What EBITDA means, in plain English
EBITDA is Earnings Before Interest, Taxes, Depreciation, and Amortization. You take the profit a business reports, then add back four expenses that have little to do with how well the operation itself runs day to day.
Each add-back removes one source of noise:
- Interest depends on how the business is financed. Two identical shops, one bought with cash and one with a loan, report different net income for the same operating performance.
- Taxes depend on jurisdiction, entity type, and past losses carried forward, none of which say anything about whether the operation makes money.
- Depreciation is an accounting allocation of money already spent on equipment, vehicles, or buildings. It varies with asset age and the depreciation schedule chosen, not with this year’s performance.
- Amortization is the same idea applied to intangible assets, most often goodwill and customer lists picked up in a past acquisition.
So the question EBITDA answers is: how much does the core operation earn, regardless of who owns it, how they financed it, and what accounting history it carries? That framing is exactly why it dominates lending decisions and business sales, and also exactly where its blind spots come from.
The EBITDA formula (two ways to get there)
There are two standard routes to EBITDA, and they must arrive at the same number. Which one you use just depends on where you start on the income statement.
- Top-down (from the bottom line): EBITDA = net income + interest + taxes + depreciation + amortization. Start with reported profit and add back the four items.
- Bottom-up (from operating income): EBITDA = operating income + depreciation + amortization. Operating income (EBIT) already excludes interest and taxes, so only D&A needs to come back.
The bottom-up route is usually faster if you have a clean income statement, because operating income is printed right on it. The top-down route is handy when you only have a tax return or a bottom-line profit figure. If the two routes disagree, something below the operating line (a one-time gain, other income, or a misclassified expense) is polluting one of them, which is itself useful to know.
Worked example: from $2,000,000 in revenue to EBITDA
Here is the full income statement for a sample services company doing $2,000,000 in revenue, carrying some equipment and a business loan:
| Line item | Amount |
|---|---|
| Revenue | $2,000,000 |
| Cost of goods sold | $800,000 |
| Gross profit | $1,200,000 |
| Operating expenses (salaries, rent, marketing) | $700,000 |
| Depreciation | $90,000 |
| Amortization | $30,000 |
| Operating income (EBIT) | $380,000 |
| Interest expense | $60,000 |
| Pre-tax income | $320,000 |
| Taxes (25%) | $80,000 |
| Net income | $240,000 |
Now build EBITDA both ways and watch them reconcile:
| Step | Top-down | Bottom-up |
|---|---|---|
| Starting point | Net income: $240,000 | Operating income: $380,000 |
| Add back interest | $60,000 | Already excluded |
| Add back taxes | $80,000 | Already excluded |
| Add back depreciation | $90,000 | $90,000 |
| Add back amortization | $30,000 | $30,000 |
| EBITDA | $500,000 | $500,000 |
Both routes land on $500,000. Notice the gap between that and the $240,000 of net income: more than half the difference is interest and taxes, and the rest is D&A. A buyer who plans to pay cash and run the company in a different tax situation cares about the $500,000, not the $240,000.
EBITDA margin: the percentage version
EBITDA margin = EBITDA ÷ revenue. Our sample company runs $500,000 of EBITDA on $2,000,000 of revenue, an EBITDA margin of 25%. The margin makes companies of different sizes comparable: a 25% margin means 25 cents of every revenue dollar survive as operating earnings before financing and accounting charges.
What counts as "good" depends almost entirely on the business model:
| Business type | Typical EBITDA margin | Why |
|---|---|---|
| Grocery, distribution, low-margin retail | 2% to 8% | High volume, thin markup, intense price competition |
| Restaurants, general retail | 5% to 15% | Labor and rent absorb much of the gross margin |
| Professional services, agencies | 10% to 25% | People-driven costs, limited leverage on scale |
| Manufacturing | 10% to 25% | Varies with automation and pricing power |
| Software and SaaS (at scale) | 20% to 40%+ | Low marginal cost per additional customer |
Compare against your own industry, not the table averages of another one. A 9% EBITDA margin is strong for a grocery distributor and alarming for a software business. To see where your own gross, operating, and net margins sit from your real numbers, run them through the profit margin calculator.
Why lenders and buyers price everything off EBITDA
EBITDA is the working language of debt and deals for one reason: it approximates the earnings power available to whoever ends up owning or lending to the business, before the current owner’s financing and tax choices.
