Business line of credit in Australia

Draw it, repay it, draw it again

A business line of credit is an approved limit you draw against, repay and draw again, paying interest only on what is outstanding. The banks sell it as an overdraft with a line fee on the whole limit; the online lenders sell it as a revolving facility and charge on what is drawn. Published limits run from $2,000 at CommBank to $2M at Shift.

How much interest will I pay on a $10,000 line of credit?

About $1,550 a year, or roughly $129 a month, if the full $10,000 stays drawn for a year at Lumi's published starting rate of 15.5% APR, which carries no ongoing fees. At a bank the rate can be lower but a line fee is charged on the whole limit: Westpac publishes overdraft rates from 8.11% p.a. (about $811 a year) plus a 1.20% p.a. line fee ($120), and CommBank's unsecured overdraft starts at 14.80% p.a. plus a 1.70% p.a. line fee. Draw less, or repay sooner, and the interest falls in proportion, because you pay only on what is outstanding.

How does a business line of credit work?

A business line of credit gives your business a pre-approved limit you can draw on at any time without reapplying. Unlike a term loan, which pays a lump sum upfront, it acts as a pool of funds you use only when needed.

Interest starts on the drawn amount from the day you draw it. As you repay, the available credit replenishes, ready to be drawn again, for as long as the facility runs.

For example, with a $200,000 line of credit you might draw $50,000 to buy stock and pay interest only on that $50,000. When the stock sells and you repay it, the full $200,000 is available again for the next need.

Which lenders offer a business line of credit, and on what terms?

The same product goes by two names: overdraft at the banks, line of credit at the online lenders. The fee structure is the real difference. Checked against each lender's published product page on 20 September 2026, with the Westpac, CommBank and Lumi fees and rates re-checked on 30 September 2026. Terms change without notice; confirm the current position with the lender or your broker before relying on it. Where a lender does not publish a figure the cell says so.

What are the benefits of a line of credit?

Flexibility. A term loan charges interest on the whole balance whether you need the money or not; a line of credit charges only on what you use, which makes it cheaper for funding needs that come and go.

It also handles uncertainty. Rather than guessing how much you will need and for how long, you set a limit and draw as circumstances dictate, without the delay of a new application each time.

For a growing business the limit can grow too: lenders review facilities, usually annually, and can raise the limit in line with revenue.

What do businesses use a line of credit for?

The most common uses include:

  • Working capital management: Smoothing cash flow between customer payments and business expenses
  • Stock and inventory: Purchasing stock ahead of busy periods and repaying as it sells
  • Seasonal businesses: Funding operations during quiet seasons and repaying during peak trading
  • Opportunity funding: Having capital ready to act on time-sensitive business opportunities
  • Project bridging: Covering costs at the start of projects before progress payments arrive
  • Emergency buffer: Maintaining access to funds for unexpected expenses or opportunities

Who is eligible, and how do you apply?

What lenders look for

Typically a registered ABN active for at least 12 months (Lumi publishes six), consistent monthly revenue, a clean personal and business credit history, and business bank statements showing healthy cash flow. Secured facilities also need property or other assets as collateral.

How the application runs

Enquiring through Your Finance Guide starts with a short online form. If you ask for a broker, a licensed broker who meets our criteria asks for business bank statements and basic identification and matches you with a suitable lender. Lumi publishes approval and funding on the same business day for its line of credit; secured bank facilities take longer because the property has to be valued.

Sizing the limit

Size the limit to your largest realistic gap, not the most you can get. At the banks the line fee is charged on the whole limit, so an oversized facility costs money every month even if you never draw it. If the balance never comes back to zero, a term loan is usually the cheaper home for that debt.

Business line of credit FAQs

How much interest will I pay on a $10,000 line of credit?
About $1,550 a year, or roughly $129 a month, if the full $10,000 stays drawn for a year at Lumi's published starting rate of 15.5% APR, which carries no ongoing fees. At a bank the rate can be lower but a line fee is charged on the whole limit: Westpac publishes overdraft rates from 8.11% p.a. (about $811 a year) plus a 1.20% p.a. line fee ($120), and CommBank's unsecured overdraft starts at 14.80% p.a. plus a 1.70% p.a. line fee. Draw less, or repay sooner, and the interest falls in proportion, because you pay only on what is outstanding.
What is the difference between a line of credit and an overdraft?
Mostly the name. A bank overdraft is a line of credit attached to your transaction account: CommBank publishes unsecured limits from $2,000 to $250,000 and NAB from $20,000. The banks charge a line fee on the whole approved limit whether you use it or not (Westpac publishes 1.20% p.a.) plus interest on the drawn balance. Online lenders such as Lumi and Prospa charge on what is drawn, with Prospa adding a weekly service fee and Shift an annual fee.
How much does a business line of credit cost if I do not use it?
At the banks, the line fee: Westpac publishes 1.20% p.a. on the total limit, so a $100,000 overdraft costs about $1,200 a year undrawn, and CommBank publishes 1.70% p.a. Shift charges $495 or $795 a year depending on the limit. Lumi publishes no ongoing fees and interest only on what you use. Compare the undrawn cost first if the facility is a buffer rather than a working balance.
Can I get a business line of credit for $100,000?
Yes, within most lenders' published limits. Lumi lends up to $1M to businesses with six months of trading and $50,000 of annual revenue, Prospa up to $500,000 with no upfront security to $150,000, and CommBank publishes unsecured overdraft limits to $250,000. At that size the lender will look closely at your bank statements, and a bank may ask for security to offer its lower secured rate.
What is a business line of credit?
A business line of credit is a flexible revolving finance facility that gives you access to an approved credit limit. You can draw down funds as needed and repay at your own pace, only paying interest on the amount currently drawn. Once repaid, the funds become available again without reapplying.
How is a line of credit different from a term loan?
A term loan provides a lump sum with fixed repayments over a set period. A line of credit lets you draw and repay repeatedly, providing ongoing access to funds. Term loans suit one-off expenses, while lines of credit suit ongoing or variable funding needs.
What are the disadvantages of a business line of credit?
Three main ones. At the banks the line fee is charged on the whole limit whether you use it or not; the rate is usually variable, so the cost moves with the market; and a facility with no set repayments makes it easy to leave a balance drawn permanently, where a term loan would be cheaper. Bank overdrafts can also be reviewed or reduced by the lender.
What credit limit can I get?
Business lines of credit range from $10,000 to $1 million or more. Your limit depends on your business revenue, trading history, credit profile, and whether you provide security. Unsecured lines are typically available up to $250,000.
Do I need minimum monthly repayments?
Most lines of credit require at least interest-only payments on the drawn amount each month. Some facilities allow interest to capitalise in the short term. The key difference from a term loan is that there is no mandatory principal repayment schedule, you control when and how much you repay.
Can I increase my line of credit limit?
Yes. Most lenders will review your facility periodically (usually annually) and may offer limit increases based on your business performance and account conduct. You can also request a review at any time if your needs have changed.
What can I use a business line of credit for?
A line of credit can be used for any legitimate business purpose including working capital, stock purchases, managing seasonal cash flow, bridging payment gaps, marketing spend, covering unexpected costs, and taking advantage of business opportunities.
