Lease vs Buy: How to Actually Decide (2026)

Leasing looks cheaper every month. Buying looks expensive upfront. Neither impression tells the whole story. The real question is which option costs less once you account for depreciation tax benefits, total payments over the asset's life, and the time value of your money — and the answer varies substantially depending on your tax situation, how long you plan to use the equipment, and what happens at the end of the term.

Why monthly payments mislead you

A lease payment is designed to feel manageable. It is smaller than a loan payment for the same piece of equipment because you are not paying for the full value of the asset — only its depreciation over the lease term, plus a financing charge. But "smaller payment" is not the same as "lower total cost."

When you add up every lease payment over the term and compare it to what you would have paid in principal, interest, and taxes on a purchase, the numbers often surprise people. A series of back-to-back leases on fast-depreciating equipment can cost significantly more over ten years than buying the equipment once, running it past the loan payoff, and using it for free during its remaining useful life. The opposite can also be true — especially when the equipment you would have bought becomes obsolete before you can extract that "free" period of use.

The only way to cut through the noise is to compare after-tax, net present value (NPV) costs for both paths. That is what this guide walks through.

The two types of lease and why the difference matters

Not all leases work the same way on your tax return, which changes the cost comparison meaningfully.

An operating lease — the traditional kind where you return the equipment at the end — lets you deduct the full lease payment as a business operating expense in the year you pay it. There is no asset on your balance sheet. You simply expense it like rent. This is tax-efficient on a year-by-year basis, but you build no equity and own nothing at term end.

A capital lease (also called a finance lease or $1-buyout lease) is treated more like a purchase. The asset and a corresponding liability go on your balance sheet. Tax deductions come from depreciation on the asset and the interest portion of the implied financing cost — not from the full payment itself. The practical effect: year-one deductions are smaller than an operating lease but you are building toward ownership. At the end, you buy the asset for a nominal amount.

When people loosely say "leasing vs. buying," they usually mean an operating lease versus an outright purchase with a loan. That is the comparison this guide focuses on.

The buying side: where depreciation changes everything

When you buy business equipment, the sticker price is not your real net cost. Federal tax law allows you to deduct the cost of qualifying equipment through depreciation, and in 2026 the rules are unusually generous.

Section 179 (IRC §179) lets businesses deduct the full purchase price of qualifying equipment in the year it is placed in service rather than spreading the deduction over the asset's useful life. For tax year 2026, the Section 179 limit is $2,560,000 — raised from the prior $1.25 million cap by the One Big Beautiful Bill Act (OBBBA §70306) and now indexed for inflation annually per IRS Rev. Proc. 2025-32. The phase-out begins at $4,090,000 in total equipment purchases. There is one important constraint: Section 179 deductions cannot exceed your business taxable income for the year (IRC §179(b)(3)), so a loss-year business cannot use it to deepen that loss.

Bonus depreciation (IRC §168(k)) handles what Section 179 cannot. It applies to the remaining cost basis after Section 179 is taken, has no taxable income cap, and can create or increase a net operating loss that carries forward. The OBBBA permanently restored 100% bonus depreciation for qualifying property acquired after January 19, 2025 — superseding the TCJA phase-down that had scheduled 20% for 2026. Combined, these two provisions mean many equipment purchases can be fully deducted in Year 1, turning a five- or seven-year depreciation wait into an immediate tax savings.

The leasing side: simplicity at a premium

On the lease side, the math is more straightforward: you pay a fixed monthly amount, deduct it as an operating expense (at your tax rate), and hand the equipment back at end of term. There is no salvage value to you, no depreciation planning, and no residual-value risk.

Lease pricing has two hidden components that do not appear in marketing materials. The first is the residual value — the lessor's estimate of what the equipment will be worth at term end. A higher residual value means lower monthly payments (you are financing less depreciation), but it also means the lessor, not you, captures that value at the end. The second is the money factor, which is the lease equivalent of an interest rate. To convert a money factor to an approximate annual interest rate, multiply by 2,400. A money factor of 0.003 is roughly equivalent to a 7.2% annual rate — comparable to equipment loan rates in mid-2026.

