Quick answer: A business applies for an amount and purpose, the lender assesses repayment capacity and risk, and approved funds are repaid under an agreed structure. The real cost depends on the amount, rate or fixed fee, term, repayment frequency, lender fees, security and early-payout rules.

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.
How a business loan works from enquiry to repayment
- Define the transaction. Set the amount, purpose, timing and how the funding should improve or protect business cash flow.
- Test serviceability and lender fit. The lender reviews income, expenses, existing debts, bank conduct, credit history, trading history and available security.
- Compare the actual structure. Check the amount advanced, rate or fixed fee, repayment frequency, term, establishment and ongoing fees, security and early-payout method.
- Meet approval conditions. Supply final documents and any asset, payout or settlement information the lender requires.
- Draw and repay. Funds are advanced and repayments begin under the contract. A revolving facility such as a line of credit works differently from a fully drawn term loan.
Have the amount, purpose, required date, recent turnover, existing repayments and preferred repayment term ready. That lets GPS Finance test a realistic pathway instead of comparing headline rates for products that may not fit.

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 its assessment of the probability of repayment. Without specific collateral, the lender has fewer recovery options if the business defaults. Depending on the borrower and product, that can mean different pricing, limits, terms or evidence requirements than secured finance.
The practical implication: suitable security can improve lender appetite or pricing, but it does not guarantee a lower rate. Choosing between secured and unsecured finance involves weighing cost, structure, speed and the consequences 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 can be more useful than a headline rate because it incorporates standard fees into a single figure where the comparison-rate rules apply. For a broader explanation of business-finance pricing, see business finance rates in Australia. For commercial facilities that do not use a consumer-style comparison rate, compare the actual fees and total repayment directly.
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, a market-value break cost may be less common, but discharge, administration, minimum-interest or early-termination charges can still apply. Repaying early may reduce future interest only after the contract's payout calculation and fees are checked.
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.
The immediate consequence depends on the contract and lender. A late fee or default interest may apply, and the missed payment will normally be recorded in the lender's account history.
If the payment remains unresolved, the lender may issue a formal notice, report information where permitted, restrict further drawings or begin collections. Timing and reporting differ by product, agreement and applicable law.
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. Contact the lender before the due date where possible, explain the problem accurately and ask what evidence or temporary arrangement is available. Understanding how the business loan process works helps you prepare that conversation. GPS Finance can also help a client organise the finance position and communicate with the relevant lender.
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?
Pricing may be negotiable where the transaction, borrower strength, security or competing lender options justify it. The scope to negotiate varies by lender and product, so compare the final structure rather than assuming a broker or loan size guarantees a discount.
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.
