Calculator

Factor rate to APR calculator

A factor rate is not an interest rate, and treating it like one is the most expensive arithmetic error a small business can make. This converts a factor rate, a repayment frequency, and a term into a true APR on the money you actually receive.

Your numbers

The figure on the offer, before any fees are deducted.

Usually between 1.15 and 1.50. Multiply by the advance to get the total you must repay.

Origination, underwriting, or ACH set-up fees taken out of the wire. You repay against these but never have use of them.

Repayment frequency

With a revenue-share advance this is an estimate - repaying faster raises the true APR, not lowers it.

For comparison

An amortising term loan of $48,500 at 11% over the same 9 months would cost about $2,250 in interest - against $19,000 here. That is 8.4× the cost for the same money over the same period.

At this cost, the money needs to generate a return above 93% annualised to leave you better off. Before signing, it is worth checking whether an SBA Express line, factoring, or a CDFI loan could arrive in time instead.

This calculator runs entirely in your browser. Nothing you type is sent to us, stored, or shared. APR is computed by solving for the rate that equates the payment stream to the cash actually received, using 252 periods a year (business days, the standard for daily-debit advances). Because most advances fix the total repayable regardless of timing, repaying faster than expected raises the effective APR. Results are estimates for comparison only - they are not an offer, a quote, or advice, and your actual terms will be set by a lender.

Why a factor rate understates the cost so badly

An interest rate accrues on a declining balance: as you repay, you owe interest on less. A factor rate does not. The total repayable is fixed the moment you sign - advance multiplied by factor - and you pay it down continuously while having use of steadily less of the money.

That is why a 1.3 factor over six months is roughly twice as expensive, in APR terms, as the same 1.3 factor over twelve. The shorter the term, the higher the true cost of an identical-looking headline number.

Fees deducted from the wire

Origination, underwriting, and ACH set-up fees are commonly deducted before funding. You never have use of that money but you repay against it, so it belongs in the APR calculation. This calculator subtracts it from the amount received, which is the correct treatment and the one most funders' own illustrations omit.

What the disclosure laws now require

Several states - New York, California, Utah, Virginia, and others - now require providers of commercial financing under a threshold amount to give standardised disclosures including an estimated APR and total cost before you sign. Where you are entitled to one, read it and compare it against what you were told verbally.

Questions

What APR is a 1.4 factor rate?
It depends entirely on how long repayment takes. Over 12 months a 1.4 factor is roughly an 80% APR equivalent; over 6 months the same factor is roughly 170%. The factor rate alone tells you nothing about the cost of the money.
Why does repaying early not save me money?
Most advance agreements fix the total purchased amount regardless of how fast you deliver it. Unlike a loan, there is no unaccrued interest to save. Some funders offer an early-delivery discount, but it is a contractual concession that has to be written in.
Is a merchant cash advance ever the right choice?
When the money funds something that returns more than the true APR, faster than the repayment term, and no cheaper capital can arrive in time. That is a narrow window, and it is worth checking an SBA Express line, factoring, or a CDFI first.