Because operating lease payments are fully deductible, the after-tax monthly cost is simply: Monthly Payment × (1 − Tax Rate). A $2,000 payment at a 25% tax rate costs $1,500 after tax. Straightforward — but that is the entire point of the comparison. Buying involves front-loaded deductions that reduce early-year costs but require capital and credit.

Fully worked example: $100,000 piece of equipment, 2026

Consider a manufacturing business buying a $100,000 CNC machine with a five-year useful life and an estimated $8,000 salvage value. The business has a 25% combined tax rate, a 8% discount rate (cost of capital), and enough taxable income to absorb a full Section 179 deduction.

Change one input and the conclusion can flip. If the business expects this equipment to be obsolete in three years rather than five, or if it has no taxable income to absorb Section 179, the lease may come out ahead. That is why the numbers matter more than a rule of thumb.

When buying tends to win

The purchase path has a structural advantage whenever the tax benefits are large relative to the financing cost. These conditions tend to favor buying:

• High and stable taxable income. Section 179 and bonus depreciation are most valuable when you have income to shield. A business earning $400,000 per year gets far more from a $100,000 Year 1 deduction than one that barely turns a profit.
• Long useful life, slow depreciation. Equipment that lasts 8–10 years after the loan is paid off gives you years of free use that a leasing path never provides. Heavy manufacturing equipment, commercial vehicles, and certain agricultural machinery often fall here.
• High residual value at end of term. If the equipment holds value well, you can sell it or continue using it. A lease gives you none of that upside.
• Access to attractive financing. Low-rate equipment loans (under 7%) with manageable down payments reduce the advantage of the lease's smaller monthly outlay.

When leasing tends to win

Leasing is not always losing. It is the better call in several common scenarios:

• Technology that becomes obsolete quickly. Computers, servers, medical imaging equipment, and diagnostic tools often have a useful life measured by when a better generation arrives — not by mechanical wear. Leasing lets you upgrade at term end without the problem of selling aging equipment at a loss.
• Limited taxable income or startup phase. If your business is not yet profitable, Section 179 is unavailable (though bonus depreciation still is). A lease payment that is fully deductible as an operating expense may deliver similar tax benefit with less complexity and no down payment.
• Capital preservation. A lease requires little or no upfront cash. For a growing business where every dollar of working capital is deployed in inventory, marketing, or hiring, the lower cash outlay at signing has real value even if the total cost is slightly higher.
• Off-balance-sheet simplicity. Smaller businesses that do not need to present audited GAAP financials often prefer the administrative simplicity of operating leases — no asset tracking, no depreciation schedule, no residual-value accounting.
• Maintenance and replacement included. Some equipment leases bundle in maintenance, service contracts, and end-of-life replacement. If those costs are significant and unpredictable, bundling them into a fixed payment has real value that does not show up in a pure financing comparison.

The questions to ask before you decide

Before running any numbers, four questions cut through most lease-vs-buy decisions quickly:

1. How long will I actually use this equipment? If your honest answer is "through the useful life and beyond," buying almost always wins on total cost. If your answer is "until something better comes along," reconsider.
2. Do I have taxable income to absorb a large deduction? The 2026 Section 179 limit is $2,560,000 (per IRS Rev. Proc. 2025-32), but you can only use it up to your business taxable income for the year. If your income is low, the buying tax advantage shrinks considerably.
3. What is my real cost of capital? If you have other uses for cash that return 15% or more, tying it up in equipment ownership has an opportunity cost that a lease avoids. Conversely, if you have idle cash, the financing cost of a lease is pure expense.
4. What happens at end of term? With a lease, you return the equipment. With a loan, you own something with residual value. Model both endpoints honestly — the end-of-term value difference is often what settles close comparisons.
