Cost of Debt
Effective borrowing cost used in WACC, refinancing analysis, leverage decisions, and credit-sensitive valuation.
Cost-of-capital terms for required return, WACC, debt costs, equity costs, capital budgeting, and valuation.
The cost of capital is the return a company must earn on its investments to satisfy the providers of its capital. In practical terms, it is the price of financing.
If a business raises money from shareholders and lenders, those investors expect compensation for time, risk, and opportunity cost. The cost of capital is the rate that captures that expectation.
Cost of capital is one of the most important concepts in corporate finance because it drives:
If a company invests in projects that earn less than its cost of capital, it may be growing in size while destroying value.
Most firms are financed with some combination of:
Each source has its own required return:
When these are combined according to the firm’s capital structure, the result is usually Weighted Average Cost of Capital (WACC).
Providers of capital could always use their money somewhere else. So any company that wants access to funding must offer a return high enough to compete with those alternatives.
That required return depends on:
Safer and more predictable businesses usually face a lower cost of capital than highly uncertain businesses.
When analysts value a company using Discounted Cash Flow (DCF), the cost of capital often becomes the discount rate used to convert future cash flows into present value.
This is why a small change in cost of capital can have a large impact on valuation:
Companies also use cost of capital as a benchmark for investment decisions.
If a project is expected to earn:
This is why cost of capital often serves as a decision threshold alongside metrics such as Net Present Value (NPV) and Internal Rate of Return (IRR).
