Factor Rate vs. APR: What a Merchant Cash Advance Actually Costs You

A merchant cash advance (MCA) is usually priced with a factor rate, not an interest rate. That single difference is why so many business owners sign one without realizing how expensive it can be. A factor rate looks small and tidy — "1.40" feels almost like a discount — but it describes a fixed dollar cost, not an annual percentage, and the two are not the same thing.

This article walks through how a factor rate works, why it is not an APR, why the effective APR is usually much higher than a quick annualized estimate suggests, and what to ask a funder before you sign. (Not financial advice.)

How a factor rate works

A factor rate is a simple multiplier applied to the amount you receive. You multiply the advance by the factor to get your total payback:

Advance × Factor Rate = Total Payback

Here's an illustrative, entirely hypothetical example (your real numbers will differ):

• Advance amount: $50,000
• Factor rate: 1.40
• Total payback: $50,000 × 1.40 = $70,000
• Cost of the financing: $70,000 − $50,000 = $20,000

So in this hypothetical, you receive $50,000 today and repay $70,000 over the term. The $20,000 difference is the fixed cost of the advance. Factor rates commonly fall somewhere in a range above 1.0, and the exact figure depends on the funder, your business, and your perceived risk — treat the 1.40 above purely as a round number for the math, not a typical or quoted rate.

Repayment is usually collected automatically as a daily or weekly remittance — either a fixed amount or a percentage of your card sales (a "holdback") — until the full payback is satisfied.

Why a factor rate is NOT an APR

It's tempting to read "1.40" as "40% interest." It isn't, and the difference matters in both directions.

• An APR is an annualized rate. It expresses cost as a percentage per year, which lets you compare a 6-month product against a 3-year product on equal footing.
• A factor rate is a flat multiplier with no time built in. The $20,000 cost in the example is the same whether you repay over 6 months or 18 months — the factor doesn't change because the calendar does.

That's the trap. Because the dollar cost is fixed regardless of term, a factor rate hides the time dimension entirely. The shorter the repayment period, the more expensive that same fixed cost becomes in annualized terms. To compare an MCA against a term loan, a line of credit, or another advance, you have to translate the factor rate into something time-based.

You can estimate your own scenario with the MCA factor-rate calculator — plug in your actual advance, factor, and term rather than relying on the round numbers here.

A simple annualized-cost estimate

A rough, easy-to-compute way to put a factor rate on an annual footing is:

Estimated annualized cost ≈ (Factor − 1) ÷ (Term in years)

Using the hypothetical above with, say, a 12-month (1.0-year) term:

• Factor − 1 = 1.40 − 1.00 = 0.40 (a 40% total cost over the life of the advance)
• 0.40 ÷ 1.0 year ≈ 40% per year

If that same advance were repaid in 6 months (0.5 years) instead:

• 0.40 ÷ 0.5 ≈ 80% per year

Same factor, same $20,000 cost — but compressing the payback into half the time roughly doubles the annualized figure. This is the single most important thing to internalize: with a fixed factor, a faster payoff makes the financing more expensive on an annualized basis, not less.

Treat this formula as a back-of-the-envelope estimate, not a precise APR. It ignores compounding and fees, so it's a floor, not a ceiling.

Why the true APR is even higher than that

Here's the part that surprises people. The simple estimate above still understates the real cost, because it implicitly assumes you have the full advance the whole time. You don't.

With an MCA, you start repaying almost immediately — daily or weekly — against a fixed total. So your outstanding balance shrinks steadily from day one. By the midpoint of the term you may only have roughly half the original advance still in hand, yet you're paying the full fixed cost as if you'd kept all of it.

The way lenders and regulators compute a true APR accounts for that declining balance: the same dollar cost spread over a much smaller average outstanding balance translates into a substantially higher annualized rate. A few drivers push it up:

• Rapid amortization. Daily/weekly remittances mean your average balance is far below the advance amount, so the cost-per-dollar-actually-borrowed is high.
• Short effective terms. Many advances are repaid in months, not years, which (as shown above) inflates any annualized figure.
• Fees on top of the factor. Origination, underwriting, or servicing fees increase the true cost beyond what the factor alone implies.

The practical takeaway: a factor of 1.40 repaid quickly can correspond to an estimated APR well into the triple digits — often far higher than the naive "(factor − 1)" percentage. Any APR figure you see should be treated as an estimate that depends heavily on the actual repayment speed and fees, but the direction is consistent: the real APR is higher than the factor rate makes it look, frequently dramatically so.

Prepayment usually does NOT save you money

With a conventional interest-bearing loan, paying early saves you future interest. With most MCAs, it doesn't — because the cost is the fixed factor, not accruing interest.

If your payback is $70,000, you generally owe $70,000 whether it takes 18 months or 6. Paying it off early just means you hand over that same fixed total faster, which (per the math above) actually raises your effective annualized cost.

Some funders advertise a prepayment discount or a reduced factor for early payoff, but that is a specific, negotiated term — not the default. Don't assume it exists. Read the agreement and ask directly.

What to ask before you sign

Before agreeing to an advance, get clear answers — in writing — on:

• The total payback amount in dollars, not just the factor rate.
• The factor rate and exactly what it's applied to.
• All fees (origination, underwriting, servicing, ACH/processing) and whether they're inside or on top of the payback.
• The remittance: daily or weekly? Fixed dollar amount or a percentage holdback of sales?
• The expected term, and how the timeline changes if your sales rise or fall.
• An estimated APR, and whether prepayment reduces the total cost at all.
• Default and stacking terms: what happens if a remittance fails, and whether taking a second advance is permitted.

If a funder won't translate the deal into a total dollar cost and an estimated APR, treat that as a reason to slow down.
