Merchant Cash Advance True Cost: Convert the Factor Rate Before You Sign

Say a provider offers you $100,000 at a 1.35 factor rate, and the pitch makes it sound like 35%. This is the conversion that gives you the real number:

Total cost        = (Advance × Factor rate) − Advance + Fees withheld
Net cash received = Advance − Fees withheld
Quick annual cost ≈ (Total cost ÷ Net cash received) × (365 ÷ Term in days) × 2

That last line is a screening shortcut, and it's close enough to stop a bad decision. A merchant cash advance quoted at a 1.35 factor rate and repaid over about six months costs well over 100% a year, not 35%. The factor rate tells you how much you pay back. It says nothing about how fast you pay it back, and speed is what drives the annual cost.

The rest of this piece walks through the conversion on a hypothetical offer, explains why the shortcut multiplies by two, and shows what a renewal does to the math.

Why the factor rate looks cheaper than it is

An MCA provider buys a share of your future receipts. You get a lump sum today and repay a fixed total through daily or weekly debits, either a percentage of card sales or a fixed ACH amount.

A factor rate of 1.35 means you repay $1.35 for every $1.00 advanced. Owners naturally read that as "35% interest." But with a loan, 35% interest would be charged on a balance you hold for a full year. With an MCA, you start paying back the day after funding. On average, you only have about half the money for about half the term. Pay $35 for the use of roughly $50 for roughly three months and the annual rate is far above 35%.

That's also why the shortcut multiplies by two: it adjusts for the declining balance. It overstates the precise figure, by about 20 points in the example below, which is fine for a screen.

Converting a hypothetical offer, step by step

Assume a hypothetical $3M home-services company gets this offer:

• Advance: $100,000
• Factor rate: 1.35
• Origination and underwriting fees withheld at funding: $2,500
• Remittance: fixed weekly debit of $5,192 for 26 weeks

Step 1, total payback. $100,000 × 1.35 = $135,000.

Step 2, total cost. $135,000 − $100,000 + $2,500 = $37,500.

Step 3, net cash received. $100,000 − $2,500 = $97,500. Use this, not the face amount, because it's the money you can actually spend.

Step 4, quick screen. ($37,500 ÷ $97,500) × (365 ÷ 182) × 2 ≈ 154%.

Step 5, the precise figure. Solve for the weekly rate that makes 26 payments of $5,192 equal to $97,500 today. That rate is about 2.58% per week, or roughly 134% a year as a simple annual rate. Compounded, the effective annual cost is higher still.

Here's how payment speed changes the answer on the same $135,000 payback:

If remittance is a percentage of card sales, a strong sales month repays you faster and pushes the annual cost up. A slow month stretches the term and lowers it. Same contract, different cost, which is why the regulators below require an estimate rather than a fixed rate.

What disclosure rules now require

Two large states require MCA-style providers to show an annualized rate.

In New York, the commercial finance disclosure regulation, 23 NYCRR Part 600, requires a provider extending a specific offer to disclose the annual percentage rate, determined under the United States Rule or actuarial method in Appendix J of 12 CFR Part 1026. Sales-based financing uses either a "historical method" or an "opt-in method" to estimate it, and the threshold section applies the rules to offers of $2,500,000 or less.

In California, 10 CCR § 942, operative December 9, 2022, requires sales-based financing providers to estimate payments, term, and APR from an estimated monthly sales projection, accounting for split-rate changes, minimum payments, and reasonably anticipated true-ups.

If your business is in one of those states, ask for the disclosure and compare it with your own calculation. If you're elsewhere, ask anyway. A provider that can't or won't estimate the APR is telling you something.

The renewal trap

The most expensive part of an MCA is often the second one. Many providers offer to "renew" once you've repaid part of the balance. Look at what the renewal actually funds.

Hypothetically, say you've made 13 of 26 payments on the deal above, so $67,500 of payback remains. The provider offers a new $100,000 advance at the same 1.35 factor and $2,500 fee, with the remaining balance paid off from the proceeds.

You've taken on $135,000 of new payback to receive $30,000 of fresh cash. Part of the $67,500 you "paid off" was the unearned factor charge on the first advance, which the renewal effectively charges you again. Some contracts discount the remaining balance on early payoff; many don't. Read the early-payoff clause before you assume you'll get a credit.

Stacking, meaning taking a second advance from a different provider while the first is still being debited, compounds the problem. Two daily debits come out of the same deposits, and a dip in sales hits both.

An MCA usually shows up after a cash gap someone could have seen coming. Bennett's Leak Check takes 20 minutes, needs no documents, and is built to find where the gap starts: margin, collections, payroll timing, or tax payments.

When a merchant cash advance can still make sense

There are narrow cases where the cost is defensible:

• The return is fast and certain. If $100,000 of materials lets you finish a contract that releases a $160,000 milestone payment in six weeks, a high annual rate on a short hold may still leave you ahead. Model the actual dollars, not the rate.
• Every cheaper option is genuinely closed. Not "the bank is slow," but declined, with no line, no receivables to factor, and no owner capital.
• It's one advance, with an exit. You know which receipt pays it off and you won't need a renewal.

If none of those are true, the MCA is funding an operating shortfall, and that shortfall will still be there when the debits end. Fix the shortfall first.

Cheaper alternatives to check first

Before signing, price the same $100,000 through:

1. A bank line of credit. Even at a double-digit rate, interest on $100,000 drawn for six months is a fraction of $37,500. Availability depends on your receivables; the borrowing base guide explains how that's set.
2. Invoice factoring, if your customers are businesses that pay on terms. It's expensive, but usually far below MCA cost.
3. A term loan refinance of existing debt to lower monthly payments, if debt service is the pressure. Run it through a refinancing review so fees don't eat the saving.
4. Releasing trapped cash. Card processor reserves, slow collections, and early vendor payments can tie up more than the advance. Check whether your processor reserve is holding money you're about to borrow against.

Also read the guarantee. Many MCA agreements ask the owner to personally guarantee performance, even though the provider describes the deal as a purchase rather than a loan. The personal guarantee sizing method applies here too.

Three clauses that change the real cost

The factor rate is only one input. Before you trust any annual figure, find these in the agreement:

• Reconciliation. If remittance is a percentage of sales, the contract should let you request an adjustment when sales fall. Check how often you can ask, what documents you need, and how long the provider takes to respond. A fixed ACH with no workable reconciliation behaves like a short, very expensive loan.
• Minimum or fixed debits. A "percentage of sales" deal with a minimum weekly payment loses its flexibility exactly when you need it.
• Default triggers. Changing banks, blocking a debit, or a drop in deposits can be listed as defaults that accelerate the full remaining payback. Know which actions trigger that before a slow month forces your hand.

What to calculate before you sign

Take the offer and fill in four numbers: payback, fees withheld, net cash received, and the expected weeks to repay at your real sales volume. Run the shortcut, then ask the provider for its estimated APR. If the annual cost is above 60% and the money isn't tied to a specific, fast-paying receipt, decline and work the cash problem instead.
