What Is a Factor Rate? How to Calculate the True Cost of Your MCA
By David Chen, Funding Specialist
David Chen is a funding specialist at Merchant Fund Express with expertise in merchant cash advances, working capital solutions, and business financing strategies.
When a funder offers you a merchant cash advance at a "1.28 factor rate," do you know exactly what you'll repay? Most business owners don't — and that lack of clarity costs them tens of thousands of dollars. This guide explains factor rates from first principles, shows you how to calculate total cost and APR, and gives you a framework for evaluating whether a specific offer makes financial sense.

What Is a Factor Rate?
A factor rate is a decimal multiplier that determines the total amount you repay on a merchant cash advance (MCA) or certain short-term business financing products. It replaces the concept of an interest rate with a single, fixed cost expressed as a number between 1.0 and 2.0 (though nearly all real-world offers fall between 1.10 and 1.55).
The math is simple:
// Example: $80,000 × 1.30 = $104,000
Cost of Financing = Total Repayment – Advance Amount
// Example: $104,000 – $80,000 = $24,000
That's it. No compounding. No variable rates. No prepayment penalties in most cases. The total cost is locked in on day one — which is both the main advantage and the main limitation of factor rate financing.
How Factor Rates Differ from Interest Rates
Traditional loans use interest rates — a percentage applied to the outstanding balance over time. Interest compounds or accrues based on how long the money is outstanding. Pay off a 10% annual-rate loan in 6 months and you pay roughly 5% of principal. Factor rates don't work that way.
| Feature | Interest Rate (Traditional Loan) | Factor Rate (MCA) |
|---|---|---|
| Cost structure | Accrues over time on balance | Fixed at origination |
| Compounding | Yes (monthly/daily) | No |
| Early payoff savings | Yes — pays less interest | Usually no |
| Cost expression | % per year (APR) | Decimal multiplier |
| Regulatory framework | TILA, usury laws apply | Generally exempt |
| Calculation complexity | Requires amortization schedule | Single multiplication |
How to Calculate Total Repayment
Use this three-step process every time you evaluate an MCA offer:
Step 1: Calculate Total Repayment
// $100,000 × 1.35 = $135,000
Step 2: Calculate Dollar Cost
// $135,000 – $100,000 = $35,000
Step 3: Calculate Cost as Percentage of Advance
// (1.35 – 1) × 100 = 35%
Full Example Table
| Advance | Factor Rate | Total Repayment | Dollar Cost | Cost % |
|---|---|---|---|---|
| $25,000 | 1.15 | $28,750 | $3,750 | 15% |
| $50,000 | 1.20 | $60,000 | $10,000 | 20% |
| $75,000 | 1.28 | $96,000 | $21,000 | 28% |
| $100,000 | 1.35 | $135,000 | $35,000 | 35% |
| $200,000 | 1.25 | $250,000 | $50,000 | 25% |
| $500,000 | 1.18 | $590,000 | $90,000 | 18% |
Converting Factor Rate to APR
To compare an MCA against a bank loan or line of credit, you need to convert the factor rate to an annual percentage rate (APR). Here's the formula:
Step 2: Daily Rate = Cost % ÷ Term in Days
Step 3: APR = Daily Rate × 365
// Example: 1.30 factor, 180-day term
Step 1: (1.30 – 1) × 100 = 30%
Step 2: 30% ÷ 180 = 0.1667% per day
Step 3: 0.1667% × 365 = 60.8% APR
APR Reference Table by Term Length
| Factor Rate | APR (90-day term) | APR (180-day term) | APR (365-day term) |
|---|---|---|---|
| 1.15 | 60.8% | 30.4% | 15.0% |
| 1.20 | 81.1% | 40.6% | 20.0% |
| 1.25 | 101.4% | 50.7% | 25.0% |
| 1.30 | 121.7% | 60.8% | 30.0% |
| 1.40 | 162.2% | 81.1% | 40.0% |
| 1.50 | 202.8% | 101.4% | 50.0% |
Note: APR values assume uniform daily repayment. Actual APR varies based on repayment timing. These figures are estimates for comparison purposes.
The key takeaway from this table: the same factor rate produces very different APRs depending on term length. A 1.25 factor rate on a 12-month MCA translates to 25% APR — comparable to a business credit card. The same rate on a 3-month MCA exceeds 100% APR. Short terms amplify APR dramatically even when the dollar cost is identical.
Factor Rate Ranges: What's Normal?
Factor rates are not standardized across the industry. Here is a realistic breakdown of what to expect:
| Rate Range | Classification | Typical Borrower Profile |
|---|---|---|
| 1.10 – 1.18 | Excellent | Strong revenue, 2+ yrs, 650+ credit, low advance relative to monthly revenue |
| 1.19 – 1.27 | Good | Solid revenue, 1+ yr, 580+ credit, moderate advance |
| 1.28 – 1.36 | Average | Decent revenue, some risk factors (credit, industry, advance size) |
| 1.37 – 1.45 | Below average | Higher-risk profile: thin margins, recent delinquencies, or volatile industry |
| 1.46 – 1.55+ | High risk pricing | Bad credit, very short business history, previous defaults, or stacked debt |
What Affects Your Factor Rate?
