You open a business news website and see a line like this: “EBITDA margin fell from 35.3% to 8.2%.” Sounds serious. But what does it actually mean? And why do two websites sometimes show two very different margins for the same company?
This guide explains EBITDA margin in plain language. No finance degree needed. We start with a simple tea-stall example, learn the formula, and then check a real case using the official results: Natco Pharma’s December 2024 quarter, where profit fell sharply and the EBITDA margin shrank by about three-fourths.
Quick answer: EBITDA margin tells you how much operating profit a company keeps from every ₹100 of sales, before paying interest and tax and before counting wear and tear on machines. A higher margin usually means a healthier, more efficient business.
What Is EBITDA Margin? A Tea-Stall Example
Imagine you run a tea stall. In one month you sell tea and snacks worth ₹1,00,000. This is your revenue (also called sales).
To run the stall you spend on milk, sugar, tea leaves, gas, your helper’s salary and shop rent. Say this adds up to ₹70,000.
What is left is ₹1,00,000 − ₹70,000 = ₹30,000. This is the profit your stall earned from its day-to-day work. In finance language, this is the EBITDA.
Now the margin: ₹30,000 ÷ ₹1,00,000 × 100 = 30%. So your EBITDA margin is 30%. It means that out of every ₹100 you collect from customers, ₹30 is left after paying the running costs of the business.
One more thing. Suppose you also earned ₹5,000 as interest on your savings in the bank. That money did not come from selling tea. Finance people call it other income. Most analysts keep it out of EBITDA, so the margin still tells you about the tea business only. Remember this point. It becomes important in the Natco example.
In one line: EBITDA margin = how much of each rupee of sales is left after the everyday costs of running the business.
EBITDA Full Form: What Each Letter Means
EBITDA is pronounced “ee-bit-dah”. It looks scary, but it is just a list of things we leave out before counting profit.
| Letter | Stands for | Meaning in simple words |
|---|---|---|
| E | Earnings | The profit the business makes |
| B | Before | We count the profit before taking out the items below |
| I | Interest | The interest paid on loans the company has taken |
| T | Taxes | Income tax paid to the government |
| D | Depreciation | The slow loss in value of machines, buildings and vehicles over the years |
| A | Amortisation | The same idea as depreciation, but for things you cannot touch, such as patents and software |
Why leave these out? Because interest depends on how the company is funded, tax depends on rules, and depreciation is an accounting entry, not cash going out today. By removing them, EBITDA shows how well the core business performs.
EBITDA Margin Formula
EBITDA Margin (%) = (EBITDA ÷ Revenue) × 100
Here, EBITDA is the operating profit of the company (before the items in the table above), and Revenue is the total sales for the same period. Always use the same period for both, for example the same quarter.
Why Does EBITDA Margin Matter?
EBITDA margin is one of the first numbers analysts look at, for good reasons:
- It shows efficiency. A high margin means the company controls its costs well compared to its sales.
- It helps compare companies. A small company and a large company can be compared fairly because the margin is a percentage, not a rupee amount.
- It gives a cushion. Interest, tax and depreciation still have to be paid from this operating profit. A fat margin makes this easy; a thin margin makes it hard.
- It shows the strength of the products. If a company sells high-profit products, the margin goes up. If those sales shrink, the margin falls quickly.
- It affects how the market sees the company. Steady or improving margins build investor confidence. A sudden crash raises questions and can pull the share price down.
- It gives room to grow. Higher margins leave more cash for research, new factories and repaying debt.
Real Example: Natco Pharma’s December 2024 Quarter
Let us now see all of this in a real company. Natco Pharma is a Hyderabad-based pharmaceutical company. It makes medicines (including cancer medicines) and the raw materials used in medicines (called APIs), and also has a small crop-protection business. It sells in India and in many other countries. Exports of formulations, which means ready-to-use medicines sold abroad, are a major source of its earnings.
The numbers below come from Natco’s official results and press release, announced on 12 February 2025 for the quarter ended 31 December 2024. We convert the amounts into ₹ crore because that is how most investors read them.
