A merchant cash advance is priced with a factor rate rather than an interest rate, so the true annual cost is hidden until you convert it. Multiply the advance by the factor rate to get the payback amount, then work out the annualized rate from how fast you repay. A $50,000 advance at a 1.30 factor rate costs $15,000; repaid at $500 per business day over 130 business days, that is an APR of roughly 106%.
Here is how the product works, how to estimate the APR yourself, and what disclosures you may be entitled to.
How does a merchant cash advance work?
A provider pays you a lump sum in exchange for a share of your future sales or receivables. You repay through a fixed daily or weekly debit from your bank account, or through a percentage of card sales. Because it is structured as a purchase of future receivables rather than a loan, it is often outside federal lending disclosure rules such as Truth in Lending, which applies to consumer credit. That is why you usually see a factor rate instead of an APR.
The Federal Reserve Banks’ Small Business Credit Survey tracks how often firms use a merchant cash advance. Its 2026 report on employer firms counts merchant cash advances alongside loans and lines of credit when measuring financing applications.
How do I convert a factor rate into an APR?
Use three numbers: the advance, the total payback and the repayment period.
Worked example:
- Advance: $50,000
- Factor rate: 1.30
- Payback: $50,000 × 1.30 = $65,000
- Cost: $15,000
- Daily debit: $500 per business day
- Days to repay: $65,000 ÷ $500 = 130 business days, about six months
Treating each daily payment as a cash flow and assuming 252 business days a year, the annualized rate that equates $50,000 today with 130 payments of $500 is about 106%. If the same $65,000 were spread over 260 business days, the rate would drop to about 53%. The faster the repayment, the higher the APR for the same dollar cost. Run your own figures in the merchant cash advance APR calculator.
Why does the factor rate look cheaper than it is?
A 1.30 factor rate sounds like 30%, but that 30% is charged on the full advance even though you repay part of it every day. Your average outstanding balance is roughly half the advance, so the effective rate is far higher than the headline figure. A term loan with the same total cost over the same period would show a much higher APR than 30% too, for the same reason. Compare the real cost with the APR calculator and the business loan calculator.
What should I ask the provider before signing?
Ask for the exact amount you will receive after fees, the total payback, the daily or weekly debit, and what happens if sales fall. Ask whether the remittance can be adjusted to match actual revenue and how to request it. Get every answer in writing so you can calculate the APR yourself.
What disclosures are required?
Rules vary by state. California’s commercial financing disclosure law, SB 1235, requires a provider that extends a specific offer of commercial financing to give the recipient disclosures before the deal is finalized, and the recipient must sign them. According to the California Department of Financial Protection and Innovation, the disclosures include:
- The total amount of funds provided
- The total dollar cost of financing
- The term or estimated term
- The method, frequency and amount of payments
- A description of prepayment policies
The DFPI’s regulations set how an annualized rate is calculated and shown. Outside California, ask the provider in writing for the total payback, the expected term and any fees before you sign a merchant cash advance.
Does repaying a merchant cash advance early save money?
Often not. Many agreements fix the total payback at the start, so paying early does not reduce the $15,000 cost unless the contract offers a discount for early payoff. Read the prepayment section carefully and get any discount in writing. With a loan, interest usually stops accruing when you repay, which is a key difference.
What other risks come with a merchant cash advance?
- Stacking: taking a second advance while the first is outstanding, which multiplies daily debits
- Cash flow strain from fixed daily payments during a slow month
- Fees deducted from the advance, which reduce the cash you actually receive and raise the true rate
- Confessions of judgment or personal guarantees in the contract
For example, if a $1,500 origination fee is deducted from a $50,000 merchant cash advance, you receive $48,500 but still repay $65,000, so the true rate rises above the 106% calculated earlier. If fees are taken out up front, use the net amount received as the advance in the APR calculation.
When does a merchant cash advance make sense?
It can fit a business with strong card sales, a short-term need and no access to cheaper credit. It works best when the money produces a quick, measurable return that exceeds the cost. Compare at least two written offers side by side, using the same net amount received and the same repayment speed. Before signing, check whether a bank line of credit, an SBA-backed loan or invoice factoring could cover the same need for less, and confirm your margins with the profit margin calculator. Treat any merchant cash advance as an expensive bridge rather than ongoing working capital.
