What Is a Factor Rate? | Factor Rate vs. Interest Rate

A factor rate is a flat multiplier — typically 1.1 to 1.5 — applied to a merchant cash advance to set the total amount you'll repay, regardless of how long repayment takes. A $50,000 advance at a 1.3 factor rate means $65,000 owed back, full stop. Unlike an interest rate, a factor rate doesn't accrue over time or reduce as you pay down the balance — which is exactly why it can look cheaper than it is.

Understanding this one number is the difference between accurately comparing an MCA to a loan and badly underestimating what it actually costs. For the full picture of how a merchant cash advance compares to other funding types, see the main hub.

Factor Rate vs. Interest Rate: The Core Difference

An interest rate (APR) accrues over time on a declining balance — pay it off faster, and you pay less total interest. A factor rate is a one-time multiplier fixed at signing — the total payback amount doesn't change whether you repay in 3 months or 15. That means the faster you repay an MCA, the higher your effective annualized cost turns out to be, which is the opposite of how loans work.

	Factor rate (MCA)	Interest rate (loan)
Applied to	Total advance, once	Outstanding balance, over time
Changes if repaid early	No — total is fixed	Yes — less interest accrues
Typical range	1.1–1.5	Varies widely by product
Annualized comparison	Requires conversion	Already annualized (APR)

How to Convert a Factor Rate to an Approximate APR

There's no single universal formula — the annualized cost depends heavily on the repayment period. As a rough illustration: a 1.3 factor rate repaid over 12 months lands at a meaningfully lower effective annual rate than the same 1.3 factor rate repaid over 4 months, because the same total cost is compressed into a shorter window. This is why two MCA offers with an identical factor rate can have very different real costs. Estimate your own numbers: merchant cash advance calculator.

Why Providers Use Factor Rates Instead of APR

Because most merchant cash advances aren't legally loans, they generally aren't subject to the same interest-rate disclosure rules as consumer or business loans in most states — which is part of why the factor rate format persists. Some jurisdictions have started requiring clearer cost disclosures for commercial financing; regulation in this space is evolving, so always ask a provider directly what disclosure they're required to give you. The Consumer Financial Protection Bureau and the Federal Trade Commission both publish general guidance on evaluating non-traditional business financing costs.

What Moves Your Factor Rate

Providers typically price factor rate based on time in business, monthly revenue and its consistency, industry risk, and credit profile. Stronger, more consistent sales generally earn a lower factor rate; see how does a merchant cash advance work for the full underwriting picture.
