Kotak Mahindra Bank vs Federal Bank (2026): NIM, ROA, Capital, Growth & Which Is Better?
2.14% ROA vs 1.22% ROA. 11.98% ROE vs 12.01% ROE.
Kotak Mahindra Bank versus Federal Bank contains one of the strangest return equations in Indian banking.
Kotak earns almost twice as much profit from each rupee of assets.
Yet shareholders' return on equity is almost exactly the same.
Kotak Q1 FY2027 ROA:
2.14%.
Federal Bank:
1.22%.
Kotak ROE:
11.98%.
Federal Bank:
12.01%.
The explanation is capital.
Kotak carries one of the largest common-equity cushions in Indian banking.
Federal Bank runs with materially more balance-sheet leverage.
That makes this comparison less about which bank has the better headline return and more about how efficiently each uses capital to produce shareholder earnings.
The ₹100-equity paradox
Kotak's huge 22.4% CET1 ratio means every ₹100 of equity supports a relatively conservative quantity of risk-weighted assets.
Federal Bank's capital base is healthy but much smaller relative to its lending balance sheet, allowing 1.22% ROA to translate into roughly the same ROE as Kotak.
This is neither automatically good nor bad.
More equity gives Kotak greater resilience and growth capacity.
More leverage allows Federal Bank to convert a lower asset return into competitive shareholder returns.
The question is which balance provides the better combination of growth, downside protection and valuation.

Kotak begins with a 120-basis-point NIM advantage
Kotak Mahindra Bank:
4.53%.
Federal Bank:
3.33%.
A 120-basis-point margin difference is enormous.
It means Kotak produces materially more net interest income for a similar quantity of earning assets before operating costs and credit losses enter the picture.
Kotak's funding franchise is one reason
CASA ratio:
40.3% versus Federal Bank at 32.23%.
Kotak's cost of funds was approximately 4.46%.
Federal Bank's cost of deposits was 5.21%.
The measures are not perfectly definition-matched, but the broad conclusion is clear:
Kotak operates with a materially cheaper liability structure.
That funding advantage creates room for conservatism
Kotak does not need to chase the highest-yielding loans simply to produce acceptable margins.
This allows management to choose between:
- pricing.
- risk quality.
- customer acquisition.
- growth.
with more flexibility than a bank beginning with a thinner spread.
Federal Bank is nevertheless closing the margin gap
A year earlier, Federal Bank NIM was approximately 2.94%.
It reached 3.33% in Q1 FY2027.
That 39-basis-point increase is one of the strongest improvements among comparable Indian private banks.
The absolute margin remains lower than Kotak's.
The direction is much stronger.
Federal Bank's growth engine is the main reason the stock deserves comparison with Kotak
NII grew:
26.06%.
PAT grew:
36.57%.
Fee income increased:
21.71%.
CASA balances increased:
18.26%.
Kotak's current growth is healthy.
Federal Bank's current earnings acceleration is substantially faster.
Kotak's own Q1 was not weak
Standalone PAT increased 26%.
NII increased 9%.
Customer assets increased 16%.
Operating profit increased approximately 10%.
Gross NPA fell sharply year on year.
ROA rose to 2.14%.
It is a strong quarter.
Federal simply has much greater operating momentum from a smaller base.
This is the first major valuation question
How much faster can Federal Bank grow than Kotak before the difference in current profitability disappears?
If Federal continues growing NII above 20% while Kotak remains near high single digits, the gap in absolute scale will narrow over time.
But convergence from ₹3.2 lakh crore of deposits toward Kotak's ₹5.7 lakh crore is still a multi-year process.
Kotak has the much better ROA
2.14% versus 1.22%.
This is the most important current quality difference.
Kotak earns approximately 75% more profit per rupee of assets on a relative basis.
That is difficult for Federal Bank to offset merely through higher percentage growth.
Then ROE produces the paradox
Kotak:
11.98%.
Federal:
12.01%.
