DuPont Analysis Calculator | ROE Decomposition
💡 Key Tips
- Two companies can post an identical 20% ROE for opposite reasons. One earns it on fat margins, the other on borrowed money. DuPont is what separates them.
- FMCG and pharma typically show high margin with low turnover. Retail and distribution show thin margin with high turnover. Neither is better — but the risks differ.
- An equity multiplier above 3x means two-thirds of the balance sheet is funded by liabilities. That flatters ROE in good years and destroys it in bad ones.
- Compare the 3-step and 5-step views. If ROE is holding up only because of the interest burden ratio, the business is leaning on cheap debt rather than operations.
- Run the decomposition across five years. Watching which of the three levers moved tells you far more than the headline ROE trend.
⚠️ Things To Watch
- ROE flatters companies with small equity bases. A firm that has bought back heavily or carries accumulated losses can show a spectacular ROE on a weak business.
- Use average equity and average assets across the year if the balance sheet moved a lot. Year-end figures distort the ratios after a large fundraise or acquisition.
- Not meaningful for banks and NBFCs — leverage is their business model, so the equity multiplier tells you nothing useful about risk.
- A negative equity base makes ROE mathematically meaningless. If net worth is negative, stop and read the balance sheet instead.
- One-off items — asset sales, tax write-backs, exceptional provisions — distort net margin badly. Normalise before comparing years.

📐 DuPont Decomposition Explained
1. The 3-step DuPont identity
2. Why it works — the terms cancel
3. The 5-step version — splitting margin into three
4. Return on Assets and the leverage contribution
DuPont analysis breaks Return on Equity into its underlying drivers — profit margin, asset turnover and financial leverage — so two companies with the same ROE can be told apart. This guide covers both the 3-step and 5-step versions. Educational only, with no buy, sell or hold advice.
Why ROE on its own can mislead
Two companies both report a 20% Return on Equity. One earns it on wide profit margins with very little debt. The other earns it on thin margins and a balance sheet funded largely by borrowing. The headline number is identical; the risk is not remotely comparable.
DuPont analysis is the method that separates them. Rather than treating ROE as one figure, it splits the number into the components that produced it, so you can see which lever is doing the work. That is the entire value of the technique — not the answer, which is just ROE, but the composition behind it.
The 3-step DuPont identity
The standard decomposition splits ROE into three multiplied terms.
| Component | Formula | What it measures |
|---|---|---|
| Net profit margin | Net Income ÷ Revenue | How much of each rupee of sales survives |
| Asset turnover | Revenue ÷ Total Assets | How hard the asset base works |
| Equity multiplier | Total Assets ÷ Equity | How much leverage sits underneath |
Multiply the three and revenue and total assets cancel out, leaving net income divided by equity — plain ROE. Worked example: revenue ₹14,500 crore, net profit ₹1,850 crore, total assets ₹12,000 crore, equity ₹6,200 crore. Margin is 12.76%, turnover 1.208x, multiplier 1.935x, giving an ROE of 29.84%.
The 5-step version and sector patterns
The 5-step form splits profit margin further into three parts: tax burden (net income divided by pre-tax profit), interest burden (pre-tax profit divided by EBIT) and operating margin (EBIT divided by revenue). Both versions arrive at exactly the same ROE.
The extra detail separates operating skill from financing and tax decisions. A falling operating margin masked by a one-off tax write-back is precisely the situation the 3-step view hides.
Sector shapes differ predictably. FMCG and pharmaceutical companies typically run high margins with low asset turnover. Retail and distribution run the reverse — thin margins on rapid turnover. Neither shape is better; they simply carry different risks.
Where DuPont breaks down
ROE flatters companies with a small equity base. A firm that has bought back heavily or carries accumulated losses can post a striking ROE on an otherwise weak business, purely because the denominator is small. If net worth is negative, ROE stops being mathematically meaningful altogether.
Use average equity and average assets across the year when the balance sheet has moved substantially. Year-end figures distort every ratio after a large fundraise or acquisition.
As with the other screening tools, this is not meaningful for banks and NBFCs — leverage is their business model, so the equity multiplier tells you nothing useful about risk. One-off items such as asset sales or exceptional provisions distort net margin badly, so normalise before comparing across years.

Frequently asked questions
What is DuPont analysis in simple terms?
It splits Return on Equity into the parts that create it: how much profit the company makes on each rupee of sales, how efficiently it uses its assets, and how much borrowed money sits underneath. Two companies with identical ROE can have completely different compositions.
What is a good equity multiplier?
There is no universal figure, as it depends heavily on the industry. As a general reference point, a multiplier above 3 means roughly two-thirds of the balance sheet is funded by liabilities rather than shareholders, which amplifies returns in good years and losses in bad ones.
Should I use the 3-step or 5-step version?
The 3-step version is enough to see whether ROE is driven by margin, efficiency or leverage. The 5-step version is worth the extra inputs when you want to separate operating performance from the effects of interest costs and tax, which the 3-step version combines into a single margin figure.
Does DuPont analysis work for banks?
Not usefully. Leverage is intrinsic to how banks and NBFCs operate, so a high equity multiplier reflects the business model rather than any risk signal. Financial companies are generally assessed with sector-specific measures instead.
