Every growing business eventually faces the same question: should we lease this equipment or buy it? The monthly payment on a lease almost always looks smaller than a loan payment or a cash purchase, which makes leasing feel cheaper. But the monthly payment is only one piece of a larger calculation that includes taxes, maintenance, resale value, and what your cash could earn elsewhere.
A full cost analysis compares the total cost of ownership under each path, adjusted for the time value of money and tax effects. This guide walks through every cost component, works through a realistic example, and shows you how to build the comparison for your own decisions.
Why the Monthly Payment Misleads
The lease quotes lead with the monthly payment because it is the most attractive number. A 100,000 dollar machine might lease for 1,900 dollars a month while a five year loan costs 2,100 dollars. The lease looks cheaper by 200 dollars a month. But that comparison ignores the ending: the loan borrower owns a machine, while the lessee owns nothing unless a buyout is paid.
The cash purchase looks worst on a monthly basis, because the entire 100,000 dollars leaves the business on day one. Yet for a profitable company that can use the tax deductions, cash can be the cheapest option of all. The monthly payment tells you about cash flow timing, not total cost. Confusing the two is the most common mistake in equipment decisions.
The Cost Components to Compare
A complete analysis has six components. First is the acquisition cost: the purchase price, plus delivery, installation, and training. Leases and loans both finance these, but fees differ. Lease origination fees, documentation fees, and security deposits add up, just like loan origination fees.
Second is the financing cost. For a loan, this is the interest paid over the term. For a lease, it is embedded in the payments as the lessor’s yield, which you can approximate from the money factor or implicit rate in the quote. Always ask the lessor for the implicit rate so you can compare it directly against loan offers.
Third is maintenance and operating cost. The user pays to maintain the equipment under either structure, but leases add return condition standards. A lessee returning equipment must meet the contract’s condition requirements, and refurbishment is a real end-of-term cost. Buyers face no such obligation, though they bear the full cost of major repairs after warranties expire.
Tax effects change the ranking
Fourth is the tax effect, which frequently decides the outcome. A buyer deducts depreciation, potentially including a large first-year Section 179 deduction. A lessee deducts lease payments. The present value of these deductions differs and scales with the company’s tax rate. A business in a high tax bracket gets more value from deductions than a startup with no taxable income.
Fifth is the residual or salvage value. A buyer keeps whatever the equipment is worth at the end of the analysis period. A lessee in a fair market value lease must pay market price to keep it, or walk away with nothing. Estimate residual value honestly: equipment that holds value favors buying, while equipment that depreciates fast favors leasing. The lease versus buy tax comparison for vehicles shows how residual assumptions swing the result.
Opportunity cost of cash
Sixth is the opportunity cost of cash. Money spent on a cash purchase cannot be used elsewhere. If the company can earn 12 percent deploying cash into inventory or expansion, tying up 100,000 dollars in equipment has a real cost. Leasing and loans both preserve cash, and that preservation belongs in the analysis.
Analysts handle this by discounting all cash flows to present value at the company’s cost of capital. This single step accounts for timing automatically: a dollar paid today counts more than a dollar paid in year five. If you do nothing else, discounting the cash flows will dramatically improve your comparison.
A Worked Example: 100,000 Dollar Machine
Consider a manufacturer choosing between three paths for a 100,000 dollar packaging machine with a seven year useful life. The analysis period is five years, the cost of capital is 10 percent, the marginal tax rate is 25 percent, and the machine will be worth 20,000 dollars after five years.
Option A is a cash purchase: 100,000 dollars on day one, a Section 179 deduction saving 25,000 dollars in year-one taxes, and a machine worth 20,000 dollars at the end of year five. Discounted at 10 percent, the present value of total cost is roughly 62,600 dollars.
Option B is a five year loan at 8 percent with 10 percent down: 10,000 dollars upfront and about 1,825 dollars a month, with depreciation and interest deductions. After five years the company owns a machine worth 20,000 dollars. Present value of total cost: roughly 66,000 dollars, slightly worse than cash due to interest and delayed tax benefits.
Option C is a five year fair market value lease at 1,900 dollars a month with nothing down. Deductible payments save 475 dollars a month in taxes. Total payments are 114,000 dollars, tax savings 28,500 dollars, and the company owns nothing at the end. Present value: roughly 68,700 dollars, the highest of the three, since the lessee pays the lessor’s profit and keeps no residual.
This example favors buying, but the ranking flips with different assumptions. A four year useful life, a 5,000 dollar residual, and no taxable income make the lease win comfortably. The numbers are illustrative, but the method is the point: spell out the assumptions, discount the cash flows, and let the math speak. Vehicle buyers can apply the same framework, since leasing versus buying an electric car turns on the same residual and tax questions.
When Buying Wins the Analysis
Buying, with cash or a loan, usually wins when the equipment has a long useful life and holds its value: manufacturing machinery, material handling equipment, and well-maintained heavy equipment. The buyer captures the residual value and eventually operates the equipment payment-free, which no lease can match.
Buying also wins for profitable companies in high tax brackets that can fully use depreciation deductions. The combination of Section 179 and a valuable residual is powerful. Buying also wins when the equipment will be customized, since modifications to leased equipment are restricted and must often be reversed at return.
Cash purchases specifically win when the company has excess cash earning low returns. If idle cash earns 4 percent while equipment loans cost 8 percent, deploying the cash avoids the interest spread. Still discount at the cost of capital, not at zero, to keep the comparison honest.
When Leasing Wins the Analysis
Leasing usually wins for equipment with short technology cycles: computers, medical imaging devices, and telecom gear. The lease transfers depreciation risk to the lessor. The lessee pays for the useful portion and walks away before obsolescence bites.
Leasing also wins when preserving cash matters more than minimizing total cost. A growing business earning 20 percent on working capital should not tie up cash in equipment to save a few thousand in financing costs. The return on deployed cash dwarfs the financing spread.
Leasing also wins for companies with little or no taxable income. Depreciation deductions are worthless to a company paying no taxes, while the lease’s lower payments help immediately. Startups often lease for exactly this reason. A dollar buyout lease can split the difference, offering lease-like payments with an ownership-style ending, though it is taxed as a purchase.
Building Your Own Comparison
Start by defining the analysis period: the shorter of the equipment’s expected useful life and your planning horizon. A seven year machine you will replace in four should be analyzed over four years, with the residual estimated at year four.
List every cash flow under each option: upfront payments, monthly payments, tax savings by year, maintenance differences, end-of-term costs, and terminal value. Be specific about tax timing, since a year-one deduction is worth more than the same deduction spread over five years.
Discount all cash flows at your company’s cost of capital. If you do not know it, use the rate on your business line of credit as a proxy. Then compare the present values. The lowest present value of cost is the economically best choice, before non-financial factors.
Finally, layer in qualitative factors: flexibility needs, balance sheet preferences, administrative burden, and technological change risk. A rigorous analysis gets you to the right neighborhood, and judgment gets you to the right address. For equipment with meaningful fuel or energy costs, fold those into the operating comparison too, since efficiency differences can outweigh financing differences, as hybrid versus gas cost comparisons regularly demonstrate.
Lease versus buy is not a philosophical question. It is an arithmetic question with assumptions you must make explicit. Run the numbers with honest residuals, real tax rates, and discounted cash flows, and the better path usually becomes clear. Revisit the analysis for each major acquisition, because last year’s answer may be wrong for this year’s equipment.
