What Is Capital Expenditure (CapEx)? Formula, Meaning and Example
Understand Capital Expenditure or CapEx, its formula, types, effect on cash flow, and why investors compare CapEx with operating cash flow and free cash flow.
# What Is Capital Expenditure (CapEx)?
A company may generate cash from operations, but it often has to spend money to build factories, buy equipment, develop infrastructure or maintain existing assets.
These investments are known as Capital Expenditure, commonly abbreviated as CapEx.
CapEx matters because it directly affects how much cash remains after a company funds the assets required to operate and grow.
What Is Capital Expenditure?
Capital expenditure is spending on assets expected to provide benefits over more than one accounting period.
Examples include:
CapEx is different from ordinary operating expenses such as salaries, rent and electricity.
CapEx Formula
A common balance-sheet approximation is:
CapEx ≈ Ending Net PP&E − Beginning Net PP&E + Depreciation
However, this can be affected by asset disposals, acquisitions and accounting adjustments.
For practical analysis, investors often use the capital expenditure figure disclosed in the cash flow statement or annual report.
Example
Suppose:
Approximate CapEx:
₹2,500 − ₹2,000 + ₹300 = ₹800 crore
The actual reported figure may differ because of disposals and other adjustments.
Maintenance CapEx vs Growth CapEx
Maintenance CapEx
Maintenance CapEx is spending required to maintain existing operations.
For example, a manufacturing company may need to replace old machinery.
Growth CapEx
Growth CapEx is spending intended to increase future capacity or revenue.
For example, a company may build a new factory to serve a growing market.
Companies do not always disclose the two categories separately.
Why CapEx Matters to Investors
CapEx can tell you a lot about business economics.
A company with high CapEx may require significant reinvestment just to maintain operations.
Another company may have an asset-light model and require much less capital.
Consider two hypothetical businesses:
| Metric | Company A | Company B |
|---|---:|---:|
| CFO | ₹1,000 cr | ₹1,000 cr |
| CapEx | ₹800 cr | ₹200 cr |
| Approx. FCF | ₹200 cr | ₹800 cr |
Both generate the same operating cash flow, but Company B retains much more cash after capital expenditure.
That does not automatically make Company B the better investment. Growth prospects, competitive advantages and reinvestment opportunities still matter.
CapEx and Free Cash Flow
A common simplified formula is:
Free Cash Flow = CFO − CapEx
If CFO is ₹1,000 crore and CapEx is ₹600 crore:
FCF = ₹1,000 − ₹600 = ₹400 crore

High CapEx: Good or Bad?
High CapEx is not automatically negative.
Suppose a company spends ₹5,000 crore on a new production facility.
Initially, cash flow may fall sharply.
But if the facility eventually generates substantially higher revenue and cash flow, the investment could create value.
The key question is:
> What return is the company earning on the capital it is investing?
This connects CapEx with ROIC, ROCE and ROE.
CapEx Intensity
A simple measure is:
CapEx Intensity = CapEx ÷ Revenue × 100
Example:
CapEx intensity = 1,000 ÷ 10,000 × 100 = 10%
Compare companies within similar industries because capital requirements vary significantly.
CapEx and Depreciation
Depreciation is a non-cash accounting expense that spreads an asset's cost over its useful life.
CapEx is actual investment spending.
They are related but not identical.
If:
the company is spending substantially more on assets than the amount being depreciated during the period.
That may indicate expansion or heavy reinvestment, but the reason should be investigated.
CapEx and Debt
Large capital projects are sometimes funded partly through borrowing.
If a company has aggressive CapEx and insufficient operating cash flow, debt may increase.
Study CapEx alongside:
A large investment funded by debt is not necessarily dangerous, but future cash returns need to justify the financing burden.
Example: NIFTY Company Analysis
Imagine a hypothetical NIFTY company reports:
Approximate FCF:
₹2,000 − ₹1,200 = ₹800 crore

Frequently Asked Questions
Is CapEx an expense?
CapEx is an investment in long-lived assets. It is not normally expensed fully through the income statement immediately; depreciation generally recognizes the cost over time.
Where can I find CapEx?
Look at the company's cash flow statement, annual report and notes to the financial statements.
Is high CapEx bad for shareholders?
Not necessarily. High CapEx can support strong future growth if the company earns attractive returns on the investment.
Why is CapEx deducted from CFO?
CFO measures operating cash generation, while CapEx represents cash invested in long-term operating assets. The difference provides a simplified view of cash left after capital investment.
Final Thoughts
CapEx is one of the most important numbers for understanding how much capital a business needs to operate and grow.
The useful question is not simply, "How much is the company spending?"
Instead ask:
How much is it spending, why is it spending it, and what return is that capital likely to generate?
