Switching From a Merchant Cash Advance: Cost Mechanics and What to Consider

This article is part of our Alternatives to Merchant Cash Advances guide for UK businesses.

If you have used a merchant cash advance and are now wondering whether there is a better option, this guide is written for you. There is already a broad comparison of MCAs and revolving credit facilities available on this site. This article goes deeper. It focuses on the cost mechanics that matter when you are weighing up a switch, the questions to ask before you move, and the specific scenarios where switching is financially worthwhile.

The goal is to give you enough detail to run the numbers on your own business, not just read a general overview.

Why the cost comparison is more complex than it looks

When people compare an MCA to a revolving credit facility, the instinct is to compare the headline numbers: a factor rate of 1.25 against an annual percentage rate. But that comparison is not straightforward, because the two products measure cost in fundamentally different ways.

A factor rate tells you the total amount you will repay. An annual percentage rate tells you the cost per year on an outstanding balance. These are not the same unit of measurement.

To compare them fairly, you need to convert the MCA factor rate into an effective annualised cost. And to do that, you need to know how long repayment will take, which depends on future card sales that you cannot predict with certainty at the point of signing.

This is not a technicality. It is the core problem with MCA cost transparency. The total cost is fixed, but the effective cost depends on a variable you do not control.

The MCA cost structure in detail

When you take an MCA, you agree to repay a fixed total amount. That amount is calculated by multiplying the advance by the factor rate.

Repayment happens automatically through a holdback: a percentage of every card transaction is deducted by the provider before the funds reach your account. You have no scheduled monthly payment to plan around. The repayment pace is entirely governed by how much card revenue you generate.

What this means for your cash flow:

Every card transaction during the repayment period is reduced by the holdback percentage. On a day when you take £4,000 in card sales with a 15% holdback, £600 goes to the provider and £3,400 reaches your account. This continues for every transaction until the total agreed amount has been collected.

In strong trading periods, the holdback feels less noticeable because overall revenue is higher. In quiet periods, you are still losing 15% of every transaction at exactly the point where cash flow is most constrained. Your fixed costs (rent, payroll, supplier invoices) do not move in line with your card revenue.

The timeline problem:

Because repayment speed varies with card sales, you cannot know precisely when you will finish repaying. A business that projects 12-month repayment based on current card volumes may find itself still repaying at 18 months after a difficult quarter. The total cost does not change. But the length of time that cost applies to your cash flow is unknowable at signing.

The revolving credit cost structure in detail

A revolving credit facility works from the opposite principle. The lender approves a credit limit once. You draw from it as needed, repay on agreed terms, and the limit becomes available again without reapplying.

Interest is charged on the amount you draw, for the period you hold it, at an agreed rate. If your approved limit is £100,000 and you draw £30,000, you pay interest on £30,000, not on the full £100,000. If you repay after 3 months rather than 6, you pay 3 months of interest, not 6.

What this means for your cash flow:

Repayments are scheduled. You know the amount and the date. This integrates into cash flow planning in a way that a variable holdback simply does not. You can model your working capital position for the next 3, 6, or 12 months with the credit facility as a known line item.

The facility revolves, which means you are not starting from zero after each repayment. A business that regularly needs working capital for stock purchases, seasonal gaps, or growth investment has a permanent tool available rather than a one-time advance that needs to be rebuilt each cycle.

A direct cost comparison: worked example

Here is the same business scenario modelled under both products.

The business: Meridian Interiors, a trade kitchen supplier in Manchester

Option A: Merchant cash advance

Estimated repayment at current card volumes: £50,800 / £4,550 = approximately 11 months

Effective annualised cost at 11-month repayment: approximately 30%

But Meridian has a quiet January and February. Card sales average £22,000 in those 2 months. Holdback collection drops to £2,860 per month. The repayment period extends to approximately 14 months.

Total cost paid: £10,800 (unchanged).
Effective annualised cost at 14 months: approximately 23%.
Duration of holdback impact on cash flow: 14 months.

Option B: Revolving credit facility (subject to status and lending criteria)

If Meridian's January and February are difficult, the facility does not automatically extract money from card transactions. Repayments are fixed and scheduled, based on the agreed terms at the time of draw. The business knows what is coming out and can plan around it.

