Understanding Cost of Capital and Prime Interest Rate in Business Financing
What is Cost of Capital?
- Cost of Debt: The effective interest rate a company pays on its borrowed funds. This includes loans, bonds, and other forms of debt.
- Cost of Equity: The return required by equity investors, considering the risk of their investment. This includes common and preferred stock.
Where:
- ( E ) = Market value of equity
- ( D ) = Market value of debt
- ( V ) = Total market value of the company’s financing (equity + debt)
- ( Re ) = Cost of equity
- ( Rd ) = Cost of debt
- ( Tc ) = Corporate tax rate
- Benchmark Rate: The prime rate is used as a starting point for determining the interest rates on loans.
- Economic Indicator: Changes in the prime rate reflect broader economic policies and conditions.
- Impact on Borrowing Costs: A higher prime rate increases borrowing costs, while a lower prime rate reduces them.
Relationship Between Cost of Capital and Prime Interest Rate
- Rising Prime Rate: Increases the cost of debt, leading to higher interest expenses for businesses. This can raise the WACC, making capital projects more expensive.
- Falling Prime Rate: Lowers the cost of debt, reducing interest expenses. This can lower the WACC, making capital projects more attractive.
Example:
- Interest Rate: 6%
- Tax Rate: 30%
- Cost of Debt = 6% × (1−0.30) = 4.2%
Where:
- ( Rf ) = Risk-free rate
- ( \beta ) = Beta (measure of stock volatility relative to the market)
- ( Rm ) = Expected market return
- Risk-free Rate: 2%
- Beta:1.2
- Expected Market Return: 8%
Cost of Equity = 2% + 1.2 × (8%−2%) = 9.2%
