MCA vs Revolving Credit: Which Funding Suits Your Business
A merchant cash advance and a revolving credit facility both solve a similar problem: access to working capital without a rigid monthly repayment schedule. But the structures behind them are very different, and so are the costs, the cash flow impact, and the long-term effect on the business.
This guide compares the two directly: how each works, what they cost, when one fits better than the other, and how to decide which is right for your business.
For a wider view of how both options fit alongside other UK SME funding structures, see our pillar guide on revolving credit facilities for UK SMEs.
The short version
A merchant cash advance is a lump sum of capital paid upfront and repaid through a percentage of every card sale until a pre-agreed total has been collected. The cost is expressed as a factor rate — a multiplier on the original advance.
A revolving credit facility is a pre-approved credit limit that you draw from as needed, repay as cash comes back in, and draw again. Interest is charged only on what you actually use.
For most UK SMEs that qualify for both, a revolving credit facility will be significantly cheaper, more flexible, and more useful over time. Merchant cash advances genuinely fit in specific situations — urgent funding, businesses that cannot access conventional credit, or short-term opportunities where speed outweighs cost. Outside those situations, the comparison usually favours revolving credit. See the full Merchant cash advance guide here.
The rest of this guide walks through why.
How each one works
Merchant cash advance
A provider pays the business a lump sum — typically £10,000 to £150,000 in the UK market. The business agrees to repay a fixed total, calculated using a factor rate. A factor rate of 1.3 on a £50,000 advance means the business owes £65,000 back.
Repayment happens automatically, through a holdback percentage taken from every card sale until the full amount is cleared. A typical holdback sits between 5% and 20% of daily card revenue. Repayment continues until the factor-rate total is collected — however long that takes.
For a full explanation of the mechanics and costs, see our guide on how merchant cash advances work and the factor rate explainer.
Revolving credit facility
A lender approves the business for a credit limit — typically £50,000 to £1,000,000 for established UK SMEs. The business can draw any amount up to the limit, whenever needed. Interest is charged only on the drawn balance.
As the business repays, the available balance resets. A business with a £100,000 facility that draws £40,000 and repays it is back to £100,000 — available to draw again, without reapplying.
Repayment terms are structured and predictable: fixed Direct Debits over an agreed period (commonly up to 24 months per draw), often with the option of interest-only periods.

Cost compared
This is the single biggest practical difference between the two products.
A direct comparison
Take a business that needs £50,000 for six months to fund a stock order.
Merchant cash advance. £50,000 at a factor rate of 1.3. Total repayment: £65,000. Cost: £15,000.
Revolving credit facility. £50,000 drawn from a £75,000 facility at 2% monthly interest, repaid evenly over 6 months. Approximate interest cost: £3,000.
Same funding amount, same six months of use. One costs five times more than the other.
The comparison narrows in specific circumstances — for example, if the RCF rate is higher, or if the MCA is repaid very slowly, or if origination fees are applied. But the direction of the comparison is consistent: for businesses that qualify for both, revolving credit is usually materially cheaper.
Cash flow impact
The structural difference between the two products shows up most clearly in how they feel day to day.
The MCA cash flow pattern
Every card sale is deducted at source. If the holdback is 15%, that means 15% of every card transaction is taken before it reaches the business account. Busy day: bigger deduction. Slow day: smaller deduction.
The intuition here is appealing — repayments "flex with sales." The reality is more complicated:
- The deduction is taken from top-line revenue, not net margin. A business with a 15% net margin and a 15% MCA holdback pays its entire card-sale margin to the advance until it clears.
- On strong days, repayment accelerates — which raises the effective APR (same fee, less time).
- On slow days, repayment decelerates — but cash flow pressure continues for longer.
- There is no pause button. The holdback continues through quiet periods, seasonal dips, and slow weeks.
