A Guide to Revolving Credit Facilities

Some funding needs arrive as a lump: a machine, a refit, an acquisition. Others ebb and flow with trading: stock this month, a VAT bill next quarter, a slow paying customer in between. A term loan suits the first kind well and the second kind poorly, which is exactly the gap revolving credit facilities exist to fill.

In this guide, we’ll explain how revolving credit works, what it costs, how it compares with overdrafts, credit cards and business loans, and how to decide whether your business should have one.

What Is a Revolving Credit Facility?

A revolving credit facility gives your business an agreed borrowing limit that you can draw on whenever you need it, repay when cash comes in, and draw on again, as many times as you like. That’s the revolving part: unlike a loan, the money doesn’t arrive once and get repaid once; the facility sits available for whenever it’s needed.

You pay interest only on what you’ve actually drawn, for the time you’ve drawn it. If the facility sits unused, you pay little or nothing (though some lenders charge a small fee on undrawn funds), and there’s no obligation to use it at all. Think of it as a standing cash buffer: the business equivalent of not having to ask permission every time cashflow gets lumpy.

Facilities are typically reviewed and renewed annually, with limits set against the strength of your trading, and for established businesses they’re usually unsecured with a personal guarantee from directors; our guide to guarantors and personal guarantees explains what that commitment means.

How It Compares with the Alternatives

Revolving Credit vs a Term Loan

A term loan delivers a fixed lump sum with fixed repayments, which suits a defined purchase or project; you know the cost, the term and the end date. Revolving credit suits repeated, variable, short-lived needs, and costs nothing much while unused. The rule of thumb: borrow lumps with loans, smooth waves with revolving credit. If your need is really a one-off amount you’ll repay steadily, a working capital loan will usually be cheaper for the same money.

Revolving Credit vs an Overdraft

The two behave similarly, flexible borrowing up to a limit, but overdrafts are tied to your business current account and bank, tend to have modest limits, and can be reduced or withdrawn on demand. A revolving credit facility is a standalone product available from many lenders beyond your bank, generally with higher limits, and agreed terms for the facility period. For businesses that have outgrown their overdraft, a revolving facility is the natural next step.

Revolving Credit vs Business Credit Cards

Cards are convenient for small everyday spending and short interest free windows, but rates beyond that are high and limits low. A revolving facility provides actual cash into your account, at larger scale, and at rates generally better than card borrowing. The two coexist happily: cards for spending convenience, the facility for real cashflow support.

Revolving Credit vs Invoice Finance

If the wave in your cashflow is caused specifically by business customers paying slowly, invoice finance links funding directly to your sales ledger and scales with it automatically. Revolving credit is more general purpose: it doesn’t care why the gap exists. Businesses with slow payers often compare the two directly, and the deciding factors are usually cost and how comfortable you are involving a provider in your invoicing.

What Does a Revolving Credit Facility Cost?

Expect three possible components: interest on drawn balances, typically variable and higher than an equivalent secured loan rate, reflecting the flexibility and the lack of fixed security; an arrangement or renewal fee for setting up and maintaining the facility; and sometimes a non-utilisation fee, a small percentage on the undrawn portion.

Because interest only accrues while funds are drawn, the true cost depends entirely on how you use the facility. Drawn briefly and repaid promptly, revolving credit is cheap for what it does. Drawn fully and left outstanding for a year, it’s usually dearer than a term loan would have been, which is a sign the borrowing has become a lump and should be refinanced as one; our guide to business loan interest rates and fees shows how to run that comparison.

What Lenders Look For

Limits are set against your trading strength: turnover, cashflow patterns, profitability and credit record, evidenced through bank statements and accounts. Established businesses with steady revenues get the best limits and pricing. Expect the facility to be reviewed annually, and be aware that a deteriorating trading picture can mean a reduced limit at renewal, which is worth factoring into how heavily you lean on it.

Using a Facility Well

• Treat it as a buffer, not income: draw for timing gaps with a visible repayment source, not for spending the business can’t otherwise afford.

• Clear drawings promptly, since the product’s economics reward short borrowing cycles.

• Watch for creeping permanent balances, the classic sign you need a cheaper term loan instead.

• Keep it even when unused, if fees allow, because the facility is worth most on the day something unexpected happens.

Final Thoughts

A revolving credit facility is one of the most useful tools an established business can keep in the drawer: always available, only costing real money when used, and perfectly shaped for the lumpy, unpredictable cashflow that ordinary trading produces. Its one danger is quiet permanence, flexible borrowing that stops being flexible and starts being expensive. Use it for waves, refinance lumps into loans, and compare providers when you set it up, because limits, rates and fees vary widely across the market.
