Revolving credit vs business overdraft: which is right for your business?

Two of the most common working capital tools for UK SMEs share a similar structure: you agree a limit, draw what you need, and repay when your cash flow allows. But a business overdraft and a revolving credit facility are different products, and for many businesses, choosing the wrong one means either paying too much for something underused or relying on a facility that can’t actually do the job.

This guide helps you work out which is the right fit for your business, based on your specific circumstances.

The short answer

If you regularly borrow less than £10,000 for a few days at a time and your overdraft limit is comfortably sufficient, the overdraft is probably fine.

If you need more than your current limit provides, need a facility you can rely on without annual renewal uncertainty, want to borrow independently of your bank account, or need higher borrowing capacity for growth, stock, or seasonal peaks, a revolving credit facility is worth understanding properly.

Most of this article is for the second group.

What they have in common

Before getting into the differences, it’s useful to understand why these two products feel similar and why businesses often compare them directly.

Both products are:
-
— you have a limit agreed in advance, so you don’t need to apply every time you want to borrow
-
— as you repay, the available balance restores
-
— you pay interest on what you draw, typically calculated daily or monthly
-

This similarity is exactly why businesses switching from an overdraft to a revolving credit facility find the transition intuitive. The logic is the same; the mechanics are familiar.

The key differences

1. Where the facility lives

A business overdraft is attached to your bank account. When your account balance goes negative, you’re drawing on the overdraft. When funds clear, the balance reduces automatically.

A revolving credit facility is a standalone product. Funds are drawn into your account (any account) when you initiate a drawdown. You manage repayments separately.

Why this matters: The overdraft is frictionless because it lives inside your account. The revolving credit facility requires you to actively draw and repay. For most businesses, this is a trivial difference, but it means the revolving credit facility is completely portable. You’re not tied to the lender for your banking.

2. Facility size

This is often the decisive factor. The average UK SME overdraft through a high street bank is limited, commonly capped at £25,000–£50,000, sometimes less for newer businesses or sectors the bank views as higher risk.

Revolving credit facilities from specialist lenders typically go much higher. Juice Flex, for example, offers £25,000 to £1,000,000, subject to status and lending criteria.

Why this matters: If your overdraft limit is already insufficient, the cost comparison becomes largely irrelevant. You need more than the overdraft can provide.

3. Facility certainty

A business overdraft is repayable on demand. The bank can reduce or withdraw it at its discretion during an annual review, in response to a change in your business profile, or as a result of the bank’s own strategic decisions about sector exposure. This is not hypothetical: many UK businesses discovered this during the 2008–2009 financial crisis and again during COVID-19.

A revolving credit facility has a committed term. The lender cannot unilaterally reduce or withdraw the facility during the agreed period without cause. The commitment is mutual.

Why this matters: Businesses using an overdraft as a core working capital tool are exposed to facility risk. If the facility disappears, particularly during a difficult trading period when alternative finance is hardest to access, the consequences can be serious.

4. Arrangement fees and costs

Overdrafts typically charge an arrangement fee annually, calculated as a percentage of the limit. This is charged whether you use the facility or not. For a £30,000 overdraft at 1.5%, that’s £450/year in fixed costs regardless of usage.

Revolving credit facilities vary. Some charge arrangement fees, some don’t. Interest is typically charged only on drawn amounts.

Why this matters: Businesses that draw infrequently may find the overdraft costs more in practice than the headline rate suggests, because of the baseline arrangement fee. The comparison depends on how much you draw, how often, and for how long. See our cost comparison article for worked examples.

5. Speed to access

If you already have an overdraft in place, using it is instantaneous. You spend money, the balance moves into negative, done.

If you don’t yet have a facility in place, getting a revolving credit facility is typically faster than arranging or increasing a bank overdraft. Specialist lenders like Juice can complete the application and approval process in days rather than the weeks a bank formal credit application might take.

Why this matters: If you need a facility quickly and don’t have one in place, an alternative lender’s revolving credit facility may be accessible faster than your bank can review and approve a new or increased overdraft.

