A personal guarantee is the director's promise to repay a business loan or overdraft personally if the business cannot. Almost every lender in Australia requires one, including on unsecured facilities. It is not a mortgage over your home, it does not appear on your credit file unless called upon, and the practical risk is capped by how much you draw.
If you've started researching business finance in Australia, you've almost certainly come across the term "personal guarantee." It sounds serious - and it is. But it's also standard practice across the industry. Here's exactly what you're agreeing to and what it means in practice.
What is a personal guarantee?
A personal guarantee is a legal commitment from the business owner or director to personally repay the business loan if the business cannot meet its obligations. In simple terms: if your business defaults on the loan and can't repay, you personally become responsible for the debt.
This applies to both business overdrafts and business loans, and to both secured and unsecured facilities. A personal guarantee is separate from property security - you can have both, or just a personal guarantee without security.
Key point: A personal guarantee does not appear on your personal credit file unless it is called upon - i.e. unless the business defaults and the lender enforces the guarantee. Simply signing a guarantee doesn't affect your personal credit score.
Why do lenders require personal guarantees?
Lenders require personal guarantees because:
- A company can be wound up with limited recourse for the lender - a personal guarantee ensures there is a personal party liable
- It creates alignment - a director who has personally guaranteed a debt has a strong incentive to ensure repayments are made
- For small businesses, the owners and the business are closely intertwined - separating personal and business risk is often artificial
What does signing a personal guarantee mean in practice?
In practice, signing a personal guarantee means:
- If your business makes all repayments on time - nothing happens. The guarantee is never called upon and has no practical impact.
- If your business misses repayments, the lender will first pursue the business. Most lenders will work with you to find a solution - payment plan, restructure, etc.
- If the business cannot repay and formal recovery action commences, the lender can pursue you personally - potentially including your personal assets.
How to manage personal guarantee risk
- Only borrow what you need - don't take a $200,000 facility when $80,000 will do the job
- Maintain a repayment buffer - keep enough in your business account to cover 2-3 months of repayments if revenue drops
- Read the guarantee document carefully - understand whether it's limited (capped at the loan amount) or unlimited (covers all amounts owed to the lender under any facility)
- Get independent legal advice on the guarantee document for large facilities
- Consider insurance - some business finance products offer loan protection insurance that covers repayments in the event of serious illness, injury or death
Can I negotiate the personal guarantee?
For standard SME facilities, personal guarantees are non-negotiable with most lenders. However, for larger facilities, you may be able to negotiate whether the guarantee is limited (capped) or unlimited, and whether multiple directors share the guarantee equally rather than one director carrying it all.
What does a personal guarantee cost you in a worst case? Worked scenario
A labour hire business takes an $80,000 unsecured business overdraft. Eighteen months later its main client goes into administration with $50,000 drawn on the facility and the business cannot trade on. Here is how the guarantee plays out.
| Question | Limited guarantee (capped at the facility) | Unlimited guarantee |
|---|---|---|
| What is the director liable for? | The $50,000 drawn plus accrued interest and reasonable enforcement costs, never more than the $80,000 facility limit | Everything owed to that lender under any facility, including a second loan taken later |
| Is the family home automatically at risk? | No. There is no mortgage or caveat. The lender must first obtain a judgment, then pursue assets | Same process, but the amount pursued can be larger |
| What reduces the exposure? | Drawing only what the job needs; the undrawn $30,000 was never a liability | Keeping other facilities with the same lender to a minimum |
| Does it hit the credit file? | Only once the guarantee is called and the debt is listed | Same |
Before you sign: a six-point check
- Confirm whether the guarantee is limited to the facility amount or unlimited, and ask for limited
- Check that every director is named, and how liability is shared between them
- Read the events-of-default clause: late BAS or a missed repayment can trigger the facility before the business has actually failed
- Size the facility to the real gap; a $50,000 limit you fully use carries less guarantee exposure than a $150,000 limit you rarely need
- Keep two to three months of repayments in reserve so a slow month never becomes a default
- Get independent legal advice on any guarantee over $150,000 or where property is involved
Fixed-term facilities carry the same guarantee; the comparison is in our guide to working capital loans.
Frequently asked questions
Does a personal guarantee mean my home is at risk on an unsecured loan?
Not directly. An unsecured business overdraft has no mortgage or caveat over your property. If the business defaults and the lender enforces the guarantee, it becomes a personal debt that the lender can pursue like any other, which could eventually involve your assets through the courts. The guarantee is a promise, not a registered security, and the distinction matters.
Can I get a business loan without a personal guarantee in Australia?
For standard SME facilities, rarely. Lenders on the OverdraftMe panel require a director guarantee on both secured and unsecured products. What you can negotiate on larger facilities is whether the guarantee is limited to the facility amount and whether it is shared equally between directors.
Does a personal guarantee show on my credit file?
Signing one does not create a listing. It only touches your personal credit file if the business defaults and the lender calls on the guarantee. Applying for the facility itself does create a credit enquiry, which is why OverdraftMe submits one application to one lender rather than several.
