What Contractors Should Review Before Buying Equipment

Buying equipment feels like progress. It is also the decision most likely to convert a profitable year into a tight one, because the money leaves on a fixed schedule while the work that justifies it does not arrive on any schedule at all.

The useful question is not whether the machine is good, or even whether you can afford the payment. It is how many days a year the thing will actually be on a job — and what the alternatives cost at that level of use.

Start With Utilization, Not Capability

Almost every equipment purchase is justified by capability: this lets us take on work we currently sub out, or finish faster, or stop renting. All of that can be true and the purchase can still be wrong.

Capability is worth paying for in proportion to how often you use it. Before anything else, write down an honest number:

• How many days last year would you have used this, based on jobs you actually ran — not jobs you hope to win?
• Of those days, how many were on work that cleared a decent margin?
• Is the demand steady through the year, or concentrated in a few months when everything happens at once?

If the honest answer is "a couple of weeks a year," you are not evaluating a purchase. You are evaluating a rental, and the rest of this becomes much simpler.

Price the Machine Over Its Life, Not at the Counter

The purchase price is the smallest commitment you make. Total cost of ownership over the years you will hold it includes:

• Purchase price or the amount financed
• Interest over the full term
• Insurance, which is a new line on your policy, not a rounding error
• Maintenance, wear parts, and the repair you have not budgeted for
• Transport between jobs, and somewhere to keep it
• Training, certification, or an operator you do not currently employ
• What it will be worth when you are done with it

Take a $85,000 machine financed over 60 months at 8%. The payment is about $1,723 a month — roughly $20,700 a year, and about $18,400 of interest across the full term. Add illustrative carrying costs of $1,200 insurance, $2,500 maintenance, and $1,200 transport and storage, and the real annual cost of having it available is close to $25,600.

That $25,600 is the number to compare against alternatives. The $85,000 is not.

Find the Utilization Break-Even

Once you have an annual cost of ownership, the rent-versus-buy question stops being a matter of opinion and becomes one division problem.

If a comparable machine rents for $650 a day, the break-even is:

$25,600 ÷ $650 = about 39 days a year

Below roughly 40 days of use, renting is cheaper — and it is cheaper in a way that does not consume borrowing capacity, does not add an obligation that survives a slow quarter, and hands the maintenance risk to someone else. Above it, ownership starts to pay, and the further above it you are the more it pays.

Run this with your own numbers. The rental rate, the financing terms, and the carrying costs are all specific to you, and the break-even moves substantially when any one of them does. What does not change is the shape of the answer: the decision is a utilization threshold, and you can calculate it.

Consider the Options Between Renting and Buying New

Rent and buy-new are the two ends of a range, and the middle is where a lot of good decisions live:

• Rent for specific jobs. Best below the break-even, and the rental cost is chargeable to the job it belongs to, which keeps your job costing honest.
• Rent with a purchase option. Turns the first several months into paid evaluation, at a premium.
• Buy used. Takes the steepest part of the depreciation curve off the table. The trade is unknown maintenance history and no warranty — worth a pre-purchase inspection you pay for yourself.
• Lease. Lower monthly cost and a predictable exit, at the price of never owning the asset. Sensible where the technology moves or the work is project-based rather than continuing.
• Sub out the scope entirely. If the equipment exists to serve one part of the work, a subcontractor may be the cheaper answer permanently.
• Delay. If the case rests on a backlog you have not signed, waiting one quarter costs almost nothing and removes most of the risk.

Test the Payment Against Your Cash Flow, Not Your Profit

Equipment purchases fail on cash, not on profit. A machine can be genuinely accretive to margin and still put you in trouble, because the payment starts immediately and construction receivables do not.

Before signing, look at:

• Your current cash position, and the low point you have hit in the last twelve months
• When the jobs backing this purchase actually collect — including retainage, which is often released long after substantial completion and is a common reason a profitable job runs a business short of cash. The mechanics are in retainage and progress payments.
• Existing debt payments and how much room is left
• Whether the new payment survives a quarter where one large receivable slips

If the purchase only works assuming collections land on time, the assumption is the risk, not the equipment. A 13-week rolling cash flow forecast will show you the low point before you commit to it rather than after.

The Tax Rules Are Settled — Which Removes the Year-End Rush

For years, equipment timing carried a real tax argument, because bonus depreciation was stepping down and buying earlier was worth more than buying later. That argument is largely gone.

• 100% bonus depreciation is permanent under IRC §168(k) for qualified property acquired after January 19, 2025 — the One Big Beautiful Bill Act made it so, and the IRS set out the mechanics in Notice 2026-11.
• Section 179 expensing for tax years beginning in 2026 is capped at $2,560,000, phasing out dollar-for-dollar once §179 property placed in service exceeds $4,090,000 (Rev. Proc. 2025-32).
• One cap catches contractors buying trucks: a sport utility vehicle is limited to $32,000 under §179(b)(5)(A), regardless of the general cap.

Because full expensing is permanent rather than expiring, "buy it before the rules change" is no longer a reason to move. What still matters is placed in service, not purchased — a machine paid for on December 28 but still on a delivery truck generates no current-year deduction — and your own income in the year you take it. The deduction is worth more in a high-income year than a thin one.

The full year-end sequence is in our year-end tax planning checklist for Florida contractors, and the broader set of changes is covered in what the OBBBA changed for South Florida business owners.

The rule underneath all of it: a deduction returns a fraction of what you spend. It can improve a purchase that already makes sense. It cannot rescue one that does not.

A Pre-Purchase Checklist

Before you commit, confirm each of these has an actual number behind it:

1. Days of use per year, based on jobs you ran, not jobs you hope for
2. Total annual cost of ownership, including interest, insurance, maintenance, transport, and storage
3. The utilization break-even against the rental rate
4. Which alternative — rent, used, lease, sub out, delay — you actually compared it to
5. The effect of the payment on your worst cash week, not your average one
6. Whether the equipment will be placed in service in the year you want the deduction
7. The hourly cost of the crew who will run it, which is usually higher than assumed — see what an hour of crew time actually costs

How KDM Accounting Services Can Help

We help Florida contractors put numbers behind larger purchases before the paperwork is signed. That typically means:

• Building the total cost of ownership and the utilization break-even
• Testing the payment against a rolling cash flow forecast rather than a good month
• Clarifying how §179 and bonus depreciation apply to the specific asset and your income year
• Comparing financing, leasing, used, and rental on the same basis
• Making sure the purchase shows up correctly in job costing afterward

Buy With Clarity

New equipment is a good investment when it is used enough to beat the alternatives and the payment fits the cash you will actually have. Both of those are calculations, and both can be done in an afternoon before you commit.