Federal earns roughly the same shareholder return despite much lower asset profitability.
The reason is leverage.
Kotak is carrying an enormous amount of excess equity
CET1:
22.4%.
Total capital:
22.8%.
Federal Bank total capital is around 17%.
Kotak therefore funds much more of its balance sheet with shareholder equity rather than liabilities.
That reduces financial risk.
It also mechanically reduces ROE.
This is why Kotak's 12% ROE should not be interpreted as poor banking economics
A 2.14% ROA bank with 22% CET1 is very different from a 1.2% ROA bank producing 12% ROE through higher leverage.
Kotak has the option to deploy more capital over time.
If it can increase assets faster without sacrificing credit quality, ROE can rise even if ROA remains unchanged.
Federal has less unused capital optionality
Federal Bank is adequately capitalised.
But its balance sheet is already using equity more intensively.
Its future ROE improvement therefore depends more heavily on:
- higher ROA.
- lower cost-to-income.
- better NIM.
- fee growth.
rather than merely deploying surplus capital.
Operating efficiency gives Kotak another major advantage
Cost-to-income:
Kotak 45.6%.
Federal Bank 52.50%.
A seven-percentage-point gap is meaningful.
Kotak preserves more of every rupee of operating income before provisions.
Federal's efficiency is improving
Its cost-to-income ratio improved by roughly 239 basis points year on year.
This is exactly the operating leverage investors need to see.
If Federal can move sustainably below 50%, the ROA gap can narrow without requiring a dramatic increase in risk appetite.
Federal's path to 1.4%-plus ROA is visible
A plausible combination would be:
- NIM stays around 3.3%-3.4%.
- Cost-to-income falls below 50%.
- Credit cost remains around 0.4%-0.5%.
- Fee income continues double-digit growth.
- Advances continue mid-teens growth.
That would materially improve profit density.
Kotak's route to higher ROE is different
Kotak already has high ROA.
It needs to deploy its balance sheet and capital more aggressively while keeping:
- GNPA near current levels.
- NIM above 4.4%.
- Credit cost below 0.6%.
- CASA around 40%.
Its opportunity is capital productivity rather than business repair.
Asset quality gives each bank a different victory
Gross NPA:
Kotak 1.18%.
Federal Bank 1.52%.
Kotak carries less recognised gross stress.
Net NPA:
Kotak 0.27%.
Federal Bank 0.18%.
Federal has less residual unprovided stress.
Federal's provisioning is deeper
Provision coverage excluding technical write-offs was approximately 87.37%.
Kotak's PCR was around 78%.
This explains why Federal's net NPA is lower despite having the higher gross NPA.
Kotak's slippage trend improved sharply
Fresh slippages declined approximately 27% year on year.
Credit cost fell to 0.46% from 0.93% a year earlier.
GNPA fell to 1.18% from 1.48%.
This is a powerful combination:
higher profitability while credit stress is moving lower.
Federal's fresh slippages also improved
Fresh slippages fell almost 38% year on year.
The slippage ratio improved to approximately 0.61%.
Credit cost was around 0.41%.
Neither bank currently has a problematic credit-cost profile.
The current credit-cost difference is economically minor
Kotak:
0.46%.
Federal:
0.41%.
A five-basis-point difference is not enough to explain the 92-basis-point ROA gap.
That gap comes mainly from operating architecture:
- margin.
- cost efficiency.
- asset mix.
- capital structure.
Kotak has a future scale catalyst: Deutsche Bank India's retail business
Kotak has signed an agreement to acquire Deutsche Bank India's retail banking business.
The transaction is expected to add approximately:
- ₹29,000 crore of loans.
- ₹16,000 crore of deposits.
- ₹10,500 crore of assets under management.
- around 150,000 customers.
The expected closing is in 2027 and remains subject to regulatory approvals and transaction conditions.
None of those balances should be included in Kotak's current Q1 FY2027 operating metrics.
