CAPEX vs OPEX

Also known as: CAPEX, OPEX, Capital vs Operating Expenditure

Accounting distinction between capital expenditure (long-term assets) and operational expenditure (day-to-day recurring costs).

Updated: 2026-01-04

Definition

CAPEX (Capital Expenditure) and OPEX (Operating Expenditure) are the two fundamental categories of business spending, with profoundly different accounting, tax, and strategic implications.

CAPEX (capital expenditures) are investments in long-term assets that generate value beyond the current fiscal year. They include purchase of property, machinery, technology, buildings. Accounting-wise, CAPEX are capitalized on the balance sheet as assets and depreciated/amortized over time. Example: Server purchase for 100,000 euros depreciated over 5 years (20,000 euros/year to income statement).

OPEX (operating expenditures) are recurring costs to maintain day-to-day business operations. They include salaries, rent, utilities, maintenance, software subscriptions. OPEX immediately impact the income statement in the year incurred. Example: 20,000 euros/year SaaS subscription fully recorded as cost in the year.

The distinction is crucial because:

  • Balance sheet impact: CAPEX increases assets, OPEX reduces profit
  • Cash flow: CAPEX requires immediate outlay, OPEX distributed over time
  • Taxation: OPEX fully deducted in year, CAPEX deducted via depreciation
  • Metrics: EBITDA (earnings before interest, taxes, depreciation, amortization) doesn’t include CAPEX depreciation but includes OPEX

Historically, IT models were CAPEX-heavy (server purchase, perpetual licenses). Cloud shifted toward OPEX (pay-as-you-go). This shift transformed IT economics and business strategies.

How it Works

CAPEX vs OPEX classification follows accounting principles (IFRS, GAAP) with precise rules.

CAPEX Classification Criteria

A cost is CAPEX if it meets all criteria:

  1. Long-term benefit: Generates value beyond 1 year
  2. Tangible or intangible: Physical asset (building) or IP (developed software)
  3. Capitalizable: Exceeds minimum threshold (materiality threshold)
  4. Ownership or control: Company owns or controls the asset

CAPEX Examples:

  • Production machinery purchase: 500,000 euros
  • Data center construction: 10,000,000 euros
  • Perpetual software licenses: 200,000 euros
  • Internal software development: 300,000 euros (if capitalizable)
  • Company vehicles: 150,000 euros

Depreciation: CAPEX are allocated over asset useful life. Methods: Straight-line (constant), accelerated (more in early years), units of production. Server with 5-year life and 100K cost: 20K/year straight-line depreciation.

OPEX Classification Criteria

A cost is OPEX if:

  1. Consumed in period: Benefit exhausted within fiscal year
  2. Recurring: Ongoing expenses to operate
  3. Non-capitalizable: Below threshold or doesn’t generate asset

OPEX Examples:

  • Salaries and wages
  • Office rent
  • Utilities (energy, water)
  • Cloud subscriptions (AWS, Azure)
  • Maintenance and repairs
  • Marketing and advertising
  • Travel and expenses

Recognition: OPEX impacts P&L (profit and loss) in the year. 100K salaries reduces EBIT by 100K.

Gray Areas and Special Cases

Maintenance: Ordinary is OPEX, extraordinary (improves asset) is CAPEX. Changing car oil is OPEX, replacing engine is CAPEX.

Software: Perpetual license is CAPEX (capitalized, amortized), subscription (SaaS) is OPEX. Internal development: Research phase is OPEX, development phase capitalizable if meets criteria (IAS 38).

Leasing: Depends on contract structure. Operating lease is OPEX (rent), finance lease (transfers ownership) is CAPEX. IFRS 16 (2019) requires capitalizing many leases previously OPEX.

Cloud migration: Migrating on-premise workloads (CAPEX) to cloud (OPEX) is strategic shift. Reduces CAPEX but increases OPEX. Net cash flow impact depends on details.

Use Cases

IT Transformation: On-Premise to Cloud

A traditional company operates on-premise data center. CAPEX model:

  • Server purchase every 3-5 years: 5,000,000 euros (CAPEX)
  • Annual depreciation: 1,000,000 euros
  • Maintenance, energy, staff: 2,000,000 euros/year (OPEX)
  • Annual P&L cost: 3,000,000 euros

Migrates to AWS. OPEX model:

  • Cloud subscription: 4,000,000 euros/year (OPEX)
  • Reduced staff (cloud management): 500,000 euros/year (OPEX)
  • Annual P&L cost: 4,500,000 euros

P&L cost increases 50%, but eliminates 5M upfront CAPEX. For startups with limited capital, OPEX is preferable. For enterprises with available cash, CAPEX can be more economical long-term.

Manufacturing: Purchase vs Leasing Machinery

A manufacturing company needs 10 CNC machines.

Purchase Option (CAPEX):

  • Cost: 5,000,000 euros
  • Depreciation (10 years): 500,000 euros/year
  • Maintenance: 200,000 euros/year (OPEX)
  • Year 1 impact: -5M cash flow, -700K P&L, +5M asset

Leasing Option (OPEX):

  • Leasing fee: 700,000 euros/year (OPEX)
  • Maintenance included
  • Year 1 impact: -700K cash flow, -700K P&L, no asset

Leasing preserves capital (no upfront 5M) and offers flexibility (easier upgrade). Purchase offers ownership and lower total long-term cost. Decision depends on: Capital availability, tax strategy, technology innovation speed.

SaaS vs Perpetual Licenses Software

A company acquires ERP for 500 users.

