Small businesses paid an average business lending rate of 7.33% in Australia on 28 February 2025, while large businesses paid 5.49%, so there isn't one business loan interest rate that applies to every borrower. The rate you're offered depends on your business size, security, loan structure and the lender's assessment.

A Sydney business owner can receive two quotes for a similar borrowing amount and find the rates several percentage points apart. One quote may be secured against property, while the other may be unsecured working capital. Both numbers can be genuine, because Australian business lending is a segmented market rather than a single price list.

Why Two Businesses Get Very Different Rate Quotes

The first question isn't “What's the current business loan rate?” It's “What type of borrowing am I comparing?”

The Reserve Bank of Australia's F7 business lending dataset recorded an average rate of 7.33% for small business lending, 6.15% for medium business lending and 5.49% for large business lending on 28 February 2025. The small business rate was therefore about 1.84 percentage points higher than the large business rate in the same national dataset. The Australian business loan rate data and size comparison show why a headline rate can be misleading.

The gap reflects how lenders assess scale, risk and repayment capacity. A larger business may have more established financial information, broader revenue sources and greater borrowing capacity. A smaller business may be more exposed to one owner, one practice, one contract or a narrow customer base.

Practical rule: Compare like with like. A secured term loan, an unsecured cash-flow facility and an overdraft are different products, even if each is described as business finance.

This article is for small and medium business owners, medical professionals, not-for-profit organisations and new migrants establishing a business in Australia. It focuses on how pricing works and how you may compare loan structures without chasing one supposedly universal rate. If you're weighing a lender against a bank, the decision may also involve service, documentation and structure, as outlined in this comparison of a mortgage broker and a bank.

Currency note: This article reflects Australian rules, thresholds and regulator guidance current as at 10/2026.

How Business Loan Interest Rates Are Set

A business loan interest rate is the percentage charged on the amount borrowed. The lender generally builds that price from its funding cost, a risk margin and the features of the facility.

A base rate or funding rate is the underlying cost used to price lending. A risk margin is the additional amount added to reflect factors such as credit quality, security, loan term and repayment uncertainty. A comparison rate combines the interest rate with certain fees and charges into one percentage, helping borrowers compare the broader cost of similar products.

The exact process differs between lenders, but the logic is similar:

  1. Funding cost: The lender considers what it costs to obtain and maintain funding.
  2. Risk assessment: The lender reviews the business, owner, cash flow and credit history.
  3. Security and structure: Secured lending may be priced differently from unsecured lending, while an overdraft may carry a different rate from a fixed term loan.
  4. Loan terms: The amount, term, repayment pattern and proposed use of funds affect the quote.
  5. Offer confirmation: The final rate and conditions are confirmed in the Letter of Offer.

A useful analogy is insurance. An insurer prices cover according to the likelihood and potential cost of a claim. A lender prices credit according to the likelihood of repayment, the quality of available security and the consequences if repayment becomes difficult. A broader explanation of how banks calculate funding costs is available in this bank cost of funds guide.

The Australian market shows why structure matters. In 2026, selected secured business loan options were reported from 6.79% p.a. to 7.99% p.a., while unsecured business finance started at about 10.95% p.a. The same official interest-rate reference material listed Westpac's Small Business Loan Rate at 7.91% p.a. and NAB's Business options prime rate at 7.85% p.a. The Reserve Bank of Australia's interest-rate information also records higher pricing for products such as NAB's business overdraft prime or benchmark rate of 10.72% p.a. and invoice finance indicator rate of 9.61% p.a.

The decision is practical. Ask the lender which part of the quote comes from the base rate, which part is the risk margin, whether the rate can change, and what fees are included in the comparison rate.

Fixed, Variable and Comparison Rates Explained

A fixed rate stays unchanged for the agreed fixed period, subject to the loan terms. A variable rate can move when the lender changes its reference pricing or when relevant funding conditions change. A comparison rate is a broader cost measure that combines the interest rate with specified fees and charges.

The three rates answer different questions. Fixed pricing asks, “How predictable are my repayments?” Variable pricing asks, “How much flexibility do I have if market conditions change?” Comparison pricing asks, “What may this facility cost once the listed fees are included?”

An infographic explaining the differences between fixed, variable, and comparison interest rates for financial loans.

