EBITDA: Meaning, Formula and How to Calculate It

EBITDA stands for earnings before interest, tax, depreciation and amortisation. It is a measure of what a business earns from its core operations, before the effects of how it is financed, where it is taxed, and how it accounts for its assets. Strip those three things away and you are left with a number that lets you compare two businesses on operating performance alone.

That is also why it is the most abused metric in finance. Every one of the things it removes is a real cost that someone eventually pays. This guide covers the formulas, a worked Indian example, what a good EBITDA margin looks like by sector, and the specific ways the number gets manipulated, because the last part is what a buyer will test. It sits under the reporting discipline our fractional CFO engagements start with.

The two EBITDA formulas

There are two routes to the same number, and which one you use depends on where you start.

Top-down: EBITDA = Revenue minus cost of goods sold minus operating expenses (excluding depreciation and amortisation)

Bottom-up: EBITDA = Net profit + interest + tax + depreciation + amortisation

The bottom-up version is the one to use when you are reading someone else’s accounts, because net profit, interest, tax and depreciation are all disclosed. The top-down version is the one to use inside your own business, because it shows you which line to act on. If the two do not reconcile, something is misclassified, and finding out what is usually worth the hour it takes.

How to calculate EBITDA: a worked example

Take a manufacturing business doing ₹40 crore of revenue.

Check the bottom-up formula against it: ₹1.27 crore net profit, plus ₹43 lakh tax, plus ₹90 lakh interest, plus ₹1.4 crore depreciation and amortisation, gives ₹4 crore. The two routes agree.

Now read the gap. EBITDA is ₹4 crore and net profit is ₹1.27 crore. Nearly ₹2.75 crore disappears into depreciation, interest and tax. For a capital-intensive, leveraged business that gap is permanent and structural, not an accounting artefact. Anyone quoting the ₹4 crore as “what the business makes” is describing a company that does not exist.

EBITDA margin, and what counts as good

EBITDA margin = (EBITDA divided by revenue) x 100

There is no universal good number, only sector norms. Broad Indian ranges for a business at scale:

Note the last row carefully. A high EBITDA margin in a capital-heavy business is not a sign of a better business than a distributor at 5 percent; it reflects that a large part of its cost base sits below the EBITDA line as depreciation. Comparing EBITDA margins across sectors with different capital intensity is one of the most common analytical mistakes founders make. Compare within a sector, and against your own trailing twelve months, which is what a properly built monthly MIS pack gives you.

Why buyers and lenders use EBITDA

The measure persists despite its flaws because it solves a real problem: comparability.

• It removes capital structure. Two identical businesses, one debt-funded and one equity-funded, report very different net profits. Their EBITDA is the same, so an acquirer can compare the underlying operations before deciding how to finance the deal.
• It removes tax jurisdiction and accounting policy. Depreciation rates and tax positions differ across companies and countries. EBITDA neutralises them.
• It is the basis of valuation multiples. Most private company transactions in India are priced as a multiple of EBITDA. A change of one turn on ₹4 crore of it is ₹4 crore of enterprise value, which is why earnings quality gets scrutinised so hard. See enterprise value vs equity value for how that converts into what shareholders actually receive.
• It anchors debt covenants. Lenders size facilities on multiples of it and monitor net debt cover. Breaching that ratio can trigger a default independent of whether the business is paying its bills.

What EBITDA hides, and how it gets manipulated

Charlie Munger famously refused to take the measure seriously, arguing that anyone quoting it should mentally substitute a far blunter phrase, on the grounds that depreciation is a real cost being wished away. He was overstating it to make a point that is essentially correct.

• Depreciation is a real cost, deferred. A logistics business with a fleet must replace that fleet. Excluding depreciation does not make the trucks last longer. For any asset-heavy business, the measure systematically overstates economic earnings.
• Interest is a real cost, and it is contractual. A leveraged business has to service its debt out of the same cash EBITDA describes.
• It ignores working capital entirely. A business can grow EBITDA while consuming cash, if receivables and inventory grow faster than profit. This is the single most common way a profitable Indian SME runs out of money. See working capital management.
• It ignores capex too. Two businesses with identical EBITDA can have wildly different cash generation if one spends 2 percent of revenue on capex and the other spends 12 percent. Free cash flow is the honest counterpart, and capex vs revenue expenditure explains why capitalising a cost removes it from EBITDA altogether.
• Adjusted EBITDA is where the real games happen. “Adjusted” or “normalised” EBITDA adds back items management deems one-off. Some of those adjustments are legitimate; many are recurring costs relabelled. Every add-back should be challenged individually.

This is exactly what quality of earnings analysis exists to test, and it is a standard workstream in financial due diligence. In practice a buyer will rebuild your EBITDA from the general ledger and reject the add-backs they disagree with, and each rejected add-back costs you the multiple. A founder who has been disciplined about what goes into adjusted EBITDA all along negotiates from a much stronger position than one who assembled a flattering number for the deal.

The cash conversion test

The single most useful diagnostic a founder can run takes about two minutes. Take operating cash flow from the cash flow statement and divide it by the operating earnings figure for the same period.

Cash conversion = Operating cash flow divided by EBITDA

A business converting above roughly 80 percent is turning its reported operating performance into money. Between 60 and 80 percent is common in a growing company, because expansion absorbs working capital. Persistently below 60 percent means the earnings are not becoming cash, and the difference is sitting in receivables, inventory or both.

The reason this matters more than any margin benchmark is that it cannot be argued with. Margins depend on classification choices, add-backs and accounting policy. The bank balance does not. A founder who can show three years of consistent, high conversion has demonstrated something about the quality of the business that no adjusted figure can claim on its own, and a founder whose conversion has been drifting downward for six quarters has a working capital problem that will surface in diligence whether or not they raise it first.

Where conversion is weak, the fix is almost never in the profit and loss account. It is in collections discipline, payment terms and inventory, which is the subject of accounts payable vs accounts receivable and of the wider cash conversion cycle.

Common add-backs, and whether they survive scrutiny

How to use EBITDA well

• Never read it alone. Put it, net profit and operating cash flow on the same page. If the headline is rising and operating cash flow is not, the difference is working capital and it is the more urgent problem.
• Track the EBITDA-to-cash conversion rate (operating cash flow divided by EBITDA). Consistently below about 70 percent means the earnings are not turning into money.
• Keep an add-back register from day one, with the evidence attached. Reconstructing it under deal pressure is where credibility gets lost.
• For capital-heavy businesses, lead with EBIT or free cash flow instead. EBITDA flatters you in a way sophisticated buyers will discount anyway.
• Watch your net debt cover if you carry debt. It is the covenant most likely to bind first.

The bottom line on EBITDA

EBITDA is the right tool for comparing operating performance between businesses and the wrong tool for deciding what a business earns. Use it to benchmark, to price a deal and to size debt. Do not use it to reassure yourself that a capital-intensive, leveraged company is more profitable than it is. The gap between EBITDA and cash in the bank is where most of the interesting questions about a business actually live.
