Factor rate vs interest rate
A factor rate and an interest rate are not the same thing, and treating them as interchangeable costs owners real money. Here is exactly how they differ and how to compare them on the same axis.
This article is educational and is not an offer of credit.
Key takeaways
- A factor rate is a flat multiplier; an interest rate is an annualized percentage that accrues over time.
- Factor rates price merchant cash advances; interest rates and APRs price loans.
- A factor rate is fixed at signing and does not compound, so a running balance never grows.
- Paying off an advance early does not reduce the flat total unless the agreement includes a discount.
- To compare the two fairly, convert the factor rate to an APR-equivalent, which is an estimate for comparison only.
Two ways to price money
When you borrow with a loan, you pay an interest rate. When you take a merchant cash advance, you pay a factor rate. They both describe the cost of capital, but they are built on different mechanics, and that is why they cannot be compared at face value.
The core reason is structural. A loan is money lent to you that you repay with interest. An advance is the purchase of a portion of your future receivables, so it is not a loan at all. That single distinction drives every difference that follows.
How an interest rate works
An interest rate is an annualized percentage applied to a balance. As you carry the balance, interest accrues, and most loans amortize, meaning each payment covers some interest and some principal. The longer you hold the money, the more total interest you pay, all else equal.
Loans such as a business line of credit and an SBA 7(a) loan are quoted this way, usually as an APR. An APR rolls the interest rate and certain fees into one annual figure so you can compare loans on a common scale. Time is baked in, which is exactly what makes an APR useful.
How a factor rate works
A factor rate is a flat multiplier, usually between about 1.1 and 1.5. You multiply your advance amount by it once and the result is your total payback, locked in at signing. There is no annual percentage, no accrual, and no compounding.
Stay with our worked example. A $50,000 advance at a 1.40 factor means a total payback of $70,000 and a flat cost of $20,000. That $20,000 does not grow if the term runs long, and it does not shrink on its own if you finish early. It is a fixed price for fast, revenue-based access to capital. You can see the full breakdown for any amount in the MCA calculator.
The differences side by side
Put the two next to each other and the contrast is clear:
- Form: a factor rate is a decimal multiplier like 1.40; an interest rate is an annual percentage like 12 percent.
- Accrual: an interest rate accrues on a balance over time; a factor rate is applied once and stays flat.
- Compounding: interest can compound; a factor rate never does.
- Effect of time: more time means more interest on a loan, but the factor-rate total does not change with time.
- Effect of early payoff: paying a loan early usually saves interest; paying an advance early does not cut the flat total unless a discount is in the agreement.
- What it prices: factor rates price merchant cash advances; interest rates and APRs price loans.
Why you cannot compare them directly
Here is the trap. A 1.40 factor and, say, a 14 percent APR can look like they are in the same neighborhood, but they are worlds apart. The factor rate already represents your entire cost, while the APR is an annual figure. Comparing the bare numbers tells you almost nothing.
To compare honestly, you have to put the advance on the same axis as the loan by converting the factor rate to an APR-equivalent. That annualizes the flat cost over the repayment term. In our example, the $20,000 cost is about 40 percent simple, but repaid over roughly 12 months of daily remittances it works out to about 71 percent on an APR-equivalent basis. The APR-equivalent is an estimate built only for comparison, not a contractual APR, because an advance is not a loan. The math is laid out in how to convert a factor rate to an APR-equivalent and in our how we calculate true APR methodology.
Which one is right for you
Neither pricing model is good or bad by itself. A loan quoted in APR is usually cheaper over time when you qualify and can wait for approval. An advance priced with a factor rate is built for speed and weighs your revenue more than your credit, which is why it can fund quickly when a loan cannot.
The honest move is to convert the advance to an APR-equivalent and then weigh it against any loan you actually qualify for. Run your factor rate, amount, and term through the free factor rate calculator to see the APR-equivalent, read our cornerstone on merchant cash advance cost, and if a lower-cost loan fits your timeline, weigh it carefully.
