What Is a Business Line of Credit?

Key highlights

• A revolving credit limit you draw, repay and draw again
• Interest usually applies only to the funds you actually use
• Different from a term loan's fixed lump sum and schedule
• Well suited to recurring, seasonal or unpredictable cash-flow needs
• Available secured or unsecured depending on your profile

The simple definition

A business line of credit is a revolving facility: a lender approves a maximum limit, and you draw funds from it as you need them, up to that ceiling. When you repay what you have drawn, that amount becomes available again. Interest is generally charged only on the balance you are actually using, not on the full limit sitting in reserve. Think of it as a reusable pool of funds standing ready rather than a one-off loan. This structure is what makes it so useful for the ups and downs of running a business, where costs and income rarely arrive in step. Limits and pricing depend on the lender's assessment of your turnover and profile.

How it works in practice

Once your line of credit is approved, you can draw down when a need arises, whether that is covering wages, paying a supplier early or handling an unexpected cost. You repay as cash comes in, and the repaid amount is available to draw again. There is no requirement to use the full limit; many businesses hold one largely untouched as a safety net. Because interest generally applies only to what you draw, an unused facility costs little to keep open, though fee structures vary by lender. The rhythm of draw, repay, redraw mirrors the natural flow of business cash, which is precisely why the product exists.

Line of credit versus a term loan

The clearest way to understand a line of credit is to contrast it with a term loan. A term loan hands you a fixed lump sum, repaid over a set schedule, and is ideal for a defined purchase such as equipment or premises. A line of credit gives you flexible, ongoing access to funds you can reuse, which suits recurring or unpredictable needs. With a term loan you pay interest on the whole amount from day one; with a line of credit you generally pay only on what you draw. Neither is better in the abstract; they solve different problems, and some businesses use both together for different purposes.

What businesses use it for

A line of credit shines when timing is the issue. Businesses use it to bridge the gap while waiting on customer payments, to buy stock ahead of a busy season, to smooth a quiet patch, to cover wages and suppliers, or to move quickly on a short-term opportunity. Because you draw only what you need and repay flexibly, it fits businesses with uneven cash flow, whether from seasonality, project billing or long payment terms. It is less suited to funding a single large asset, where a term loan generally works better. As a standing buffer for the day-to-day gaps, though, it is one of the more practical tools available.

Secured and unsecured versions

A line of credit can be unsecured, requiring no property security, or secured against property or assets. Unsecured facilities are typically available up to around $500,000, while secured arrangements can support larger limits, with funding across Overdrive's panel ranging from around $5,000 up to $5 million. Every figure is indicative and subject to lender criteria and assessment. Unsecured appeals to businesses wanting speed and simplicity, or those without property to offer; secured can unlock a larger limit or better pricing where assets are available. The right version depends on how much flexibility you need and what security you are willing to provide, a balance a broker can help you strike.

Eligibility and cost

Lenders generally look for an active Australian ABN, a minimum trading history often around six to twelve months, and a minimum monthly turnover. Low-doc options may rely on bank statements or BAS rather than full financials, helping newer or self-employed businesses. Pricing is product- and profile-dependent; stronger secured facilities can start from around 7.49% p.a., with unsecured and short-term products priced higher depending on turnover, term, security and credit profile. Rates are indicative and subject to assessment, never guaranteed. Newer businesses may still qualify subject to criteria. Any questions about how interest or fees interact with your tax position are best directed to your accountant rather than answered generally.

Finding the right facility

Because limits, pricing, security requirements and flexibility differ so much between lenders, the line of credit that suits your business is not always the first one offered. Applying to a single bank means accepting its view without seeing alternatives. Overdrive's Simon Kendrick compares a panel of 80+ banks and non-bank lenders on one application, so you can weigh limit, cost and flexibility side by side and choose what genuinely fits. For eligible applicants, this comparison often reveals a more suitable facility, and it avoids lodging several separate applications that each leave a footprint on your credit file, which can itself affect future borrowing.

Now that you know what a business line of credit is, the next step is seeing what your business could access. Simon Kendrick at Overdrive Business Loans can review your turnover, run a soft credit check that leaves no mark, and compare lines of credit across 80+ lenders to find a suitable limit and price. For eligible applicants, a facility can be arranged efficiently, sometimes with funds available within 24 to 48 hours once set up.