Quick note on dates: Indian companies follow the April–March financial year. “Q3 FY2025” means October–December 2024. “Q3 FY2024” means October–December 2023. So we are comparing the same quarter of two consecutive years.
Which “revenue” are we using? Natco’s press release headline shows total revenue of ₹651.1 crore (against ₹795.6 crore a year ago). That total also includes other income. To calculate a margin of the core business, we use revenue from operations: ₹474.8 crore against ₹758.6 crore.
Natco Pharma: Q3 FY2024 vs Q3 FY2025 at a glance
All amounts are in ₹ crore, except percentages.
| What we are looking at | Q3 FY2024 (Dec 2023) | Q3 FY2025 (Dec 2024) | Change |
|---|---|---|---|
| Revenue from operations | 758.6 | 474.8 | −37.4% |
| Other income | 37.0 | 176.3 | About 4.8 times |
| EBITDA (without other income)* | 268.1 | 38.8 | −85.5% |
| EBITDA margin | 35.3% | 8.2% | Down about 27 percentage points |
| Net profit (profit for the period) | 212.7 | 132.4 | −37.8% |
*Natco’s results do not show a separate EBITDA line. We calculated it from the reported numbers (shown step by step below). Net profit attributable to the company’s owners is ₹133.0 crore; the small difference belongs to minority shareholders in a subsidiary.
Where did the revenue come from?
The press release splits the quarter’s income like this (₹ crore):
| Source of income | Q3 FY2024 | Q3 FY2025 | Change |
|---|---|---|---|
| Formulations export (incl. profit share and subsidiaries) | 605.6 | 285.8 | −52.8% |
| Domestic formulations (India) | 99.4 | 96.1 | −3.3% |
| API (raw material for medicines) | 46.3 | 66.6 | +43.8% |
| Crop health sciences | 14.1 | 15.1 | +7.1% |
| Other operating and non-operating income | 30.2 | 187.5 | About 6.2 times |
| Total as shown in the press release | 795.6 | 651.1 | −18.2% |
Step 1: Export sales fell by more than half
Sales of formulations abroad dropped from ₹605.6 crore to ₹285.8 crore, a fall of 52.8%. Natco’s press release says the contribution from the export formulation business was lower this quarter. It does not name a product. Natco’s US business is closely linked with its generic version of Revlimid, a high-margin cancer medicine, so investors watch it very closely. But the filing gives no product-wise numbers, so we cannot say how much of the fall came from one medicine.
In rupees, the export fall was about ₹320 crore. That is even larger than the fall in revenue from operations (about ₹284 crore), because a few other areas, like API sales, grew a little and softened the blow.
Step 2: Revenue from operations fell by 37.4%
With exports down, revenue from operations dropped from ₹758.6 crore to ₹474.8 crore. Sales in India also slipped slightly, so there was no big domestic gain to fill the gap.
Step 3: Costs did not fall as fast as sales
This is the heart of the story. To find the costs that matter for EBITDA, we take the total expenses and remove depreciation and interest (finance costs). Those are the “D” and “I” of EBITDA. What remains are the operating costs:
- Operating costs fell from ₹490.5 crore to ₹436.0 crore, only about 11% lower.
- Revenue from operations fell 37.4% in the same period.
Why did costs fall so little? Many costs do not shrink just because sales fall. Employee costs actually rose about 16% (from ₹121.9 crore to ₹141.6 crore), and other expenses rose about 2.5% (from ₹206.4 crore to ₹211.6 crore). Only the cost of materials went down clearly (about 21%, from ₹92.2 crore to ₹72.7 crore), which makes sense when fewer medicines are sold.
Think of the tea stall again. If half your customers disappear, you still pay the same rent and the same helper’s salary. Your profit shrinks much faster than your sales.
