EBITA is an acronym for earnings before interest, taxes and amortization. To calculate a company's EBITA, start with its earnings before tax (EBT) , which can be found on the income statement, and add interest and amortization expenses back in.EBITA is a variation of the more commonly used EBITDA, which deducts depreciation expenses.oth measures are sometimes considered indications of cash flow.
