Lease Versus Buy: The Math Your Equipment Rep Won't Show You
Your compressor is dying. New one costs $8K out of pocket. Lease is $180/month, 60-month term. That's $10.8K total. Seems worse, right? you're wrong.
Buy: $8K cash now. Resale value in 5 years: $1.2K. Repairs year 2-5: average $400/year. Net cost: $7.8K. Plus opportunity cost on the $8K if you need that cash for marketing or hiring.
Lease: $10.8K over five years. Warranty included. Replacement covered if it fails. Upgrade option at lease end. Technology risk: none. Your cash flow: minimal impact.
The math shifts if you're borrowing at 8% interest. Buy at $8K becomes $8K plus $1,200 in interest. Now lease looks smart. The math also shifts if you plan to keep the practice 20 years. Then buy makes sense.
Real talk: most practices should lease high-depreciation equipment (compressors, suction, small instruments) and buy high-duration equipment (chairs, lights, X-ray units). But you have to know your cash position first.
Lease agreements vary wildly. Some lock you in at 6% escalation. Others offer buyout at 40% of remaining balance. Read the fine print. The equipment rep is paid on gross margin, not your efficiency.
The decision isn't buy or lease. It's: do you have cash flow for capex, or not?
OPERATOR MATH (illustrative model — adjust inputs to your practice data)
Let's compare the true 5-year cost of leasing versus buying a $8,000 compressor with realistic assumptions.
Scenario 1: Buy with cash.
Purchase price: $8,000 (paid upfront).
Resale value after 5 years: $1,200 (15% residual).
Maintenance/repairs (years 2-5): $400/year × 4 years = $1,600.
Total 5-year cost: $8,000 - $1,200 + $1,600 = $8,400.
Opportunity cost of capital: $8,000 invested at 6% annual return = $8,000 × (1.06^5 - 1) = $2,764 in foregone investment gains.
Adjusted total cost including opportunity cost: $8,400 + $2,764 = $11,164.
Scenario 2: Buy with financing (8% interest, 5-year term).
Loan amount: $8,000.
Monthly payment: $162 (60 months at 8% APR).
Total payments over 5 years: $162 × 60 = $9,720.
Interest paid: $9,720 - $8,000 = $1,720.
Resale value: $1,200.
Maintenance: $1,600.
Total 5-year cost: $9,720 - $1,200 + $1,600 = $10,120.
Scenario 3: Lease ($180/month, 60-month term).
Total lease payments: $180 × 60 = $10,800.
Maintenance/repairs: $0 (included in lease warranty).
End-of-lease buyout option: $1,200 (15% of original cost).
If you choose not to buy out: Total cost = $10,800.
If you buy out at lease end: $10,800 + $1,200 = $12,000 total cost.
Cost comparison summary:
Buy with cash (including opportunity cost): $11,164.
Buy with financing (8% interest): $10,120.
Lease (no buyout): $10,800.
Lease (with buyout): $12,000.
Winner: Buy with financing at $10,120 total cost.
But wait - this assumes you have borrowing capacity and 8% financing available. If your credit is constrained or you're already used, leasing may be your only option.
Cash flow comparison:
Buy with cash: $8,000 upfront hit to cash reserves. If you have $50,000 in operating cash and an unexpected $12,000 HVAC repair hits in month 2, you're now at $30,000 cash reserves (uncomfortable).
Lease: $180/month. Predictable. Your $50,000 cash reserve stays intact for emergencies.
The lease "costs" you an extra $680 over 5 years ($10,800 lease vs. $10,120 financed purchase), but you preserve $8,000 in liquidity. That liquidity is worth far more than $680 if you need it for payroll, marketing, or emergency repairs.
Tax implications (bonus depreciation):
If you buy the compressor, you can deduct 100% of the cost in Year 1 under Section 179 or bonus depreciation (assumes current tax law).
Tax benefit: $8,000 × 25% marginal tax rate = $2,000 tax savings in Year 1.
If you lease, you can only deduct lease payments annually: $2,160/year × 25% = $540/year in tax savings ($2,700 total over 5 years).
Buying generates $2,000 in Year 1 tax savings. Leasing generates $2,700 spread over 5 years. Present value of lease tax benefit (discounted at 6%): $2,700 ÷ (1.06^2.5 average time) ≈ $2,400.
Net tax advantage: Buying wins by $200 in present value terms (negligible).
Breakeven analysis:
Leasing makes sense if:
• You have less than $15,000 in cash reserves (preserve liquidity)
• Your borrowing cost exceeds 10% (lease is cheaper than high-interest debt)
• Equipment has high failure risk (lease warranty saves $1,000-$2,000 in repairs)
• You plan to upgrade in 3-5 years (lease includes upgrade options)
Buying makes sense if:
• You have $30,000+ in cash reserves (liquidity not a concern)
• You can borrow at <8% (financing beats lease cost)
• You plan to keep the equipment 7-10 years (buyout cost amortizes over longer period)
• Equipment has low failure rates (compressors, chairs, lights)
THE TAKEAWAY
Action items:
1. Know your cash position before deciding. Pull your last 3 months of cash flow statements. If your average cash balance is below $20,000, lease high-depreciation equipment to preserve liquidity. If you have $40,000+ in reserves, buy with financing (if rates are <8%).
2. Separate high-depreciation from low-depreciation equipment. Lease: compressors, suction units, digital sensors (fail frequently, upgrade cycles <7 years). Buy: chairs, operatory lights, X-ray units (last 10-15 years, low failure rates).
3. Negotiate lease terms aggressively. Ask for: (a) $0 buyout at lease end, (b) warranty coverage for all repairs, (c) no annual escalation clauses, (d) early termination option with 50% remaining balance buyout. Most reps have 10-15% margin to negotiate.
4. Compare total 5-year cost, not monthly payments. A $150/month lease sounds cheap, but $9,000 total cost over 5 years may exceed the $7,500 financed purchase cost. Run the full amortization table before signing.
5. Factor in tax benefits. If you're buying, accelerate the deduction in Year 1 using Section 179. If leasing, spread the deduction over 5 years. Consult your CPA to model the cash flow impact. A $2,000 Year 1 tax refund can fund a marketing campaign or staff bonus.
Equipment reps sell on monthly payments, not total cost. You decide based on cash flow, liquidity, and total cost of ownership. Do the math yourself.
