What Is CapEx? Capital Expenditure Explained + Formula

Someone on your finance team just used the word "CapEx" in a meeting, and you nodded as if you knew. If you are reading this, you are likely trying to clean up your balance sheet, prepare for a growth phase, or figure out why your free cash flow does not match your net profit.

You do not need a lecture on "investing in your future." You need to know exactly what is CapEx, how to compute it without errors, and why mismanaging it destroys your company's value. Let's fix that in five minutes — just the math and what it means for your next budget call.

What Is CapEx And Its Categories?

CapEx stands for Capital Expenditure. It's money a company spends to buy, upgrade, or maintain a long-term asset — something that keeps delivering value for more than one year. Think: office buildings, servers, delivery trucks, machinery, or sales planning software you build for internal use over multiple years.

That's the whole definition. Anyone who makes it longer than that is padding.

You cannot treat all capital spending the same way. It divides into two categories:

- Maintenance CapEx: The money you spend just to keep the lights on and stop your current assets from breaking down. Think of replacing a broken factory conveyor belt or fixing a roof. You are not growing; you are defending. - Growth CapEx: The money you spend to acquire new capacity. This means buying a second factory, purchasing a competitor, or expanding your footprint into a new region to capture market share.

What Is Capital Expenditure Actually, in Practice?

If you're asking "what are capital expenditures" because you're staring at an invoice and don't know where to file it, ask one question: will this asset still be useful to the business in 12+ months?

- Yes → CapEx. A new warehouse, a fleet of vans, a manufacturing line, a multi-year software build. - No → OpEx. This month's cloud hosting bill, a one-time consultant fee, office snacks.

Simple test. Use it every time. Accountants overcomplicate this to sound smart. You don't need to.

How To Calculate CapEx Precisely

Here's where most articles get lazy and skip the numbers. Not here.

CapEx = Change in Net PP&E + Depreciation Expense

Where:

- Net PP&E = Property, Plant & Equipment (net of depreciation), taken from the balance sheet - Depreciation Expense = the depreciation charge for the period, taken from the income statement or cash flow statement

Worked Example

Say your company's balance sheet shows:

- Net PP&E this year: €500,000 - Net PP&E last year: €420,000 - Depreciation expense this year: €60,000

Run the calculation:

- CapEx = (€500,000 − €420,000) + €60,000 - CapEx = €80,000 + €60,000 - CapEx = €140,000

That's it. Your company spent €140,000 on long-term assets this year. No guesswork, no adjectives, just arithmetic anyone can check.

If you don't have the balance sheet handy, you can also pull the number straight off the cash flow statement; it's usually listed as "Purchases of Property and Equipment" or "Capital Expenditures" under Investing Activities. That figure is your CapEx, already calculated for you.

Two Ways to Handle CapEx Numbers

Do not let your finance team overcomplicate this. There are only two ways to run a CapEx calculation: the Direct Method (if you have clean internal ledgers) and the Indirect Method (if you are analysing a competitor or a vendor using only their public financial statements).

1. The Direct Method

If your books are clean and you use modern tracking tools, you simply sum your asset invoices and subtract any cash you brought in by selling old gear.

Net CapEx = Cost of New Assets − Cash Received from Selling Old Assets

2. The Indirect Method

If you only have access to a standard Balance Sheet and Income Statement, you have to infer the number. You look at the net change in Property, Plant, and Equipment (PP&E) and add back the non-cash depreciation that lowered that asset value during the year.

CapEx = Ending PP&E − Beginning PP&E + Current Depreciation Expense

A Worked Example

Imagine your company started the fiscal year with a net PP&E value of €500,000 on the balance sheet.

By the end of the year, your balance sheet shows your net PP&E is €700,000.

Your income statement for that same year shows a depreciation expense of €100,000.

Let's plug those numbers into the formula:

- CapEx = (€700,000 − €500,000) + €100,000 - CapEx = €200,000 + €100,000 = €300,000

Your capital expenditure for the year was €300,000.

Why do we add depreciation back? Because depreciation is a non-cash accounting entry that artificially lowered your ending PP&E value. If you did not add it back, you would underestimate your actual cash investment by €100,000. That is a dangerous mistake when calculating your true free cash flow.

Bottom Line

So, what is CapEx actually? CapEx is money spent on assets that last. Calculate it with change in Net PP&E plus depreciation. Use it to justify big spend only when the revenue plan behind it is just as rigorous as the accounting. If your CapEx approvals are backed by spreadsheets that go stale the moment a rep changes territory, you don't have a planning problem; you have a math problem.
