The cost created for the rest of the firm as a consequence of undertaking a project is determined by considering various factors. One important factor to consider is the opportunity cost. This refers to the potential benefits or profits that could have been gained by choosing an alternative project or investment instead of the current one.

Another factor to consider is the marginal cost of capital. This represents the additional cost incurred by the firm to raise additional funds for the project. It takes into account the cost of borrowing or issuing new equity, and reflects the cost of financing the project.

The company's weighted average cost of capital (WACC) is also relevant in determining the cost created for the rest of the firm. WACC is the average rate of return required by the firm's investors, taking into account the cost of both debt and equity financing. It represents the minimum return that the firm needs to generate in order to satisfy its investors.

Lastly, the project's weighted average cost of capital (PWACC) is another consideration. This is the specific WACC calculated for the project, taking into account the project's risk and the specific financing structure used for the project.

In summary, the cost created for the rest of the firm as a consequence of undertaking a project is influenced by the opportunity cost, the marginal cost of capital, the company's WACC, and the project's PWACC.
