MCA Factor Rates Explained: Converting to APR
A merchant cash advance uses a factor rate, not an interest rate, making true cost comparison difficult. Converting a factor rate to an APR reveals the annualised cost and allows direct comparison with term loans or revolving credit. The conversion depends heavily on how quickly you repay, which is driven by your card or bank turnover.
What a factor rate actually means
A factor rate is a simple multiplier applied to the advance amount to calculate the total repayment. If you borrow £50,000 at a factor rate of 1.30, you repay £65,000 in total regardless of how quickly that repayment occurs. The £15,000 difference is the cost of the advance, expressed as a flat amount rather than as an annual percentage.
This is fundamentally different from interest, which accrues over time. Because a factor rate carries no time dimension, two businesses borrowing at 1.30 but repaying over six months versus twelve months face very different annualised costs. The business repaying in six months pays the equivalent of a much higher APR, even though the total repayment figure is identical.
The conversion formula step by step
Converting a factor rate to an approximate APR requires you to estimate the repayment period, then apply a standard annualisation. The most common method used by UK brokers is to calculate the total cost of credit, divide by the advance amount to get a decimal cost, then annualise based on expected repayment duration.
The working is: total repayment equals advance multiplied by factor rate. Cost of credit equals total repayment minus advance. Decimal cost equals cost of credit divided by advance. Estimated APR equals decimal cost divided by repayment term in years. So a £50,000 advance at factor 1.30 repaid over nine months produces a cost of £15,000, a decimal cost of 0.30, and an approximate APR of 40% (0.30 divided by 0.75 years). Repaid over six months, the same advance approximates a 60% APR.
Why repayment speed drives the APR so sharply
Because the MCA provider collects a fixed percentage of your daily or weekly card receipts or bank settlements, businesses with higher turnover repay faster and therefore face a higher effective APR for the same nominal factor rate. A hospitality venue processing £80,000 per month will repay a £50,000 advance far sooner than a seasonal retailer processing £20,000 per month, yet both see the same total repayment figure on their agreement.
This asymmetry is one reason the FCA has encouraged greater disclosure standards around MCAs, though as of May 2026 most MCAs remain outside the Consumer Credit Act framework when advanced to limited companies. Borrowers should always model two scenarios: a faster repayment based on peak trading and a slower repayment based on a conservative trading estimate, to bracket the true APR range before signing.
Comparing MCA cost against a term loan at current rates
With the BoE base rate at 3.75% following the December 2025 decision, well-priced unsecured term loans for SMBs currently range from roughly 9% to 22% APR depending on credit profile, trading history and loan size. A factor rate of 1.20 repaid over twelve months equates to roughly 20% APR, which is broadly competitive with the upper band of unsecured term lending for businesses with moderate credit files.
However, a factor rate of 1.35 repaid over eight months produces an APR closer to 52%, which is materially more expensive than any conventional unsecured product available to the same borrower. The MCA may still be the right choice if the business cannot satisfy bank affordability criteria, needs funds within 24 to 48 hours, or has fluctuating revenue that makes fixed monthly loan repayments operationally risky. Cost alone does not determine suitability.
Holdback percentage and its effect on true cost
The holdback rate, sometimes called the retrieval rate, is the percentage of each day's card or bank receipts deducted to service the MCA. A typical range in the UK market is 10% to 20%. The holdback does not change the total repayment, but it directly controls how fast the advance is retired and therefore the effective APR.
Negotiating a lower holdback extends the repayment period and reduces the APR. A business expecting a slow trading quarter has a strong case to request a holdback of 10% rather than 15%, stretching a six-month repayment to nine months and reducing the approximate APR by a third. Some UK MCA providers also offer temporary holdback pauses during demonstrable revenue downturns, which further smooths the annualised cost calculation. Always request written confirmation of any agreed holdback adjustment before drawdown.
Regulatory disclosure and what to ask your provider
UK limited companies taking MCAs are not currently entitled to the same FCA Consumer Credit Act protections that apply to sole traders, meaning lenders are not required to quote an APR on business MCA agreements. However, the FCA's ongoing review of business lending disclosures may change this position, and several larger UK MCA providers now voluntarily disclose indicative APR ranges.
When evaluating an MCA offer, ask the provider for: the total repayment amount in pounds, the assumed repayment term used in their internal pricing, the holdback percentage, and any additional fees such as origination or administration charges. Armed with those four figures, you or your broker can complete the APR conversion above and compare the offer directly against alternative products. If a provider cannot or will not supply these figures clearly, that itself is relevant information.

Step-by-step
- Obtain the factor rate and advance amount from the MCA term sheet.
- Calculate total repayment: advance multiplied by factor rate.
- Calculate cost of credit: total repayment minus advance.
- Estimate repayment term in months based on your average monthly card or bank receipts divided into the total repayment figure.
- Convert term to years: repayment months divided by 12.
- Calculate approximate APR: cost of credit divided by advance, then divided by term in years.
- Compare the resulting APR against alternative products such as unsecured term loans, revolving credit facilities or asset finance before committing.
Example
A four-branch sandwich chain in the East Midlands was offered an MCA of £60,000 at a factor rate of 1.28, giving a total repayment of £76,800. Monthly card takings averaged £40,000 across all sites, implying a repayment period of roughly 1.92 months at a 10% holdback collecting £4,000 per month. Recalculating at a negotiated 12% holdback collecting £4,800 monthly stretched the term to 16 months and reduced the approximate APR from 174% to 21%, making the product genuinely competitive with unsecured term alternatives.
Frequently asked questions
Is APR a reliable comparison tool for merchant cash advances?
APR is a useful directional comparison but has limitations for MCAs because repayment is variable rather than fixed. A faster trading month accelerates repayment and raises the effective APR retrospectively. Use APR to compare MCA offers against each other and against conventional loans, but also consider operational fit: flexible repayment can be worth a higher annualised cost if your revenue is genuinely seasonal or unpredictable.
Do UK MCA providers have to disclose APR to limited companies?
Not currently. Most MCAs advanced to UK limited companies fall outside the Consumer Credit Act 1974, so lenders are not legally required to quote an APR. Some providers do so voluntarily. The FCA has signalled interest in improving SMB lending disclosure standards, but no mandatory regime was in force as of May 2026. Always ask for total repayment, fees, and assumed term so you can calculate APR yourself.
What factor rate range should a healthy UK SMB expect?
A UK SMB with at least 12 months of trading history, consistent card or bank turnover and no significant adverse credit should typically see factor rates between 1.15 and 1.35. Rates above 1.40 usually indicate elevated lender risk perception, either due to thin trading history, sector risk, or adverse credit markers. Hospitality and retail businesses often attract the most competitive rates due to predictable card-based revenue.
Can I repay an MCA early to reduce the total cost?
Unlike a loan, an MCA has no amortising interest, so early repayment does not reduce the total amount owed in most standard UK MCA agreements. You repay the full factor rate amount regardless of speed. A small number of providers offer early settlement discounts, typically reducing the outstanding balance by 5% to 10% if settled before 50% of the expected term has elapsed. Always check the specific agreement terms before assuming early repayment will save money.
How does holdback negotiation work in practice?
Holdback is usually proposed by the MCA provider based on your average monthly receipts, with the aim of retiring the advance within six to twelve months. You can negotiate a lower percentage, particularly if you can demonstrate seasonal revenue dips or show that the proposed holdback would create cash flow strain. Provide three to six months of bank or card processing statements to support your request. A written amendment to the agreement should confirm any agreed change.
