What Is a Business Line of Credit and How Does It Work?
Business Line of Credit
Australian small business · Cashflow · Revolving credit
A small business line of credit is revolving cashflow funding for Australian businesses: draw up to an approved limit, repay, and redraw without a new application. This guide answers how it works, rates and fees, line of credit vs overdraft, secured vs unsecured options, eligibility, limits, documents, approval timing and the risks to check before signing.
Quick Answer
A small business line of credit is a revolving facility that lets an Australian business draw, repay and redraw funds up to an approved limit. Interest is usually charged only on the drawn balance, while establishment, line or unused-limit fees may still apply.
What is a small business line of credit?
A small business line of credit is a revolving finance facility that lets a business draw funds up to an approved limit, repay part or all of the balance, and redraw the available amount without making a new application each time. Interest is generally charged on the amount drawn rather than the full limit.
In Australia, the terms business line of credit and business overdraft are often used for facilities that solve the same cashflow problem. The usual distinction is structural: an overdraft is commonly attached to the trading account, while a line of credit is commonly a separate account or facility. The Australian Government's business glossary defines a line of credit as an agreement that lets a borrower withdraw money up to an approved limit. Our business line of credit and overdraft page explains the options we arrange, while the line of credit glossary entry gives the one-line definition.
How does a business line of credit work?
A lender approves a credit limit, the business draws only what it needs, and repayments restore the available balance so it can be used again. The facility is revolving, which is what separates it from a one-off business loan.
- A limit is approved. The lender sets the maximum available amount and the conditions for using it.
- The business draws funds. Money is accessed only when a short-term need arises.
- Interest and fees are charged. Interest is generally based on the drawn balance, while facility fees may be based on the approved limit.
- Repayments restore availability. As principal is repaid, the same amount becomes available to draw again, subject to the facility terms.
What can a small business line of credit be used for?
A small business line of credit is best suited to short-term or recurring cashflow needs such as stock purchases, supplier bills, wages, BAS timing, seasonal gaps, urgent repairs or delayed customer payments. It is usually less suitable for a long-life asset or a permanent funding shortfall, where a term loan, chattel mortgage or another fixed facility may match the cost better.
Do business lines of credit have fixed repayments?
Not always. Some facilities require scheduled principal and interest repayments, some require interest plus a minimum principal amount, and others allow more flexible reductions while the line remains within its terms. The repayment frequency, review date, expiry date and any requirement to clear the balance should be checked in the offer before acceptance.
Business line of credit vs business overdraft: what is the difference?
A business overdraft is an account-linked form of revolving credit, while the broader term business line of credit can also describe a separate facility with its own draw, repayment and review rules. Both can fund recurring cashflow gaps, but the operating mechanics are different.
| Feature | Business line of credit | Business overdraft |
|---|---|---|
| Set-up | Usually a standalone revolving facility with its own account, portal or limit. | Usually attached directly to the business transaction account. |
| Access | Transfer or draw from the facility when funds are needed. | The transaction account moves below zero, up to the approved limit. |
| Repayment effect | Principal repayments restore the amount available to redraw. | Deposits into the operating account automatically reduce the debit balance. |
| Fee focus | Check facility, draw, unused-limit, establishment and default fees. | Check debit interest, line fees, account fees and excess-drawing costs. |
| Common fit | A separate cashflow reserve with controlled draw-and-repay cycles. | A short everyday buffer inside the account the business already operates. |
The product label is less important than the contract. Compare access, total fees, security, repayment requirements, review rights and whether the facility can be reduced or called in. For the account-linked mechanics, read the complete business overdraft guide.
Line of credit, term loan, invoice finance or business credit card: which cashflow tool?
