Factor Rate vs. APR: How to Compare the Real Cost of Business Funding

When you compare two funding offers, you'd assume you're comparing like with like. Often you're not. One offer quotes an APR, the other quotes a factor rate, and they measure cost in completely different ways. If you don't convert them to the same scale, you can easily pick the more expensive option while thinking you got the better deal.

Here's how each one works, why the difference matters, and how to compare them honestly.

What an APR actually measures

APR — annual percentage rate — is the cost of borrowing expressed as a yearly percentage, including interest and most fees. The key word is annual: APR accounts for time. A 30% APR means roughly 30% of the balance per year, so paying the loan off faster genuinely costs you less in total interest.

Term loans, lines of credit, and most bank products quote APR. It's the standard that lets you line up two loans side by side and see which is cheaper.

What a factor rate measures

A factor rate is a flat multiplier — usually somewhere around 1.2 to 1.5 — applied to the amount advanced. You multiply the advance by the factor to get your total repayment, and that number doesn't change no matter how the loan plays out.

A merchant cash advance is the product you'll most often see quoted this way. Take a $20,000 advance at a 1.3 factor rate: you repay $20,000 × 1.3 = $26,000. The $6,000 cost is fixed the moment you sign.

That fixed-cost nature is the whole catch — and it's where factor rates and APR diverge in a way that matters.

Why the difference is so easy to misread

A factor rate of 1.3 sounds like "30%," and 30% sounds comparable to a 30% APR loan. It isn't — usually not even close. Two reasons:

1. A factor rate ignores time. APR is annualized; a factor rate isn't. If you repay that $26,000 over six months instead of a year, you're paying the same $6,000 fee in half the time — which roughly doubles the effective annual cost. The shorter the repayment window, the higher the real APR climbs, even though the factor rate on paper never moves. A 1.3 factor repaid over a few months can translate to an effective APR well into the high double or even triple digits.

2. Paying it off early doesn't save you money. With an APR loan, paying early saves interest. With a factor rate, the cost is baked in — pay off that $26,000 in three months instead of twelve and you still owe the full $6,000 fee. So the "fast" funding can quietly become the most expensive funding per dollar borrowed.

How to compare them on the same scale

The fix is simple: convert everything to APR before you decide. The factor rate alone tells you the total cost, but not the cost relative to time — and time is exactly what determines whether one offer beats another.

A rough way to sanity-check a factor-rate offer:

1. Find the total cost: advance × factor − advance. ($20,000 × 1.3 − $20,000 = $6,000.)
2. Note the repayment term in months.
3. Recognize that the shorter that term, the higher the true annualized cost — a $6,000 fee over 6 months is far more expensive per year than the same fee over 18 months.

You don't have to compute the exact APR by hand. The honest move is to ask the funder for the APR-equivalent in writing, and to be wary if they'll only quote the factor rate. A reputable provider can tell you the effective APR; reluctance to is a flag.

When a factor-rate product still makes sense

None of this means factor-rate funding is always a bad deal — it means you have to see it clearly. A merchant cash advance can be the right call when speed and easy approval matter more than price, or when the funding generates more value than it costs. We cover that tradeoff in detail in our breakdown of whether an MCA is worth it.

But if you qualify for an APR-based product — a business line of credit, a working capital loan, or a term loan — those are usually cheaper, and comparing their APR to a converted factor rate is the only way to prove it to yourself. The point isn't to avoid factor rates. It's to never compare a factor rate and an APR as if they're the same number, because they aren't.

The bottom line

A factor rate tells you what you'll pay in total. An APR tells you what you'll pay relative to time. Speed-focused products use factor rates partly because the headline number looks smaller than the equivalent APR — so the burden is on you to convert before comparing. Ask for the APR, do the rough math, and judge every offer on the same scale.
