The Most Expensive Contract in Your Business Might Not Be Your Loan - It Could Be Your Lease
Business owners often negotiate hard over the interest rate on a vehicle or equipment loan. Yet the lease on their premises can commit the business to hundreds of thousands - sometimes millions - of dollars over its life, with far less financial modelling.
Treasury is currently consulting with states and territories on whether retail tenancy rules should be made more consistent across Australia. That consultation is important for multi-state businesses, but the broader lesson is evergreen: a lease is not just a property document. It is a long-term cash-flow decision.

Base rent is only the beginning
The number quoted on the first page rarely captures the full commercial commitment. Owners need to model annual rent increases, outgoings, fit-out costs, legal fees, incentives, bank guarantees, maintenance obligations, make-good requirements and the cost of relocating if the premises no longer suit the business.
A rent-free period can improve early cash flow without making an uneconomic location economic. Likewise, a generous fit-out incentive can still sit inside a lease whose future rent grows faster than the business's margin.
Work backwards from the gross profit the site must create
The best test is not simply 'Can we afford the rent today?' It is 'How much additional gross profit must this location generate every month to cover the full occupancy cost?'
If the total occupancy cost is $180,000 a year and the business earns a 40% gross margin, the location needs $450,000 of additional sales merely to generate $180,000 of gross profit before other extra labour and operating costs. That calculation changes the conversation quickly.
Annual increases compound
A fixed 4% annual increase can look small in year one. Over a long lease, it compounds. A business should compare that rent trajectory with realistic sales and margin growth, not with optimism.
Think about exit before entry
Before signing, understand assignment rights, options, guarantees, make-good obligations and what happens if the business is sold. A lease can affect business value because a buyer inherits the economics of the site, not just the customer list.
The national reform discussion is useful - but it does not replace due diligence
Greater consistency in retail leasing could reduce complexity for businesses operating across jurisdictions. It will not make every lease a good commercial deal. Legal review and financial modelling remain separate jobs, and both matter.

FAQs / People Also Ask
What costs should I include when modelling a commercial lease?
Base rent, rent reviews, outgoings, fit-out, incentives, bank guarantees, maintenance, insurance and make-good obligations should all be considered.
Does a rent-free period make a lease cheaper?
It reduces cost for the incentive period, but the whole lease should be modelled over its full term.
Are retail lease laws the same across Australia?
No. State and territory regimes differ. Treasury is consulting on areas where greater consistency may be useful.
Before signing a commercial lease, make sure you understand the full financial commitment. Reviewing occupancy costs, rent increases and exit obligations can help protect cash flow and support sustainable growth.
