Lease vs Buy Comparison
The choice between leasing and buying depends on three factors: upfront cash, total cost, and ownership needs. Leasing requires minimal upfront cash, usually just the first month's payment. Buying requires a down payment plus closing costs. If cash is tight, leasing looks attractive. But over a 5-year period, leasing often costs 30-50% more than buying.
The tax implications differ significantly. Lease payments are fully deductible as an expense. For purchased equipment, you deduct depreciation over several years plus interest on any loan. This deduction is worth 20-30% of the purchase cost depending on your tax bracket. High-tax businesses benefit more from the deduction. If you have limited taxable income, the deduction is worth less.
Equipment resale value also matters. Equipment holding value (vehicles, tools, machinery) favors buying. Equipment becoming obsolete quickly (computers, software licenses) favors leasing because you avoid residual value risk.
How the Equipment Lease Calculator Works
Enter the equipment price, expected lease payment, interest rate on a purchase loan, your tax bracket, and expected resale value after your use period. The calculator computes total costs for both options including tax benefits and residual value, then shows which option costs less and how much you'll save.
The calculator accounts for the timing of tax deductions. If you lease, 100% of payments are deductible immediately. If you buy, depreciation deductions spread across 5-7 years reduce your taxable income gradually. The calculator applies your tax bracket to these deductions so you see the after-tax cost.
The Mathematics of Each Option
For a $100,000 equipment purchase over 5 years, the calculation starts with total payments: loan down payment plus 60 monthly payments. If you're financing $80,000 at 6% interest, your monthly payment is approximately $1,540, resulting in total payments of $92,400. With tax benefits from depreciation and interest deductions worth $33,960 at a 30% tax rate, your net cost to buy is roughly $49,240.
Leasing the same equipment at $2,100 per month costs $126,000 over 60 months. The tax deduction for those payments at 30% saves $37,800. But you have no residual value and no equipment at the end. Your net cost to lease is approximately $88,200.
The $38,960 difference means buying costs significantly less over 5 years if you can afford the upfront cash and the equipment retains value. But if $20,000 down payment would strain your working capital, the extra $38,960 cost might be worth preserving liquidity.
When to Lease
Lease when cash is very tight, technology changes quickly, equipment becomes obsolete, you only need it short-term, or you can't afford a down payment without hurting operations. Software, computers, and office equipment are good candidates for leasing because they become obsolete in 3-5 years. Medical equipment and specialized tools often lease well because technology improves quickly.
Leasing also transfers maintenance risk to the lessor. The lease payment includes repairs and replacements. If a machine breaks, the lessor fixes it. This certainty is valuable if you can't afford downtime or major repairs. Businesses with no technical expertise also benefit from leasing because the lessor handles all maintenance.
When to Buy
Buy when you have solid cash flow, equipment holds resale value, you'll use it 5+ years, you have sufficient working capital to absorb the down payment, and the tax deduction helps your situation. Vehicles, manufacturing equipment, real estate, and tools are good buy candidates because they hold value.
Buying also provides flexibility. You control maintenance and repairs, can modify or upgrade equipment as needed, and keep residual value. If you build equity over 5 years and resell for $30,000, that reduces your effective cost.
High-tax-bracket businesses benefit more from deductions. A 30% tax bracket turns a $3,000 interest deduction into $900 in tax savings. A 21% tax bracket turns it into $630. If you're in a low-tax situation, leasing might cost less after tax effects.
How to Use
Enter Equipment Cost. Put the purchase price or fair market value of the equipment.
Enter Lease Payment. Put the monthly lease payment you're being quoted, or estimate from similar equipment.
Set Interest Rate. For a purchase loan, enter the rate you'd pay (typically 5-8% for business loans).
Enter Loan Term. Usually 3-5 years for equipment financing.
Enter Tax Bracket. Your combined federal and state income tax bracket (typically 25-37% for business owners).
Enter Resale Value. Estimate what the equipment will be worth when you're done with it. For vehicles, research blue book value after 5 years. For machinery, estimate 20-40% of original cost.
Try this: $100,000 equipment, $2,100 monthly lease, 6% purchase interest, 5-year term, 30% tax bracket, $30,000 resale value. The calculator shows buying costs $49,240 net versus leasing at $88,200, a $38,960 difference favoring purchase.
Common Mistakes
Ignoring tax deductions. The deduction is real money. Don't skip it when comparing options.
Overestimating resale value. Be conservative. Equipment doesn't hold value as well as you hope. If you guess $30,000 resale but get $15,000, buying cost much more.
Underestimating maintenance costs. Ownership requires upkeep. Budget repairs and maintenance into the buy cost, or lease to avoid these surprises.
Using a purchase-only perspective. Leasing preserves cash and avoids obsolescence risk. These matter even if leasing costs more on paper.
Forgetting disposal costs. Selling used equipment costs money: transport, auction fees, or just time finding a buyer. Factor this into resale value estimates.
Advanced Tips
Negotiate lease terms aggressively. The first quote isn't final. Ask for lower monthly payments or shorter terms, especially for longer contracts.
Compare multiple lease and purchase offers. Banks and lease companies offer different rates. Get at least 3 quotes before deciding.
Model downside scenarios. What if you use equipment for 3 years instead of 5? What if it's worth 10% less? Sensitivity analysis reveals which option wins under different conditions.
Use business-expense-calculator to model the impact of equipment cost on profit margins. Large equipment purchases can strain profitability temporarily.
Consider sustainability in the decision. If you'll upgrade or replace in 2-3 years, leasing is probably better. If you'll use for 10 years, buying is almost always better.
Once you've decided whether to lease or buy, calculate impact on cash flow. Use the business-cash-flow-calculator to project monthly cash position under the lease or purchase scenario. If purchasing would drain working capital below your safety threshold, leasing might be wiser even if it costs more long-term. The business-line-of-credit-calculator helps you see whether a line of credit could cover cash shortfalls from an equipment purchase.
