The most common reason Australian small businesses fail is not bad product, bad marketing, or bad management. It is rent they could not afford from day one. Understanding commercial rent affordability before you sign a lease is not optional — it is the foundational act of business planning.

The rent-to-revenue ratio: the only number that matters
Commercial rent affordability is not about how much rent you pay in absolute terms — it is about what percentage of your revenue goes to rent. A $3,000/month rent is crippling for a business turning over $15,000/month and comfortable for one turning over $50,000/month.
The industry benchmark for Australian retail and hospitality businesses is 8–12% of gross revenue. Above 12% requires exceptional margins to remain viable. Above 15% is statistically dangerous. Above 20% is where businesses typically fail within 24 months regardless of other factors.
How to calculate your maximum affordable rent
Maximum rent calculation
- 1
Estimate your conservative monthly revenue (use foot traffic × realistic capture rate × average transaction)
- 2
Multiply by 0.10 to get your 10% rent target
- 3
Multiply by 0.12 to get your absolute maximum at 12%
- 4
Any lease with rent above this maximum should be rejected or renegotiated
- 5
Build in a 6-month ramp-up period where revenue may be 40–60% of target
Worked example: café in inner Melbourne
Daily foot traffic past site: 120/hour peak Estimated capture rate: 3% Transactions per hour: 3.6 → 25/day (7hr trading) Average transaction: $9.50 Daily revenue: $237.50 Monthly revenue (26 days): $6,175 10% rent target: $617/month 12% absolute max: $741/month If the asking rent is $3,500/month — this site will fail.

Lease structure matters as much as the rent figure
The headline rent figure is only part of the affordability equation. Outgoings, fit-out contribution from the landlord, rent-free periods, and annual escalation clauses all affect the true cost of a lease over its term.
True cost of lease checklist
Base rent + estimated outgoings = gross occupancy cost Rent-free period: reduces effective annual cost Landlord fit-out contribution: reduces capital requirement Annual rent increase: CPI is acceptable, fixed % above 3% is not Personal guarantee: limit to 6–12 months where possible Break clause: negotiate a 12-month break option at year 2 or 3
FAQ: commercial rent in Australia
What is a good rent-to-revenue ratio for a café in Australia?
Eight to twelve percent is the healthy target range. Many successful independent cafés in Sydney and Melbourne operate between 9–11%. Below 8% is excellent. Above 13–14% requires careful margin management and is not sustainable long-term for most operators.
Can I negotiate commercial rent in Australia?
Yes, and you should. Particularly in the current market, landlords often have more flexibility than they initially indicate. Rent-free periods, fit-out contributions, capped annual increases, and break clauses are all negotiable.
What happens if my business cannot pay rent?
In Australia, commercial leases typically allow landlords to issue a breach notice after 14 days of missed rent. If not remedied, they may re-enter the premises and pursue the tenant for remaining lease obligations. Personal guarantees mean this liability can follow you personally.