Use a line of credit for a recurring or unpredictable gap, a term loan for a known one-off cost, invoice finance for cash tied up in eligible business invoices, and a business credit card for smaller card-based purchases. Matching the product to the shape of the expense is usually more important than choosing the fastest approval.
| Funding option | How it works | Usually best suited to |
|---|---|---|
| Line of credit or overdraft | Revolving limit that can be drawn, repaid and redrawn; interest generally applies to the drawn balance | Ongoing or unpredictable short-term cashflow gaps |
| Working capital loan | A lump sum repaid over an agreed term | A known cost that needs a defined repayment schedule |
| Invoice finance | An advance against eligible unpaid business-to-business invoices | Cashflow delayed by slow-paying business customers |
| Business credit card | A revolving card limit that may offer interest-free days, after which card interest and fees can apply | Smaller everyday purchases and a short payment float |
| Chattel mortgage or asset finance | Funding attached to a particular vehicle or item of equipment | A specific business asset with a useful life longer than a cashflow cycle |
| Secured business loan | A larger fixed facility secured by property or another asset | A substantial planned investment that is not expected to repay within a short cycle |
The practical rule is simple: a revolving need usually wants revolving funding, a fixed cost usually wants a fixed loan, and a receivables delay may be better matched to invoice finance.
Secured vs unsecured business line of credit
An unsecured business line of credit is assessed mainly against the business's revenue, trading history, credit profile and banking conduct. A secured line of credit also uses property or another acceptable asset to reduce the lender's risk, which can support a larger limit or lower pricing but adds security documents and, in many cases, valuation work.
| Factor | Unsecured line of credit | Secured line of credit |
|---|---|---|
| What supports the facility | Business revenue, credit profile and banking conduct, often with a general security interest | Property equity or another acceptable registered asset in addition to the business position |
| Limit tendency | Usually lower because no property is supporting the debt | Can be higher where the security and serviceability support it |
| Pricing tendency | Usually higher to reflect the additional lender risk | Can be lower because the lender has asset security |
| Speed and documents | Often faster and may not require a valuation | Often slower because security checks, valuation and legal steps may apply |
| Main trade-off | Speed and simplicity in exchange for a smaller or more expensive facility | Potentially more capacity or sharper pricing in exchange for security risk and more documentation |
Security should not be offered merely to obtain a larger limit. The business needs a repayment plan that works without relying on the secured property being sold.
What are business line of credit rates, fees and costs?
Business line of credit interest is generally charged on the amount drawn, not the full approved limit. There is no single standard rate in Australia: pricing depends on whether the facility is secured, the business's revenue and credit profile, document quality, trading history, industry, repayment structure and the lender's fee model.
What is a normal business line of credit interest rate?
There is no reliable single “normal” rate because two facilities with the same limit can have different security, repayment terms and fees. Secured facilities generally price below comparable unsecured facilities, while weaker credit, short trading history or irregular banking conduct can increase the cost. Compare the annualised interest cost and every compulsory fee in dollars, not only the advertised rate.
| Cost component | How it may be charged | What to check |
|---|---|---|
| Interest | Usually calculated on the drawn balance and may be fixed or variable | The annual rate, calculation method, repayment frequency and whether default interest applies |
| Establishment or application fee | A one-off fixed fee or a percentage of the approved limit | The dollar amount payable even if little of the limit is used |
| Line or facility fee | Monthly, quarterly or annual; fixed or based on the approved limit | Whether the fee continues while the facility is undrawn |
| Draw fee | A charge each time funds are accessed under some products | Whether frequent small drawdowns make the facility expensive |
| Late or default charges | Triggered by missed payments, limit breaches or other defaults | The events that trigger the fee and the higher default rate, if any |
| Security costs | Valuation, legal, registration or discharge costs on a secured facility | Which third-party costs are payable upfront and again at review or exit |
How is business line of credit interest calculated?
A simple daily-interest estimate is the drawn balance multiplied by the annual interest rate, multiplied by the number of days drawn, divided by 365. The actual contract may use a different day count, compounding method, periodic fee or repayment structure, so the lender's calculation method controls.
What is the monthly payment on a $50,000 business line of credit?
There is no standard monthly payment on a $50,000 business line of credit because repayment structures vary. A lender may require monthly interest plus a minimum principal amount, a fixed weekly or monthly repayment for each draw, or flexible principal reductions subject to the facility terms. Using the illustrative 15% rate above, 30 days of interest on a fully drawn $50,000 balance is about $616 before fees, but the required payment could be higher once principal and product fees are included.
Indicative, from broking experience
Indicative only, drawn from Switchboard line of credit and overdraft broking as at July 2026. Not a quote, not an offer, and not a rate or limit you will receive. Every facility is priced and assessed on its security, documents, banking conduct and individual facts.
