Weighted Average Cost of Capital

The Weighted Average Cost of Capital (WACC), which is a measure of how much it costs a business to raise money from various sources like debt and equity, shows how much it does. It is derived by averaging the costs of each capital source according to their share in the overall capital structure.

Consider a corporation that has $100 million in debt with a 5% interest rate and $200 million in equity with a projected return of 10%. The WACC of this company would be:

WACC = (5% x $100 million / $300 million) + (10% x $200 million / $300 million)

WACC = 1.67% + 6.67%

WACC = 8.33%

Why is WACC crucial? because it indicates the bare minimum return on investment that a business must achieve in order to pay off its debts and satisfy its shareholders. A corporation will lose value for its owners if it invests in a project with a return that is less than its WACC. On the other hand, a business will benefit its owners if it invests in a project with a return that exceeds its WACC.

The profitability and viability of various initiatives and investments can therefore be assessed using WACC as a standard. By selecting the debt-to-equity ratio that reduces WACC and increases value, it can also assist a company in optimizing its capital structure.

WACC does not have a set value, though. According to a number of variables, including market conditions, interest rates, risk tolerance, tax rates, and growth prospects, it may alter over time. As a result, it's critical to regularly update and track WACC in order to reflect a company's and its environment's current state.
