Understanding Ratchet Clauses in Australian Business Agreements

When you’re running or growing a business, negotiating contracts can feel overwhelming - there are so many moving parts to consider, from prices and payment terms to what happens if things go wrong. One concept that catches many Australian business owners by surprise is the ratchet clause. While it might sound technical, understanding how these clauses work, and what impact they can have, is key to protecting your interests and making sound decisions in leases, financing, equity deals, and more. Ratchet clauses can help manage risk, but they can also lock you into less flexible or more expensive terms if you’re not careful. In this guide, we’ll break down exactly what a ratchet clause is, look at real-world examples (including ratchet clauses in leases), and provide practical guidance to help you approach your next contract negotiation or business expansion with confidence. If you’ve ever wondered “what is a ratchet clause?” or whether you should agree to one in your business agreement, read on - we’ll cover what you need to know and give you the right questions to ask before signing on the dotted line.

What Is a Ratchet Clause?

A ratchet clause is a type of contract term that sets a floor or cap on how much a particular amount - usually a price, rent, or value - can increase or decrease over time. The “ratchet” mechanism ensures that certain figures in your agreement can only move in one direction, or that any decreases are limited compared to increases. In plain English, a ratchet clause stops you from “going backwards” on price, rent, profit shares, or other important numbers. For example, if your rent can only ever go up - or stays the same - but never drops, you’re probably dealing with a ratchet clause. These clauses are common in leases, equity and investment agreements, and sometimes supply or loan arrangements. Whether they’re right for your business depends on how they’re drafted and whether their effects are balanced and fair.

How Do Ratchet Clauses Work? (With Examples)

Ratchet clauses can apply in different contexts. Here’s how you might see them in practice:
  • Rental Agreements (Commercial Leases): In a commercial lease, a ratchet clause often means that your rent will never fall below its previous year’s amount - even if market rent drops, or if a normal rent review (as set out in your lease terms) would have resulted in a reduction. For example, if the lease allows annual rent reviews and the new market rent is lower than what you’ve been paying, the ratchet clause ensures the rent stays the same or goes up - never down.
  • Equity or Investment Deals: In startup financing, a “ratchet” (sometimes called an “anti-dilution ratchet”) can protect investors by guaranteeing them extra shares if additional funding is raised at a lower price per share - ensuring their ownership percentage is not diluted too much.
  • Price Escalation Clauses: In supply contracts or long-term agreements, a ratchet clause might specify that prices can’t drop below a set minimum, protecting the seller from falling prices.
Let’s walk through a common ratchet clause example from the commercial leasing world: Example: You lease a shopfront for your business on a five-year lease. The contract says rent increases are tied to the Consumer Price Index (CPI), but also contains a ratchet clause: “The rent will not decrease below the previous year’s rent, even if the CPI calculation would have led to a lower rent.” This protects the landlord, but as a tenant, your rent can only go up, never down - even if the market shifts in your favour.

Types of Ratchet Clauses in Business Contracts

Depending on the agreement, you may come across different types of ratchet clauses. It’s important to know how each might affect your business:
  • Upward-Only Ratchet: This is the most common variety. It means the amount (such as rent or price) can only rise or remain the same - it can never drop. These are seen often in commercial leases in Australia.
  • Partial Ratchet (or “Cap and Collar”): This sets both an upper and lower limit for changes - so while the price can fall, it can’t drop more than a set percentage. But increases may not have a cap, or vice versa.
  • Full Ratchet (in Investment Law): In equity deals, this kind of ratchet lets investors adjust their shareholding if new shares are issued at a lower price - maintaining the value of their original investment.

Should I Agree to a Ratchet Clause?

Whether you should accept a ratchet clause depends on your position, the broader terms of your agreement, and your risk appetite.
  • Business Owners and Tenants: Ratchet clauses can be a red flag if you want flexibility and the ability to benefit from market downturns (for example, falling commercial rents). If the clause is “upward only”, you may face steadily rising costs even as your industry slows down.
  • Landlords or Investors: Ratchet clauses offer important security - they ensure predictable or growing income streams and can help manage uncertainty. These protections, however, may make your offer less attractive to sophisticated tenants or co-founders who are aware of the risks.
Our advice? Always read any ratchet clause carefully and consider the long-term potential impacts. Don’t hesitate to seek legal advice before signing - what seems like a small tweak in a dense contract now could have big financial consequences down the track.

Are Ratchet Clauses Enforceable in Australia?

