How does a revolving credit facility work? (And is it right for your business?)
A revolving credit facility is one of the most useful financial tools available to UK businesses, and also one of the most misunderstood. The name makes it sound technical. It isn't. Once you understand the mechanics, it's actually very intuitive.
This guide walks through exactly how a revolving credit facility works, with a practical worked example and a clear breakdown of costs, so you can judge whether it fits the way your business operates.
The core mechanic: draw, repay, revolve
A revolving credit facility gives your business access to a pre-approved credit limit. You draw funds from that limit when you need them, repay when you have the cash, and the repaid amount becomes available to draw again. That's the revolving part.
It's not a one-time loan. There's no fixed repayment schedule. You don't receive a lump sum and then work through a set number of monthly instalments. Instead, the facility sits alongside your business, available whenever you need it, for as long as it's in place.
The simplest analogy: imagine a reservoir with a defined capacity. You draw from it when you need water. When it rains, when revenue comes in, the reservoir refills. You can draw and refill as many times as you need.
A worked example
Let's make this concrete with a UK e-commerce business.
The business is an online homeware retailer turning over £2.5M per year. They carry significant inventory and typically need to pay suppliers 60–90 days before the goods sell.
Juice approves them for a £150,000 revolving credit facility.
Here's how the facility looks over a typical quarter:
| Month | Action | Amount | Available Balance |
|---|---|---|---|
| January | Facility approved | — | £150,000 |
| January | Draw to pay supplier invoice | £60,000 | £90,000 |
| February | Partial repayment from January sales | £25,000 repaid | £115,000 |
| February | Draw for February stock order | £40,000 | £75,000 |
| March | Good sales month — large repayment | £65,000 repaid | £140,000 |
| March | Small draw for marketing spend | £10,000 | £130,000 |
| April | Repay remaining balance | £10,000 repaid | £150,000 |
At no point did the business take the full £150,000. At no point did they pay interest on the full £150,000. They drew what they needed, when they needed it, and repaid as cash came in. The facility kept revolving, available throughout, working around the natural rhythm of the business.
Compare that to a term loan: the business would have received £150,000 in January and started paying fixed monthly instalments from the following month, regardless of whether sales had come in yet. They'd also be paying interest on £150,000 even in months when their actual need was far lower.
How interest is calculated
One of the most important features of a revolving credit facility is that interest accrues only on the amount you've drawn, not on the full credit limit.
Using the worked example above:
- In January, interest accrues on £60,000 (not £150,000)
- After the February repayment, interest accrues on £35,000 (the £60,000 draw minus the £25,000 repayment)
- After the February draw, interest accrues on £75,000
You're never paying for money you haven't used. That's a meaningful cost difference compared to a term loan, where interest accrues on the full outstanding balance from day one, even if you haven't deployed all the capital yet.
Interest is typically charged monthly and calculated on the average daily balance. Check the specific terms with any lender, as the structure can vary.
The repayment cycle
Unlike a term loan, there is no fixed monthly repayment amount with a revolving credit facility. You repay what you can, when you can, subject to any minimum repayment terms your lender specifies.
This flexibility is designed to match the reality of business cash flow, which is rarely smooth. A good month might let you clear a large portion of the balance. A quieter month might mean a smaller repayment. The facility accommodates both.
With Juice Flex, there are no early repayment penalties. If a big payment comes in and you want to repay the full balance tomorrow, you can do that and you'll immediately stop accruing interest on the repaid amount. The full balance becomes available to draw again.
What it costs: the fee structure
Revolving credit facilities typically have several cost components. Understanding all of them prevents surprises.
Interest rate — Applied to drawn funds. This is the primary cost. The rate you're offered depends on your business financials, trading history, and risk profile. It varies by lender and by borrower.
Arrangement fee — Some lenders charge a one-time fee to set up the facility, typically a percentage of the credit limit or a fixed fee. Not all lenders charge this, so check before you apply.
Facility fee — Some lenders charge an ongoing fee simply for having the facility available, whether or not you're drawing from it. This makes more sense for very large facilities where the lender is committing underwriting resource. For smaller SME facilities, it's less common.
Draw fee — Some lenders charge a small fee, typically a percentage of the draw amount, each time you access funds. Again, not universal, so check the terms.
No early repayment penalty (Juice Flex) — This is worth highlighting because it's not a given across all lenders. Juice Flex does not charge you for repaying early. Some term loan providers do, so if you're comparing products, this is a point worth verifying.
When comparing two lenders on cost, the only fair comparison is the total cost of funds for your expected usage pattern. A facility with a slightly higher interest rate but no draw fees or facility fees may cost you less overall. Run the numbers for your specific scenario.
How drawdowns work in practice
Once your revolving credit facility is live, accessing funds is straightforward. With Juice Flex:
- Log into your Juice account
- Enter the amount you want to draw (up to your available balance)
- Confirm the transfer to your business bank account
- Funds arrive in your account
The process is designed to be quick. When a supplier payment is due or a business opportunity materialises, you don't want to be waiting days for a manual process to clear. The funds should be there when you need them.
When a revolving facility makes sense
The product works best for businesses where cash flow is variable or cyclical, where the timing of revenue doesn't perfectly match the timing of expenses.
Classic use cases:
- Covering supplier payments while waiting for customer payments to clear (particularly common in manufacturing, wholesale, and professional services)
- Funding inventory before a peak trading period (retail, hospitality, e-commerce)
- Bridging a VAT payment while large invoices are still outstanding
- Taking advantage of a short-notice opportunity, such as a bulk buy at a discount, a time-sensitive marketing push, or a new contract that requires upfront cost
- Managing payroll during a month where receivables are running late
- Funding growth without the rigidity of a fixed repayment schedule fighting against variable revenue
When a revolving facility might not be the best fit
Revolving facilities are not the right product for every capital requirement.
If you need to fund a large, long-life asset like equipment, a vehicle, or property refurbishment, an asset finance product or term loan may be more appropriate. These are typically longer-tenure, fixed-repayment products that match the life of the asset being funded.
If you want certainty over your repayment commitments for budgeting purposes and prefer a fixed schedule, a term loan provides that predictability. The flexibility of a revolving facility is a feature for most businesses, but some prefer structure.
If your cash flow challenges are about the business not generating enough revenue to service its costs rather than timing, a revolving facility won't solve that. It addresses cash flow timing, not underlying profitability.
Is it right for your business?
Ask yourself three questions:
-
Does my business have timing gaps between when I spend and when revenue arrives? If yes, a revolving facility addresses that directly.
-
Is my cash flow variable month-to-month? If yes, the flexible repayment structure is a real advantage over a fixed-term loan.
-
Do I need capital available on an ongoing basis rather than for a single, defined purpose? If yes, a revolving facility is more efficient. You're not reapplying for new loans every few months.
If you answered yes to at least two of those, Juice Flex is worth exploring. The application is fast, there's no impact to your credit score to apply, and you can see your eligibility in minutes.
