Factor rate vs APR, worked through on one $50,000 advance
Who this page is for: owners comparing an advance with other funding, and anyone who needs the math shown step by step.

How is a factor rate different from an interest rate?
A factor rate is a one-time multiplier on the purchase price, while an interest rate accrues over time on a declining balance.
With a factor rate, the cost is set on day one and does not shrink if the advance is collected early. With interest, paying sooner usually means paying less.
How does the same factor rate produce different APRs?
The same factor rate gives different APRs. APR measures cost per year, and a shorter payback packs the cost into less time.
Here is an illustrative $50,000 advance at a 1.35 factor, so a purchased amount of $67,500, collected by equal debits every business day:
Put two real offers through the same math on the comparison sheet before you choose. See how a merchant cash advance works for where the factor rate sits in the contract.
| Estimated term | Business-day debit | Approximate APR |
|---|---|---|
| 6 months (126 business days) | $535.71 | about 126% |
| 9 months (189 business days) | $357.14 | about 84% |
| 12 months (252 business days) | $267.86 | about 63% |
Method: internal rate of return on the daily cash flows, multiplied by 252 business days per year, with no fees. Fees taken at funding raise the APR further; on the six-month example, $1,500 in fees lifts it to about 140%. These are illustrations of the math, not typical offers.
Why disclosure laws ask for an estimated APR
Disclosure laws require an estimated APR. That lets a business compare an advance with loans and credit lines on one yardstick. California's DFPI rules require an APR or estimated APR on covered offers. The term of an advance is a guess, so the APR is a guess too. It rests on how soon the funder expects sales to come in.
Why does an estimated APR change after funding?
An estimated APR changes after funding because the actual collection period differs from the funder's estimate.
Receivables that arrive sooner than expected shorten the term and raise the effective annual cost; slower ones lower it.
How the funder projects collection time
The funder projects how long collection will take from past receivables. The APR on a disclosure rests on that projection.
A busy season on a split holdback
If sales rise and the advance is collected through a split holdback, collection speeds up. The same dollar cost is paid in less time.
Nine months shrinking to six
On a split, a busy season that shortens collection from nine months to six moves the illustrative APR from about 84% toward about 126%. The dollar cost stays the same.
Why a fixed debit ignores the busy season
With a fixed daily debit, a sales rise does not change the schedule. The estimated term and APR hold unless the contract reconciles upward.
Fixed debits that reconcile on request
Where a fixed-debit contract reconciles, a slow season can lower the debit on request. A busy season rarely raises it unless the contract says so.
When the factor rate tells you more
Factor rate is more useful when comparing total dollars paid back between two advances of similar length. APR is more useful when comparing across products or across different terms.
Use both, together with net cash after fees. If you send us an offer, we will run this conversion on its numbers.
A renewal is where the two numbers most often disagree.
Rate questions
Owners converting a factor rate usually ask these.
How do I turn a factor rate into an APR?
Multiply the purchase price by the factor rate to get the total payback. Spread that total over the expected payment schedule. Then solve for the yearly rate that matches those payments to the cash received. Without the term and payment frequency, a factor rate cannot be turned into an APR.
Is a 1.2 factor rate the same as 20 percent interest?
No, a 1.2 factor means the business pays back 20 percent more than the purchase price in total, regardless of time. Collected over a few months, that works out to a much higher annual rate than 20 percent. The shorter the term, the higher the APR.
Why does paying an advance off early not lower the cost?
The factor rate fixes the total dollars owed at the start. Paying early only shortens the time, which raises the effective annual cost unless the contract offers an early payoff discount. Check the prepayment terms.
Sources
- New York Financial Services Law section 803 requires a sales-based financing offer to show an estimated APR. It is worked out under Regulation Z from the expected term and payments (NYSenate.gov, fetched 2026-09-24). That is why a factor rate vs APR comparison shifts when the term does.

Cost, credit, speed and stacking
- Cost
- The factor sets the dollars you repay, and the APR spreads them over time. Look at both, then compare net cash after fees.
- Credit
- Neither number answers the credit question, so ask the funder about that before you sign.
- Speed
- A shorter payback raises the APR on the same dollars. We make no promise on how soon an offer arrives.
- Stacking
- Two advances at once mean two factors and two schedules. Add the debits together before you judge either APR.
