Operating Lease vs Buying | When Leasing Makes More Sense

The Core Difference

When you buy an asset (using cash or a chattel mortgage), you own it. You get the depreciation, the equity — and the risk that it loses value. When you take an operating lease, you rent the asset for a fixed period and return it at the end. The lessor carries the residual value risk.

The right choice depends on how you use the asset, how quickly it becomes obsolete, and whether cash flow or equity matters more to your business.

Side-by-Side Comparison

Factor	Buying (Chattel Mortgage)	Operating Lease
Ownership	You own from settlement	Lessor owns; you return at end
Balance sheet	Asset + liability on books	Expense only (pre-AASB 16)
Monthly cost	Higher (full asset value)	Lower (only usage cost)
GST	Full upfront credit	Claimed on each payment
Tax deduction	Depreciation + interest	Entire lease payment
Residual risk	You bear it	Lessor bears it
Flexibility	Locked in; sell to exit	Return at end; upgrade easily
End of term	You own a depreciating asset	Walk away or lease new

When an Operating Lease Wins

Technology assets — vehicles and equipment that become obsolete quickly (e.g., Euro 6 truck engines replacing Euro 5)
Project-based work — you need the asset for a specific contract, not forever
Cash flow priority — lower monthly payments preserve working capital
Fleet rotation — companies that replace vehicles every 3–5 years anyway save on disposal costs
Maintenance bundling — some operating leases include servicing, making total cost predictable
Balance sheet management — keeping assets off the balance sheet (where applicable) improves financial ratios

When Buying Wins

Long-term use — if you'll keep the asset for 10+ years, owning avoids paying perpetual rental fees
Strong residual value — assets like well-maintained trucks hold value; ownership lets you capture that equity
Instant Asset Write-Off — immediate deduction of the full purchase price under current ATO incentives
Customisation — heavy modifications are easier when you own the asset (lessors may restrict modifications)
Emotional/strategic preference — many owner-drivers prefer to build equity in their fleet

Total Cost Example

$150,000 Truck Over 5 Years

Chattel Mortgage (6.9%, 30% balloon):
Monthly repayments: ~$2,225
Total paid over 5 years: ~$133,500 + $45,000 balloon = $178,500
Asset value at end: ~$60,000–$80,000
Net cost after resale: ~$98,500–$118,500

Operating Lease (same truck):
Monthly lease: ~$2,800 (includes maintenance)
Total paid over 5 years: ~$168,000
Asset value at end: $0 (returned)
Net cost: $168,000

In this example, buying is cheaper if the truck resells for $60K+ — but the operating lease eliminates resale risk and maintenance headaches.

AASB 16 & Balance Sheet Impact

Since 2019, AASB 16 requires most leases (including operating leases) to be recognised on the balance sheet for reporting entities. This means the traditional "off-balance-sheet" advantage of operating leases has diminished for companies that report under Australian Accounting Standards.

However, for small businesses using simplified reporting, operating leases may still be treated as expenses without balance sheet recognition. Check with your accountant whether AASB 16 applies to your business.

Frequently Asked Questions

Some operating leases offer a purchase option at end of term, but it's not guaranteed. If buying at end is important, a finance lease (which always includes a purchase option) may be more suitable.

It depends. Under chattel mortgage, you claim depreciation plus interest. Under operating lease, the entire lease payment is deductible. If the Instant Asset Write-Off applies, buying can provide a massive Year 1 deduction. Use our calculator to model both scenarios.

You're responsible for maintaining the asset in good condition. At return, the lessor will assess wear and tear. Excess damage results in an end-of-lease charge. Comprehensive insurance covers major damage, but cosmetic wear may still incur fees.
