Factor Rates Explained: Why a 1.4 on a Cash Advance Isn't 40% Interest

When a funder quotes you a factor rate of 1.4 on a merchant cash advance, the number is designed to sound gentle. It isn't a percentage, it isn't an interest rate, and it doesn't behave like either one. It's a flat multiplier applied to the amount you receive, and understanding exactly how it works is the difference between an informed decision and an expensive surprise.

What a factor rate actually is

A merchant cash advance (MCA) is not legally a loan. It's the purchase of a slice of your future revenue at a discount. Because it isn't structured as a loan, it usually doesn't carry a stated interest rate. Instead, the cost is expressed as a factor rate — typically somewhere between 1.1 and 1.5.

The math is simple, which is part of the problem. You multiply the amount advanced by the factor rate to get your total repayment amount:

• Advance amount: $50,000
• Factor rate: 1.4
• Total you repay: $50,000 × 1.4 = $70,000
• Cost of the money: $20,000

That $20,000 is fixed the moment you sign. It does not shrink. It does not amortize. There is no outstanding balance that interest accrues against day by day — there is only a fixed dollar amount you owe and a schedule of payments pulling it out of your account.

Why "it's basically 40% interest" is wrong

Business owners see a 1.4 factor and mentally translate it to "40% interest." It's an understandable shortcut, and it dramatically understates the true cost. Interest on a normal loan is charged against a declining balance over time. If you borrow $50,000 at 40% APR and pay it down over a year, you never pay 40% of the full $50,000 — you pay interest only on what's still outstanding, which drops with every payment.

A factor rate doesn't work that way. You owe the full $20,000 cost regardless of how quickly you repay. That means the effective annualized cost depends entirely on the term — and MCA terms are short, often just a few months.

The term is what makes it expensive

Here's the mechanism that catches people. Because the cost is fixed, paying an advance off faster makes the annualized rate higher, not lower. You're paying the same $20,000, just over less time.

Consider the same $50,000 advance with a $70,000 payback:

• Repaid over 12 months, the effective APR lands in the high double digits.
• Repaid over 6 months, that same $20,000 cost roughly doubles as an annualized rate.
• Repaid over 4 months — common for daily-remittance advances — the annualized cost climbs into the triple digits.

Short-term advances at typical factor rates routinely translate into APRs well above 50%, and often far higher, when you annualize the fixed cost over a term measured in months. The factor rate hides this entirely, because 1.4 is the same 1.4 whether the term is four months or fourteen.

Daily and weekly payments compound the drain

Most MCAs collect through fixed daily or weekly ACH withdrawals, or by holding back a percentage of your card sales. A fixed daily debit doesn't flex with a slow week. If sales dip but the withdrawal stays the same, the advance is consuming a larger share of the cash actually coming in the door. This is why an advance that looked survivable on paper can quietly starve payroll and rent within a couple of months.

Where the extra costs hide

The factor rate isn't always the whole story. Before you compare offers, get every one of these in writing:

• Origination or underwriting fees. A percentage skimmed off the top means you receive less than the advance amount but still repay the full factored total. See our breakdown of the gap between approved and deposited.
• The remittance structure. Fixed daily debit versus a true percentage of sales changes your real cash-flow exposure dramatically.
• The reconciliation clause. Some contracts promise to adjust withdrawals down if revenue falls — but only if you formally request it, submit documentation, and the funder agrees. Read exactly how that process works before you rely on it.
• Stacking restrictions. Many MCA agreements prohibit taking a second advance. Ignoring that clause can trigger a default on the first — the core risk we cover in loan stacking and second-position default.

How to convert a factor rate to a number you can compare

You can't compare a 1.4 factor rate to a bank line quoted at prime-plus without doing some conversion. A rough, honest way to think about it:

• Find the total cost. (Factor rate − 1) × advance amount. A 1.4 on $50,000 is a $20,000 cost.
• Find the cost as a percentage. $20,000 ÷ $50,000 = 40% — but that's the cost over the life of the advance, not per year.
• Annualize it. Divide that percentage by the term in months, then multiply by 12. A 40% cost over a 6-month term is roughly 80% on an annualized basis — and that's before fees.

This is a simplified estimate, not a lender-grade APR calculation, which also accounts for the timing of each payment. But it gets you close enough to see the truth: the shorter the term, the higher the real annual cost of the same factor rate.

The disclosure laws catching up to this

Regulators have recognized that a factor rate obscures the real price. Several states now require commercial-financing providers, including many MCA funders, to disclose a real annual percentage rate and total dollar cost before you sign. California's commercial financing disclosure regulations, administered by the Department of Financial Protection and Innovation, and New York's Commercial Finance Disclosure Law both require APR-style disclosures on many small-business financing offers. If you're in a state with these rules, you're entitled to see the annualized cost in plain numbers — ask for it. Our overview of the states that force real APR disclosure covers where these protections apply.

The takeaway

A factor rate is a flat multiplier, not an interest rate. The cost is locked in the day you sign, it doesn't amortize, and paying faster doesn't save you a dollar. To judge whether an advance is reasonable, convert the factor rate into a total dollar cost and then annualize it over the actual term — and demand any legally required APR disclosure. When you run those numbers, a 1.4 that looked like "40%" often reveals itself as a triple-digit annualized cost. That's not a reason to never use an advance; short-term, fast capital has its place. It's a reason to price it honestly against every other option before you commit your future revenue to it.
