Take the first-order derivative of the cost of capital function.
The marginal cost of capital (MCC) is the cost of the last dollar of capital raised, essentially the cost of another unit of capital raised. As more capital is raised, the marginal cost of capital rises.
Marginal revenue/margina utility return from capital represents the benefit of capital. When determining the optimal amount of capital, we must take into account the point when marginal benefit = marginal cost. This optimises profit/utility.
a per unit tax directly affects the marginal cost schedule by increasing the value of each marginal cost at each value by the amount of the tax
Weighted average cost of capital includes cost of debt and cost of equity. Thus irrespective of existing proportion of debt and equity, the marginal cost is always applicable.
Using a hurdle rate can help take the emotion out of defining capital value. This is the advantage of using the marginal cost of capital as the hurdle rate.

The cost to be capital its depend upon the company policy whether they should capitalze the cost or not.
Depending on the capital: i.e. Let's say the capital is a product of your firm such as hammers. To determine the marginal cost, you have to figure out how much it costs to produce 1 unit (or hammer). To determine this, you divide the Total Cost (which is the sum of Total fixed Costs and Total variable costs) by the quantity of units that you are producing. Therefore, if your total cost equals $1000, and you produce 50 hammers, then your marginal cost is $20 because it costed you $20 per hammer.
Marginal cost is
