Cost of Equity vs Cost of Capital
Cost of equity refers to the cost of attracting and retaining equity investors and is often calculated using the capital asset pricing model (CAPM). It considers the risk associated with an investment and the return an equity investor expects to receive. The cost of capital represents the minimum return a company must earn on its investments to satisfy its shareholders and lenders. The cost of capital combines debt and equity and is a crucial component in financial decision-making.

Cost of Equity is the returns the company needs to ensure that the investments made meet the capital returns requirements.
It is like a barter system between the company and the market. The company compensates for its asset ownership with its Cost of Equity.
The Cost of Capital is a mixed weighted average of the Cost of debt and the Cost of Equity expected by a company. A company uses the Cost of capital to decide whether a project is worth the expenditure on its resources.
