What It Measures
EBITDA is a metric that shows the cash-based earning power generated by a company's core business activities, with the effects of interest, taxes, and depreciation/amortization removed. Because it allows comparison without the effects of differences in the scale of capital investment, debt levels, and depreciation methods (straight-line, declining-balance, etc.), it is sometimes used to compare the earning power of companies across industries and countries.
Relationship with the EV/EBITDA Multiple
EBITDA is also used as the denominator of the EV/EBITDA multiple, which shows how many times a company's EBITDA its enterprise value (EV) represents. This multiple is sometimes referenced as a rough guide to how many years' worth of EBITDA would be needed to cover the cost of an acquisition, but it is only one reference metric and does not guarantee any investment outcome.
