Calculate weighted average cost of capital using CAPM or manual assumptions, then turn the result into a cleaner DCF narrative, investment committee memo, or board-ready valuation slide.
Use market values and a defendable equity assumption set.
This screens below the usual software / technology range. Pressure-test beta, equity risk premium, and debt assumptions before using it in a board or investment memo.
Use a 8.21% WACC as the base discount rate. Capital structure is 71.43% equity and 28.57% debt, with cost of equity at 10.00% and after-tax debt at 3.75%.
Keep the formula explicit so finance reviewers can trace the logic quickly.
Equity = $500m
Debt = $200m
Total capital = $700m
Equity weight = 71.43%
Debt weight = 28.57%
Benchmark midpoint = 10.50%
Cost of equity = 10.00%
Contribution = 7.14%
CAPM = 4.50% + 1.10 x 5.00%
Pre-tax debt = 5.00%
After-tax debt = 3.75%
Contribution = 1.07%
Use ranges as sanity checks, not substitutes for company-specific judgment.
| Industry | Typical WACC | Notes |
|---|---|---|
| Software / Technology | 9% to 12% | Higher growth and beta usually push cost of equity up. |
| Healthcare | 7% to 9% | Mix of resilient cash flows and growth-oriented segments. |
| Industrials | 8% to 10% | Cyclicality and capex intensity often keep WACC mid-range. |
| Consumer Staples | 6% to 8% | Defensive sectors often benefit from lower perceived risk. |
| PE / Leveraged Buyout | 10% to 14% | Leverage and execution risk usually require a stronger hurdle rate. |
| Utilities | 5% to 7% | Regulated and stable cash flows can support lower discount rates. |
Lead with the discount rate and explain whether it reflects normal trading risk, leverage, or a more conservative board view.
Waterfall or bridge showing equity and debt contributions
Show how much of the blended rate comes from equity versus debt and whether the current structure is intentional or temporary.
Donut chart or capital-structure split tile
Flag beta, risk-free rate, and market premium as the assumptions most likely to trigger diligence or IC questions.
Sensitivity table or assumption callout panel
This example uses the same assumptions loaded into the calculator by default.
Equity value = $500m and debt value = $200m, so total capital is $700m.
CAPM cost of equity = 4.50% + 1.10 x 5.00% = 10.00%.
After-tax cost of debt = 5.00% x (1 - 25%) = 3.75%.
Final WACC = 71.43% x 10.00% + 28.57% x 3.75% = 8.21%.
Use WACC as the base discount rate, then run a sensitivity table with terminal growth and WACC ranges before socializing the valuation.
Compare project ROI, IRR, or synergy cases against WACC to show whether management is creating or destroying value.
Explain the rate, defend the beta and premium assumptions, and isolate what would move the valuation most in downside cases.
Use the calculation to frame whether a target or project deserves a company WACC, a project premium, or a more conservative acquisition hurdle.

Using book debt and stale equity values instead of market values.

Forgetting to tax-adjust debt and overstating the debt contribution.
Treating WACC as a precision number instead of a range worth sensitizing.
WACC is the standard discount rate for DCF valuation, capital budgeting, valuation review, and board-level capital allocation decisions.
Use market values whenever possible. WACC is meant to reflect the return demanded by current capital providers, so market capitalization and current debt value are usually more defensible than book values.
Yes. You can derive cost of equity from risk-free rate, beta, and equity risk premium, or switch to manual mode if your valuation model already uses a fixed cost of equity assumption.
Interest expense is tax-deductible in many jurisdictions, so the effective cost of debt is reduced by the tax shield: cost of debt × (1 - tax rate).
No. WACC is a base discount rate. Analysts often adjust it for country risk, project risk, integration risk, or division-specific economics when the asset risk differs from the company average.
Use the calculator first, then generate a valuation or board slide that explains the rate, the capital mix, and the assumptions a CFO, IC lead, or board member will challenge first.
