Cost of capital is the minimum rate of return that a company must earn on its investments. This return helps the company satisfy its investors and maintain its market value. Think of it as the price a company pays for using money from different sources. If a company takes a loan at 10% interest, its cost of capital for that loan is 10%. If the company earns only 8% from its business projects, it will eventually lose money.

WACC is the combined cost of all different sources of capital used by a firm. Each source is given a 'weight' based on its proportion in the total capital. For example, if a firm is 60% debt and 40% equity, WACC will be (0.60 × Cost of Debt) + (0.

For example, if a firm is 60% debt and 40% equity, WACC will be (0.60 × Cost of Debt) + (0.40 × Cost of Equity). It represents the overall risk and cost of the entire business.
