When comparing business loan options in Australia, you will encounter two very different ways that lenders express the cost of borrowing: factor rates and interest rates. They may seem like two versions of the same thing, but they work quite differently - and misunderstanding the distinction can lead to costly decisions.
This guide breaks down how each pricing model works, when you are likely to encounter them, and how to compare them so you can make informed choices about your business financing.
What Is an Interest Rate?
An interest rate is the more familiar of the two. It is a percentage charged on the outstanding balance of a loan over a specified period, usually expressed as an annual figure.
How Interest Rates Work
With an interest-bearing loan, you are charged interest on the remaining principal balance. As you make repayments and reduce the principal, the amount of interest you pay decreases over time.
Example: You borrow $50,000 at an interest rate of 15% over 12 months with monthly repayments.
- In month 1, interest is calculated on the full $50,000
- By month 6, your principal has reduced significantly, so the interest charged that month is lower
- By month 12, you are paying interest on only a small remaining balance
The total interest paid over the life of the loan depends on how the repayments are structured (principal and interest vs interest-only periods) and whether the rate is fixed or variable.
Where You Will See Interest Rates
Interest rates are the standard pricing model for:
- Traditional bank business loans
- Commercial property loans
- Lines of credit
- Overdraft facilities
- Longer-term business loans (typically 2+ years)
- Equipment finance (often expressed as a flat or reducing rate)
Most Australian business owners are familiar with interest rates because they are used on home loans, credit cards, and savings accounts.
What Is a Factor Rate?
A factor rate is a decimal multiplier applied to the total amount borrowed to determine the fixed total repayment amount. It is not calculated on the outstanding balance - it is applied once, upfront, to the original loan amount.
How Factor Rates Work
Factor rates are typically expressed as a number between 1.1 and 1.5, though they can fall outside this range depending on the product and risk profile.
Example: You borrow $50,000 at a factor rate of 1.25.
- Total repayment = $50,000 × 1.25 = $62,500
- Total cost of borrowing = $62,500 − $50,000 = $12,500
- If repaid over 12 months with weekly repayments: $62,500 ÷ 52 = approximately $1,202 per week
The critical difference is that the $12,500 cost is fixed from day one. It does not decrease as you repay the loan. Whether you repay over 6 months or 12 months, you owe $62,500 in total (unless the lender offers an early repayment discount, which some do).
Where You Will See Factor Rates
Factor rates are common on:
- Short-term business loans (3 to 18 months)
- Merchant cash advances
- Revenue-based financing products
- Some online lender products designed for fast approval and settlement
These products are typically used for working capital, bridging cash flow gaps, or seizing time-sensitive business opportunities.
Comparing the True Cost: Factor Rate vs Interest Rate
Comparing a factor rate to an interest rate directly is like comparing kilometres to miles - they measure the same underlying thing (cost of borrowing) but use different scales. To make an informed comparison, you need to convert them to a common measure.
Method 1: Total Cost of Borrowing
The simplest comparison is to look at the total dollar cost of each loan option.
Scenario: You need $50,000 for 12 months.
| Interest Rate Loan | Factor Rate Loan | |
|---|---|---|
| Amount borrowed | $50,000 | $50,000 |
| Rate | 15% interest | 1.15 factor rate |
| Total repayment | ~$54,200 | $57,500 |
| Total cost | ~$4,200 | $7,500 |
Even though “15%” and “1.15” might seem similar at first glance, the total cost is quite different. This is because the interest rate is calculated on a reducing balance, while the factor rate is applied to the full original amount.
Method 2: Annualised Percentage Rate
To compare loans of different terms, converting to an annualised percentage rate provides a standardised measure. However, this calculation is more complex for factor rate products because the effective rate depends on the repayment term and frequency.
A factor rate of 1.25 over 12 months equates to a much higher annualised cost than it might initially appear. The same factor rate over 6 months is even higher on an annualised basis, because you are paying the same dollar cost over a shorter period.
Approximate annualised equivalents for a 1.25 factor rate:
- Over 12 months: approximately 45% annualised
- Over 6 months: approximately 90% annualised
- Over 3 months: approximately 180% annualised
These figures illustrate why it is so important to look beyond the headline number and understand the actual cost structure.
Method 3: Cost Per Dollar Borrowed
Another practical approach is to calculate how much each dollar of borrowing costs you.
