Buy or Lease That Equipment?
The Numbers That Decide It
The monthly payment is the wrong thing to compare — and deciding on it is how good contractors end up asset-rich and cash-poor. The four numbers that actually decide buy vs. lease: total cost of ownership, utilization, tax treatment, and the balance sheet your bonder reads.
The equipment dealer slides a number across the table — "it's only $2,400 a month" — and it feels affordable, so you sign. The trouble is the monthly payment was never the real question. That one friendly number hides the four that actually decide whether this machine makes you money or quietly drains it: what it truly costs over its life, how hard you'll use it, how it's taxed, and what it does to the cash and the balance sheet a bonding company is about to read.
A five- or six-figure decision made on the payment alone is exactly how good contractors end up asset-rich and cash-poor — or watch their bonding capacity shrink right when they need it to grow. We run the real numbers behind the payment, so the call protects your cash and your margin instead of the dealer's.

Quick Answer
- →Don't compare payments — compare total cost of ownership over the asset's whole life.
- →Heavy, long-life use favors buying. Light, short-term, or fast-obsolescing use favors leasing.
- →Section 179 and bonus depreciation can make buying very attractive in a high-income year — confirm current limits with the IRS or your tax advisor.
- →Both choices move your balance sheet — and a lender or surety reads that when they size your credit or bond.
The five factors that actually decide it
Salespeople anchor you on the payment because it's the easiest number to shrink. Ignore it. These five factors are what make the decision right or wrong over the life of the machine.
Cash flow & opportunity cost
Buying ties up cash (or borrowing capacity) in one asset. Leasing preserves that cash for payroll, materials, or the next job — but you pay for the privilege over time.
What to weigh
The question isn't just "can I afford it" — it's "what else could that cash be earning or protecting me from?"
Utilization — how hard you'll use it
How many hours, for how many years. A machine you run daily for a decade is a different decision than one you need for a single season.
What to weigh
Heavy, long-term use favors buying. Light, occasional, or seasonal use favors leasing or renting.
Tax treatment
Section 179 lets you expense qualifying equipment up to an annual limit; bonus depreciation is a separate accelerated write-off. Under the OBBBA changes in 2025, bonus depreciation treatment shifted — confirm the current percentage and limits.
What to weigh
In a high-income year, writing off a purchase can swing the math hard toward buying. Lease payments are generally deductible as you go — different timing, different benefit.
Total cost of ownership
The payment is one line. Owning adds maintenance, repairs, downtime, insurance, and eventual resale value. Leasing adds fees, mileage or hour overages, and return conditions.
What to weigh
Add it all up across the full term before you compare. The cheaper monthly number is often the more expensive deal.
Balance sheet & bonding impact
A purchase puts an asset — and usually a loan — on your books. A lease creates its own obligation. Both change the ratios a lender or surety reads.
What to weigh
Carrie's underwriting lens: owned equipment plus debt, or lease commitments, both affect how much credit or bonding capacity you'll get. Plan the financing with that in mind, not after.
When buying wins, and when leasing wins
Buying usually favors you when…
- →You'll use it heavily for years — a long-life core asset.
- →It holds resale value and the tech won't be obsolete soon.
- →You have a high-income year and can use Section 179 or bonus depreciation.
- →You have the cash or credit to buy without starving operations.
Leasing usually favors you when…
- →Use is light, seasonal, or short-term.
- →The equipment ages or obsolesces fast and you want to swap it.
- →Preserving cash matters more than long-run cost right now.
- →You want maintenance bundled and predictable payments.
A simplified five-year look
Illustrative| Buy (financed) | Lease | |
|---|---|---|
| Cash up front | Down payment + setup | First / last payment |
| Ongoing cost | Loan payment + upkeep | Lease payment + fees |
| Year-one tax | Possible large write-off | Payment deducted as paid |
| End of term | You own it — resale value | Return it or buy out |
| Balance sheet | Asset + loan on the books | Lease obligation |
Picture Dave's Excavation in Kalispell weighing a $120,000 machine. (Illustrative scenario.) The lease payment looks lighter month to month, but Dave runs it hard, year-round, for a decade — so over the full life, owning is cheaper, and in a strong-income year the Section 179 write-off tips it further. Flip the facts — a specialty machine he'd use a few weeks a season — and leasing or renting wins easily. Same contractor, opposite answer, because the use changed, not the payment.
The balance-sheet move most owners miss
This is where Carrie's underwriting background changes the conversation. When you buy on credit, you add an asset and a loan. When you lease, you add an obligation. Either way, a lender or a surety reads those numbers when they decide how much to lend you or how big a bond they'll write. Load up on equipment debt right before you need bonding capacity for a big job, and you can win the equipment but lose the work.
The right question isn't "buy or lease?" It's "which choice leaves my cash, my taxes, and my borrowing power in the best shape for what's coming next?" Run your specific numbers before you sign.

FAQ
Is buying always cheaper than leasing?
No — only usually, and only for the right asset. Buying tends to win on equipment you use heavily over a long life, because you own it at the end and capture any resale value instead of paying fees forever. But leasing can be cheaper in practice for equipment you use lightly, need only for a season, or that goes obsolete fast — and it preserves cash you might need more elsewhere. The honest answer is that it depends on utilization, cash position, and tax year, which is why you compare total cost of ownership, not the monthly payment.
What's the tax difference between buying and leasing?
Broadly, buying can let you accelerate the deduction: Section 179 expenses qualifying equipment up to an annual limit, and bonus depreciation is a separate accelerated write-off — the kind of thing that can sharply reduce tax in a high-income year. Bonus depreciation treatment changed under the OBBBA legislation in 2025, so confirm the current percentage and limits with the IRS or your tax advisor. Lease payments, by contrast, are generally deductible as you pay them — a smaller benefit spread over the term. Which one helps you more depends on your income this year and how the asset is financed. This isn't tax advice; run your specific numbers.
How does buying or leasing affect my ability to get a loan or bond?
Both show up on your financials and both matter to a lender or surety. A financed purchase adds an asset and a loan; a lease adds an obligation — and either can change the ratios an underwriter uses to size your credit or your bonding capacity. If you know a big, bond-dependent job is coming, the timing and structure of an equipment deal can protect or shrink the capacity you'll need. It pays to plan the financing with that in view rather than discover the tradeoff after you've signed.