Fixed rates

A fixed rate may suit a borrower who values predictable repayments and has a cash-flow plan built around stable debt costs. The trade-off is that a fixed borrower may not benefit if variable rates later fall. Early repayment or refinancing can also involve conditions or costs, depending on the Letter of Offer.

Variable rates

A variable rate may suit a business that can tolerate changing repayments and wants greater flexibility. Variable borrowers are exposed to rate resets, which may place pressure on an overdraft or working-capital facility when cash flow is already tight.

Comparison rates

A comparison rate can help identify a product with a lower overall cost than another product carrying the same advertised interest rate. It may not capture every circumstance, however, and borrowers should still check establishment fees, ongoing fees, valuation costs, security costs and early repayment conditions.

A rate is only meaningful when the repayment structure, fees, term and security are also clear.

Calculating What a Business Loan Really Costs You

The cost of borrowing depends on four inputs: the principal, the interest rate, the term and the repayment method. The principal is the amount borrowed. The term is how long the facility remains outstanding. A longer term may reduce each scheduled repayment while increasing the total interest paid over the life of the facility.

Consider Dr Anya Sharma, a sole-trader GP in Sydney. Dr Sharma is considering finance for practice equipment and is comparing a secured term loan with unsecured business finance. A secured option may have a lower quoted rate because the lender has an asset supporting the facility. An unsecured option may be simpler in structure, but the lender may price the absence of security through a higher margin.

Dr Sharma should ask for the same information from each lender:

The verified market data does not provide a principal, term or product-specific repayment schedule for Dr Sharma, so a responsible calculation cannot produce a monthly repayment or total interest amount without inventing facts. The table below instead shows how to compare the available rate information before requesting a formal repayment schedule.

Loan typeIndicative rateTermApprox. monthly repaymentApprox. total interest
Secured business lendingFrom 6.79% p.a. to 7.99% p.a. in selected 2026 optionsConfirm with lenderRequires principal and termRequires principal, term and fees

Business overdraftAround 10.72% p.a. for the cited NAB benchmarkRevolving facilityDepends on amount drawn and time outstandingDepends on usage and fees

The difference between secured and unsecured pricing can materially change the cost of equipment finance. Dr Sharma may therefore compare the total cost of each structure, the value of the equipment, the security offered and the effect of repayments on practice cash flow, rather than selecting the lowest advertised number in isolation.

What Lenders Look at When Pricing Your Loan

Lenders generally price a business loan after assessing the probability that the borrower can repay and the protection available if repayment becomes difficult. The assessment commonly considers personal and business credit history, the proposed security, loan-to-value ratio, cash flow, trading history and industry risk.

Credit history can influence both eligibility and pricing. Defaults, late payments, excessive credit enquiries or unresolved tax obligations may require explanation. A clean file doesn't guarantee a particular rate, but it gives the lender a clearer risk profile.

Loan-to-value ratio, or LVR, compares the loan with the value of the asset supporting it. A lower LVR may give the lender more protection because the asset provides a larger equity buffer.

Security type also matters. RBA analysis reported that, in June 2023, loans secured by residential property were around 50 basis points cheaper than other secured SME loans and roughly 3 percentage points cheaper than unsecured loans. The same analysis found average outstanding SME interest rates around 65 basis points higher than rates for large businesses. The relevant Australian business lending information illustrates why collateral and business scale can create measurable pricing differences.

Cash flow evidence helps a lender test serviceability, which means the business's ability to meet repayments from available income. The lender may review financial statements, tax returns, bank statements, forecasts, existing debts and the stability of revenue.

Before applying, a borrower may be able to improve the presentation of the application by reconciling accounts, explaining unusual transactions, updating forecasts and identifying the precise purpose of the funds. Everglow's Australian business loan requirements guide provides a starting point for organising that information.

Current Australian Market Trends Affecting Business Borrowing

Business loan interest rates can move after changes in the Reserve Bank of Australia cash rate, but the pass-through isn't identical across every product. Funding costs, lender margins and facility structure can also change the rate a borrower pays.

RBA data indicates that new variable rates declined in 2025 and increased in 2026 as short-term funding costs changed. Westpac also announced a 0.25% p.a. increase to cash-rate-linked business loans and overdrafts effective 9 October 2026. The related official announcement shows how lenders can link changes in eligible variable-rate products to an RBA cash-rate movement.

A 0.25% p.a. increase means the annual interest cost rises by 0.25% of the relevant outstanding balance, before considering repayments, fees and any change in the balance. The dollar effect depends on the amount outstanding. A borrower with a fully drawn overdraft therefore faces a different impact from a borrower using only a small portion of the available limit.