- Factor rate of 1.25: Every $1 borrowed costs $0.25
- Factor rate of 1.15: Every $1 borrowed costs $0.15
- Interest rate of 15% over 12 months (reducing balance): Every $1 borrowed costs approximately $0.08
This gives you a quick, intuitive sense of the relative cost.
When Factor Rates Make Sense
Despite the higher cost when converted to an annualised rate, factor rate products are not inherently a bad deal. They serve a specific purpose and can be the right choice in certain situations.
Speed and Accessibility
Factor rate products - such as fast business loans - are typically designed for speed. Applications can be assessed and funded within 24 to 48 hours, compared to weeks or months for traditional bank loans. If you need capital quickly to cover a payroll shortfall, secure a bulk purchase discount, or bridge an unexpected gap, the speed of access can more than offset the higher cost.
Lower Eligibility Barriers
These products often have less stringent eligibility requirements than traditional bank loans. Businesses with shorter trading histories, lower turnover, or imperfect credit may find it easier to qualify for a factor rate product than a traditional interest rate loan.
Simplicity and Predictability
Factor rates offer total cost transparency from the outset. You know exactly how much the loan will cost and exactly what your repayments will be. There are no variable rate surprises, no fluctuating monthly payments, and no compounding interest calculations to track.
Short-Term Use
When used for genuinely short-term purposes - bridging a 3 to 6 month cash flow gap, for example - the total dollar cost of a factor rate product may be quite manageable, even if the annualised equivalent looks high.
When Interest Rates Are the Better Option
For longer-term borrowing, interest rate products almost always work out cheaper.
Larger Loan Amounts
On larger loans, the dollar difference between a factor rate and an interest rate becomes substantial. On a $200,000 loan, the difference could be tens of thousands of dollars.
Longer Repayment Periods
If you need 2 to 5 years to repay a loan, an interest rate product on a reducing balance will cost significantly less than a factor rate applied to the full amount.
Strong Credit Profile
If your business has a solid trading history, strong financials, and good credit, you are likely to qualify for competitive interest rate products. A small business loan with an interest rate structure will typically be more cost-effective for established businesses.
Asset-Backed Lending
If you can offer security (property, equipment, or other assets), interest rate products become even more competitive because the lender’s risk is reduced.
Common Mistakes When Comparing Loan Costs
Mistake 1: Comparing the Numbers Directly
A factor rate of 1.15 is not equivalent to a 15% interest rate. As shown above, the total cost is materially different. Always convert to a common measure before comparing.
Mistake 2: Ignoring Fees
Both factor rate and interest rate products may include establishment fees, administration fees, or early exit fees. These need to be included in your total cost comparison. Ask every lender for a full breakdown of all fees and charges.
Mistake 3: Not Considering Early Repayment
With an interest rate loan, paying the loan off early directly reduces your total interest cost because interest stops accruing on the repaid principal.
With a factor rate loan, the total cost is typically fixed regardless of when you repay - unless the lender offers an early repayment discount. Always ask whether early repayment reduces the total cost, and get the terms in writing.
Mistake 4: Focusing Only on the Rate
The cheapest loan is not always the best loan. Consider the full picture:
- How quickly can you access the funds?
- What are the eligibility requirements?
- How flexible are the repayment terms?
- What happens if you need to restructure?
- Is the lender responsive and easy to deal with?
Sometimes a slightly more expensive product that you can access quickly and repay flexibly is a better business decision than a cheaper product that takes weeks to arrange.
How to Evaluate a Business Loan Offer
When you receive a loan offer - whether it uses a factor rate or interest rate - ask these questions:
- What is the total amount I will repay? This is the single most important number
- What is the total cost of borrowing? Total repayment minus the amount borrowed
- What are the fees? Establishment, ongoing, and exit fees
- What is the repayment schedule? Weekly, fortnightly, or monthly - and how much each time
- Is there an early repayment benefit? Can I reduce the total cost by paying faster
- What happens if I miss a payment? Late fees, default interest, or other penalties

Making the Right Choice for Your Business
The right pricing model depends on your specific situation:
- Need funds fast for a short-term purpose? A factor rate product may be the practical choice
- Planning a larger, longer-term investment? An interest rate loan will likely be more cost-effective
- Comparing two offers? Always convert to total cost of borrowing and factor in all fees
The most important thing is to understand what you are being quoted, ask the right questions, and compare on a like-for-like basis.
