Unlevered Beta Calculator

Remove the effect of debt from beta to estimate the asset beta. This page also keeps the formula, examples, FAQs, and references close by so you can check the result with confidence.

What This Unlevered Beta Calculator Helps You Do

Unlevered beta scales the levered beta down by the leverage and tax effect. Review the formula and examples below if you want to see how the result is derived.

This page is meant to give you a fast answer, but it also helps you double-check the math before you make a decision. Start with the inputs that you already know, run the calculation, and then compare the output with the formula, examples, and FAQs below so you can see whether the answer fits the situation you are modeling.

If the result looks off, the usual causes are a unit mismatch, a missing decimal, the wrong scenario, or a value that needs to be entered as a rate instead of a total. The notes on this page are designed to make those checks easy without forcing you to leave the calculator and search for context elsewhere.

  • Use the calculator first for a quick estimate.
  • Use the formula to understand how the result is built.
  • Use the examples to compare common use cases.
  • Use the references when the answer depends on a standard or assumption.

Common Checks

A quick result is useful, but the best result is one that still makes sense when you look at it a second time. If you are comparing scenarios, try changing one input at a time so you can see which variable has the biggest impact on the final answer. That makes it much easier to spot whether the calculation matches your expectations.

It also helps to keep the context of the problem in mind. A calculator can tell you the math, but you still need to decide whether the input represents a total, a rate, an average, or a category-specific assumption. When in doubt, start with a simple example from the page and scale up from there.

  • Check that every unit matches the rest of the problem.
  • Keep rates, totals, and averages separate.
  • Adjust one variable at a time when testing scenarios.
  • Use the smallest realistic input first, then scale upward.

Scenario Planning

This calculator is especially useful when you want a quick answer before you commit time, money, or effort. Try one baseline input set, then change a single number and compare the result so you can see how sensitive the answer is to that variable.

That makes the page useful for more than just arithmetic. It becomes a small decision aid that helps you compare options, test assumptions, and explain the final number with confidence when you need to share it with someone else.

Quick Answer: Unlevered beta scales the levered beta down by the leverage and tax effect. Review the formula and examples below if you want to see how the result is derived.

How to Calculate Unlevered Beta Calculator

  1. Enter the levered beta: Use the beta for the equity or project.
  2. Enter tax rate and leverage: These are needed to strip out the debt effect.
  3. Read the unlevered beta: This gives the asset beta before financing effects.

Unlevered Beta Calculator Formula

Unlevered beta = Levered beta / (1 + (1 - Tax rate) × Debt-to-equity).
Variable Meaning Unit
Levered beta Observed equity beta x
Tax rate Corporate tax rate %
Debt-to-equity Leverage ratio x

Worked Examples

USA - Moderately leveraged company
  • Levered beta: 1.5
  • Tax rate: 21%
  • Debt-to-equity ratio: 0.8

Result: 1.13

Leverage increases beta, so the asset beta is lower than the equity beta.

USA - Solve for levered beta
  • Unlevered beta: 1.0
  • Tax rate: 21%
  • Debt-to-equity ratio: 0.8

Result: 1.63

This is the levered beta after adding the capital structure effect.

USA - Solve for debt-to-equity
  • Levered beta: 1.5
  • Tax rate: 21%
  • Unlevered beta: 1.0

Result: 0.63

This is the leverage needed to move from asset beta to levered beta.

How to Interpret Your Results

Range Meaning Action
Low beta Less sensitive to market swings Compare with peers and capital structure.
Moderate beta Average market sensitivity Use it in WACC or valuation models.
High beta More volatile than the market Check whether leverage is inflating the figure.
