Using the Cost of Capital Calculator

WACC (Cost of Capital) Calculator computes:

  • Cost of Equity

  • After-tax Cost of Debt

  • Weighted average Cost of Capital

The cost of capital represents an investor's required rate of return on an investment and should be a company's minimum acceptable rate of return for anticipated investments. It should be a company's objective to earn rates of return above its cost of capital to maximize its shareholder's investment.

Note:

For all numeric values, use integers with decimal places. For example, enter 5.57% as 5.57, not .0557.
