About this tool
EBITDA & Margin Calculator is a free, in-browser tool that computes EBITDA — earnings before interest, taxes, depreciation and amortization — a common proxy for operating cash profitability used in valuation and lending. Enter the five line items from your income statement and the result updates instantly, calculated locally with nothing uploaded.
EBITDA = net income + interest + taxes + depreciation + amortization. Starting from net income, you add back financing costs (interest), taxes, and the two non-cash charges (depreciation and amortization) to isolate core operating performance. The tool also shows EBIT = net income + interest + taxes (before the non-cash add-backs), and, if you enter revenue, the EBITDA margin = EBITDA ÷ revenue × 100.
Use it to compare companies with different tax positions, debt loads or asset bases, or to compute the metric an acquirer or bank will multiply. Net income can be negative for a loss-making period; the add-backs still apply.
