EBITDA margin is a measurement of a company's operating profitability as a percentage of its total revenue. It is equal to earnings before interest, tax, depreciation and amortization (EBITDA) divided by total revenue. Because EBITDA excludes interest, depreciation, amortization and taxes, EBITDA margin can provide an investor, business owner or financial professional with a clear view of a company's operating profitability and cash flow.
