Your question is WACC Calculation & Rates. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you calculate the WACC, and what are the implications of a change in the risk-free rate?
Explain the WACC components, including cost of equity, after-tax cost of debt, and capital structure weights. Then describe how a change in the risk-free rate affects the discount rate, valuation, and potentially equity risk premiums and borrowing costs. No company-specific financial data are provided, so focus on the framework and directional implications.
