Key takeaways

• Opex covers day-to-day running costs like rent, wages, and utilities, while capex refers to longer-term investments in assets such as equipment, vehicles, and property.
• In many countries, opex is deducted from revenue in the year you spend it, reducing your taxable income straight away. Capex is recorded as an asset and depreciated over its useful life.
• Understanding the difference helps you plan cash flow, budget more accurately, and claim the tax deductions available to you. Some countries let you deduct qualifying assets faster, and the rules vary by country.
• Categorizing your expenses correctly from the start saves time at tax time and gives you a clearer picture of your business's financial health.

What is opex?

Opex (operating expenditure) is the money you spend to keep your business running on a daily basis. These are the recurring costs you pay regularly to maintain normal operations.

Think of opex as the expenses that would stop your business from functioning if you didn't pay them. Rent, employee wages, utility bills, insurance premiums, and office supplies all fall into this category. They're typically predictable and repeat on a monthly, quarterly, or annual cycle.

Opex doesn't include the cost of goods sold (COGS), which covers the direct costs of producing or purchasing what you sell. It also doesn't include one-off asset purchases, which fall under capex.

Common opex examples

Most of your regular business expenses are likely opex. Here are some of the most common ones for small businesses:

• Wages and salaries for your team
• Rent and lease payments for your premises
• Utility bills such as electricity, water, and internet
• Insurance premiums
• Marketing and advertising costs
• Software subscriptions and cloud services
• Accounting and legal fees

Opex appears on your profit and loss statement and on your cash flow statement under “cash flow from operations.” Because opex is subtracted from revenue, it directly affects your reported profit.

What is capex?

Capex (capital expenditure) is the money you spend on assets that will benefit your business for more than one year. These are typically larger, less frequent purchases that help you grow or maintain your operations over the long term. Under the international accounting standard IAS 16, equipment you expect to use for more than one period is generally recorded as an asset.

Unlike opex, capex isn't deducted from revenue in a single year. Instead, the cost is spread across the asset's useful life through depreciation. This means a capex purchase affects your finances differently from your everyday running costs.

Types of capex

Capex generally falls into two categories, each serving a different purpose:

• Maintenance capex: spending to keep your current operations running, such as replacing broken equipment or a worn-out delivery vehicle
• Growth capex: spending to expand or improve your business, such as buying additional equipment, fitting out a second location, or investing in new technology

Common capex examples

Capex purchases tend to be less frequent but higher in value. Here are examples you might encounter:

• Vehicles for deliveries or client visits
• Machinery and manufacturing equipment
• Computers, servers, and other IT hardware
• Office furniture and fit-outs
• Property or land purchases
• Major software systems bought outright (not subscriptions)

Capex appears on your balance sheet as an asset. Under IAS 7, the cash outflow shows up on your cash flow statement under “cash flow from investing activities.”

How to categorize expenses as opex or capex

Knowing whether an expense is opex or capex isn't always obvious. A simple set of criteria can help you categorize each purchase correctly and avoid mistakes at tax time.

An expense is generally capex if it meets all three of these conditions:

• It has a useful life of more than one year
• It costs more than the capitalization threshold your business uses
• It provides ongoing economic benefit to your business beyond the current financial year

Capitalization thresholds vary by country and by business policy. In the United States, a de minimis safe harbor lets you deduct up to $2,500 per invoice or item, or $5,000 with an applicable financial statement.

If an expense doesn't meet these criteria, it's most likely opex. For example, if your business sets its threshold at $2,500, a $200 keyboard is opex because it falls below that amount. A $5,000 computer is capex because it costs more than your threshold, lasts several years, and supports your daily operations over that time.

Some expenses sit in a gray area. Routine repairs that keep an asset in working order are usually opex, while improvements that extend its life or add value are typically capex. Under IAS 16, day-to-day servicing costs are expensed as you incur them.

In the United States, the Internal Revenue Service (IRS) generally treats bettering, restoring, or adapting an asset as an improvement you capitalize. If you're unsure, your accountant or bookkeeper can help you classify borderline items correctly.

Key differences between opex and capex

Opex and capex both represent money leaving your business, but they behave very differently in your accounts, your tax return, and your planning. Here's how they compare across the areas that matter most.

Time horizon

Opex covers short-term costs you'll consume within the current financial year. Capex involves longer-term investments in assets you'll use for more than one year.

This difference affects how quickly you can course-correct. If you overspend on a monthly expense like marketing, you can adjust next month. A poor capex decision, such as buying equipment you don't need, ties up cash for much longer.

Impact on profit

Opex is subtracted from your revenue when calculating profit. The higher your operating expenses, the more revenue you need to break even.

Capex doesn't reduce your profit in the year you spend it. Instead, depreciation spreads the cost across multiple years, with only the annual depreciation amount appearing on your profit and loss statement.

Flexibility and planning

Most opex is essential to keep your business running. Rent and wages need to be paid on time, every time.

