Secured vs Unsecured Business Loans: What's the Difference?

A secured vs unsecured business loan comes down to whether you pledge an asset to back the borrowing. Secured loans use property, equipment, or other collateral to reduce the lender's risk, which typically means lower rates starting from around 6.8% p.a. Unsecured loans skip the collateral but charge more, with rates generally ranging from 9.5% to 18% p.a. in 2026.

Why the distinction matters in 2026

With the RBA cash rate at 4.35% following three increases this year, business borrowing costs have risen across the board. The gap between secured and unsecured business loans has widened as lenders price risk more carefully. According to the RBA's March 2026 Financial Stability Review, banks have increased partially secured and unsecured lending, but the rate premium for going unsecured remains significant: typically 3 to 6 percentage points above a secured equivalent.

Key differences at a glance

Secured loans average 4.5 times the size of unsecured equivalents, according to RBA data. That size gap reflects the lower risk lenders carry when they hold security.

What a $100,000 loan actually costs

The rate difference is not abstract. Here is what a $100,000 business loan costs under each structure over three years.

That $10,224 premium is the price of speed and no collateral. For some businesses, the trade-off makes sense. For others, it does not.

When a secured loan is the better option

A secured business loan suits borrowers who have assets available and need larger amounts or longer terms. If you are buying commercial property, funding a major equipment purchase, or refinancing existing debt, secured finance will almost always be cheaper over the life of the loan.

Lenders are also more flexible on eligibility when security is involved. Businesses with shorter trading histories or uneven cash flow can often qualify for a secured loan where they would be declined for unsecured finance.

When an unsecured loan makes more sense

Speed is the main advantage. Many non-bank lenders approve unsecured business loans within 24 to 48 hours, compared to weeks for a secured facility that requires property valuations and legal work.

Unsecured finance is practical when you need working capital quickly, want to cover a short-term gap, or simply do not have (or do not want to risk) property as security. It also avoids the legal costs of registering a mortgage or charge over an asset. If you operate as a sole trader, unsecured loans are often the most accessible option since many sole traders do not hold business assets suitable for security.

The personal guarantee question

"Unsecured" does not always mean risk-free for the borrower. Around 59% of Australian small businesses use a personal guarantee when borrowing, and most unsecured business lenders require one from each director.

A personal guarantee means the director is personally liable if the business cannot repay. This can extend to personal property, savings, and other assets. The guarantee can be limited (capped at a percentage of the facility, sometimes as low as 20%) or unlimited (full liability for the entire debt).

Before signing, check whether the guarantee is limited or unlimited, whether it is joint and several (each guarantor liable for the full amount, not just their share), and what assets could be at risk. If you are comparing an unsecured loan with a full personal guarantee to a secured loan backed by business equipment only, the unsecured option may actually carry more personal risk.

How lenders assess each type differently

For secured loans, the lender's primary concern is the value and quality of the collateral. They will order a valuation, check the loan-to-value ratio, and assess whether the asset could be sold to recover the debt. Your cash flow matters, but the security provides a safety net.

For unsecured loans, cash flow is everything. Lenders focus on your bank statements, revenue consistency, and trading history. A business turning over $120,000 per year with steady monthly deposits is a stronger applicant than one with $200,000 in irregular, lumpy income. Most unsecured lenders want a minimum of 6 to 12 months of trading history.

A business line of credit is another unsecured option worth considering if your cash flow needs are ongoing rather than one-off. It gives you flexible access to funds without the commitment of a fixed loan term.
