Why This Matters More Than You Think
Understanding the difference between APR and factor rate is not academic — it is the difference between knowing your true cost of capital and potentially overpaying by thousands of dollars. According to a 2025 survey by the Small Business Borrowers' Bill of Rights coalition, 67% of small business owners could not accurately estimate the total cost of their most recent loan.
The confusion is deliberate. Some lenders advertise costs using whichever metric looks more favorable for their product. A merchant cash advance with a 1.3 factor rate sounds affordable until you realize the equivalent APR might be 60-80% if repaid over 6 months. Conversely, quoting APR on a short-term product can make a cost-effective option look absurdly expensive.
This guide cuts through the confusion. By the end, you will know exactly how each metric works, how to convert between them, and — most importantly — how to calculate the one number that tells you the truth about any loan offer.
What Is APR (Annual Percentage Rate)?
APR stands for Annual Percentage Rate. It represents the total annualized cost of borrowing, expressed as a percentage of the loan amount. APR includes not just the interest rate but also fees (origination, processing, closing costs) spread over the loan term.
How APR Is Calculated
APR accounts for compounding interest and the time value of money. A simplified formula:
APR = ((Total Interest + Fees) / Loan Amount) / Number of Years x 100
This is simplified — the actual Truth in Lending Act (TILA) calculation is more complex and accounts for the amortization schedule, but the principle is the same.
APR Example
You borrow $100,000 at 12% APR for 3 years with a 2% origination fee:
- Interest over 3 years: ~$19,600 (amortized)
- Origination fee: $2,000
- Total cost: ~$21,600
- Monthly payment: ~$3,322
- Total repayment: ~$119,600
Key characteristic: APR decreases your effective cost if you pay early. Because interest accrues over time, paying a 12% APR loan off in 18 months instead of 36 months significantly reduces total interest paid.
Who Uses APR
- Banks and credit unions
- SBA lenders
- Online term loan providers
- Business line of credit providers
- Equipment financing companies
What Is a Factor Rate?
A factor rate is a decimal multiplier applied to the amount you borrow to calculate the total fixed repayment amount. Factor rates typically range from 1.1 to 1.5 for business funding.
How Factor Rates Work
The calculation is simple multiplication:
Total Repayment = Loan Amount x Factor Rate
Factor Rate Example
You receive $100,000 with a 1.3 factor rate:
- Total repayment: $100,000 x 1.3 = $130,000
- Total cost: $30,000
- If repaid over 12 months: ~$542/day or ~$10,833/month
- If repaid over 6 months: ~$1,083/day or ~$21,667/month
Key characteristic: The total repayment amount is fixed regardless of how quickly you pay. Whether you repay in 4 months or 12 months, you still owe $130,000. This means paying early does NOT save you money (unless your contract specifically includes an early payoff discount, which some do).
Who Uses Factor Rates
- Merchant cash advance providers
- Some revenue-based financing providers
- Short-term business funding companies

| Feature | APR | Factor Rate |
|---|---|---|
| What it measures | Annualized cost of borrowing | Total repayment multiplier |
| Interest type | Compounding (calculated on declining balance) | Fixed (calculated on original amount) |
| Early payoff benefit | Yes — less interest accrues | Usually no — total amount stays the same |
| Includes fees | Yes (by regulation) | Not always — fees may be separate |
| Typical range | 5% – 40% for business loans | 1.1 – 1.5 for MCAs/RBF |
| Transparency | Standardized by TILA | No standardized disclosure requirement |
| Best for comparing | Long-term loans | Short-term funding |
How to Convert Factor Rate to APR (and Vice Versa)
Converting between factor rate and APR requires knowing the repayment term. Here is the approximate conversion formula:
Estimated APR = ((Factor Rate - 1) / Repayment Term in Years) x 2
The "x 2" accounts for the fact that you are paying down the principal over time, so the effective rate is roughly double what a simple interest calculation would suggest.
Conversion Table
| Factor Rate | Repayment Period | Total Cost on $100K | Approximate APR |
|---|---|---|---|
| 1.15 | 6 months | $15,000 | ~60% |
| 1.15 | 12 months | $15,000 | ~30% |
| 1.25 | 6 months | $25,000 | ~100% |
| 1.25 | 12 months | $25,000 | ~50% |
| 1.30 | 6 months | $30,000 | ~120% |
| 1.30 | 12 months | $30,000 | ~60% |
| 1.40 | 9 months | $40,000 | ~107% |
| 1.40 | 12 months | $40,000 | ~80% |
| 1.50 | 12 months | $50,000 | ~100% |
Critical insight: Look at how the APR changes dramatically based on repayment period, even though the factor rate and total dollar cost stay the same. A 1.25 factor rate looks like 100% APR over 6 months but only 50% APR over 12 months. Same total cost ($25,000), completely different APR. This is why comparing factor-rate products to APR-based products using APR alone can be deeply misleading.
Real-World Cost Comparisons
Let us compare three actual offers a business owner might receive for $75,000 in funding:
| Metric | Bank Term Loan | Online Lender | MCA |
|---|---|---|---|
| Amount | $75,000 | $75,000 | $75,000 |
| Stated Cost | 10% APR | 22% APR | 1.35 factor |
| Term | 3 years | 18 months | 10 months |
| Origination Fee | 1.5% ($1,125) | 3% ($2,250) | $0 |
| Net Proceeds | $73,875 | $72,750 | $75,000 |
| Monthly Payment | $2,420 | $4,640 | $10,125 |
| Total Repayment | $87,118 | $83,520 | $101,250 |
| Total Cost | $13,243 | $10,770 | $26,250 |
| Time to Fund | 3-6 weeks | 3-5 days | 24-48 hours |
| Credit Required | 680+ | 620+ | 500+ |
The bank loan has the lowest total cost but takes weeks to fund and requires excellent credit. The online lender is actually cheapest in total dollars because of the shorter term, but requires 620+ credit. The MCA costs the most in dollars but is accessible to almost everyone and funds tomorrow.
The right choice depends on your situation: If you have a time-sensitive opportunity that will generate $50,000+ in profit, paying $26,250 for capital that arrives in 24 hours is a far better decision than saving $13,000 by waiting 6 weeks for a bank loan — and missing the opportunity entirely.

The Only Metric That Never Lies: Total Cost of Capital
Forget APR. Forget factor rates. The one number that lets you compare any two offers on a perfectly level playing field is Total Cost of Capital (TCC).
TCC = Total Repayment Amount - Net Cash Received
This tells you in plain dollars how much you are paying for the privilege of borrowing money. No conversions needed. No misleading comparisons. No tricks.
Before accepting any offer, ask the lender three questions:
- How much cash will I actually receive after all fees?
- What is the total amount I will repay over the life of this agreement?
- Is there a prepayment discount if I pay early?
The difference between answers 2 and 1 is your total cost of capital. Compare that number across all your offers to make the best decision.
10 Questions to Ask Every Lender Before Signing
- What is the total amount I will repay?
- What is the APR or factor rate?
- Are there any origination, processing, or closing fees?
- Is there a prepayment penalty or prepayment discount?
- What is the daily/weekly/monthly payment amount?
- How long is the repayment term?
- Are payments fixed or do they vary with revenue?
- What happens if I need more time to repay?
- Is there a renewal option and at what terms?
- What fees apply if I miss a payment?
