity under various ROE computations. Intangible assets include things like goodwill, trademarks, copyrights, and patents.

This can lead to incorrect conclusions and make comparisons with organizations that have chosen to account for intangible assets more difficult.

Last but not least, the ratio has a few distinct permutations in terms of its composition, thus there may be some disagreement among specialists.

Similarly, Net Income can stand in for EBITDA and EBIT and be adjusted (or not) for non-recurring variables, whereas Shareholders’ Equity can be computed using either the beginning or ending balances, or as an average of the two.

How to Use Return on Equity

To get the most out of ROE when comparing firms, stick to the same industry, as certain sectors have higher ROEs than others.

Because of intrinsic disparities in industry risk, return on equity (ROE) is frequently higher in cyclical sectors than in conservative ones. A higher cost of capital and cost of equity might be expected from a riskier firm.

It is also important to compare the return on equity against the cost of equity. Companies are creating value by delivering a return on equity that exceeds their cost of equity.

A firm with a 20% ROE would normally attract a share price that is double that of a company with a 10% ROE (all else being equal).

What Is the Connection between Return on Equity and Cost of Equity?

Profitability ratios are used to calculate a company’s ROI, albeit these measurements do not only involve profit margins. Return on equity and cost of equity are two often used profitability indicators.What Is the Connection between Return on Equity and Cost of Equity?

Divide net income by the amount of shareholders’ equity invested in the business to determine return on equity.

The cost of equity of a corporation is the amount of money it needs spend (through dividends and share repurchases) in order to produce money (in the form of external capital from shareholders). The two attributes are inextricably related since a firm cannot exist without the other.

Return on equity is calculated by dividing net income by the average shareholders’ equity on the balance sheet. A company’s average equity is derived by dividing the total of its equity at the start and end of the accounting period by two.

These two figures are often included in a company’s year-end financial reports. Companies can use data to analyze their financial success. A greater rate of return shows that the company is profitable.

The fundamental method for calculating a company’s cost of equity differs somewhat from the one used to value debt. Even if the total cost may reflect the amount of shares required to finance a certain project, the cost of shareholders’ equity is a dividend capitalization model.

The latter formula is used to calculate a company’s profitability; it is composed of dividends per share divided by stock market value plus dividend growth rate.

This model accounts for the reward that investors expect for taking a risk with their money. However, the cost of equity may also be estimated in other ways.

Return on equity and cost of equity are two indicators that firms often assess. This real-time analysis guarantees profitability across any large group of operations or projects.

It is possible for a corporation’s cost of equity to reduce its net income if, for example, the company pays out a lot of dividends or has a high dividend growth rate, both of which increase the amount of money the company has to spend on operations.

What Is the Connection between Return on Equity and Cost of Equity?

These values may also be decided by investors for a certain firm. The information needed for this technique can be found in publicly available financial statements. It assists potential stock purchasers in making educated judgments about where to invest their money.


The higher the return on equity (ROE), the lower the cost of equity. This means that the more profitable a company is, the cheaper it can borrow money for an investment.

The relationship between ROE and cost of equity is like the relationship between a ball and a bat. A baseball bat is stronger than a softball bat, but a softball is easier to hit than a baseball.

There are three main factors that affect a company’s ROE:

1) Profits (profit margin)

2) Taxes (tax rate)

3) Dividends (dividend yield)
