Capital Expenditure (CapEx)

What is capital expenditure?

Capital expenditure (CapEx) is money a business spends to buy, upgrade, or maintain physical assets like buildings, equipment, vehicles, or technology that will be used for more than one year.

Key takeaways

• CapEx is spending on assets that last multiple years, like a building, a truck, or a computer system.
• Unlike regular expenses, you usually can't deduct the full cost in the year you buy it.
• It shows up on the balance sheet as an asset, not all at once on the income statement.
• The cost is depreciated over time, meaning you deduct a portion each year based on the asset's useful life.
• Tracking CapEx separately from operating expenses gives you a clearer picture for planning.

How it works

Buying a long-term asset is an investment, not a one-time cost. Say you own a landscaping business and buy a $40,000 truck. It isn't used up in a year like gas or wages. It will help you earn money for years, so the tax rules generally have you spread the deduction over its useful life instead of taking it all at once.

The simplest method is straight-line depreciation:

Annual depreciation = (Purchase price − Salvage value) ÷ Useful life

Example 1: Coffee shop equipment

You spend $30,000 on espresso machines, grinders, and refrigeration that you expect to last 7 years. With straight-line depreciation and no salvage value, you deduct about $4,286 a year for 7 years. The equipment shows as an asset on your balance sheet and its book value shrinks each year.

Example 2: Tech company servers

A software company buys $100,000 of servers with a 5-year life. It deducts $20,000 a year, and after 5 years the equipment is fully depreciated on the books.

Example 3: Factory expansion

A manufacturer builds a $2 million addition to its factory. Commercial buildings are generally depreciated over 39 years for tax purposes, so the deduction is about $51,282 a year. The tax benefit is spread thin, but the asset stays on the balance sheet for a long time.

These are simplified examples. Tax depreciation often uses different methods and schedules, so check with a tax professional.

CapEx vs. OpEx

Gray area: repairs vs. improvements

• Repairs (OpEx): Fixing a broken AC unit, replacing worn tires, patching a roof leak. These keep the asset working and are generally deductible right away.
• Improvements (CapEx): Installing a new AC system or replacing the entire roof. These add value or extend the asset's life and generally must be capitalized.

Rule of thumb: if it maintains the asset, it's a repair. If it makes the asset better or last longer, it's an improvement.

Common types of CapEx

• Property and buildings: land, commercial real estate, construction, major renovations.
• Equipment and machinery: production lines, restaurant kitchens, medical devices, construction tools.
• Vehicles: company cars, delivery trucks, forklifts, trailers.
• Technology: computers, servers, network equipment, point-of-sale systems.
• Furniture and fixtures: office furniture, display cases, shelving.

Many businesses set a capitalization threshold. Items below it are expensed immediately even if they last more than a year. A cheap desk is typically an expense, while a $50,000 conference room buildout is CapEx.

Why tracking CapEx matters

• Tax planning: Depreciation schedules affect when you get deductions, and the timing of a big purchase can shift which tax year it lands in.
• Financial health: Investors and lenders look at CapEx to see whether a business is expanding or just replacing aging equipment.
• Cash flow: Big purchases drain cash fast, so plan them in advance and line up savings or financing.
• Budget accuracy: Separating CapEx from OpEx shows your true ongoing operating costs, which helps with pricing and margins.

CapEx and free cash flow

Analysts subtract CapEx from operating cash flow to see how much cash a business really has left after maintaining or growing its assets.

Free cash flow = Operating cash flow − Capital expenditures

Section 179 deduction

Normally CapEx is depreciated over years, but Section 179 of the tax code lets eligible businesses deduct the cost of qualifying equipment right away, up to an annual dollar limit. The limit and the phase-out threshold change, so check the current figures in IRS Publication 946.

A few rules that generally apply:

• Qualifying property includes most tangible business equipment, new or used, such as machinery, vehicles, computers, off-the-shelf software, and furniture.
• The equipment must be used more than 50% for business.
• The deduction can't exceed your business income for the year. Unused amounts can be carried forward.
• The deduction shrinks once total qualifying purchases pass a phase-out threshold.

Example

Your business buys $80,000 of qualifying equipment with a 5-year life. Without Section 179, straight-line depreciation gives you $16,000 a year for 5 years. With Section 179 (assuming you're under the limit and have enough business income), you could deduct the full $80,000 in year one.

Recapture

If you sell Section 179 property early, or its business use drops to 50% or below, you may have to recapture part of the deduction and pay tax on it. Limits and rules change, so review the current IRS guidance or talk to a tax professional.

FAQs

What's the difference between CapEx and OpEx?

CapEx buys long-term assets that last multiple years, like a building. OpEx covers day-to-day operations, like rent, utilities, and salaries. CapEx goes on the balance sheet and is depreciated over time. OpEx is deducted as it's incurred.

Can I deduct capital expenditures on my taxes?

Usually not all at once. You depreciate the asset over its useful life and deduct a portion each year. Section 179 can let eligible businesses deduct qualifying equipment immediately, up to the current IRS limit. Check with a tax professional for your situation.

How long does an asset need to last to count as CapEx?

Generally more than one year, and it usually needs to cost more than your business's capitalization threshold. Items below that threshold are typically expensed.

Should I buy or lease equipment?

Buying is CapEx: a big upfront cost, but you own the asset and can depreciate it. Leasing is usually treated as an ongoing expense, with smaller payments and no ownership. Buying tends to make sense for equipment you'll use for a long time. Leasing can make sense when you need flexibility, want to preserve cash, or expect the technology to become outdated quickly.

What depreciation method should I use?

Straight-line (the same deduction each year) is the simplest and common for financial statements. For taxes, most businesses use MACRS, which allows larger deductions in the early years. Many businesses use one method for their books and another for taxes. A tax professional can help you choose.

How do I budget for capital expenditures?

Keep a separate CapEx budget from your operating budget. Track the age and condition of your assets, plan replacements a few years ahead, and set money aside monthly so a major breakdown doesn't catch you off guard.

What if I finance a capital purchase?

The full purchase price is still CapEx, even if you finance it. You depreciate based on the total cost. Loan interest is typically deductible as a business expense, but principal payments are not. They just reduce what you owe.