The acquisition is strategically more interesting than its size
Relative to Kotak's ₹5.7 lakh crore deposit franchise, the acquired balances are not transformative by themselves.
The opportunity lies in acquiring:
- affluent customers.
- wealth relationships.
- salary and retail accounts.
- cross-sell opportunities.
at a bank already strong in affluent financial services.
Federal Bank's catalyst is entirely organic
Federal does not need a large acquisition to change its economics.
Its current operating strategy already provides the levers:
- higher-yield chosen segments.
- NR franchise growth.
- stronger CASA.
- lower cost of deposits.
- cost efficiency.
This makes Federal's transformation easier to measure quarter by quarter.
Valuation is much closer than the ROA gap suggests
August 28, 2026:
- Kotak P/E: 20.77x.
- Kotak P/B: 2.26x.
- Federal Bank P/E: 18.15x.
- Federal Bank P/B: 2.14x.
Federal is cheaper on both measures.
The P/B difference is surprisingly small.
Kotak costs only about 6% more on book value
2.26x versus 2.14x.
Yet Kotak's ROA is roughly 75% higher.
That makes Kotak's book-value premium look modest if current ROA is sustainable.
But Federal's faster growth deserves some premium consideration
The valuation cannot be judged on current ROA alone.
Federal's:
- 26% NII growth.
- 37% PAT growth.
- 39-basis-point NIM expansion.
- 18% CASA-balance growth.
create a plausible path to much higher future profitability.
This means the valuation debate is duration versus acceleration
Kotak: pay slightly more for profitability already present.
Federal: pay slightly less for profitability that is improving faster.
The answer depends on how long Federal can compound above Kotak's growth rate.
Federal Bank's strongest rerating milestone is not another 35% PAT-growth quarter
It is ROA moving sustainably above 1.3%-1.4%.
That would demonstrate that the growth is becoming structurally more valuable.
A higher ROA would also support a better ROE without requiring greater leverage.
Kotak's strongest rerating milestone is higher ROE without sacrificing ROA
The bank already earns 2.14% ROA.
The market wants evidence that its massive capital cushion can be deployed more productively.
ROE moving toward the mid-teens while ROA remains above 2% would substantially strengthen the compounding argument.
The stock-split issue makes Kotak's raw long-term Bull Run chart misleading
Kotak Mahindra Bank subdivided each ₹5 equity share into five ₹1 shares effective January 14, 2026.
Raw unadjusted price fields can therefore incorrectly show an enormous one-year decline or an impossible 52-week high comparison.
This article deliberately does not use Kotak's raw Bull Run one-year return or unadjusted 52-week range.
Post-split Bull Run momentum is usable

Federal Bank has already received substantial medium-term market recognition
The stock gained more than 20% over three months and nearly 16% over six months in Bull Run's August 25 snapshot.
Kotak was much flatter over three months and negative over six months.
This matters because Federal's faster growth is no longer an undiscovered story.
The most important Kotak metric from here
ROE.
NIM is already high.
ROA is already high.
Asset quality is already strong.
The bank needs to prove that extraordinary common-equity capital can be deployed into enough profitable assets to raise shareholder returns.
The most important Federal Bank metric
ROA.
Federal already has earnings growth.
It already has improving NIM.
It already has low net NPA.
Higher ROA is the missing confirmation that the new growth mix is creating structurally better economics.
What can break each thesis?
Kotak Mahindra Bank
- ROE remains near 12% despite very high capital.
- NIM compresses materially below 4.5%.
- Credit-deposit ratio rises without stronger deposit growth.
- The Deutsche Bank India acquisition takes longer or generates weaker synergies than expected.
- High capital becomes permanently under-utilised.
Federal Bank
- NIM expansion reverses.
- Cost-to-income remains above 50%.
- Higher-yield lending segments produce future slippage.
- ROA remains around 1.2% despite strong earnings growth.
- Recent stock rerating gets ahead of actual profitability improvement.