- Cost basis: interest is commonly charged on the drawn balance, while an establishment, facility or line fee may still apply to the approved limit.
- Rate posture: pricing varies widely and is commonly higher for an unsecured facility than a comparable property-secured bank overdraft, but lower than some short-term unsecured cashflow products. This is not a rate you will receive.
- Approval timing: a straightforward low-doc file may receive conditional approval within about 24 to 48 hours once recent BAS and three to six months of business bank statements are complete.
- Indicative limit range: many non-bank revolving facilities we see fall around $20,000 to $500,000, while stronger turnover or acceptable property security can support more. This is not a limit you will receive.
- Common decline drivers: unmanaged tax arrears without a payment plan, repeated dishonours, sustained overdrawn conduct, very short trading history, or a requested limit that is not supported by turnover.

What do current Australian business line of credit fees and limits look like?
There is no market-wide standard, but a dated lender example shows how fees can scale with the approved limit. As verified on 7 July 2026, Suncorp Bank's published business line of credit page listed the following facility fees. These are one bank's advertised product settings, not a market average, Switchboard quote or rate an applicant will receive.
| Published credit-limit band | Published facility fee | Important context |
|---|---|---|
| Up to $100,000 | $150 per quarter | Fee applies to the approved limit under this product, not only the amount drawn. |
| $100,001 to $250,000 | $300 per quarter | Interest is separately charged on the amount used. |
| $250,001 to $500,000 | $500 per quarter | Property or acceptable business-asset security and a fully documented application are stated requirements. |
| Above $500,000 | 0.75% p.a. of the credit limit, or as set out in the offer | Terms, pricing and eligibility can change and must be checked directly with the lender. |

Is business line of credit interest tax deductible?
Interest may be deductible to the extent the borrowed money is used to earn assessable business income, while private or mixed use may require the interest and fees to be apportioned. The tax outcome follows how each draw is used, not merely the facility's business label. Keep draw-level records and obtain advice from a registered tax agent because establishment fees and other borrowing costs can have different treatment from ordinary interest.
Tax guidance: Australian Taxation Office, interest expenses.
For wider market context only, Australian business credit grew 9.9% over the year to May 2026 (RBA Financial Aggregates, seasonally adjusted). That is a growth rate for business credit, not a line of credit interest rate and not a guide to the price of an individual facility.
How is a business line of credit limit set?
A lender sets the credit limit by estimating how much revolving debt the business can use and repay safely. Monthly turnover is important, but it is considered alongside average bank balances, cashflow volatility, existing debts, credit history, trading time, industry risk and any security offered.
How much can you borrow with a business line of credit?
There is no universal maximum. In Switchboard's non-bank revolving-credit enquiries, many requested or approved limits fall around $20,000 to $500,000, while stronger turnover, serviceability or acceptable property security can support more. Current bank products can also extend above $500,000, but the useful limit is the amount the business can cycle down from normal cashflow rather than the largest amount available.
The three inputs that most often change the result are:
- Turnover and cash conversion. Stable revenue and a clear reason for the temporary gap support a larger revolving limit.
- Banking conduct and existing debt. Repeated dishonours, persistent overdrawing or heavy current commitments can reduce the limit or stop approval.
- Security. An unsecured limit is mainly tied to the business position; acceptable property equity can support more capacity but also puts that asset at risk.
The indicative broker range in the cost section shows where many non-bank facilities can sit, but it is not a borrowing entitlement. A useful limit is one the business can regularly pay down, not merely the largest amount available.
Who qualifies for a small business line of credit?
Eligibility usually depends on an active ABN, established business revenue, enough trading history to show a pattern, manageable credit and clean enough bank conduct to support repayment. Some specialist lenders can assess recent BAS and three to six months of business bank statements instead of a full financial pack, but requirements vary and low-doc does not mean no-doc.
Usually a stronger fit
A line of credit is usually a stronger fit when revenue is established, the cashflow need is short term and the business has a clear way to reduce the balance.
