EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is one of the most widely used metrics in business valuation and performance analysis. It strips out the effects of financing decisions (interest), accounting conventions (depreciation and amortization), and tax environments to give a cleaner view of operational profitability. Investment bankers, private equity firms, and analysts use EBITDA multiples to value and compare businesses across industries.