Capex, on the other hand, often gives you more flexibility on timing. You can delay purchasing a new vehicle or upgrading equipment until your cash flow supports it.

Opex tends to follow a predictable pattern from quarter to quarter. Wages are a good example, since they usually change gradually through pay reviews and new hires. That kind of predictability makes it easier to plan your opex budget from one quarter to the next.

That said, maintenance capex can be urgent. If a critical piece of equipment breaks down, you may need to replace it immediately regardless of your budget.

How they appear on financial statements

Opex and capex show up in different places across your financial statements. Understanding where each one appears helps you read your reports more accurately.

• Opex appears on the profit and loss statement as an expense and on the cash flow statement under operating activities
• Capex appears on the balance sheet as an asset and, under IAS 7 investing rules, on the cash flow statement under investing activities
• Depreciation (the annual cost of capex assets wearing out) appears on the profit and loss statement as an expense

Tax treatment of opex and capex

How you classify an expense as opex or capex directly affects when and how you can claim a tax deduction. Rules, thresholds, and terminology vary by country, so check what applies where your business pays tax.

Deducting opex

In many tax systems, opex is deductible in full in the financial year you incur it, though the rules vary by country. For example, if you spend $10,000 on rent this year, you can usually claim the entire amount as a tax deduction against your taxable income for that year. This makes opex straightforward at tax time.

Depreciating capex

Capex is typically deducted over the useful life of the asset through depreciation. Tax authorities set recovery periods or useful-life schedules for different asset types, which determine how many years you spread the deduction across.

In the United States, the IRS generally treats computers as 5-year property and office furniture as 7-year property, according to IRS Publication 946. As a simple illustration, a laptop with a 4-year useful life means you'd deduct roughly 25% of its cost each year.

Accelerated deductions

Some countries let eligible businesses deduct the full cost of qualifying assets in the year of purchase, instead of depreciating them over time. This can improve your cash flow in the year you make the purchase.

The Organisation for Economic Co-operation and Development (OECD) reports that 90 of the 105 jurisdictions it covered for 2025 offer accelerated depreciation. Here's how it works in two of them:

• In the United States, the 2026 Section 179 limit is $2,560,000, and it starts to reduce once qualifying purchases exceed $4,090,000 (Rev. Proc. 2025-32)
• In the United States, 100% bonus depreciation was reinstated for qualified property acquired and placed in service after January 19, 2025 (IRS Notice 2026-11)
• In the United Kingdom, the Annual Investment Allowance lets you deduct up to £1 million of qualifying plant and machinery from your profits before tax

These figures are current as of October 2026, and eligibility rules change regularly. Check your local tax authority's website or speak with your accountant to confirm the current limits before claiming.

Budgeting for opex and capex

Planning your spending across opex and capex helps you manage cash flow and avoid surprises. Each type of expense calls for a different budgeting approach.

Budgeting for opex

Because opex tends to be predictable, you can budget for it using your historical spending data. Review your past 12 months of operating expenses and look for patterns. Factor in any expected changes, such as a rent increase or a new hire, and build a monthly forecast you can track against actual spending.

Budgeting for capex

Capex is harder to predict because it often depends on opportunity, equipment condition, or growth plans. Create a separate capex budget that lists planned asset purchases for the coming year, along with estimated costs and timing. Prioritize items based on urgency and expected return.

Considering capex-to-opex strategies

You don't always have to buy assets outright. Subscription-based software turns what would be a large upfront capex payment into smaller, regular opex payments. This can help you preserve cash flow, especially in the early stages of your business or during periods of uncertainty.

Leasing also spreads the cost, but its accounting treatment depends on your framework. Under International Financial Reporting Standards (IFRS), IFRS 16 puts most leases longer than 12 months on your balance sheet, unless the asset is low value.

For example, leasing a vehicle instead of buying one spreads the cost over monthly payments instead of a lump sum. Whether those payments count as opex depends on the lease term, your accounting framework, and local tax rules, so check with your accountant.

FAQs on opex vs capex

Here are answers to some frequently asked questions about opex vs capex.

Is depreciation opex or capex?

Depreciation itself is an operating expense that appears on your profit and loss statement. It represents the annual cost of a capex asset losing value over time, so it connects the two categories.

Is software opex or capex?

It depends on how you acquire it: subscriptions and cloud services are opex because you pay ongoing fees. Software you purchase outright with a license you own is typically capex because it's an asset with a useful life beyond one year.

Can you convert capex to opex?

Sometimes: subscriptions are generally opex, while lease treatment depends on your accounting framework and local tax rules. Check with your accountant to confirm what applies to you.

What is an example of an opex expense?

Monthly rent for your office or workspace is a common opex expense. It's a recurring cost that keeps your business running but doesn't create a long-term asset on your balance sheet.

What is an example of a capex expense?

Buying a delivery vehicle for your business is a typical capex expense. The vehicle is an asset you'll use for several years, so its cost is usually depreciated over its useful life unless an accelerated deduction applies.
