Unsecured business loans are fast and accessible — but they're also among the most expensive forms of finance available to small businesses. The problem is that the real cost is often hidden behind unfamiliar terminology. This guide translates it into plain numbers so you can make an informed decision.
How Unsecured Business Loan Costs Are Structured
Unlike a standard home loan where you're quoted an annual interest rate, many unsecured business lenders use a factor rate — a multiplier applied to the principal. This makes it easy to underestimate the real cost.
| Loan Amount | Factor Rate | Total Repayment | Effective Annual Rate (12 months) |
|---|---|---|---|
| $50,000 | 1.15 | $57,500 | ~15% p.a. |
| $50,000 | 1.25 | $62,500 | ~25% p.a. |
| $100,000 | 1.30 | $130,000 | ~30% p.a. |
| $100,000 | 1.40 | $140,000 | ~40% p.a. |
Factor rates don't work like interest. With a standard loan, paying it off early reduces your interest cost. With a factor rate loan, the full cost is often locked in regardless — so paying it off in 6 months doesn't save you 50% of the fee.
Hidden Fees to Watch For
- Establishment fee: 1–3% of the loan amount, charged upfront
- Monthly account keeping fee: $10–$50/month
- Early repayment fee: Often 1–2% of the outstanding balance
- Drawdown fee: Charged each time you draw from a line of credit
- Default fee: Significant penalties for late or missed payments
Interest Rate vs Factor Rate vs APR
| Measure | What It Shows | Limitation |
|---|---|---|
| Interest rate (p.a.) | Annual cost of the outstanding balance | Doesn't include fees |
| Factor rate | Total multiplier on the loan amount | Doesn't show time value — can mislead |
| Comparison rate | Interest + fees combined into a single rate | Most accurate for comparing products |
Always ask for the comparison rate or calculate the annualised percentage rate (APR) before signing. Reputable lenders will provide this. If a lender is reluctant to give you the comparison rate, that's a red flag.
Real Cost Comparison: Bank vs Non-Bank
| Lender Type | Typical Rate / Factor | $100,000 over 12 months: Total Cost |
|---|---|---|
| Bank overdraft | 7–12% p.a. | ~$7,000–$12,000 |
| Bank term loan | 8–14% p.a. | ~$8,000–$14,000 |
| Non-bank (Prospa, Moula) | 15–35% p.a. | ~$15,000–$35,000 |
| Merchant cash advance | Factor 1.2–1.5 | ~$20,000–$50,000 |
When Unsecured Finance Is Worth the Cost
Despite higher rates, unsecured business loans make sense when:
- The opportunity cost of waiting is higher than the finance cost (e.g., a bulk purchase at a 30% discount)
- You need funds within 48 hours and can't wait for bank approval
- You don't have assets to secure against
- The loan is short-term and you can repay quickly
They're typically not the right choice for long-term growth funding or large capital expenditure — where a secured loan or commercial property finance is far cheaper.
Frequently Asked Questions
Almost always, yes. "Unsecured" means no asset collateral — but lenders almost always require a personal guarantee from the director(s). This means you're personally liable if the business can't repay.
Most non-bank lenders cap unsecured loans at $150,000–$500,000. Some will go higher for businesses with strong financials. For larger amounts, lenders typically require property or other security to offer competitive rates.
Often, but check the terms carefully. Factor rate loans may not reduce your total cost with early repayment. Interest rate loans typically will allow early repayment with a potential fee. Always ask specifically before signing.
The interest/fee component is generally deductible as a business expense. Principal repayments are not deductible. Confirm the deductibility of factor rate fees with your accountant as the treatment can vary.
Most non-bank lenders offer same-day or next-business-day approvals for amounts under $150,000. Funds are typically disbursed within 24–48 hours of approval. This speed is one of the main reasons businesses use non-bank lenders despite the higher cost.
