What is the WACC Calculator (Weighted Average Cost of Capital)?
Weighted average cost of capital from equity, debt and preferred stock.

Valuing a stock step by step
Begin with the P/E ratio and PEG ratio to see what the market pays for earnings and growth. Then check quality with ROE and ROIC, and compare ROIC with the WACC.
For a second opinion, estimate intrinsic value with the Dividend Discount Model Calculator or the Graham Number Calculator, then compute the margin of safety against today’s price.
- Returns. EPS, EPS growth, dividend yield and payout ratio measure what shareholders earn.
- Risk. Beta, unlevered beta and portfolio beta measure sensitivity to the market.
- Position tools. Stock average, stock split and market cap calculators keep your records straight.

Formula and how it works
Example with real numbers
Here is the WACC Calculator (Weighted Average Cost of Capital) using the default values shown in the calculator above:
Inputs
| Market value of equity ($) | 8,000,000 |
|---|---|
| Market value of debt ($) | 3,000,000 |
| Preferred stock ($) | 500,000 |
| Cost of equity (%) | 11 |
| Cost of debt (%) | 6.5 |
| Cost of preferred (%) | 7 |
| Tax rate (%) | 23 |
Results
| WACC | 9.26% |
|---|---|
| Total capital | $11,500,000.00 |
| Debt weight | 26.09% |
With these inputs the calculator returns WACC: 9.26%. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Market value of equity ($) from 8,000,000 to 9,600,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| WACC | 9.26% | 9.47% | +2.3% |
| Total capital | $11,500,000.00 | $13,100,000.00 | +13.9% |
| Debt weight | 26.09% | 22.9% | -12.2% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
