Definition. EBITDA Margin (TTM) is trailing twelve month earnings before interest, taxes, depreciation and amortization divided by trailing twelve month net sales. EBITDA Margin (Quarterly) is the specified Quarter earnings before interest, taxes, depreciation and amortization divided by Quarter sales.
Proponents of EBITDA argue that it offers a clearer reflection of operations by stripping out non-core. line items that can obscure a companyâs operating performance. In the calculation of EBITDA, interest, which is largely a function of. managementâs choice of financing, is ignored. Taxes are left out because they can vary widely depending on acquisitions and losses in. prior years; this variation can distort net income.
