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 is "the required rate of return on a portfolio company's existing securities". [1] It is used to evaluate new projects of a company.
An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes. Frequently, economic models posit structural parameters. [1]
The long run total cost for a given output will generally be lower than the short run total cost, because the amount of capital can be chosen to be optimal for the amount of output. Other economic models use the total variable cost curve (and therefore total cost curve) to illustrate the concepts of increasing, and later diminishing, marginal ...
Marginal cost of capital (MCC) schedule or an investment opportunity curve is a graph that relates the firm's weighted cost of each unit of capital to the total amount of new capital raised. The first step in preparing the MCC schedule is to rank the projects using internal rate of return (IRR).
The capital charge is the cash flow required to compensate investors for the riskiness of the business given the amount of economic capital invested. The cost of capital is the minimum rate of return on capital required to compensate investors (debt and equity) for bearing risk, their opportunity cost.
Most models can be written using either churn rate or retention rate. If the model uses only one churn rate, the assumption is that the churn rate is constant across the life of the customer relationship. Discount rate, the cost of capital used to discount future revenue from a customer. Discounting is an advanced topic that is frequently ...
Such costs are separated into a firm's cost of debt and cost of equity and attributed to these two kinds of capital sources. A firm's overall cost of capital, which consists of the two types of capital costs, is then determined as the weighted average cost of capital. Knowing a firm's cost of capital is needed in order to make better decisions ...
Discount rate estimation: Traditionally, DCF models assume that the capital asset pricing model can be used to assess the riskiness of an investment and set an appropriate discount rate. Some economists, however, suggest that the capital asset pricing model has been empirically invalidated.
