Most business owners understand that a loan involves borrowing money and paying it back with interest. Beyond that baseline, the mechanics become less clear.
How does a lender decide what rate to charge? What is the actual difference between secured and unsecured? What does the comparison rate actually represent? What happens if you repay early?
These are the questions this article answers, in language that assumes no prior finance background.
The Basic Mechanics of a Business Loan
A business loan begins with an agreement. The lender provides a sum of money. The business agrees to repay that sum over a defined period, with interest calculated on the outstanding balance.
Three numbers define every business loan: the principal, which is the amount borrowed; the interest rate, which is the cost of borrowing expressed as a percentage of the outstanding balance per year; and the term, which is how long the business has to repay.
These three numbers interact to produce a fourth: the repayment amount the business must meet at each scheduled interval, whether daily, weekly, monthly, or quarterly.
A simple example. A business borrows $100,000 at 12% per annum over three years, with monthly repayments. The monthly repayment is approximately $3,321. Over three years, the business repays a total of approximately $119,556. The difference between the total repaid and the original $100,000 borrowed is the interest cost: $19,556.
The higher the interest rate, the higher the total cost. The longer the term, the lower each individual repayment but the higher the total interest paid. These two variables pull in opposite directions, which is why choosing the right term is not simply a question of minimising the monthly repayment.
Secured vs Unsecured: What the Difference Actually Means
Secured business loans require the borrower to pledge an asset as collateral. If the business fails to meet repayments and cannot resolve the default, the lender has the legal right to take possession of the collateral and sell it to recover the outstanding debt.
Common forms of security in Australian business lending:
Real property is the most valuable and most commonly requested security. Residential or commercial property pledged as collateral allows the lender to register a mortgage over the title. If the business defaults, the lender can force a sale.
Equipment or assets purchased with the loan serve as their own security in asset finance. A chattel mortgage over a piece of equipment gives the lender the right to repossess and sell the asset if repayments are not met.
A director guarantee means the director personally agrees to be liable for the loan if the business cannot repay. It is not a physical asset, but it converts business debt into personal obligation.
Unsecured business loans require no specific collateral. The lender extends credit based on the business's cash flow, the director's personal credit profile, and their assessment of the probability of repayment. Without collateral, the lender has limited recovery options if the business defaults, which is why unsecured loans carry higher interest rates than secured ones.
The practical implication: offering security reduces the lender's risk, which reduces the interest rate the business pays. Removing security increases the rate. Choosing between secured and unsecured involves weighing the cost difference against the risk of pledging personal or business assets.
How Interest Rates Are Calculated
An interest rate on a business loan in Australia can be expressed in two ways.
The headline rate, sometimes called the nominal rate or the annual percentage rate (APR), is the rate applied to the outstanding loan balance to calculate interest. For a loan at 10% per annum, the monthly interest charge is 10% divided by 12, or approximately 0.833%, applied to the outstanding balance.
The comparison rate includes the headline interest plus the loan's standard fees and charges, expressed as a single percentage. Establishment fees, monthly account fees, and certain other charges are factored into the comparison rate calculation. Two loans with the same headline rate but different fee structures will have different comparison rates.
The comparison rate is a more accurate representation of the true cost.

Always ask for the comparison rate when comparing business loan products.
One important limitation: the comparison rate is calculated on a standardised loan amount and term for comparison purposes. It does not account for early repayment fees, missed payment fees, or features that affect the cost in your specific situation. Read the loan contract rather than relying solely on the comparison rate.
Variable vs Fixed Interest Rates
Business loans in Australia are available with either fixed or variable interest rates, and the choice has real consequences.
Fixed rate means the interest rate is locked for the agreed term. Monthly repayments are predictable and do not change if market interest rates move. The security of a fixed rate is most valuable in a rising rate environment. The cost is that if market rates fall, the business continues paying the higher fixed rate and may face break costs for repaying or refinancing early.
Variable rate means the interest rate moves with market conditions, typically the RBA cash rate plus a margin. Monthly repayments can rise or fall. A variable rate benefits the business if rates fall and creates pressure if rates rise. Most business overdraft and line of credit facilities are variable. Many term loans offer the choice between fixed and variable at origination.
