A factor rate is a fixed multiplier applied once to the amount you borrow. An interest rate is a yearly percentage charged on a balance that shrinks as you repay. The two are not the same unit, which is why a 1.3 factor rate cannot be read as "30% interest" and why a short repayment term can make it far more expensive than it looks.
This guide shows how each one works, how to calculate your total cost from a factor rate, how to estimate an APR so you can compare offers fairly, and what to check before you sign.
TL;DR
- A factor rate (for example 1.3) multiplies your advance to give the total you repay. A $50,000 advance at 1.3 means $65,000 back, a $15,000 fee.
- An interest rate is annual and charged on a declining balance. APR adds certain fees on top, so it is the better yardstick for comparing loans.
- With a factor rate, the cost is generally fixed no matter how fast you repay, so a shorter term means a much higher effective annual cost.
- To compare, estimate an APR from the factor rate, the repayment days and every fee, then put the offers side by side in dollars as well as percentages.
- Ask for the total repayment, the payment schedule and any prepayment terms in writing before you accept.

What a factor rate is
A factor rate is written as a decimal, usually between 1.1 and 1.5. You multiply the amount you receive by the factor rate to get the total you owe. Bankrate explains that total repayment is the amount borrowed times the factor rate, and the fee is the difference. Its example: $100,000 × 1.5 = $150,000 repaid.
Three things follow from that design:
- The cost is set on day one. There is no balance to compound on and no rate that moves.
- Term does not change the fee. The Wall Street Journal's guide notes that a factor rate gives the same borrowing cost regardless of loan term, while a loan with an APR costs more in interest the longer you take to repay.
- The number says nothing about time. A 1.2 factor rate repaid in four months and a 1.2 factor rate repaid in fourteen months cost the same dollars, but they are very different deals per year of borrowing.
Factor rates are most associated with short-term, non-bank products such as merchant cash advances and some short-term working capital advances. Longer bank and SBA-style term loans are generally quoted with an interest rate or APR instead. Always read the contract to see which method the offer uses.
What an interest rate and APR are
An interest rate is the yearly price of borrowing, expressed as a percentage of the outstanding balance. On an amortizing loan, each payment covers some interest and some principal, so the interest portion falls over time.
APR is a broader figure. The Consumer Financial Protection Bureau says that APR is the interest rate plus additional fees the lender charges, such as origination charges. That is why two loans with the same interest rate can have different APRs, and why APR is the number to compare when you can get one. If you want to see typical ranges, our guide to what U.S. small businesses pay for bank term loans lays out the interest-rate side.
Factor rate vs interest rate side by side
| Factor rate | Interest rate / APR | |
|---|---|---|
| Format | Decimal multiplier (1.3) | Annual percentage (12%) |
| Applied to | Original amount, once | Remaining balance, over time |
| Total cost known upfront | Yes, simple multiplication | Depends on term and schedule |
| Effect of a longer term | Fee generally unchanged | More total interest |
| Effect of paying early | Often little or no savings, depending on contract | Interest stops accruing on the paid balance |
| Includes fees | Not by itself | APR includes certain fees |
| Easy to compare across offers | No, it hides time | Yes, if APR is disclosed |
The last row matters most. A factor rate is simple to understand and hard to compare, because it leaves out how long you hold the money.
How to calculate your cost from a factor rate
Start with dollars, since that is the part the factor rate states clearly.
- Multiply the advance by the factor rate. $50,000 × 1.3 = $65,000.
- Subtract the advance. $65,000 − $50,000 = $15,000 in cost.
- Add any fees the lender deducts or charges separately, such as origination or administrative fees. Also check whether they are taken out of the funds you receive. If $1,000 is deducted upfront, you receive $49,000 but still repay $65,000.
- Divide total repayment by the number of payments to see the daily, weekly or monthly amount, and compare that with your actual cash flow.
The WSJ's view is that total borrowing cost is the clearest first comparison, because a factor rate does not annualize cost or capture every fee. We agree. Total dollars repaid, and what share of your revenue goes out each day or week, are the numbers that show whether an offer is manageable.
How to convert a factor rate to an estimated APR
To compare a factor-rate offer with a loan, turn it into an annualized figure. The most common back-of-the-envelope method is:
APR ≈ ((factor rate − 1) × 365 ÷ repayment days) × 100
If fees apply, add them to the cost before dividing: ((total repayment + fees − amount received) ÷ amount received × 365 ÷ repayment days) × 100.
Here is the same $50,000 advance at a 1.3 factor rate, with the only change being how quickly you repay:
| Repayment period | Days | Cost | Estimated APR |
|---|---|---|---|
| 3 months | 91 | $15,000 | about 120% |
| 6 months | 182 | $15,000 | about 60% |
| 12 months | 365 | $15,000 | 30% |
The cost never moves. The estimated APR changes fourfold. This is the effect the research above describes: with a factor rate, speed of repayment does not reduce the fee, so the annualized cost climbs as the term shrinks.
