What is a Factor Rate and How Is It Calculated?

A factor rate (also called a loan factor) expresses the percentage of a loan amount that you need to pay back. It’s commonly used in commercial financing offers (such as sales- or revenue-based financing) and merchant cash advances. Factor rates are typically expressed as a decimal figure between 1.1 and 1.5.

Below, you’ll learn more about what a factor rate is, how it operates, and how nonbank finance companies typically use factor rates to make money.

Key Points

•   Lenders may charge factor rates, which are expressed as decimals, on certain types of loan products instead of using traditional interest rates, which are expressed as percentages.

•   To calculate the total cost of your loan, simply multiply the loan amount by the factor rate and then add any additional fees the lender may charge.

•   Pros of factor rates can include fast funding times, less stringent credit requirements, and the relative ease of determining the total cost of the loan.

•   The main con of factor rates is that they’re typically a very expensive form of borrowing and can translate into annual percentage rates (APRs) of 70% or more.

Factor Rates Defined

What is a loan factor, also known as a factor rate? It’s a number typically used by nonbank finance companies to calculate some or all of your total costs on nontraditional commercial funding.

The following sales-based financing or revenue-based financing products usually come with a factor rate:

•   Inventory financing

•   Invoice factoring

•   Merchant cash advances (MCA)

•   Purchase order financing

But what is the loan factor exactly? Factor rates on a merchant cash advance typically range from 1.1 to 1.5, and the rate is used to calculate your repayment costs (not including any additional fees).

Factor Rates vs APR

It’s worth noting that MCAs and other sales-based financing products are typically expensive when compared with traditional small business loans. That’s because the total costs of a merchant cash advance can include a factor rate and additional fees that would typically translate to a high annual percentage rate (APR) if it were a traditional bank loan.

With a merchant cash advance, reports indicate that you can wind up with an APR of close to or even more than 100%.

The APR on a small business microloan, meanwhile, might have APRs between 8.00% and 13.00%. SBA microlenders (partnering with the U.S. Small Business Administration) may offer microloans of up to $50,000.

How Do You Calculate a Factor Rate?

To calculate the total cost of the loan with a factor rate, simply multiply the loan amount by the factor rate.

Here’s an example of a factor rate in action: Say a business owner takes out a merchant cash advance (MCA) for $10,000 and the factor rate is 1.2.

$10,000 x 1.2 = $12,000

So $12,000 is the total amount of money owed on the merchant cash advance if the provider doesn’t charge additional fees. (Some MCA providers may charge additional fees on top of the factor rate.)

An MCA is a common type of sales-based financing that charges a factor rate – in contrast with, say, a short-term business loan that charges interest.

What Lenders Look at to Determine a Factor Rate

As with a lender that issues interest rate loans, a lender that offers sales-based financing with a factor rate generally also wants to know that borrowers will be able to pay the financing back. Even though taking payments directly from a merchant’s sales provides some security to the lender, if a borrower is perceived as riskier, it might be offered a higher factor rate.

Every lender has its own requirements, of course. But across the board, in order to determine your factor rate, a lender may ask to see:

•   Credit card processing statements. The lender will want to see proof that you have credit card sales high enough for it to deduct payments from them.

•   Bank statements. A lender may want a sense of your business’s cash flow and general financial situation, so it may request some of your recent bank statements.

•   Time in business. Typically, lenders prefer to lend to businesses that have been operating for at least a year.

•   Business tax return. This will help the lender assess the financial health of your business.

Lenders may consider other factors when determining your factor rate, but these are among the most likely components.

Factor Rate vs Interest Rates

Although it’s similar in some ways, a factor rate is not the same thing as an interest rate. As mentioned earlier, a factor rate is a percentage of a commercial financing offer, and the rate is typically expressed as a decimal figure between 1.1 and 1.5. Sales-based financers, including merchant cash advance providers, can make money by charging this factor rate.

Factor rate example: A $10,000 MCA with a 1.2 factor rate would cost at least $12,000. The factor rate doesn’t necessarily tell you the total cost of the MCA, because MCA providers can charge additional fees on top of the factor rate.

An interest rate is a finance charge typically expressed as an annual percentage of a borrower’s outstanding principal. State usury laws can limit the maximum interest rate that lenders charge on traditional loan products. You can typically minimize your total interest charges by paying a loan off early.

Interest rate example: A $10,000 microloan with a 7.00% interest rate, five-year repayment plan, and no additional fees would cost about $11,880 after 60 months. The total borrowing costs would be lower if there’s no prepayment penalty and you pay the loan off early.

Here are some points to keep in mind:

•   The interest rate doesn’t necessarily tell you the total cost of a loan, because lenders can charge additional fees on top of the interest rate charges.

•   A merchant cash advance is a sales-based financing solution that typically charges a factor rate, whereas traditional loans typically charge interest.

•   APR takes the interest rate and upfront fees into account, so it can give you a better idea of a loan’s total cost than the interest rate alone.

Pros and Cons of Factor Rates

Here are some pros and cons of factor rates.

Pros of Factor Rates

•   It’s relatively easy to calculate costs upfront.

•   Funding times are typically faster for factor rate products, such as merchant cash advances.

•   Factor rate products may have less rigorous credit score requirements than other forms of financing.

Cons of Factor Rates

•   The charges cannot be minimized via prepayment.

•   They’re a nontraditional commercial financing term.

•   Factor rates can translate into APRs of 70% or higher.

MCA Factor Rates: What to Expect

Generally, MCA factor rates range between 1.1 and 1.5, though in some cases it’s possible for them to go higher. If you decide to get an MCA, you might be paying your lender a percentage (that you’d agree upon in advance) of your credit and debit card sales each day. Or you might allow the lender to withdraw an agreed-upon percentage of funds from your bank account, according to the schedule you establish. When the full amount you owe (including any fees) is paid off, the transaction is complete.

The Takeaway

A factor rate is the percentage of the loan amount that a borrower must pay to pay back a loan, expressed as a decimal. It’s a nontraditional financing term typically used by merchant cash advance providers. Nonbank finance companies may charge a factor rate along with additional fees.

Typically, loans that come with factor rates end up being more expensive than traditional small business loans.

FAQ

What is a factor rate?

Also known as a loan factor, a factor rate is a fee structure used in merchant cash advances and some short-term business loans. It’s expressed as a decimal, such as 1.2 or 1.4, rather than a percentage and determines the total repayment amount (plus any fees).

How is a factor rate calculated?

To calculate the total repayment, multiply the loan amount by the factor rate. For instance, a $10,000 loan with a factor rate of 1.2 would require repayment of $12,000 (plus any fees). Factor rates do not accrue over time, and the total repayment amount is fixed from the start, making it easier to understand the full cost of borrowing.

How do factor rates work?

Factor rates are fees that lenders charge for certain types of business loans, mainly merchant cash advances. They are expressed as a decimal rather than a percentage, and they’re multiplied by the total loan amount. If you took out a loan for $10,000, for example, and a factor rate of 1.3, you would multiply those two numbers together for a total of $13,000. The factor rate calculates a flat fee, and it does not grow over time.

How does a factor rate differ from an interest rate?

A factor rate is a percentage of a commercial financing offer, and the rate is typically expressed as a decimal figure between 1.1 and 1.5. By contrast, an interest rate is a finance charge typically expressed as an annual percentage of a borrower’s outstanding principal, such as 8.00%.

How do I convert a factor rate to an APR?

First, multiply your advance by your factor rate minus one to get the full cost of the loan interest. Next, divide that figure by the number of days you have to pay off the loan to get the daily cost. Divide this by the amount you borrowed and then multiply by 365 to arrive at the APR.