The RCF cash flow pattern
Repayments are structured Direct Debits on an agreed schedule, separate from card sales. The business decides when to draw and how much. Interest accrues only on the drawn balance, for the time it is drawn.
This gives the business meaningful control:
- Draw £50,000 for three months, then repay it. Cost: interest on £50,000 for three months.
- Draw nothing for six weeks. Cost: zero.
- Draw £20,000 at a time, in sync with inventory cycles. Cost: interest only on those draws, for those periods.
The trade-off is that RCF repayments are predictable obligations rather than sales-linked ones. A business with genuinely volatile revenue that dips below the drawn amount plus interest may find structured Direct Debits harder to absorb than a holdback. This is the one cash flow scenario where an MCA's structure can feel easier.
For a deeper look at cash flow use cases, see our guide on what businesses use revolving credit facilities for.
Speed and eligibility
Speed and access are the two areas where MCAs genuinely have an edge.
The headline: MCAs approve faster and approve businesses that many RCF providers would decline. That is the product's genuine value. It exists because there is a real market for capital that cannot wait two weeks and cannot pass a bank's credit check.
The flip side is that once an RCF is in place, the speed advantage evaporates. Drawing from an existing facility can take as little as 24 hours. An RCF is slower to set up; it is not slower to use.
For businesses that expect to need funding repeatedly, the upfront effort of setting up an RCF pays off quickly.
Reusability and long-term planning
This is the most overlooked difference between the two products.
An MCA is a one-off transaction. When it is repaid, it is finished. If the business needs funding again, it applies again — with a new factor rate, new fees, and potentially a different provider.
A revolving credit facility is a relationship. Once approved, it stays in place. Draw, repay, draw again. No reapplication. No new fees for each draw.
For a business with recurring funding needs — which is most UK SMEs with seasonal patterns, inventory cycles, or invoice-payment gaps — this structural difference compounds over time.
Consider two businesses, both needing £40,000 of funding three times a year.
Business A uses MCAs. Three separate applications. Three separate factor rates (often rising each time). Three sets of origination fees. Stacking risk if any of the advances are still being repaid when the next one is taken. No record of a consistent funding relationship.
Business B uses a revolving credit facility. One application. One facility. Three draws over the year. Interest only on the drawn balances for the drawn periods. A track record with a single lender that often leads to increased limits over time.
Over a year, Business A's costs are typically 3 to 5 times higher. Over three years, the difference compounds further.
When an MCA is the right tool
There are specific situations where a merchant cash advance is genuinely the better option.
You cannot access cheaper funding. If banks and RCF providers have declined and the alternative is no funding at all, an MCA may be the practical choice. In this scenario, the comparison is not "MCA vs cheaper loan" — it is "MCA vs missed opportunity."
You need funds in 48 hours and don't already have a facility. Setting up an RCF takes time. If there is a genuine emergency — a supplier ultimatum, equipment failure, a closing deadline — and no facility is in place, an MCA can move faster.
The funding need is clearly one-off and short. A 2–3 month opportunity where the advance will be repaid by the activity it funds. If the time window is short, the effective APR is higher — but the absolute cost can still be acceptable.
You have strong, consistent card revenue and genuinely prefer the sales-linked repayment model. For some hospitality and retail businesses, a holdback against card sales feels more comfortable than structured Direct Debits. This is a legitimate preference, though it is worth calculating whether the premium is worth the comfort.
The business is too new for conventional lenders. MCA providers often accept 6 months of trading where RCF lenders want 12 or more. If the business is genuinely early-stage, the option set is narrower.
When revolving credit is the right tool
For most UK SMEs that qualify, revolving credit is the better structural fit in most scenarios.
You have recurring or seasonal funding needs. Inventory cycles, marketing spend before peak periods, payroll through slow months, VAT bills. Any situation where funding will be needed more than once in a 12-month window.
You want to compare the cost against other forms of funding. An RCF's pricing is transparent and comparable. An MCA's true cost requires calculation and context.
