💡

Expert Tip

Cost of equity represents the return required by investors to compensate them for stock-specific market risks.

How this Calculator Works

This calculator determines the required return rate on common stock using the Capital Asset Pricing Model (CAPM) approach. It establishes the minimum return rate required by equity investors to compensate them for holding the asset. Corporate planners use it to evaluate project feasibility.

Formula & Methodology

Cost of Equity = Risk-Free Rate + Beta * Market Risk Premium - Risk-Free Rate is the yield of safe assets (e.g. government bills). - Beta is the stock's systemic risk coefficient. - Market Risk Premium is the expected market return minus the risk-free rate.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

A stock has a Beta of 1.15. The risk-free rate is 4%, and the market risk premium is 6%. 1. Multiply Beta by the market risk premium: 1.15 * 6% = 6.9%. 2. Add the risk-free rate: 4% + 6.9% = 10.9%. Result: The cost of equity is 10.9%.

FAQ

What is WACC and why is it crucial for equity valuation?
Weighted Average Cost of Capital (WACC) represents a company's required average return on debt and equity capital. It is used as the hurdle rate to discount future cash flows in DCF valuation models.
How does stock Beta measure systematic risk?
A stock beta of 1.0 means price volatility matches the broader market index. Beta > 1.0 indicates higher volatility, while Beta < 1.0 reflects lower systematic volatility.
Should valuation multiples be evaluated in isolation?
No. Valuation ratios (P/E, EV/EBITDA, P/B) should always be benchmarked against industry peer groups, historical trading averages, and expected earnings growth (PEG ratio).