Perpetual licenses (CAPEX model):

  • Licenses: 2,000,000 euros (CAPEX)
  • Implementation: 500,000 euros (CAPEX)
  • Annual maintenance (18%): 360,000 euros/year (OPEX)
  • Year 1: -2.5M CAPEX, -360K OPEX
  • 5-year TCO: 2.5M + (360K × 5) = 4.3M

SaaS subscription (OPEX model):

  • Subscription: 100 euros/user/month = 600,000 euros/year (OPEX)
  • Implementation: 200,000 euros (can be OPEX or CAPEX)
  • Year 1: -800K OPEX
  • 5-year TCO: 3.2M

SaaS has lower TCO and zero CAPEX, but higher annual P&L cost (800K vs 360K after year 1). For companies wanting to minimize CAPEX (e.g., pre-revenue startups), SaaS is preferred. For companies with profitability to protect, perpetual licenses reduce long-term P&L impact.

Real Estate: Purchase vs Rent

A company needs 2,000 sqm office space.

Purchase (CAPEX):

  • Property cost: 5,000,000 euros (CAPEX)
  • Renovation: 500,000 euros (CAPEX)
  • Annual maintenance: 100,000 euros (OPEX)
  • Depreciation (30 years): 183,000 euros/year
  • Year 1: -5.5M cash, -283K P&L, +5.5M asset

Rent (OPEX):

  • Rent: 300,000 euros/year (OPEX)
  • Year 1: -300K cash, -300K P&L

Purchase requires significant capital but creates appreciable asset. Rent offers flexibility (easier relocation) and no real estate risk. Decision depends on: Long-term location strategy, capital opportunity cost, real estate market conditions.

Startups: Optimizing Cash Flow

A pre-revenue startup has 2M euros funding. Priority: Maximize runway (months before cash exhaustion).

CAPEX-heavy scenario:

  • Server, license purchases: 500K CAPEX
  • Salaries, rent: 100K/month OPEX
  • Runway: (2M - 500K) / 100K = 15 months

OPEX-only scenario:

  • Cloud, SaaS: 30K/month OPEX
  • Salaries, rent: 100K/month OPEX
  • Runway: 2M / 130K = 15.4 months

OPEX-only has similar runway but greater flexibility (rapid scaling up/down). CAPEX requires upfront commitment, risky if pivot needed. For startups, minimizing CAPEX is dominant strategy.

Practical Considerations

Tax Impact and Planning

Different tax treatments of CAPEX and OPEX influence decisions:

  • OPEX: Fully deducted in year, reduces taxable income immediately
  • CAPEX: Deducted via depreciation, tax benefit distributed over years

Example: Company with 30% tax rate.

  • 100K OPEX: Year 1 tax savings = 30K
  • 100K CAPEX depreciated over 5 years: Tax savings = 6K/year for 5 years

In NPV terms, OPEX has advantage (time value of money). But some jurisdictions offer incentives for CAPEX (e.g., super-depreciation for technology innovation, R&D credits).

In Italy, from 2020-2025 “super-depreciation” of 140-270% was available for Industry 4.0 capital goods investments, incentivizing CAPEX.

Balance Sheet Optimization

CAPEX/OPEX ratio impacts financial metrics:

  • Asset-light strategy: Reducing CAPEX improves ROA (return on assets), frees capital
  • EBITDA: Shifting from CAPEX to OPEX reduces EBITDA (depreciation doesn’t impact EBITDA, OPEX does)
  • Debt covenants: Some covenants limit CAPEX, making OPEX preferable

Capital-intensive companies (manufacturing, telco) have high CAPEX. Asset-light companies (consulting, SaaS) operate mainly on OPEX. Cloud trend is transforming many sectors toward asset-light.

Strategic Decisions and Flexibility

CAPEX vs OPEX choice has strategic implications:

CAPEX favors:

  • Complete asset control
  • Long-term economies (lower total cost)
  • Deep customization
  • IP protection (on-premise servers for sensitive data)

OPEX favors:

  • Flexibility (scaling, termination)
  • Continuous updates (SaaS always updated)
  • Cash flow predictability
  • Reduced technology risk (no obsolescence risk)

In rapid-change contexts (tech startups), OPEX reduces risk. In stable contexts (utilities, incumbents), CAPEX can be optimal.

Hybrid Models and FinOps

Many organizations adopt hybrid models:

  • Core systems: CAPEX (control, security)
  • Innovation/agile workloads: OPEX (cloud, flexibility)

FinOps (cloud financial management) emerges as discipline to optimize cloud OPEX. Includes: Rightsizing, reserved instances (OPEX commitment for discount), spot instances.

Common Misconceptions

”CAPEX is Always Better for Reducing Costs”

False. CAPEX often has lower total lifecycle cost, but:

  • Obsolescence risk: Technology evolves rapidly. Server bought today may be obsolete in 3 years.
  • Opportunity cost: Capital invested in CAPEX unavailable for other uses (e.g., hiring, marketing)
  • Lack of flexibility: If business pivots, CAPEX assets become stranded (sunk cost)

In cloud era, OPEX offers agility that compensates for higher cost. A startup scaling from 10 to 100 users in 6 months couldn’t do so with CAPEX (buying servers requires lead time).

”Cloud is Always OPEX”

Not necessarily. Some cloud models have CAPEX elements:

  • Reserved instances: 1-3 year commitment, upfront payment, 30-70% discount. Can be capitalized.
  • Colo + cloud hybrid: Data center space rent (OPEX) + hardware purchase (CAPEX)

Additionally, cloud migration may require initial CAPEX (re-architecting apps, data migration).

”OPEX Doesn’t Impact Balance Sheet”

OPEX indirectly impacts balance sheet by reducing profits (equity). Moreover, IFRS 16 requires capitalizing operating leases, bringing OPEX into balance sheet as liability.

A multi-year cloud subscription may be accounted as liability if commitment is irrevocable. This reduces the sharp CAPEX/OPEX distinction.
