interest rate and risk are the only two factors involved in your question. if money is tight, then people are gonna charge you more to use it-hence increase in interest. also if the economy is red-hot the federal reserve steps in and says, "lets raise interest rates and everyone will stop doing so much business because interest is higher". if your business venture or loan is "risky" then a company is going to charge you a higer rate of return on their money- hence you pay more for the money.
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.

A procedure through which it is considered by keeping in view economics approach that the cost of labor does not increase its marginal product cost i.e. labor cost less than marginal cost.
element of risk is the factor which causes the cost of capital to increase as much the risk as much the cost of capital.
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 or incremental cost of capital is cost of the additional capital raised in a given period
Marginal cost is
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.
Disadvantage of share capital is that it increases the risk of default which causes the increase in cost of capital.
increase output
Take the first-order derivative of the cost of capital function.
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.