Factor rates are set by funders based on underwriting criteria that assess the likelihood and consistency of repayment. The primary variables are:
1. Monthly Revenue and Consistency
This is the single most important factor. Funders want to see consistent monthly deposits, preferably with month-over-month growth. Volatile revenue — large swings up and down — signals risk and pushes rates higher. Average monthly deposits of $40,000 with low variance will get a better rate than $40,000 average with 40% variance.
2. Credit Score
While MCAs are credit-flexible, credit score still influences pricing. A 650+ score may earn a 1.15–1.20 rate. A 550 score on the same advance may push to 1.30–1.38. The difference on a $100,000 advance is $10,000–$18,000 in additional cost.
3. Time in Business
Established businesses (2+ years) represent lower risk and command better rates. Businesses under 12 months face higher rates due to statistical default risk. Two years in business versus six months can mean a 0.05–0.10 reduction in factor rate.
4. Advance Amount vs. Monthly Revenue
Funders typically advance 50–150% of your average monthly revenue. Staying closer to 75–100% of monthly revenue earns better rates. Requesting 200%+ of monthly revenue signals strain and will push factor rates higher — or result in a smaller offer.
5. Industry Risk
Some industries carry higher default rates and are priced accordingly. High-risk industries include construction, trucking (variable loads), restaurants (thin margins), and seasonal businesses. Stable industries like medical, legal, and SaaS command the lowest rates.
6. Existing Debt Load
If you already carry significant debt — other MCAs, equipment loans, lines of credit — funders will price in the risk of over-leverage. Businesses with clean, debt-free bank statements get the best rates.
How to Compare MCA Offers
Never accept the first offer you receive. Follow this comparison framework:
| Comparison Point | Offer A | Offer B | Offer C |
|---|---|---|---|
| Advance Amount | $100,000 | $100,000 | $85,000 |
| Factor Rate | 1.30 | 1.25 | 1.20 |
| Total Repayment | $130,000 | $125,000 | $102,000 |
| Dollar Cost | $30,000 | $25,000 | $17,000 |
| Term (approx) | 6 months | 8 months | 6 months |
| Daily Payment | $1,083 | $781 | $708 |
| Approx APR | 60.8% | 45.6% | 40% |
| Best choice if... | Need max capital quickly | Balance of capital + cost | Cost minimization priority |
In this example, Offer C costs $13,000 less than Offer A — but delivers $15,000 less capital. Whether that trade-off makes sense depends entirely on what you're using the capital for and what return you expect it to generate.
Key Takeaways
- Factor rate = decimal multiplier. Total repayment = advance × factor rate. That's it.
- Factor rates of 1.10–1.25 are competitive; 1.40+ is high-cost territory
- Unlike interest rates, factor rate cost does NOT decrease if you repay early (in most cases)
- Converting to APR requires knowing the term length — the same factor rate produces wildly different APRs depending on term
- Your revenue consistency, credit score, and advance-to-revenue ratio are the primary rate drivers
- Always get 2–3 competing offers and compare on total dollar cost, not just factor rate
- The right factor rate question isn't "is this cheap?" — it's "does the ROI of this capital exceed the cost?"
Frequently Asked Questions
What is a factor rate?
A factor rate is a decimal multiplier used to calculate the total repayment on a merchant cash advance or short-term business loan. A factor rate of 1.30 means you repay $1.30 for every $1.00 borrowed.
How do I calculate total repayment from a factor rate?
Multiply the advance amount by the factor rate. Example: $75,000 × 1.30 = $97,500 total repayment, meaning the cost is $22,500.
What is a good factor rate?
Factor rates of 1.10–1.25 are considered good. Rates of 1.26–1.35 are average. Rates above 1.40 are high-risk pricing and should only be accepted if no better option exists.
How do I convert a factor rate to an APR?
Calculate total cost, divide by advance to get decimal cost, divide by term in days, multiply by 365, then multiply by 100. Example: $30,000 cost on $100,000 over 180 days = 30% ÷ 180 × 365 = ~60.8% APR.
Why do MCAs use factor rates instead of interest rates?
MCAs are legally structured as a purchase of future receivables, not a loan. Factor rates reflect a fixed purchase discount rather than time-value interest, which is why they don't compound and don't change based on how quickly you repay.
Does paying off an MCA early save money?
Usually no. Unlike loans with accruing interest, the total repayment on an MCA is fixed by the factor rate from day one. Early payoff does not reduce the total dollar cost — but it does improve your effective APR.
What factors affect my factor rate?
Key factors include: credit score, monthly revenue amount and consistency, time in business, industry risk, existing debt obligations, and the advance amount relative to monthly revenue.
Can I negotiate my factor rate?
Yes. Funders have rate ranges, not fixed prices. Strong revenue, longer business history, and clean bank statements all support negotiating a lower factor rate. Getting multiple quotes is the best strategy.
