Capital Efficiency: Why Growth Can Still Destroy Value

What the next ₹10 of profit can reveal about the quality of a business.

Picture two companies presenting their annual results.

Both announce the same thing: profit increased by ₹10.

It sounds equally impressive.

Then someone asks a different question.

How much money did each company invest to earn that additional profit?

The first invested ₹50. The second invested ₹100.

Suddenly, the story looks very different.

 The ₹50 Difference 

On paper, both companies produced the same additional profit.

But the first company still has ₹50 left. It can use that money to expand again, repay debt or prepare for a difficult year.

The second company has already used it.

That is capital efficiency in simple terms. It tells us how much profit and cash a business can produce from the money invested in it.

TCS and DMart: Two Different Routes

TCS and DMart show that capital efficiency does not look the same in every business.

TCS reported a 51.4% return on equity, while cash flow from operations was equal to 105.9% of its net profit in FY2025-26.

Its business relies heavily on people, knowledge, and execution. It does not require the same level of factories or inventory as a manufacturing or retail company.

DMart works differently.

It reported a 7.54% operating margin and inventory turnover of 10.68 times. Its margin on each sale is relatively smaller, but products move quickly through its stores.

These numbers should not be compared directly. The business models are different.

TCS depends on talent and cash generation. DMart depends on store economics and how efficiently it moves inventory.

 What Investors Should Ask 

The next time a company announces record growth, the headline should only be the beginning.

How much fresh capital did that growth require?

What return did the company generate from that capital?

Did the reported profit actually turn into cash?

Revenue growth tells us that a company became bigger.

Capital efficiency tells us whether getting bigger was worth the money.

Before celebrating growth, ask what that growth cost.
