What is Incremental Cost of Capital?
Let me explain incremental cost of capital directly: it's a key term in capital budgeting that describes the average cost a company pays to issue one additional unit of debt or equity. This cost changes based on how much more debt or equity you're planning to issue. If you can calculate it accurately, along with the effects of adding more equity or debt, you'll help your business cut down on overall financing expenses.
Understanding Incremental Cost of Capital
The cost of capital is essentially what it costs a company to get the funds needed for its operations. It depends on the financing method—it's the cost of equity if you're using equity, or the cost of debt if you're issuing debt. Most companies mix both, so the overall cost comes from a weighted average of all sources, which we call the weighted average cost of capital (WACC).
This cost acts as a hurdle rate that your company must clear to create value, and it's central to capital budgeting decisions on whether to fund projects with debt or equity. The 'incremental' part focuses on how issuing more equity or debt impacts your balance sheet. Each new debt issuance might raise your borrowing costs, reflected in the coupon rate you pay investors, which ties to your creditworthiness and market conditions. In short, incremental cost of capital is the weighted-average cost of new debt and equity issued in a reporting period.
Key Takeaways
- The incremental cost of capital estimates how adding more debt or equity will affect a company's balance sheet.
- Knowing the incremental costs of capital allows a company to assess whether a project is a good idea given the effect it will have on overall borrowing costs.
- Investors watch for changes in the incremental cost of capital, as a rise can be a sign that a company is leveraging itself too much.
How the Incremental Cost of Capital Affects a Stock
When a company's incremental cost of capital starts to climb, investors see it as a red flag for a riskier capital structure. You might start questioning if the company has taken on too much debt relative to its cash flow and balance sheet. The critical shift happens when investors steer clear of the company's debt due to risk concerns, prompting the company to seek equity funding instead. This can lead to investors backing away from the shares, worried about debt levels or dilution based on how the new capital is raised.
Incremental Cost of Capital and Composite Cost of Capital
Incremental cost of capital connects to composite cost of capital, which is the cost for a company to borrow based on the proportions of debt and equity it holds. You might also hear composite cost of capital called weighted average cost of capital. The WACC formula weights the costs of debt and equity by the company's capital structure to find the overall cost. A high composite cost means high borrowing expenses, while a low one indicates lower costs.