Step 4: EBITDA collapsed, and so did the margin
Now we can work out EBITDA ourselves, the same way we did for the tea stall: sales minus operating costs.
| ₹ crore | Q3 FY2024 | Q3 FY2025 |
|---|---|---|
| Revenue from operations | 758.6 | 474.8 |
| Less: operating costs (total expenses minus depreciation and finance costs) | 490.5 | 436.0 |
| EBITDA | 268.1 | 38.8 |
| EBITDA margin (EBITDA ÷ revenue × 100) | 268.1 ÷ 758.6 × 100 = 35.3% | 38.8 ÷ 474.8 × 100 = 8.2% |
EBITDA fell by 85.5%. In plain words: last year, from every ₹100 of sales, Natco kept about ₹35.30 as operating profit. In this quarter, it kept only about ₹8.20. That is the meaning of a margin falling from 35.3% to 8.2%.
Step 5: Why did net profit fall only 37.8% when EBITDA fell 85.5%?
This is where many beginners get confused, and where the “other income” idea from the tea stall comes back. Let us walk from EBITDA down to net profit, just like the letters in EBITDA suggest:
| ₹ crore | Q3 FY2024 | Q3 FY2025 |
|---|---|---|
| EBITDA | 268.1 | 38.8 |
| Add: other income | 37.0 | 176.3 |
| Less: depreciation (wear and tear) | 44.2 | 47.0 |
| Less: interest on loans (finance costs) | 4.6 | 4.4 |
| Profit before tax | 256.3 | 163.7 |
| Less: tax | 43.6 | 31.3 |
| Net profit | 212.7 | 132.4 |
Look at the “other income” row. It jumped from ₹37.0 crore to ₹176.3 crore. That extra money cushioned the fall and is why net profit dropped much less than EBITDA. The summary results do not explain what this income is made of. Income of this kind often comes from interest on investments or currency gains, so check the notes in the full results if you want to know.
There is an important lesson here. Without other income, Natco’s core business would have shown a small loss before tax of about ₹12.6 crore in this quarter (revenue from operations ₹474.8 crore minus total expenses ₹487.4 crore). The thin 8.2% EBITDA margin was the first warning sign of this.
Same quarter, two different margins. Some news reports and websites add other income to EBITDA. If we do that, Natco’s EBITDA becomes ₹215.1 crore (38.8 + 176.3) on total income of ₹651.1 crore, which gives a margin of about 33.0%, against about 38.3% a year ago. That looks like a mild dip, not a crash! Neither method is “wrong”. They simply measure different things. This is why you should always check how a number is defined before you compare it.
What Can We Learn From the Natco Example?
- Depending on one big area is risky. Export formulations fell by more than half, and that alone pulled down revenue, EBITDA and the margin.
- Margins tell the story faster than sales. Revenue from operations fell 37%, but EBITDA fell 85%. The margin showed how deep the damage was in the core business.
- Fixed costs make falls sharper. Costs that do not shrink with sales, such as salaries, squeeze the margin when revenue drops.
- Check what is inside the profit. Net profit looked less bad than the core business because of a large jump in other income. Always ask where the profit came from.
- Check how EBITDA is defined. With or without other income, the same quarter can show an 8.2% margin or a 33.0% margin.
- One quarter is not the whole picture. Natco’s nine-month net profit for April–December 2024 was ₹1,477.4 crore, about 47% higher than ₹1,002.0 crore a year earlier. In the previous quarter (July–September 2024) revenue from operations was ₹1,371.1 crore, and the same calculation gives an EBITDA margin of about 59%. Sales in this business can be lumpy, so look at several quarters together. The company’s press release said it expected healthy growth in the coming quarters. Since we are now in October 2026, check the latest results to see what actually happened.
How to Calculate EBITDA Margin: 3 Easy Steps
- Find the EBITDA. Look in the company’s quarterly results or investor presentation. Many stock websites show it as “Operating Profit” or “EBITDA”.
- Find the revenue. Use “Revenue from operations” or “Sales” for the same period.
- Divide and multiply by 100. EBITDA ÷ Revenue × 100 gives the margin in percentage. For Natco: 38.8 ÷ 474.8 × 100 = 8.2%.