What changes the result
- Repayment days. Use the realistic number. If payments are tied to a percentage of daily sales, the term can stretch or shrink with your revenue, so your estimate is a range.
- Fees. Origination, underwriting, broker and processing fees all push the effective cost up. Include every one.
- Payment frequency. The simple formula treats the whole advance as outstanding until the last day. With daily or weekly payments, you hold less than the full amount for most of the term, so the true annualized cost on the average balance is higher than the simple estimate. Treat the formula as a floor, not a ceiling.
- Funds actually received. If fees are withheld from the advance, divide by what landed in your account, not the headline amount.
For an exact figure, ask the provider for an APR or an effective-cost disclosure, or run the payment schedule through a spreadsheet's rate function. Disclosure rules for these products vary by state and product type, so do not assume an APR will appear on the paperwork.
A worked comparison: 1.3 factor rate vs a 12% loan
Suppose you need $50,000 for one year.
- Term loan at 12% APR, 12 monthly payments. The payment is about $4,442. You repay about $53,309, so the cost is about $3,309.
- Advance at a 1.3 factor rate, repaid over 12 months. You repay $65,000, so the cost is $15,000.
The factor-rate offer costs roughly $11,700 more. Expressed as an equivalent factor rate, the 12% loan works out to roughly 1.07. That gap is the price of speed, looser underwriting or less documentation, and for some businesses it is worth paying. The point is to know you are paying it.
Now flip the question. If the advance is repaid in three months, you pay $15,000 for a quarter of borrowing. Put next to a one-year loan, that is a different product, and the estimated APR near 120% is the honest way to express it.
Which financing uses which pricing
| Product | Typical pricing language |
|---|---|
| Merchant cash advance | Factor rate |
| Short-term working capital advance | Factor rate or fixed fee |
| Invoice factoring | Discount or fee percentage per period, see our invoice financing vs factoring breakdown |
| Business line of credit | Interest rate or APR plus fees, see line of credit rates |
| Bank and SBA term loans | Interest rate, APR |
| Equipment and commercial real estate loans | Interest rate, APR |
Names vary between lenders, so check the contract language rather than the label on the product.
What affects the factor rate you are offered
Lenders set a factor rate from their view of risk and speed. The usual drivers are your monthly revenue and its consistency, time in business, existing debt or other advances, your industry, the size and length of the advance, and your credit profile. Lower risk and a longer term generally mean a lower multiplier, but there is no standard scale, so two lenders can quote different factor rates for the same business on the same day. That is the practical reason to collect more than one offer.
What to compare before you sign
- Total repayment in dollars. The single most useful number.
- Estimated APR. Use the formula above, with fees included.
- Payment schedule. Daily, weekly or a share of sales. Divide by your typical revenue to see the strain.
- Fees and what is deducted upfront. Origination, underwriting, administrative. Our piece on business loan origination fees shows how they stack up.
- Early payoff. Ask whether paying early reduces the cost. With a fixed factor rate it often does not. See what to look for in prepayment penalties.
- Recourse and security. Personal guarantees, liens, and for receivables products, whether you carry the risk if a customer does not pay. Our guide to recourse vs nonrecourse factoring covers that.
- Stacking restrictions. Some agreements limit taking on other financing.
If an offer cannot be explained clearly in dollars, days and fees, treat that as information.
Our perspective
We see the same mistake often: an owner compares a 1.25 factor rate to a 14% interest rate and concludes the factor rate is cheaper because 1.25 looks small. The two numbers are in different units, and the only fair test is total dollars over a stated period, converted to an APR.
Our approach is to put several real offers in front of a business at once, so that comparison is on the table instead of in your head. Factor-rate products have a place when speed matters and the cash will earn back more than it costs, for example inventory that turns quickly. They are a poor fit when the money will sit idle or the repayment will squeeze payroll. When the timeline allows, lower-cost options such as a line of credit or an SBA loan deserve a look first, and our online lenders vs banks guide explains the speed-versus-cost trade-off.

FAQ
Is a factor rate the same as an interest rate?
No. A factor rate is a multiplier applied once to the original amount, so the total cost is fixed from the start. An interest rate is an annual percentage applied to a declining balance, so cost depends on how long you borrow.
How do I calculate a factor rate payment?
Multiply the amount you receive by the factor rate to get total repayment, then divide by the number of payments. For $50,000 at 1.3, the total is $65,000. Over 180 daily-business-day payments, that is about $361 per payment, before any fees.
How do I convert a factor rate to APR?
Subtract 1 from the factor rate, multiply by 365, divide by the number of repayment days, then multiply by 100. Add any fees to the cost first. The result is an estimate, and it tends to understate the true cost when you repay in frequent small installments.
Is a lower factor rate always cheaper?
Not necessarily. A 1.2 factor rate repaid in three months can carry a higher annualized cost than a 1.4 factor rate repaid over a year. Compare total dollars, repayment days and fees together.
Can I save money by paying a factor-rate advance off early?
Often not, since the fee is calculated upfront on the full amount. Some agreements offer a discount for early payoff and others do not, so ask for the terms in writing before you sign.
