Factor Rate vs. Interest Rate: Understanding the True Cost of Your Loan
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.

What Is a Factor Rate?
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.
Cost of Capital = Total Repayment − Advance Amount
Example: $50,000 × 1.35 = $67,500 total repayment | Cost = $17,500
Key Characteristics of Factor Rate Pricing
- Fixed total cost: The cost is determined at origination and does not change regardless of how quickly or slowly you repay
- No benefit to early repayment: Unlike interest-bearing loans where early payoff saves interest, factor rate products cost the same whether repaid in 90 days or 270 days
- Not subject to usury laws: Because MCAs are technically a purchase of future receivables (not a loan), they are often exempt from state interest rate caps that protect borrowers from excessive interest rates
- Cannot be directly compared to interest rates: A 1.35 factor rate does not equal 35% interest — it must be converted to APR for legitimate comparison
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.
What Is an Interest Rate?
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.
Monthly Rate = Annual Interest Rate ÷ 12
Example: $50,000 at 18% APR → Monthly rate = 1.5% → First month interest = $750
As balance decreases, monthly interest decreases proportionally.
Key Characteristics of Interest Rate Pricing
- Based on declining balance: Interest only accrues on what is still owed — reducing with each principal payment
- Early payoff saves money: Every dollar of principal you pay early eliminates future interest on that amount
- Standardized disclosure: APR (Annual Percentage Rate) is the standardized expression for comparing across lenders
- Regulated: Subject to usury laws, Truth in Lending Act disclosures (for consumer loans), and commercial lending regulations
Key Differences: Factor Rate vs. Interest Rate
| 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 |
How to Convert Factor Rate to APR
Converting a factor rate to approximate APR enables direct comparison with interest-bearing products:
Step 2: Divide by term in days: (Factor Rate − 1) ÷ Days in term
Step 3: Annualize: × 365
APR ≈ (Factor Rate − 1) ÷ Days in Term × 365
Conversion Examples
| 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.
Side-by-Side Cost Examples
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.

Why Lenders Use Factor Rates
Factor rates serve several purposes for lenders:
- Simplicity: A single number determines total repayment — easier to communicate than amortization schedules
- Revenue certainty: The lender knows exactly how much they will collect regardless of repayment speed
- Regulatory positioning: MCAs structured as receivables purchases rather than loans can avoid usury law application in many states
- Obscures true cost: 1.35 sounds smaller than 71% APR — the factor rate presentation systematically makes the cost seem more palatable than APR disclosure would
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.

Red Flags When You See a Factor Rate
- Provider refuses to disclose APR or "doesn't work that way": Legitimate lenders provide APR on request
- Factor rate presented without term context: Without knowing the repayment term, you cannot calculate APR
- No comparison to alternative products provided: Responsible financing should involve comparing options
- Pressure to decide quickly: "This rate is only available today" — designed to prevent you from comparing alternatives
- Confusion between factor rate and interest rate in sales materials: Presenting 1.35 factor as "35% interest" is misleading
When Factor Rate Products Are Justified
Despite their high cost when properly converted to APR, factor rate products (MCAs) have legitimate use cases:
- True emergency capital needs where no lower-cost option is available within the required timeframe
- Very short-term, high-ROI deployment where the investment return clearly exceeds the factor rate cost
- Businesses that genuinely cannot qualify for any interest-bearing alternative due to credit or history constraints
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.
