CAPEX vs OPEX: budgeting an industrial project
The purchase price is only the start — budget the full capital scope and the operating costs it locks in.
Short answer
What belongs in the CAPEX budget?
Capital expenditure covers everything needed to deliver a working asset, not just the machine price.
- Core equipment and auxiliary systems
- Freight, insurance, duties and inland delivery
- Installation, utilities connection and commissioning
- FAT/SAT, training, documentation and initial spares
- Civil works, electrical and infrastructure upgrades
- Contingency — typically 10–15% for industrial projects
What belongs in the OPEX budget?
Operating expenditure starts the day the line runs and continues for its whole life.
- Energy, water, steam and compressed air
- Operators, maintenance staff and supervision
- Wear parts, consumables and planned maintenance
- Service contracts and emergency call-outs
- Insurance, compliance and recertification
How does the split change supplier choice?
Two quotations with the same purchase price can have very different lifetime costs. A machine with higher energy efficiency, better local service and cheaper spares can repay a higher CAPEX within a few years. This is why total cost of ownership — not headline price — should drive the comparison.
How does the split affect financing?
Lenders and investors look at both sides: CAPEX defines the funding amount, while OPEX defines whether the project can service debt. A bankable project document shows the full capital scope, realistic operating costs and the revenue assumptions that connect them.
Quick questions
Is installation CAPEX or OPEX?+
Installation, commissioning and testing are capitalized as part of the asset cost — they are CAPEX.
How much contingency should an industrial project carry?+
Commonly 10–15% of the capital budget, higher for first-of-kind processes or uncertain site conditions.
Can OPEX be financed?+
Working capital facilities exist for operating costs, but they are separate from project CAPEX financing and are assessed differently by lenders.
Summary
- CAPEX buys the asset; OPEX runs it — budget both before choosing a supplier
- Compare offers on total cost of ownership, not purchase price
- Financing decisions depend on a credible view of both sides
