Whatever its size or industry, your business can experience fluctuations in cash flow. You might be waiting on invoices to be paid, finishing a project before receiving final payment or managing seasonal peaks and quieter periods.
When there’s a short-term cash shortfall, a business overdraft can help cover the gap, giving you flexible access to funds when you need them.
What is a business overdraft?
An overdraft is a facility attached to your business bank account that allows you to withdraw funds beyond a $0 balance. You’ll be approved to borrow up to a set limit and can access these funds whenever you like and spend it however you need, from smaller amounts to larger payments, without needing to reapply each time.
You can then make repayments at your own pace, giving you flexibility at times when cash flow isn’t steady. It might also be promoted by lenders as a business line of credit.
How does a business overdraft work?
When you apply for a business overdraft, your bank will review your business profile – including turnover, cash flow, trading history and existing liabilities – to determine how much you could be approved for and the interest rate you’ll pay. Once approved, your overdraft limit is linked to your business account, giving you flexible access to funds whenever you need them.
You’ll typically have the option to set up your overdraft as secured or unsecured:
- Secured overdrafts require a business asset, such as property or equipment, as collateral. These often come with lower interest rates and fees and may allow you to borrow more, but the approval process can take longer while the asset is assessed.
- Unsecured overdrafts don’t require collateral, which means they can be arranged more quickly. However, the credit limit is usually lower and interest rates may be higher. This option can be suitable for businesses that don’t have eligible assets or need funds fast.
Unlike a business loan, where you pay interest on the full lump sum, an overdraft only charges interest on the amount you actually use. This makes it a flexible option for covering short-term cash gaps – though interest can add up if balances aren’t managed carefully. You’ll also need to pay a line fee, an ongoing charge usually calculated as a percentage of the full overdraft limit, even if your balance is at $0.
Case study
A small landscaping business earns most of its revenue in spring and summer, with quieter winter months that can create short-term funding gaps. To cover wages and equipment costs during these slower periods, the business applies for a $50,000 unsecured overdraft.
Over the winter, the business draws $30,000 from the overdraft to cover expenses. Interest is charged only on the $30,000 borrowed, while a line fee applies to the full $50,000 limit.
As business picks up in the spring, the $30,000 is repaid, restoring the full $50,000 limit. With the balance now at $0, no interest is due on the repaid amount, though the ongoing line fee continues.
This keeps the full limit available as a safety net, giving the business flexible access to funds when needed. The business then picks up a contract with a local sports club and requires an additional ute and mower. Because the line of credit is still available, they can quickly secure the equipment totalling under $50,000 with no delays or additional paperwork.
What’s the difference between business loans and overdrafts?
Both business loans and overdrafts give your business access to funds, but they work in different ways and suit different needs. Here’s a look at how they compare:
| Feature | Business loan | Business overdraft |
|---|---|---|
| Structure | Lump sum borrowed upfront and repaid over a set term | Revolving line of credit linked to your business transaction account |
| Availability of funds | Full approved amount provided at settlement | Funds available to draw as needed up to your limit |
| Limits | Up to $500,000 unsecured Up to $4 million or more secured |
Up to $250,000 unsecured Up to $1 million or more secured |
| Terms | Fixed term from 1–30 years | Ongoing with no minimum term or fixed end date |
| Repayments | Regular scheduled repayments (weekly, fortnightly or monthly) | No fixed repayment schedule or amounts |
| Interest & fees | Interest charged on the outstanding loan amount Establishment fee Monthly service fee (set amount) |
Interest charged only on the amount used loans Establishment fee Monthly line fee (% of total limit) |
| Interest rates | Typically lower than overdraft | Typically higher than loan |
| Security | Secured or unsecured | Secured or unsecured |
| Eligibility | Based on business financials, trading history and credit profile | Based on business income, cash flow strength and credit profile |
| Use | Larger planned expenses such as equipment, vehicles or property | Managing short-term cash flow gaps or unexpected expenses |

How much do business overdrafts cost?
