On 10 October 2026 CommBank published secured business loans from 7.54% p.a., Westpac its small business loan rate at 8.16% p.a. (effective 9 October) and NAB 12.95% p.a. fixed on QuickBiz. Each is a base rate plus a margin for your security, size and risk, and business loans carry no comparison rate because they sit outside the National Credit Code. Unsecured and online lending prices higher, so compare the total cost in dollars, fees included.
Business loan rates lenders publish
Starting rates and fees as each lender published them on 10 October 2026, after the RBA's 0.25 point rise of 30 September; CommBank and Westpac had passed it on in full. A starting rate is for the strongest file; your rate adds a margin for your security and risk.

Inclusion is editorial reference, not a recommendation. Rates change often, so we only show a rate we captured from the lender's own page in the last 60 days, with a link to that page; otherwise we link to the lender's rate card where it publishes one. The broker you are matched with compares the lenders on their own panel.
See all 22 business loan lenders- Rates are built as a base rate plus a margin: Westpac and BankSA publish base or indicator rates with a margin depending on security; NAB publishes prime rates and bank bill pricing periods
- Three pricing bases: variable (moves with the base), fixed (reverts to variable base plus margin at the end, Westpac) and bank bill (resets off the swap rate, NAB)
- No comparison rate: business lending is outside the National Credit Code, so compare total cost in dollars including establishment and line fees
- Published starting rates on 10 October 2026 ran from 7.54% p.a. secured (CommBank) to 12.95% to 13.09% p.a. unsecured at the banks, and from 15.5% APR on Lumi's line of credit
- What moves the margin: security type, LVR, trading history, financials, industry and credit; a 2% to 3% spread within one lender is normal
WARNING: This comparison rate is true only for the examples given and may not include all fees and charges. Different terms, fees or other loan amounts might result in a different comparison rate. Comparison rates are calculated on a secured loan of $150,000 over 25 years for home loans and a loan of $30,000 over 5 years for car and personal loans, unless the lender states another basis. Business loans and equipment finance for a business purpose have no mandatory comparison rate.
How is a business loan interest rate set?
As a base rate plus a margin. The base is the lender's published reference rate for that product and moves with its funding costs; the margin is the loading for your security, size and risk, and is the part that is negotiated.
Westpac publishes its business loan rates this way: an Overdraft Business Rate and a Small Business Overdraft Rate as bases, a 30-day bank bill rate as the base for invoice finance, and a note that a margin may apply depending on the type of security. BankSA publishes indicator rates to which a margin is added, and NAB a business overdraft prime rate, a QuickBiz prime rate and bank bill pricing.
The starting rates in the table above are the rates for the strongest profile; what none of the lenders publish is the rate you will get, because the margin is set on the file.
Fixed, variable or bank bill?
| Pricing basis | How it moves | What lenders publish | Best suited to |
|---|---|---|---|
| Variable | Rises and falls with the lender's base rate; repayments change | Westpac: repayments rise and fall with the rate; IMB publishes variable business rates by security type | Loans you may repay early or draw down and repay, such as overdrafts and lines of credit |
| Fixed | Held for an agreed term, then reverts | Westpac: reverts to a variable base rate plus any margins current at the time; ING commercial: fixed 1 to 5 years, extra repayments under $20,000 a year without break costs; NAB QuickBiz fixed for the term | Term loans and equipment where you want certainty on repayments |
| Bank bill | Resets off the bank bill swap rate each pricing period | NAB publishes pricing periods under and over 3 months; Westpac uses a 30-day bank bill rate for invoice finance | Larger commercial loans where the borrower wants market pricing and can manage resets |
What else do lenders publish about their rates?
Checked against each lender's published business rates page on 20 September 2026, with the CommBank, Westpac and ING rows re-checked on 10 October 2026. The point of this table is what each lender discloses about how its rates are built.
| Lender | What the rates page publishes | Margin disclosure | Other published detail |
|---|---|---|---|
| NAB | Business overdraft prime rate, QuickBiz prime rate, bank bill pricing for periods under and over 3 months | Customer margin applied to the prime rate on the file | Secured and unsecured business loans, terms 30 days to 15 years; QuickBiz overdraft to $50,000 |

