What Is Capex?
Updated
Definition
Capex (capital expenditure) is money spent to acquire or upgrade long-lived physical or infrastructure assets — recorded on the balance sheet and depreciated over time, rather than expensed immediately as opex.
Useful for: Founders, Investors
Capex (capital expenditure) is investment in long-term assets — equipment, infrastructure, buildings — capitalized on the balance sheet and depreciated over useful life.
How it works
Accounting treats capex differently from opex (operating expenditure) like payroll and rent. Spend $2 million on factory machines → capex asset depreciated over years. Spend $2 million on sales salaries → opex hits the P&L immediately.
In startups, capex appears in:
- Hardware and robotics companies buying production gear
- Data centers and climate projects building physical plants
- SaaS businesses capitalizing internal-use software development (under certain rules)
Cash flow statements show capex as investing outflows. Investors adjust burn rate analysis when capex drives growth — recurring opex burn may be low while cash capex drains the account.
Software capitalization rules vary by accounting policy — some engineering costs hit opex under GAAP while still feeling like investment to operators. Align with your CFO on definitions before reporting metrics to the board.
Investors in hardware-adjacent startups often ask for capex per unit deployed — tying capital intensity directly to customer revenue milestones.
Why it matters
- Founders: Separate capex plan from operating budget in board decks. Lenders may finance asset-heavy capex; pure VC may prefer asset-light models.
- Investors: Capex-heavy models need longer horizons, project finance, or PE-style returns. Misclassifying capex as opex distorts unit economics.
Common mistake
Ignoring maintenance capex — replacement equipment needed to sustain output — and modeling only growth capex. Both consume cash and belong in board-level capital planning.
