The difference between a factor rate and an interest rate is not just a technical distinction — it is the difference between understanding what you are actually paying for business financing and being misled by numbers that make expensive products appear affordable. Factor rates are used primarily by merchant cash advance (MCA) providers and some short-term online lenders. Interest rates are used by traditional lenders. When you are comparing financing options, using both without converting to a common basis (APR) makes informed comparison impossible. This guide explains exactly how each pricing method works, how to convert between them, and why factor rate products almost always cost more than they initially appear.

A factor rate is a pricing mechanism used primarily for merchant cash advances and some short-term business loans. It is expressed as a decimal multiplier (typically 1.1 to 1.5+) that is applied to the advance or loan amount to calculate the total repayment.
Why Factor Rates Are Confusing: A 1.35 factor rate sounds like 35% — which, for a conventional loan, would be considered high but not extreme. But factor rates are not annual rates. A 1.35 factor on a 6-month advance translates to approximately 70% APR. A 1.35 factor on a 3-month advance translates to approximately 140% APR. The same factor rate produces very different effective costs depending on repayment speed.
An interest rate is charged as a percentage of the outstanding principal balance over time. As you repay principal, the interest charged on future periods decreases proportionally — meaning early payoff genuinely saves money.
| Feature | Factor Rate | Interest Rate |
|---|---|---|
| Expressed as | Decimal multiplier (1.2, 1.35) | Percentage per year (12%, 25%) |
| Applied to | Original advance amount (flat) | Outstanding balance (declining) |
| Early payoff benefit | None (total fixed at signing) | Yes — eliminates future interest |
| Total cost certainty | Known at origination | Depends on repayment speed and rate type |
| Comparable to other products | Must convert to APR first | APR is already standardized |
| Typical products | MCAs, some short-term loans | Term loans, lines of credit, SBA loans |
| Regulatory protection | Often exempt from usury laws | Subject to interest rate regulations |
Converting a factor rate to approximate APR enables direct comparison with interest-bearing products:
| Factor Rate | Repayment Term | Approx. APR | Cost on $100K |
|---|---|---|---|
| 1.20 | 6 months (180 days) | ~41% | $20,000 |
| 1.30 | 6 months (180 days) | ~61% | $30,000 |
| 1.35 | 6 months (180 days) | ~71% | $35,000 |
| 1.40 | 4 months (120 days) | ~122% | $40,000 |
| 1.49 | 3 months (90 days) | ~199% | $49,000 |
Notice that the same 1.40 factor rate produces very different APRs depending on term — 80% at 6 months versus 122% at 4 months. This is why the term (expected repayment period) is essential context for any factor rate disclosure.
Comparing the same $75,000 in financing under different pricing structures over 6 months:
| Product | Rate/Factor | Total Cost (6 months) | Monthly Payment |
|---|---|---|---|
| MCA (factor 1.35) | Factor 1.35 (~71% APR) | $26,250 | ~$1,780/day ACH |
| Online Term Loan | 30% APR | $11,440 | $14,240/month |
| Business Line of Credit | 18% APR | $6,375 | Interest only on balance |
| SBA Express Loan | 12% APR | $2,720 | $12,980/month |
The MCA costs $26,250 for the same $75,000 over 6 months. The SBA loan costs $2,720 — a $23,530 difference in financing cost for the same principal over the same period.

Factor rates serve several purposes for lenders:
It is important to note: using a factor rate is not inherently dishonest. The problem is not the pricing mechanism — it is when the factor rate is presented without APR conversion, making comparison to alternatives impossible. For more on how interest is calculated across different loan types, see our How Business Loan Interest Is Calculated: A Step-by-Step Guide.
Despite their high cost when properly converted to APR, factor rate products (MCAs) have legitimate use cases:
The key: always convert to APR, always compare to alternatives, always quantify the ROI of the specific use case, and always have an exit plan toward lower-cost financing.