- Consistent revenue paid through a business account
- A short-term or recurring cashflow purpose with a clear repayment source
- Manageable existing debts and limited recent dishonours
- Enough trading history for the lender to see a pattern
- Property equity available where a larger secured facility is needed
Often harder to approve
Approval is often harder where there is little trading history, weak bank conduct, unresolved arrears or no credible repayment source.
- A pre-revenue startup with no trading history
- Ongoing losses with no clear path to reducing the balance
- Recent unmanaged tax arrears or repeated dishonours
- A requested limit far above the business's revenue and bank conduct
- A long-term asset purchase better matched to fixed asset finance
Can a sole trader get a business line of credit?
Yes. A sole trader can apply for a business line of credit using an active ABN, but the lender may assess both the business cashflow and the owner's personal credit position because the business and individual are not separate legal entities. Eligibility still depends on trading history, revenue, bank conduct, existing debts, tax position and a credible repayment source.
Is it hard to get a business line of credit?
It is usually easier for an established business with consistent deposits, manageable debts and clean recent bank conduct than for a startup or a business with repeated dishonours. Lenders commonly assess trading history, revenue, repayment capacity, credit, tax position, existing facilities and any security. A sensible limit tied to a documented cashflow gap is generally easier to support than a request for the largest possible amount.
Can a startup or new business get a business line of credit?
A pre-revenue startup will usually struggle because there is no operating cashflow for a lender to assess. A newer trading business may have options once it can show consistent sales and recent bank statements, with some lenders considering files from around six to twelve months of trading. The minimum varies by lender and stronger security does not replace the need for a credible repayment source.
Can you get a business line of credit with bad credit?
It can be possible, but approval, limit and price depend on what the adverse credit was, how recent it is, whether it has been resolved and what the current bank statements show. A minor older issue is different from active defaults, repeated dishonours or unpaid tax debt. A broker should assess the likely fit before a formal credit enquiry is authorised.

How to get a business line of credit
To get a business line of credit, define the cashflow gap and required limit, compare the complete cost and repayment terms, then give the lender enough current information to verify revenue, banking conduct and the repayment source. A clean, complete file generally moves faster than a larger but poorly explained request.
What documents are needed for a business line of credit?
Document requirements vary, but a small business is commonly asked for:
- Proof of identity, ABN and business structure
- Three to six months of business bank statements
- Recent BAS or other current turnover evidence
- Existing debt details and an explanation of the funding purpose
- Financial statements or tax returns where the lender or deal requires them
- Property details, rates notice and valuation information for a secured facility
What is the business line of credit approval process?
The approval process usually moves from sizing the need to comparing structures, providing documents, credit assessment, reviewing the offer and activating the facility.
- Set the purpose, likely peak draw and repayment source.
- Compare secured and unsecured structures, rates, fees, term and review rights.
- Provide the lender with current documents and authority to assess the file.
- Review the offer, including the total dollar cost, minimum repayments, security and events of default.
- Activate the facility and use it only for the short-term purpose it was designed to cover.
Does applying for a business line of credit affect your credit file?
A formal lender application can create a credit enquiry and the facility may appear in commercial or personal credit reporting, depending on the borrower and guarantee structure. A preliminary eligibility discussion may not require a recorded enquiry, so ask what check will occur before consent is given. A targeted application is generally preferable to sending the same file to multiple lenders without a clear strategy.
Can you get a business line of credit without a credit check?
A broker may be able to discuss likely eligibility without recording a formal credit enquiry, but a lender will normally complete identity, fraud, credit and repayment-capacity checks before approving a facility. Claims of guaranteed business credit with no assessment should be treated cautiously. Ask whether the initial check is a soft eligibility review or a formal enquiry before giving consent.
Cashflow timing has become more important since Payday Super commenced on 1 July 2026. Employers now pay super with wages and contributions must reach the fund within seven business days, rather than being paid quarterly. That does not make borrowing appropriate by itself, but it is one example of why a recurring cash buffer needs to be sized against the business's real payment cycle. Ready to discuss a structure? Use the line of credit and overdraft page or check eligibility for an indicative review.
Is a business line of credit a good idea, and what are the risks?
A business line of credit can be a good idea when it covers a temporary, recurring cashflow gap and the business expects to reduce the balance as revenue arrives. It is usually a poor fit when the balance funds permanent losses, a long-life asset or expenses with no identifiable repayment source.
