# What Is Capex?

> 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.

**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](/glossary/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](/glossary/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.

## FAQ

### What is capex in simple terms?

Capex is spending on big, long-lasting assets — servers, manufacturing equipment, buildings — that you capitalize on the balance sheet instead of counting fully as this month's expense.

### Why does capex matter?

For founders, heavy capex changes cash needs and fundraising story. For investors, it affects scalability, margins, and whether venture equity is even the right capital type.
