Business Line of Credit: How It Works, Rates & Who It Suits

Key highlights

• A pre-approved limit you can draw, repay and redraw at will
• Interest charged only on the funds you have drawn
• Sits ready in the background for opportunities or gaps
• Suits ongoing or unpredictable funding needs better than a term loan
• Secured and unsecured options depending on the limit and profile

What a line of credit is

A business line of credit is a revolving facility with a set credit limit that you can access whenever you need to, drawing down funds, repaying them, and drawing again without reapplying. It works a little like a business credit card in its flexibility, but typically with a higher limit, lower rates and the funds available as cash. You only pay interest on the balance you have drawn, not the full limit, so an unused line costs little to keep in place beyond any line fee. This makes it ideal for needs that are ongoing or hard to predict, giving you funding on tap rather than a one-time lump sum you must repay on a fixed schedule.

How a line of credit works

Once approved for a limit, you can transfer funds from the line to your business account as required, up to that ceiling. Interest accrues only on the drawn portion, usually calculated daily. As you repay, your available credit is restored, ready for the next need. Many facilities require only interest payments on the outstanding balance, with the principal repayable flexibly, though structures vary. Because it revolves, a line of credit is designed to be used repeatedly over its life rather than drawn once and closed. That ongoing availability is its defining feature: the facility is there in the background, giving you the confidence to act quickly when an opportunity or a shortfall appears.

Line of credit versus a term loan or overdraft

A term loan hands you a lump sum with fixed repayments and is best for a known, one-off cost. An overdraft is attached to your transaction account and shines for small, frequent dips. A line of credit sits between the two: a larger, standalone revolving limit for recurring or variable needs, often at keener rates than an overdraft, especially when secured. If you find yourself repeatedly borrowing for stock, projects or growth, a line of credit avoids the effort and cost of arranging new finance each time. Choosing between them comes down to whether your need is single or ongoing, and how large and predictable the amounts are.

Who a line of credit suits

Lines of credit suit businesses with recurring or lumpy funding needs, such as those that buy stock in cycles, run projects with staggered costs, or grow in unpredictable bursts. Wholesalers, importers, trades, and firms scaling up all benefit from having funds ready without committing to a fixed loan. It is also valuable as a strategic buffer, letting you jump on bulk-buying discounts or unexpected opportunities. It is less suited to a single large purchase best matched to a term loan, or to a business that would simply sit at the limit permanently, which points to a term facility instead. The ideal user draws and repays across the year as needs ebb and flow.

Eligibility, limits and rates

Lenders generally look for an active ABN, a period of trading (commonly six to twelve months) and consistent turnover to support the facility. Smaller limits may be unsecured based on cash flow, while larger limits often call for security such as property. Low-doc options can rely on bank statements and BAS instead of full financials. Facilities are available from around $5,000 up to $5 million, with unsecured limits typically up to $500,000, all indicative and subject to assessment. Rates start from around 7.49% p.a. for stronger secured facilities, with unsecured and short-term products priced higher depending on turnover, term, security and credit profile. Enquiring is a soft credit check that will not affect your credit score.

The broker advantage

Line of credit products vary in how they price the drawn balance, whether they charge line or undrawn fees, how repayments are structured and how the limit is reviewed. The right choice depends on how you intend to use it, and the difference between offers on the same profile can be substantial. Overdrive compares a panel of 80+ banks and non-bank lenders on one application, so you can match with a facility whose structure and cost genuinely suit your drawing pattern. We handle the paperwork, decode the terms, and line up real offers to compare, helping you secure flexible funding without overpaying for capacity you will not use.

Using your line of credit wisely

A line of credit rewards disciplined use. Because funds are always available and you only pay for what you draw, the temptation can be to lean on it permanently rather than as a revolving tool. The businesses that get the most from a line treat it as short to medium-term funding: drawing for a clear purpose such as a stock cycle or project, then repaying as the cash comes back in, which keeps interest costs down and the full limit ready for the next need. Keeping an eye on your drawn balance, and making a plan to pay it down rather than carrying it indefinitely, ensures the facility stays a flexible asset rather than a creeping cost. Used this way, a line of credit gives you agility without the drift into expensive long-term debt.

If your business needs funding on tap rather than a one-off lump sum, a line of credit could be the flexible solution that grows with you.
