The True Cost of Unsecured Business Lending in Australia

Unsecured business lending in Australia has a reputation for speed: no property on the line, minimal paperwork, funds in your account within days. For a business owner under cash flow pressure, that pitch is difficult to resist.

But it is also among the most expensive forms of capital available to Australian businesses — and the true cost is rarely communicated clearly upfront.

This article breaks down what unsecured lending actually costs, where the risk sits, and when it makes sense versus when it quietly destroys the financial health of a business.

What "Unsecured" Actually Means

An unsecured business loan is one where the lender holds no registered security interest over a specific asset. There is no mortgage over property, no charge over equipment, no specific collateral the lender can immediately recover against if you default.

What lenders do typically hold is a personal guarantee from the business owner, and often a General Security Agreement (GSA) over the assets of the business as a whole. So while the loan is described as "unsecured" in the retail sense, the personal liability and business exposure are very real.

The absence of specific collateral does not mean the lender is taking on more risk without compensation. It means you are.

The Rate Reality

The rate gap in unsecured business lending is the clearest sign of where the risk actually sits. Secured commercial loans — those backed by property or other tangible assets — typically sit in the range of 6–9% per annum for creditworthy borrowers in the current environment. Asset-backed equipment finance is comparable. These figures are illustrative and deal-dependent.

Unsecured business loans from non-bank lenders frequently carry rates between 18–48% per annum, with some short-term facilities priced even higher when fees are annualised — in the facilities we regularly review, the higher end is common on shorter terms.

The fee structures are also worth examining carefully:

• Origination fees of 1.5–3% charged upfront
• Monthly account fees applied regardless of usage
• Early repayment penalties that eliminate any benefit of paying the loan down faster
• Factor rates (common in merchant cash advances) that express cost as a multiplier rather than an interest rate — specifically to obscure the true annualised rate

As an illustrative example: a factor rate of 1.35 on a $100,000 advance means you repay $135,000. If that advance is repaid over six months, the annualised cost exceeds 70%. It rarely appears that way in the marketing material.

When Unsecured Lending Is Positioned as the Only Option

Business owners are frequently told they have no choice. The bank said no. The application will take too long. The deal needs to move now.

Sometimes that is true. But more often, it reflects one of two things:

1. The application was poorly structured — banks and secured lenders have specific requirements for how business financials, projections, and purpose of funds are presented. A loan that fails at one lender in one form can succeed at another lender with a properly prepared submission.
2. The right lenders were never approached — in our experience arranging this type of finance, well over 50 non-bank lenders are active across commercial property, business lending, and development finance. Many offer secured facilities with rates and terms that bear no resemblance to the unsecured market.

Speed is the most common justification for expensive unsecured capital. But a 30-day timeline is rarely as urgent as it feels in the moment, and the cost of carrying a 35% facility for 18 months while you find time to refinance is significant.

The Compounding Effect on Business Cash Flow

The true cost of unsecured lending extends beyond the interest rate. When repayments are structured as daily or weekly debits — common in the online lending market — the impact on working capital can be severe.

Take a $250,000 unsecured facility at 28% per annum with daily repayments over 18 months: that works out to roughly $900 in repayments per business day. For a business turning over $3M annually, that is a meaningful daily cash drain before wages, rent, or supplier payments are made. Illustrative example, deal-dependent.

Businesses that enter unsecured lending arrangements under pressure frequently find themselves refinancing — often at equally poor terms — because the repayment schedule prevents them from building the reserves needed to qualify for better facilities.

This is the cycle that unsecured lending creates for undercapitalised businesses. It is worth understanding before entering it.

Where Unsecured Lending Does Make Sense

This is not an argument against unsecured lending categorically. There are circumstances where it is appropriate:

• Short-term bridging where the repayment source is certain and imminent (a debtor invoice, a contract milestone, a known settlement)
• Working capital smoothing for businesses with strong, recurring revenue and genuine short-term timing mismatches
• Opportunistic capital deployment where the return on the funded activity materially exceeds the cost of the facility

The test is simple: does the funded activity generate a return — directly or indirectly — that justifies the cost of capital? If the answer is genuinely yes, and the repayment is structured to match cash flow, unsecured lending can be a useful tool.

If the answer is "we need it to stay afloat," that is a different conversation entirely — and one that typically requires a more fundamental review of the business's capital structure.

What to Do Before Signing

Before accepting an unsecured facility, any business owner should know:

1. The annualised percentage rate (APR) — not the factor rate, not the monthly rate. The APR.
2. The total repayment amount — what does the lender receive in total if you hold the facility to term?
3. The daily or weekly repayment impact — model it against your actual bank statements, not projected revenue.
4. Whether secured alternatives exist — have you been declined everywhere, or only at your primary bank?
5. What security you are actually providing — read the personal guarantee and GSA carefully.

The time invested in understanding these five points before signing is considerably less than the time spent managing the consequences of an expensive facility that was the wrong fit.

A Note on Debt Structure

At Black Mountain Financial, we work with clients across commercial property, development finance, and business lending — and we see the downstream consequences of poorly structured capital arrangements regularly.

Our role is not to place loans. It is to understand what a client is trying to achieve commercially, assess what capital structure serves that objective, and source the right facilities from the right lenders at appropriate cost.

That sometimes means recommending unsecured working capital. More often, it means finding secured alternatives that the client did not know were available to them.

If you're weighing unsecured business lending options against secured alternatives, speak to us for an independent view before committing.

Black Mountain Financial is a debt advisory practice based in Canberra, providing commercial and residential finance solutions to business owners, property developers, and professional services firms across the ACT and regional NSW.
