(Answer #1). Economic cost is a more comprehensive idea that accounting costs. Accounting costs only include what economists call explicit costs.. These are the amounts that a firm actually pays out to other people in the process of producing their product.ence, the difference between the economic cost and accounting cost is that the economic cost comprises the opportunity cost, while the accounting cost does not. Although the accounting costs are very important to company owners, the economists are mainly focused on economic costs rather than accounting costs.
In economics and accounting, the cost of capital is the cost of a company's funds (both debt and equity), or, from an investor's point of view the required rate of return on a portfolio company's existing securities.It is used to evaluate new projects of a company.his means, for instance, that the past cost of debt is not a good indicator of the actual forward looking cost of debt. Once cost of debt and cost of equity have been determined, their blend, the weighted average cost of capital (WACC), can be calculated.
