Unlevered Beta Calculator
Unlevered beta, also known as asset beta, is a financial metric that measures the systematic risk of a company’s assets, excluding any financial leverage (debt). It shows how volatile a company is compared to the market, based solely on its core business operations—not its capital structure.
This metric is crucial for comparing companies with different debt levels, and it’s widely used in valuation models like the Capital Asset Pricing Model (CAPM).
Unlevered Beta Formula
To calculate unlevered beta, we use the following formula:
Unlevered Beta = Levered Beta / [1 + (1 – Tax Rate) × (Debt / Equity)]
Where:
- Levered Beta reflects both business and financial risk.
- Tax Rate is the corporate tax rate (as a decimal).
- Debt/Equity Ratio shows how much debt a company uses relative to equity.
This formula helps remove the effects of leverage, isolating the inherent business risk.
How to Use the Unlevered Beta Calculator
- Input Levered Beta – Get this from financial platforms or public stock data.
- Enter the Tax Rate – Typically, use the company’s effective tax rate or your country’s corporate tax rate.
- Provide the Debt/Equity Ratio – Found on a company’s balance sheet.
- Click “Calculate” – The tool will compute unlevered beta instantly.
Example Calculation
Let’s say:
- Levered Beta = 1.5
- Tax Rate = 30%
- Debt/Equity Ratio = 0.6
Plug into the formula:
Unlevered Beta = 1.5 / [1 + (1 – 0.3) × 0.6]
= 1.5 / [1 + 0.7 × 0.6]
= 1.5 / [1 + 0.42]
= 1.5 / 1.42
= 1.056
So, the business risk of the company (without debt) is approximately 1.06.
Why Is Unlevered Beta Important?
- ✅ Pure Business Risk: Reflects the true operational risk of a company.
- ✅ Valuation Accuracy: Used in CAPM to estimate the cost of equity without the distortion of leverage.
- ✅ Comparable Analysis: Allows fair comparison between companies with different capital structures.
- ✅ M&A and LBO Modeling: Critical in transactions where financial structure changes significantly.
Unlevered Beta vs Levered Beta
| Feature | Unlevered Beta | Levered Beta |
|---|---|---|
| Includes Debt Risk? | ❌ No | ✅ Yes |
| Used For | Comparables, asset risk | Stock risk, equity volatility |
| Volatility Level | Lower | Higher |
| Stability | More stable | Changes with leverage |
When to Use Unlevered Beta
- During Discounted Cash Flow (DCF) valuation
- When comparing companies in different industries
- When analyzing private firms or startups with no market beta
- In mergers and acquisitions, where financial structure will change
Relevering Beta
Once you have the unlevered beta, you can re-lever it using your own capital structure to estimate equity risk in a new scenario:
Relevered Beta = Unlevered Beta × [1 + (1 – Tax Rate) × (Debt / Equity)]
This helps investors model the potential risk profile if a company adjusts its financing strategy.

FAQs – Unlevered Beta Calculator
1. Can unlevered beta be negative?
Yes, but it’s rare. A negative beta means the asset moves inversely to the market.
2. Why remove debt from beta?
To isolate business risk and allow comparisons regardless of financial structure.
3. What’s a typical unlevered beta?
Ranges from 0.5 to 1.5, depending on the industry. For example, utilities tend to have low unlevered betas.
4. How is it used in CAPM?
It helps compute the expected return on equity before adjusting for financial leverage.
5. Is unlevered beta always lower than levered beta?
Yes—because levered beta includes financial risk, it will be equal to or greater than unlevered beta.
6. Can I use this for private companies?
Yes—estimate the levered beta from public comps, then use this calculator to find unlevered beta.
7. Is the tax rate important?
Yes—taxes reduce the cost of debt, which affects the financial risk calculation.
8. Where do I find the Debt/Equity ratio?
From the company’s balance sheet or financial data providers.
9. What if a company has no debt?
The unlevered and levered beta will be the same.
10. Does industry affect unlevered beta?
Absolutely. Tech companies may have high unlevered betas; utilities tend to be low.
Conclusion
Unlevered beta is an essential metric for financial professionals who want to understand a company’s true operational risk. By removing the effects of debt, it provides a cleaner, more comparable measure of volatility across firms.