For businesses that need certainty in cash flow planning, fixed rates provide that predictability. For businesses that are confident rates will fall or that plan to repay early, a variable rate may produce a lower total cost.
What Early Repayment Actually Costs
Many business owners assume that repaying a loan early saves interest, because they are clearing the debt faster. This is true for variable rate loans and for some fixed rate products. It is not universally true.
For fixed rate loans, early repayment often triggers a break cost. The lender structured its funding around the agreed repayment schedule. Early repayment disrupts that structure, and the lender passes the cost of unwinding it to the borrower. Break costs can be significant, sometimes amounting to several months of interest, depending on how far through the term the loan is and the direction interest rates have moved.
For variable rate loans, break costs are usually absent or minimal. The lender's funding is not locked to the same degree. Repaying early on a variable rate facility typically saves the remaining interest with no penalty.
For merchant cash advances and revenue-based finance products, early repayment does not reduce the total cost at all. The fee is fixed at origination as a multiple of the advance amount. Paying it back in three months instead of six months clears the obligation faster but does not change the dollar amount owed.
Read the early repayment provisions in any loan contract before signing. They are not always prominently explained by lenders during the sales process.
What Happens if You Miss a Repayment
Missing a scheduled business loan repayment triggers a sequence of events.
In the first instance, most lenders charge a late payment fee. The amount varies by lender and product, typically $50 to $300. The missed payment is noted on the lender's internal records.
If the payment is not made within a short period (usually one to five business days), a formal notice of default is issued. This note may be recorded on the business's or director's credit file, depending on the lender's reporting practices.
Continued non-payment after a formal default notice leads to enforcement action: collection contacts, referral to debt recovery agencies, and ultimately legal action. For secured loans, the lender can apply to take possession of the security asset.
Missing a repayment is not automatically catastrophic. Contacting the lender proactively before a scheduled repayment cannot be met consistently produces better outcomes. Understanding how the business loan process works from the lender's perspective helps you manage that conversation effectively. almost always produces a better outcome than missing it without notice. Lenders have hardship policies, and most will work with a borrower who communicates early rather than going silent. GPS Finance manages lender relationships on behalf of every client
Frequently Asked Questions
What is the difference between a business loan and a line of credit?
A business loan provides a fixed sum that is repaid in set instalments over a defined period. Once repaid, the facility is closed. A line of credit provides access to a revolving limit: draw what you need, repay as revenue arrives, draw again. Interest applies to the outstanding balance rather than the full limit. A term loan suits a specific, one-time capital need. A line of credit suits ongoing or recurring working capital needs.
How does a lender decide what interest rate to charge?
Lenders price loans based on risk. Lower risk (strong trading history, clean credit, property security, adequate serviceability) attracts lower rates. Higher risk attracts higher rates. The base cost of the lender's own funding also factors in: when the RBA cash rate rises, lender funding costs rise, and lending rates typically follow. A business that improves its risk profile over time, by building trading history and maintaining clean credit, will access lower rates at renewal or refinance.
Can I negotiate the interest rate on a business loan?
Yes, particularly for larger deals and when applying through a broker with strong lender relationships. A broker who places significant volume with a lender may achieve better pricing than a direct applicant presenting the same deal in isolation. For deals above $500,000, rate negotiation is standard. For smaller amounts, the margin for negotiation is narrower but not zero.
What is a balloon payment on a business loan?
A balloon payment is a lump sum due at the end of a loan term, representing a portion of the principal that was not paid down during the regular repayment period. Monthly repayments are lower when a balloon is included because each payment covers less of the principal. At maturity, the business must pay the balloon through cash reserves, a refinance, or an asset sale. Equipment finance and vehicle finance frequently include balloon structures.
How does a personal guarantee affect my personal finances?
A personal guarantee converts a business debt into a personal obligation. If the business cannot repay and defaults, the lender can pursue the guarantor's personal assets, including a residential property, savings, or other personal assets. The guarantee is not triggered by the business having difficulty. It is triggered by formal default after the lender's standard enforcement process. Understand the precise terms of any guarantee before signing.
