A factor rate is the single number that determines what your funding costs. If you're looking at a merchant cash advance, a revenue-based advance, or any short-term business funding product, the factor rate is the number you need to understand. Everything else -- daily remittance, total repayment, effective cost -- flows from it.
Most people who search "factor rate" have already seen one on an offer sheet and want to know what it means. So here's the short version: take the amount you're receiving, multiply it by the factor rate, and that's what you pay back total. A 1.25 factor rate on $50,000 means you repay $62,500. The $12,500 difference is the cost of capital.
That's it. The rest of this article covers why it works this way, how to compare it to other pricing, and how to tell whether the number on your offer is fair.
The Math in Plain English
A factor rate is a decimal number, usually between 1.10 and 1.50. You multiply it by the funding amount to calculate total repayment. There's no compounding, no amortization schedule, no variable rate. One multiplication.
Example 1:
Funding: $50,000
Factor rate: 1.20
Total repayment: $50,000 × 1.20 = $60,000
Cost of capital: $10,000
Example 2:
Funding: $100,000
Factor rate: 1.35
Total repayment: $100,000 × 1.35 = $135,000
Cost of capital: $35,000
Example 3:
Funding: $25,000
Factor rate: 1.15
Total repayment: $25,000 × 1.15 = $28,750
Cost of capital: $3,750
The total repayment amount is fixed at signing. Whether you repay in 4 months or 8 months, the total stays the same. This is fundamentally different from a loan where interest accrues over time.
Factor Rate vs. APR: Why They're Different
APR (annual percentage rate) measures the cost of borrowing over a year. It accounts for compounding, payment timing, and amortization. It's how banks price loans. A 10% APR business loan means you're paying roughly 10% of the outstanding balance per year, but the actual cost depends on how the payments are structured and how long you hold the debt.
A factor rate doesn't work that way. There's no outstanding balance that accrues cost over time. The total cost is locked in on day one. A 1.30 factor rate on $100,000 costs $30,000 whether you repay it over 4 months or 9 months.
This makes factor rates simpler to understand but harder to compare directly to loans. If you want to convert a factor rate to an approximate APR, the formula is:
Approximate APR = ((Factor Rate - 1) / Repayment Term in Years) × 100
Example: 1.30 factor rate, 6-month term
(0.30 / 0.5) × 100 = 60% APR
Example: 1.20 factor rate, 4-month term
(0.20 / 0.333) × 100 = 60% APR
Example: 1.15 factor rate, 8-month term
(0.15 / 0.667) × 100 = 22.5% APR
These APR numbers look high. They are high. An MCA is more expensive than a bank loan. That's the honest truth. A bank term loan at 8-12% APR costs significantly less in raw dollars. The tradeoff is speed and accessibility. The bank takes 60-90 days and denies 82% of small business applicants. An MCA funds in 24-48 hours with no minimum credit score.
The relevant comparison for most business owners isn't MCA vs. bank loan. It's MCA vs. no capital at all, because the bank already said no.
Why MCA Uses Factor Rates Instead of Interest
A merchant cash advance isn't a loan. It's a purchase of your future receivables at a discount. There's no loan principal accruing interest over time. The funder buys a portion of your future revenue at a set price.
Because there's no principal balance, traditional interest rate math doesn't apply. The factor rate sets the total purchase price upfront. You know exactly what you'll repay before you sign anything. No surprises six months in.
This structure also means repayment typically happens through a small daily remittance -- a fixed dollar amount or a percentage of daily sales. If your revenue dips, a percentage-based remittance dips with it. The total repayment stays the same, but the timeline stretches.
What Affects Your Factor Rate
Factor rates aren't random. They're risk-based. A funder sets the rate based on how likely you are to repay consistently and on time. Here are the specific variables.
Time in Business
Longer track record, lower rate. A business with 3 years of operating history has proven it can survive seasonality, recessions, and bad months. A business open 7 months hasn't. At Westline, the floor is 6 months. Businesses with 18+ months of history typically see meaningfully better rates.
Monthly Revenue
Higher revenue means more room for a daily remittance without straining cash flow. A business depositing $80,000/month can absorb a $400/day remittance without blinking. A business doing $18,000/month feels that same $400 hard. Higher revenue usually translates to lower factor rates because the risk of cash flow disruption is lower.
Cash Flow Consistency
Steady deposits month to month get better rates than volatile swings. If your bank statements show $30,000, $32,000, $29,000, $31,000 over four months, a funder sees stability. If they show $45,000, $12,000, $38,000, $8,000, they see unpredictability. Seasonal businesses aren't automatically penalized -- the funder just needs to see the pattern is seasonal and not erratic.
Industry
Some industries have higher failure rates than others. Restaurants are riskier than dental practices. Construction is seasonal. Trucking has fuel cost volatility. Funders adjust rates by industry based on historical repayment data across thousands of accounts.