Decision framework: which is right for you?

Work through these questions to narrow down the answer for your business.

Question 1: Is your current overdraft limit enough?

If no, stop here. The overdraft cannot serve your needs regardless of how you answer the subsequent questions. A revolving credit facility is likely a better fit.

If yes, continue to Question 2.

Question 2: How long do you typically carry a balance?

A few days at a time — You’re using the overdraft for short-term account smoothing. This is exactly what overdrafts are designed for, and they typically do it well. The cost of a short-term draw at a competitive bank rate is usually reasonable.

Weeks or months at a time — You’re using the overdraft for working capital rather than account smoothing. This is where the cost comparison becomes more important, and where the lack of facility certainty becomes a genuine operational risk. A revolving credit facility may serve this need better.

Question 3: How important is facility certainty?

Not very — you have alternatives if the bank reduces the limit — The overdraft remains a reasonable option. Many businesses operate this way perfectly well.

Very — your operations depend on having the facility available — The bank’s ability to withdraw an overdraft on demand is a meaningful risk. A revolving credit facility with a committed term removes this risk.

Question 4: Is the overdraft the most expensive borrowing for your business?

If you’re paying an annual arrangement fee on an overdraft limit you always use in full, plus daily interest on a consistently high balance, your effective annual cost may be higher than a revolving credit facility with no arrangement fee (or a lower one) and interest only on drawn amounts.

This requires a specific calculation for your circumstances. The answer depends on your drawn balance, how often it varies, and the specific terms of both products.

Question 5: Is your banking relationship a consideration?

Some businesses prefer to keep all their financial relationships with one bank. It simplifies management and can support other banking services (loans, insurance, trade finance). An overdraft fits naturally into this model.

A revolving credit facility sits independently. This is an advantage for businesses that want to diversify their funding relationships, but a minor inconvenience for those who prefer consolidated banking.

Specific business scenarios

Scenario A: Retail business with seasonal stock requirements

Profile: A clothing retailer with £2M annual revenue. Needs to build stock worth £80,000 in September for Christmas peak. Revenue arrives November–December. January is quiet.

Overdraft assessment: Limit of £30,000 (typical for this size). Not enough.

Revolving credit assessment: A £100,000 revolving credit facility covers the full stock purchase. The business draws £80,000 in September, repays in chunks as Christmas revenue flows in. No early repayment penalty means they can pay down quickly in December and reduce their total interest cost.

Verdict: Revolving credit facility.

Scenario B: Professional services firm with invoice payment timing gaps

Profile: A consultancy with £600,000 annual revenue. Invoices clients on 30-day terms. Payroll is £40,000/month. Occasionally needs a bridge of £20,000–£30,000 between invoices clearing.

Overdraft assessment: A £35,000 overdraft covers the need. Cost per 15-day bridge at 12% EAR: approximately £250. Arrangement fee: £525/year.

Revolving credit assessment: A £50,000 revolving credit facility at a higher rate would cost slightly more per bridge draw, but with no arrangement fee and greater facility certainty.

Verdict: Depends on borrowing frequency. If bridges happen monthly, work the total annual cost for each option. If bridges are occasional, the overdraft may be cheaper. If facility certainty matters (client payments being the main revenue) the revolving credit facility’s committed term has value.

Scenario C: Growing e-commerce business needing a scalable facility

Profile: A D2C brand with £5M annual revenue and ambitious growth plans. Needs a facility that scales from £50,000 now to £250,000+ within 18 months as inventory requirements grow.

Overdraft assessment: A bank is unlikely to offer £250,000 on an overdraft basis. The annual review process makes scaling uncertain.

Revolving credit assessment: A specialist lender can provide a larger initial facility and review for increases on a defined schedule, working with the business rather than against it.

Verdict: Revolving credit facility.

Making the switch

If you currently use an overdraft and are considering moving to (or adding) a revolving credit facility, the transition is usually straightforward:

There’s no obligation to cancel your overdraft immediately, and for small short-term needs, it may remain useful alongside a revolving credit facility.
