CapEx vs OpEx
Why Two Expenses Hit Profit in Different Ways

Renata Vasquez spent $96,000 on a canning line in March.

She runs Ironwood Brewing Co., a fourteen-barrel craft brewery in Grand Rapids that self-distributes across western Michigan. Before that, every batch went out to a mobile canning crew. The new line cut her packaging turnaround from nine days to two and let her land two more distributor accounts by summer.

Then April closed, and her profit and loss statement made no sense to her.

Net income for the quarter came in at $41,000. This was higher than the same quarter last year. Meanwhile, her operating account had dropped to under $19,000, and payroll was Friday. She called her accountant, convinced the books were wrong.

The books were fine. The canning line was a capital expenditure, and capital expenditures do something that catches almost every owner off guard the first time: they take your cash immediately and touch your profit slowly. Let’s learn more about this today.

The line that separates the two

Every dollar a business spends lands in one of two buckets, and the bucket decides which financial statement the spending shows up on.

Capital expenditures, or CapEx, are purchases of assets that will serve the business for more than one year. Examples of CapEx include machinery, vehicles, buildings, leasehold improvements, and computer hardware. These get capitalized, meaning they land on the balance sheet under property, plant, and equipment (PP&E). The income statement only sees the cost in slices, through depreciation, spread across the asset's useful life.

Operating expenditures, or OpEx, are the recurring costs of running the business day-to-day. Rent, wages, utilities, insurance premiums, hops and grain, software subscriptions, and repairs that keep an asset working at its current condition. These hit the income statement in full, in the period they are incurred, and reduce taxable income right away.

What Renata's accountant actually drew on the napkin

Ironwood had a second option in March. A leasing company offered the same line on a five-year operating lease at $1,900 a month. Same machine, same productivity gain, but completely different accounting.

Straight-line depreciation on the purchase looks like this:

Annual depreciation = (Cost − Salvage value) ÷ Useful life

($96,000 − $0) ÷ 8 years = $12,000 per year

So the purchase costs Renata $96,000 in cash in year one and $12,000 in reported expenses. The lease costs her $22,800 in cash in year one and $22,800 in reported expenses. Same equipment, opposite pressure points.

Year one's reported profit looks better under the purchase method. The year-one bank balance looks dramatically worse. This gap is the reason Renata's P&L and her checking account told two different stories, and it explains how a profitable business can still miss payroll.

Where the line actually gets drawn

No accounting rule specifies a universal dollar amount that qualifies an expense as CapEx. Every company sets its capitalization threshold as part of its accounting policy, and auditors care that you apply it consistently. Small businesses commonly set thresholds between $500 and $2,500. Mid-market companies often land between $2,500 and $10,000.

Repairs versus improvements is where owners get tripped up most. Replacing a worn conveyor belt on the filler keeps the machine at its current condition, so it is a repair that gets expensed. Retrofitting the same line with a nitrogen dosing unit and new seamer heads that add four years of service life extends the asset, so it gets capitalized and depreciated. Aggregation matters too. Twenty laptops at $800 each individually fall under a $2,500 threshold, but a $16,000 batch order may require capitalization.

The tax code bends the rule on purpose

Book accounting and tax accounting diverge here, and the difference benefits a small business owner. Section 179 of the Internal Revenue Code lets qualifying businesses deduct the full purchase price of eligible equipment in the year it is placed in service, subject to annual dollar caps and a phase out once total purchases pass a threshold. Bonus depreciation offers a similar acceleration on top of it.

Renata still records $12,000 of depreciation on her books each year, because that is what matches the asset's useful life and what her lender wants to see. On her tax return, a Section 179 election could deduct a far larger share of the $96,000 in year one. There are two sets of numbers, both correct, that serve different readers. Confirm eligibility with your CPA before assuming a purchase qualifies.

Reading CapEx off statements you already have

You can calculate what a business spent on capital assets in a period without a fixed asset schedule in front of you:

CapEx = Ending PP&E − Beginning PP&E + Depreciation expense

Ironwood started the year with $140,000 in PP&E, ended with $224,000, and recorded $12,000 of depreciation. That gives $224,000 − $140,000 + $12,000, or $96,000. The canning line, right there.

This calculation matters when you are reading a competitor's filings, evaluating an acquisition target, or explaining to a lender why your cash dropped while your margins held.

The trap sitting on both sides

Heavy CapEx builds owned assets and lowers reported expense in the short run, and it locks up cash you cannot get back quickly. Selling a used canning line takes months, and rarely at the price you paid.

Heavy OpEx preserves liquidity and gives an immediate tax deduction, and it quietly compounds. Renata's lease would have cost $114,000 over five years for a machine she would never own. The same trap runs through software spending, where monthly subscriptions feel painless until the annual total lands.

Most businesses end up running both deliberately. Buy the assets that anchor your capacity. Lease or subscribe for the pieces that change fast or scale unpredictably.

The takeaway

Profit tells you what the period earned. Cash tells you what the period cost. A capital expenditure is the one purchase that guarantees those two numbers will disagree, and knowing which bucket a decision falls into before you sign is what keeps the disagreement from becoming a surprise.
