Merchant Cash Advance Explained: How It Works for UK Businesses

A merchant cash advance (MCA) is a form of business funding where a provider advances a lump sum in exchange for a percentage of future revenue. Unlike a traditional loan, an MCA is repaid through daily or weekly deductions from card sales, and in some structures wider revenue or bank turnover, not through fixed monthly instalments.

This guide explains how MCAs work for UK businesses, the cost structure, when they make sense, and how they compare to alternatives.

How a Merchant Cash Advance Works

‍

The provider advances a lump sum — say, £50,000 — which the business receives upfront. The business agrees to repay a higher total amount — say, £67,500 — determined by a factor rate (in this case, 1.35). Repayment is collected automatically as a fixed percentage of daily card transactions or bank deposits, known as the holdback rate.

Because repayment scales with revenue, there is no fixed monthly payment. In a slow month, less is collected. In a strong month, more is collected. The advance is considered repaid once the agreed total has been collected.

‍

The Factor Rate Explained

‍

MCAs don't use an interest rate in the traditional sense. They use a factor rate — a multiplier applied to the advance amount to calculate total repayment.

The factor rate is fixed at the outset. Critically, it does not reduce if you repay faster. Whether the advance is repaid in 90 days or 12 months, the total repayment remains the same. This makes fast repayment expensive on an annualised basis.

These are illustrative examples only. Actual terms depend on the lender and your business circumstances.

Holdback Rate and Repayment Speed

‍

The holdback rate is the percentage of daily revenue deducted for repayment. Holdback rates vary by provider and business, with typical ranges from low single digits up to around 20% of daily card or bank deposits.

A higher holdback rate repays the advance faster, which frees up the total repayment obligation sooner — but does not reduce the total cost. A lower holdback rate extends the repayment period and may improve day-to-day cash flow, but the total owed remains the same.

Who Offers MCAs in the UK

‍

Many UK MCA providers require:

• A minimum period of trading (typically 6–12 months)
• A minimum monthly card revenue or bank turnover threshold
• A UK-registered business

‍

When an MCA Makes Sense

‍

MCAs may be appropriate when:

• The business has strong card revenue but limited credit history or trading tenure
• Speed is critical — MCA approvals are typically faster than conventional underwriting
• The business does not qualify for a revolving credit facility or term loan
• The capital need is a one-off event (not a recurring working capital requirement)

If your business qualifies for a revolving credit facility, it may be more cost-efficient for recurring needs, particularly where you draw and repay regularly. MCAs carry a higher implied cost, particularly when repaid quickly, because the factor rate is fixed regardless of repayment timeline.

‍

Key Takeaways

‍

• An MCA advances a lump sum repaid through daily revenue deductions, using a factor rate rather than an interest rate
• The factor rate is fixed — repaying faster does not reduce total cost
• MCAs are well-suited to high card-revenue businesses that need fast access to capital but have limited credit history
• For businesses with recurring working capital needs, a revolving credit facility can be more cost-efficient, depending on rates, fees, repayment speed, and usage.
