Is a factor rate the same as an interest rate?

No. An interest rate is charged on the balance you still owe over time. A factor rate is a fixed multiplier on the amount advanced, so the total cost is set on day one regardless of how the balance falls.

Does paying off a factor-rate advance early save money?

Often it does not. Because the total payback is fixed, paying early usually means paying the same cost sooner, unless your agreement includes an early-payoff discount. Ask before you sign.

How do I convert a factor rate to APR?

You need the amount advanced, the factor rate, how long you will take to repay, and how often you pay. The APR is the rate at which those payments equal the amount you received. The calculator on this page does the math; treat the result as an estimate that excludes fees.

APR vs. factor rate: how to compare the real cost of financing

Some offers quote an APR and others quote a factor rate. They measure different things, and reading one as the other is one of the most expensive mistakes in small-business financing.

WithFunded Academy · Lesson 2 of 16 · 4 min read · Updated November 2026

Key takeaways

APR is a yearly rate on the balance you still owe. A factor rate is a fixed multiplier on the amount you receive.
A factor rate looks small because it ignores time. Repaid over months, the same cost is a much higher APR.
For the same factor rate, a shorter payback period means a higher APR.
Compare offers on total payback, payment size and frequency, and APR together.

Two ways to quote a price

APR (annual percentage rate) is the yearly cost of borrowing, applied to the balance you still owe. As you pay the balance down, the interest shrinks with it. Term loans, lines of credit, SBA loans, and equipment financing are usually quoted this way.

A factor rate is a multiplier on the amount you receive. A $50,000 advance at a 1.25 factor means you repay $62,500 in total, a $12,500 cost of capital, whatever the payment schedule. Working capital advances are often quoted this way.

Why a 1.25 factor is not 25% interest

Two things separate them. First, a factor-rate advance is usually repaid in well under a year, so the cost is packed into a shorter time. Second, you start repaying right away, so you do not have use of the full amount for the full period.

Take that same $50,000 at 1.25, repaid weekly over 9 months. That is 39 payments of about $1,603. Expressed as an annual rate on the money you actually had in hand, it works out to roughly 60.6% APR.

Same 1.25 factor, repaid weekly over	Total payback	Approximate APR
6 months	$62,500	89.9%
9 months	$62,500	60.6%
12 months	$62,500	45.7%

Equal weekly payments, no fees. WithFunded calculation; illustrative factor rate, not a quote.

The dollars owed never change. The annual rate does, because you are paying the same cost for less time with the money.

Factor rate to APR converter

Turn a factor-rate offer into an approximate APR so you can set it beside a loan or line of credit.

Amount advanced$ Factor rate Months to repay Payment schedule

Approximate APR60.6%

Total payback: $62,500
Cost of capital: $12,500
Each payment: $1,603

Assumes equal payments and no fees. An origination fee raises the APR further; so does repaying faster than planned on a fixed-fee product. Estimates for learning only. Not an offer, a quote, or financial advice.

When a higher cost can still make sense

A high APR is not automatically a bad decision. If $50,000 today lets you take a job or buy inventory that returns far more than the $12,500 it costs, and nothing cheaper can arrive in time, the math can work. Judge it in dollars: what the money costs against what it earns. The lesson on borrowing to grow shows how.

What rarely works is using short, expensive capital for a long-term need, or renewing it repeatedly to cover ongoing losses.

How to compare two offers quoted differently

Total payback in dollars. The one number every offer has.
Payment size and frequency. A daily or weekly payment hits cash flow differently from a monthly one.
Approximate APR. Convert the factor-rate offer with the calculator above. Some states, including California and New York, require providers to disclose an APR or estimated APR on many small-business financing offers.
Fees. Origination or underwriting fees are often deducted from what you receive, which raises the real cost.
