How do organizations calculate various costs, and what do these calculations mean to business?
QveST [7]

Answer:

See the explanation section

Explanation:

Organizations calculate various costs with the help of the weighted average cost of capital. It is a significant cost measurement system through which organizations can calculate the cost of debt after tax, cost of new equities, cost of existing equities, and cost of preferred shares. WACC can be a benchmark for the organization. A firm needs to know those costs because it can make sure that whether those projects are running smoothly to continue or running worse to reject.

Another significant cost measurement method is the net present value. With the help of NPV, a business can make sure about a project to accept it or reject it.
