What Is EBITDA? A Plain-English Guide for Founders
EBITDA explained without the jargon: what it measures, how to calculate it, why investors ask for it, and the three situations where it will actively mislead you.
The short answer
EBITDA stands for Earnings Before Interest, Taxes, Depreciation and Amortisation.
It is an attempt to answer one question: how much money does this business generate from actually operating, before we account for how it is financed, where it is taxed, and how its past asset purchases are being written down?
That is genuinely useful. It is also easy to misuse, and founders get caught out by it more often than by almost any other metric.
How to calculate it
There are two routes to the same number.
From operating profit:
EBITDA = Operating profit + Depreciation + Amortisation
From net profit:
EBITDA = Net profit + Interest + Taxes + Depreciation + Amortisation
Worked example. A company reports:
| Line | Amount |
|---|---|
| Revenue | ₹4,00,00,000 |
| Cost of goods sold | ₹1,60,00,000 |
| Operating expenses | ₹1,80,00,000 |
| Depreciation | ₹20,00,000 |
| Interest on debt | ₹12,00,000 |
| Tax | ₹8,00,000 |
Operating profit is ₹4,00,00,000 − ₹1,60,00,000 − ₹1,80,00,000 − ₹20,00,000 = ₹40,00,000.
Net profit is ₹40,00,000 − ₹12,00,000 − ₹8,00,000 = ₹20,00,000.
EBITDA is ₹40,00,000 + ₹20,00,000 (depreciation) = ₹60,00,000.
Three different numbers describing the same quarter. This is why people specify which one they mean.
What each excluded item is doing there
The four exclusions are not arbitrary. Each one strips out a factor that varies for reasons unrelated to how well the business operates.
Interest depends on how the company is financed. Two identical businesses, one funded by equity and one carrying debt, will show different net profit purely because of their capital structure. Removing interest lets you compare the operations.
Taxes depend on jurisdiction, entity structure, and whatever exemptions apply. A DPIIT-recognised startup claiming a tax holiday is not operationally better than an identical company that is not - it is just taxed differently.
Depreciation spreads the cost of a physical asset across its useful life. It is a real economic cost, but it reflects a purchase decision made in the past, and the accounting policy chosen to represent it.
Amortisation does the same for intangibles - acquired software, patents, goodwill.
Add those back and you get something closer to a comparison of operating performance across companies with different financing, tax positions and asset histories.
Why investors ask for it
Three reasons, in rough order of how often they apply.
Comparability. A fund looking at six companies in a sector wants to compare like with like. EBITDA neutralises the differences that come from financing and tax rather than from running the business.
Valuation. Established businesses are frequently valued on an EBITDA multiple. If comparable companies in your sector trade at 10× EBITDA, your EBITDA becomes the anchor for the conversation. This is standard in mature sectors and much less common in early-stage venture.
Debt capacity. Lenders care about EBITDA because it approximates the cash available to service debt. Loan covenants are frequently written as a ratio of debt to EBITDA.
The three ways EBITDA will mislead you
This is the part most explanations skip.
It is not cash flow
EBITDA ignores three things that consume real money:
- Working capital. If your receivables grow because customers are slow to pay, EBITDA does not notice. Your bank balance does.
- Capital expenditure. EBITDA adds depreciation back, which effectively pretends the asset was free. If your business needs to keep buying equipment, that is a permanent cash cost EBITDA hides.
- Debt repayment. Principal repayments never appear in EBITDA at all.
A business with strong EBITDA and negative operating cash flow is not a paradox. It is common, and it is how companies with good-looking numbers run out of money.
It flatters capital-intensive businesses
The more a business depends on physical assets, the more EBITDA overstates its economics. Manufacturing, hardware, and anything involving heavy infrastructure will always look better on EBITDA than on net profit, because the depreciation being added back represents a cost that genuinely recurs.
Charlie Munger's objection to the metric was that "earnings before interest, taxes, depreciation and amortisation" is close to "earnings before the costs of doing business."
It can be quietly redefined
EBITDA is not a defined term under any accounting standard. That means "adjusted EBITDA" is whatever the person presenting it says it is.
You will see EBITDA adjusted to exclude one-off restructuring costs, share-based compensation, or "non-recurring" expenses that recur annually. Sometimes those adjustments are reasonable. Sometimes they are how a loss becomes a profit.
When you receive an adjusted EBITDA figure, ask what was adjusted. When you present one, expect to be asked.
What early-stage founders should track instead
If you are pre-revenue or early-revenue, EBITDA is almost certainly negative and will stay that way while you are deliberately spending to grow. Reporting it as a headline tells an investor nothing they did not already assume.
More useful at that stage:
- Gross margin. Revenue minus direct cost of delivery, as a percentage. This tells you whether the underlying unit economics work at all.
- Burn rate. Net cash leaving the business each month.
- Runway. Cash in bank divided by monthly burn. The number of months before you need more money.
- CAC and payback period. What it costs to acquire a customer, and how long they take to repay it.
These are the numbers that determine whether you survive long enough for EBITDA to become interesting.
When EBITDA does start to matter
Somewhere around the point where you are having Series B or later conversations, or talking to a lender, or approaching profitability, EBITDA becomes part of the language whether you find it useful or not.
At that stage you want to be able to do three things: state your EBITDA accurately, explain the gap between EBITDA and operating cash flow, and defend any adjustment you have made. Founders who can do all three are taken more seriously than founders who quote the number without understanding it.
The one-line summary
EBITDA is a reasonable proxy for operating performance and a poor proxy for cash. Use it to compare businesses; never use it to work out whether you can pay salaries next month.
Frequently asked questions
- Is EBITDA the same as profit?
- No. EBITDA deliberately excludes interest, tax, depreciation and amortisation, so it is not what you keep. Net profit is what remains after all of those. A company can show positive EBITDA and still make a net loss.
- Is EBITDA the same as cash flow?
- No, and treating it as such is the most common EBITDA mistake. EBITDA ignores changes in working capital, loan repayments and capital expenditure - all of which consume real cash. A business can have healthy EBITDA and still run out of money.
- Do early-stage startups need to report EBITDA?
- Usually not as a headline metric. Most pre-revenue and early-revenue startups have negative EBITDA by design because they are spending to grow. Gross margin, burn rate and runway are far more informative at that stage.
