What is Capital Expenditure (CapEx)?

Capital Expenditure (CapEx) is money spent to acquire, upgrade, or maintain physical assets - property, buildings, machinery, equipment, and technology infrastructure - that will be used for more than one year. Unlike operating expenses, which flow through the income statement immediately, CapEx is capitalised on the balance sheet and expensed gradually as depreciation over the asset's useful life.

CapEx is categorised as maintenance CapEx (spending to keep existing assets operational) or growth CapEx (spending to expand capacity or enter new markets). Growth CapEx is an investment in future revenue; maintenance CapEx is essentially a cash cost of running the current business.

Because EBITDA excludes depreciation, it effectively excludes CapEx as well - making EBITDA a poor proxy for free cash flow in capital-intensive businesses. A telecom company or manufacturer with high EBITDA but equally high maintenance CapEx may generate very little actual free cash.

When to use Capital Expenditure (CapEx)

Use CapEx analysis when assessing whether a business's EBITDA is truly convertible to cash (low CapEx = high conversion; high CapEx = lower conversion). Maintenance CapEx should be roughly equal to annual D&A in a mature business. If CapEx consistently exceeds D&A, the business is growing its asset base.

Worked examples for Capital Expenditure (CapEx)

This table quickly gives you the overview you need to understand Capital Expenditure (CapEx) and its most important comparisons.

Common pitfalls

CapEx can be deferred in the short term, making free cash flow appear temporarily strong. A business that delays maintenance CapEx will eventually need to spend more to repair degraded assets. Always review multi-year CapEx trends rather than a single year's figure.

Frequently asked questions about Capital Expenditure (CapEx)

What is the difference between CapEx and OpEx?

CapEx is spending on long-lived assets (>1 year useful life) that appears on the balance sheet and is expensed via depreciation. OpEx is spending on day-to-day operations that flows through the income statement immediately. The distinction affects reported profit: CapEx has no immediate income statement impact; OpEx reduces profit in the period incurred.

Is software CapEx or OpEx?

It depends. Purchased software licences are typically CapEx. Cloud/SaaS subscriptions are typically OpEx. Internally developed software can be either, depending on the development stage and accounting policy (US GAAP ASC 350-40 governs this).

How does CapEx relate to Free Cash Flow?

Free Cash Flow = Operating Cash Flow − CapEx. CapEx is the primary deduction from operating cash flow to arrive at FCF. A business that generates strong operating cash flow but has heavy CapEx requirements will have thin FCF despite healthy earnings.

1. How does CapEx differ from operating expenses (OpEx) on the financial statements?

A CapEx covers only technology investments; OpEx covers all other business costs B CapEx reduces EBITDA directly, while OpEx reduces only net income C CapEx is capitalised on the balance sheet and expensed as depreciation over the asset's life, while OpEx flows through the income statement immediately D CapEx requires government disclosure; OpEx does not require formal reporting

ℹ Unlike OpEx which hits the income statement immediately, CapEx is capitalised on the balance sheet and expensed gradually as depreciation over the asset's useful life. This is why CapEx does not directly reduce EBITDA but still represents real cash outflow.

2. From the examples table, which company type achieves the highest FCF conversion on $5,000,000 EBITDA?

A SaaS company - 96% conversion with $200,000 CapEx B Manufacturer - 60% conversion with $2,000,000 CapEx C Telecom operator - 30% conversion with $3,500,000 CapEx D Retailer - 45% conversion with $2,750,000 CapEx

ℹ The SaaS company converts 96% of EBITDA to FCF because it requires only $200,000 in CapEx, generating $4,800,000 in free cash flow. The telecom operator, with $3,500,000 in CapEx, converts only 30% - illustrating why CapEx intensity is critical to evaluating EBITDA quality.

3. What does the whenToUse section say maintenance CapEx should roughly equal in a mature business?

A Annual revenue multiplied by the industry CapEx intensity ratio B Annual operating profit after adjusting for working capital changes C Annual EBITDA divided by a standard industry valuation multiple D Annual D&A (depreciation and amortization)

ℹ The whenToUse section states that maintenance CapEx should be roughly equal to annual D&A in a mature business. If CapEx consistently exceeds D&A, the business is growing its asset base. The relationship between CapEx and D&A is a key indicator of whether a business is investing for growth or just maintaining existing capacity.

4. What does the pitfalls section warn about deferring maintenance CapEx in the short term?

A Deferred CapEx triggers an immediate EBITDA restatement under GAAP B It makes FCF appear temporarily strong, but eventually leads to higher spending when degraded assets need repair C Deferred CapEx must be disclosed as a contingent liability on the balance sheet D Deferred CapEx reduces depreciation charges, which overstates EBIT in subsequent periods

ℹ The pitfalls section warns that deferring CapEx makes free cash flow appear temporarily strong. Eventually the business must spend more to repair or replace degraded assets. This is why multi-year CapEx trends must be reviewed rather than a single year's figure.

5. According to the FAQ, what standard governs whether internally developed software is treated as CapEx or OpEx?

A US GAAP ASC 350-40, which classifies software based on development stage and accounting policy B IFRS 16, which requires all internally developed software to be expensed immediately as OpEx C GAAP ASC 606, based on revenue recognition timing for the software product D There are no formal standards - the classification is left entirely to company discretion

ℹ The FAQ states that internally developed software can be either CapEx or OpEx depending on the development stage and accounting policy, with US GAAP ASC 350-40 governing this. Purchased software licences are typically CapEx; cloud and SaaS subscriptions are typically OpEx.
