How a business revolving line of credit works: the limit refills as you repay, what minimum repayments and clean-down clauses ask, and what review brings.

Why does a line of credit behave so differently from a business loan? Because the limit refills as you repay, so the same facility can fund stock in one month and wages the next. Here is how drawing and repaying actually work, what a clean-down clause asks of you, and what happens when the lender reviews the line.
Quick Answer
A revolving business line of credit lets you draw up to an approved limit, pay interest only on what you use, and draw again as you repay, so the available limit refills rather than running down like a term loan. Most lines carry a minimum repayment, some carry a clean-down clause, and all of them are reviewed, so the business line of credit you sign today is renewed on its conduct, not on its paperwork. The credit limit is the ceiling, not a balance you owe.
Also called: revolving credit facility, revolving business credit line. They describe the same product: a limit you can draw, repay and draw again. Banks tend to say revolving credit facility for larger, more formal agreements.
How does a revolving business line of credit work?
A revolving business line of credit works by giving you an approved limit that you draw from when you need funds and pay back when cash comes in, and the rule that makes it revolving is simple: the limit refills as you repay. You are charged interest only on what is drawn, typically calculated daily on the outstanding balance and debited monthly, rather than on the full limit.
Three numbers matter on any revolving line. The limit is the most you can have drawn at one time. The drawn balance is what you owe today. The available amount is the gap between the two. Every drawdown lowers the available amount, and every repayment raises it again by the same amount, less any interest and fees debited to the line.
In practice, a revolving line is a working capital tool. It is built for timing gaps: paying suppliers before customers pay you, carrying stock into a busy season, or covering a wage week that lands before a large invoice clears. If you want the side by side of how this sits next to a fixed loan, our line of credit and overdraft explainer covers drawn and undrawn balances in more depth.
Can you withdraw cash from a revolving line of credit?
You can usually move money out of a revolving line of credit, but how depends on how the facility is set up. Some lines sit as a separate account that you transfer from into your everyday business account. Others are linked so you can pay suppliers directly, and a few allow card or cash access. Which method is available varies by lender, and each transfer counts as a drawdown that starts interest on that amount from the day it leaves the line.
Revolving or non-revolving: what is the difference?
The difference between revolving and non-revolving credit is whether repaid money can be drawn again. On a revolving line it can, as long as the facility is open and in good standing. On a non-revolving facility, such as a drawdown facility or a term loan, each repayment reduces what you owe and the repaid amount is gone for good.
There is a middle ground worth knowing about. Some lines are revolving in name but amortise or step down, meaning the limit itself falls on a schedule, so part of every repayment is permanently retired. Lenders do this when they want a facility to wind down over time rather than sit open. Our overdraft vs line of credit guide explains why some lines amortise and how to spot it in an offer. Revolving equipment lines follow similar logic for asset purchases, set out in the revolving equipment facility entry.
| Facility shape | How you draw | How you repay | What happens to the limit |
|---|---|---|---|
| Revolving line of credit | Any time, up to the available amount | Minimum repayment or interest only, typically, with extra paid down as cash allows | Refills as you repay, until review |
| Business overdraft | Your transaction account goes below zero | Deposits reduce the debit balance; often no fixed repayment | Stays in place until review or recall |
| Amortising or step-down line | Up to a limit that falls on a schedule | Repayments include principal on a set path | Falls over time; repaid amounts are not all available again |
| Drawdown facility (non-revolving) | In set tranches, often against milestones | Scheduled repayments once drawn | Each drawn tranche is used up; it does not refill |
| Term loan | Once, in full, at settlement | Principal and interest over a fixed term | No limit to refill; the balance runs down to nil |
A revolving line is one of several facility types a lender can write, and our explainer on types of business credit facilities sets out the rest. At a larger size the same product picks up covenants and formal reporting, covered in our commercial line of credit insight.
What are the minimum repayments on a revolving line of credit?
The minimum repayment on a revolving line of credit is usually either the interest charged for the month or a small percentage of the drawn balance, whichever the facility specifies, and the rule varies by lender. On interest-only lines, the balance does not fall unless you pay more than the minimum. On percentage-based lines, a slice of principal is retired each month, and that slice becomes available to draw again.
The minimum is a floor, not a plan. A line that only ever receives the minimum will carry the same balance for years, which is exactly what reviewers look for. In our own files, the lines that renew without fuss are the ones where the balance swings up and down with trading, with deposits from sales paying the line down between draws.
- Interest only, typically. You pay the interest debited each month. Principal is repaid when you choose, from surplus cash.
- Percentage of balance. A set share of the drawn amount is due each month, plus or including interest. The share varies by lender.
- Sweep from receipts. Some facilities are linked to a collection account so customer receipts pay the line down automatically.
Overdrafts work differently, with no fixed repayment on many facilities and the risk of being repayable on demand. If that is the product you hold, our overdraft repayments post covers how they are charged.
What is a clean-down clause, and how do you meet it?
A clean-down clause is a condition that requires you to bring the drawn balance on the line to nil, or below a set level, for a stated period at least once in a set cycle, and meeting it means planning a quiet stretch of cash flow around that window. The clause exists because a clean-down proves the line is working capital, not long-term funding that should sit in a term loan.
