Short answer: Secured business loans require an asset, often property or equipment, as collateral, and typically offer larger amounts and lower rates. Unsecured loans skip the specific asset but usually come with a director’s guarantee, smaller limits and a higher rate to offset the lender’s added risk.
Business owners comparing finance options often get stuck on the same question: is it worth putting up an asset as security to get a better rate, or is it better to keep things unencumbered and pay a bit more? There’s no universal answer, it depends on what you’re financing, how much you need, and what you’re comfortable putting on the line. This article sets out the practical differences so you can weigh the decision for your own situation.
What actually differs between secured and unsecured business loans?
The core distinction is whether the lender registers a mortgage or fixed charge over a specific asset as part of the loan agreement.
With a secured business loan, the lender takes a mortgage or charge over property, equipment or another nominated asset. If the loan isn’t repaid, the lender has a defined legal pathway to recover the debt through that asset. Because the risk is backed by something tangible, lenders can typically offer larger amounts, longer terms and lower interest rates.
With an unsecured business loan, no specific asset is mortgaged. The lender instead relies on the business’s cash flow and, in most cases, a personal guarantee from the director. This doesn’t mean there’s no security at all, lenders will often still register a general security interest over the business on the Personal Property Securities Register, but there’s no charge over a named asset such as your home or a piece of machinery.

Secured vs unsecured: a side-by-side comparison
| Feature | Secured loan | Unsecured loan |
|---|---|---|
| Collateral required | Yes, property, equipment or another specific asset | No specific asset, though a general security interest and guarantee usually apply |
| Typical loan size | Larger, often $100,000+ | Smaller, commonly up to $500,000 |
| Typical interest rate | Lower, reflecting reduced lender risk | Higher, reflecting increased lender risk |
| Approval speed | Slower, often requires valuation | Faster, sometimes within days |
| Risk to the borrower | Asset can be repossessed on default | Personal guarantee still creates personal liability |

How does security affect the interest rate you’re offered?
Interest rates are largely a function of risk, and security is one of the biggest levers a lender has to manage that risk. When a loan is secured against a valuable, liquid asset like commercial property, the lender’s potential loss in a default scenario is limited by the asset’s resale value. This generally translates into a lower rate.
Unsecured lending removes that backstop, so lenders price in the extra risk through higher rates and shorter terms. The gap between secured and unsecured pricing can be substantial, sometimes several percentage points, which is why it’s worth running the numbers on both structures before assuming unsecured finance is automatically more convenient. Our guide to business loan interest rates in Australia breaks down how these factors combine to set pricing.
Which structure suits your business? A decision framework
A few practical questions can help narrow down the right choice:
- Do you own suitable collateral? If you own commercial or residential property, or valuable equipment, a secured structure is usually available and often cheaper.
- How large is the amount you need? Larger facilities are generally easier to justify securing, since the rate saving compounds over a bigger balance.
- How quickly do you need funds? If timing is tight, unsecured finance generally moves faster because there’s no valuation or mortgage registration to arrange.
- How comfortable are you with the asset being at risk? Securing a loan against your home or key equipment is a genuine risk if the business underperforms, and that comfort level matters as much as the numbers.
Many businesses use a mix over time, starting with unsecured finance for smaller, shorter-term needs and moving to secured facilities as the business grows and larger funding requirements arise. If you’re already carrying a mix of both and want to simplify, our guide on how to refinance a business loan covers when consolidating makes sense.
Can you combine secured and unsecured finance?
Yes, and many businesses do. It’s common to hold a secured facility, for example a commercial property loan or an equipment mortgage, alongside a smaller unsecured line for working capital or short-term needs. Lenders generally assess each facility on its own merits, though your total debt load across all facilities will factor into how much further borrowing capacity you have.
Security interests registered against a business are publicly searchable through the Personal Property Securities Register, which lenders check as part of assessing new applications. If you already have registered security in place from an earlier loan, it’s worth mentioning this upfront when applying for further finance, since it affects how a new lender views their position.
It is also worth remembering that the secured versus unsecured decision is not always all-or-nothing at the point of application. Some lenders will offer a hybrid arrangement, for example a lower loan-to-value secured facility for the bulk of the funding requirement, topped up with a smaller unsecured component to cover the gap. This can be a way to access a competitive blended rate without offering security for the entire amount, though not every lender structures facilities this way, so it is worth asking specifically if a blended approach interests you.

Frequently asked questions
Is a secured business loan always cheaper than an unsecured one?
Not always, but it’s the general pattern. Secured loans typically carry lower rates because the lender’s risk is reduced, though the actual pricing depends on the lender, the asset offered and the strength of the application. It’s worth comparing specific offers rather than assuming.
What happens to the asset if I default on a secured business loan?
If a secured loan goes into default, the lender generally has the right to take possession of and sell the secured asset to recover the outstanding debt, following the process set out in the loan agreement and relevant legislation. This is a serious consequence, so it’s important to only secure a loan against an asset you’re confident you can service.
Do unsecured business loans still involve any risk to personal assets?
Yes, typically. Most unsecured business loans require a personal guarantee from the director, which means personal assets can potentially be pursued if the business defaults and the guarantee is called upon, even though no specific asset was mortgaged upfront.
Can I switch from an unsecured loan to a secured one later?
This is usually done through refinancing rather than converting the existing loan. If your business grows or acquires suitable collateral, refinancing into a secured facility may allow access to a lower rate or larger amount, subject to a fresh application and approval.
Does having an existing secured loan affect my ability to get unsecured finance?
It can. Lenders assessing a new unsecured application will typically look at your total existing debt commitments, including secured loans, to determine what additional repayments the business can service. Existing security registered on the business may also be considered as part of the assessment.
