Do You Actually Understand Your Commercial Lease Rent Structure?
- May 18
- 4 min read

A commercial lease rent structure is one of the largest fixed costs in your business, yet for many operators, it’s also one of the least understood. You signed the lease. You accepted the annual increases. And since then… you’ve probably just absorbed the cost.
But here’s the issue:
rent doesn’t just increase, it compounds, shifts, and quietly changes how much of your revenue it consumes.
If you haven’t reviewed how your rent actually works, there’s a good chance you’re paying more than you realise, or at the very least, not managing it strategically.
Why This Matters Now
Across Australia, commercial rent increase clauses are becoming more complex and more impactful.
Government guidance shows that lease agreements often include structured increases, review clauses, and additional obligations that many tenants don’t revisit after signing (see Business.gov.au’s guide to leasing business premises).
At the same time:
Turnover-based leases are more common in hospitality
Outgoings are rising (utilities, council rates, insurance)
CPI-linked increases are compounding faster than expected
This means your occupancy cost percentage may be increasing without clear visibility.
The Different Types of Rent Structures
(Most Operators Overlook)
1. Fixed Rent (Base Rent)
This is the simplest model:
A set dollar amount per month or year
Typically increases annually (CPI or fixed %)
The risk:It feels predictable, but over time, compounded increases can significantly outpace revenue growth.
2. CPI or Fixed Percentage Increases
Most leases include automatic increases such as:
CPI-linked adjustments
Fixed annual increases (e.g. 3–5%)
Australian tenancy resources outline how these increases are commonly applied across lease terms (outlined in the WA Commercial Tenancy Guide).
What to watch:
CPI spikes can accelerate rent unexpectedly
Fixed increases may exceed actual business growth
3. Percentage Rent (Turnover Rent)
Common in hospitality and retail:
Base rent + a percentage of revenue above a threshold
Example:
7% of turnover once revenue exceeds $1M
This model, often called a percentage lease, allows landlords to share in business performance (explained in Investopedia’s percentage lease overview).
Why operators underestimate it:
It’s rarely modelled properly before signing
Growth can trigger disproportionately high rent costs
4. Outgoings (The Hidden Layer)
This is where leases become less transparent.
Outgoings can include:
Council rates
Insurance
Maintenance
Cleaning and common area costs
Legal guidance highlights that these costs are often passed through to tenants and can vary significantly year to year (see LegalVision’s explanation of commercial lease outgoings).
Key issue:Outgoings are variable and often increase faster than rent itself.
What Is a Healthy Occupancy Cost?
For most hospitality businesses:
8–12% of revenue → Healthy range
12–15% → Pressure building
15%+ → Often unsustainable
Industry benchmarks consistently show occupancy as a critical metric alongside food and labour (see Eat’s top metrics to follow).
If your lease includes turnover rent and rising outgoings, this percentage can increase quickly, even if base rent appears stable.
Why Your Rent Keeps Rising
(Even If Nothing Changes)
Rent increases rarely come from a single source.
They typically combine:
Annual CPI or fixed increases
Turnover rent triggering at higher revenue
Rising outgoings
Periodic market reviews
State-based tenancy resources outline how these mechanisms operate within lease agreements. Individually, each increase seems manageable.Together, they quietly erode margin.
The Real Risk: Not Reviewing the Structure
Most operators:
Track labour weekly
Monitor food costs closely
Review suppliers regularly
But rent?
It often goes untouched for years.
The issue isn’t just cost, it’s a lack of visibility into:
What’s driving increases
How future costs will evolve
Whether the structure still suits the business
What Operators Should Do
1. Break Down Your Rent Structure
Understand:
Base rent
Increase mechanism
Turnover clauses
Outgoings
If you can’t clearly explain it, you don’t fully understand it.
2. Calculate Your True Occupancy Cost
Include:
Base rent
Turnover rent
All outgoings
Then express it as a percentage of revenue.
3. Model Future Increases
Project:
3–5 years of rent
Impact of CPI or fixed increases
Growth scenarios under turnover rent
4. Review Before Renewal
Your best opportunity to renegotiate is:
Before exercising lease options
Before renewal periods
5. Benchmark Against Industry
Compare your occupancy cost to:
Industry benchmarks
Similar venues
Your own historical performance
This turns rent from a passive cost into an actively managed one.
The Bigger Insight
Rent is rarely the most dramatic expense.
But it is one of the most consistent, increasing quietly, predictably, and often without review.
Over time, that consistency has a compounding impact on profit.
Conclusion
You agreed to your lease based on what made sense at the time. But your business has changed.Your revenue has changed.Your cost structure has changed.
The question is:
Do you still understand your rent, or are you just absorbing it?
CTA: Understand What You’re Really Paying
Rent is often one of the largest fixed costs in a business, yet many owners haven’t reviewed their lease structure since signing.
Small details in rent increases, outgoings, and terms can have a long-term impact on profit.
The first step is understanding how your rent actually works.