In general, ratchet clauses are legal and enforceable in Australia - if you willingly agree to them in a contract. However, certain states and contract types (like retail shop leases) do have restrictions. For example, in NSW retail leases, “ratchet rent review clauses” that stop rent dropping below a base amount following market review are generally not allowed under the Retail Leases Act 1994 (NSW). For other types of business agreements, it’s up to the parties to negotiate the terms. If you’re presented with a contract containing unfamiliar ratchet provisions, or you’re unsure how they could affect your rights, it’s wise to get a contract review from a legal expert familiar with your industry.

Key Issues to Watch Out for with Ratchet Clauses

No matter which side of the agreement you’re on, here are some important things to consider when dealing with ratchet clauses:
  • Transparency: Make sure the clause is crystal clear about how and when it applies, and how increases (or limits on decreases) are calculated.
  • Negotiability: Just because a ratchet clause is in the draft doesn’t mean you can’t negotiate it. You might be able to agree to a partial ratchet or set a stricter cap on increases to offer some balance.
  • Long-term Impact: Model your financial forecasts both with and without the ratchet effect to understand best and worst case scenarios. Could rising rent or repayment costs put your business under strain in a downturn?
  • Statutory Compliance: Always check if there are state-based restrictions (like in NSW or Victoria for leases) that could override what you and the other party have agreed.
  • Other Contract Terms: Look at the ratchet provision in the context of the whole contract - what happens at renewal, break clauses, or if you want to assign (transfer) your lease or agreement?
If you ever feel overwhelmed, remember you’re not alone - getting the right legal advice early makes the process much smoother and means you can enter business relationships with your eyes open.

How Can I Negotiate a Fair Ratchet Clause?

If you’re being asked to agree to a ratchet clause, you have every right to push for a fairer version. Here are some practical tips to help you negotiate with confidence:
  • Ask for Clarity: Insist on a written clause that clearly explains how the ratchet operates - there should be no hidden triggers or “catch-all” language.
  • Propose Alternatives: If a full “upward only” ratchet is too restrictive, suggest a partial ratchet or a cap and collar arrangement, where decreases are limited but not totally blocked.
  • Check Rent Review Mechanisms: For leases, ask how rent is reviewed - CPI, market review, fixed percentage? Negotiate to ensure there is opportunity for a fair market adjustment, not just automatic increases indefinitely.
  • Review Renewal and Break Clauses: Make sure you’re not stuck with unfavourable ratchet terms for the entire life of the contract, especially on multi-year leases or long-term service agreements.
  • Get Professional Help: Speak with a lawyer who has experience with commercial contracts - they can spot risks you might miss and help draft balanced terms.
Ratchet clauses can appear in several common business agreements. Be especially on the lookout when reviewing: If you’re not sure what to look for, working with a commercial lawyer ensures you’re protected from hidden pitfalls and gives you the confidence to spot unfair terms before they cause trouble.

Next Steps: Protect Your Business from Unfair Contract Terms

Even if your contract already includes a ratchet clause, there are steps you can take to limit risk and maintain flexibility for your business:
  • Document Everything: Ensure every major agreement - especially long-term leases or investment deals - is fully documented and stored safely. Keeping clear records helps prove what was or wasn’t agreed later on.
  • Know Your Rights Under Australian Consumer and Small Business Laws: In some cases, certain unfair contract terms (including some ratchet clauses) could be voided under the Australian Consumer Law if they are excessively one-sided.
  • Review Agreements Regularly: Don’t just “set and forget” - even if the ratchet clause seemed fine at the start, changes in your situation or in the law could give you a chance to renegotiate.
  • Act Early: The sooner you get advice, the more options you have. If you’re planning to enter a major contract, or feel you may be disadvantaged by a ratchet clause, seek legal guidance before you’re locked in.

Key Takeaways: Ratchet Clauses in Australian Business Agreements

  • Ratchet clauses restrict how much prices, rents, or values in a business contract can decrease, often locking figures at their highest past amount.
  • They’re common in commercial lease agreements, investment deals, and some supplier or franchise contracts.
  • Always check whether a ratchet clause is “upward only” or allows some decreases - upward only clauses usually favour the landlord or supplier.
  • Not all ratchet clauses are enforceable (especially in some retail leases), so be aware of local laws and statutory protections.
  • You can and should negotiate these clauses - alternatives like partial ratchets or caps can provide more flexibility and fairness.
  • Reviewing your contracts with a legal expert protects your interests and helps you avoid costly surprises.