Overdraft and invoice-finance users may be particularly exposed because these facilities can be revolving or linked to indicator rates. The verified market information places business overdraft pricing around 8.11% to 10.72% p.a., invoice finance indicator rates around 9.61% p.a., and selected secured asset finance starting near 7.49% p.a. in 2026. Those figures are current as at 10/2026 and should be checked against the lender's current offer.

A business deciding between structures may find a useful broader perspective in this guide on funding the business. Everglow also outlines small business cash-flow lending as one possible funding structure, subject to assessment and circumstances.

Practical Strategies to Lower Your Business Loan Interest Rate

The most effective rate discussion often starts before the application. A borrower may reduce cost by selecting the right structure, presenting a stronger file and comparing the complete offer rather than negotiating only the headline rate.

Structure the borrowing around the purpose. A term loan may fit a defined purchase with regular repayments. An overdraft may provide flexibility for short-term working-capital movements. Asset finance may align the borrowing with equipment being acquired. The suitable structure depends on cash flow, asset life, repayment capacity and lender terms.

Consider whether security is appropriate. Residential property security may attract sharper pricing than unsecured borrowing, but offering property creates risk and should be considered carefully. A borrower should understand the security documents, guarantees, enforcement provisions and consequences of default before proceeding.

Prepare the evidence early. Current financial statements, tax returns, bank statements, debt schedules and a realistic cash-flow forecast may help a lender assess the application efficiently. A clear explanation of the borrowing purpose can also help distinguish productive finance from a facility being used to cover an unresolved cash shortfall.

Compare the full cost. Ask each lender for the interest rate, comparison rate, fees, repayment frequency, rate review terms and early repayment conditions. A lower headline rate may not mean a lower total cost if the facility includes substantial fees or a structure that doesn't suit actual usage.

Review tax treatment carefully. The Australian Taxation Office states that interest is deductible only while borrowed funds are employed in the business or another income-producing activity. If the funds stop being used for that purpose, the interest deduction may stop. The ATO ruling on interest deductions should be considered with the borrower's tax adviser.

Credit history can also affect the lender's assessment. Before approaching lenders, a borrower may review the file and address errors or unexplained issues using Everglow's credit score improvement guidance.

Sector Guidance, Common Questions and Next Steps

Medical professionals may have strong income but limited business assets during the early years of practice. SMEs may be more sensitive to variable repayments and revenue concentration. Not-for-profits may need to provide governance documents, funding information and evidence of sustainable cash flow. New migrants may need to explain a limited Australian credit history with clear business records, income evidence and information about the proposed enterprise.

Frequently asked questions

Are business loan interest rates tax deductible?

Interest may be deductible when borrowed funds are used in the business or another income-producing activity. The deduction generally follows the use of the funds, not just the name of the loan. If borrowed money is diverted to a private purpose, the tax treatment may change. Obtain advice for the actual structure and use of funds.

Is a secured business loan always cheaper?

A secured loan may carry a lower rate because the lender has security, but the overall cost depends on fees, term, valuation costs, guarantees and repayment conditions. Security also exposes the relevant asset to enforcement risk if the borrower defaults. Compare the complete offer rather than assuming that a lower interest rate is automatically preferable.

Should a business choose a fixed or variable rate?

A fixed rate may suit a business that prioritises repayment certainty, while a variable rate may suit a business that can tolerate movement and values flexibility. Neither structure is suitable for every borrower. Review cash-flow resilience, the expected borrowing period, break costs and the terms governing rate changes before acting.

Why can an overdraft cost more than a term loan?

An overdraft provides flexible access to funds, and the borrower may draw and repay amounts as working capital changes. That flexibility can be reflected in the pricing. The correct comparison depends on actual utilisation, available limit, fees and the period the balance remains outstanding.

Can a new migrant obtain business finance in Australia?

A new migrant may be able to apply for business finance, but a limited Australian credit history can make the lender's assessment more detailed. Clear identity documents, business records, Australian income evidence, a realistic forecast and an explanation of overseas experience may help the lender understand the application. Approval and pricing depend on the lender's criteria.

There is no single Australian business loan interest rate. The right approach is to compare the structure, security, repayment risk, fees and tax use of the funds, with the final decision depending on your circumstances.
