WACC Calculator – Easily Calculate Your Weighted Average Cost of Capital

Ever wondered how successful companies assess their cost of capital? Introducing The (Weighted Average Cost of Capital) WACC Calculator, a financial tool used in corporate finance to determine the average rate of return a company is expected to pay to all its security holders.

It plays a pivotal role in assessing investment decisions, evaluating capital projects, and determining a company’s overall cost of capital.

What is WACC (Weighted Average Cost of Capital)?

WACC stands for Weighted Average Cost of Capital. It is a financial metric that represents the average cost a company expects to pay to finance its assets.

WACC takes into account the cost of both debt and equity capital, and it is weighted based on the proportion of each component in the company’s capital structure.

Understanding the WACC Formula is crucial for assessing a company’s financial standing and making strategic investment decisions.

The WACC formula combines the cost of debt and equity to reflect the company’s capital structure.

WACC Formula

WACC = E / (E + D) × Ce + D / (E + D) × Cd × (100% – T)

WACC – Weighted average cost of capital, expressed as a percentage;

E – Equity

D– Debt

Ce – Cost of equity

Cd – Cost of debt and

T – Corporate tax rate.

How to Calculate WACC with our WACC Calculator?

Now you can easily Calculate Your Weighted Average Cost of Capital with the WACC Calculator by following these simple steps.

1. Gather Information

Collect the necessary information.

E (Equity)- The market value of the company’s equity.

D (Debt)- The market value of the company’s debt.

Ce (Cost of Equity)- The cost of raising funds from investors (shareholders).

Cd (Cost of Debt)- The cost of borrowing money.

T (Tax Rate)- The corporate tax rate.

2. Use the formula.

WACC = E / (E + D) × Ce + D / (E + D) × Cd × (100% – T)

Insert the values into the formula.

3. Calculate

Perform the calculations to find the WACC.

WACC Example

Let’s say your company has,

Equity (E) is $1,000,000

Debt (D) is $500,000

Cost of Equity (Ce) is 10%

Cost of Debt (Cd) is 5%

Tax Rate (T) is 30%

Applying WACC Formula =WACC = E / (E + D) × Ce + D / (E + D) × Cd × (100% – T)


Perform the calculations to find the WACC.




Multiply by 100 to express as a percentage.


So, in this example, the Weighted Average Cost of Capital (WACC) is 7.84%.

Importance of WACC in different fields

The Weighted Average Cost of Capital (WACC) is a crucial financial metric with significant importance in various fields. Here are some key areas where WACC plays a vital role.

Investment Decision Making

Corporate Investments

WACC is used to evaluate the attractiveness of potential investments or projects. Companies compare the expected return on investment with the WACC. If the expected return is higher than the WACC, the investment may be considered.


Company Valuation

WACC is used in discounted cash flow (DCF) analysis to determine the present value of a company’s future cash flows. It helps in estimating the intrinsic value of a business and guiding investors in making investment decisions.

Capital Budgeting

Project Evaluation

WACC is applied in capital budgeting to assess the feasibility of capital-intensive projects. It serves as the discount rate to determine the net present value (NPV) of future cash flows associated with a project.

Cost of Capital

Financing Decisions

WACC guides companies in making optimal financing decisions by considering the costs of both debt and equity. It helps in finding the right balance between debt and equity to minimize the overall cost of capital.

Mergers and Acquisitions

Company Valuation

WACC is a critical factor in assessing the value of a target company during mergers and acquisitions. It influences negotiations and helps in determining a fair purchase price.

Performance Measurement

Shareholder Value

WACC is used to evaluate a company’s ability to create value for shareholders. If a company generates returns higher than its WACC, it is considered to be creating value.

Risk Assessment

Financial Risk

WACC reflects the risk associated with a company’s capital structure. A higher WACC may indicate higher financial risk, influencing strategic decisions and risk management.

Credit Rating

Borrowing Costs

Credit rating agencies often consider a company’s WACC when assigning credit ratings. A lower WACC may lead to better credit terms and lower borrowing costs.

Regulatory Compliance

Regulatory Reporting

WACC is sometimes used in regulatory reporting and compliance, especially in industries where regulators set pricing based on a company’s cost of capital.

In brief, WACC is a versatile tool that helps decision-making from investment and finance to strategic planning and risk management.

In addition to assessing traditional return on investment (ROI), businesses can leverage the WACC Calculator to optimize their capital structure, ultimately influencing metrics like Gross Margin Return on Investment (GMROI) for a comprehensive financial analysis.

Factors Affecting WACC Calculation

Cost of Equity (Ce)Market conditions: Impact of interest rates and investor sentiment. Higher market volatility may result in a higher cost of equity.
Cost of Debt (Cd)Creditworthiness: Credit ratings affect borrowing costs.
Higher credit ratings may lead to lower cost of deb
Corporate Tax Rate (T)Tax environment: Changes in tax laws or rates affect WACC.
Lower tax rates reduce the tax shield on interest payments.
Capital StructureDebt-Equity mix: Proportion of debt and equity in the structure.
Higher debt proportion often leads to a lower WACC.
Market vs. Book ValuesAsset valuation: Market values provide a more accurate reflection.
Reflects current market perceptions of the company’s worth
Risk-Free RateGovernment bond yields Benchmark for the cost of equity.
Changes in rates influence the cost of equity and WACC.
Beta (β)Systematic risk: A measure of a stock’s sensitivity to the market.
Higher beta implies higher systematic risk and cost of equity.
Dividend PolicyDividend payments: Impact on the cost of equity.
Higher dividends may result in a higher cost of equity.
Industry/Economic ConditionsEconomic environment and industry trends affect risk perception.
Industries facing challenges may have a higher WACC
Market ConditionsExchange rate fluctuations: Relevant for companies in multiple currencies.
Currency risk can influence WACC calculation.
Interest Rate EnvironmentChanges in interest rates impact both cost of debt and equity.
Rising rates generally lead to higher costs of capital.
