The weighted average cost of capital for Synopsys, Inc. at 2026-06-30, calculated using the Baratelli Institute methodology and sourced to the most recent public filings. The number below is a practitioner reference — free to use, free to cite, refreshed quarterly.
| Component | Value | Source / Assumption |
|---|---|---|
| Risk-free rate (Rf) | 4.25% | 10-year US Treasury yield at snapshot date |
| Equity risk premium (ERP) | 5.55% | Damodaran implied ERP, June 2026 update |
| Beta (β) | 1.10 | 5-year weekly regression vs S&P 500, Blume-adjusted |
| Cost of equity (Ke) | 10.4% | CAPM: Rf + β × ERP = 4.25% + 1.10 × 5.55% |
| Pre-tax cost of debt (Kd) | 4.70% | Current-yield estimate on senior unsecured debt at issuer's rating |
| Marginal tax rate (t) | 13.0% | Blended federal + state; company-specific effective rate |
| After-tax cost of debt | 4.1% | Kd × (1 − t) = 4.70% × 87.0% |
| Equity weight (E/V) | 98.0% | Market value of equity ÷ total capitalization |
| Debt weight (D/V) | 2.0% | Market value of debt ÷ total capitalization |
| WACC | 10.2% | (E/V × Ke) + (D/V × Kd after-tax) |

Use this WACC as the discount rate in an enterprise-value DCF, the hurdle rate for value-based management analysis of SNPS, or the cost-of-capital anchor when comparing SNPS to peers in the Application Software industry. For equity-only valuation frameworks (dividend discount models, residual income), use the cost of equity Ke of 10.4% instead of the blended WACC.
The methodology page walks each input in more depth and explains where reasonable practitioners disagree. If your own model uses different inputs, the companion Excel workbook exposes every formula so you can substitute directly.