Not every revolving line has a clean-down, and the wording differs from one agreement to the next. Some ask for a nil balance for a number of consecutive days each year. Others ask for the balance to stay under a percentage of the limit for a period. A few test it only at review. What counts as clean also differs: some lenders accept a balance funded from your own deposits, while others look closely at whether the money came from another lender.
| Clause element | What it usually means | What to check in your offer |
|---|---|---|
| Clean-down period | A run of days where the balance must sit at nil or under a set level | Whether the days must be consecutive, and whether the level is nil or a share of the limit |
| How often | Typically once in each facility year, sometimes more often | Whether you choose the window or the lender sets it |
| What counts as clean | The line is repaid from trading cash, not refinanced from another debt | Whether funds from a related account or another facility are excluded |
| If it is missed | Often a review trigger or a breach of a facility condition, varies by lender | Whether there is a cure period and what the lender can do next |
| Evidence | The lender reads it from the line's statement or your confirmation | Whether you must report it or the lender tracks it |
Meeting a clean-down is a cash flow exercise, not a paperwork one. The businesses that pass easily are the ones that pick their window before the year starts.
- Find your strongest cash weeks. Look at last year's cash flow and mark where receipts peak and supplier payments are lightest.
- Set the window inside that peak. If you can choose the timing, put the clean-down where the line would naturally fall anyway.
- Hold off large draws beforehand. Delay discretionary purchases in the weeks before so the balance is already falling.
- Keep the evidence. Save the statement that shows the clean period, in case the lender asks at review.
If the clean-down is not achievable in a normal year, that is a sign the balance has become structural, and a working capital loan or term facility may suit that portion better.
What are the disadvantages of revolving credit?
The main disadvantages of revolving credit are that the limit can cost money even when unused, the lender can change it at review, and the ease of redrawing makes it easy to let a balance grow. None of these rule a revolving line out, but each one is worth pricing before you sign.
- Fees on undrawn money. An unused limit can still cost a fee, varies by lender, whether it is called a line fee, an unused limit fee or a facility fee. Our rates and fees guide explains how these are charged on revolving facilities.
- Review risk. The limit is approved for a period, then reviewed. A lender can reduce or restructure it, so it is not a permanent entitlement.
- Discipline. Because repaid money is available again, it is easy to redraw it for non-urgent spending. The line then stops revolving and starts sitting.
- Security reach. Larger lines are often backed by a general security agreement or a director guarantee, which reaches beyond the line itself.
- Pricing. Variable pricing on a revolving line is usually higher than on a secured term loan, so it is an expensive home for long-term debt.
What happens when a balance never comes down?
When a revolving balance never comes down, lenders start treating it as permanent debt, and that changes the conversation at review. Revolving is not the same as permanent: a line that has sat near its limit for months is read as funding something the business cannot repay from trading. The usual fix is to move that hardcore portion into a term loan and keep the line for genuine swings, which our hardcore balance post walks through.
When does a lender renew, reduce or convert a revolving line?
A lender decides to renew, reduce or convert a revolving line at its scheduled review, or earlier if a trigger in the agreement is hit, and the decision rests mostly on how the line has been used. Renew means the limit continues on similar terms. Reduce means a smaller limit, sometimes stepped down over months. Convert means part or all of the balance is moved into a term loan with scheduled repayments.
What the reviewer reads is the line's own history: whether the balance swings, whether the clean-down was met, whether minimum repayments were on time, and whether trading supports the limit. Updated financials, serviceability and any change in security also feed in. Our post on how a line of credit limit is set covers what pulls a limit down at review, and the recalled facility guide covers what to do if the lender decides not to renew.
Common triggers for an early review include a missed clean-down, a balance sitting at the limit, a drop in turnover through the account, new tax debt, or a change in ownership or structure. Most agreements set out how much notice the lender gives before a reduction takes effect, and that notice is worth reading before you sign rather than after.
Small businesses also have some protection against one-sided terms. Unfair contract terms protections can apply to small business loan contracts, as set out on ASIC's unfair contract term protections page, and our business loan protections guide explains where those rules reach. For a line you want to keep on its current terms, the Business Owners Hub collects the planning posts we use before a review.
A revolving business line of credit is a limit, not a lump sum. You draw it when cash is short, pay interest only on what is drawn, typically, and the limit refills as you repay. Minimum repayments keep the line in good order, a clean-down clause proves it is funding working capital, and an unused limit can still carry a fee. At review, the lender decides to renew, reduce or convert based mainly on how the line has been run, so a balance that rises and falls with trading is the best case you can make.
Key takeaway: plan your clean-down window and pay the line down between draws, so the facility looks like working capital when it is reviewed.Frequently Asked Questions
A business revolving line of credit is a facility with an approved limit that you can draw, repay and draw again, paying interest only on the amount you have drawn. It suits uneven cash flow such as stock, wages or the gap before customers pay. The full mechanics of the product sit in our business line of credit guide.
You can withdraw money from a business line of credit, usually by transferring funds into your business transaction account or paying a supplier directly from the line. Some facilities allow cash access through a linked account and others only allow transfers, which varies by lender. Each withdrawal is a drawdown and starts interest on that amount.
Before applying for a business revolving line of credit, you should know how repayments are worked out, whether there is a clean-down clause, what fees apply to the unused limit and when the facility is reviewed. Those four terms decide how the line behaves after settlement more than the headline rate does. Our guide to reading business bank statements shows the account conduct lenders check first.
A small business can get a revolving line of credit, typically once it can show steady trading through its bank statements and, for larger limits, security such as property or a general security agreement. Smaller unsecured lines are common from non-bank lenders, with limits and pricing that vary by lender. Our post on lender types sets out what each kind of lender usually asks for.
The limit on a revolving line usually comes back as soon as your repayment clears, so the repaid amount is available to draw again. Timing depends on how the payment is made and when the lender processes it, which varies by lender. The exception is a line that steps down or amortises, where part of each repayment permanently reduces the credit limit.
