MCA Factor Rate vs. APR: What Lenders Don’t Show You
A factor rate and an annual percentage rate describe the same advance in two very different languages. One is printed on your offer. The other tells you what the money actually costs.
What the offer shows
Factor rate. A flat multiplier. Looks like a small markup — “just 35%.”
What it actually costs
Estimated APR on a 6-month term. The same deal, annualized.
When a merchant cash advance (MCA) offer lands on your desk, the number that jumps out is the factor rate — something like 1.2, 1.35, or 1.49. It reads like a modest markup. Multiply your advance by it, and that is what you repay. Simple.
What the offer almost never shows is the annual percentage rate — the standardized measure that lets you compare the cost of any financing on equal footing. And the gap between the two is not small. A factor rate that looks like “35%” can translate into an effective APR well into the triple digits once you account for how quickly the money is repaid. This page explains why those two numbers diverge so sharply, how to convert one into the other, and what the difference means when you are deciding whether an advance is survivable — or whether an agreement you already signed deserves a closer look.
What a Factor Rate Actually Is
A factor rate is a fixed decimal multiplier applied one time to the amount you receive. It sets your total repayment and then never changes. There is no interest accruing, no balance compounding — just one flat figure baked in at signing.
The math is deliberately easy: advance amount × factor rate = total payback. On a $50,000 advance at a factor rate of 1.35, you repay $67,500. The $17,500 difference is the cost of the money. You can model this instantly with our factor rate calculator.
That simplicity is exactly what makes the factor rate persuasive — and misleading. It hides the one variable that matters most for cost: time. A factor rate says nothing about whether you repay over three months or twelve, and that single omission is where the real expense lives.
What an APR Actually Is
An annual percentage rate expresses the cost of financing as a yearly rate that accounts for both the fees and the timing of every payment. It is the measure federal law relies on so that borrowers can line up offers side by side. As the Consumer Financial Protection Bureau puts it, the APR is the interest rate plus the additional fees charged with a loan, expressed as a single annual percentage.
The reason APR matters for MCAs is the same reason it matters for payday loans. The CFPB uses a memorable example: a $15 fee on $100 looks like a 15% charge, but if it must be repaid in two weeks, that short term pushes the APR to nearly 400%. A flat fee spread over a short window is expensive precisely because the window is short. MCAs work the same way: the factor-rate markup is fixed, but the repayment period is compressed into months, so the annualized cost balloons.
Why the Two Numbers Diverge So Sharply
The entire gap comes down to speed of repayment. A factor rate is indifferent to time; an APR is defined by it. Convert between them and the same advance can look cheap or alarming depending only on the term.
Worked example — $50,000 advance, factor rate 1.35
Notice what changed between the two APR lines above: nothing except the term. The factor rate, the payback, and the dollar cost are identical. Yet the effective annual cost roughly doubles when the repayment window is cut in half, because daily or weekly withdrawals return the funder’s money faster. The shortcut approximation is (factor rate − 1) ÷ term in years, but because your outstanding balance shrinks with every ACH debit, a proper amortized calculation lands higher. Our MCA APR calculator runs that amortized math for you.
| Factor Rate | Total Payback | Cost of Capital | Est. APR — 6-month term | Est. APR — 12-month term |
|---|---|---|---|---|
| 1.15 | $57,500 | $7,500 | ~40% | ~22% |
| 1.25 | $62,500 | $12,500 | ~65% | ~37% |
| 1.35 | $67,500 | $17,500 | ~90%+ | ~50%+ |
| 1.49 | $74,500 | $24,500 | ~125%+ | ~70%+ |
Estimates assume amortizing daily/weekly repayment. The pattern — shorter term, higher APR at the same factor rate — holds regardless of advance size.
Why Lenders Show One and Not the Other
The reason is structural, and it is the same reason MCA disputes are so contentious. A merchant cash advance is documented as a purchase of future receivables, not a loan. Because it is framed as a purchase rather than credit, it has historically sat outside the federal Truth in Lending Act, which requires standardized APR disclosure on consumer loans. No loan, on this theory, means no required APR.
That is changing. A growing number of states now require APR-style cost disclosure for commercial financing, and enforcement of the underlying “is this really a loan?” question has intensified. We cover that shifting landscape in depth in our Merchant Cash Advance Litigation Trends Report and our state-by-state breakdown of MCA laws by state. But in much of the country, an MCA can still be presented to you using only the factor rate — which is precisely why understanding the conversion yourself is a form of self-defense.
Myth vs. Reality
How to Pressure-Test an Offer Before You Sign
- Convert the factor rate to an APR. Never evaluate an MCA on the factor rate alone. Run the numbers through the MCA APR calculator to see the annualized cost.
- Model the withdrawal you’ll actually feel. Cost is one thing; cash-flow survivability is another. Estimate the debit hitting your account with the daily payment calculator or the weekly payment calculator.
- Check what a percentage-of-revenue structure means for you. If your agreement uses a holdback rather than a fixed debit, the revenue holdback calculator shows how it scales with sales.
- Account for advances you already carry. A second or third advance compounds the burden fast. The stacking calculator models the combined pressure.
- Know your exit math. If you’re already in a difficult agreement, the settlement calculator estimates how a negotiated resolution compares with paying the full balance.

Already in an MCA that looks unsustainable?
If the APR you just calculated is alarming — or an advance you already signed is straining your cash flow, has triggered aggressive withdrawals, or has led to a lawsuit or frozen account — it may be worth having the contract reviewed.

What is the difference between a factor rate and an APR?
A factor rate is a flat multiplier applied once to the advance amount to set the total you repay; it does not change with time. An APR expresses cost as a yearly rate that accounts for how quickly you repay. Because most merchant cash advances are repaid in months rather than years, the same factor rate can translate into an APR many times larger.
How do I convert a factor rate to an APR?
Find the total cost first: multiply the advance by the factor rate, then subtract the advance amount. Measured against how long you actually take to repay, that cost produces the annualized rate. A rough shortcut is (factor rate − 1) ÷ term in years, but because daily withdrawals shrink the balance over time, an amortized calculation is more accurate. The MCA APR calculator does this for you.
Why don’t MCA lenders show an APR?
Merchant cash advances are structured as purchases of future receivables rather than loans, so historically they fell outside the federal Truth in Lending Act, which requires APR disclosure on consumer credit. A number of states now require APR-style disclosure for commercial financing, but in much of the country an MCA can still be presented using only a factor rate, which understates the annualized cost.
Is a lower factor rate always cheaper?
Not necessarily. A lower factor rate paired with a shorter repayment term can carry a higher effective APR than a higher factor rate repaid over a longer term, because the money is returned faster. Comparing offers requires looking at APR and daily or weekly payment burden, not the factor rate alone.
What is a typical MCA factor rate?
Factor rates commonly fall between roughly 1.1 and 1.5, though they vary by funder, risk assessment, and term. A factor rate of 1.3 on a $50,000 advance means $65,000 in total repayment. The annualized cost depends heavily on how short the repayment period is.
Does a high MCA APR mean the contract is illegal?
A high effective APR does not automatically make an agreement unlawful, because MCAs are framed as receivables purchases rather than loans. But when payments are fixed and any reconciliation right is illusory, regulators and courts have increasingly examined whether a particular agreement functions as a disguised, potentially usurious loan. Whether a specific contract is vulnerable is a fact-specific legal question for qualified counsel.