| BankSA | Indicator rates by product; commercial loan rate marked no longer for sale; overdue rate | Margin added to the indicator rate | Westpac Group brand; same structure as St.George and Bank of Melbourne |
| IMB Bank | Variable business loan rates listed by security type | Built into the listed rate by security | Mutual; residentially secured business loans priced lowest |
| CommBank | Starting rates for secured and unsecured business loans and overdrafts (see the table above) | Rate on the file above the starting rate | Unsecured overdraft $2,000 to $250,000; one-off establishment fee; 1.70% p.a. line fee |
| ING (commercial property) | Fixed and variable, rate on application | Not published | Fixed 1 to 5 years reverting to variable; Priority Commercial Loans $500,000 to $8M |

What is a good rate, by product?
Because the rate follows the security, the honest answer is a range per product rather than a single number. In order of published cost, lowest first:
- Property-secured business loans. Closest to home loan pricing: on 10 October 2026 CommBank published secured business loans from 7.54% p.a. and Westpac from 8.16% p.a.
- Commercial property loans. Priced on the LVR, the property type and the documentation: Emu Money's guide puts the saving at 0.25% to 0.75% per 10% of LVR and the gap within one lender at 2% to 3%. See the commercial property loans guide.
- Vehicle and equipment finance. Fixed for the term and secured by the asset; CommBank publishes up to 0.50% p.a. off for green vehicles and equipment, which shows how much the asset type moves the rate.
- Secured overdrafts and lines of credit. Base rate plus a margin, plus a line fee on the limit: Westpac overdrafts from 8.36% p.a. with a 1.20% p.a. line fee, CommBank secured overdrafts from 9.00% p.a. with 1.70% p.a.
- Unsecured term loans and fintech cash flow loans. The widest spread, priced on trading history and bank statements rather than security: 12.95% p.a. fixed (NAB QuickBiz) and 13.09% p.a. (CommBank) at the banks, and higher at the online lenders. See unsecured business loans.
What moves your rate up or down?
| Factor | Effect on the margin | Published evidence |
|---|---|---|
| Security offered | Largest single lever: property, then vehicles and equipment, then unsecured | CommBank: secured business loans from 7.54% p.a. against unsecured from 13.09% p.a. (10 October 2026); Westpac: rates vary with the type of security |
| Loan-to-value ratio | Lower LVR, lower margin | Emu Money: 0.25% to 0.75% saved per 10% reduction in LVR |
| Trading history and financials | Two years of clean financials and a clear ATO position price best; under 12 months trading narrows the field | CommBank overdraft page notes conditions for businesses trading under 12 months; NAB QuickBiz requires 12 months under the current ABN |
| Loan size and term | Larger loans on longer terms access bank bill pricing; short unsecured loans carry the highest rates | NAB: bank bill pricing periods; terms 30 days to 15 years |
| Asset type | Green assets discounted; specialised property loaded | CommBank up to 0.50% p.a. off green vehicles and equipment; Emu Money on specialised property risk |
| Cash rate and funding costs | Moves the base, not the margin | Cash rate target raised to 4.60% effective 30 September 2026; CommBank and Westpac's published business rates rose 0.25 points by 9 October |
Comparing offers without a comparison rate
Ask each lender for four numbers: the rate and whether it is fixed, variable or bank bill; the establishment fee; the ongoing line, service or annual fee; and the cost of repaying early.
Put them into the business loan calculator over the period you expect to hold the loan, not the contract term, and compare the total in dollars. A facility with a lower rate and a 1.70% line fee on a limit you rarely use can cost more than a slightly dearer loan with no line fee.
A broker does this across lenders in one pass and negotiates the margin, which is the only part of the rate that moves for you. See what a business loan broker does.
