What is Capex vs. Opex?
Capital expenditure versus operating expenditure - why one hits the balance sheet and the other hits the P&L today.
Capex vs. Opex: definition
The distinction changes when a cost hits profit and how it looks to lenders and investors. A $30,000 server counted as capex barely dents this year profit - it depreciates over several years - while the same $30,000 spent on cloud hosting is opex and lowers profit immediately. Misclassifying the two distorts margins, EBITDA, and tax.
| Dimension | Capex | Opex |
|---|---|---|
| What it buys | Long-lived assets (equipment, buildings, capitalized software) | Day-to-day running costs (rent, salaries, SaaS) |
| Where it lands | Balance sheet, then depreciation/amortization | Income statement, this period |
| Profit impact | Spread over the asset useful life | Full hit now |
| Cash timing | Often large, upfront | Recurring, smaller |
How Fintra handles it
When you approve a bill in Fintra, the AI proposes whether the cost is capex or opex based on the vendor, amount, and account, and - for capex - sets up the fixed asset and its depreciation schedule in the same step. A named human confirms the classification before it posts, so the capitalize-or-expense call is deliberate rather than a month-end cleanup.
- AI suggests capex vs. opex at bill approval, with the reasoning shown
- Capitalized items open a fixed-asset record and depreciation schedule automatically
- A capex threshold policy flags small purchases that should just be expensed
Worked example
Frequently asked questions
Is a subscription capex or opex?
Most software subscriptions are opex - you pay to use software you do not own, so the cost is expensed each period. The main exception is internal-use software development you build and capitalize under ASC 350-40. Fintra classifies typical SaaS bills as opex by default and flags the rare capitalizable build costs for review.
Why do companies prefer opex over capex?
Opex is smaller, recurring, and easier to start or stop, which suits fast-moving or cash-constrained businesses - one reason cloud and subscriptions replaced big hardware buys. Capex ties up cash upfront but can be cheaper over an asset long life. The right mix depends on cash position, growth, and tax strategy.
Does capex affect EBITDA?
Not directly. EBITDA excludes depreciation, so capitalizing a cost keeps it out of EBITDA in the year you buy - which is why heavy-capex businesses can show strong EBITDA yet weak free cash flow. Opex reduces EBITDA immediately. Analysts watch capex separately to avoid being misled.
What is a capitalization threshold?
A dollar cutoff (often $1,000–$5,000 for SMBs) below which purchases are expensed even if technically long-lived, to avoid tracking trivial assets. Fintra lets you set the threshold as policy so small buys are expensed automatically and only material assets get capitalized.
