A business overdraft is a revolving line of credit that gives Australian businesses access to funds up to an approved limit. You draw funds when you need them and repay when cash flows into your business account. Interest is charged daily only on the amount you have drawn - not your full approved limit. There is no loan-style fixed repayment schedule (many non-bank lenders set minimum weekly repayments), no lump sum obligations and no need to reapply each time you need to draw.
Business overdrafts are the most flexible working capital tool available to Australian SMEs. They sit in the background of your business - costing very little when unused (just the annual line fee) and immediately accessible when cash flow gaps arise. Whether you need to cover wages before a client pays, fund materials for a large job, or bridge a seasonal revenue dip, a business overdraft is the fastest and most efficient solution.
In Australia, business overdraft and business line of credit are terms used interchangeably. Both describe the same revolving credit product. Banks call it an overdraft; non-bank lenders typically call it a line of credit or facility. The mechanics are identical.

Understanding the mechanics of a business overdraft helps you use one effectively and avoid unnecessary costs.
Unlike a term loan where you receive a lump sum and make fixed repayments over a set period, a business overdraft operates as a revolving facility. Your approved limit is always available. You draw what you need, when you need it. You repay as cash comes in. The repaid amount is immediately available to draw again. This cycle continues for the life of the facility - typically reviewed annually.
Business overdraft interest in Australia is calculated daily on the outstanding drawn balance and charged monthly. The formula is straightforward:
Daily interest = (Amount drawn × Annual rate) ÷ 365
| Amount drawn | Rate | Days drawn | Interest cost |
|---|---|---|---|
| $10,000 | 20% p.a. | 30 days | $164 |
| $30,000 | 20% p.a. | 30 days | $493 |
| $50,000 | 20% p.a. | 30 days | $822 |
| $100,000 | 20% p.a. | 30 days | $1,644 |
| $200,000 | 20% p.a. | 30 days | $3,288 |
Most lenders charge an annual line fee on your approved limit - regardless of whether you use the facility. This is typically 0.5-2% per annum of the approved limit. On a $100,000 facility at 1% p.a., the line fee is $1,000 per year - approximately $83 per month whether you draw on the facility or not.
A one-off fee charged when the facility is first approved. Typically 0.75-3% of the approved limit. On a $100,000 facility at 1.5%, this is $1,500 - charged once at setup.
Key advantage: You only pay for what you use. A $100,000 business overdraft sitting completely unused costs approximately $1,000-$2,000 per year in line fees - acting as financial insurance that's there when you need it.
Non-bank lenders have made business overdrafts far more accessible than the banks. The standard eligibility criteria for a non-bank business overdraft in Australia are:
| Criteria | Non-bank lenders | Major banks |
|---|---|---|
| Trading history | 6 months minimum | 2+ years typically |
| Monthly revenue | $6,000+ per month | Often $20,000+ |
| Credit score | Equifax 550+ | 650+ typically |
| Tax returns | Not required | 2 years required |
| Property security | Not required under $150K | Often required |
| ATO debt | OK with payment plan | Usually declined |
| Financial statements | Not required | Required |
| Documents needed | Bank statements, ABN, licence | Full financial package |
| Approval time | 1-24 hours | 2-8 weeks |
For non-bank business overdrafts, your 6 months of bank statements are the core assessment document. Lenders analyse:
Business overdraft limits in Australia are primarily determined by your average monthly revenue. Most non-bank lenders will approve up to 1-1.5x your average monthly revenue based on your last 6 months of bank statements.
| Monthly revenue | Estimated overdraft limit | Maximum possible |
|---|---|---|
| $6,000-$10,000 | $6,000-$12,000 | $15,000 |
| $10,000-$25,000 | $10,000-$30,000 | $37,500 |
| $25,000-$50,000 | $25,000-$60,000 | $75,000 |
| $50,000-$100,000 | $50,000-$120,000 | $150,000 |
| $100,000-$200,000 | $100,000-$240,000 | $300,000 |
| $200,000-$350,000 | $200,000-$420,000 | $500,000 |

