Merchant cash advance vs business loan: which fits?

Owners often compare these two products because they end up in the same lender shortlists. Both can deliver £25,000 to £250,000 within a week, both can be approved without property security, and both are widely advertised. But the underlying mechanics are different enough that picking the wrong one can cost the business 20 to 40 per cent more than it needed to. This guide breaks down the comparison the way an experienced finance broker would.

How each product is structured

Merchant cash advance

An MCA is technically not a loan. The lender purchases a slice of your future card or platform takings. You receive an agreed lump sum upfront, and you repay a fixed total — for example £130,000 against £100,000 advanced — by handing over a percentage of every card transaction until the total is cleared. There is no fixed term. If sales slow, repayments slow with them; if sales accelerate, the advance is cleared faster. Costs are quoted as a "factor rate" (e.g. 1.30) rather than an APR.

Unsecured business loan

An unsecured business loan is a traditional debt product. You borrow a fixed amount over a fixed term — typically 6 months to 5 years — and repay equal monthly instalments at a stated interest rate. There is no link to sales. The lender weighs trading history, turnover, profitability, director credit and affordability. Personal guarantees are usually required from directors on facilities above £25,000.

Speed and decision style

An MCA can fund within hours where the lender already has visibility of your card or platform data — Shopify Capital, Square Loans, SumUp, PayPal Working Capital and partner-led providers like YouLend and Liberis sit in this group. Decisions are largely automated against transaction history.

An unsecured loan from a fintech such as iwoca or Funding Circle can also fund inside 24 to 72 hours, but the underwriting involves bank statements, accounts and director credit checks. Bank-route loans from NatWest, Lloyds and similar high-street providers can take two to six weeks.

Eligibility differences that matter

• MCAs generally accept 3 to 6 months of card/platform processing. Most unsecured loans require 12 months minimum, often 24.
• MCA underwriting is dominated by sales volume. Loan underwriting is dominated by accounts, affordability and director credit.
• MCAs are accessible to businesses with minor adverse credit. Most loans want clean personal credit on directors.
• Loans suit B2B businesses, professional services and any model without card revenue. MCAs only fit if you process meaningful card or platform sales.

Cost: how to compare like for like

This is where buyers get caught. An MCA factor of 1.20 on £100,000 means you repay £120,000 — sometimes quoted as a "20 per cent fee". But the effective annual cost depends on how fast you repay. Clear the advance in 6 months and the implied annualised cost is roughly 40 per cent APR; clear it in 18 months and it is closer to 14 per cent APR. The fixed-fee structure means there is no interest saving from paying early.

A business loan with a 12 per cent representative APR on £100,000 over 3 years costs roughly £19,500 in total interest. Crucially, paying it off early saves interest. If your business has the trading history and credit to qualify for a loan, a loan is typically cheaper than an MCA on a like-for-like timeframe.

When an MCA is the right shape

• A Shopify-led DTC brand with £80k a month of platform sales, short trading history and no formal accounts yet.
• A high street salon with £25k a month of card sales wanting a fast £30k for a refit.
• A hospitality business with seasonal swings that wants repayments that flex with sales.
• Any merchant that needs cash inside 48 hours and already has live platform data.

When an unsecured loan is the right shape

• A B2B services business with 2 to 5 years of clean accounts and no card volume.
• Any borrower who wants budget certainty: fixed monthly repayments are easier to plan around than sales-linked draws.
• Larger amounts (£250k+) where MCA structures become uncompetitive on cost.
• Multi-purpose use cases: capex, hire, expansion — where the cash is not directly linked to a sales spike.

What about revenue-based finance?

Revenue-based finance from providers like Wayflyer and Outfund sits between an MCA and a loan. It is repaid as a share of revenue like an MCA, but the use case is usually growth funding for ecommerce — stock, marketing — rather than working capital. Cost is expressed as a flat fee on the amount drawn, and the product is geared to online merchants with strong unit economics. If you are a Shopify-led DTC brand, this is often the cheapest sales-linked option.

A simple decision framework

1. Do you process card or platform sales of £15k+ a month? If no, you are looking at a loan.
2. Do you have 18+ months of clean accounts and clean director credit? If yes, a loan is usually cheaper, subject to lender underwriting.
3. Do you need funds inside 48 hours? An MCA from your existing platform is usually fastest.
4. Are your sales seasonal or volatile? Sales-linked repayments reduce the stress of fixed instalments in slow weeks.
5. Is the amount over £250k? Loans, asset finance or invoice finance are usually better-shaped for larger tickets.
