Every business spends money in two fundamental ways — on long-term assets that last for years, and on day-to-day costs to keep the business running. In finance, these are called CAPEX and OPEX. Understanding the difference between them is essential for reading financial statements and evaluating companies as an investor.
CAPEX vs OPEX — Full Forms
| CAPEX | OPEX | |
|---|---|---|
| Full Form | Capital Expenditure | Operating Expenditure |
| What It Is | Spending on long-term assets | Spending on day-to-day operations |
| Duration of Benefit | Multiple years | Current period only |
What is CAPEX?
CAPEX (Capital Expenditure) is money spent to acquire, build, or upgrade long-term assets that will generate value for more than one financial year. These assets — called fixed assets or PP&E (Property, Plant & Equipment) — include factories, machinery, land, buildings, vehicles, and technology infrastructure.
Because CAPEX assets provide value over many years, they are not expensed immediately. Instead, they are recorded on the balance sheet and gradually depreciated over their useful life.

What is OPEX?
OPEX (Operating Expenditure) is money spent on the day-to-day costs of running the business — costs that are consumed within the current financial period and do not create long-term assets.
OPEX is expensed immediately on the income statement, reducing profit in the period it is incurred.
CAPEX vs OPEX — Real World Examples
| Scenario | CAPEX or OPEX? | Why |
|---|---|---|
| Buying a new factory building | CAPEX | Long-term asset, useful life 30+ years |
| Monthly factory rent | OPEX | Recurring cost, no asset created |
| Purchasing new machinery | CAPEX | Long-term productive asset |
| Machine repair and maintenance | OPEX | Restores existing asset, not an upgrade |
| Building a new data centre | CAPEX | Long-term infrastructure asset |
| Monthly cloud hosting fees | OPEX | Recurring service cost, no owned asset |
| Employee salaries | OPEX | Period cost, consumed immediately |
| Buying a company vehicle fleet | CAPEX | Long-term asset, depreciated over years |
| Annual software subscription (SaaS) | OPEX | Service fee, no asset ownership |
| Custom software development (owned) | CAPEX | Intangible asset, amortised over years |
CAPEX vs OPEX — Accounting Treatment
| Feature | CAPEX | OPEX |
|---|---|---|
| Where It Appears | Balance Sheet (as fixed asset) | Income Statement (as expense) |
| Immediate Profit Impact | None — only via annual depreciation | Full amount reduces profit immediately |
| Cash Flow Statement | Cash Flow from Investing Activities | Cash Flow from Operating Activities |
| Tax Treatment | Depreciation is tax-deductible annually | Full amount tax-deductible in the same year |
| Long-term Asset Created? | Yes | No |
How CAPEX and OPEX Affect EBITDA and PAT
This is where the accounting distinction becomes critical for investors:
- OPEX reduces EBITDA directly — since it is expensed immediately on the income statement
- CAPEX does NOT reduce EBITDA — only the annual depreciation charge reduces EBIT (and therefore PAT)
Example: A company spends ₹100 crore on a new factory (CAPEX) with a 20-year life:
| Year | CAPEX Cash Outflow | Depreciation Hit to Profit | EBITDA Impact |
|---|---|---|---|
| Year 1 | ₹100 crore | ₹5 crore | Zero |
| Year 2 | Zero | ₹5 crore | Zero |
| Years 3–20 | Zero | ₹5 crore/year | Zero |
This is why EBITDA is a popular metric for capital-intensive businesses — it strips out the depreciation effect of past CAPEX and shows the true cash-generating ability of the business.
The Cloud Shift — CAPEX to OPEX in Tech
One of the most significant business model shifts of the last decade has been the movement from CAPEX to OPEX in technology:
- Old model (CAPEX): Companies bought and maintained their own servers, data centres, and IT infrastructure — large upfront capital costs
- New model (OPEX): Companies use AWS, Google Cloud, Azure — paying monthly subscription fees instead of owning infrastructure
This shift has dramatically reduced the CAPEX requirements for tech companies, improved their ROCE, and increased operating flexibility. It also benefits cloud providers like AWS who receive large, predictable OPEX revenue streams.
CAPEX vs OPEX — Investor Perspective
When high CAPEX is a positive signal:
- Company is investing in growth — new capacity, new geographies, new products
- CAPEX is generating returns above cost of capital (rising ROCE over time)
- Company has strong cash flows to fund CAPEX without excessive debt
When high CAPEX is a concern:
- CAPEX consistently exceeds operating cash flows — company needs debt or equity to fund it
- Maintenance CAPEX is high relative to revenue — old assets being replaced without growth
- CAPEX has not translated into revenue or profit growth over 3–5 years
When high OPEX is a concern:
- OPEX growing faster than revenue — operating leverage is negative
- High employee costs that are difficult to reduce in downturns
- Rising raw material costs squeezing EBITDA margins
Key Takeaways
- CAPEX = Capital Expenditure — spending on long-term assets, capitalised on balance sheet
- OPEX = Operating Expenditure — day-to-day costs, expensed immediately on income statement
- CAPEX reduces profit gradually via depreciation; OPEX reduces profit immediately
- CAPEX appears in Cash Flow from Investing; OPEX in Cash Flow from Operations
- High growth CAPEX is positive if it generates returns above cost of capital
- The shift from CAPEX to OPEX (cloud computing) has transformed tech company economics
Frequently Asked Questions (FAQ)
Q: What is the difference between CAPEX and OPEX?
CAPEX (Capital Expenditure) is spending on long-term assets like machinery, buildings, or infrastructure that provide value over multiple years. OPEX (Operating Expenditure) is spending on day-to-day business costs like salaries, rent, and utilities that are consumed in the current period. CAPEX is capitalised on the balance sheet; OPEX is expensed immediately on the income statement.
Q: Is rent CAPEX or OPEX?
Monthly rent is OPEX — it is a recurring operating cost consumed in the current period with no long-term asset created. However, if a company purchases a property outright, that purchase is CAPEX. Note: under Ind AS 116 (lease accounting), long-term lease commitments are now capitalised on the balance sheet as right-of-use assets, blurring the traditional CAPEX/OPEX distinction for leases.
Q: Is salary CAPEX or OPEX?
Employee salaries are OPEX — they are period costs consumed immediately and appear on the income statement. The only exception is when employee costs are directly attributable to building a capital asset (e.g., engineers’ salaries during construction of a plant) — in that case, the labour cost can be capitalised as part of the asset’s cost.
Q: Why do companies prefer OPEX over CAPEX?
Many companies prefer OPEX because it requires no large upfront investment, offers flexibility to scale up or down, and has immediate tax deductibility. This is why cloud computing (paying for AWS/Azure monthly) has become popular vs owning data centres. OPEX also keeps the balance sheet lighter, improving ROCE metrics.
Q: Does CAPEX affect EBITDA?
No. CAPEX itself does not affect EBITDA because it is not expensed on the income statement — it is capitalised. However, the annual depreciation that follows CAPEX reduces EBIT (Earnings Before Interest and Tax). EBITDA adds back depreciation, which is why it strips out the impact of past CAPEX decisions.
Q: How do I find CAPEX and OPEX in a company’s annual report?
CAPEX is found in the Cash Flow Statement under “Cash Flow from Investing Activities” — look for “Purchase of PP&E” or “Purchase of Fixed Assets.” OPEX components are found on the Income Statement — employee costs, raw materials, rent, and other operating expenses are all OPEX items.
