About WACC Calculator

WACC (Weighted Average Cost of Capital) represents a company's blended cost of capital across all sources, including equity and debt. It is used as the discount rate in DCF valuation and as a hurdle rate for investment decisions. A lower WACC means the company can raise capital more cheaply, making projects easier to approve. WACC is calculated as (E/V × Re) + (D/V × Rd × (1 - T)).

Frequently Asked Questions

What is WACC?

WACC (Weighted Average Cost of Capital) is the average rate a company expects to pay to finance its assets, weighted by the proportion of equity and debt in its capital structure. It combines the cost of equity and the after-tax cost of debt into a single percentage that represents the minimum return required to satisfy all investors.

How is WACC used in investment decisions?

WACC serves as the hurdle rate or discount rate for evaluating investment projects. If a project's expected return (IRR) exceeds the WACC, it creates value for shareholders and should be accepted. If the IRR is below WACC, the project would destroy value and should be rejected.

What is a good WACC?

A "good" WACC depends on the industry. Technology companies typically have WACC of 8-10%, manufacturing 10-12%, utilities 5-7%, retail 9-11%, and finance 6-8%. Lower WACC means cheaper capital, but extremely low WACC may indicate low risk or high leverage.

What is the difference between WACC and IRR?

WACC is the cost of capital — what the company pays to finance itself. IRR is the return rate of a specific project. The investment rule is simple: accept projects where IRR > WACC. Together, IRR and WACC form the core of capital budgeting decisions.
