What is Cost of Capital?

The Cost of Capital is the required rate of return a company must earn on an investment or project to justify the risk. It is a weighted average of the company's cost of debt and cost of equity, known as the Weighted Average Cost of Capital (WACC).

For Startups: Startups typically have a high cost of capital due to their high-risk nature. This means they need to pursue projects and strategies that offer very high potential returns to be attractive to investors.

For SaaS: For a SaaS company, the cost of capital is a key input in valuation models like the Discounted Cash Flow (DCF) analysis. A lower cost of capital, often achieved as the company matures and becomes less risky, leads to a higher valuation.

Calculation: WACC = (E/V * Re) + (D/V * Rd * (1-Tc)), where E is market value of equity, D is market value of debt, V is total value (E+D), Re is cost of equity, Rd is cost of debt, and Tc is the corporate tax rate.
