The lease salesperson has a compelling pitch. Low monthly payments. No large upfront outlay. Latest model every 3 years. Hand it back when you're done.
The purchase case is equally compelling. You own the asset. No ongoing payments after payoff. Residual value at end of life.
Both arguments sound reasonable. Neither tells you which option actually costs less. That requires a TCO analysis — and the answer is rarely obvious.
Why This Decision Is Harder Than It Looks
Leasing and buying have different cost structures that make direct comparison difficult.
Leasing front-loads convenience and spreads cost over time. Buying front-loads cost and recovers some of it through residual value. To compare them properly, you need to put everything on the same timeline and in the same currency.
The variables that matter most are ones neither party volunteers upfront: maintenance responsibilities, end-of-lease fees, residual value assumptions, and what happens when the asset breaks.
The right question isn't "is leasing cheaper than buying?" It's "what does each option cost over the period I plan to use this asset?" That's a TCO question, not a monthly payment question.
The Lease vs Buy Framework
Step 1: Set the time horizon
How long do you plan to use this asset? This is the most important variable.
If you plan to use equipment for 2 years, a short lease may well be cheaper than purchasing. If you plan to use it for 7+ years, purchasing almost always wins. The crossover point — where buying becomes cheaper than leasing — is typically between years 3 and 5 for most equipment categories.
Step 2: Calculate total lease cost
Don't stop at monthly payments. The true cost of leasing includes:
| Lease cost component | Notes |
|---|---|
| Monthly payments × term | The headline number |
| Upfront deposit or advance payments | Often 1–3 months |
| Maintenance and tyres (if not included) | Check the fine print |
| Insurance (if not included) | |
| End-of-lease fees | Excess kilometres, damage, admin |
| Early termination penalties | If there's any chance you exit early |
| Total lease cost |
Step 3: Calculate total purchase cost
| Purchase cost component | Notes |
|---|---|
| Purchase price (or loan total cost) | Include all interest if financing |
| Registration and stamp duty | |
| Insurance (typically higher for owned assets) | |
| Maintenance over the period | Increases with age |
| Repairs (estimate based on asset type) | |
| Less: residual value at end of period | What you sell it for |
| Total purchase cost |
Step 4: Add hidden costs to both
Both options have hidden costs that don't appear in the contract:
Admin overhead — Fleet management, lease administration, registration renewals, service bookings. For a 10-vehicle fleet, this can be 5–10 hours per month of internal labour.
Downtime cost — When equipment fails, what does it cost? For a delivery vehicle: lost revenue per day. For a printer: IT time + productivity loss for affected staff.
Flexibility cost — Locked into a 3-year lease when your needs change? The penalty for exiting early can be substantial.
A Worked Example: Fleet Vehicle
A business needs a fleet vehicle for 4 years. Here's the comparison:
| Lease (4yr) | Purchase (4yr) | |
|---|---|---|
| Monthly payment × 48 | $36,000 | — |
| Purchase price | — | $55,000 |
| Loan interest (5yr at 6.5%) | — | $9,200 |
| Maintenance (lease included) | $0 | $8,000 |
| Insurance premium difference | $0 | $2,400 |
| End-of-lease fees (est.) | $2,500 | — |
| Residual value | $0 | -$18,000 |
| Total 4-year cost | $38,500 | $56,600 |
In this scenario, leasing is significantly cheaper over 4 years. But change two variables — use the vehicle for 7 years instead of 4, or increase the residual value assumption — and the result flips.
When Leasing Wins
- Short to medium usage period (under 4 years)
- You need the latest model or technology regularly
- Capital preservation matters — you'd rather keep cash in the business
- The lessor includes maintenance, reducing admin burden
- Tax treatment favours lease payments as operating expenses
When Buying Wins
- Long usage period (5+ years)
- The asset holds its value well (certain vehicle categories, specialist equipment)
- You'll customise or modify the asset (not permitted under most leases)
- Volume and scale — buying outright for a large fleet often attracts better pricing
- You want certainty — no end-of-lease surprises
Watch for residual value assumptions in lease contracts. Lessors sometimes set artificially low residual values to reduce headline monthly payments — this means you're paying down more of the asset cost through lease payments than you realise. A lower residual = higher total lease cost.
The Lease vs Buy Decision for Technology Equipment
Computers, servers, printers, and AV equipment have some specific characteristics that change the analysis:
Depreciation is fast. A laptop worth $2,500 today may be worth $400 in 3 years. This makes residual value assumptions critical — and often favours leasing for technology.
Refresh cycles matter. If your business needs current-generation hardware, leasing lets you refresh without disposing of owned assets. Buying and selling 3-year-old laptops at scale is more complex than it appears.
Maintenance risk is real. Out-of-warranty repairs on owned hardware can be significant. A managed lease with included support reduces this risk.
For most businesses, technology equipment leasing makes sense for assets with a 3-year replacement cycle. Purchasing makes sense for assets used beyond 5 years or heavily customised setups.
Running Your Own Analysis
The lease vs buy decision has too many variables for a back-of-envelope calculation. You need to model the full cost of each option on the same timeline — including residual values, maintenance escalation, and admin overhead.
