To calculate EBITDA margin, add a company’s net income, interest expense, income taxes, depreciation, and amortization to arrive at EBITDA, then divide that figure by total revenue and multiply by 100. If a business produces $300,000 of EBITDA on $1,200,000 of revenue, its EBITDA margin is 25%. The metric strips out financing choices, tax environments, and non-cash accounting charges so you can compare operational profitability across companies that look very different at the bottom line.
One thing to know before you start: EBITDA is not a standard accounting measure under Generally Accepted Accounting Principles, so companies aren’t required to report it directly on their financial statements. You’ll usually need to build the number yourself from the line items that are reported.
The Formula and What Each Add-Back Does
The calculation has two steps. First, build EBITDA from net income:
- EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization
Then convert the dollar figure into a margin:
- EBITDA Margin = (EBITDA ÷ Total Revenue) × 100
Each add-back has a specific purpose. Adding interest back removes the effect of how the company chose to finance itself, so a business funded entirely by equity and one loaded with debt can be compared on equal footing. Adding taxes back neutralizes differences in tax jurisdictions, credits, and corporate structures. Adding depreciation and amortization back eliminates non-cash charges that reduce reported earnings but don’t actually leave the company’s bank account during the period.
Skip one of the add-backs and you get a different metric. Net income plus interest and taxes alone produces EBIT, or operating income, which still carries the non-cash drag of depreciation. That makes EBIT a tougher standard for capital-heavy businesses. EBITDA is more forgiving, and that forgiveness is both its appeal and its biggest limitation.
Where to Find Each Number
Public companies file annual reports on Form 10-K with the Securities and Exchange Commission, and those filings include audited financial statements with every line item you need.1Cornell Law School Legal Information Institute (LII). Form 10-K For private companies, you’ll work from internally prepared income statements and cash flow statements. Either way, six numbers come out of those documents.
Revenue and Net Income
Revenue sits at the top of the income statement, sometimes labeled “Total Revenue,” “Net Sales,” or “Gross Sales.” If the statement breaks out returns and allowances, use the net revenue figure. Revenue becomes the denominator of your margin, so this is the one number you can’t afford to pull from the wrong line.
Net income sits at the bottom of the same statement, after every expense, interest payment, and tax has been deducted. That’s your starting point for the add-back math.
Interest Expense and Income Taxes
Interest expense is the cost of borrowed money the company paid during the period on loans, bonds, or credit lines. It’s typically its own line item just above pre-tax income. Income tax expense appears right below pre-tax income and reflects what the company owes in federal, state, and local taxes for the period. For corporations, that obligation is reported to the IRS on Form 1120.2Internal Revenue Service. About Form 1120, U.S. Corporation Income Tax Return
Depreciation and Amortization
These two often take more digging because they aren’t always broken out as separate income statement lines. Depreciation reflects the gradual loss of value in physical assets like equipment, buildings, and vehicles over their useful lives. Amortization does the same thing for intangible assets like patents, software licenses, and customer lists. Neither involves an actual cash outflow in the period.
When the income statement buries depreciation and amortization inside broader categories like “operating expenses” or “cost of goods sold,” check the statement of cash flows. Under the indirect method, which most companies use, depreciation and amortization appear near the top of the “Cash Flows from Operating Activities” section as add-backs to net income. The notes to the financial statements are another reliable source, especially when a company breaks out depreciation by asset category.
A Worked Example
With the six numbers collected, the math is straightforward addition. Start with net income and add each item back:
- Net Income: $150,000
- + Interest Expense: $30,000
- + Income Tax Expense: $45,000
- + Depreciation: $60,000
- + Amortization: $15,000
- = EBITDA: $300,000
Now divide by total revenue. If revenue for the same period was $1,200,000:
$300,000 ÷ $1,200,000 = 0.25, and 0.25 × 100 = 25% EBITDA margin.
That 25% means the company keeps 25 cents of every revenue dollar after paying cash operating costs, before accounting for how it’s financed, what it owes in taxes, and how it depreciates its assets.