- Debt covenants: business loans routinely cap leverage at a multiple of EBITDA (for example, total debt below 3x EBITDA) and require a minimum coverage ratio of EBITDA to interest or debt service. Trip the covenant and the loan can be called or repriced.
- EV/EBITDA multiples: small and mid-sized businesses are commonly valued as a multiple of EBITDA. A company producing $500,000 of EBITDA valued at 4x to 6x would fetch roughly $2,000,000 to $3,000,000 of enterprise value. The multiple itself moves with growth, industry, and customer concentration.
- Comparability across capital structures: because interest is added back, a debt-funded competitor and a cash-rich one can be lined up side by side. Net income cannot do that.
One important exception: high-growth software businesses often run near zero EBITDA on purpose, reinvesting everything in growth, so acquirers price them on revenue multiples adjusted for growth and retention instead. If that describes your business, the SaaS valuation calculator uses the revenue-multiple framing buyers actually apply.
The honest criticism: what EBITDA hides
Warren Buffett put the case bluntly in his 2000 letter to Berkshire Hathaway shareholders: "References to EBITDA make us shudder", he wrote, asking whether "management think[s] the tooth fairy pays for capital expenditures?" His point was not rhetorical flourish. The expenses EBITDA adds back are real, and three of its blind spots bite hardest:
- Capex blindness. Depreciation is an accounting entry, but the trucks, machines, and servers it represents wear out and must be replaced with real cash. A trucking company can show fat EBITDA for years while its fleet quietly ages toward a replacement bill EBITDA never mentioned.
- Working-capital blindness. EBITDA counts a sale when it is booked, not when the customer pays. A business growing fast on 60-day invoice terms can post record EBITDA while its bank account drains. Only a cash flow view catches that; the cash flow calculator shows the difference on your own numbers.
- It is not GAAP. No accounting standard defines EBITDA, so every company computes it slightly differently, and "adjusted EBITDA" invites abuse. Add-backs for "one-time" legal costs that recur every year, "normalized" owner salaries set below market, and restructuring charges that never end can inflate the figure a seller presents. In a deal, rebuild EBITDA yourself from the raw financials and challenge every add-back.
None of this makes EBITDA useless. It makes it a starting point that always needs a second question: what does this business have to spend on assets and working capital to keep its EBITDA coming?
EBITDA vs operating income vs net income vs free cash flow
The four headline profit metrics answer four different questions. Confusing them is how owners overestimate what they can safely pull out of the business.
| Metric | Includes | Ignores | Best used for |
|---|---|---|---|
| EBITDA | Revenue, COGS, operating expenses | Interest, taxes, D&A, capex, working capital | Comparing operations across companies; loan covenants; valuation multiples |
| Operating income (EBIT) | Everything above, plus D&A | Interest, taxes, capex timing, working capital | Judging operating performance while still charging for asset wear |
| Net income | All expenses: interest, taxes, D&A | Cash timing of capex and working capital | The legal bottom line; per-share earnings; tax reporting |
| Free cash flow | Actual cash in and out, including capex and working capital | Non-cash accounting entries | What the owner can actually take out or reinvest; solvency |
In our worked example the spread is stark: $500,000 of EBITDA, $380,000 of operating income, $240,000 of net income (a 12% net margin). Free cash flow would sit somewhere below EBITDA depending on how much of the $120,000 in D&A must actually be re-spent on replacement assets each year. A useful habit: quote EBITDA to your lender, but budget your own life on free cash flow.
When EBITDA is the wrong lens
Two situations reliably make EBITDA misleading, and both come straight from what it excludes.
- Capital-intensive businesses. Trucking, manufacturing, airlines, gyms, restaurants with expensive fit-outs: anywhere depreciation approximates a real, recurring replacement cost, adding it back overstates sustainable earnings. For these businesses, EBITDA minus maintenance capex (or plain EBIT) is a far more honest measure.
- Heavily indebted companies. Interest may be a financing choice in theory, but for a business carrying serious debt it is a non-negotiable monthly cash outflow. Pretending it away with EBITDA is how over-leveraged companies look healthy right up until they miss a payment. Look at EBITDA relative to total debt service, not EBITDA alone.
The pattern behind both: EBITDA works best when the add-backs are genuinely discretionary or genuinely non-cash, and worst when they are recurring cash obligations wearing accounting labels. Asset-light, modestly-leveraged service businesses fit the first description. If your depreciation and interest lines are large relative to operating income, reach for operating income and free cash flow instead.
