Unlevered Beta — Smart Financial Analysis
Calculate unlevered beta (asset beta) from levered beta using the Hamada equation. Strips financial risk for pure business risk comparison.
Did our AI summary help? Let us know.
Unlevered beta (asset beta) measures a company's pure business risk without the effect of financial leverage. Unlevering beta lets you compare companies with different capital structures on equal footing. The Hamada equation (1972) adjusts levered beta for the tax shield of debt: βu = βl / [1 + (1-t)(D/E)]. Levered beta (equity beta) includes both business and financial risk.

Unlevered beta (asset beta) measures pure business risk by stripping out the effect of financial leverage. The Hamada equation: βu = βl / (1 + (1-t)D/E). It removes debt-related risk so you can compare companies with different capital structures. Essential for M&A valuation, peer analysis, and WACC. CFA Institute and Damodaran recommend unlevering before comparing betas across firms.

Key Takeaways
- • Unlevered beta = pure business risk; levered beta = business + financial risk
- • Hamada: βu = βl / [1 + (1-t)(D/E)] — accounts for tax shield of debt
- • Re-lever: βl = βu × [1 + (1-t)(D/E)] for target capital structure
- • Use unlevered beta when comparing firms with different D/E ratios
Did You Know?
How Does Unlevered Beta Work?
The Hamada Formula
βu = βl / [1 + (1-t)(D/E)]. Divides levered beta by a factor that captures the tax-adjusted leverage effect. Higher D/E and lower tax rate increase the denominator, reducing unlevered beta.
Why Tax Matters
Interest is tax-deductible, so debt creates a tax shield. (1-t) adjusts for this. At t=21%, each dollar of debt adds 0.79×D/E to the leverage factor.
Re-levering for Valuation
After unlevering comparables, re-lever with the target firm's D/E and tax rate to get equity beta for CAPM. Essential when valuing an acquisition with a different capital structure.

Frequently Asked Questions
What is unlevered beta?
Unlevered beta (asset beta) measures a company's pure business risk without the effect of financial leverage. It strips out debt-related risk to show how the underlying assets would move relative to the market if financed entirely with equity. Formula: βu = βl / (1 + (1-t) × D/E).
Why unlever beta?
Unlevering beta lets you compare companies with different capital structures on equal footing. A highly leveraged firm may have a high levered beta due to debt, not business risk. Unlevered beta isolates operational risk for M&A valuation, peer comparison, and WACC calculation.
Hamada equation?
The Hamada equation (1972) adjusts levered beta for the tax shield of debt: βu = βl / [1 + (1-t)(D/E)]. It assumes perpetual debt and constant tax rate. Named after Robert Hamada, it extends Modigliani-Miller theory to systematic risk.
Unlevered vs levered beta?
Levered beta (equity beta) includes both business and financial risk. Unlevered beta removes financial risk. For a firm with debt, levered beta > unlevered beta. At D/E=0, they are equal. The gap reflects the risk premium from leverage.
How to re-lever beta?
Re-lever: βl = βu × [1 + (1-t)(D/E)]. Use the target company's D/E and tax rate. Essential when valuing an acquisition or projecting cost of equity under a different capital structure than comparables.
Where to find levered beta?
Levered beta is published by Bloomberg, Yahoo Finance, and financial databases. Or estimate via regression: regress stock returns on market returns; the slope is beta. Use 2–5 years of monthly data for reliability.