Your margins are thin. A top-line holdback on card sales eats into revenue that may already be committed to costs. Interest on a drawn balance — billed separately from sales — keeps the two clearly separated.
You want flexibility in when and how to repay. RCFs often allow early repayment at no cost, structured interest-only periods, and Direct Debit flexibility. MCA repayment continues at the holdback pace until it clears.
You're planning ahead rather than reacting. If funding is part of a strategy rather than an emergency, the setup time for an RCF is not a constraint.
You want funding that can grow with the business. RCF limits often increase over time as the relationship matures. MCAs do not build that kind of relationship.
How to decide
Four questions, in order.
1. Is this a one-off need, or will it repeat?If it will repeat — almost always true for SMEs — an RCF is structurally better suited.
2. Do I qualify for a revolving credit facility?If yes, price an RCF before committing to an MCA. The cost comparison is usually decisive. For more on what lenders assess, see our guide to revolving credit approval factors.
3. Is speed the binding constraint?If funding is genuinely needed within 72 hours and no facility is in place, an MCA can move faster. This is the one scenario where the premium is often worth paying.
4. What is the effective APR?Before signing an MCA, convert the factor rate into an APR using the expected repayment window. Compare it to RCF pricing. If the gap is large and the speed advantage is not decisive, the direction of the comparison should be clear.
If two products solve the same problem, the cheaper one is usually the right one — unless something else (speed, access, or a specific cash flow need) makes the premium worthwhile. For most UK SMEs, that tips the decision toward revolving credit.
See how Juice Flex compares
Juice does not offer merchant cash advances. For UK SMEs that qualify, Juice Flex is a revolving credit facility designed to solve the same underlying funding needs — inventory, marketing, cash flow gaps — at a meaningfully lower cost, with the added benefit that the facility stays in place and can be drawn again once repaid.
Frequently asked questions
What's the main difference between an MCA and a revolving credit facility?An MCA is a one-off lump sum repaid through a percentage of card sales, priced using a factor rate. A revolving credit facility is a pre-approved credit limit that can be drawn, repaid, and redrawn, with interest charged only on what is drawn. MCAs are typically faster to set up but significantly more expensive.
Which is cheaper, an MCA or revolving credit?For businesses that qualify for both, a revolving credit facility is almost always cheaper — often by a factor of 3 to 5 on the same funding amount over the same period. MCAs become more competitive only when a business cannot access cheaper funding or when the repayment window is very short.
Can I get a revolving credit facility instead of an MCA?Often yes, for UK businesses with 12+ months of trading and stable monthly turnover. The application takes longer than an MCA — usually 24 hours to a week — but the ongoing cost is materially lower. It is worth pricing both before committing.
Are MCAs faster than revolving credit?To set up: yes, usually. To use, once a facility is in place: no. A revolving credit facility approved last month can be drawn in 24 hours. An MCA has to be applied for each time.
Can I refinance an MCA with a revolving credit facility?In some cases, yes. Businesses that have taken an MCA and now qualify for conventional funding can use a revolving credit facility or term loan to repay the MCA and reduce their ongoing cost. The economics depend on the remaining MCA balance and the cost of the replacement funding.
Do I need card sales to get a revolving credit facility?No. Revolving credit is assessed on overall business performance — turnover, cash flow, trading history, credit profile. Card sales may form part of the revenue picture but are not a requirement. MCAs, by contrast, are specifically structured around card sales data.
Is a personal guarantee required for either?Often for MCAs, sometimes for revolving credit (especially for smaller facilities). The details vary by provider. Always read the security requirements carefully before signing.
Both merchant cash advances and revolving credit facilities have a legitimate place in the UK funding landscape. The right choice depends on the specific situation — and the cost difference is significant enough that the comparison is worth doing properly.
Before signing an MCA, price a revolving credit facility. Before ruling out an MCA, check whether a revolving credit facility is realistically available in the time frame you need.
