The weighted average cost of capital is calculated on the assumption that the company will maintain the same debt-equity ratio.

Managers should only use WACC as an appropriate discount rate for a project, if the project has a similar level of risk as the company.

The most problematic part of the calculation is making estimations as to the cost of equity.
