Factor Rate vs. Interest Rate and APR: An Honest Comparison

Factor rate vs. interest rate and APR: why a 1.25 factor rate is not 25% interest, why APR math is tricky for an MCA, and how to estimate an equivalent cost.

Updated October 1, 2026 · 6 min read

A factor rate and an interest rate (or APR) measure cost in different ways, so you cannot compare them directly. A factor rate is a one-time multiplier: $10,000 at a 1.25 factor rate means you remit $12,500, no matter how long it takes. An interest rate or APR expresses cost per year on the balance you still owe, so a 1.25 factor rate remitted over six months works out to an equivalent annualized cost far above 25%.

Below, we explain why the comparison is tricky, show how to estimate an honest equivalent cost, and cover what that number can and cannot tell you.

Factor rate vs. interest rate: the core difference

Factor rate (MCA) Interest rate / APR (loan)
What it is A fixed multiplier on the advance A yearly percentage charged on the balance
When cost is set At signing, in dollars Over time, as the balance is paid down
Effect of paying faster Same dollar cost (unless an early payoff discount applies) Less interest paid
Effect of a longer term Same dollar cost More interest paid
Legal nature Purchase of future receivables Debt
Typical expression 1.10 to 1.50 Percent per year

The biggest difference is how time works. With a loan, interest accrues on the remaining balance, so paying early saves money. With most MCAs, the purchased amount is fixed on day one. You remit the same total whether it takes four months or ten. If you want the full background on factor rates, start with factor rate explained.

Why the “just subtract 1” shortcut is wrong

It is tempting to look at a 1.25 factor rate and think “25%.” That is misleading for two reasons.

First, the term is usually short. A loan’s 25% APR is a cost per year. If an MCA’s $2,500 cost on a $10,000 advance is remitted over six months, that is 25% for half a year, which is already about 50% on a simple yearly basis.

Second, you pay down the balance as you go. With daily or weekly remittances, you do not hold the full $10,000 for the whole term. On average, you hold about half of it. Paying a fixed cost on a balance that shrinks every day pushes the equivalent rate even higher, roughly doubling it again.

Put those together and a 1.25 factor rate over six months lands somewhere around 90% on an annualized basis. That number surprises a lot of business owners, but it is the honest way to compare it with a loan.

How to estimate an equivalent APR honestly

The fair method treats the MCA like any other set of cash flows: money in today, a series of remittances out. You solve for the rate that makes them balance. This is the same idea behind the APR on a car loan or mortgage.

What you need

  1. Net funding: the cash that actually lands in your account after fees.
  2. Remittance amount: the daily or weekly amount.
  3. Number of remittances: how many daily or weekly payments the purchased amount should take, based on your expected sales.
  4. Payment frequency: roughly 252 business days a year for daily, 52 for weekly.

How to run it

In a spreadsheet, use the RATE function: =RATE(number_of_payments, -payment, net_funding). That gives a rate per period. Multiply by the number of periods per year (252 for daily business-day remittances, 52 for weekly) to get an estimated APR.

Worked example

Take an illustrative $30,000 advance at a 1.25 factor rate, so the purchased amount is $37,500.

Scenario Expected term Remittances Daily remittance Estimated APR
A About 4 months 84 business days $446.43 about 138%
B About 6 months 126 business days $297.62 about 92%
C About 12 months 252 business days $148.81 about 46%

The factor rate and dollar cost ($7,500) are identical in all three rows. Only the term changes, yet the estimated APR ranges from about 46% to about 138%. That is the single most important thing to understand about converting factor rates.

Fees push the number higher. In scenario B, if a 3% origination fee ($900) is taken from the funding, you receive $29,100 but still remit $37,500. The estimated APR rises from about 92% to about 105%.

And a lower factor rate helps, but less than people expect. The same $30,000 at a 1.18 factor rate over 126 business days ($280.95 per day) still works out to about 68%.

Why any MCA “APR” is an estimate

Be cautious with any single APR figure for an MCA, including your own calculation. Here is why:

  • The term is not fixed. With a true sales-based advance, the term depends on your actual receivables. If sales slow and remittances are reconciled down, the term stretches and the annualized cost falls. If sales surge under a split-funding setup, the term shortens and the annualized cost rises.
  • Fixed-remittance advances are based on an estimate. Many MCAs use a set daily or weekly ACH amount derived from your average revenue. The “expected term” assumes that amount continues as scheduled.
  • Early payoff terms vary. If your agreement has an early payoff discount, the effective cost changes depending on when you pay.

So treat an estimated APR as a comparison tool, not a promise. Several states, including California and New York, require certain commercial financing providers to disclose an estimated APR or similar metrics. Other states such as Utah, Virginia, Georgia, and Florida have their own disclosure rules, and Texas added registration rules in 2025 for some commercial sales-based financing providers and brokers. Rules differ and change, so check your state’s current requirements. Our overview of merchant cash advance regulation by state is a good starting point.

Is a high APR always a bad deal?

Not necessarily. APR measures cost per year, but many business decisions are about cost per opportunity. A few examples of when a higher annualized cost may still make sense:

  • You need funds in days, not weeks, to take a time-sensitive opportunity.
  • The money funds something with a short, clear payback, such as a bulk inventory discount you can sell through quickly.
  • You do not qualify for lower-cost options right now.

And some cases where it usually does not make sense:

  • Covering ongoing losses with no plan to fix them.
  • Paying off another advance just to buy time.
  • Funding a project with a slow or uncertain return.

The right question is often: “Will this money earn or save more than its total dollar cost, within the time I am remitting it?” Our guide on when a merchant cash advance makes sense walks through that thinking.

Comparing an MCA with a loan offer: a checklist

When you have an MCA offer and a loan or line of credit offer side by side, compare them on more than one number:

  • Net cash received after all fees
  • Total dollars remitted or repaid over the life of the deal
  • Total cost in dollars (total remitted minus net cash)
  • Estimated APR, calculated the same way for both
  • Remittance or payment size, and whether it is daily, weekly, or monthly
  • Speed of funding: MCAs are often funded within 24 to 72 hours of approval; bank and SBA loans usually take longer
  • Flexibility if sales drop: is there a reconciliation process?
  • Collateral and personal guarantee requirements
  • Early payoff terms

The bottom line

A factor rate and an interest rate are built differently, so the factor rate vs. interest rate comparison only works once you convert both into the same terms. Estimate an equivalent APR using your net funding, remittance amount, and expected term, and remember that it is an estimate that shifts with your sales. Then weigh it alongside total dollar cost, speed, and flexibility before deciding.

Quick answers

Is a 1.25 factor rate the same as 25% interest?

No. A 1.25 factor rate means you remit $1.25 for every $1 received, but that cost is fixed and is usually remitted over a few months. On an annualized basis, the equivalent cost is typically much higher than 25%.

Why don't merchant cash advances quote an APR?

An MCA is a purchase of future receivables, not a loan, and the term depends on how fast your sales come in. Without a fixed term, a single APR is hard to calculate. Some states now require an estimated APR or similar disclosure for certain commercial financing.

How do I estimate the APR of a merchant cash advance?

Use the net cash you receive, the remittance amount, and the expected number of remittances, then solve for the rate that makes them equal, the same way a loan APR is calculated. A spreadsheet RATE function can do this.

Does a shorter term make an MCA more expensive?

The dollar cost stays the same, but the annualized cost rises. Paying the same fixed cost over a shorter period means a higher equivalent rate.

Should I choose financing based only on APR?

Not only. APR is useful for comparison, but total dollar cost, remittance size, speed, and flexibility also matter. Look at all of them together.
