Why Your Bank Offers an Overdraft, Not a Line of Credit
Your bank reaches for an overdraft because it is the facility it can approve fastest against your transaction account, not because it is the better cashflow tool. A revolving line of credit charges interest on the drawn balance only and gives you standby headroom you rarely fully draw. The real difference is often who places the facility, not which product you qualify for.
Quick Answer
Your bank often defaults you into an overdraft because it is the simplest facility to approve against an account it already holds. A broker can place a genuine non-bank revolving line of credit instead, a form of working capital finance that charges interest on the drawn balance only.
Why Your Bank Reaches for an Overdraft First
Your bank offers an overdraft because it is the facility its credit team can approve fastest against the transaction account you already hold, not because it is the stronger cashflow structure. The bank overdraft default is an operational choice on the lender's side, and where this commonly lands is a self-employed owner paying for flexibility they could often get on better terms through a genuine overdraft alternative.
An overdraft sits on top of your everyday account and lets you dip below zero up to an agreed limit. It is quick to bolt on, which is exactly why a branch reaches for it. The trade-off is that the pricing, review conduct and limit are set by the same institution that holds your account, and the limit is often modest relative to the working capital a growing business actually carries. General guidance on how these facilities work is set out by the regulator at Moneysmart.
Line of Credit or Overdraft: What Passes, What Fails
A revolving line of credit and a bank overdraft both give you on-demand cash, but they pass and fail on different things that matter to a self-employed business. The core split is structure: a line of credit is a standalone revolving facility, while an overdraft is an extension of your transaction account. That structural difference is what drives the cost, the headroom and the renewal experience.
Where a Line of Credit Passes
- Interest on the drawn balance only, undrawn funds cost less
- Standby headroom you rarely fully draw, sized to the business
- Sits separate from your trading account, so it survives a bank switch
- Non-bank options read a self-employed serviceability picture more flexibly
Where an Overdraft Falls Short
- Limit is often capped low relative to real working capital needs
- Tied to the bank that holds your account, less leverage at review
- Review and renewal conduct sits entirely with one institution
- Can be reduced or pulled when the bank reassesses the account
Neither facility is wrong in every case. A small, occasional shortfall on a stable account can be fine on an overdraft. But once the gap is recurring or the business is scaling, a working capital facility built as a proper revolving line usually fits the pattern better.

How a Broker Places a Non-Bank Revolving Line
A broker reaches lenders your bank branch cannot, which is how broker placement of a non-bank revolving facility puts a genuine business line of credit on the table instead of the overdraft the bank defaults to. The bank can only offer what sits on its own shelf. A broker works across major banks, non-bank lenders and specialist funders, and matches your file to the one whose appetite fits a self-employed serviceability read.
That placement step is where this commonly lands in your favour. A single application goes to the lender most likely to approve the structure and the headroom you actually need, rather than the structure your existing bank finds easiest to issue. If you want to test which facility your file supports, you can check eligibility before committing to anything.
It also changes your position at review. Because a non-bank revolving line sits separate from your trading account, your review and renewal conduct is assessed on the facility itself, and you keep the option to move banking relationships without unwinding your cashflow cover. That separation is a quiet but real advantage over an account-tied overdraft, and it is a structural feature, not a pricing gimmick.

Which Facility Fits Your Cashflow Gap
The right facility depends on the shape of your cashflow gap, not the headline rate. A revolving line of credit suits a recurring, hard-to-time gap where you want headroom on standby. An overdraft can suit a small, infrequent dip. A term working capital loan suits a known, one-off funding need with a clear repayment horizon.
Your bank reaches for an overdraft because it is the fastest facility to issue against an account it already holds, not because it is the strongest cashflow tool. A revolving line of credit charges interest on the drawn balance only, gives you standby headroom you rarely fully draw, and sits separate from your trading account. The real difference between the two is usually who places the facility, and a broker can reach the non-bank revolving line a bank branch defaults away from.
Key takeaway: Do not accept the overdraft just because it is the facility your bank offers first. Match the facility to your cashflow gap and let a broker reach the lender whose appetite fits.Frequently Asked Questions
Your bank offers an overdraft instead of a line of credit because the overdraft is the facility its credit team can approve fastest against your existing transaction account, not because it is the stronger cashflow structure. A genuine revolving line of credit often sits with non-bank lenders that a broker reaches on your behalf.
A business line of credit is generally a more flexible facility than a bank overdraft for self-employed owners because it charges interest on the drawn balance only and gives you standby headroom you rarely fully draw. The right choice still depends on the shape of your cashflow gap rather than the headline rate.
On a revolving line of credit you pay interest on the drawn balance only, not on the full approved limit, which is part of what makes it a useful form of working capital finance. The undrawn portion sits as standby headroom and typically attracts a smaller facility or line fee that varies by lender.
A broker can often place a genuine non-bank revolving facility that a bank branch will not offer, because broker placement reaches specialist and non-bank lenders that read a self-employed serviceability picture differently. This is how a business line of credit gets onto the table instead of the overdraft the bank defaults to.
A line of credit is one form of working capital finance, specifically a revolving facility you draw down and repay as cashflow moves. Other working capital structures, such as a term working capital loan or invoice finance, suit different gap shapes, so the facility should be matched to the gap rather than chosen by name.
