The cost of equity capital is the rate a firm pays its shareholders as compensation for investment. It is the desired return investors expect when assuming the investment risk in the company’s equity. Companies utilise the cost of equity capital to ascertain the amount they need to earn to appease their investors. An accurate grasp of this term enables companies to make informed financial decisions and entice investors.
What is Cost of Equity Capital?
The cost of equity capital is the lowest rate of return that a company has to offer to the shareholders to repay them for bearing the risk of investment in the company. Because equity investors do not have an inevitable return, they demand higher returns than debt holders. This cost is significant for firms because it influences their fund-raising capability and financial decision-making.
Cost of Equity Capital Formula
The cost of equity capital is the return shareholders demand to invest in a company. It is estimated through various models, but the most frequently used formula is:
Factors Affecting Cost of Equity Capital
Various determinants affect the cost of equity capital, impacting the return investors require. Company performance, market, business risk, and dividend policy are essential in setting equity financing costs. Knowledge of these determinants allows companies to operate their financial strategy efficiently.
- Business Risk: More risk means more expected returns. Firms operating in volatile industries have a higher cost of equity. Firms with stable earnings and reasonable financial control have less risk, lowering their equity cost.
- Market Conditions: Economic conditions and interest rates affect investor expectations. When interest rates increase, the equity cost increases since investors prefer safer assets. Economic instability also causes investors to want higher returns, increasing the financing costs for the company.
- Company Performance: Profitable firms tend to have lower equity costs. Consistent profits and sound financial health minimise investor risk, making equity financing more affordable. High-debt, loss-making companies tend to be plagued by high equity costs.
- Dividend Policy: Firms offering constant dividends will likely experience lower equity costs. Investors also desire stable incomes, which reduces risk and asked-for returns. Firms providing uneven or zero dividends can suffer higher equity costs because investors want higher payments for uncertainty.
Components of Cost of Equity Capital
Equity capital cost comprises various elements influencing how investors view risk and return. The knowledge of these factors enables better decision-making.
- Risk-Free Rate: The risk-free rate is the rate of return for risk-free securities like government securities. It forms a benchmark against which equity cost is calculated. An increase in the risk-free rate raises the cost of equity.
- Market Risk Premium: This refers to the extra return investors anticipate above the risk-free rate for investing in the stock market. The higher the market risk premium, the more investors demand returns for bearing risk. It is computed as:
Market Risk Premium = Expected Market Return − Risk-Free Rate - Beta (Systematic Risk): Beta quantifies a stock’s risk relative to the market. A beta of 1 indicates that the stock moves with the market, and a beta greater than 1 signifies greater volatility. The higher the beta, the higher the required return. High-beta stocks are more risky but have the potential to deliver higher returns.
- Company-Specific Risk: Besides market risk, company-specific characteristics like management action, capital structure, and competitive standing also affect equity cost. Good financial stability and effective management can reduce company-specific risks.
How to Calculate Cost of Equity Capital?
There are various methods of calculating the cost of equity capital based on the financial approach. Some of them are listed below.
Capital Asset Pricing Model (CAPM) Method
CAPM (Capital Asset Pricing Model) is one of the companies’ most widely used models to determine the cost of equity. The Cost of Equity Capital formula in CAPM is:
Cost of Equity Capital=Risk-Free Rate+(Beta×Market Risk Premium)
Example: Risk-Free Rate = 4%, Market Risk Premium = 6%, Beta = 1.2
Cost of Equity Capital=4%+(1.2×6%)=11.2%
Dividend Discount Model (DDM) Method
For companies that pay dividends, the Cost of Equity Capital can be calculated using:
Example: D1 = ₹2 per share, P0 = ₹40 per share and g = 5%
Cost of Equity Capital=(2/40)+5%=10%
Cost of Equity Capital vs Cost of Debt
Firms fund their operations by utilising debt and equity. The cost of equity capital and debt are different in numerous ways.
The cost of equity capital is the return shareholders demand when they invest in a company. It tends to be greater than the cost of debt since shareholders bear more significant risk. Debt holders, on the other hand, get fixed interest payments, so debt is less risky. However, the interest on debt is tax-deductible, so the company’s overall cost is lower.
Assuming additional debt does not impact ownership, issuing additional equity dilutes the current shareholder’s interest. As equity investors take on greater risk, they require higher returns. Debt financing, however, is less expensive but has to be repaid with interest. Companies have to strike a balance between both to minimise costs and risks effectively.
| Aspect | Cost of Equity Capital | Cost of Debt |
| Definition | The return required by shareholders | Interest rate on the company’s debt |
| Risk | High, as shareholders bear the risk | Low, as debt holders have fixed returns |
| Tax Impact | Not tax-deductible | Tax-deductible |
| Expected Return | Generally higher than debt | Lower compared to equity |
Methods of Calculating Cost of Equity Capital
There are several methods to calculate the cost of equity capital. Each has its advantages and disadvantages. This approach suits stable firms but might not be appropriate for companies with volatile earnings.
CAPM Method
The capital asset pricing model (CAPM) is a widely used method for estimating the cost of equity capital. It considers market risk by incorporating the risk-free rate, beta, and market risk premium. It relies on historical data, though, and future risks might not be predicted accurately. Businesses utilise this method when they can rely on reliable market data. CAPM remains ineffective for companies with unique risk factors as it doesn’t account for company-specific risks.
Dividend Discount Model (DDM)
The dividend discount model (DDM) can be applied to firms that pay consistent dividends. It is based on the premise that the stock’s current price is the present value of all future dividends. The model needs the company’s dividend per share, growth rate, and stock price. This approach cannot be applied to companies that do not pay dividends. It also assumes that dividend growth is constant, which is not always true. Firms with non-regular dividend payments are not able to utilise this method.
Bond Yield Plus Risk Premium (BYPRP) Approach
This technique determines the cost of equity capital by applying a risk premium to the yield of the firm’s bond. This technique is appropriate for firms that have issued bonds and enjoy a consistent credit standing. Because yields on bonds mirror the firm’s riskiness, placing a risk premium there provides an estimate of the anticipated return for shareholders. It is challenging to quantify the risk premium due to its fluctuation depending on market conditions and investor sentiments. The formula is:
Earnings Capitalization Method
This approach estimates the cost of equity capital based on earnings per share and market price per share. It is easy and best suited for firms with consistent earnings. Investors use this approach to compare various stocks based on profitability. It does not take into account market volatility or growth in future earnings. This approach will not give correct results if a company has an extremely volatile stock price. The formula is:
