Understanding EV/EBITDA

Enterprise Value (EV) = Market Cap + Total Debt - Cash

EBITDA = Earnings Before Interest, Taxes, Depreciation & Amortization

EV/EBITDA is commonly used for comparing companies because:

  • It accounts for debt levels (capital structure neutral)
  • It removes effects of different depreciation policies
  • It can be compared across countries with different tax rates
  • It can remain available when net income is negative, if EBITDA is positive

Aon plc EV/EBITDA Ratio Formula & Definition

EV/EBITDA = Enterprise Value / EBITDA (TTM)

Enterprise value to EBITDA is a capital-structure-neutral valuation multiple, useful for comparing companies with different debt levels and tax rates.
