# What Is CapEx to Sales Ratio?

The CapEx to Sales ratio compares capital expenditure with revenue.

CapEx to Sales = Capital Expenditure ÷ Revenue × 100

It helps investors understand how much of a company's sales are being reinvested into long-term assets.

Example

Suppose:

Revenue = ₹10,000 crore
CapEx = ₹1,500 crore

CapEx to Sales = 15%

Why Does CapEx Intensity Matter?

Different businesses require different levels of investment.

A software business may have relatively low physical CapEx, while manufacturing, infrastructure and telecom businesses can require substantial investment.

Therefore, CapEx to Sales helps investors understand capital intensity.

Comparing Two Hypothetical Companies

| Metric | Company A | Company B |

|---|---:|---:|

| Revenue | ₹10,000 cr | ₹10,000 cr |

| CapEx | ₹800 cr | ₹2,500 cr |

| CapEx/Sales | 8% | 25% |

Company B commits a much larger share of revenue to capital expenditure.

That is not automatically negative. It may be investing for future growth.

Growth CapEx vs Maintenance CapEx

Maintenance CapEx keeps existing operations functioning.

Growth CapEx expands capacity or supports future growth.

Financial statements may not always provide a clean split, so investors may need management commentary and company disclosures.

Relationship With Free Cash Flow

A simplified formula is:

FCF = Operating Cash Flow − CapEx

Example:

CFO = ₹2,000 crore
CapEx = ₹800 crore
FCF = ₹1,200 crore

If CapEx rises to ₹1,400 crore while CFO remains unchanged:

CFO = ₹2,000 crore
CapEx = ₹1,400 crore
FCF = ₹600 crore

The business may still be investing productively, but near-term free cash flow is lower.

What Investors Should Examine

Look at CapEx to Sales together with:

Revenue growth
Operating cash flow
Free cash flow
Return on capital
Capacity utilisation
Debt
Depreciation
Expansion plans

High CapEx with strong expected returns can mean something very different from high CapEx with weak returns.

NIFTY-Style Example

Imagine a hypothetical NIFTY manufacturer with:

Revenue = ₹20,000 crore

CapEx = ₹3,000 crore

CapEx/Sales = 15%

The investor should examine what the new capacity is expected to produce and whether returns justify the investment.

Frequently Asked Questions

Is a lower CapEx to Sales ratio better?

Not necessarily. Low CapEx can mean an asset-light business, but it can also mean underinvestment.

Does CapEx reduce profit immediately?

Generally, capital expenditure is capitalised as an asset and expensed over time through depreciation rather than entirely immediately.

Is CapEx to Sales the same as CapEx intensity?

It is one simple measure of capital intensity. Other measures can also be used.

Final Thoughts

CapEx to Sales answers a useful question:

How much of the company's revenue is being committed to long-term investment?

Use it with cash flow and return-on-capital measures to understand whether that investment is creating economic value.
