A merchant cash advance is not a loan, and that distinction is the point of the product. Because it is structured as the purchase of future receivables rather than an extension of credit, it sits outside much of the regulation that governs lending — including, in many jurisdictions, the requirement to state an annual percentage rate.
The result is a financing product whose cost is genuinely difficult to compare against alternatives, sold to businesses that usually have not done the arithmetic. Doing the arithmetic is the whole of this article.
How the structure works
The provider advances a lump sum. In exchange, it takes a fixed percentage of daily card receipts until it has collected an agreed total.
That total is expressed as a factor rate — typically something like 1.2 to 1.5. A factor rate of 1.35 on an advance of 50,000 means repaying 67,500, collected as a percentage of daily takings until the full amount is recovered.
Two features are genuinely different from a loan. There is no fixed term — repayment takes as long as revenue takes. And the daily amount flexes with sales, so a slow week collects less. Both are real advantages for a business with volatile revenue, and they are the honest part of the sales pitch.
Why the factor rate conceals the cost
A factor rate of 1.35 reads like 35 percent. It is not comparable to a 35 percent interest rate, and the reason is that the cost is fixed at the outset while the repayment period is short.
Take the 50,000 advance repaid at 67,500. If daily collections retire it in six months, the business has paid 17,500 to use money for an average of roughly three months — because the balance declines throughout, the average outstanding is far below 50,000.
Annualised, that is a cost well into the triple digits in percentage terms. The precise figure depends on the repayment speed, but the direction is unambiguous: the shorter the repayment period, the higher the effective annual rate for the same factor rate.
This produces the product’s most counter-intuitive property. Strong sales make the financing more expensive. Faster collection means the same fixed cost is paid over a shorter period, raising the effective annual rate. A business that performs well after taking an advance is penalised for it.
The comparison that matters
To compare an advance against any other financing, convert it to an approximate annual rate:
- Total cost = (factor rate − 1) × advance amount
- Estimate the repayment period in months from the holdback percentage and realistic monthly card revenue
- Average outstanding balance is roughly half the advance
- Annual rate ≈ (total cost ÷ average outstanding) × (12 ÷ months to repay)
This is an approximation rather than a formal APR calculation, and it is close enough to make the decision. Run it before signing, not after — and run it at a realistic revenue estimate rather than the optimistic one used in the sales illustration, since a slower repayment lowers the annual cost but extends the drag on daily cash.
The stacking problem
The most serious risk is not the cost of one advance. It is what happens next.
An advance reduces daily cash immediately. A business that was short of cash before now has the same shortfall plus a daily deduction from takings. The most available solution is a second advance, frequently from a different provider — a practice called stacking.
Two advances mean two daily holdbacks. Combined, they can consume 20 or 30 percent of card revenue before wages, stock or rent. At that point the business is working principally to service the financing, and the mathematics do not recover on their own.
This is the mechanism by which the product does real damage, and it is a predictable consequence of using short-term expensive money for a structural shortfall rather than a timing gap.
When it is defensible
There are genuine cases. The test is whether the money funds something with a return that exceeds the cost, over a horizon shorter than the repayment period.
- Defensible: discounted inventory available now that will sell within the repayment window at a margin comfortably above the financing cost; emergency equipment replacement where the alternative is stopping trading; bridging a confirmed receivable with a known payment date.
- Not defensible: covering an ongoing operating deficit; paying another advance; funding growth that will not generate cash for a year or more.
Before accepting one, the alternatives are worth exhausting: a bank overdraft or line, invoice financing against specific receivables, supplier terms, or a business credit card — which at 25 percent annually is frequently far cheaper than an advance despite feeling more expensive.
The underlying question is almost always whether the business has a timing problem or a profitability problem. Expensive short-term money can bridge the first. It accelerates the second — which is why the cash conversion cycle is worth understanding before the situation becomes urgent, as we set out in cash flow management fundamentals for small businesses.