Business overdraft interest rates in Australia vary significantly by lender type and business profile. Understanding the full cost picture - not just the headline rate - is critical before committing to any facility.
| Lender type | Interest rate | Line fee | Who qualifies |
|---|---|---|---|
| Major banks | 8-15% p.a. | 1-2% p.a. | 2+ years, full financials, often property |
| Non-bank lenders | 14-30% p.a. | 0.5-2% p.a. | 6+ months, bank statements only |
| OverdraftMe panel | From 14.55% p.a. | 0.5-2% p.a. | 6+ months, $6,000+/month, Equifax 550+ |
| Specialist lenders | 25-40% p.a. | Varies | Poor credit, short history |
The most important thing to understand about business overdraft rates in Australia: a lower rate means nothing if you can't get approved. The majority of Australian SMEs do not qualify for bank business overdrafts - the eligibility requirements are simply too strict. For these businesses, a non-bank overdraft at 18-25% p.a. that's actually accessible is worth infinitely more than a bank overdraft at 12% p.a. that's unavailable to them. See our comparison of the best overdraft lenders for a full breakdown.
Tax deductibility: Interest and fees on a business overdraft used for business purposes are generally tax deductible in Australia, reducing the effective after-tax cost. Speak with your accountant. General information only.
"Revolving" describes the facility, not a free-for-all: repay-and-redraw always operates within your lender's minimum repayment terms.
The same facility scales down for smaller operators. Sole traders and small SMEs commonly take small business overdrafts from $10,000, sized around one month of turnover, with identical criteria and process to larger facilities: $6,000+ monthly turnover, Equifax 550+, and 6 months of bank statements. Assessment is on bank statements, not tax returns, so a lean small business qualifies the same way a larger one does - and sole traders are eligible on exactly the same basis as companies.
For a small operator the practical questions are sizing and cost. Size the limit around one month of turnover and treat the line fee as the price of the standby: on a $20,000 facility the interest only runs while you are drawn. Worked examples: $20K overdraft cost and business overdrafts for sole traders.
There are three cost components. Model your own numbers in the business overdraft calculator - it shows weekly and monthly cost on any facility size and drawn balance.
Interest and fees on a facility used for business purposes are generally tax deductible - see the tax deductions guide. Detailed cost breakdowns by size: $20K | $50K | $75K | $100K | $200K
Many businesses use credit cards for working capital. An overdraft almost always costs less once merchant surcharges are counted, because you pay suppliers by bank transfer instead of card. Full breakdown with a cost comparison table: business overdraft vs credit card and credit card surcharges vs overdraft.
Since 1 July 2025, the ATO's general interest charge is no longer tax deductible, while business overdraft interest generally is. That changes the after-tax comparison for businesses carrying tax debt. Full comparison and the current numbers: ATO tax debt and business overdrafts.
Choosing between a bank and non-bank business overdraft is the most important decision for most Australian SMEs seeking working capital finance. Here's the complete picture:

Why use a broker: Applying directly to multiple lenders generates multiple credit enquiries - each one temporarily reduces your score and signals financial distress to the next lender. OverdraftMe submits to one lender only - the best match - protecting your score throughout the process.
Business overdrafts are used by Australian SMEs across every industry for consistent, predictable situations:
The most common use case in Australia. You complete work, invoice your client, and wait 14-60 days for payment. Meanwhile wages, materials and rent need to be paid. A business overdraft bridges this gap without requiring a new loan application each time.
Hospitality businesses in winter, construction in wet season, retail after Christmas - businesses with predictable quiet periods use overdrafts to maintain operations during slow periods and repay during peak trading.
From July 2026, super must be paid every payday - not quarterly. Businesses with large weekly wage bills need to fund super every week instead of every 90 days. A business overdraft provides the buffer. See our Payday Super checklist →
Tradies, manufacturers, retailers and hospitality businesses need to purchase materials, stock or produce before any revenue arrives. An overdraft funds these purchases and is repaid when the job is complete or the stock is sold.
BAS payments, PAYG withholding and super obligations all come due regardless of cash flow. An overdraft ensures these obligations are met on time - avoiding ATO penalties and protecting your credit file.
A large contract arrives but requires upfront investment. A key piece of equipment needs replacing. An opportunity to buy stock at a bulk discount. An overdraft lets businesses act on opportunities without waiting for cash to accumulate.

A business overdraft (sometimes called a business overdraft account) is a revolving line of credit that lets Australian businesses draw funds up to an approved limit and repay as cash flows in. Interest is charged only on drawn amounts - not the full limit. It is the most flexible working capital tool for Australian SMEs.
Every application is assessed case by case. As a guide: $6,000+ monthly revenue, an Equifax score of 550+, and an ABN typically 1+ year old (property owners) or 2+ years (non-property-owners) - strong candidates from 6 months. Business loans are available from a 6-month ABN. No tax returns, no financial statements, no property security required under $150,000.
With OverdraftMe, decisions come as fast as 1 hour. Same-day funding is possible for complete applications submitted in the morning. Banks take 2-8 weeks - non-bank lenders through OverdraftMe move in hours.
Costs include interest (14-30% p.a. for non-bank, 8-15% for banks), a line fee (0.5-2% p.a. on the approved limit) and an establishment fee (0.75-3% once). You only pay interest on amounts drawn.
Yes - non-bank lenders assess applications from 6 months of bank statements only. No tax returns, BAS statements or financial statements are required.
A business overdraft is revolving - draw, repay, draw again with no loan-style fixed repayments (lender minimum repayments may apply). A business loan is a lump sum with fixed repayments over a set term. Overdrafts suit ongoing cash flow gaps; loans suit specific one-off purchases.
Yes - many non-bank lenders consider applications with Equifax scores from 550+. A managed ATO debt does not automatically disqualify you. OverdraftMe works with lenders across the full credit spectrum.
Yes - completely free. OverdraftMe is paid by the lender on settlement, not by you. There is no cost to your business at any stage of the application process.

No. Property security is not required for business overdrafts under $150,000 with non-bank lenders.
In practice, yes. Both provide revolving access to funds up to an approved limit with interest only on drawn amounts. The terms are used interchangeably in Australia.
To fund the gap between paying costs and getting paid. Wages, rent and suppliers fall due weekly or monthly while invoices commonly pay 30 or more days later. An overdraft lets you draw for the gap, repay when invoices land and redraw next cycle, paying interest only on the drawn balance.
Many businesses hold one undrawn as insurance, because the only ongoing cost is the line fee on the limit. The practical advantage is timing: arranging the facility while your bank statements look healthy is easier than applying in the middle of a cash squeeze.
