The weighted average cost of capital (WACC) is a calculation of a business cost of a capital in which each
category of capital is proportionately weighted. All sources of capital, including common stock, preferred
stock, bonds, and any other long-term debt, are included in a WACC Calculation. If unsure, use 8.25% as a
starting point.
A business's WACC increases as the rate of return on equity increases, as an increase in WACC denotes a decrease
in valuation and an increase of risk.