Existing Obligations
If you already have an active advance or significant debt payments, your available cash flow shrinks. More obligations on the same revenue means higher risk, which means a higher factor rate. This is also why stacking multiple advances is dangerous -- each one raises the cost of the next.
Typical Factor Rate Ranges
- Strong profile (18+ months open, $40K+/mo revenue, consistent deposits, clean bank statements): 1.15 - 1.25
- Moderate profile (6-18 months, $15K-$40K/mo, some seasonal variation, minor NSFs): 1.25 - 1.35
- Higher risk (newer business, lower revenue, inconsistent deposits, existing obligations): 1.35 - 1.50
If someone offers you a factor rate above 1.50, scrutinize the deal carefully. Rates that high are usually reserved for businesses with serious red flags. Make sure you understand the total cost and can handle the daily remittance before signing.
If someone offers you a factor rate below 1.10, also scrutinize it. That's unusually low for an MCA and may come with hidden fees, a confusing repayment structure, or terms that aren't what they seem.
When Factor Rate Funding Makes Sense
The single question to ask: will this capital generate more revenue than it costs?
A contractor gets a $180,000 project but needs $40,000 upfront for materials. $40,000 at a 1.25 factor rate = $50,000 total repayment. The $10,000 cost of capital nets him $130,000 in gross profit on the project. Good math.
A landscaping company needs $20,000 for a new mower that will let them take on 8 additional accounts worth $2,400/month each. The $20,000 at a 1.30 factor rate costs $6,000 in fees. The mower generates $19,200 in new annual revenue. The funding pays for itself in under 4 months.
A trucking company needs $15,000 to repair a rig that's been sitting idle for two weeks. The rig generates $8,000/month in revenue. Every day it sits is $267 lost. The $15,000 at a 1.25 factor rate costs $3,750 in fees. Two weeks of idle time already cost $3,738. The funding is cheaper than the delay.
When It Doesn't Make Sense
If the capital goes toward something with no revenue return, the math usually fails. Taking $30,000 at a 1.35 factor rate to cover last quarter's tax bill means paying $40,500 total. The taxes needed to be paid either way, and now you owe $10,500 more than you would have with a payment plan from the IRS. (IRS installment plans charge roughly 8% annually -- much cheaper than a factor rate.)
Using capital to cover operating losses without fixing the underlying problem makes things worse. If your business loses $4,000/month, a $25,000 advance adds a daily remittance on top of the existing shortfall. You burn through the capital, still lose $4,000/month, and now owe $7,500 in fees on top of it.
The honest assessment: if you can get a bank loan, get a bank loan. It's cheaper. If the bank says no or takes too long and you have a revenue-generating use for the money, a factor rate deal can make financial sense. If there's no revenue opportunity on the other side of the funding, think twice.
How to Evaluate an Offer
When you receive an offer with a factor rate, check four things:
1. Total repayment. Multiply funding amount by factor rate. This is the number that matters most. Make sure you can stomach paying back this total amount.
2. Daily remittance as a percentage of revenue. Divide the daily remittance by your average daily revenue. Keep this under 10%. Above 10% and your cash flow will feel tight. Above 15% and you're in danger territory.
3. Hidden fees. Some providers add origination fees, closing fees, or admin fees on top of the factor rate. At Westline, the factor rate includes everything. Ask your funder if there are any additional charges before signing.
4. Revenue return. What will you do with this capital? If the answer generates revenue that exceeds the cost of capital, you have a defensible financial decision. If it doesn't, reconsider.
Frequently Asked Questions
What is a factor rate?
A decimal multiplier that determines total repayment on a merchant cash advance. Multiply the funding amount by the factor rate to get the total you repay. $50,000 at 1.25 = $62,500 total. The $12,500 difference is the cost of capital.
What's a good factor rate?
Strong profiles (18+ months in business, $40K+/mo revenue) typically see 1.15 to 1.25. Moderate profiles land at 1.25 to 1.35. Higher-risk businesses see 1.35 to 1.50. Below 1.10 is suspiciously low. Above 1.50 is expensive.
How do I convert a factor rate to APR?
Approximate formula: ((factor rate - 1) / repayment term in years) × 100. A 1.30 factor rate over 6 months is roughly (0.30 / 0.5) × 100 = 60% APR. This is an estimate because MCA uses daily remittances, not monthly installments.
Does paying back faster reduce the total cost?
Usually not. The factor rate sets a fixed total repayment. $50,000 at 1.25 = $62,500 whether repayment takes 4 months or 7 months. Some funders offer early payoff discounts, but this varies. Ask before signing.
Why do MCAs use factor rates instead of interest?
A merchant cash advance isn't a loan. It's a purchase of future receivables. There's no loan principal accruing interest. The factor rate sets the total cost upfront so you know exactly what you'll repay before you sign.
