Merchant cash advance explained: mechanics, cost and who qualifies

What a merchant cash advance actually is

A merchant cash advance is the purchase of a fixed amount of a business's future receivables at a discount. The funder pays a lump sum today and collects an agreed larger total over time, taken either as a percentage of daily or weekly card sales, or as a fixed debit from the business bank account.

The legal structure matters because it explains everything else about the product. An MCA is generally structured as a purchase, not a loan. That's why it's priced with a factor rate rather than an interest rate, why there's typically no fixed maturity date in the way a term loan has one, and why the qualification criteria look almost nothing like a bank's.

It's also why the product attracts strong opinions. Advances are fast and accessible to businesses banks won't touch, and they're expensive. Both things are true simultaneously, and anyone telling a merchant only one half of that is doing them a disservice.

The mechanics, with numbers

Say a funder advances $50,000 at a factor rate of 1.35.

• Total repayment: $50,000 × 1.35 = $67,500
• Cost of capital: $17,500
• If collection is a fixed daily ACH over roughly 12 months (about 250 business days): around $270 per business day
• If collection is a 12% holdback on card sales and the business does $70,000 a month in card volume: about $8,400 a month, repaying in roughly 8 months

Notice what changes between those two collection methods. The fixed ACH is predictable and unforgiving — the same amount comes out whether it was a good week or a terrible one. The holdback flexes with revenue, so a slow month automatically means smaller payments and a longer term. For a seasonal business, the holdback structure is meaningfully safer.

Factor rate versus APR

These are not the same thing and conflating them causes real harm. A factor rate of 1.35 is not 35% interest. Because the money is repaid over a short period, the annualised cost is substantially higher than the factor rate suggests.

Rough intuition: repaying $67,500 on $50,000 over twelve months, with the balance declining throughout, produces an effective annualised cost well into the high double digits. Compress the same repayment into six months and it roughly doubles again. The shorter the term, the higher the effective annual cost of the same factor rate — which is counterintuitive to most merchants, who assume paying it off faster saves money. With a fixed factor, early repayment usually doesn't reduce the total owed unless the agreement specifically provides for it.

Some states now require disclosure of an estimated APR or similar comparison metric on commercial financing. That's a good development for merchants and something brokers should be across.

Who qualifies

Underwriting reads the bank account, not the credit report. The common screening baseline:

• 6+ months in business. A near-universal floor. Some funders will look at four to five months with exceptional deposits; most won't.
• $10,000–15,000+ in monthly deposits. Below this the advance is too small to be economic for anyone.
• Deposit consistency. Ten or more deposits a month across the account beats three lumpy ones totalling the same amount. Consistency signals ability to service a daily or weekly collection.
• Low negative-day count. Repeated NSF or negative balance days in the last three months is the most common reason a superficially fine file gets declined.
• Manageable existing positions. Zero or one is clean. Two is workable with the right funder. Three or more is usually a distress signal.
• Credit: much less important than you'd expect. Many funders will work with scores in the 500s. Deposit behaviour carries the weight.

Typical advance sizing runs roughly 50–150% of average monthly deposits, though this varies considerably by funder, industry and position count.

Position stacking, and why it matters

"Stacking" means taking a second, third or fourth advance while earlier ones are still being repaid. Each position takes its own daily or weekly bite out of the same bank account.

The arithmetic gets ugly quickly. A business servicing three advances at $270, $180 and $150 a day is losing $600 a business day — around $12,000 a month — before rent, payroll or inventory. If that business is doing $60,000 a month in deposits, a fifth of its gross revenue is going to advance repayment. There is a point past which no operating business survives that, and merchants reach it faster than they expect because each individual advance felt manageable in isolation.

Many funder agreements restrict or prohibit stacking. From a broker's perspective, position count is one of the most important qualification questions there is — and a merchant asking for money to make payments on an existing advance is describing a debt spiral, not a funding need.

MCA versus a term loan or line of credit

When an advance is the wrong product

This section exists because most content on this subject skips it. An advance is the wrong choice when:

• The money is to service existing debt. Borrowing to pay borrowing is a spiral with a fixed ending.
• The business is shrinking rather than temporarily squeezed. An advance bought against future receivables assumes future receivables. If the trend is down, the collection will strangle the business faster than the capital helps it.
• The need is long-term. Buying a building or funding a three-year expansion with 9-month money is a mismatch. Expensive short capital should fund something that returns quickly.
• The business qualifies for cheaper capital and simply hasn't tried. If a bank or SBA product is realistically available and the timeline permits, it's cheaper by a wide margin.
• The return doesn't beat the cost. If $50,000 costs $17,500 and the use of funds generates $10,000 of additional margin, the merchant has paid $7,500 for the privilege of being busier.

The honest test is a single question: does what this money unlocks produce more than what the money costs, within the repayment window? Where the answer is clearly yes — a piece of equipment that lets you take a contract, inventory ahead of a season you can forecast, floating a job that's already signed — the advance is a reasonable tool. Where the answer is unclear, it usually isn't.

The funding process end to end

1. Application and statements. A one-page application plus three to six months of business bank statements. Statements are the whole game — everything else is administrative.
2. Underwriting. Average monthly deposits, deposit count, average daily balance, negative days, existing positions, industry. Typically 24–72 hours.
3. Offer. Advance amount, factor rate, total payback, collection method and frequency, and any fees. Read the fees; origination or administrative charges materially change the effective cost.
4. Signature and verification. Agreement executed, banking verified, sometimes a brief verbal confirmation call with the owner.
5. Funding. Usually one to three business days after signing.
6. Collection begins. Typically the next business day.

The bottleneck is almost never underwriting. It's the merchant taking a week to locate their statements — which is exactly why, when I'm qualifying merchants by phone, the statement request goes out while they're still on the call.

If you're a broker who wants that screening done before a file reaches your closers, that's the job I do: MCA cold calling and merchant qualification, with deposits, time in business, positions and negative days checked on the first call.