What a Good EBITDA Margin Looks Like
A margin number means little in isolation. A 25% EBITDA margin is excellent for a grocery retailer and mediocre for a software company, because different industries have fundamentally different cost structures. Software scales without proportional cost increases. Grocery retail runs on volume because cost of goods sold eats most of the revenue. The useful comparison is always within the same industry.
Based on January 2026 data covering U.S. public companies, representative EBITDA margins by sector include:3NYU Stern. Operating and Net Margins by Sector (US)
- Software (System & Application): 35.93%
- Semiconductors: 36.77%
- Pharmaceuticals: 33.59%
- Healthcare Products: 20.34%
- Hospitals and Healthcare Facilities: 15.80%
- Retail (General): 10.11%
- Retail (Grocery and Food): 5.40%
- Retail (Building Supply): 14.21%
- Computer Services: 8.98%
If you’re evaluating a competitor and their margin runs five or more percentage points above yours in the same sector, the gap usually points to differences in pricing power, labor costs, or supply chain efficiency worth investigating.
Adjusted EBITDA Is a Different Number
If you’re calculating EBITDA to evaluate a private company that’s being sold, be aware that buyers and sellers rarely work with the raw figure. They work with “adjusted EBITDA,” which starts with standard EBITDA and then adds back expenses that wouldn’t exist under new ownership or that don’t reflect the true recurring cost of running the business. Common add-backs include above-market owner compensation, personal expenses run through the business, one-time legal or inventory losses, salaries paid to family members above market rate, and owner-only retirement contributions.
The SEC requires that any version of EBITDA with adjustments beyond the standard four add-backs be labeled “Adjusted EBITDA” rather than plain “EBITDA.”4U.S. Securities and Exchange Commission. Non-GAAP Financial Measures Private companies face no such labeling requirement, which means the “EBITDA” figure in a sales memorandum may already include adjustments you haven’t been told about. If the number you’re reviewing came from someone else’s spreadsheet, confirm which add-backs are in it before you treat it as comparable to anything.
What EBITDA Margin Doesn’t Tell You
EBITDA is one of the most widely used profitability metrics and one of the most criticized. The margin you just calculated has three specific blind spots.
It Ignores Capital Expenditures
EBITDA adds back depreciation and amortization without accounting for the capital expenditures needed to replace the assets. A manufacturing company might show a healthy 20% EBITDA margin while spending every dollar of that margin, and then some, on new equipment. Warren Buffett has been vocal about this flaw, arguing that depreciation represents a real economic cost because assets wear out and must eventually be replaced, regardless of whether the accounting entry involves cash this quarter. For capital-intensive industries like manufacturing, airlines, and telecommunications, free cash flow, which subtracts capital expenditures, is often a more honest measure of financial health.
It’s Not a GAAP Measure
Because EBITDA isn’t defined under Generally Accepted Accounting Principles, companies have latitude in how they calculate it. Public companies that disclose EBITDA must reconcile it to the most comparable GAAP measure, typically net income, under SEC Regulation G.5eCFR. 17 CFR Part 244 – Regulation G The SEC specifically exempts EBITDA and EBIT from certain non-GAAP prohibitions given their widespread use, but requires that any modified version be clearly distinguished from standard EBITDA.6U.S. Securities and Exchange Commission. Conditions for Use of Non-GAAP Financial Measures
It Can Mask Cash Flow Problems
A company can post a strong EBITDA margin while struggling to make debt payments, fund operations, or pay suppliers on time. EBITDA describes earning power in a pre-obligation sense. It doesn’t tell you whether the business can actually cover its bills. If the company carries significant debt, the interest payments EBITDA strips away are very real cash obligations.
None of that makes the calculation useless. EBITDA margin is still the standard starting point for comparing operational profitability across companies with different capital structures, tax situations, and asset bases. Pair it with free cash flow and net income trends when you need a view that accounts for what EBITDA deliberately leaves out.
