EBITDA Calculator: Measuring Core Business Profitability
EBITDA has become one of the most widely used financial metrics in business valuation, credit analysis, and performance benchmarking. By stripping away interest, taxes, depreciation, and amortization, EBITDA provides a standardized view of operating profitability that makes it possible to compare companies across different capital structures, tax jurisdictions, and accounting policies. This free EBITDA calculator computes EBITDA from your income statement inputs, calculates EBITDA margin when you provide revenue, and shows the EV/EBITDA valuation multiple when you enter an enterprise value.
The EBITDA Formula Explained
EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization. Each add-back serves a specific analytical purpose. Adding back interest removes the effect of financing decisions — two identical businesses, one debt-financed and one equity-financed, will have different net incomes solely because of interest expense. Adding back taxes removes geographic and structural tax differences. Adding back depreciation and amortization removes non-cash accounting charges that reduce reported income without affecting cash flow. The result is a proxy for cash operating profit, though it is not the same as free cash flow.
EBITDA Margin and Business Efficiency
EBITDA margin = EBITDA / Revenue. This percentage tells you how much of each revenue dollar the business retains as operating earnings before non-cash charges and financing costs. Improving EBITDA margin over time signals operational leverage — the business is growing revenues faster than costs. Declining EBITDA margins often signal pricing pressure, rising costs, or deteriorating unit economics. Most lenders and private equity buyers focus intently on EBITDA margin trends when evaluating a business.
EV/EBITDA in Business Valuation
Enterprise value divided by EBITDA is the most common valuation multiple in M&A transactions and leveraged buyouts. A business with $500,000 EBITDA being acquired at a 6x multiple has an enterprise value of $3 million. The multiple varies by industry, growth rate, and market conditions. Stable, cash-generative businesses with predictable revenue (such as service businesses with contracts) command higher multiples than cyclical or capital-intensive businesses. High-growth SaaS businesses frequently trade at 10–20x EBITDA or higher.
Adjusted EBITDA in Practice
When preparing for a business sale or raising debt, companies frequently present "Adjusted EBITDA" which adds back one-time expenses, owner compensation above market rate, and non-recurring costs. While legitimate in appropriate contexts, over-adjustment of EBITDA is one of the most scrutinized areas in due diligence. Buyers and lenders will challenge every add-back with documentation, so maintain clear records supporting any adjustments. The goal is to show normalized, sustainable earnings power rather than inflated figures.
