The Real Cost of Secured vs Unsecured Working Capital
Secured working capital is usually cheaper than unsecured, but the price you pay is set by more than the headline rate. Here is how lenders weigh security, term and fees so you can read the real cost before you commit.
Quick Answer
Secured working capital is usually cheaper than unsecured because property security lowers the lender's risk. The headline rate is only part of it, the term and the setup fees decide the real dollar cost, so weigh all three on a working capital facility.
Is secured working capital actually cheaper?
Usually yes, but the rate alone does not tell you the price. When a lender holds property security, the loss they face if a deal goes wrong is smaller, so the price of capital follows the security. That lower risk shows up as a lower rate and a longer available term on a secured working capital facility than you would see on an unsecured one.
The reframe worth making is that "cheaper" is a total-dollar question, not a rate question. An unsecured facility skips the valuation and legal work, so it can be the cheaper choice for a small, short drawdown even when its rate looks higher. What a lender weighs before the rate is the security and the exit, and that is the same lens you should use when you compare the two. The Australian Government's guide to business funding is a useful neutral starting point on the broader options.
Where the cost actually sits
The cost of any working capital facility breaks into three parts: the rate, the one-off setup, and the term you hold it for. Secured and unsecured pull on those three levers differently, which is why a single rate comparison can mislead. Here is how the two stack up across the lines that move the dollar cost.
Read that bottom row carefully. Secured working capital is typically lower cost where equity supports it, but the establishment and legal costs are approximate and deal-by-deal, so a small, fast drawdown can still come out ahead unsecured once you add the setup back in. It is the classic trade of unsecured speed versus secured cost.
When each one is the stronger fit
The choice is rarely about the rate in isolation. It is about how large the need is, how long you will hold it, and whether you have property security you are willing to put behind the facility. The split below is how the choice usually resolves once the numbers are on the table.
Secured is the stronger fit
- The amount is sizable and you will carry it for months, not weeks
- You hold usable property equity, including behind a first mortgage
- A lower rate over a longer term genuinely eases the cashflow cycle
- You can wait the extra days for valuation and security work
Where secured gets tricky
- The need is small and short, so setup costs swamp the rate saving
- You need funds in days and cannot wait on a valuation
- The equity is thin once existing debt is counted
- There is no clear exit, so a longer term just grows the interest
If the equity is there but you do not want to disturb your home loan, a second mortgage can sit behind the first to fund working capital at a secured price. For a faster, property-backed bridge over a short gap, a caveat loan trades a higher cost for speed.
Why the term, not just the rate, sets the bill
The most common costing mistake is reading the rate and stopping there. Term length changes the total dollar cost, not just the rate: a lower rate held across a longer term can still cost more in total interest than a higher rate cleared quickly. A secured facility usually gives you the longer term, which is a cashflow benefit, but it only stays a saving if you do not let the balance drift.
That is why the exit strategy matters as much as the price. Match the term to how the cash actually returns to the business, whether that is a debtor cycle, a seasonal lift, or a settlement, and the total cost stays close to the headline. With working capital in particular, the cheapest facility on paper is rarely the cheapest one you actually hold. A quick eligibility check and a read of our business loan definitions guide will help you frame the comparison before you choose.
Secured working capital is usually the cheaper option on rate, but the real cost is the rate, the setup and the term read together. A sizable, longer need favours secured, while a small, urgent gap can be cheaper unsecured once the establishment and legal costs are added back. For owners with property equity, a second mortgage often delivers the secured price without refinancing the first.
Key takeaway: Compare the all-in dollar cost over the term you will actually hold, not just the headline rate.Frequently Asked Questions
A secured business loan is usually cheaper than an unsecured one, because property security lowers the lender's risk and that shows up as a lower rate and a longer term. The trade-off is speed and setup, since a secured facility needs a valuation and legal work that an unsecured facility skips. For an equity-backed option, a second mortgage can sit behind your existing home loan to fund working capital.
Secured working capital costs less because the lender holds property security, so the price of capital follows the security rather than your cashflow alone. With an asset behind the facility a lender can offer a lower rate and a longer term, which reduces the total dollar cost. You can read how the security is assessed on our working capital loans page.
Establishment and legal costs on a secured working capital facility are approximate and deal-by-deal, because they cover valuation, documentation and registering the security against the property. Those one-off costs are why a short, small drawdown can be cheaper unsecured even when the secured rate looks lower. A broker can model the all-in cost before you commit, and our working capital glossary entry explains the terms you will see.
A longer term changes the total dollar cost of a working capital loan, not just the rate, because you pay interest across more months even when each repayment is smaller. A secured facility usually offers the longer term, which helps cashflow but can raise the total interest if you carry the balance. Matching the term to your exit strategy keeps the total cost in check.
You can use a second mortgage for working capital, releasing equity that sits behind your first mortgage to fund operating cash without refinancing the whole loan. It is a secured option, so it usually prices lower than unsecured working capital while keeping your existing home loan in place. Our second mortgage loans page sets out how the priority and exit are structured.
