What is a business overdraft
A business overdraft is a revolving line of credit attached to your business transaction account. Your lender approves a set limit. You can then draw funds below zero, up to that limit, whenever you need to.
When money comes into your account, it automatically reduces the overdrawn balance. You only pay interest on what you actually use, not the full approved limit.
How does a business overdraft work
Once approved, the facility links directly to your business transaction account. You draw funds as needed, with no fixed repayments. As deposits hit your account, the balance reduces, and your available credit restores automatically.
Interest is calculated daily on your overdrawn balance and charged monthly. So, if your limit is AUD $50,000 but you only draw AUD $10,000, you pay interest on AUD $10,000 only.
What can you use a business overdraft for
A business overdraft is designed for short-term working capital needs, not long-term funding. Common uses include:
- Covering employee wages when a client payment is delayed
- Paying supplier invoices before customer funds arrive
- Handling unexpected operating expenses
- Managing seasonal cash flow dips
- Taking advantage of a time-sensitive bulk stock purchase
Secured vs unsecured business overdraft
A secured business overdraft requires an asset as security, typically residential, commercial, or rural property. Lower lender risk generally means a lower interest rate, though approval takes longer due to asset valuation.
An unsecured business overdraft doesn't require a specific asset. Lenders assess your financial history, cash flow, and directors' credit profiles.
Approval is faster, but rates are higher. A personal guarantee from directors is often still required. For most small businesses needing funds under AUD $250,000, an unsecured business overdraft is the more practical starting point.
Business overdraft rates and fees
There are three main charges to know.
The interest rate is charged daily on your drawn balance and applied monthly. Secured overdraft rates can start from around 8.50% p.a., while unsecured rates typically range from 14.55% to 25% p.a.
The establishment fee is a one-off setup cost, confirmed in your Letter of Offer before you sign. It typically ranges from 0.75% to 3% of the approved limit.
The line fee is an ongoing charge on your approved limit or outstanding balance. It's calculated daily but charged monthly, quarterly, or semi-annually. You pay it even when you're not drawing on the facility.
The ATO permits full deductibility of overdraft interest when funds are used for income-producing purposes. Confirm this with your accountant.
Eligibility requirements
Eligibility criteria vary by lender, but most look for:
- An active ABN registered in Australia
- A minimum trading period, often 6 months to 2 years
- Evidence of consistent revenue and healthy cash flow
- Acceptable credit history for the business and its directors
- For secured facilities, suitable property or business assets as collateral
- A personal guarantee from directors for corporate borrowers
ASIC-regulated lenders must assess your ability to repay and provide clear disclosure of all fees and terms.
Documents required to apply
Most lenders will ask for a combination of the following:
- Latest annual financial statements or business tax return
- 12 months of Business Activity Statements (BAS) from the ATO
- Six to 12 months of business bank statements
- Proof of identity, such as a driver's licence or passport
- ASIC registration details, including your ABN and ACN
- For secured facilities, documentation relating to the proposed security
Some non-bank lenders require only 6 months of bank statements for an unsecured overdraft decision.
How to apply for a business overdraft
Most lenders now offer online applications that take 15 to 20 minutes. Ensure your books are up to date, gather your documents, and complete the application. Some approvals are instant.
If approved, your Letter of Offer confirms the limit, interest rate, establishment fee, and line fee. The facility is then available immediately.
Pros and cons
Like any financial product, a business overdraft has advantages and drawbacks worth weighing up.
Pros:
- Interest is only charged on what you draw, not the full limit
- Funds are available on demand with no need to reapply
- Flexible repayment with no fixed schedule
- Quick approval, especially for unsecured facilities
Cons:
- Interest rates are higher than most term loans
- Line fees apply even when you're not using the overdraft
- Not suitable for long-term or large capital needs
- Directors may be personally liable through personal guarantees
Business overdraft vs business loan: What is the difference
A business overdraft has no fixed term or set repayments. It suits ongoing short-term working capital needs. A business loan provides a lump sum repaid over a fixed term, better suited to purchases like equipment or fit-outs.
If you have a recurring cash flow gap, an overdraft offers flexibility. If you're funding a one-time investment, a loan is usually more cost effective.
FAQs
Here are answers to some common questions about business overdrafts in Australia.

Can I get a business overdraft without security?
Yes, an unsecured business overdraft requires no specific asset as collateral. However, lenders may still require a personal guarantee from directors.
How is interest calculated on a business overdraft?
Interest is calculated daily on your overdrawn balance and charged monthly. You only pay for what you use.
What is the difference between a secured and an unsecured business overdraft?
A secured business overdraft is backed by property, offering lower rates. An unsecured business overdraft relies on cash flow and credit profile, with faster approval but higher rates.