Overdrafts give your business flexible access to funds, but interest rates are generally higher than other types of business finance, and you’ll also pay an ongoing charge (line fee) that typically costs between 1% – 2% of the total overdraft limit, even if your balance is $0.
The total cost depends on:
- How much you borrow
- How quickly you repay
- The interest rate and line fee set by your bank
To see how the costs might pan out, let’s go back to the landscaping business from earlier.
The business has a $50,000 overdraft with a 14% interest rate and a 1.5% monthly line fee (working out at around $62.50 per month).
Over winter, the business draws $30,000 from the overdraft. If this balance is repaid in full after three months, the interest would be approximately $1,050.
However, if the balance isn’t repaid, interest quickly adds up. Over a full year, the $30,000 overdraft would cost $4,200 in interest.
The line fee for the year would add a further $750.
At this point, it may be worth comparing with other options, such as a business loan with lower interest rates and fees. For example, a $30,000 unsecured loan with 7% p.a. interest and a $10 monthly fee over 12 months would cost about $1,082 in interest and just $120 in fees, working out thousands of dollars cheaper.
While loans require regular repayments from the first month – offering less flexibility if income fluctuates – they may be a more manageable option for longer-term borrowing.
The pros and cons of business overdraft facilities
Pros
-
Simple application process
Applying for an overdraft is similar to a loan application but can often be completed more quickly. If you want to add it to your existing account, it’s as easy as logging onto your online account and submitting the request.
-
Flexible access to funds
You can draw on your overdraft at any time without needing additional approval. Repayments can also be made as funds become available, making it ideal if your cash flow fluctuates.
-
Can be used for almost anything
There are few restrictions on how you use your overdraft, provided it’s for business purposes. From bills and wages to equipment upgrades, special events, and more, it can cover a wide range of short-term business needs.
-
Can be cancelled at any time
You can close an overdraft facility at any time, provided your account balance is cleared. This makes it a flexible option if your business no longer needs it.
Cons
-
Higher rates and fees
Interest rates and fees on overdrafts can be significantly higher than other types of borrowing, especially if you don’t stay on top of repayments.
-
Not suited for long-term or large purchases
Overdrafts are designed for short-term funding, so they’re not ideal for major investments like expensive machinery or long-term projects.
-
False sense of security
Some businesses rely on overdrafts too heavily, using them to cover ongoing cash flow issues rather than addressing underlying problems.
-
Can be reduced or closed by the bank at short notice
Just as you can cancel the facility, so can your bank. They can demand immediate repayment if they believe the account is being misused or if your financial position changes.
Tips for minimising your business overdraft costs
-
Choose a secured overdraft
By opting for a secured overdraft instead of an unsecured one, you can reduce the interest and fees you may be required to pay.
-
Pay down your balance quickly
Clearing your balance as soon as possible can massively cut down on interest compared to chipping away at it slowly.
-
Only borrow what you need
Setting a higher borrowing limit than you need could tempt you to overspend, resulting in higher line fees and more interest.
-
Compare your options carefully
You don’t have to get an overdraft with your existing bank – you can open an overdraft and new account with any lender, so it’s worth comparing to find the best available deal.
Is an overdraft right for my business?
Whether a business overdraft is the right choice depends on your needs and cash flow patterns.
Your business may benefit from an overdraft if:
- You experience irregular cash flow, such as seasonal highs and lows, common in industries like agriculture and tourism.
- You’re a new or small business with limited cash reserves. An overdraft can cover unexpected expenses and provide flexibility when costs fluctuate.
- You operate on project-based work, where you only get paid upon completion. An overdraft can help cover staff wages and operational costs until invoices are settled.
- Your customers pay after delivery rather than upfront, creating temporary cash gaps that need bridging.
However, an overdraft may not be the best solution if:
- You have large, planned outlays such as purchasing equipment, vehicles, or property – a business loan or equipment loan is usually more suitable in these circumstances.
- You’re using it to cover ongoing cash flow problems. An overdraft won’t solve structural issues. Instead, consider auditing expenses, restructuring debt or finding ways to reduce costs.
