Cost of Capital

The cost of capital is the minimum rate of return that a company must earn on its investments and operations to satisfy the expectations of all its capital providers — both equity shareholders and debt holders — and thereby preserve or create economic value. It represents the opportunity cost of investing capital in a particular business, given the returns available on alternative investments of comparable risk. The most widely used measure is the Weighted Average Cost of Capital (WACC), which blends the after-tax cost of debt and the cost of equity — typically estimated using the Capital Asset Pricing Model (CAPM) — weighted by their respective proportions in the company's capital structure. For capital allocation decisions, any investment with an expected return above the cost of capital creates value (positive EVA); investments returning below it destroy value. For equity analysts and investors on Ventura Securities, the cost of capital is a fundamental input in Discounted Cash Flow (DCF) valuation models — small changes in WACC assumptions can produce large swings in intrinsic value estimates, making the cost of capital one of the most consequential and most debated variables in equity valuation.