If Meridian wants to repay the £40,000 draw early because a good month makes it possible, they can. With no early repayment penalties, doing so reduces the total interest paid. With an MCA, repaying early saves nothing: the full £10,800 fee is owed regardless.

After the £40,000 draw is repaid, the full £100,000 facility is available again. Meridian can draw again for the next stock order without going through a new application.

The switching decision: five questions to work through

If you are currently using or considering an MCA and want to assess whether a revolving credit facility would be a better fit, these questions help frame the decision.

1. How predictable is your card revenue month to month?

If your card sales are very consistent with minimal seasonal variation, the MCA holdback is more predictable and easier to plan around. If your revenue has significant swings, the variable repayment pace of an MCA creates cash flow uncertainty that fixed-term repayments do not.

2. Do you need to access capital more than once a year?

Each MCA covers a single advance. To borrow again, you must reapply and receive a new offer. Some providers offer top-ups while repayment is ongoing, but these apply a new factor rate to the combined balance, which can accelerate total cost.

A revolving credit facility is designed for repeated use. If working capital is a recurring need rather than a one-off requirement, the facility model is more efficient over time.

3. Do you want to be able to repay early without losing money?

With an MCA, the full agreed amount is owed regardless of when you finish repaying. Repaying in 6 months instead of 12 does not save you anything. With a revolving credit facility, early repayment reduces total interest paid.

4. Is your revenue exclusively card-based?

MCAs are specifically designed for businesses with strong card transaction volumes. If a significant portion of your revenue comes from bank transfers, cheques, or cash, a holdback on card sales only captures part of your trading activity. A revolving credit facility is not restricted by revenue type.

5. Do you meet the criteria for traditional credit?

MCAs are often accessible to businesses that have been declined for traditional credit, partly because the repayment mechanism (holdback on future card sales) provides the provider with natural security. If your business meets the criteria for a revolving credit facility with an FCA registered lender, the cost and flexibility comparison generally favours the revolving credit product. If you have been declined for traditional credit, your options are more limited and an MCA may be the most accessible route.

What this means in practice: the cost of staying with an MCA

One scenario worth examining is a business that has used MCAs repeatedly and is now assessing whether the cumulative cost justifies staying with the product.

Example: recurring MCA use over 2 years

A hospitality business takes 4 successive MCAs over 2 years. Each advance is approximately £25,000 with a factor rate of 1.28. Total cost per advance: £7,000. Total cost across 4 advances: £28,000.

Each advance also carries a holdback period averaging 10 to 12 months. For most of a 2-year period, a proportion of every card transaction has been going to an MCA provider.

A revolving credit facility of £50,000 over the same period, with draws and repayments aligned to the same working capital needs, would have carried a total interest cost substantially lower in most scenarios, because early repayments reduce interest and the facility does not apply a fresh fee every time a new draw is made.

The exact difference depends on specific rates, which vary by business and lender. The structural point is that repeated MCA use compounds total cost in a way that a revolving facility does not.

How Juice Flex fits in

Juice Flex is a revolving credit facility designed for UK SMEs, from £50,000 to £1M (subject to status and lending criteria).

It is built around the principle that working capital should be flexible and transparent. You draw what you need when you need it, pay interest on what you have drawn, and repay on agreed terms. The facility is always there for the next draw without a new application.

Key features:

Juice Flex is not the right product for businesses that need funding within 24 hours and cannot wait for a credit application, or for businesses that do not meet the lending criteria. If you are in that position, the MCA route may be more appropriate for your current situation.

For businesses that do qualify, the combination of cost transparency, repayment predictability, and the revolving structure makes it worth comparing against your current or proposed MCA terms.

A note on switching mid-MCA

If you are currently mid-way through an MCA repayment and considering switching, the calculation is more complex.

You still owe the full remaining balance of your MCA, because the total agreed amount is fixed regardless of how much you have repaid to date. A revolving credit facility would sit alongside that existing obligation, not replace it.

In this case, the right approach is to finish repaying the current MCA before drawing on a new facility, unless the revolving credit facility is large enough to cover the MCA settlement and your business cash flow can comfortably support both in the interim.

Some MCA providers will offer a settlement figure that is less than the outstanding total in certain circumstances. It is worth asking directly, but do not assume early settlement is available or discounted.