When it can work well
It can work well when the balance rises for a temporary need and falls again as revenue is received.
- Smoothing seasonal or lumpy cashflow
- Covering a short supplier, payroll or BAS timing gap
- Holding an emergency buffer without drawing the full limit
- Buying stock that converts back to cash within a known cycle
- Covering the wait for customer payments where invoice finance is not the better fit
Warning signs
The facility is a warning sign when the balance stays near the limit, funds recurring losses or cannot be reduced from normal trading cashflow.
- The balance remains near the limit and never materially reduces
- Borrowing is covering ongoing trading losses
- A fixed asset is being funded with short-term revolving debt
- Fees continue on an unused limit that the business no longer needs
- The contract allows review or repayment at a time the business cannot meet
Can a lender reduce or cancel a business line of credit?
Yes, if the contract permits it. A lender may review, reduce, suspend or cancel a facility after an expiry date, covenant breach, missed payment, material deterioration or another event set out in the agreement. Check whether the line is ongoing or fixed-term, whether the lender can demand repayment, and what happens to the balance if redraw is stopped.
A useful line of credit should move up and down with the business's cash cycle. If it only moves upward, the problem is no longer a timing gap and the funding structure should be reviewed.
A small business line of credit is revolving funding that can be drawn, repaid and redrawn up to an approved limit. Interest is generally charged on the drawn balance, but establishment, facility, unused-limit, draw and security costs can materially change the total price. It is most useful for short-term cashflow needs that reverse when revenue arrives, and it can be secured or unsecured depending on the limit, pricing and risk trade-off.
Best test: can the business identify when and how the drawn balance will be reduced? If not, a revolving line may be masking a permanent funding problem rather than solving a timing gap.Frequently asked questions
A business line of credit is a revolving facility that lets a business draw, repay and redraw funds up to an approved limit without making a new application for every draw. Interest is generally charged on the amount used rather than the full limit, while facility or line fees may still apply.
They perform a similar revolving cashflow function, but an overdraft is usually attached to the transaction account while a line of credit is commonly a separate facility. The business overdraft guide explains the account-linked structure, line fees, excess drawings and review risk.
The lender approves a maximum limit, the business draws only what it needs, and principal repayments restore the amount available for future use. Interest is generally calculated on the drawn balance, although facility or draw fees and minimum repayments may also apply.
Interest is generally charged on the amount drawn rather than the full approved limit. Total cost can also include establishment, line, facility, draw, default, valuation and legal fees, so compare the annual dollar cost and repayment structure rather than only the headline rate.
Yes. An established business with sufficient revenue, manageable credit and acceptable bank conduct may qualify without property security. Unsecured facilities can be faster and simpler, but limits may be lower and pricing higher than a comparable secured facility, and a director guarantee may still be required.
The limit is usually based on turnover, cashflow volatility, average bank balances, trading history, existing debt, credit profile, the purpose of the facility and any security. Based on Switchboard broking experience as at July 2026, many non-bank facilities we see fall around $20,000 to $500,000, but this is indicative only and not a limit an applicant will receive.
ABN holders across industries can be eligible when they have enough trading history, consistent revenue, acceptable recent bank conduct and a credible repayment source. Tradies, transport operators, cafes and other self-employed businesses are assessed on their actual cashflow, debts, credit, tax position and requested limit rather than their industry label alone.
A straightforward low-doc application may receive conditional approval in about 24 to 48 hours once the required BAS and recent business bank statements are complete. That timing is indicative only, based on Switchboard broking experience as at July 2026, and can be longer where security, valuation, financial statements or complex credit issues are involved.
A line of credit usually suits recurring or uncertain cashflow gaps because repaid principal can be redrawn. A working capital term loan usually suits a known one-off amount with scheduled repayments. Compare the total cost, repayment pressure, draw flexibility and whether the balance is expected to cycle down.
It can be useful for a temporary cashflow gap with a clear repayment source, but it is risky when used for permanent losses or long-life assets. Business-purpose credit generally has fewer statutory protections than consumer credit, and access to AFCA depends on the lender and applicable small-business rules. Check review, cancellation, default and guarantee terms before signing.
