Capex is the cash a business spends on long-term physical assets: buildings, machinery, vehicles, IT infrastructure. Calculate it as current PP&E minus previous PP&E plus depreciation (which reduced the book value). Capex intensity - capex as percentage of revenue - tells you whether the business is asset-light (under 3%) or asset-heavy (15%+).

Current PP&E 8M, previous 6M, depreciation 1.5M = capex of 3.5M. On 30M revenue, that's 11.7% capex intensity - typical of industrial manufacturing. Software and consulting businesses usually show 1-3% intensity (servers, laptops); utilities and telecom 15-25% (infrastructure-heavy).

Maintenance capex (just keeping the existing business running) is often 60-80% of total capex. Growth capex (expanding capacity) is the balance. Separating the two is critical: 5M maintenance capex on a 50M revenue business isn't growth investment - it's the cost of running the existing machinery. Investors reward growth capex much more than maintenance.

Run it with sensible defaults

Using current pp&e of 8,000,000, previous pp&e of 6,000,000, depreciation of 1,500,000, revenue of 30,000,000, the calculation works out to 3,500,000.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Current PP&E (end), Previous PP&E (start), Depreciation (period), and Revenue (for intensity) — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Capex = current PP&E - previous PP&E + depreciation. Intensity = capex ÷ revenue × 100. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

What to do with a low result

A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

£8,000,000 £ current PP&E - £6,000,000 £ prior + £1,500,000 £ depreciation = $3,500,000.00.

Inputs

Current PP&E (end):8,000,000 £
Previous PP&E (start):6,000,000 £
Depreciation (period):1,500,000 £
Revenue (for intensity):30,000,000 £
Expected Result$3,500,000.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Capex = current PP&E - previous PP&E + depreciation. Intensity = capex ÷ revenue × 100.

Frequently Asked Questions

Why add back depreciation?
Depreciation reduced the book value of PP&E without any cash movement. If PP&E went up 2M net of 1.5M depreciation, the actual spend was 3.5M - the capex bought 3.5M of new assets, offset by 1.5M of existing assets depreciating down.
Maintenance vs growth capex?
Maintenance capex replaces worn assets to keep current operations running. Growth capex adds new capacity. Roughly: maintenance ≈ depreciation, growth = total capex - depreciation. This split matters for free cash flow valuation.
What's a good capex intensity?
Industry-dependent: Software 1-3%. Retail 2-5%. Manufacturing 5-10%. Telecom/utilities 15-25%. Mining/oil 20-30%. High intensity isn't bad if it supports growth; bad if it just replaces ageing assets without adding capacity.
Does this include acquisitions?
No. Acquisitions are typically reported separately as 'acquisition-related capex' or M&A investing cash outflow. This calculator measures organic capex only. Pure PP&E purchases show up as the difference here.