If the results show no EBITDA line (as with Natco), you can work it out: Profit before tax + finance costs + depreciation and amortisation − other income. For Natco’s Dec 2024 quarter: 163.7 + 4.4 + 47.0 − 176.3 = ₹38.8 crore.
Tip: On many Indian stock websites, the “OPM %” (operating profit margin) is very close to the EBITDA margin and is already calculated for you. Check whether the site includes other income or not.
What Is a Good EBITDA Margin?
There is no single “good” number. It depends on the industry. A software company or a pharma company with specialised products can earn high margins, while a retail shop or an airline usually works with much thinner margins. So:
- Compare a company with others in the same industry.
- Compare a company with its own past quarters and years. A steady or rising margin is a good sign; a sharp fall needs an explanation.
EBITDA Margin vs Net Profit Margin
| EBITDA margin | Net profit margin | |
|---|---|---|
| What it shows | Profit from core operations | Final profit left for shareholders |
| Interest counted? | No | Yes |
| Tax counted? | No | Yes |
| Depreciation counted? | No | Yes |
| Other income counted? | Usually no (depends on who calculates it) | Yes |
| Best used for | Judging how efficiently the business runs | Judging final profitability |
Both are useful. Using them together gives a fuller picture than either one alone. Natco’s quarter showed why: the EBITDA margin warned about the core business, while net profit was cushioned by other income.
Limits of EBITDA Margin: What It Does Not Tell You
EBITDA margin is helpful, but it is not perfect. Keep these points in mind:
- It ignores debt. A company can show a good EBITDA margin and still struggle if its interest payments are very high.
- It ignores the cost of machines and equipment. Companies that need to keep buying costly machinery may look better on EBITDA than they really are.
- It is not an official accounting figure, so two companies or websites may calculate it differently, as we saw with other income.
- It says nothing about cash flow or how well the company uses the money invested in it.
For that last point, ratios like ROE and ROCE help. They show how much profit a company earns on the money invested in it. If you want to learn them in simple language, read our guide on ROE vs ROCE: which ratio to use. Smart investors look at EBITDA margin along with net profit, debt, cash flow, ROE and ROCE.
Key Takeaways
- EBITDA margin = (EBITDA ÷ Revenue) × 100. It shows how much operating profit a company keeps from each ₹100 of sales.
- A higher margin usually means better efficiency and a stronger cushion against interest, tax and other costs.
- In Q3 FY2025, Natco Pharma’s EBITDA margin (without other income) fell from 35.3% to 8.2%. Revenue from operations fell 37.4% while operating costs fell only about 11%.
- Net profit fell by a smaller 37.8% because other income jumped from ₹37.0 crore to ₹176.3 crore.
- Always check how EBITDA is defined, and compare margins within the same industry and over time.

Frequently Asked Questions (FAQs)
What is EBITDA margin in simple words?
It tells you how many rupees of operating profit a company keeps from every ₹100 of sales, before interest, tax, depreciation and amortisation.
What is the EBITDA margin formula?
EBITDA margin (%) = (EBITDA ÷ Revenue) × 100.
Is a high EBITDA margin always good?
Usually yes, but not always. A high margin can still come with heavy debt or large machinery costs that EBITDA does not show. Check other numbers too.
What is the difference between EBITDA and net profit?
EBITDA is profit from core operations before interest, tax, depreciation and amortisation. Net profit is what remains after all of these are paid, and it also includes other income.
Does EBITDA include other income?
It depends on who calculates it. Many analysts leave other income out so that EBITDA shows only the core business. Some websites and brokers include it, which can give a very different margin.
Why did Natco Pharma’s profit fall in Q3 FY2025?
Mainly because export formulation sales fell by about 53%. Revenue from operations dropped 37.4% while operating costs fell only about 11%, so net profit fell 37.8% to ₹132.4 crore, helped by a jump in other income.
What is a good EBITDA margin?
It depends on the industry. Compare a company with its peers and with its own history instead of looking for one fixed number.
Can EBITDA margin be negative?
Yes. If a company’s operating costs are higher than its revenue, EBITDA turns negative and so does the margin.
